As many of you may know by now, white LED lights are beginning to replace traditional incadescent and even halogen light bulbs in everyday products such as flashlights. For the same amount of light or more, LED lights consume less power, generate very little heat, and usually last longer than the lifespan of the entire flashlight. So I was thinking. Can this technology be used as a replacement for LCD and DLP projector bulbs? If you've ever changed a projector bulb before, you know it's basically nothing more than a high power light bulb mounted on a removeable cradle with two wires connected between the bulb and the connectors. For something costing hundreds of dollars, you'd expect a bit more for your money. Now imagine if in that same amount of space, you could add a two inch square panel mounted with hundreds or even thousands of tiny white LED lights attached to a power regulator designed specifically for the projector being used. You MIGHT end up with a satisfactory replacement bulb. I say MIGHT because I have no idea if such a concept is even possible. For now, the only white LED lights I seem to find on the Internet are the types that are already installed inside a clear plastic case. What I would need is practically the tiny LED element inside the casing, mounted on a board along with hundreds if not thousands of other identical tiny LED lights. Can a two inch square board packed with thousands of LED lights work as well as a regular projector bulb? Can it give off the same amount of light or more while at the same time give off nowhere near the same amount of heat as a regular bulb? Are there any companies out there that have tried this out yet? What is the smallest size white LED light currently available on the market?
