Introduction to High Power IR Emitter

A high power IR emitter is a device that emits infrared radiation with high intensity. It is primarily used for transmitting signals, detecting objects, and generating heat. The device operates based on the principle of semiconductor physics, where electrons are excited to higher energy levels and then recombine, emitting infrared radiation in the process.

Working Principle of High Power IR Emitter

The working principle of a high power IR emitter is based on the P-N junction of a semiconductor material. When a forward bias voltage is applied to the P-N junction, electrons from the N-type material migrate to the P-type material, and holes from the P-type material migrate to the N-type material. This movement of charge carriers creates an electric current, which generates heat and emits infrared radiation.
