TROFFER-STYLE LIGHT FIXTURE WITH CROSS-LIGHTING
First Claim
1. A LED-based light fixture, comprising:
- a troffer comprising;
a back plate;
side walls extending from a periphery of the back plate; and
at least two receptacles positioned apart from each other, the at least two receptacles coupled to at least one of the back plate and the side walls; and
at least two LED modules, wherein the LED modules are retained by the at least two receptacles such that light emitted by each of the at least two LED modules is substantially oriented toward another of the at least two LED modules.

Abstract
This is directed to a troffer-style light fixture using a LED light to cross-light internal surfaces of the troffer. In particular, this is directed to a troffer-style fixture having several receptacles for receiving LED modules. The modules can be inserted in the fixture such that some light emitted by the LED modules is directed towards an opposite surface of the fixture, causing light from opposite LED modules to mix as light is emitted from the fixture (e.g., cross lighting the fixture environment. The resulting light transmitted and reflected by the troffer can have softer qualities than direct light emitted by a LED module, and enhance the aesthetic appeal of light provided by the fixture. In some embodiments, one or more optical treatments can be applied to internal surfaces of the fixture to enhance the light output by the fixture.

10. A method for constructing a LED-based light fixture, comprising:
-
defining a troffer comprising a back plate and side walls defining an internal volume; and coupling at least two LED modules to the troffer, wherein the at least two LED modules direct light out of the internal volume such that at least a substantial portion of the light directed by each of the at least two LED modules intersects before reaching a distance of 6 vertical feet from the troffer. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A troffer-style light fixture, comprising:
-
a rectangular back plate a side wall extending around a periphery of the back plate, the side wall comprising distinct segments extending from each side of the rectangular back plate; and at least two slots extending through a surface of the side wall, wherein the at least two slots extend from segments of the side wall that are not adjacent, wherein; the at least two slots are operative to each receive a retention wall of a LED module inserted in the slot such that light emitted by the LED module is substantially directed towards a region out of a volume enclosed by the light fixture, the region adjacent to the side wall segment opposite the side wall segment comprising the slot receiving the LED module. - View Dependent Claims (18, 19, 20, 21)
