Light Emitting Diodes Can Now Concentrate Light Precisely Where Needed

A novel optical component channels the light from light-emitting diodes to the exact place where it is needed.

Anyone heard of this new optic???

It is called a lens. New technology.

Actually looks like it is just a custom lens... They are going to make them to distribute light in a rectangle to illuminate a piece of paper with a desk lamp. Sounds pretty weak honestly. (non news)

I'd have to say one thing from just reading the first few lines: " A one-watt LED delivers roughly the same optical output as a hundred-watt light bulb." They don't know what they are talking about. The whole article (I just skimmed it) seems a bit behind the curve. Focusing the power of an LED is nothing new to flashaholics - see the Aspheric lenses some have used.

Sorry but there is no helping that. That article is is VERY weak. Maybe there is some wonderful breakthrough there and the person who wrote the article did a bad job of conveying it.

Next up. "Researchers find a novel way of producing light by running electricity through a Tungsten wire"

100W light bulb?

That's 1330 lumens.

Sell a 1W LED that pumps that out, and I promise you, I'll buy one.
