Unlike incandescent lamps, which emit light over a very broad range of wavelengths, LEDs emit light. LEDs are particularly efficient light sources, used for illumination, optical fiber communications, signal lights and displays. SMD 3528 Infrared Chip LED 940nm Infrared Emitting Diode Radiant Intensity 7. Introduction to Light Emitting Diodes (LEDs) Introduction Light-emitting diodes (LEDs) are promising lighting sources for general lighting applications with the promise of being more than ten times as efficient as incandescent lighting. For years, the creation of incandescent light has been regarded as the greatest act of invention and the most visible part of Edison's creation was the light bulb itself. 5Mm IR Emitter LED Diode Lights , DC 1.

Where to Buy Light-emitting Diodes. LEDs usually wont emit light in a signal path. 00 - Diodes, other than photosensitive or light-emitting diodes (LED) 8541. In light emitting diodes , light is produced by a solid state process called electroluminescence.
