Parabolic troffer-style light fixture
First Claim
1. A light fixture, comprising:
- a fixture housing defining an open end;
a back surface in said housing opposite said open end;
at least one functional louver between said back surface and said open end, said functional louver comprising side reflective surfaces and a mount surface facing toward said back surface;
at least one light source on said mount surface; and
a retention clip on said mount surface, wherein said retention clip is configured to mate with one or more features on said mount surface.

Abstract
A parabolic troffer-style light fixture. The fixtures are sized to fit in, mount to, or suspend from a ceiling, such as being mounted in a conventional ceiling T-grid, for example. The fixture comprises a troffer housing that may be sized to fit in or rest on the T-grid, with the housing having a shape and size similar to those used for conventional fluorescent troffer lighting fixtures. The fixtures comprise a plurality of reflective louvers arranged in a grid that divides the fixture open end into a number of fixture regions with at least one functional louver providing a back side mount surface for light sources, for example, light emitting diodes. The functional louver mount surface faces a reflective back surface designed to redirect impinging light out of the fixture and into the lighted area.
