UV LEDs have become a popular alternative to traditional mercury vapor lamps for numerous applications.uv led chip They offer many benefits including a compact design, long operating life, low maintenance costs, hermetic seal, power control, clear line spectrum, and minimal heat generation. They also operate at lower voltage resulting in increased safety. In addition, uv led chip do not produce ozone and are RoHS compliant to ensure compliance with environmental standards.
UV emits photons in the wavelength range 100-400nm, which is invisible to the human eye.uv led chip The spectral lines of UV are divided into three categories: UV-C, UV-B, and UV-A. In the past, the only way to generate UVC was by using high-voltage arc-discharge mercury lamps. However, newer UVC LEDs have been developed with much lower energy requirements and provide germicidal effects for medical sterilization, water treatment, currency & document validation, forensics, and other specialized applications.
Nichia’s UV-C LED products are based on a new silicon pn junction structure that achieves high hermeticity by sealing the chip in a special mold with metal with high resistance to UV radiation.uv led chip This technology allows the chips to be packaged in a variety of shapes and sizes without compromising optical output power or efficiency.
In contrast to traditional UV bulbs, Nichia’s UV-C LEDs feature a narrow peak wavelength for maximum sterilization effectiveness.uv led chip They are ideal for disinfecting medical tools and instruments, curing adhesives, and other industrial processes.
The 308nm wavelength in the UV-B range is best suited for industrial curing and analysis, as it sterilizes objects and substances in a short period of time.uv led chip It is also highly effective for detecting counterfeit bills and other documents and materials.
Lastly, the 305-410nm range in the UV-A region is useful for a wide range of applications including enhancing light efficiency for solar cells and LEDs, medical sterilization, spectrophotometers, and UV-vis spectroscopy equipment.uv led chip It is also used for a range of photocatalytic reactions and photochemical processes.
