HigH Power LED Chip Development

The Above table is measured with a driving current of 350mA. The latest announcement from Cree is 161 Lm/watt which is the most powerful LED so far.

Once if we can achieve 200Lm/Watt, that will be the time for replacement incandescent light bulb by all LEDs.

Comparison of Different type of Back Lit unit


As we know that there is hit for LED TV, though there are different ways for the design for the back light unit, RGB direct back lit, White LED back Lit and White LED edge Lit. Samsung 9 series TV is employing Direct White LED back lit, whereas the other series 8, 7 and 6 series LED TV are all using edge type LED back lit.
As for LG, they have launched the Direct Back light LED LCD TV with thin profile. And they are the hot selling product now.

Sony and Sharp use RGB and RGBplus LED direct back light respectively.
They all have different design; complexity of the lighting control, and number of LED, cost of construction is so much different.

Attached table illustrate the different pros and cons of these different design, I do not yet have the solid data on how to calculate the Dynamic Contrast, as far as I Can tell there is not much difference from human eye to detect the contrast of 100,000:1 and 1,000,000:1 as there may have an insignificant light intensity different comparing between white and absolute darkness.

So far by right the RGB backlit is best in contrast, and picture quality, as they can be tuned up for better crimson RED if we want to, whereas the white direct back lit may not be able to change the degree of hue of the backlight. Since they are using RBG, they colour temperature can be changed by means of the computerized control.

However the RBG control circuitry is much more complex, and the circuitry, cost and power consumption is much higher.

If there is no price concern, why not buy a RGB LED back lit TV, if you are price conscious but do want to have reasonable good quality LCD TV, get a Samsung 8 Series.
If there is no concern on The Picture quality at all! Well, use your CRT TV …that may be good enough already.

LED BLU LCD TV shipment 2009-2011



From the above chart. there are certain interesting data on the LCD TV.
Feom the market that we can see, the majority is still edge type for his simpler design, lower cost for less LEDs to be used and its optimized performance. Samsung is the key player at this Edge lit design.
Samsung is the No.1 Seller in LCD TV.
He is good at Edge Lit TV which is optimized for best performance, cost and probably maintenance performance over the years.

LG is coming up with Direct back lit TV and that will be 2nd hit for best seller… after Samsung Promotion campaign has come to an end by Beginning of July.

Sony and Sharp has their own RBG Direct back lit TV up to 65” that are the beautiful mammoth in your house if your wife allows.

And sooner, Hitachi, Philips, Vizio, Chinese Skyworth and Tsinghua Tongfang and Taiwan TV maker will catch up with lot of LED Backlit TV shipment.

From the shipment, we can see that the LED TV will be ten times more in 2010 than we have in 2009., The number of LED will vary from 400 for edge type back lit to 3,360 pieces or more for a Direct back lit unit. The ASP of the LED will drop about 12% a year.

The bigger the screen size, more the LED on the back lit panel. However when the efficacy is LED is getting higher and higher, the number of LED can be reduced. And I am sure that the Current CCFL TV will be replaced more by LED as for better quality, as a sales gimmick and lower in power consumption.
The penetration rate can to 10% a year, current the LED BLU TV is just 2% of the total LCD TV and reaching 3% by end of 2009. By 2010 the penetration rate will move up to 8% and by 2011 18%, and 2013 about 28%.
That will be Billions dollar business for the LED makers, LED assembly Houses.

LED Back Lit TV and Demand for Package LED

It has been a bore consumer Electronics market in the past three years! Did you see anything new or evolutional in these past three years? Except the best hand set gadget for electronics freak, Iphone that really created a hit since the first launch June 28 2007.


New concept and probably the best product in the last decade. Close follower Samsung, HTC, Sony Ericsson had similar function as iPhone with touch screen and huger display. A bit disappointed to see there is no more new breakthrough on the 3G iPhone!

Hope Steve Job could recover and would bring us some more new inspiration to this electronics world of consumer products, which might trigger the whole semiconductor cycle to turn faster!

Hi End Audio products is running in extreme, such as a gold/silver power cable is selling with $3,000-$5,000, an special liquid Nitrogen chilled IEC power socket is selling at $60.00! A Value of $150 Silver Foil capacitor as one of the 50 components inside A power amplifier! A Vacuum tube mono block power amplifier is selling at $50,000 with less than 30 major components. Where as a China White Box maker can have complete DTS 5.1 system with price tag of $100.00!

Super Audio CD? MP3? There seems only lesser people is able tell the difference of hi frequency timbre on a $300 MP3 or $30 MP3 or the built in MP3 sound quality in a hand set. IPod is rather an image of American cult, beside a tool of music player.

Sony just celebrated its 30th anniversary of Walkman since the launch on 1 July 1979. At that time the mammoth Walkman was selling at $300.00 and they have produced over 40 millions so far. “Walkman” has became a Name in Handy music player and it has entered the Dictionary. Now they have to announce a launch a new generation Walkman type of MP3 player let se how it can beat the IPod!

