Introduction to High Power Infrared Transmitter Diode

A high power infrared transmitter diode is a semiconductor device that emits infrared radiation at a high power level. It is commonly used in applications that require long-distance communication or precise positioning. The working principle of a high power infrared transmitter diode is based on the photoelectric effect, where an electrical current is generated when the diode is exposed to infrared radiation.

Working Principle

The working principle of a high power infrared transmitter diode is based on the photoelectric effect. When an infrared light source, such as a laser or LED, is incident on the diode, the photons are absorbed by the semiconductor material, which then generates an electrical current. The intensity of the current is directly proportional to the intensity of the incident light. This process is called photoelectric conversion.
