How Do UV LED Modules Work? Understanding UV LED Technology
What is a UV LED? Ultraviolet light-emitting diodes (UV LEDs) are examples of semiconductor-based electronic devices that generate ultraviolet light (UV) radiation as a result of passing an electric current through them. Unlike incandescent and fluorescent lamps, UV LED emitters are more robust and energy efficient since they do not have any moving elements. Core Functionality & Scientific Principles The introduction of new technologies has practically made UV LEDs useful for many different purposes. These include printing, medical sterilization, water treatment, etc. In this post, we will look at the science, design, performance, and application of UV LED modules. How Do UV LEDs Emit Light? Semiconductor Materials Used in UV LEDs • AlGaN (Aluminum Gallium Nitride): Ideal for emitting deep UVC radiation (200–280 nm). Provides high thermal stability and photon efficiency. • GaN (Gallium Nitride): Used for UVA and UVB range emissions because of its strength and high electron mobility. • InGaN (Indium Gallium Nitride): Can be tailored to emit specific wavelengths, providing customization for certain applications. These materials help engineers optimize UV LEDs for various industrial and scientific uses. Components & Design of UV LED Modules The chip is the basic component that produces UV light. Its mounting ...
