ABSTRACT:
A car number plate lamp having an improved illuminating efficiency and more uniform illuminating intensity. A light source and lens are provided in a lamp body, and a lens is mounted across an opening in the lamp body. The reflector is three-dimensionally curved in such a manner that the entire surface of the reflector viewed in the longitudinal direction curves circular-arcuately about the light source. The surface perpendicular to the longitudinal direction forms a paraboloid with the light source at the focal point. Concentric steps for refracting the light from the light source to the number plate are formed in the inner surface of the lens.
