Understanding Infrared LED Emitter

An infrared LED emitter, also known as an infrared LED, is a semiconductor device that emits infrared light. It operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The emitted light is in the infrared spectrum, which is not visible to the human eye but can be detected by various sensors and devices. The key components of an infrared LED emitter include a semiconductor material, a metal contact, and an encapsulation material. The semiconductor material is typically made of gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), which has excellent electrical and optical properties for infrared emission. The metal contact provides an electrical connection to the semiconductor material, while the encapsulation material protects the device from environmental factors and ensures its longevity.
