Introduction to Bright IR LED Industry

1. Definition and Overview of Bright IR LED

Bright IR LED, short for Infrared Light Emitting Diode, is a type of light-emitting diode that emits infrared light with high brightness. It is widely used in various fields such as security monitoring, automotive, medical, and industrial applications. Compared with traditional infrared light sources, bright IR LED has the advantages of high brightness, long lifespan, low power consumption, and small size, making it an ideal choice for modern applications.

2. Development History of Bright IR LED

The development of bright IR LED technology can be traced back to the 1960s. At that time, the research on infrared light-emitting diodes was just beginning. In the 1970s, with the continuous improvement of semiconductor technology, the brightness of infrared light-emitting diodes was gradually improved. In the 1980s, the development of bright IR LED technology entered a new stage, and its application fields were also expanding. In the 21st century, with the rapid development of the semiconductor industry, the brightness, lifespan, and stability of bright IR LED have been significantly improved, and its market demand has continued to increase.

3. Working Principle of Bright IR LED

The working principle of bright IR LED is based on the semiconductor physics. When the forward bias voltage is applied to the PN junction of the semiconductor material, the electrons and holes are injected into the depletion region, and then recombine. During the recombination process, part of the energy is released in the form of infrared light. The brightness of the light is determined by the energy difference between the electrons and holes, and the longer the energy difference, the higher the brightness of the light.

4. Types of Bright IR LED

Bright IR LED can be divided into several types according to the materials and structures. The main types include:
