Definition and Classification of High Power Infrared LED

High power infrared LED refers to a semiconductor device that emits infrared light with a power greater than 1W. According to the wavelength, high power infrared LED can be divided into near-infrared LED, mid-infrared LED, and far-infrared LED. Among them, near-infrared LED has a wavelength range of 780nm-3000nm, mid-infrared LED has a wavelength range of 3000nm-5000nm, and far-infrared LED has a wavelength range of 5000nm-10000nm.

Working Principle of High Power Infrared LED

The working principle of high power infrared LED is based on the semiconductor photoelectric effect. When the forward voltage is applied to the LED, electrons and holes are injected into the active layer of the LED. Through the recombination of electrons and holes, photons are emitted, and infrared light is generated. The intensity of the emitted light is determined by the injection current, the material quality, and the structure of the LED.
