Light emitting diodes (LEDs) are semiconductors that convert electrical energy into light energy. The color of the emitted light depends on the semiconductor material and composition. LEDs are generally classified into three wavelengths: ultraviolet (UV), visible and infrared. The wavelength range of commercially available LEDs with single-pixel-output power of at least 5mW is 360nm to 950nm. Each wavelength range is made from a specific semiconductor material family, regardless of the manufacturer.
