Method and apparatus for preventing a build up of snow or dust

Abstract

An apparatus for preventing a build up of snow or dust. The apparatus includes a plurality of air nozzles positioned around a periphery of a target area to be kept clear of snow or dust. Each of the nozzles directs a stream of air away from the target area. A deflector is positioned around a periphery of the target area. The deflector deflects the stream of air from each nozzle across the target area, wherein an air curtain is formed preventing snow or dust from landing on the target area.

1 . An apparatus for preventing a build up of snow or dust, comprising:
 a plurality of air nozzles positioned around a periphery of a target area to be kept clear of snow or dust, each of the nozzles directing a stream of air away from the target area;   a deflector positioned around a periphery of the target area, the deflector deflecting the stream of air from each nozzle across the target area wherein an air curtain is formed preventing snow or dust from landing on the target area.   
     
     
         2 . The Apparatus of  claim 1 , wherein the target area is a light. 
     
     
         3 . The Apparatus of  claim 2 , wherein the deflector is transparent in order to prevent the deflector from obscuring visibility of the light. 
     
     
         4 . The Apparatus of  claim 1 , wherein each of the air nozzles are duck bill nozzles. 
     
     
         5 . The Apparatus of  claim 1 , wherein the deflector has drainage holes to drain liquids away from the target area. 
     
     
         6 . The Apparatus of  claim 1 , wherein an air source providing air to the air nozzles is independent of other air systems. 
     
     
         7 . The Apparatus of  claim 6 , wherein the air source has a battery as a power source. 
     
     
         8 . The Apparatus of  claim 7 , wherein the battery provides power solely to the air source. 
     
     
         9 . A method for preventing a build up of snow or dust, comprising:
 directing stream of air from a plurality of air nozzles across a target area to form an air curtain which prevents snow and dust from landing on the target area.
