ABSTRACT:
A back lighting device includes a light waveguide having generally planar upper and lower surfaces, a light module having a lamp member encapsulated between the upper and lower surfaces, a specular reflective material applied about the waveguide lower surface, and a light extracting material applied about the waveguide upper surface. The waveguide can be mounted in a user specific frame to allow high volume usage of a common waveguide element.