DC that is already flooding the market with that we can get now is 12MP, 3.8" display at a price of $250.00. Three is a slim chance for a new technology that is readily help is us to have an improvement on the picture equality. Blue Ray, with of 2X better quality than the high definition DVD picture. In order to reproduce the razor edge sharpness picture formed by those millions colors video signal, that might need a super LED Back Light display panel,


What is the next vibrant product in the consumer’s electronics? That is one of the drives of people who eager to invest and produce the best Panel Display of LCD using this LED technology. General speaking, because our Human eye can distinguish much effective than our human ear can tell for the music details. There is no one to argue the ambiguity in distinguishing the difference of the display quality once you compare tgen side to side.

Samsung belief
Speed is the key to all perishable commodities from sashimi to mobile phones. Even expensive fish becomes cheap in a day or two. For both sashimi shop and digital industry, inventory is detrimental and speed is everything.
Jong-Yong Yun, CEO of Samsung Electronics

TV Gadget
LED back lit as good contract, 1D or 2D local dimming, Power saving 40%, slim display and no mercury in the back light unit.

TV makers believe that TV is more than a necessity and people are looking new technology, cost performance and a slim sleek design for Asian residence is so limited in space at living, dinning and sleeping rooms where they used to place a TV. Power saving is a long term return for electric fee and more comfortable to play when there is less CO2 emission being generated because of your TV.

Domestic illuminations accounts 22%, Air Con for 34%, fridge for 14%, and TV take as much as 7.3% of total monthly electricity bill amount. As For TV which consumes as much 7.3% of electricity, we could not underestimate the Green TV would have create much less CO2 emission every night you are watching your big screen TV! As there are billions of this picture box ( now I should say picture panel) being switched on every moment.

LCD TV shipment
The Q109 World TV shipment drop 6% comparing with last quarter Q308. Revenue of Q109 World TV slashes 12%. LCD TV shipment comparing with last quarter rose 27% but the sales Revenues of LCD TV slash for the first time.

The major reason behind is the World Economy Tsunami causes the supplier to reduce the ASP in order to stimulant the consumers

Electronic Times analyses amongst all sizes of TV, 32” is the most popular model partly due the consumer spending limitation and the price drop is most significant for this size 32” TV drop 38% in price whereas 40/42 “only drops trivial 0.5%! Comparing with last Quarter Q408, Samsung has been sales No. 1 for Consecutive 13 Quarters. With amazing market share 22% and LGI is the 2nd runner up of market share of 13% which had surpassed Sony by 2%.

LG Electronics (LG) unveiled two new ultra-slim "full LED" LCD TVs in Seoul 15 July. The new 55-inch screens –- models 55LH95 and 55LH93 respectively –- lead the market in terms of picture quality, design and convenience. LG's ambitious new product line offers a brighter and clearer screen than competing products thanks to backlighting that 3360 LEDs- seven times more than existing edge-lit LED TVs. LG's full LED LCD models also features a 5,000,000:1 contrast ratio through enhanced dimming technology that divides the screen into 240 blocks with 14 Leeds being placed in one block. And with a refresh rate of 240 Hz, these TVs maintain a vibrant, smooth image even during fastest motion action picture scenes. Third is Sony, then Sharp and Panasonic as the 3rd, 4th and 5th position. From DisplayResearch, World shipment of Q1 was 4,330 Million sets. Drop 25% as Q4 08. Drop 6% as comparing with Q108. Total revenues are USD22.1B! Slash 12%.

LCD TV shipment 2,670 M sets that is 61.6% of the total TV sets produced. This is the only one growth.

Market Size of LED back light TV
Forecasting that the global LED LCD TV market will grow to 30 million units by next year and to 68 million by 2011, up from 3.1 million this year. LG is aiming to become the world's second biggest seller of LCD TVs and predicts that the proportion of LCD TVs that feature LED technology will also grow from 2.6 percent this year to 20 percent next year and to 40 percent by 2011.


Market Size 3.1 M sets 2009, 30M sets in 2010, and 68 M sets in 2011. There will be huge LED package LED demand for filling up the back lit panel of the LCD TV. It may need 2.5M LED per hour for all these LCD TV markers. by time Q409.

Price Erosion, Subcon and new comers
Obviously The Taiwan LCD people are not doing anything with this piece of fat meat in on the hot Tapanyaki plate. They will do their best to beat down the price, with volume production in such as scale that may draw Korean giant to further either outsource their LED to other people, and at same time to maintain certain level of Production for maintaining certain safety stock, base on a healthy and conservative plan, They should outsource 40% of their LED into at least three difference sources in at different locations to avoid the political instability that will incur shipment problem and to facilitate a better logistic control.


In coming 3-6 months, Korean, Taiwan or China, OEM will come up with a series of LED TV product in order to keep their LED TV cost down and to maintain good profit margin. Definitely there will be similar or much cheaper TV coming for the World factory from those big names, Skyworth TCL Changhong and Shinco…(Skyworth is China largest TV maker last year his product of CRT TV dropped 30% to 3.75M sets and LCD TV rose 100% to 2.47M sets! ) using low cost LED side lit back light unit, we can anticipate that there will be at last 5 new comers to participate with faster speed than those big players currently shipping product with a higher price tag.


China TV maker would try to pump out some non LED back lit TVs with labeled LED TV with some of the low end product line selling at lower cost. They might not have that kind of reliability and quality as the Korean and Japanese dominant players at first but within 1-2 years they will catch up and occupying bigger portion for the Low Mid end market which is usually 80% of the whole. Let’s watch out.

Vintage over night

“On one new year’s eve, I was celebrating at a restaurant with a bunch of friends and I decided to order a glass of red wine to accompany the countdown.

