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.
