Split beam luminaire and lighting system
First Claim
1. A luminaire comprising:
- a plurality of first light sources, wherein each of the first light sources includes a first light emitter and an associated first beam optics, and each of the first light sources configured to emit, using the first beam optics, a first light beam of a first beam pattern having a first angular intensity distribution;
a plurality of second light sources, wherein each of the second light sources includes a second light emitter and an associated second beam optics, and each of the second light sources configured to emit, using the second beam optics, a second light beam of a second beam pattern having a second angular intensity distribution,wherein each of the first and second pluralities of light sources are independently controllable, andan optical axis of the each first light beam is parallel to an optical axis of the each second light beam; and
a chamber encompassing the first light sources and the second light sources, the chamber comprising one or more outer side walls and an exit window,wherein the one or more outer side walls comprise sections which are specularly reflective and section which are partially specularly transmitting, and are 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 each first light beam and the optical axis of each second light beam.

Abstract
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.
