Panasonic has designed energy efficient LED Bulb that looks like an incandescent
Cause of LED efficiency droop conclusively identified Auger recombination as the mechanism of LED droop a mysterious drop in the light produced when a higher current is applied. The cost per lumen of LEDs has held the technology back as a viable replacement for incandescent bulbs for all-purpose commercial and residential lighting. This could all change now that the cause of LED efficiency droop has been explained.
LED Lights Make Augmented Vision a Reality. University of Washington researchers have figured out how to implant semitransparent red and blue LED lights in contact lenses, for the purpose of receiving and displaying data in sharp visual images and video. This means wearers will literally be able to watch TV or view photos that are projected directly onto their eyeballs. Once miniature green LEDs are developed (and they’re in the works, as of now), full color displays will be possible.
SEIL backpack by Lee Myung Su (www.leemyungsu.com/) uses LED lights to display traffic signals. Simply by controlling the detachable wireless controller, the user can show directional and emergency signals on the back of the backpack. #concept #design #bagpack #bicycle #bike
