SPLIT BEAM LUMINAIRE AND LIGHTING SYSTEM

摘要

The invention relates to a luminaire and a lighting system. The luminaire includes first and second light sources adapted to emit light beams of two different beam patterns encompassed within a single chamber with specular outer walls that are parallel to the optical axis of the beam patterns of both types of light sources. Employing a chamber having specular outer walls aligned with the optical axis of the beam patterns of both types of light sources and adapted to specularly reflect at least a portion of light incident thereon allows more uniform appearance of the luminaire while preserving the respective total beam patterns of the beams produced by the first and second light sources as the light beams are incident on the exit window of the chamber.

主权项

1. A luminaire comprising:
one or more first light sources, each of the one or more first light sources configured to emit a first light beam of a first beam pattern; one or more second light sources, each of the one or more second light sources configured to emit a second light beam of a second beam pattern, wherein
the second beam pattern is different from the first beam pattern, andan optical axis of the each first light beam is parallel to an optical axis of the each second light beam; anda chamber encompassing the one or more first light sources and the one or more second light sources, the chamber comprising one or more outer side walls and an exit window, wherein the one or more outer side walls are substantially specular, adapted to reflect at least a portion of light incident thereon to be incident onto the exit window, and are substantially parallel to the optical axis of the each first light beam and the optical axis of the each second light beam; said outer side walls comprise sections which are partially specularly reflective and partially transmitting.
