Revolutionizing Illumination: The Cutting-Edge Potential of UV Light Emitting Diodes

UV light emitting diode, or UV LED, is a type of semiconductor device that emits ultraviolet light when an electric current is applied. With the rapid development of technology and the increasing demand for UV applications, UV LED has become a hot topic in the industry. This article will introduce the industry of UV LED, including its working principle, application fields, market prospects, and challenges.

Working Principle of UV LED

UV LED works on the principle of semiconductor physics. When an electric current is applied to the PN junction of the semiconductor material, electrons and holes are generated. These electrons and holes recombine and release energy in the form of ultraviolet light. The wavelength of the emitted light is determined by the energy gap of the semiconductor material.
