LED IR, or Light Emitting Diode Infrared, has become a crucial technology in various industries due to its unique properties and applications. This article aims to provide an in-depth introduction to the LED IR industry, covering its history, technology, applications, market trends, and future prospects.

History of LED IR Technology

LED IR technology has a long history, dating back to the early 20th century. The first infrared (IR) diode was invented by Oleg Losev in 1907, and it was based on the semiconductor material Selenium. However, it was not until the 1960s that LED IR technology began to gain attention due to the development of gallium arsenide (GaAs) and gallium phosphide (GaP) as semiconductor materials. In the 1970s, LED IR devices started to be commercialized, and their applications expanded rapidly in various fields.

Technology of LED IR

LED IR technology is based on the principle of emitting infrared light through a semiconductor material. When an electric current passes through the semiconductor material, it emits infrared light. The key components of an LED IR device include the semiconductor material, a p-n junction, and an optical lens.

The semiconductor material is the core of an LED IR device. Different semiconductor materials can emit different wavelengths of infrared light. For example, GaAs emits infrared light with a wavelength of 830 nm, while GaP emits infrared light with a wavelength of 940 nm. The p-n junction is formed by combining a p-type semiconductor material with an n-type semiconductor material, which creates a voltage difference that allows the emission of infrared light.

The optical lens is used to focus the emitted infrared light, which can improve the detection distance and accuracy of the LED IR device. The design and quality of the optical lens can significantly affect the performance of the LED IR device.
