Abstract
An asymmetric lamp with an improved reflector assembly is disclosed. The lamp includes a head, a socket for receiving a light bulb, and a front reflector. The socket and the front reflector are mounted in the head. When the light bulb is inserted into the socket, the light bulb defines a transverse axis. The front reflector has a longitudinal cross-sectional shape that is either generally hyperbolic, generally parabolic, or generally elliptic. The front reflector is formed from a plurality of triangular facets. Adjacent facets define a line that is nonparallel to the transverse axis defined by the light bulb. The front reflector is mounted in the head so that the rear edge of the front reflector is positioned proximate the top of the light bulb. The lamp may include a back reflector, preferably made from a nonconductive material. The back reflector is positioned proximate the rear edge of the front reflector. The back reflector may have rounded upper and lower portions, which conform to the rounded top and bottom sections of the light bulb. The lower portion of the back reflector may extend forward of the bottom of the light bulb, and a notch may be formed in the lower portion of the back reflector. One or more louver strips may be located at the front edge of the front reflector.
