Claim:
A rear view mirror assembly for a motor vehicle, said rear view mirror assembly comprising: a mirror base adapted to be secured to the motor vehicle; a mirror case movably secured to said mirror base, said mirror case defining a mirror opening rearward thereof; a backing plate operatively mounted to said mirror case and movable with respect to said mirror case, said backing plate defining a backing plate surface and forming an integrated mounting space defining a mounting surface spaced apart from said backing plate surface; a mirror glass fixedly secured to said backing plate surface of said backing plate, said mirror glass having a reflective surface; a printed circuit board mounted to said mounting surface, said printed circuit board including a light source; and a light guide tray mounted to said mounting surface and being wedge-shaped in cross section along its y-axis starting from its front face disposed adjacent to and spaced apart from said light source to provide an area for free travelling of light emitted by said light source before it is received by said front face of said light guide tray, said light guide tray declining slightly with an inner declining surface reflecting light by total reflection conditions, wherein said inner declining surface defines a plurality of arcuate tile segments each lower than the next and having a first radius such that said each of said plurality of arcuate tile segments is curved with said first radius in cross section along its z-axis to form said light guide tray, wherein said light guide tray has a plane surface parallel to said mirror glass opposite said declining surface; and wherein said mirror glass visible through said mirror opening of said mirror case and covering said backing plate, defines a transmissive area disposed adjacent said light source and said light guide to allow light emitted by said light source to pass therethrough.
