ABSTRACT:
A reflector lamp or illumination system comprising a concave reflector having a parabolic or ellipsoidal front section and a spherical rear section with it's focal point just ahead of the focal point of the front section, and a finite light source located at the focal point of the front section. The reflector sections are dimensioned so that light rays from the finite light source which are reflected by the spherical rear section become re-reflected by the front section and distributed more evenly in said projected beam pattern with the energy rays filling back in from the edge to the center. Additionally the light rays, re-reflected by the front section, are made up of uncompressed light and energy components which provide a beam pattern which is substantially more even in light and energy distribution, does not have compressed light and energy producing hot spots of light and heat at the center of the projected beam pattern or gate, and is therefore less harmful to parts such as lighting fixture parts, plastic lens and items being projected such as plastic color media, film, and slides.
