UV-A LED Chips


UV-A LED chips are a type of LED chip that emit ultraviolet (UV) light in the UV-A spectral range, which is between 315 and 400 nanometers (nm) in wavelength. UV-A light is often referred to as "black light" because it causes certain materials to fluoresce or glow in the dark.

UV-A LED chips are typically made from a semiconductor material, such as aluminum gallium nitride (AlGaN) or gallium phosphide (GaP), which has a bandgap energy that corresponds to the UV-A wavelength range. These materials are doped with impurities to create a p-n junction that can emit UV-A light when a voltage is applied.

UV-A LED chips are used in a variety of applications, including counterfeit detection, insect trapping, and curing of adhesives and coatings. They offer several advantages over traditional UV-A lamps, including longer lifetimes, lower power consumption, and smaller size. However, UV-A LED chips also face challenges, such as lower efficiency and higher costs compared to traditional UV-A lamps. Ongoing research and development in the field of UV-A LED technology aim to address these challenges and improve the performance and availability of UV-A LED chips.