I randomly chose one and it went well to welcome in the new Year.
We stayed until after midnight and I ordered another glass f same red wine.

When it came to time to leave. I got my bill and noticed my second glass of the same wine cost more, I consulted the waiter, who told me that after midnight, the wine was technically one year older and had now become a “decade-old wine” – as compared to the original, unimpressive nine-year vintage- which, according to restaurant policy, costs more.

I’m happy to report that restaurant is closed now!”

Philips New Acquisition

Royal Philips Electronics has acquired yet another company, Manchester, N.H.-based Teletrol Systems specializes in the design and manufacture of building lighting control centers with over 10,000 building sites around the world.

LED 3D TV


NewSight, a Japanese unit of NewSight Corp of the US, developed a 3D display using LEDs as pixels for the first time in the world.


The 3D effect is caused by an array of parallax LEDs turned at a pitch of 6mm, thereby working in the same way as pixels on LCD displays.


Featuring a 180-inch screen with a width of 3.84m, the "3D LED Video Wall" is one of the world's largest 3D displays. The company said that it is possible to combine four displays and make a 360-inch 3D display.


The new LED display realized 3D representation with the parallax barrier method as the company's LCD 3D displays. The LEDs are made in China. Arranged at a pitch of 6mm, they work like the pixels of an LCD panel. The display is best watched from about 5m away, but the optimal distance can be adjusted. The warranty period of the LED is 20,000 hours.

Pricing is subject to individual order requirement and Quantity.

2nd Generation Philips Master LED




Incandescent lamps convert only the 5% of the electricity into actual light, with most of the remaining 95% being turned into heat energy. This inefficient use of energy led Philips call for incandescent lamps to be phased out. Enforced by European Legislation, this outdated lighting technology will no longer be available for consumers to buy from stores within the European Union from September 2009 onwards.

LED lamps save more than 80% energy consumption, yet they produce the same light level experience as incandescent lamps. The lifetime of LED lamps is more than 40 times longer too, making them environmentally the best alternative to incandescent lamps.

The second generation of MASTER LED will be available from April onwards in the professional distribution channel. The new range will build on the successful introduction, in 2008, of Philips’ MASTER LED range, consisting of 7 pieces of 1W Rebel LED lamp each as a quality alternative to incandescent light bulbs up to 40W and 35W halogen spotlights.
Moreover Philips provides the new Ledino and DayWave lighting system for architectural interier illumination. The Ledion has a sleek new wave design.

LED and Cancer treatment

LED technology has provided medicine with a new tool capable of delivering light deep into tissues of the body. Certain wavelengths which are found to be biologically optimal for cancer treatment and wound healing. This LED technology has already flown on Space Shuttle missions, and shows promise for wound healing applications of benefit to Space Station astronauts.

Following radiotherapy for breast cancer, women exposed to pulses of low-energy non-thermal light-emitting diode photomodulation had significantly less dermatitis than controls.
LED photomodulation is widely used in cosmetic dermatology for improving skin healing and appearance. The apparatus consists of light-emitting diodes in a specific array that emit a non-thermal, low energy light at a pulsating frequency.

The pulses stimulate at the cellular level skins cells such as fibroblasts to repair themselves to build up the collagen.The other thing is that they interfere with the inflammatory pathways that break down the skin and cause erythema.

Photodynamic Therapy (PDT) is a cancer treatment modality that recently has been applied as adjuvant therapy for brain tumors. PDT consists of intravenously injecting a photosensitizer, which preferentially accumulates in tumor cells, into a patient and then activating the photosensitizer, with a LED light source.


The development of more effective light sources for PDT of brain tumors has been facilitated by applications of space light-emitting diode array technology: thus permitting deeper tumor penetration of light and use of better photosensitizers. Lutetium Texaphyrin (Lutex) is a new, second generation photosensitizer that can potentially improve PDT for brain tumors. Lutex has a major absorption peak at 730nm, which gives it two distinct advantages. Longer wavelengths of light penetrate brain tissue easily so that larger tumors could be treated, and second, the major absorption peak means that more of the drug is activated upon exposure to light.

Our experiments suggest potential for using LED light therapy at 680, 730, and 880 nm simultaneously, plus hyperbaric oxygen therapy, both alone and in combination, to accelerate the healing process in Space Station missions, where prolonged exposure to microgravity may otherwise retard healing

LED Cities

LED Streetlight in Ann Arbor Mich.

Studies suggest that a complete conversion to the lights could decrease carbon dioxide emissions from electric power use for lighting by up to 50 percent in just over 20 years; in the United States, lighting accounts for about 6 percent of all energy use. A recent report by McKinsey & Company cited conversion to LED lighting as potentially the most cost effective approaches to tackling global warming using existing technology.

LED lighting was once relegated to digital display in laboratory, public ultilities office, Stock exchange display, basketball scoreboards, traffic lights. But as a result of rapid developments in the technology, it is now poised to become common on streets and in buildings, as well as in homes and offices. Some American cities, supported by LED companies promoted images with name of LED City including Ann Arbor, Mich., and Raleigh, N.C., are using the lights to illuminate streets and parking garages, and dozens more are exploring the technology.

