With its unique characteristics and applications, the black IR LED market has witnessed significant growth over the years. This article aims to provide a comprehensive introduction to the black IR LED industry, covering its history, technology, applications, market trends, and future prospects.

History and Development

The history of black IR LED dates back to the 1960s when infrared technology was first introduced. However, it was not until the 1980s that black IR LED began to gain popularity. The development of black IR LED technology was driven by the increasing demand for infrared devices in various fields. Initially, black IR LED was primarily used in remote controls, but its applications have expanded to include many other areas.

Technology

Black IR LED is a type of LED that emits infrared light. It is made up of a semiconductor material, typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), which emits infrared radiation when an electric current is applied. The black color of the LED is achieved by using a black encapsulant, which absorbs and scatters the emitted light, making it appear black.

The key parameters of black IR LED include wavelength, power, and viewing angle. The wavelength of black IR LED typically ranges from 780nm to 980nm, which is within the invisible infrared spectrum. The power of black IR LED can vary from a few milliwatts to several watts, depending on the application. The viewing angle of black IR LED is an important factor, as it determines the range and direction of the emitted light.
