5W IR LED, also known as the 5W infrared light-emitting diode, is a type of semiconductor device that emits infrared light. It has become increasingly popular in various applications due to its high brightness, low power consumption, and long lifespan. This article will provide an in-depth introduction to the 5W IR LED industry, covering its history, technology, applications, market trends, and future prospects.

History of 5W IR LED

The development of infrared light-emitting diodes dates back to the 1960s when the first infrared LED was invented. However, it was not until the 1980s that the 5W IR LED was born. With the continuous improvement of technology, the brightness and lifespan of 5W IR LED have been significantly improved, making it more suitable for various applications.

Technology of 5W IR LED

The 5W IR LED is a semiconductor device that emits infrared light when an electric current is applied. It consists of a p-n junction, which is formed by diffusing a p-type semiconductor material onto an n-type semiconductor material. When the p-n junction is forward biased, electrons and holes are injected into the junction, and then recombine to emit infrared light.

5W IR LED has several advantages in terms of technology. Firstly, it has a high brightness, which can reach up to 100,000 mcd. Secondly, it has a low power consumption, which can save energy and reduce costs. Thirdly, it has a long lifespan, which can reach up to 50,000 hours. Finally, it has a wide application range, which can be used in various fields such as security, medical, and automotive.
