Revolutionizing Technology: The Future of High Power UV LED Applications

High power UV LED, also known as high power ultraviolet light-emitting diode, has become a hot topic in the industry due to its wide range of applications and significant advantages over traditional UV light sources. This article will introduce the high power UV LED industry, including its basic principles, application fields, market status, and future development trends.

Basic Principles of High Power UV LED

High power UV LED is a semiconductor device that emits ultraviolet light with a wavelength of 10nm to 400nm. It is composed of a p-n junction, and the ultraviolet light is emitted through the semiconductor layer. The working principle is based on the photoelectric effect, where electrons and holes are generated in the semiconductor layer when it is excited by an external electric field. These electrons and holes recombine and emit ultraviolet light.

Compared with traditional UV light sources, high power UV LED has the following advantages:

• High efficiency: The conversion efficiency of high power UV LED can reach 50% to 60%, which is much higher than that of traditional UV light sources.
• Long life: The service life of high power UV LED can reach 10,000 to 50,000 hours, which is much longer than that of traditional UV light sources.
• Small size and light weight: High power UV LED has a small size and light weight, which is more suitable for various applications.
