Item description

“Transparent fluoride polymer material.“ - Essential materials for commercialization of UVC-LED chips protect chips from external heat, moisture, physical shocks, etc. to secure product stability and life and improve light efficiency. - material (stability, heat resistance, permeability) that can be secured without any external deformation, such as crack, or external deformation even after prolonged exposure to UVC energy (stability, heat resistance, permeability). - Thermal stability in the Deep UV area and high binding energy compared to silicon materials for conventional LEDs using high-molecular fluoride materials.

“UV-LED Light  Diffusion Plate” - Light diffusion plates/sheets with transmittance rate and scattering optimized for the product of the demand source by applying the scattering method that occurs as light passes through the air pore. - Various optical characteristics can be implemented in client products by utilizing air pore layer control technology, air pore layer dispersion technology, and coating layer solution manufacturing recipe. - Unlike existing competitor parts, which are manufactured in the form of plastic extrusion that can only be applied to visible light wavelengths, the company has a competitive edge. Manufacture of light diffuser plate optimized for light source using one time coating on the base substrate(Glass, Plastic)

“Integrated module of light diffusion structure” - Integrated module of photo-diffusion structures with developed polymer materials. - Enables the transmission of energy unique to light sources without changing wavelengths from UV to visible light areas. - Uniform energy transfer is possible through the spread of light sources. - Applicable to various applications (medical,beauty, etc.)
