Introduction to Infrared Emitter Tube LED

What is an Infrared Emitter Tube LED?

An infrared emitter tube LED, also known as an infrared diode, is a type of light-emitting diode (LED) that emits infrared light. It is widely used in various applications, including remote controls, surveillance cameras, medical devices, and automotive systems. Unlike visible light LEDs, infrared emitter tube LEDs emit light in the infrared spectrum, which is not visible to the human eye. This makes them ideal for applications where invisible light is required for communication or sensing purposes.

Working Principle of Infrared Emitter Tube LED

The working principle of an infrared emitter tube LED is based on the photoelectric effect. When an electric current passes through the diode, it excites the electrons in the semiconductor material, causing them to move to a higher energy level. As these electrons return to their original state, they release energy in the form of photons. In the case of an infrared emitter tube LED, these photons fall within the infrared spectrum, resulting in the emission of infrared light.
