Overused of LED as for Decorative Light

This is a ceiling lighting of a Large Department store in Tsuen Wan District,
They have been using over three thousand cold white K2 LED modules. Its is a new traction for the entrance of the store. It is gorgeous!
However, I am thinking are we going to wrong direction? The main purpose using LED is to cut off extra power consumption and reduce CO2 emission, but this kind of decorative light would easier eat up 3000W of Electricity… and that is a lot of light contamination it may product tons of CO2 to our world.. Well, I think the architect should also think of the right amount of LED lighting, or the intention of Power harvest of LED would become Power Wastage!

Simple way is to apply some Light guides which could then reduce the number of LED modules as much as 60% or more and retaining the same Lighting Effect! Besides, if they use RGB LED , there could be more fun as they can create a lot of gimmick such as mood lighting, light shows...

The LED Man

This Coat consists of LEDs mounted on flex boards joining with control switches, wires and battery cells. Designed by Daves Forbes as he called The LED TV Coat.
There is some gimmicks for this to be used for mobile Advertisement in the street at night.
May be fashion clothing at Disco! I think the power source is an issue.
If 160x120 LED means 19,200 LED, that each consume say each 50 mill watts power. That is a lot of power for lighting up 19K pieces of LEDs, he might need to change battery every 40 minutes. Unless he carry a big storage power, but his idea is niche and eye catching.

Vertigo Bird Balloon

Vertigo Bird is a Slovenian Company designs and manufacture the Lighting Fixture.
LED Balloon is the design that catches my attention, Bold, Simple, beautiful using Efficient LED as a source, LED light shines upwards and enlightens reflector, which re-direct reflecting the light forwards. HK Snob

Replacemetn LED Light bulbs and BLU will drive LED driver IC Market Through 2015

LED driver IC sales will reach nearly $3.5 billion in 2015 from nearly $2 billion in 2010, a compound annual growth rate of 12%. With growth from edge-lit TVs and monitors. LED lighting applications will be the next big event for LED drivers and driver ICs, beginning with replacement bulbs, as a response to improvements in technology and phasing-in bans on incandescent bulbs in many countries.
LED driver IC revenues are threatened by continued integration into fewer ICs, competition from compact fluorescent lamps and OLED. Severe price erosion for driver ICs will limit the revenue growth as volumes increase, but new, higher priced ICs are appearing that reduce the overall BOM and also help maintain the ASP of the ICs. AC-LED products minimize the driver and some eliminate the driver IC, but will not have a significant impact on overall revenues through the period.
The production value of drivers for lighting will see strong 40% compound annual growth through the period. The driver is the entire LED circuit, including the driver IC but excluding the LEDs. Innovations in driver design will help take LED lighting mainstream, but the market will quickly shake out those who cannot meet strict goals for dimming, efficiency, power factor, and price. To meet these goals, large and small companies are bringing innovations to market, such as digital control and novel high-voltage designs. Industry, LED researcher and even energy authority are moving toward more standardized specifications that will reduce manufacturing costs and accelerate adoption.
The top 10 LED driver IC suppliers hold more than 55% of revenues, with about 30 IC suppliers and captive manufacturers sharing the other 44%. With the acquisition of National Semiconductor by Texas Instruments, TI is now the number one supplier of LED driver ICs. Winners will be those who can keep delivering innovative products at competitive prices. Fabrication with leading-edge high-voltage BCD processes and 8”-12” wafers will play a key role. HK Snob
