Systems and Apparatus for Ultraviolet Light Disinfection

Abstract

A disinfection system is provided herein. The disinfection system includes an UV light source to generate UV light and a housing supporting the UV light source. The housing includes a fan and a shield having a body partially surrounding the UV light source. The body has an inner surface sized and shaped to reflect the UV light from the UV light source. The body defines at least one hole configured to receive air flow from the fan and direct the air flow to contact the UV light source to control a temperature of the UV light source.

1 . A disinfection system comprising:
 an UV light source to generate UV light; and   a housing supporting the UV light source, the housing comprising:
 a fan; and 
 a shield having a body partially surrounding the UV light source, the body having:
 an inner surface sized and shaped to reflect the UV light from the UV light source; and 
 the body defining at least one hole positioned above the UV light source and configured to receive air flow from the fan and direct the air flow to contact the UV light source to control a temperature of the UV light source. 
 
   
     
     
         2 . The disinfection system of  claim 1 , wherein the inner surface of the shield is sized and shaped to reflect the UV light from the UV light source in a direction away from the housing. 
     
     
         3 . The disinfection system of  claim 1 , wherein the body of the shield is an elongate member. 
     
     
         4 . The disinfection system of  claim 1 , wherein the body of the shield is curved. 
     
     
         5 . The disinfection system of  claim 1 , wherein the body of the shield is semi-circular. 
     
     
         6 . The disinfection system of  claim 1 , wherein the at least one hole includes at least one slot. 
     
     
         7 . (canceled) 
     
     
         8 . The disinfection system of  claim 1 , wherein the holes include slots. 
     
     
         9 . The disinfection system of  claim 8 , wherein the holes are regularly spaced along a length of the body. 
     
     
         10 . (canceled) 
     
     
         11 . (canceled) 
     
     
         12 . The disinfection system of  claim 1 , wherein the body is made of anodized aluminum. 
     
     
         13 . The disinfection system of  claim 1 , wherein the inner surface is made of anodized aluminum. 
     
     
         14 . A housing to support an UV light source, the housing comprising:
 a fan; and   a shield fluidly coupled to the fan; the shield having a body partially surrounding the UV light source, the body having:
 an inner surface sized and shaped to reflect the UV light from the UV light source through the opening; and 
 the body defining a hole positioned above the UV light source and configured to receive air flow from the fan and direct the air flow to impinge the UV light source to control a temperature of the UV light source. 
   
     
     
         15 . The housing of  claim 14 , wherein the inner surface of the shield is sized and shaped to reflect the UV light from the UV light source in a direction away from the housing. 
     
     
         16 . The housing of  claim 14 , wherein the body of the shield is an elongate member. 
     
     
         17 . The housing of  claim 14 , wherein the body of the shield is curved. 
     
     
         18 . The housing of  claim 14 , wherein the body of the shield is semi-circular. 
     
     
         19 . The housing of  claim 14 , wherein the at least one hole includes at least one slot. 
     
     
         20 .- 26 . (canceled) 
     
     
         27 . A shield to reflect UV light from an UV light source, the shield comprising:
 a body partially surrounding the UV light source, the body having:
 an inner surface sized and shaped to reflect the UV light from the UV light source; and 
   the body defining a hole positioned above the UV light source and configured to receive air flow from a fan and direct the air flow to impinge the UV light source.   
     
     
         28 . The shield of  claim 27 , wherein the inner surface is sized and shaped to reflect the UV light from the UV light source in a direction away from the housing. 
     
     
         29 . The shield of  claim 27 , wherein the body is an elongate member. 
     
     
         30 . The shield of  claim 27 , wherein the body is curved.
