ABSTRACT:
A lamp combination wherein the reflector's reflective surface is of a shape specifically designed to compensate for the refractive effects produced by the thickness of the glass walls of the light source's envelope structure located within (surrounded by) the reflector. Optimum light output is thus assured. A method of making such a lamp is also disclosed.
