Infrared LED light, also known as infrared LED, is a type of light-emitting diode that emits light in the infrared spectrum. Unlike visible light, infrared light is not visible to the human eye but can be detected by special sensors and devices. This technology has found wide applications in various industries, from consumer electronics to industrial automation. This article aims to provide an in-depth introduction to the infrared LED light industry, covering its history, technology, applications, and future prospects.
History of Infrared LED Light Technology
The development of infrared LED technology dates back to the early 20th century. In 1900, German physicist Heinrich Hertz discovered the photoelectric effect, which laid the foundation for the development of light-emitting diodes. In the 1960s, infrared LEDs were first developed and used in simple applications such as remote controls. Over the years, with the continuous advancement of semiconductor technology, infrared LED performance has been significantly improved, and its applications have expanded to various fields.
Technology of Infrared LED Light
Infrared LED light is produced by a semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). When an electric current is applied to the semiconductor material, electrons and holes recombine, releasing energy in the form of photons. The wavelength of these photons determines the color of the light, with infrared LEDs emitting light at wavelengths between 700 and 3000 nanometers.
The key factors affecting the performance of infrared LED lights include the material, structure, and driving current. High-quality infrared LEDs require high-purity semiconductor materials and precise control of the manufacturing process. The structure of the LED also plays a crucial role in determining its emission characteristics, such as the emission angle and intensity. The driving current affects the brightness and lifespan of the LED.
