ABSTRACT:
A lighting device having a light source L and a reflector R positioned behind the light source is disclosed in which a three-dimensional configuration is given to the reflector R with the aid of the computer so that it can provide a particular reflection pattern to the light reflected by the reflector R. Due to a particular curvature or configuration of the reflecting surface of the reflector R, the light rays emanating from the light source and reflected at any point on the reflecting surface intersect or cut across each other at innumerable different points in space. Further, the reflector is provided with a three-dimensional curvature or shape so that it can give the incident light rays a preselected luminous flux distribution. The lighting device is adapted for application in a variety of uses enabled by its special reflection paths of light rays.
