This article will introduce the infrared emitter LED industry, including its working principle, application, market prospects, and challenges.

Introduction to Infrared Emitter LED

Infrared emitter LED, also known as infrared diode, is a semiconductor device that emits infrared light when an electric current passes through it. It is mainly composed of a p-n junction, which is formed by the diffusion of p-type and n-type materials. When the forward voltage is applied to the p-n junction, electrons and holes are generated, and the recombination of electrons and holes produces infrared light. The main characteristics of infrared emitter LED are as follows: 1. High efficiency: The conversion efficiency of infrared emitter LED is high, which can reach more than 50%. 2. Energy-saving: Infrared emitter LED has low power consumption, which is conducive to energy saving and environmental protection. 3. Long lifespan: The lifespan of infrared emitter LED is long, which can reach tens of thousands of hours. 4. Small size and light weight: Infrared emitter LED has a small size and light weight, which is convenient for installation and use.

Working Principle of Infrared Emitter LED

The working principle of infrared emitter LED is based on the p-n junction. When the forward voltage is applied to the p-n junction, electrons and holes are generated. The electrons move to the n-side, and the holes move to the p-side. As the electrons move to the n-side, they collide with the atoms and release energy in the form of infrared light. The same process occurs when the holes move to the p-side. The wavelength of the emitted infrared light is determined by the energy gap of the semiconductor material. The shorter the energy gap, the shorter the wavelength, and the higher the frequency. Generally, the wavelength of infrared emitter LED is between 780nm and 950nm.
