Infrared Emitter LED: Innovate Your Projects with Cutting-Edge Technology

With the rapid development of technology, infrared emitter LED has become an indispensable component in various fields. As a type of light-emitting diode (LED), it emits infrared light and has been widely used in remote controls, security systems, and medical devices. This article will introduce the infrared emitter LED industry, including its working principle, types, applications, and market trends.

Working Principle of Infrared Emitter LED

The infrared emitter LED is a semiconductor device that emits infrared light when an electric current passes through it. It consists of a p-n junction, where the p-type semiconductor has an excess of holes, and the n-type semiconductor has an excess of electrons. When an electric current is applied, electrons from the n-type region are attracted to the holes in the p-type region, and as they move towards the junction, they release energy in the form of photons. These photons have longer wavelengths than visible light, which is why they are in the infrared spectrum.

Types of Infrared Emitter LED

There are several types of infrared emitter LED, each with its own characteristics and applications. The following are some common types:

• AlInGaP infrared emitter LED: This type of LED has a longer wavelength and is suitable for long-distance transmission and receiving.
• GaAs infrared emitter LED: It has a shorter wavelength and is used in short-distance communication and remote control applications.
• InGaAs infrared emitter LED: This type of LED has a high photoelectric conversion efficiency and is used in high-speed optical communication and photoelectric detection.
