Cree XLamp 7090

Avago Technologies
Avago Technologies is an American company which was earlier the semiconductor products division of HP and later Agilent Technologies, before being spun off into a distinct legal entity. It holds more than 2,000 patents.

In late 2005 the semiconductor division of Agilent was acquired by Kohlberg Kravis Roberts and Silver Lake Partners, and became an independent company. Today it is one of the largest privately held semiconductor companies in the world, with approximately 6,000 employees and net revenue of $1.8 billion in fiscal 2005.

Avago Technologies provides a range of analog, mixed-signal and optoelectronic components and subsystems to more than 40,000 customers. Thin Film Bulk Acoustic Resonator (FBAR) filters are produced for mobile phones and WLAN.

Avago is also one of the world largest LED manufacturers. They produce billions of LED a year for different application. Product portfolio covers through holes LED, Surface mount PLCC, Envisium Surface Mount PLCC-4 LED, Moonstone High Power LED, Moonstone High Power RGB LED and various kinds of indicators and displays.
"Avago" is an Australian slang word. It means, "Give it a try - have a go."
Cree Inc.
CREE is a Durham, North Carolina based, American corporation which manufactures semiconductor materials and devices. It was formed in 1987 by researchers from North Carolina State University. Materials products include silicon, Silicon Carbide (SiC) and Gallium Nitride. Device products light-emitting diodes (LEDs) made from their materials for a variety of uses, as well as power supply chips, motor controllers and microwave radios.

The wide band gap semiconductors are suitable for high voltage or high power or high temperature operation. SiC is used for high power electronics, largely due to having a very high thermal conductivity.

Two directors of Cree are John Palmour and Chuck Swoboda.

Cree's high-power LEDs, XLamp 7090 XR-E Q4
Some operations are now located Tai Po Science Park in Hong Kong. The company's silicon fabrication line in Sunnyvale, California is closed, and the company is now focusing on wide band-gap technologies.

The company produced a prototype White LED that can produce 161 lumens per watt while drawing 350mA of current, nearly 10 times what an incandescent (normal) light bulb can produce. As of March 2009, the most efficient white Cree LEDs commercially available, such as the XLamp XR-E R2, achieve 100 lumens per watt. Based on more than 20,000h of continuous testing, Cree estimates that XR-E LEDs will lose 30% of their brightness over a usage period of 50,000h (barring overheating).

Cree bought Cotco Hui Zhou in 2007 with USD$300 Millions , that is another step moving from Chip manufacturing into a highly vertical Integration of Package LED manufacturing.

Cree's competitors include Nichia Corporation, Osram Opto Semiconductors, PhilipsLumiles Lighting Company and GE Lighting (Vio). Cree is also facing increasing competition from low cost Taiwanese LED manufacturers such as Epistar and Everlight.

Everlight Taiwan
Everlight Electronics was established in 1983 and has played a critical role in Taiwan’s LED industry. In 2006 Everlight established itself as number one in terms of market share in Taiwan with second place significantly behind. Liteon In 2007. Everlight Electronics continued to lead the Taiwan market in both total revenue and in revenue growth rate Now. It established itself as the seventh largest LED manufacture in the world.

Everlight Electronics maintains assembly lines in all product series including High Power LEDs, LAMPs, SMD LEDs, Display and Infrared products. In addition to having the complete product series and a large manufacturing capacity, Everlight also integrated vertically by investing in LED optical chip manufacturing in order to maintain a stable supply of chips. Everlight Has factories in Taiwan and China.

Overall, Everlight’s competitive advantage is its manufacturing. The new awarded Product is Dolphin HB LED. Noteworthy is that Everlight unveiled its newest AC LED at the show, which can work without transformers and last for 50,000 hours, and was, scheduled to start shipping the product in the fourth quarter of this year.

Everlight today is a $300 million company headquartered in Taipei, Taiwan, with over 4,000 employees and operations in China, Asia, North America and Europe.

I still recalled that I was the one to install the first two Die bonders in Tucheng Taipei when Everlight was still not as big s today in 1988. How this is the Taiwan Largest LED manufacturing.

Liteon Taiwan
Lite-On started producing LED products in 1975 and has steadily grown into one of the world's largest optoelectronic component manufacturers by providing customers with both visible and infrared product solutions. High volume capacities for commodity items and application specific products, combined with strong R&D and vertical integration, have proven to be key distinguishing factors in Lite-On's success. Our broad product line continues to expand to meet the requirements of emerging markets and new applications. Liteon had factories in Thailand and Tianjin of China.

