Abstract

An SMD LED that is designed for indoor use is equipped for outdoor use by encapsulation in a vacuum-forming and/or cover molding covering, which is placed over the indoor SMD LED and is formed thereon by evacuation. The thus-equipped indoor SMD LED is thereby usable in the same manner as a more expensive and ruggedly designed outdoor SMD LED.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An outdoor SMD LED comprising:
 an indoor SMD LED; and   a covering held in place over said indoor SMD LED by evacuation between said covering and said SMD LED.   
     
     
         2 . The outdoor SMD LED of  claim 1 , wherein said covering is a vacuum-forming covering or a cover molding covering. 
     
     
         3 . The outdoor SMD LED of  claim 2 , where the covering is made of plastic or silicone. 
     
     
         4 . An outdoor SMD LED display, comprising:
 a printed circuit board;   a plurality of LEDs mounted to a same surface of said circuit board and forming, in combination with said circuit board, an indoor LED display; and   a vacuum-forming and/or cover molding covering placed over said LEDs on said surface of said printed circuit board, and held in place over said LEDs on said printed circuit board by evacuation of a volume between said covering and said LEDs on said circuit board, thereby forming a protection for said indoor LED display allowing outdoor operation thereof.   
     
     
         5 . The outdoor SMD LED display of  claim 4 , wherein said vacuum-forming and/or cover molding covering is made of plastic or silicone. 
     
     
         6 . A method for equipping an indoor SMD LED for outdoor operation, comprising:
 providing an indoor SMD LED; and   vacuum-forming and/or cover molding a cover on said indoor SMD LED, thereby protecting said indoor SMD LED for outdoor operation.   
     
     
         7 . The method for equipping an indoor SMD LED for outdoor operation of  claim 6 , wherein said cover is made of plastic or silicone.
