5mm IR LED, also known as Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current is applied. Due to its compact size, low power consumption, and high efficiency, it has been widely used in various fields such as consumer electronics, automotive, and industrial applications. This article will introduce the 5mm IR LED industry, including its working principle, applications, market trends, and future development prospects.

Working Principle of 5mm IR LED

The 5mm IR LED is made of a semiconductor material, typically gallium arsenide (GaAs) or gallium phosphide (GaP), which has a direct bandgap. When an electric current passes through the diode, the electrons and holes recombine in the depletion region, releasing energy in the form of infrared light. The size of the infrared light emitted depends on the bandgap of the semiconductor material used. The 5mm IR LED typically emits light in the near-infrared spectrum, which is not visible to the human eye.
