Benefits of V-Go™ vs. Alternatives* Wipes and chemicals require adequate contact and drying times
LEDs vs. Lamps
Based on published research, UVC LEDs offer advantage over lamps in germicidal efficacy compared at the same wavelength and intensity. This is attributed to greater scattering of light from a conventional UV lamp compared with a properly designed and collimated LED system that can converge and focus the UVC light in one direction. LEDs also have an advantage that they don’t require a warmup time like lamps before they reach optimum efficacy and are friendlier to environment as they contain no Mercury.
Optimized Spatial Arrangements
Our patent pending V-Go™ includes LEDs at two different wavelengths, is designed for safety using proprietary electronics. To maximize efficacy, we optimized our LED layout by examining various spatial arrangements as shown in Figure 1. Our objective is to deliver an effective dose (fluence) more uniformly, across a given surface area to inactivate diverse groups of germs. Irradiance plots at different heights are shown in Figures 2 and 3.
