Introduction to Infrared LED Chip Industry

Understanding Infrared LED Chip

The infrared LED chip, a crucial component in the realm of optoelectronics, plays a pivotal role in a variety of applications, from consumer electronics to industrial automation. An infrared LED chip is a semiconductor device that emits infrared light when an electrical current is applied to it. Unlike visible light, infrared light is not visible to the human eye, but it is detectable by sensors and other electronic devices. The efficiency, brightness, and lifespan of an infrared LED chip are key factors that determine its performance and suitability for different applications.

How Infrared LED Chips Work

Infrared LED chips operate on the principle of the electroluminescence phenomenon. When a current is passed through the semiconductor material, it excites the electrons, causing them to jump to a higher energy level. As these electrons return to their original state, they release energy in the form of photons. In the case of infrared LED chips, these photons fall within the infrared spectrum, which is just beyond the visible light range. The structure of an infrared LED chip typically includes a p-n junction, where the p-type and n-type semiconductor materials meet. The p-type material has an excess of positively charged carriers (holes), while the n-type material has an excess of negatively charged carriers (electrons). When a forward bias voltage is applied across the p-n junction, electrons from the n-type material combine with holes from the p-type material, releasing energy in the form of infrared light.
