Introduction to High Power 405nm UV LED

High power 405nm UV LED refers to a type of light-emitting diode (LED) that emits ultraviolet (UV) light at a wavelength of 405 nanometers. These LEDs are designed to provide a high intensity of light, making them ideal for various applications where specific wavelengths of UV light are required. The 405nm wavelength falls within the UV-A range, which is less harmful to human skin compared to UV-B and UV-C wavelengths.

How High Power 405nm UV LED Works

The working principle of a high power 405nm UV LED is similar to that of other LEDs. It consists of a semiconductor material, typically gallium nitride (GaN), which emits light when an electric current passes through it. The GaN material is doped with other elements to create a p-n junction, which generates UV light when excited. The key to achieving high power output lies in the design and construction of the LED. High power 405nm UV LEDs typically feature a larger die size, which allows for more semiconductor material and, consequently, more light emission. The use of advanced packaging techniques and heat sinks further enhances the efficiency and performance of these LEDs.
