ABSTRACT:
A luminaire for illuminating a surface area spaced from the luminaire nadir to a distance from its elevated mounting. The luminaire has an elongated light source with its axis substantially parallel to the surface being illuminated. A specular reflector disperses the light over a range from substantially the light nadir to a line about 73.degree. from the nadir. With the present construction, a series of beams, each of about 1.degree. in angular extent, is approximated to provide uniform light distribution over a designated angular spread with sharp cutoffs beyond the spread with a high utilization factor for the light generated. The reflector is configured to prevent reflected light from passing through the light source although beams of at least one section are directed in paths closely adjacent to the light source.
