For instance, a 20W LED driver can be used to power 18W UV-C LED array to sterilize 99.9% of germs over a 45~60 cm surface for about 5 mins.
Table 1 shows LED driver output power needed for a UV-C sterilization LED light to sterilize 45~60 cm and 180~420 cm over the surface. Also, it often designs with programmed on and off control to sterilize a surface by cycles such as 15 mins or 30 mins per sterilization.ĭistance, time, and on/off control are directly related to select an appropriate LED driver to drive the UV-C LEDs. Thus, time and distances are critical parameters of UV-C sterilization LED light. The curve of figure 2 shows the distance vs time that it takes about 5 mins for 45cm and about 18 mins for 100 cm to 99.9% sterilize the surface. To effectively sterilize germ, the UV-C LED is fabricated with 100% intensity concentrated at 275nm wavelength. Figure 1a shows the relative intensity of a UV-C LED with 100% relative intensity at 275nm vs the illumination LEDs of Figure 1b. Unlike LED used for illumination, the UV-C LED emits violet or purple color spectrum at typically 275nm wavelength and the relative intensity peaks at 275nm wavelength as compare to the scattered wavelengths of illumination LED.

This whitepaper discusses the UV-C LED and UV-C sterilization LED Light and suitable MEAN WELL LED drivers for UV-C LED Lighting. Other companies are working to add UV-C LED light to existing products to disinfect frequently touched surfaces such as banking machines. Thus, UV-C LED lighting has become popular that companies are investing resources to design UV-C LED light fixtures to be used in hotels, car trains or hospitals. Currently, Low-pressure Mercury UV-C Sterilization light is also used but it consumes more energy and requires wait time to start up the sterilization cycles. Ultraviolet C (UV-C) Sterilization LED Lighting is one of the Pandemic (Covid-19) blooming market that mainly aims to disinfect germs for surface contacts.
