Now, it is widely used in various fields, such as consumer electronics, automotive, medical, and industrial applications.

Working Principle of Infrared Emitter Tube LED

The working principle of the infrared emitter tube LED is based on the photoelectric effect of semiconductor materials. When an electric current passes through the semiconductor material, electrons and holes are generated, and the recombination of electrons and holes will release energy in the form of photons. The wavelength of the emitted photons is determined by the energy band gap of the semiconductor material. Infrared emitter tube LED is a semiconductor material with a relatively large energy band gap, so it emits infrared light. The infrared emitter tube LED has a simple structure, mainly including a semiconductor chip, a lead frame, and a lens. The semiconductor chip is the core part of the infrared emitter tube LED, which emits infrared light. The lead frame is used to connect the semiconductor chip to the external circuit, and the lens is used to focus the emitted infrared light.
