I wondered how we can get bigger lights using the same technology. The first thought is to get an array of LEDs strung together to bring the effect. However such an array looks ugly. They would look like a corn with little bulbs projecting out. Instead what we need is a nice flat surface.
There is all this rage about LED TVs in the market. See

Imagine having LED lights for our entire home. In theory these should reduce energy consumption while offering rich ability to project light - colors, patterns, intensity, etc. Imagine if we can have programmable lighting inside the house. Imagine the lights dancing to the moods, music, and people in the house. That will add a living personality to these lights. What may be required for the same. Need to think about this further.
A quick search through the internet revealed that there are nice panels on the way making to the US market. OLED Light Guide Panels are bright ideas that provide rich way for us to add brightness to our lives. I am committing to buy more LED based lighting products. And of course that means there is more delight waiting for me.
