ABSTRACT:
The present invention relates to a luminaire and more particularly a downlight for industrial lighting applications. Energy considerations, lowered ceiling heights, and greater demand for illumination uniformity has resulted in a demand for a versatile and efficient downlight. The present invention anticipates providing a reflector, lamp, and refractive lens construction which utilizes an incrementally painted reflective surface to provide a versatile spacing between each downlight in an array, using the same basic downlight configuration. The refractive lens includes prismatic refractor elements which reshape the downwardly directed conical beam of light to provide even more uniform illumination when used in conjunction with the plurality of such downlights arrayed in an industrial lighting situation.