There is a Website 18seconds.org is calculating and updating the number of purchased CFL light bulbs since 1 Jan 2007 in cities and states of USA. It said that it takes just 18 seconds to change an incandescent light bulb to CFL bulb as anintermediate transition for LED illumination.

From the data, Washington is the first Oregon the second and Wisconsin the third largest State as users for CFL.

LED is 2 times more efficient as compact fluorescent bulbs, currently the standard for greener lighting. Unlike compact fluorescents, LEDs turn on quickly and are compatible with dimmer switches. And while CFL contain mercury, which requires special disposal, LED bulbs contain no toxic elements, and last much 3 times longer.

Infrared Stealth Goggles


EyeClops Night Vision goggles (http://www.jakkspacific.com/) power actual infrared driven technology of 17 IR LEDs that shine a wide beam of infrared light up to 50 feet away in completely dark environments. Avalable at your local toy store USD80.00.

Happy Marriage

A couple was celebrating their Pearl wedding anniversary.

Their domestic tranquility had long been the talk of the town, "What a peaceful and loving couple."

A local newspaper reporter was inquiring as to the secret of their long and happy marriage. "Well, it dates back to our honeymoon," explained the man.

"We visited the Grand Canyon and took a trip down to the bottom of the Canyon by pack mule. We hadn't gone too far when my wife's mule stumbled. My wife quietly said, 'That's once.'

We proceeded a little further and the mule stumbled again. Once more my wife quietly said, 'That's twice.'

We hadn't gone a half-mile when the mule stumbled the third time. My wife quietly took out a revolver from her purse and shot the mule dead!

I started an angry protest over her treatment of the mule, when she looked at me and quietly said, 'That's once.'

Then we lived happily ever after."

Oximetry Sensor


Masimo, the innovator and leader of motion and low perfusion tolerant pulse oximetry, Healthy term neonates were monitored with pulse oximetry immediately before, during, and after, circumcision procedures.
A pulse oximeter is a device intended for the non-invasive measurement of arterial blood oxygen saturation (SpO2) and pulse rate. Oximeters are used medically by patients with asthma, chronic obstructive pulmonary disease (COPD)...

Since the general availability of pulse oximeters in the 1970's, many thousands of lives have been saved. Pulse oximeter has become a critical piece of instrument in healthcare industry.

The small, light weight Sensor was built with a couple of nanometer wave length sorted LED chips bonded on one side and receiver chips on the other. The measurement is taken with a few seconds. It is widely used in Hosiptals for detection of oxygen and CO level in blood. The reading is accurate, fast.

LED and Planting


LED lights are popular artificial lighting systems used in hydroponic or soilless gardening. Some of the advantage of these grow lights include better growth of plants, less heat production and low maintenance cost.

Nabesei Co Ltd, a company specializing in electronic parts, demonstrated plants grown under different LED lights took place from April 15 to 17, 2009, in Tokyo.


Plants of the same size were continuously irradiated with light from a lighting device equipped with 630nm red LEDs, a device with 430nm blue LEDs and a pink-colored LED light composed of half red LEDs and half blue LEDs.


After three weeks of irradiation, the growths of the plants were compared with one another. As a result, it was discovered that the pink LED light most effectively promotes the growth of plants, the company said.


Plant do not need all wavelengths in the visible light range for their growth, but they absorb light with certain wavelengths to grow. When they perform photosynthesis or come into bloom, red light around a wavelength of 660nm, which is the absorption peak for chlorophyll, promotes the growth.


Meanwhile, when the plants form flower buds, blue light around a wavelength of 450nm promotes the growth.


When comparing the plants under the three kinds of light, those under the red LED light grew slower than others and were smaller as a whole. The plants under the blue LED light had fewer leaves and were spindly on the whole. On the other hand, the plants under the pink LED light had larger leaves and had generally grown in a more balanced way.


So there is a lot of DOE (Design of Experiment) in order to find out which wavelength would be best for the growth of the plants.


LED does contribute in Gardening and planting industry!

Cree CEO Chuck Swoboda Participated in Presidential Roundtable on American Innovation and Clean Energy Technology


Chuck Swoboda and other CEOs representing American companies at the forefront of innovation were invited to meet with President Obama on 2 July to discuss American innovation in areas such as clean energy and the potential benefits to the U.S. These 8 Companies is Applied Material, Cree, Dow Corning, FPL Group, Hara, Hycrete, Positive Energy and Standard Renewable Energy.

President Obama commented on his meeting: “I just held a meeting with the CEOs of some of the most innovative energy companies in America to talk about growth and progress of a sector that represents a big piece of America's economic future.”

He continued, “These are folks whose companies are helping to lead the transformation towards a clean energy future. Even as we face tough economic times, even as we continue to lose jobs, the CEOs here told me that they're looking to hire new people, in some cases to double or even triple in size over the next few years. They are making money and they are helping their customers save money on the energy front.”

Asked about the message to small businesses, President Obama remarked, “Small businesses should probably contact some of these CEOs because it turns out they can save small businesses and large businesses alike up to 20 or 30 percent on their energy usage.”

Cree, being supported by Obama government would be in a very favourable situation in further expanding his LED chips development and packaging assembly vertical integration in China.
The Tallest one stood at the last row is Chuck.

A Liberated Man

A man was sick and tired of going to work every day while his wife stayed home. He wanted her to see what he went through so he prayed: 'Dear Lord: I go to work every day and put in 8 hours while my wife merely stays at home. I want her to know what I go through. So, please allow her body to switch with mine for a day Amen!'

