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.

First claim

What is claimed is:

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.

2. The illumination device of claim 1 , further comprising:
a second luminaire module arranged in the enclosure and configured to output light in a second output angular range, wherein the light output in the second output angular range has a prevalent propagation direction with a component in the first direction towards a second target area,
the second luminaire module comprising:
second LEEs distributed along the second direction, the second LEEs configured to emit light in a second emission angular range;
second primary optics coupled with the second LEEs and configured to redirect light emitted by the second LEEs as redirected light in a second collimated angular range;
a second solid light guide elongated along the second direction and disposed between the second primary optic and a second secondary optic, the second solid light guide configured to receive the redirected light and guide at least some of the received light along the first direction and provide the guided light at a distal end of the second solid light guide to the second secondary optics; and
the second secondary optic elongated along the second direction and comprising a second redirecting surface and a second output surface, the second redirecting surface arranged and configured to reflect the guided light received from the second solid light guide as reflected light in a second reflected angular range, and the second output surface arranged and configured to transmit the reflected light and to output the transmitted light towards the second target area.

3. The illumination device of claim 2 , wherein the first and second LEEs are powered independently.

4. The illumination device of claim 2 , wherein the first output angular range and the second output angular range are mirror symmetrical with respect to a plane parallel to and between the first and second faces of the panel.

5. The illumination device of claim 1 , wherein
the first luminaire module further outputs light in a second output angular range, wherein the light output in the second output angular range has a prevalent propagation direction with a component towards a second target area, and
the first secondary optic of the first luminaire module further comprises a second redirecting surface and a second output surface, the second redirecting surface arranged and configured to reflect the light received from the first primary optics as reflected light in a second reflected angular range, and the second output surface arranged and configured to refract the reflected light and to output the refracted light towards the second target area.

6. The illumination device of claim 1 , wherein
the first face of the panel comprises a first aperture located proximate a distal end of the panel with respect to a portion of the mount along the second direction, and
the light that is output by the first luminaire module passes through the first aperture towards the first target area.

7. The illumination device of claim 6 , wherein the first aperture is elongated along the second direction.

8. The illumination device of claim 6 , wherein the first aperture comprises a glass cover.

9. The illumination device of claim 2 , wherein the second face of the panel comprises a second aperture located proximate a distal end of the panel with respect to a portion of the mount along the second direction, wherein the light that is output in the second output angular range passes through the second aperture towards the second target area.

10. The illumination device of claim 1 , wherein a thickness of the panel is smaller than each of the second direction and the first direction of the first and second faces.

11. The illumination device of claim 1 , wherein the panel is at least a portion of one of a cubical wall, a desk partition, a room partition, a wall panel, or an element of a piece of furniture.

12. The illumination device of claim 1 , wherein a portion of the mount is configured to couple to at least one element for separating spaces along the second direction.

13. The illumination device of claim 12 , wherein the illumination device is detachable from adjacent elements for separating spaces.

14. The illumination device of claim 1 , wherein a portion of the mount is configured to couple to a top of an element for separating spaces.

15. An illumination device comprising:
a mount;
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 plurality of luminaire modules arranged in the enclosure, each luminaire module being configured to output light in a prevalent propagation direction with a component towards a respective target area,
each luminaire module comprising:
a plurality of light-emitting elements (LEEs) distributed along the second direction, the plurality of LEEs being configured to emit light;
one or more primary optics coupled with one or more corresponding LEEs of the plurality of LEEs and configured to redirect light emitted by the one or more corresponding LEEs as redirected light;
