IR emitter diode, also known as infrared emitting diode, is a semiconductor device that emits infrared light when an electric current passes through it. As a key component in the infrared detection and communication field, it has been widely used in various applications such as remote control, infrared communication, and infrared sensing. This article will introduce the industry of IR emitter diodes, including its development history, working principle, application fields, and market prospects.
Development History of IR Emitter Diodes
The development of IR emitter diodes can be traced back to the early 20th century. In 1908, a German physicist named Heinrich Hertz discovered that when an electric current passes through a vacuum tube, it can emit electromagnetic waves. This discovery laid the foundation for the development of IR emitter diodes. In the 1950s, with the development of semiconductor technology, the first IR emitter diode was successfully developed. Since then, the technology of IR emitter diodes has been continuously improved and developed, and it has been widely used in various fields.
Working Principle of IR Emitter Diodes
IR emitter diodes are based on the principle of semiconductor physics. When an electric current passes through the diode, the electrons and holes in the semiconductor material are recombined, releasing energy in the form of infrared light. The intensity and wavelength of the emitted light are determined by the material composition and structure of the diode. Generally, IR emitter diodes have a short wavelength and high intensity, which is suitable for long-distance transmission and high-speed communication.
