This article will introduce the basic concepts, working principles, types, and applications of high power infrared transmitter diodes, hoping to help readers understand this high-tech product better.
Basic Concepts of High Power Infrared Transmitter Diode
High power infrared transmitter diode is a semiconductor device that converts electrical energy into infrared light energy. It is mainly composed of a p-n junction, a mirror, and a semiconductor material. When the diode is forward biased, the p-n junction will be excited, and the electrons and holes will recombine, releasing energy in the form of infrared light.
Working Principle of High Power Infrared Transmitter Diode
The working principle of high power infrared transmitter diode is based on the principle of p-n junction. When the diode is forward biased, the p-n junction will be excited, and the electrons and holes will recombine, releasing energy in the form of infrared light. The output power of the diode is mainly determined by the material, structure, and design of the diode.
Types of High Power Infrared Transmitter Diodes
High power infrared transmitter diodes can be divided into several types according to their material, structure, and output characteristics.
