Guangmai Technology is professional in making the Ceramic Substrated 1W UVB SMD LED Chip for Skin Treatment.
With the rising star of deep-ultraviolet LEDs, UVA and UVC LEDs have gradually replaced traditional mercury lamps and gradually occupy the market. However, for the application field of UVB LED, everyone is still exploring, it is certain that phototherapy is a new and predictable direction.
Phototherapy is a method that uses electromagnetic radiation to produce light of different wavelengths to treat skin diseases.
Most of the UV lamps currently in use are mercury lamps, which generate electromagnetic wave radiation through the ionization of mercury vapor in the mercury lamp to excite the discharge. Single wavelength type and fragility are typical problems of mercury lamps, and the heavy metal mercury in them is likely to cause serious harm to the human body and the environment. On August 16, 2017, the "Minamata Convention on Mercury" came into effect. 128 signatories, including China, pledged to reduce mercury emissions and use, and protect the public from man-made mercury pollution. Among them, the regulation of handicraft industry means that mercury lamps will be gradually banned. At this time, LED came into being with the advantages of small size, cold light source, energy saving and environmental protection, and no need for preheating. Many companies are already actively deploying the application of UVB LED, and a new era of phototherapy is coming. At present, Guangmai Technology has developed a UVB LED with a peak wavelength of 310 nm and a half-wave width of only 10 nm. The concentration of wavelengths is more advantageous for phototherapy.
