LED Lights Of Tomorrow 100 Times Smaller?

Think today’s LED lights are efficient? The LEDs of tomorrow could be even more so, using a type of bulb 100 times smaller than those we see today, according to a new study published by researchers at the University of Miami College of Engineering.

The study, entitled “Unusual Strategies for Using InGaN Grown on Silicon (111) for Solid State Lighting,” was published recently online in the Proceedings of the National Academy of Science. It was co-authored by the university’s assistant professor Jizhou Song, who noted that this new LED model is based on a silicon substrate, novel etching strategies, a unique layout and an innovative thermal management method.

Song said, in a statement, “The combination of these manufacturing techniques allows the new design to be much smaller and keep lower temperatures than current LEDs using the same electrical power.”

Song and his fellow researchers see potential applications for this tiny form of solid-state lighting in deformable display monitors and biomedical devices that can adapt to the curvilinear surfaces of the human body.

    Looking for a LED solar lamp that is shaped like a magazine;the back or cover are the solar panels while when open and made to stand u00a0. on edge the inside is filled with LED lamps,so as to give off at least 100 to 125 lumen s for studying students in third world countries.The lamp would take 4 hrs to charge in the sunlightu00a0and give off light for 6 to 8 hours.Could cost from $40 to $75 depending on the luminosity.
