Abstract
The present system provides a compact light diffusing and mixing structure for uniformly dispersing light at an exit surface, the apparatus having a light entrance surface which faces a light exit surface located on the opposite side of the light diffusing and mixing structure; a beam splitter light guide assembly located between the entrance and exit surface; a reflective surface located adjacent to the beam splitter light guide assembly. The light diffusing structure works such that light entering the entrance surface on striking the beam splitter light guide assembly is directed in part directly towards the exit surface and in part towards the reflective surface which in turn directs the light towards the exit surface and thereby evenly diffusing or dispersing the light across the exit surface. The system also provides a compact fast battery charger for Ni-MH and NiCAD batteries. The charger can indicate the degree of charge of the battery during a charging state and a discharging state.
