Abstract:
A camera flash unit for illumination of an associated target surface comprising:(i) a light source providing light defined as light rays;(ii) a reflector directing the light rays from said light source towards the associated target surface, said reflector including one closed end, one open end, and highly reflective, curving inner walls, said inner surface walls being symmetrical about at least one axis of symmetry; and(iii) a refractive lens component located at said open end, said refractive component having two surfaces--a back side surface facing said light source and covering said opening and a front side surface, both of said surfaces intercepting and being centered on aid line of symmetry, one of said surfaces being a cylindrical surface, the other of said two surfaces being a toroidal surface and adapted to direct non collimated, fanned light rays toward the target surface.