God, in his infinite wisdom, granted the man's wish. The next morning, sure enough, the man awoke as a woman He arose, cooked breakfast for his mate, Awakened the kids, Set out their school clothes, Fed them breakfast, Packed their lunches, Drove them to school, Came home and picked up the dry cleaning, Took it to the cleaners And stopped at the bank to make a deposit, Went grocery shopping, Then drove home to put away the groceries, Paid the bills and balanced the check book. He cleaned the cat's litter box and bathed the dog. Then, it was already 1P.M. And he hurried to make the beds, Do the laundry, vacuum, Dust, And sweep and mop the kitchen floor. Ran to the school to pick up the kids and got into an argument with them on the way home. Set out milk and cookies and got the kids organized to do their homework. Then, set up the ironing board and watched TV while he did the ironing. At 4:30 he began peeling potatoes and washing vegetables for salad, breaded the pork chops and snapped fresh beans for supper.

After supper, He cleaned the kitchen, Ran the dishwasher, Folded laundry, Bathed the kids, And put them to bed. At 9 P.M .. He was exhausted and, though his daily chores weren't finished, he went to bed where he was expected to make love, which he managed to get through without complaint.

The next morning, he awoke and immediately knelt by the bed and said: - 'Lord, I don't know what I was thinking. I was so wrong to envy my wife's being able to stay home all day. Please, oh! Oh! Please, let us trade back. Amen!'

The Lord, in his infinite wisdom, replied: 'My son, I feel you have learned your lesson and I will be happy to change things back to the way they were.

You'll just have to wait nine months, though. You got pregnant last night.'

Good Trade

Mary was driving home from one of her business trips in Northern Arizona when she saw an elderly Navajo woman walking on the side of the road.

As the trip was a long and quiet one, she stopped the car and asked the Navajo woman if she would like a ride. With a silent nod of thanks, the woman got into the car.

Resuming the journey, Mary tried in vain to make a bit of small talk with the Navajo woman. The old woman just sat silently, looking intently at everything she saw, studying every little detail, until she noticed a brown bag on the seat next to Mary. 'What in bag?' asked the old woman.

Mary looked down at the brown bag and said, 'It's a bottle of wine. I got it for my husband.' The Navajo woman was silent for another moment or two. Then speaking with the quiet wisdom of an elder, she said: 'Good trade.....'

Bill Gates Rules

Bill Gates recently gave a speech at a High School about 11 things they did not and will not learn in school. He talks about how feel-good, politically correct teachings created a generation of kids with no concept of reality and how this concept set them up for failure in the real world.

Rule 1: Life is not fair - get used to it!

Rule 2: The world doesn't care about your self-esteem. The world will expect you to accomplish something BEFORE you feel good about yourself.

Rule 3: You will NOT make $60,000 a year right out of high school. You won't be a vice-president with a car phone until you earn both.

Rule 4: If you think your teacher is tough, wait till you get a boss.

Rule 5: Flipping burgers is not beneath your dignity. Your Grandparents had a different word for burger flipping: they called it opportunity.

Rule 6: If you mess up, it's not your parents' fault, so don't whine about your mistakes, learn from them.

Rule 7: Before you were born, your parents weren't as boring as they are now. They got that way from paying your bills, cleaning your clothes and listening to you talk about how cool you thought you were. So before you save the rain forest from the parasites of your parent's generation, try delousing the closet in your own room.

Rule 8: Your school may have done away with winners and losers, but life HAS NOT. In some schools, they have abolished failing grades and they'll give you as MANY TIMES as you want to get the right answer. This doesn't bear the slightest resemblance to ANYTHING in real life.

Rule 9: Life is not divided into semesters. You don't get summers off and very few employers are interested in helping you FIND YOURSELF. Do that on your own time.

Rule 10: Television is NOT real life. In real life people actually have to leave the coffee shop and go to jobs.

Rule 11: Be nice to nerds. Chances are you'll end up working for one

Another perspective

Jack and Max are walking from religious service. Jack wonders whether it would be all right to smoke while praying.

Max replies, "Why don't you ask the Priest?"

So Jack goes up to the Priest and asks, "Father, may I smoke while I pray?”

The Priest replies, "No, my son, you may not! That's utter disrespect to our religion."

Jack goes back to his friend and tells him what the good Priest told him.

Max says, "I'm not surprised. You asked the wrong question. Let me try."

And so Max goes up to the Priest and asks, "Father, may I pray while I smoke?”

To which the Priest eagerly replies, "By all means, my son. By all means.

You can always pray whenever you want to."

Revolution of Illumination


LED was one of the greatest Invention in 20 Century, where Incandescent light bulb was no question one of great inventions in 19 Century. It may be time to ban Edison's venerable, now vilified, light bulb. European leaders, green pundits and the widely reported light bulb provisions of the U.S. Energy Independence and Security Act of 2007 all urgently push the abandonment of incandescent bulbs. People started collect 100W incandescent light bulb as after another 20 years, the youngster may not understand what Light bulb was. As those young blokes under 25 years ago may not see what Vinyl LP is although this is still the best format for music and audio reproduction in term of high fidelity in this world of technology. As in the Hi end Audio market 20% of the player has his own LP equipment and 40% with vacuum Tubes amplifier which almost went extinct in 1986. Incandescent light bulbs will not the same case as Vinyl as its intrinsic low efficacy will kill itself.


