Introduction to High Output IR LED

High output IR LED is a type of semiconductor device that emits infrared light when an electric current passes through it. Unlike traditional LEDs, which emit visible light, high output IR LEDs emit light in the infrared spectrum, which is not visible to the human eye. These LEDs are widely used in applications that require long-range detection, communication, and sensing.

How High Output IR LED Works

The working principle of high output IR LED is based on the semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). When an electric current is applied, the electrons and holes recombine within the semiconductor, releasing energy in the form of infrared light. The intensity of the light output is determined by the forward voltage and the current flowing through the LED.
