Introduction to Infrared LED Chip Industry

What is an Infrared LED Chip?

An infrared LED chip, also known as an infrared light-emitting diode, is a semiconductor device that emits infrared light when an electric current passes through it. It is widely used in various applications, such as remote controls, surveillance cameras, and wireless communication systems. The infrared LED chip is a key component in these applications, as it provides the necessary infrared light for the system to function properly.

Working Principle of Infrared LED Chip

The working principle of an infrared LED chip is based on the photoelectric effect. When an electric current is applied to the semiconductor material, electrons and holes are generated. When these electrons and holes recombine, they release energy in the form of infrared light. The wavelength of the emitted light is typically between 700 nm and 3000 nm, which falls within the infrared spectrum.
