Many portable appliances and other products that must operate from a single cell are restricted to working at very low voltages. It is thus difficult to drive white LEDs that typically have a forward ...

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 ...

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 ...

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 ...
