This article will introduce the industry of infrared LED patch, including its basic principle, application fields, market prospects, and future development trends.

Basic Principle of Infrared LED Patch

The infrared LED patch is a kind of semiconductor device, which uses the principle of photoelectric effect. When the forward bias voltage is applied to the PN junction of the semiconductor material, the electrons and holes are injected into the conduction band and valence band, respectively. When the electrons and holes recombine, a part of the energy is released in the form of light, and the light emitted is in the infrared spectrum. The infrared LED patch can be used to emit infrared light with a certain wavelength, and the light intensity and wavelength can be adjusted by adjusting the material and structure of the semiconductor.
