Revolutionizing Connectivity: The Power of Infrared Emitter LED Technology

Infrared emitter LED, or infrared emitting diode, is a type of semiconductor device that emits infrared radiation when an electric current passes through it. It has been widely used in various fields such as consumer electronics, automotive, medical, and industrial applications. This article will provide an in-depth introduction to the infrared emitter LED industry, covering its history, working principle, applications, market trends, and future development prospects.

History of Infrared Emitter LED

The infrared emitter LED has a long history, dating back to the early 20th century. In 1900, British physicist Lord Kelvin proposed the concept of infrared radiation, and in 1905, Albert Einstein proposed the photoelectric effect, which laid the theoretical foundation for the development of infrared emitter LED. In the 1960s, with the rapid development of semiconductor technology, the infrared emitter LED was born, and its application field has been continuously expanded.

Working Principle of Infrared Emitter LED

The working principle of the infrared emitter LED is based on the photoelectric effect. When an electric current passes through the semiconductor material, the electrons in the material are excited and move to the conduction band, releasing energy in the form of photons. These photons have a wavelength of 700 nm to 1 mm, which is in the infrared region of the electromagnetic spectrum.

The infrared emitter LED has two main types: one is the PIN-type infrared emitter LED, which has a high forward voltage and a high power output; the other is the avalanche-type infrared emitter LED, which has a lower forward voltage and a lower power output. The choice of the type depends on the specific application requirements.
