LUMINAIRE HAVING A CONFIGURED INTERFERENCE MIRROR AND REFLECTOR

摘要

A LUMINAIRE USING A MULTILAYER INTERFERENCE MIRROR A luminaire is provided which includes a reflector, a light source and a multilayer interference mirror. The light source is selected to emit monochromatic light. The multilayer interference mirror is disposed in a path of light emitted from the light source and is designed for angularly selecting a portion of the light arriving from a multiplicity of directions for passage into a control range. Such a luminaire is useful in illuminating such task areas as parking lots and has particular application for roadway lighting. In particular applications, such as for roadways, a reflector has 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.
