Introduction to 365nm UV LED Diodes

365nm UV LED diodes are a type of solid-state lighting technology that utilizes light-emitting diodes (LEDs) to produce UV light at a very specific wavelength. Unlike traditional UV lamps that use mercury vapor or other harmful substances, UV LED diodes are environmentally friendly, energy-efficient, and have a longer lifespan. The 365nm wavelength falls within the UVA range of the UV spectrum, which is particularly useful for various applications that require deep-penetrating UV light.

Working Principles of 365nm UV LED Diodes

The working principle of 365nm UV LED diodes is based on the semiconductor physics of gallium nitride (GaN) and other compound semiconductor materials. When an electric current is applied to the diode, electrons and holes recombine within the semiconductor material, releasing energy in the form of photons. The specific energy released determines the wavelength of the light emitted. In the case of 365nm UV LED diodes, the semiconductor material is carefully engineered to emit light at this particular wavelength.
