Introduction to High Power IR LED 940nm

High power IR LED 940nm, also known as infrared LED, is a type of light-emitting diode that emits infrared radiation at a wavelength of 940nm. It is widely used in various applications due to its excellent performance in terms of brightness, efficiency, and wavelength stability. The high power IR LED 940nm is different from the common visible light LED, as it emits infrared light that is not visible to the human eye.

Working Principle of High Power IR LED 940nm

The working principle of high power IR LED 940nm is based on the photoelectric effect. When an electric current passes through the semiconductor material, it generates heat, which causes the electrons to move from the valence band to the conduction band. As the electrons move to the conduction band, they recombine with the holes left behind in the valence band, releasing energy in the form of infrared light. The longer the wavelength, the lower the energy and the less visible the light becomes.
