This article will provide an in-depth introduction to the industry of infrared LED high power, covering its history, technology, market status, and future development trends.

History of Infrared LED High Power

The history of infrared LED high power can be traced back to the 1960s when the first infrared LED was developed. At that time, the technology was still in its infancy, and the power of the infrared LED was very low. With the continuous development of semiconductor technology, the power of infrared LED has been significantly improved. In the 1990s, high-power infrared LED technology began to emerge, and its application has been rapidly expanded.

Technology of Infrared LED High Power

Infrared LED high power technology is mainly based on the development of semiconductor materials and device structure. The key to high-power infrared LED technology lies in the optimization of the device structure and the improvement of the material properties. The following are some of the key technologies: 1. Material selection: High-power infrared LED usually adopts gallium nitride (GaN) as the core material. Compared with other semiconductor materials, GaN has higher thermal conductivity, better electrical properties, and lower thermal expansion coefficient, which is beneficial to the improvement of the device performance. 2. Device structure: High-power infrared LED usually adopts the vertical structure. This structure can effectively improve the electrical field strength and reduce the loss of the device. At the same time, the vertical structure can also facilitate the heat dissipation of the device. 3. Heat dissipation: High-power infrared LED has a high power density, so heat dissipation is very important. The commonly used heat dissipation methods include heat sink, heat pipe, and heat conduction plate. Among them, the heat sink has the advantages of low cost and easy to use.
