LED fixture with integrated driver circuitry
First Claim
1. A solid state light fixture, comprising:
- a solid state lighting housing comprising a base and an interior reflective surface that define an optical chamber with an open end;
a plurality of light emitting diodes within said optical chamber;
a driver circuit within said optical chamber;
a junction box on said housing; and
at least one mounting mechanism operable to releasably mount said fixture in an opening in a ceiling,wherein said mounting mechanism is attached to said fixture between said housing and said junction box; and
wherein said interior reflective surface is positioned to redirect light from said plurality of light emitting diodes out of said open end.

Abstract
A solid state lighting fixture with an integrated driver circuit. A housing has a base end and an open end through which light is emitted from the fixture. The reflective interior surface of the fixture and the base define an optical chamber. At least one, and often multiple, light sources are mounted at the fixture base along with the circuitry necessary to drive and/or control the light sources. The drive circuit and the light sources are both located in the optical chamber. A reflective cone fits within the optical chamber such that it covers most of the drive circuit and other components at the base of fixture that might absorb light. The reflective cone is shaped to define a hole that is aligned with the light sources so that light may be emitted through the hole toward the open end of the fixture.
