[Petteri Aimonen] created an omnidirectional LED safety light to cling to his child’s winter hat in an effort to increase visibility during the dark winter months, but the design is also great ...

LEDs are more efficient than incandescent lights and can last 100 times longer, but they require specialized electronic-drive circuits to avoid overstress ...

Circuit of the LED solar lantern lights presented here is built around one 6V/1W Solar Panel (PhotoVoltaic Panel) and a 4V/800mAh Lead-Acid Battery. Here, commonly available 5mm White Straw Hat LEDs ...

Suppose we want to drive an LED string with 400 mA. Drivers U1 and U2 (MAX16803) are good for automotive use because they have a high input-voltage range, excellent thermal qualities, and the ...

Electromagnetic emissions from an LED driver thus can be transferred via the power-supply lines as well as magnetically or capacitively coupled into adjacent circuit segments.

LED drivers, with their high-efficiency (>93%), combine with high lumens-per-watt white LEDs to keep the required battery current low. The ability to tailor lighting color is another advantage.

Inspired by printed circuit boards, the building block of all electronics, a Dutch designer has created an LED-based light installation that draws upon the familiar etching pattern inside most ...

What are LED lights? LED stands for light emitting diode, according to energystar.gov. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs.

The Razer Chroma Hardware Development Kit solves that, by offering Chroma-compatible LED light strips that you can add to your custom-built PC rig or really anywhere in your room. Want to cover ...
