Invisible IR LED, also known as invisible infrared LED, is a type of light-emitting diode that emits infrared light at a wavelength outside the visible spectrum. Due to its unique characteristics, invisible IR LED has been widely used in various fields, such as consumer electronics, automotive, medical, and security. This article aims to provide an in-depth introduction to the invisible IR LED industry, covering its history, technology, applications, and market trends.

History of Invisible IR LED

The concept of invisible IR LED can be traced back to the early 20th century when infrared technology was first developed. However, it was not until the 1970s that the first infrared LED was successfully developed by Japanese researchers. Since then, the technology has undergone continuous innovation and has been widely used in various fields. The rapid development of invisible IR LED technology has been driven by the increasing demand for high-performance, energy-efficient, and cost-effective infrared light sources.

Technology of Invisible IR LED

Invisible IR LED technology is based on the principle of semiconductor physics. When a forward voltage is applied to the semiconductor material, electrons and holes are generated, which recombine and emit photons. The wavelength of the emitted photons is determined by the energy bandgap of the semiconductor material. In the case of invisible IR LED, the semiconductor material used is typically gallium arsenide (GaAs) or gallium nitride (GaN), which emits infrared light at a wavelength of 850nm to 950nm. The main advantages of invisible IR LED technology include: 1. High efficiency: The energy conversion efficiency of invisible IR LED is as high as 30%, which is much higher than that of traditional infrared light sources. 2. Long lifespan: The lifespan of invisible IR LED is up to 100,000 hours, which is significantly longer than that of traditional infrared light sources. 3. Low power consumption: The power consumption of invisible IR LED is very low, which is conducive to energy saving and environmental protection. 4. Miniaturization: The size of invisible IR LED is very small, which can be easily integrated into various electronic devices.
