SPLIT BEAM LUMINAIRE AND LIGHTING SYSTEM
First Claim
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, whereinthe 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; and
a 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.

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.

14. A lighting system for an office space, comprising:
-
a plurality of luminaires, each 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, and an 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 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, reflecting at least a first 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; and a control unit adapted to acquire a task and background area lighting level configuration for the office space, and to control the one or more first light sources and the one or more second light sources of each of the plurality of luminaires such that a total illumination pattern produced by the plurality of luminaires corresponds to the task and background area lighting level configuration for the office space. - View Dependent Claims (15)
