Patent ID: 10874762

Abstract:
An anti-bacterial lighting apparatus includes one translucent housing, at least one light source, and an air circulation mechanism. The translucent housing is air permeable, has as least one air inflow port, and has an anti-bacterial photocatalytic film on its inside surface. The at least one light source is inside the housing, and its light activates the anti-bacterial photocatalytic film on the housing. The air circulation mechanism, such as a fan, is at the air inflow port of the housing. It sucks the ambient air from outside the housing and forces the air through the air-permeable housing. The air-permeable housing traps airborne bacteria and viruses, and the activated anti-bacterial photocatalytic film kills the trapped bacteria and viruses. Moreover, the light shines through the translucent housing while the apparatus is filtering the air and killing the airborne bacteria and viruses.
