ABSTRACT:
A lighting device operable with solar beams propagating through and emitting from the optical wave guides. A pair of spaced concave and convex reflecting members are provided to effectively diffuse the solar beams issuing from the exit end of the optical wave guides. One of the reflecting members may be constituted by a mirrored electric bulb in order to ensure the lighting device to operate also by electric power.
