LED infrared, also known as infrared LED, has become an essential component in various industries due to its unique advantages and wide range of applications. This article will provide an in-depth introduction to the LED infrared industry, covering its history, technology, applications, market trends, and future prospects.

History of LED Infrared Technology

The development of LED infrared technology can be traced back to the early 20th century when infrared radiation was first discovered. However, it was not until the 1960s that the first infrared LED was successfully developed. Since then, with the continuous advancement of semiconductor technology, the performance of LED infrared devices has been significantly improved, and their applications have been expanding.

Technology of LED Infrared

LED infrared technology is based on the principle of semiconductor photoelectric conversion. When an electric current passes through a semiconductor material, electrons and holes are generated, and when they recombine, they emit photons. The wavelength of the emitted photons is determined by the energy band gap of the semiconductor material. Infrared LEDs are made of materials with a larger energy band gap, such as gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs), which emit infrared light.

LED infrared technology mainly includes the following aspects:

• Material technology: The selection of semiconductor materials is crucial for the performance of LED infrared devices. Currently, GaAs and AlGaAs are the most commonly used materials for infrared LEDs.
• Optical design: The optical design of LED infrared devices is to optimize the light-emitting efficiency and directivity. This includes the design of the lens, reflector, and encapsulation materials.
• Heat dissipation: Infrared LEDs have a high power density, so heat dissipation is a critical factor affecting their performance. Effective heat dissipation can improve the lifespan and stability of the device.
