With the rapid development of technology, infrared emitter LED has become an essential component in various applications. As a type of light-emitting diode (LED), infrared emitter LED emits infrared radiation, which is invisible to the human eye. This article will provide an in-depth introduction to the infrared emitter LED industry, covering its basic principles, applications, market trends, and future prospects.
Basic Principles of Infrared Emitter LED
Infrared emitter LED is a semiconductor device that emits infrared light. It is composed of a p-n junction, where electrons and holes recombine to produce photons. The process of recombination releases energy in the form of infrared radiation. The color of the emitted light depends on the bandgap of the semiconductor material used. Generally, infrared emitter LED emits light in the range of 780 to 3000 nm.
The structure of an infrared emitter LED includes a p-type semiconductor layer, an n-type semiconductor layer, and a metal contact layer. The p-n junction is formed between the p-type and n-type layers. When a forward bias is applied to the LED, electrons from the n-type layer move to the p-type layer, and holes from the p-type layer move to the n-type layer. As a result, electrons and holes recombine at the p-n junction, emitting infrared radiation.
