UVC LEDs, or ultraviolet light-emitting diodes, have become a revolutionary technology in the field of lighting and disinfection. These diodes emit light at a specific wavelength of 200 to 400 nanometers, which falls within the ultraviolet (UV) spectrum. This unique property makes UVC LEDs highly effective in sterilization, purification, and various other applications. In this article, we will explore the industry of UVC LEDs, including their working principle, applications, market trends, and future prospects.

Working Principle of UVC LEDs

UVC LEDs work on the principle of semiconductor physics. When an electric current is applied to a semiconductor material, electrons are excited and move to higher energy levels. When these electrons return to their original energy levels, they release energy in the form of light. In the case of UVC LEDs, the semiconductor material is specifically designed to emit light at the desired UV-C wavelength. The key to achieving this is the use of specific semiconductor materials, such as gallium nitride (GaN), silicon carbide (SiC), and zinc selenide (ZnSe). These materials have a direct bandgap, which means they can efficiently convert electrical energy into UV light. The bandgap of these materials is carefully tuned to emit light at the desired UV-C wavelength.

Applications of UVC LEDs

The applications of UVC LEDs are diverse and growing rapidly. Some of the key areas where UVC LEDs are being used include: 1.
