DIRECT-INDIRECT LUMINAIRE HAVING CONFIGURABLE PLANAR LIGHT PANELS

摘要

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.

1. A luminaire comprising
at 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, and a 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.
