This article aims to provide an in-depth introduction to the 5mm IR LED, covering its basic principles, applications, and market trends.

Basic Principles of 5mm IR LED

The 5mm IR LED is a semiconductor device that emits infrared light when an electric current is applied. It consists of a p-n junction, where electrons and holes recombine to produce photons. The process of emitting light is called electroluminescence. The emitted light has a wavelength range of 700nm to 1000nm, which is beyond the visible spectrum for human eyes.

5mm IR LED is typically made of gallium arsenide (GaAs), gallium phosphide (GaP), or other semiconductor materials. These materials have high electron mobility and can efficiently convert electrical energy into light. The size of the LED is determined by the semiconductor wafer, which is usually 5mm in diameter. This compact size makes the 5mm IR LED suitable for various applications with limited space.