Lumileds USA
In the late 1990's, recognizing the potential for solid-state lighting, HP and Philips, one of the world's leading lighting companies, began exploring how they could work together and deliver a new solid-state lighting solution to the market. In 1999 HP split its company into two, and the optoelectronics group was assigned to the new Agilent Technologies. In November of the same year, recognizing the enormous potential for LEDs, Agilent Technologies and Philips (NYSE:PHG) formed Lumileds and assigned it the responsibility of developing and marketing the world's brightest LEDs and enabling a new world of light.

In 2005, Philips acquired Agilent Technologies’ interest in Lumileds. Today, the company continues to lead the industry in the development an Philips Lumileds Lighting Company is a fully integrated manufacturer of LED dice, packaged LEDs, and high-brightness LEDs
LUXEON®—designed for integration into general lighting products. The company markets LED solutions designed specifically for automotive applications, LCD displays, general lighting, portable applications, signage, traffic signals, and other segments. Philips Lumileds makes the world's brightest white, red, amber, blue and green LED release of increasingly brighter and technically advanced solid-state lighting technology.

Philips Lumileds' LUXEON® technology enables LEDs to match the brightness of conventional light sources and for the first time, makes it possible to replace incandescent, halogen and fluorescent bulbs in many products with smaller, longer-lasting and more energy efficient LEDs.
Luxeon is the trade name for high power LEDs that dissipate 1 watt or more. Models include Luxeon I, Luxeon III, Luxeon V, Luxeon K2, Luxeon Star, and Luxeon Rebel.
Luxeon LEDs produce powerful light, and are a popular choice among flashlight manufacturers. They are available in many colors, including white. Luxeon is in fact the first kind of an innovation design and had absolutely good thermal design LED.

Probably the only one using TFFC (Thin film Flip Chip) technology for LED manufacturing.
Competitors to Luxeon include Cree Inc., Seoul Semiconductor and Nichia Corporation.

Nichia Japan
The Nichia Corporation (日亜化学工業株式会社, Nichia Kagaku Kōgyō Kabushiki-gaisha) is a Japanese chemical manufacturing company that is most widely known for producing phosphors, including light-emitting diodes (LEDs).

The Nichia Corporation was founded by Nobuo Ogawa (小川 信雄, 1912-2002) in 1956. One of his famous decisions was to support Shuji Nakamura (1954- ) to do research on Gallium Nitride light-emitting diodes when it was generally considered a very risky business. It turned out to be a great success. However, the company achieved a certain amount of notoriety for awarding a bonus of ¥20,000 Yen (US$180) to Shuji Nakamura for his invention of the first high brightness blue-light LED, which was based on Gallium Nitride. Nichia later settled out of court with Nakamura for ¥840 million Yen (US$7 million), in what was then the highest bonus ever awarded by a Japanese company.

After Nobuo Ogawa, the company was headed by Eiji Ogawa (小川英治, son-in-law of Nobuo Ogawa). Nichia Corporation's competitors include Seoul Semiconductor, Cree Inc, and Philips Lumileds Lighting Company.

Osram Germany

The name is derived from Osmium and Wolfram (German for Tungsten), as both these elements were commonly used for lighting filaments at the time the company was founded. OSRAM is a high-tech company in the lighting industry. Around 60 percent of sales come from energy-efficient products. Its was established in 1906, many years before that they have started the manufacturing of Incandescent Light bulb!

Litronix, original backbone and engineering team in Pennag 80’, and Siemens worked with Litronix and used Siemens Litronix since 1989 and then brought all manufacturing equipment from Siemens Malacca to the current Location in Penang with Factory “ Siemens” Then later Changed its name to Osram. Osram has been building LED in Pennag for more than 20 years. Today it is Owned subsidiary of Osram, Lighting manufacturer, a Industrial sector of Siemens. Osram, headquarters in Regensburg, probably the oldest Lighting company in the world. Since 1842.

With its headquarters in Regensburg (Germany), OSRAM Opto Semiconductors is in an excellent position to meet the challenges faced by a global high-tech company. More than 4600 employees throughout the world contribute to the success of OSRAM Opto Semiconductors, producing sales of 529 million Euros in the 2008 fiscal year (as at 30.09.2008). Around 12 percent of the sales of OSRAM GmbH are achieved with semiconductor products.
