Introduction to Infrared Emitter Tube LED
What is an Infrared Emitter Tube LED?
The infrared emitter tube LED, also known as an infrared diode, is a type of light-emitting diode (LED) that emits infrared radiation. It is widely used in various applications, such as remote controls, security systems, and medical devices. 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.
How Does an Infrared Emitter Tube LED Work?
An infrared emitter tube LED works on the principle of the semiconductor diode. When an electric current is applied to the diode, it generates light by the process of electroluminescence. In the case of an infrared emitter tube LED, the emitted light falls within the infrared spectrum, which ranges from 700 to 3000 nanometers (nm). The specific wavelength of the emitted light depends on the material used in the diode.
The key components of an infrared emitter tube LED include the semiconductor material, a p-n junction, and a lens. The semiconductor material is typically made of gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide (InGaAs). The p-n junction is formed by doping the semiconductor material with impurities to create an electrically charged region. The lens helps to focus the emitted light into a narrow beam.
