UV-C LED Chips

Description

UV-C LED chips are a specific type of LED chip that emit ultraviolet (UV) light in the UV-C spectral range, which is between 200 and 280 nanometers (nm) in wavelength. UV-C light has germicidal properties, meaning it can kill bacteria, viruses, and other microorganisms by disrupting their DNA and preventing them from reproducing.

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

UV-C LED chips are used in a variety of applications, including water and air purification, surface disinfection, and medical sterilization. They offer several advantages over traditional UV-C lamps, including longer lifetimes, lower power consumption, and smaller size. However, UV-C LED chips also face several challenges, such as lower efficiency and higher costs compared to traditional UV-C lamps. Ongoing research and development in the field of UV-C LED technology aim to address these challenges and improve the performance and availability of UV-C LED chips.

UV-C LED chips, also called deep UV (DUV) LED chips find its application mainly in sterilization, desinfection, water and air purification. Some research about using deep UV LED chips is done in horticulture to provide longer shelf life of fruits and vegetables. In COVID era germicidal effect of UV-C LEDs is widely stidied and many compact disinfection devices were developed for personal use.
