US 10,118,170 B1 · Anti-bacterial lighting apparatus

Abstract

A lighting apparatus that includes at least one light source and at least one transparent or translucent lens, and at least one anti-bacterial composite film. The anti-bacterial composite film that includes photocatalytic particles and nano silver particles is formed on at least a part of the outer surface of the lens. With this anti-bacterial composite film, the lighting apparatus retains its germicidal function when the light source is turned off. Moreover, at least 95% of the spectral power distribution (SPD) of the light source comes from the visible light wavelength range (>400 nm). Artificial light sources such as LED can also be used with the anti-bacterial lighting apparatus.
