ABSTRACT:
A luminaire useful in illuminating a task area and having particular application for roadway lighting includes a monochromatic light source which is preferably a low pressure sodium lamp which can be an elongated tubular light source disposed within a housing defined by a reflector having a configured reflection surface to principally control light distribution along the length of the roadway with the lamp being at least partially surrounded and in a specific embodiment totally surrounded by a cylindrical tube acting as a substrate for a multilayer interference mirror to principally control light distribution across or transverse to the roadway. This combination of elements, in particular cooperation with their specific configurations, provides a predetermined light pattern on a task surface such as the example roadway.
