Introduction to Infrared Transmitting Tube LED

What is an Infrared Transmitting Tube LED?

An infrared transmitting tube LED, also known as an infrared LED, is a type of light-emitting diode that emits infrared radiation. Unlike visible light, infrared radiation is not visible to the human eye. However, it is widely used in various applications due to its unique properties. Infrared transmitting tube LEDs are commonly used in remote controls, security systems, medical devices, and communication systems.

How Does an Infrared Transmitting Tube LED Work?

An infrared transmitting tube LED works on the principle of semiconductor physics. It consists of a semiconductor material, typically gallium arsenide (GaAs), which emits infrared radiation when an electric current passes through it. The semiconductor material is sandwiched between two electrodes, and when a voltage is applied across the electrodes, electrons and holes recombine, releasing energy in the form of infrared radiation. The key components of an infrared transmitting tube LED include the semiconductor material, the p-n junction, the lead frame, and the encapsulation. The semiconductor material is the core of the LED, where the infrared radiation is generated. The p-n junction is formed at the interface between the p-type and n-type semiconductor materials, where the recombination of electrons and holes occurs. The lead frame provides electrical connections to the semiconductor material, and the encapsulation protects the LED from external factors such as moisture and dust.
