Techopedia Explains Infrared Light Emitting Diode

Unlike LEDs that project parts of the visible light spectrum, IRLEDs are not used to provide lighting. They are, instead, most commonly used in various signal transfer systems, such as in remote controls for televisions, night-vision cameras and other devices. An IRLED beams light with data signals to control the device. IRLEDs are also used in security installations, cameras and other kinds of technologies. They are useful because of their low energy consumption and low heat generation.
