Display element and mechanical mounting interface used therein

Abstract

A display element consisting of a display panel on which one or more lighting modules are fastened, wherein said display element includes a mechanical mounting interface for fastening said lighting module to said display panel.

1 . A display element comprising a display panel on which one or more lighting modules are fastened, said display element further comprising a mechanical mounting interface arranged to fasten said lighting module to said display panel; 
 wherein said display panel is provided with an array of slots arranged to receive said lighting modules.    
   
   
       2 . The display element according to  claim 1 , wherein said mechanical mounting interface comprises latches arranged to cooperate with the slots by clicking behind the edges of said slots.  
   
   
       3 . The display element according to  claim 2 , wherein said latches are hinge-mounted at one end on said lighting module and are provided with a rim projecting from said hinge-mounted end.  
   
   
       4 . The display element according to  claim 3 , wherein the lighting module is provided with holes in front of said rims, to thereby enable said rims to be accessed through said holes from the front side of said lighting module in order to unlock said latches.  
   
   
       5 . The display element according to  claim 3 , wherein said mechanical mounting interface comprises a lever that is hinge-mounted on said lighting module and that is provided with a pawl cooperating with said rim.  
   
   
       6 . The display element according to  claim 5 , wherein said lever is hinge-mounted at one edge on said lighting module and wherein said lever is provided with two pawls, one on each end of the hinge-mounted edge of said lever, such that when the lever is lifted, said pawls lift the rims of said latches in order to unlock the lighting module.  
   
   
       7 . The display element according to  claim 5 , wherein said lighting module is provided with a hole in front of said lever, thereby providing access to said lever through said hole from the front side of said lighting module.  
   
   
       8 . The display element according to  claim 2 , wherein said latches are bent inwardly towards the lighting module, such that the distance between the hinge-mounted ends of two corresponding latches is larger than the distance between the two corresponding edges of the slots in said display panel cooperating with said latches, and wherein the mechanical mounting interface further comprises at least one spring projecting from the back side of said lighting module and a hinge-mounted lever on said lighting module, thereby enabling the free end of the latches to cooperate with said lever to thereby maintain said latches in an inwardly hinged position.  
   
   
       9 . The display element according to  claim 8 , wherein said lighting module is arranged to be fastened to said display panel with said mechanical mounting interface by pushing said lighting module in one of said slots, such that said latches click with their free ends behind the edges of said slot, and wherein the lighting module is arranged to be subsequently released by pushing said lighting element further in said slot in a direction against the force of the springs, so that the edges of said slot interact with the curve in said latches, such that the latches are pushed aside with their free ends under said lever.
