Abstract:
A mirror device comprising;a. a mirror plate having a reflective surface,b. a frame having a front portion which at least partially encircles the periphery of said mirror plate, said frame comprising a ring-shaped body for conducting light from an entrance surface to an exit surface thereof, said body being made of a material which is at least partially light-transmissive, said body having a front ring-shaped light exit surface, a rear light entrance surface, and an intermediate portion disposed between said front and rear surfaces, said intermediate portion having an arcuately curved, convex outer surface which is inclined to light rays entering said rear light entrance surface at an angle greater than the critical angle for total internal reflection of said material, andc. a light source effective in introducing light rays through said rear light entrance surface into said intermediate portion of said body, said rays impinging on said curved outer surface at an angle greater than said critical angle, whereby said rays are conducted from said rear light entrance surface to said front light exit surface by total internal reflection.
