Infrared lamp bead, also known as infrared emitting diode (IRED), is a semiconductor device that emits infrared radiation when an electric current passes through it. It is widely used in various applications, including consumer electronics, automotive, medical, and industrial sectors. This article provides an in-depth introduction to the infrared lamp bead industry, covering its history, working principle, applications, market trends, and future prospects.

History of Infrared Lamp Bead

The concept of infrared lamp bead dates back to the early 20th century. In 1906, British scientist William Henry Beverly became the first person to patent an infrared emitting diode. However, it was not until the 1960s that infrared lamp beads started to gain attention in the industry. With the advancement of semiconductor technology, infrared lamp beads became more efficient and reliable, leading to their widespread use in various applications.

Working Principle of Infrared Lamp Bead

Infrared lamp beads work on the principle of the semiconductor diode. When an electric current passes through the diode, it generates heat, which excites the electrons in the semiconductor material. These excited electrons then recombine with the holes in the material, releasing energy in the form of infrared radiation. The color of the emitted light depends on the semiconductor material used, with different materials emitting different wavelengths of infrared radiation.
