Strong IR LED, or Infrared Light Emitting Diode, has become an essential component in various industries due to its unique features and wide applications. This article aims to provide an in-depth introduction to the industry of strong IR LED, covering its definition, working principle, applications, and future development trends.

Definition of Strong IR LED

Strong IR LED is a type of semiconductor device that emits infrared light with a wavelength between 780nm and 3000nm. It is widely used in various fields, such as remote control, communication, security, and medical equipment. Compared with traditional IR LED, strong IR LED has higher power, longer transmission distance, and better anti-interference ability.

Working Principle of Strong IR LED

The working principle of strong IR LED is based on the photoelectric effect. When a forward voltage is applied to the PN junction of the semiconductor material, electrons and holes are generated. As the electrons move to the N region, they collide with the atoms and emit infrared light. The strength of the infrared light is determined by the material, structure, and forward voltage of the LED.
