Light emitting diode reflector

Abstract

A reflector for a circular array of LEDs each having a housing and a front portion for emitting a main beam of light, the reflector comprising a body defining a plurality of radially extending cavities in which the LEDs may be at least partially located, comprising: (a) at least one wall to substantially surround the perimeter of the housing, said wall being spaced from the housing and adapted to reflect incident light from the LED along the cavity towards an open end of that cavity; and (b) a fastener to releasably fasten the LEDs at least partially in the cavity.

1 . A reflector for a circular array of LEDs each having a housing and a front portion for emitting a main beam of light, the reflector comprising a body having an axis said body defining a plurality of cavities extending radially from the axis in which the LEDs may be at least partially located, comprising: 
 (a) at least one wall to substantially surround the perimeter of the housing, said wall being spaced from the housing and adapted to reflect incident light from the LED along the cavity towards an open end of that cavity; and    (b) a fastener to releasably fasten the LEDs at least partially in the cavity.    
     
     
         2 . A reflector according to  claim 1 , wherein the space between the at least one wall and the housing defines a gap through which light passes towards the open end of that cavity.  
     
     
         3 . A reflector according to  claim 1 , wherein the space between the at least one wall and the housing is filled with a transparent medium through which light passes towards the open end of that cavity.  
     
     
         4 . A reflector according to  claim 1  wherein the depth of the cavity approximates the depth of the LED.  
     
     
         5 . A reflector according to  claim 1  wherein the at least one wall extends from the body to define a pair of divergent surfaces.  
     
     
         6 . A reflector according to  claim 1 , wherein the at least one wall is substantially concave in shape.  
     
     
         7 . A reflector according to  claim 1 , wherein the at least one wall is axially symmetrical.  
     
     
         8 . A reflector according to  claim 1  wherein the at least one wall comprises ridges to increase the amount of light reflected towards the open end of that cavity.  
     
     
         9 . A reflector according to  claim 1  wherein the body comprises at least two parts which are connectable together.  
     
     
         10 . A reflector according to  claim 9  wherein the body comprises complimentary parts.  
     
     
         11 . A reflector according to  claim 9  wherein the body comprises identical parts.  
     
     
         12 . A reflector according to  claim 9  wherein the fastener is formed by connection of the complimentary parts.  
     
     
         13 . A light comprising a plurality of reflectors according to  claim 1  and a plurality of LEDs located therein.  
     
     
         14 . A reflector for a circular array of LEDs, each having a housing and a front portion for emitting a main beam of light, the reflector comprising a body having an axis said body defining a plurality of cavities extending radially from the axis in which the LEDs may be at least partially located, comprising: 
 (a) at least one wall to substantially surround the perimeter of the housing, said wall being spaced from the housing and adapted to reflect incident light from the LED along the cavity towards an open end of that cavity; and    (b) a fastener to releasably fasten the LED at least partially in the cavity wherein the body comprises at least two complimentary circular parts which are connectable together.    
     
     
         15 . A reflector according to  claim 14  wherein the circular parts are discs.  
     
     
         16 . A reflector according to  claim 14  wherein the circular parts are rings.  
     
     
         17 . A reflector according to  claim 14  wherein the circular parts are identical.  
     
     
         18 . A light comprising a plurality of reflectors according to  claim 14 .  
     
     
         19 . A light comprising a reflector for a circular array of LEDs each having a housing and a front portion for emitting a main beam of light, the reflector comprising a body having an axis, said body defining a plurality of cavities extending radially from the axis in which the LEDs may be at least partially located, comprising: 
 (a) at least one wall to substantially surround the perimeter of the housing, said wall being spaced from the housing and adapted to reflect incident light from the LED along the cavity towards an open end of that cavity; and    (b) a fastener to releasably fasten the LED at least partially in the cavity wherein the body comprises at least two complimentary circular parts which are connectable together.    
     
     
         20 . A light according to  claim 19  wherein the circular parts are discs.  
     
     
         21 . A light according to  claim 19  wherein the circular parts are rings.  
     
     
         22 . A light according to  claim 19  wherein the circular parts are identical.
