Improving LED Output
Filed in archive Energy by Dr. Joseph Kim on June 11, 2008

LED flashlights seem to get brighter every few years. Fortunately, the price also seems to be coming down on these super-bright devices that are power-efficient. What's more amazing about LED technology is the low amount of heat generated by such bright lights.
Well, electrical engineering researchers at the University of Hong Kong seem to have found a way to develop brighter LED lights. What's the secret? Answer: hexagonal
-close-packed microspheres. These scientists may have found a way to make even brighter LED lights! So how bright do you think those keychain flashlights can get? Thanks to nanotechweb.org for the story!
