IR black LED, or Infrared Black LED, is a type of light-emitting diode that emits infrared light. It is widely used in various fields such as security, medical, automotive, and consumer electronics. This article will introduce the IR black LED industry, including its working principle, application fields, market trends, and future development prospects.

Working Principle of IR Black LED

IR black LED is a semiconductor device that emits infrared light when an electric current passes through it. The material used in the IR black LED is usually gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). When the electric current passes through the semiconductor material, the electrons and holes in the material recombine, releasing energy in the form of infrared light. The wavelength of the emitted light is typically between 780nm and 950nm, which is in the infrared spectrum.
