Vishay VLMU35CL2.-275-120 series of ultraviolet LEDs are designed for germicidal applications for disinfection of bacteria and viruses. The ceramic based UVC LED comes with silicone lens for long life operation. Devices have been effective in disrupting certain microbe’s DNA and therefore eliminating the microorganisms in exposed environments. Common applications include sterilizations of hospital rooms and surgical areas, ambulances and publics spaces. LED size is 3.45mm x 3.45mm x 1.38mm and the radiant power is typically 2.5mW at 20mA in a wavelength range of 265nm to 285nm. The surface mount LEDs are suitable for creating a large area panel light sources to produce the high intensity required for them to be effective.
