Innovative Designs and Advanced Technologies in Infrared Light Emitter Applications

Infrared light emitter, also known as infrared LED, is a crucial component in various applications, including consumer electronics, automotive, industrial, and medical fields. This article aims to provide an in-depth introduction to the infrared light emitter industry, covering its working principles, types, applications, market trends, and future prospects.

Working Principles of Infrared Light Emitter

The infrared light emitter is a device that converts electrical energy into infrared light. It operates based on the principle of semiconductor physics. When an electric current passes through a semiconductor material, electrons and holes are generated. As electrons move towards the cathode, they recombine with holes, releasing energy in the form of photons. These photons have longer wavelengths than visible light, which is why they are called infrared light.

Types of Infrared Light Emitter

There are mainly two types of infrared light emitters: infrared LED and infrared laser.

1. Infrared LED: Infrared LED is a semiconductor device that emits infrared light when an electric current passes through it. It has a longer wavelength than visible light, typically ranging from 700 nm to 3,000 nm. Infrared LEDs are widely used in consumer electronics, automotive, and industrial applications due to their high efficiency, low cost, and compact size.

2. Infrared Laser: Infrared laser is a device that emits infrared light through stimulated emission. It has a shorter wavelength than infrared LED, typically ranging from 700 nm to 1,000 nm. Infrared lasers are used in applications that require higher precision and power, such as medical diagnosis, material processing, and optical communication.
