摘要:
A concave light reflector is shaped to have flat-sectioned radial bands on its inner surface extending radially outwardly and forwardly from the apex of the reflector. The bands are distributed circumferentially in an asymmetrical manner to provide a desired cross-sectional contour of illumination intensity, such as approximately rectangular for photographic projection purposes.
