Infrared transmitter light emitting diode (IR LED) is a crucial component in the field of infrared communication technology. As the name suggests, it is a type of light emitting diode that emits infrared light. This article aims to provide an in-depth introduction to the industry of infrared transmitter light emitting diodes, covering their basic principles, applications, market trends, and future prospects.

Basic Principles of Infrared Transmitter Light Emitting Diode

An infrared transmitter light emitting diode is a semiconductor device that emits infrared light when an electric current passes through it. The basic principle of its operation is based on the forward biasing of a PN junction. When the diode is forward biased, electrons and holes are injected into the depletion region, leading to the recombination of these carriers. During the recombination process, energy is released in the form of photons, which are emitted as infrared light. The infrared light emitted by the IR LED has a wavelength range of approximately 700 to 3000 nanometers. This light is invisible to the human eye, making it suitable for applications where visible light would be undesirable or disruptive. The intensity of the emitted light depends on the forward current, junction temperature, and the quality of the semiconductor material.
