Bright IR LED, short for Infrared Light Emitting Diode, has become an essential component in various industries due to its excellent performance and wide range of applications. This article aims to provide an in-depth introduction to the bright IR LED industry, covering its definition, working principle, applications, market trends, and future prospects.

Definition and Working Principle of Bright IR LED

Bright IR LED is a type of semiconductor device that emits infrared light when an electric current passes through it. It is composed of a p-n junction, which is a semiconductor material with a positive charge (p-type) and a negative charge (n-type). When the electric current is applied, electrons and holes recombine at the junction, releasing energy in the form of infrared light.

Compared with traditional infrared light sources, such as infrared lamps and bulbs, bright IR LEDs have the following advantages:

• High efficiency: The conversion efficiency of bright IR LEDs is up to 30%, which is much higher than that of traditional infrared light sources.
• Small size: Bright IR LEDs can be made into tiny chips, which are easy to integrate into various devices.
• Long lifespan: The lifespan of bright IR LEDs can reach tens of thousands of hours, which is much longer than that of traditional infrared light sources.
• Low power consumption: Bright IR LEDs consume less power, which is beneficial for energy conservation and environmental protection.
