At a time when the entire world is trying to arrive at plausible solutions to arrest the spread of this rampaging virus, our Lighting fraternity has joined the fight by concentrating more on studies of non-visual impacts of light. An invisible part of the optical radiation spectrum, ultraviolet radiation has more energy than its visible counterpart due to its shorter wavelengths. The ultraviolet spectrum comprises UV-A (400 nm to 315 nm); UV-B (315 nm to 280 nm); UV-C (280 nm to 100 nm) – classification as defined by CIE. Whenever ultraviolet radiation is used for germicidal purposes, it is known as GUV (Germicidal Ultraviolet ) radiation. It has been found to be highly effective in deactivating or killing virus...
