Researchers at The University of Osaka, in collaboration with ULVAC, Inc. and Ritsumeikan University, have developed a new LED structure that generates circularly polarized light from a single chip.

The circuit in Figure 1 allows you to light any type of LED from a single cell whose voltage ranges from 1 to 1.5V. This range accommodates alkaline, carbon-zinc, NiCd, or NiMH single cells. The ...

Sometimes people forget that light-emitting diodes can also detect light quite well. They're usable in a wide range of applications as inexpensive, readily available optical detectors. Typically, an ...

Hyundai Mobis has unveiled a new a HLED that's able to be bent as a thin film. The design allows a single LED to serve as both a stop lamp and a tail lamp at the same time requiring only 5.5mm ...

A LED light pipe is an optical fiber or a solid transparent plastic rod for transmitting light from an LED mounted on a printed circuit board (PCB) to the user interface. Light pipes transmit up to 80 ...
