DIRECT-INDIRECT LUMINAIRE HAVING CONFIGURABLE PLANAR LIGHT PANELS
First Claim
1. A luminaire comprisingat least two planar light sources having a top light emitting planar surface for producing a characteristic up-light distribution pattern and a bottom light emitting planar surface for producing a characteristic down-light distribution pattern, anda support frame for supporting planar light sources such that each of said light sources can emit up-light and down-light substantially unobstructed by said support frame, said support frame being adapted to allow the planar light sources to be removed and reinstalled in the support frame in a different rotated orientation relative to each other.

Abstract
A direct-indirect luminaire 11 is comprised of a support frame 23, 25 for supporting multiple planar light sources 15 that emit light from both their top and bottom planar surfaces 17, 19 for producing up-light and down-light in characteristic light distribution patterns. The planar light sources, which are preferably edge-fed light waveguides, can be supported in the support frame in different rotational orientations that can be changed to change the light distribution characteristics of the luminaire.

9. A luminaire comprising
an outer support ring, and a plurality of planar light sources having a top light emitting planar surface for producing a characteristic up-light distribution pattern and a bottom light emitting planar surface for producing a characteristic down-light distribution pattern, each of said planar light sources between being supported between said inner and outer support rings at different possible rotated orientations, wherein, when supported between said inner and outer support rings, the support rings and planar light sources form a luminaire with an up-light and down-light distribution pattern the depends on the rotated orientations of the planar light sources supported between said inner and outer support rings.

18. A luminaire comprising
an inner support ring having corner regions and straight wall sections, an outer support ring having corner regions and straight sections corresponding with the corner regions and straight sections of said inner support ring, and wherein straight wall sections of said inner support ring oppose straight wall sections of said outer ring, the corner regions of at least one of said inner and outer support rings including suspension points for the luminaire and points where the luminaire can be wired to an external power source a plurality of planar light sources having a top light emitting planar surface for producing a rotationally asymmetric up-light distribution pattern and a bottom light emitting planar surface for producing a substantially rotationally symmetric down-light distribution pattern, each of said planar light sources between being supported between the straight wall sections of said inner and outer support rings at different possible rotated orientations, wherein, when supported between said inner and outer support rings, the support rings and planar light sources form a luminaire with an up-light and down-light distribution pattern the depends on the rotated orientations of the planar light sources supported between the straight wall sections of said inner and outer support rings.
