Introduction to Infrared Emitter Tube LED

What is an Infrared Emitter Tube LED?

The infrared emitter tube LED, or Infrared Emitting Diode (IRED), is a type of semiconductor device that emits infrared light when an electric current is applied to it. Unlike visible light LEDs, which emit light in the visible spectrum, infrared LEDs emit light in the infrared spectrum, which is not visible to the human eye. These devices are widely used in various applications due to their compact size, low power consumption, and efficient operation.

Working Principle of Infrared Emitter Tube LED

The working principle of an infrared emitter tube LED is based on the photoelectric effect. When a forward bias voltage is applied to the LED, electrons are injected from the n-type semiconductor into the p-type semiconductor. The collision between these electrons and holes (positive charge carriers) releases energy in the form of photons. Since the energy levels of the electrons in the semiconductor material are higher than those in the infrared region, the photons emitted are in the infrared spectrum. The key to producing infrared light lies in the semiconductor material used in the LED. Common materials include gallium arsenide (GaAs), gallium phosphide (GaP), and aluminum gallium arsenide (AlGaAs). These materials have energy band gaps that correspond to the infrared region, allowing them to emit infrared light efficiently.
