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 ...

Anyone who spent some time hanging around film sets at the end of last year, especially in Northern Ireland, would have seen crew wearing “we survived 40 days of nights” sweatshirts. These ...