Semiconductor light emitting diodes (LEDs) are finally on the verge of having the capability to radically alter the entire lighting landscape with staggering improvements in both lighting efficiency and efficacy. The high-power LED emerges directly from the same semiconductor, digital infrastructure and intellectual property that brought us iPhones, laptops, hybrid cars, PSP, Xboxes, Net book and LED Back light LCD TV. Though the word "Revolution" has been devalued by overuse, quite irony, the LED is probably only the third revolution in illumination technology since the invention of fire at Stone Age. Until now, there have been only three illumination technologies: fire, from first rubbing stick to produce, torches, tallow and wax candles and, later, whale oil lamps; kerosene lamp, electric incandescence, famously perfected in 1879.

About 12 billion electric lights use Edison bulbs; one third is in the U.S. So, lighting up the world consumes about 2 trillion kilowatt-hours annually. This is in fact equivalent of nearly a billion tons of coal annually. In the U.S., half of that is in fact coal. U.S. lighting uses the equivalent of 50% of the energy used by all cars on American roads.


In Hong Kong, Electricity Bill domestic illuminations accounts 22%, Air Con for 34%, fridge for 14%, and TV take as much as 7.3% of total monthly electricity bill amount. Over the year, there is practical no raise of electricity fare. The cost of illumination has almost collapsed. It is 1,000 times cheaper to light up a room today than at the beginning of the 1910’s, and 10,000 times cheaper than in 1850. Consequently, appetites have soared for the central product of illumination technology, lumens. Humans consume 40,000 trillion lumen-hours per year.


LEDs are fabricated from various concoctions of "compound" semiconductors, mainly gallium and indium. All older forms of illumination use brute force to heat something till it glows. The central difference with an LED is that photons are emitted by designing exquisitely precise semiconductor junctions, tuned just so to employ efficient quantum phenomena that emits photons. It's the quantum equivalent of using butane lighter instead of rubbing sticks to start a fire.

Commercial LEDs were quickly introduced by 1968 after Nick Holonyak, a GE engineer nvented it in 1962. Early ones dribbled out pathetically small flows of lumens and were ridiculously inefficient, converting fewer watts to lumens than even the notoriously inefficient incandescent bulb. The tiny, solid, robust and very long-lived LED was ideal for instrument and indicator lights, cockpit of an aircraft and my expensive Boluva LED digital watches. Price of a 2nd hand Toyota car in 1978.

Over the years, scientists and wafer epitaxial engineers rapidly developed the machinery of photonic semiconductors, suitable manufacturing process and better selection of material. Today's LEDs are 1,200 times more efficient than they were in 1968. LEDs have followed called Haitz's Law, named after the LED researcher Roland Haitz. The law says LED brightness doubles every 18 to 24 months.

Currently, LEDs have already achieved 100 lumens per watt, Incandescent bulbs yield some 15 lumens a watt, CFLs about 80. Without considering the cost impact, in fact, LED is the time for replacing all illumination world wide!

Applications for LEDs have followed their rising power and declining cost, from instrument displays in the early days, to traffic signals and automobile brake lights and interiors, to back-lighting mobile phones and LCD screens, signature decorations. The very first few Blue 5mm LED Vertical lamp was selling at USD50.00 a piece and how is about USD0.2 in the retail electronics shops.


Annual global sales of high-brightness LEDs already total $5.5 billion with 400 million on Illuminations, even before invading the 40,000 tera-lumen market for general illumination. General illumination is currently supplied about equally by incandescent bulbs (dominant in residential markets) and fluorescents (dominant in commercial buildings).


With the lumen power in hand and costs declining, there is one last hurdle for LEDs to overcome in order to conquer general illumination. The reason most people have resisted and will resist using CFLs, and that also currently impedes LED adoption (particularly for indoor lighting) is the quality of the light. CFLs must achieve the light quality of incandescence to enjoy wider adoption.
All lumens are no more equal than all calories are. The eye, like the palate, is exquisitely sensitive to quality. 500 hundred calories at beef doesn't taste the same as 500-calorie foie gras. 500 lumens from a CFL is visually harsh and makes food and people look unnatural, compared with the same 1,000 from Edison's incandescence.


Optical scientists cleverly named the visible mix rendered by the colors in light the Color Rendering Index. The CRI gold standard is numerically 100, the color of pleasing Edison incandescence. A CRI below 90 is noticeably nasty to the eye. CFLs produce and are essentially stuck.


But LED lights have been inching up the CRI curve. LED Lighting Fixtures, for example, just started selling a 12-watt product with a pleasing 92 CRI that looks like a standard 60-watt indoor floodlight and uses 50% less energy than a CFL.


Longer life time 100,000 hours for better cost obvert the years of the life time, small and robust, can be used on various compact and dynamic application such as automobile aircraft, electronic controllable intensity and colour variation, faster response for display such as Back light unit for LCD TV, automobile front lamp for Safety concern.


CFLs contain tiny amounts of mercury. Individually not much, but billions add up, and no one really believes recycling will keep all that mercury out of landfills.


