Strong IR LED, or Infrared Light Emitting Diode, has become an integral part of various industries due to its ability to emit infrared light with high intensity. This article aims to provide a comprehensive introduction to the industry of strong IR LED, covering its technology, applications, market trends, and future prospects.

Introduction to Strong IR LED Technology

Strong IR LED technology is based on the principle of semiconductor physics. When a forward bias is applied to a PN junction, electrons and holes recombine, releasing energy in the form of light. In the case of IR LEDs, the emitted light falls within the infrared spectrum, which is invisible to the human eye. The term "strong" refers to the high intensity of the emitted light, making it suitable for long-distance communication and detection applications.

Working Principle of Strong IR LED

The working principle of a strong IR LED is similar to that of a regular LED. It consists of a semiconductor material, typically Gallium Arsenide (GaAs) or Aluminum Gallium Arsenide (AlGaAs), which emits infrared light when an electric current passes through it. The structure of the LED includes a p-type layer, an n-type layer, and a window layer to facilitate the emission of light. The wavelength of the emitted light is determined by the composition and thickness of the semiconductor layers.
