Illumination devices including enclosure panels with luminaire modules
First Claim
1. An illumination device comprising:
- amount;
a panel comprising a first face and a second opposing face forming an enclosure, the first and second faces extending in a first direction and a second direction perpendicular to the first direction, wherein, when mounted to a floor, the mount supports the panel so that the first direction is a vertical direction and the second direction is a horizontal direction; and
a first luminaire module arranged within the enclosure and configured to direct light from the panel in a first output angular range, wherein the light in the first output angular range has a prevalent propagation direction with a component in the first direction towards a first target area,the first luminaire module comprising;
first light-emitting elements (LEEs) distributed along the second direction, the first LEEs configured to emit light in a first emission angular range;
first primary optics coupled with the first LEEs and configured to redirect light emitted by the first LEEs as redirected light in a first collimated angular range;
a first solid light guide elongated along the second direction and disposed between the first primary optic and a first secondary optic, the first solid light guide configured to receive the redirected light and guide at least some of the received light along the first direction of the first solid light guide and provide the guided light at a distal end of the first solid light guide to the first secondary optic; and
the first secondary optic elongated along the second direction and comprising a first redirecting surface and a first output surface, the first redirecting surface arranged and configured to reflect the guided light received from the first solid light guide as reflected light in a first reflected angular range, and the first output surface arranged and configured to transmit the reflected light and to output the transmitted light towards the first target area.

Abstract
Devices used for workspace illumination include, for example, a panel and a solid-state based optical system arranged inside an enclosure of the panel. The panel can be a cubicle divider. In one aspect, an illumination device includes a mount; a panel including a first face and a second opposing face. The panel is vertically supported by the mount along a horizontal dimension of the first and second faces. Further, the panel forms an enclosure between the first and the second face. Additionally, the illumination device includes a first luminaire module arranged in the enclosure and configured to output light in a first output angular range. The light output in the first output angular range has a prevalent propagation direction with a vertical component towards a first target area.
