Introduction to IR LED Industry

What is an IR LED?

An IR LED, or Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current is applied to it. Unlike visible light, infrared light is not visible to the human eye. It is used in a wide range of applications, from consumer electronics to industrial automation, due to its ability to transmit information wirelessly and its non-intrusive nature.

How Does an IR LED Work?

An IR LED works on the principle of the PN junction. When an electric current is applied to the PN junction, electrons and holes recombine, releasing energy in the form of photons. These photons are in the infrared spectrum, which is not visible to the human eye. The intensity of the light emitted by an IR LED depends on the material used in the diode, the current flowing through it, and the temperature.

Applications of IR LEDs

IR LEDs have a wide range of applications due to their unique properties. Some of the most common applications include: -

Remote controls: IR LEDs are used in remote controls for TVs, air conditioners, and other electronic devices. They emit infrared light that is received by a sensor in the device, allowing the user to control it from a distance.

-

Security systems: IR LEDs are used in security systems to detect motion. When an object moves in front of the LED, it emits a signal that is detected by a sensor, triggering an alarm.

-
