Power of the Sun \ Ultraviolet Germicidal Irradiation Sterilization

The light emitted from the sun includes a particular wavelength range called UV-C that is able to penetrate the protective wall and nucleic acids of microorganisms and interrupt their DNA/RNA structure, leaving bacteria, fungi, viruses, and other pathogens unable to perform vital cellular functions and reproduce. However, naturally occurring UV-C light is filtered out by the earth’s atmosphere and does not reach the surface where humans reside.

Developments in lighting technology that creates UV-C wavelengths artificially have made sterilization by ultraviolet irradiation possible, and its application in the medical field has been standard practice since the 1950s. Since then, applications have evolved into the treatment of food production facilities, air, and water. By leveraging modern developments in LED technology that offers smaller sizes and less power consumption, UVengers UV1 is able to harness power of the sun and germicidal properties of UV-C light.
