The concave reflecting surface of a projector lamp reflector is shaped in the form of a plurality of radial bands and a plurality of concentric circular bands to provide a multiple faceted surface for spreading the image formed by the reflector into a larger and smoother pattern and reducing the amount of imaging of a lamp filament and support post in the projected light pattern. Longer life and improved reproducibility of the molding tool are achieved.