Obama is promoting the green source of energy, does not man he does not has the point, as all kind of wars after the Vietnam is mostly related to oil resources A clever move would be invest more GPD into the greener energy production rather than on the military expensive. That may have a better return., and human will rely les sin the oil which would be the major income in the Middle East. Thought its is easy to say but hard to make it materialization, as when less people buy oil, they will automatically reduce the oil price and if the oil price drops to certain level, that will have leverage effect on running for new greener energy sources.


Any way, only national decision for long term could bring LED into real substitutes for CFL and incandescent lamps. When I bought my first Motorola star TAC hand phone in 1990, it was almost $2,000, no one who imagine that the kind of hand phone will eventually easier to buy one and much faster to expand his user network than the traditional land line in 10 years time.


Every says the LED cost if high, and from all history of electronics life cycle, the LED ASP is dropping as an average of 12% with volume of 20% more producing each year, and the ASP drop is more eminent over the last three years. We will see after 2012, an High-power LED will be just 20% of Today’s.

As we can see that the technology will bring down the price, three years ago the most extensively used Die bonder AD830 in LED industry was running at 10,000 an hour, and now the new die bonder is running at 18,000 unit a hour for the same type of package under same process. I should say the LED equipment supplier would be one of major contribution to lower the ASP of the LEDs.

A Well Planned Retirement

A Well-Planned Retirement*From The London Times:*

Outside the Bristol Zoo, in England, there is a parking lot for 150 cars and 8 coaches, or buses.

It was manned by a very pleasant attendant with a ticket machine charging cars £1 (about $1.40) and coaches at £5 (about $7).

This parking attendant worked there solid for all of 25 years. Then, one day, he just didn't turn up for work.

"Oh well", said Bristol Zoo Management - "we'd better phone up the City Council and get them to send a new parking attendant..."

"Err ... no", said the Council, "that parking lot is your responsibility."

"Err ... no", said Bristol Zoo Management, "the attendant was employed by the City Council, wasn't he?"

"Err ... NO!" insisted the Council.

Sitting in his villa somewhere on the coast of Spain, is a bloke who had been taking the parking lot fees, estimated at about $560 per day at Bristol Zoo for the last 25 years.
Assuming 7 days a week, this amounts to just over $7 million!

And no one even knows his name.....

The Next CEO

A successful business man was growing old and he knew that it was time to choose a successor to take over the business. Instead of choosing one of his Directors or his children, he decided to do something different. He gathered all the young executives in his company together.

He said, 'It is time for me to step down and choose the next CEO.
I have decided to choose one of you.

'The young executives were shocked, but the boss continued. 'I am going to give each one
of you a “seed” today - one very special SEED. I want you to plant the seed, water it, and come back here one year after with what you have grown from the seed I have just given you.
I will then judge the plants that you bring, and the one I choose will be the next CEO.'

One man, named Jim, was there that day and he, like the others, received a seed. He went home and excitedly, told his wife the story. She helped him get a pot, soil and compost and he planted
the seed. Everyday, he would water it and watch to see if it had grown. After about three weeks, some of the other executives began to talk about their seeds and the plants that were beginning to grow.

Jim kept checking his seed, but nothing ever grew.
Three weeks, four weeks, five weeks went by, still nothing.
By now, others were talking about their plants, but Jim didn't have a plant and he felt like a failure.

Six months went by -- still nothing in Jim's pot. He just knew he had killed his seed. Everyone else had trees and tall plants, but he had nothing. Jim didn't say anything to his colleagues, however...
He just kept watering and fertilizing the soil - He so wanted the seed to grow.

A year finally went by and all the young executives of the company brought their plants to the CEO for inspection.

Jim told his wife that he wasn't going to take an empty pot, but she asked him to be honest about what happened. Jim felt sick to his stomach, it was going to be the most embarrassing moment
of his life, but he knew his wife was right. He took his empty pot to the grand board room. When Jim arrived, he was amazed at the variety of plants grown by the other executives... They were beautiful --in all shapes and sizes. Jim put his empty pot on the floor and many of his colleagues laughed, a few felt sorry for him!

When the CEO arrived, he surveyed the room and greeted his young executives.

Jim just tried to hide in the back. ‘What great plants, trees, and flowers you have grown,' said the CEO. 'Today one of you will be appointed the next CEO!'

All of a sudden, the CEO spotted Jim at the back of the room with his empty pot. He ordered the CTO to bring him to the front. Jim was terrified. He thought, 'The CEO knows I'm a failure! May be he will have me fired!'

When Jim got to the front, the CEO asked him what had happened to his seed - Jim told him the story.

The CEO asked everyone to sit down except Jim. He looked at Jim, and then announced to the young executives, 'Behold your next Chief Executive Officer!

His name is Jim!' Jim couldn't believe it. Jim couldn't even grow his seed. 'How could he be the new CEO?' the others said.

Then the CEO said, 'One year ago today, I gave everyone in this room a seed. I told you to take the seed, plant it, water it, bring it back to me today. But I gave you all boiled seeds; they were dead - it was not possible for them to grow.

All of you, except Jim, have brought me trees and plants and flowers. When you found that the seed would not grow, you substituted another seed for the one I gave you. Jim was the
only one with the courage and honesty to bring me a pot with my seed in it.

Therefore, he is the one who will be the new Chief Executive Officer!'

