US Patent 10514139 LED fixture with integrated driver circuitry

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.
