Troffer-style light fixture with cross-lighting
First Claim
1. An 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 and, wherein the at least two LED modules include a retention wall extending from a body of the LED modules and the retention wall includes two module slots such that a portion of at least one of the back plate and the side walls is able to extend into one of the two module slots to thereby releasably secure the at least two LED modules to the troffer.

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 an 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, and wherein the at least two LED modules include a retention wall extending from a body of the LED modules and the retention wall includes two module slots such that a portion of at least one of the back plate and the side walls is able to extend into one of the two module slots to threby releasably secure the at least two LED modules to the troffer. - View Dependent Claims (11, 12, 13, 14, 15, 16)
