Working Principles of UV Diode LED

UV Diode LEDs operate based on the principle of electroluminescence, which is the process of light emission when a current is applied across a semiconductor material. When a forward voltage is applied to the diode, electrons and holes recombine at the p-n junction, releasing energy in the form of UV light. The UV spectrum ranges from 10 nm to 400 nm, and UV Diode LEDs typically emit light in the range of 300 nm to 400 nm.

The key components of a UV Diode LED include a semiconductor chip, a phosphor coating, and a lens. The semiconductor chip is the heart of the LED, where the UV light is generated. The phosphor coating is applied to convert the UV light into visible light, making it suitable for various applications. The lens helps to focus the light and enhance its intensity.
