Security IR LED, or Infrared Light Emitting Diode, has become an essential component in modern security systems. With the rapid development of technology, security IR LED has been widely used in various fields, such as home, commercial, and industrial applications. This article will provide an in-depth introduction to security IR LED, covering its working principle, advantages, applications, and future trends.

Introduction to Security IR LED

Security IR LED is a type of semiconductor device that emits infrared light. It is used in security systems to detect and monitor unauthorized access. The emitted infrared light is invisible to the naked eye, making it an ideal choice for security applications. Security IR LED is available in different wavelengths, such as 850nm, 940nm, and 980nm, which can be selected based on the specific application requirements.

Working Principle of Security IR LED

The working principle of security IR LED is based on the photoelectric effect. When an electric current passes through the semiconductor material, it emits infrared light. The emitted light is then detected by a photoelectric sensor, which converts the light signal into an electrical signal. The electrical signal is then processed by the control unit to determine whether there is an unauthorized access or not.