Future of LED Back Light TV



Scientists, architects, Building designers, lighting fixture manufacturers, Energy saving activists, major consumers for lighting illuminations have much to say about how LED is the “Future of all light!” Will this saying holds true depend on how such an advent technology could blend itself into our human’s daily gear of entertainment. An answer is an arm-stretched reachable as it lies with the latest launch of Samsung LED TV series 6, 7 and 8.

Compare to the former CCFL Cold cathode fluorescent lamp on LCD TV, the LED light is brighter, no heat, last longer and more energy efficient. Samsung has incorporated a LED light-source in order to accentuate a deeper black, more vivid colour, more dynamic contrast, enhanced visual fidelity and faster motion. Charm of Sleek and slimmer design of Crystal body is another selling point for Hong Kong and most of the city inhabitants which do not allow too much space for installing a mammoth “Picture Box” in the living room.

Samsung’s another good ure for their LED TV is power consumption, out of a maximum 5 stars, Samsung LED TV 55B7000 was rated a ‘FIVE’ Stars rating for its energy consumption efficiency. There was a test which employed Power Consumption Meter to indicate the TV power consumption per hour in watts unit. First, tested with True vision program. In the standard mode 110 – 130 Watts is consumed which regard as high efficiency for a 55” TV. When set to the Samsung LED TV to highest power efficiency mode, the meter reads 80 Watts, which rendered us nothing but an amazed finding.

There has been questions on how to tell the difference between the CCFL, Direct-lit and Edge Lit Back Light unit! Refer to the attached illustration, we can see that only Direct-lit LED BLU can have a true 2D local dimming effect. However, its cost is higher, thicker and likely it contained 1-2 PC to control the LEDs!

From various market studies, now the LED BLU TV may have 1-1.5% of the total LCD TV shipment, and this Exploding market will continue to grow , we estimate that there may have a penetration rate of 24 % in 2012. That is a huge number for LCD TV, and that is the real LED market to be!

Currently Samsung is holding up 50% of the LED market of TV and no question that Samsung will be the dominant power for LED on TV in the three years to come if their investment plan
remains as Samsung Success story states as:

A result of focus investment on future product meets the foreseen trend of product cycle!

Top LED Manufacturers




The global light-emitting diode industry is mainly concentrated in Japan, Taiwan, Europe, America, South Korea, China, etc. According to Yano Research 2009, Japan, the largest producer of the light-emitting diode industry in the world, holds 46.6% of the market share.


European and American is the 2nd sector of the world production 18.2%. rest 35.2% is Korea, Taiwanese and Chinese Market. Nichia Corporation is the world's largest provider of the high-brightness light-emitting diodes. Toyoda Gosei Co., Ltd is the world's fourth largest and Japanese is the second largest manufacturer of the light-emitting diodes.


Osram Opto, located in the Europe and America, is the world's second largest and Osram is the largest manufacturer of the high-brightness light-emitting diodes in Europe. Taiwan, the global production base of the consumption electronic products, is mainly engaged in the production of the visible light-emitting diodes. Taiwan is also the world's largest downstream packaging and middle stream chip production base. The Rate of growth is from Korea, Taiwan and China for more than 10% on 2008 as comparing with 2007. This growth is still on!

With more than 30-year development, Chinese light-emitting diode industry has formed the basically complete industrial chains, covering the LED inside, epitaxial wafer, chip package and application. At present, China has over 600 LED enterprises specializing in the downstream packaging and application. But the development of the epitaxial wafer and chip is comparatively backward. There are only about 10 enterprises engaged in the production of the epitaxial wafer for LED, as well as few chip manufacturers. So, the yield capacity enjoys a high degree of concentration. Recently Osram has announced the open ceremony of the first LED wafer fabrication in Penang. That has been one of the ways to enlarge their LED production in Asia. And the first step to shift the manufacturing centre and technology to Asia.

With gradual improvement of the luminous efficiency and application technologies, the light-emitting diodes has been transferred from initial indicator lights to screens, such as the landscape lighting, backlight, automobile lights, traffic lights, lighting areas, etc. The application of the light-emitting diodes is now in diverse development. It is predicted that the average compound growth rate of sales of the display light-emitting diodes will be exceeded 15% in 2006 to 2010 and the annual average compound growth rate of sales of the landscape lighting will reach over 35%, with the annual average compound growth rate of sales of the backlight light-emitting diodes at more than 30%.

In 2010, many patents in the light-emitting diode industry will expire. Chinese enterprises are expected to break through the shackles of the intellectual property rights from European, American and Japanese giants. They should make good use of huge market bases and abundant labor resources in order to occupy a place in the Global LED supplier food chain.


As for technology competence, European and American is the leader in term of Lumen intensity, LED efficacy, Package design, thermal management. Taiwan is a close follower and China is the world fcatory for LED of All types including those USA and Taiwan Set-up. European LED giant is also looking for way to set-up a fcatory in China for import tax redeem purpose.

Today we can see that there is almost one new set-up factory in China for LED every week! Not to believe that is not even get a good balance in demand and supply, however this supply of LED will carry on eroding the ASP of LED, an this is the nature of every electronics component life cycle.

These are the Rank of the LED players in the world in term of revenue of LED product in 2007.

Nichia 21%
Osram 18% (European No.1)
Citizen 7%
TG (Japan No.2)
Lumileds 6.8%
Stanley 6%
Everlight 5.3%
Avago 4.6%
Seoul Semi 4.2%
