Introduction to IR LED Chips
What are IR LED Chips?
IR LED chips, or Infrared Light Emitting Diodes, are a type of semiconductor device that emits infrared light when an electric current is applied. They are widely used in various applications, such as remote controls, security systems, and medical devices. In recent years, the demand for IR LED chips has been increasing due to their compact size, low power consumption, and high efficiency.
Working Principle of IR LED Chips
The working principle of IR LED chips is based on the photoelectric effect. When an electric current passes through the semiconductor material, it generates heat, which excites the electrons in the material. As the electrons return to their original state, they release energy in the form of infrared light. The color of the light emitted by IR LED chips is usually invisible to the human eye, as it falls within the infrared spectrum.
