Introduction to LED Infrared Technology

LED infrared, or Light Emitting Diode infrared, refers to a type of LED that emits infrared radiation. Unlike visible light, infrared radiation is not visible to the human eye but is detectable by certain sensors and devices. The technology has gained significant traction due to its ability to provide a more energy-efficient and cost-effective alternative to traditional infrared sources.

How LED Infrared Works

LED infrared technology operates on the principle of semiconductors. When an electric current passes through a semiconductor material, it emits infrared radiation. The semiconductor material used in LED infrared devices is typically made of gallium arsenide (GaAs) or indium phosphide (InP), which are capable of emitting infrared light at specific wavelengths. The process involves the injection of electrons and holes into the semiconductor material, which then recombine, releasing energy in the form of infrared light. The wavelength of the emitted light can be controlled by altering the composition of the semiconductor material, making LED infrared suitable for a wide range of applications.
