Thorlabs provides a range of unmounted, mounted, collimated, and fiber-pigtailed LEDs that emit in the - nm spectral range. Our High-Power LEDs for. Introduction Families of semiconductors can be incorporated into devices that emit light over much of the visible spectrum upon electrical excitation. LED (light-emitting diode) An LED, or light-emitting diode, is a special type of diode that emits light when connected in a circuit. The semiconductor material in LEDs is usually aluminium gallium arsenide (AlGaAs) or indium gallium nitride (InGaN) while the impurities are atoms from another. light-emitting diode (LED), Semiconductor diode that produces visible or infrared light when subjected to an electric current, as a result of. Most white-light diodes employ a semiconductor chip emitting at a short wavelength (blue, violet or ultraviolet) and a wavelength converter, which absorbs light. LEDs, on the other hand, only emit a handful of wavelengths of light. This is because the materials that LEDs are made of, unlike stars or incandescents, are. LED stands for light-emitting diode. An LED is a source of light that is widely used in various ways, especially in electronic devices and equipment. A more.
