Antimicrobial lighting system
First Claim
Patent Images
1. A lighting system comprising:
- a light fixture including a light diffuser;
the light diffuser configured to be exposed to air, and comprising a micro-structured surface pattern at an outer surface thereof; and
a blended layer comprising an antimicrobial additive in the form of a coating as a separate layer applied to the micro-structured surface pattern of the light diffuser,wherein the blended layer together with the micro-structured surface pattern on the outer surface of the light diffuser are configured to perform optical veiling and diffusing light while controlling growth of microbes onto the light diffuser of the light fixture.

Abstract
Provided is a system enhancing control of bacterial growth by combining antimicrobial additives and surface micro-structure patterns on outer surfaces of a device, such as a lighting fixture. The system physically decreases bio-adhesion between microbes and substrates applied to the outer surfaces. The system combines a surface micro-structured component with an antimicrobial component to generate a single component.

8. A method of use of a lighting system, comprising:
-
providing a light diffuser of a light fixture configured to be exposed to air; forming a micro-structured surface pattern on an outer surface of the light diffuser; applying a blended layer comprising an antimicrobial additive as a separate layer in the form of a coating to the micro-structured surface pattern of the light diffuser; and performing optical veiling and diffusing light using the blended layer and the micro-structured surface pattern while controlling, by the micro-structured surface pattern and the blended layer, growth of microbes onto the light diffuser of the light fixture. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
