High power infrared transmitter diode, as a key component in the field of infrared technology, plays a crucial role in various applications such as remote control, communication, and sensing. This article aims to provide an in-depth introduction to the industry of high power infrared transmitter diodes, covering their working principles, types, applications, and future development trends.
Working Principles of High Power Infrared Transmitter Diode
High power infrared transmitter diode is a semiconductor device that emits infrared light through the process of electroluminescence. When a forward voltage is applied to the diode, electrons and holes are injected into the active layer, and through the recombination of electrons and holes, infrared light is emitted. The output power of the diode is determined by the material, structure, and manufacturing process.
The working principle of high power infrared transmitter diode can be described in the following steps:
1. Forward voltage is applied to the diode, causing electrons and holes to be injected into the active layer.
2. Electrons and holes recombine in the active layer, releasing energy in the form of infrared light.
3. The infrared light is emitted from the diode, and its intensity and power are determined by the material and structure of the diode.
