Ionic thermoelectric film uses body heat to power LED lights
A research team affiliated with UNIST has unveiled a novel thermoelectric (TE) film, capable of powering LED lights using a ...
Thanks to their energy savings, long service life, durability and design flexibility they offer, light emitting diodes (LEDs) are rapidly replacing incandescent and fluorescent technologies in both ...
Recent breakthroughs in LED technology have enabled LEDs with a broad spectrum of light output to be produced and not just the traditional red and green derivatives. Hence the sheer numbers of LEDs ...
Light emitting diodes - semiconductors that emit light - have put light bulbs back on the front page, arguably for the first time since Thomas Edison unveiled his bulb in 1879 to replace for kerosene ...
