Introduction to SMD IR LED

SMD IR LED is a type of semiconductor device that emits infrared light when an electric current is applied. Unlike traditional LED technology, which emits visible light, SMD IR LED operates in the infrared spectrum. This makes it ideal for applications where invisible light is required, such as remote controls, security systems, and communication devices.

How SMD IR LED Works

The working principle of SMD IR LED is based on the photoelectric effect. When an electric current passes through the semiconductor material, it generates heat, which excites the electrons within the material. These excited electrons then recombine with the holes in the material, releasing energy in the form of infrared light. The wavelength of the emitted light depends on the composition of the semiconductor material.
