This article aims to provide an in-depth introduction to high power IR LED, covering its basic principles, applications, market trends, and future prospects.

Basic Principles of High Power IR LED

High Power IR LED is a semiconductor device that emits infrared light when an electric current is applied. It consists of a p-n junction, where the p-type and n-type semiconductors are doped with impurities to create a forward bias. When the current flows through the p-n junction, electrons and holes recombine, releasing energy in the form of infrared light. The key parameters that determine the performance of a high power IR LED include its forward voltage, forward current, luminous intensity, and efficiency. The forward voltage is the voltage required to forward bias the LED, while the forward current is the current that flows through the LED when it is forward biased. Luminous intensity refers to the amount of light emitted by the LED, and efficiency is the ratio of the light output to the electrical power input.
