This joule thief led or high efficiency LED with 1.5 volt driver is a tried and tested circuit built around some discrete electronics components. A common 5 mm high-efficiency white LED (D1) is the ...

A newly developed white organic light-emitting diode operates at under 1.5 volts, report researchers from the Institute of Science Tokyo. By using triplet–triplet annihilation to generate blue light ...

The LED delivers a 100° beam angle and is housed in a surface-mount chip-carrier package that matches a PLCC-2 footprint. Forward voltage is 1.5-V maximum, with continuous forward current of 50 mA.

Designed for use in applications such as remote control and charge-coupled devices, smoke detectors, and security lighting, a family of IR Series LEDs is optimized to operate at wavelengths of 850, ...
