LED fixture with integrated driver circuitry

摘要

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.

主权项

1. A lighting device, comprising:
a housing comprising: a base; an open end opposite said base; an exterior surface; and an interior surface of said housing opposite said exterior surface and shaped to define an internal optical chamber, at least a portion of said interior surface being reflective and shaped to redirect light out of said open end; at least one LED in said internal optical chamber; and a reflector cone in said internal optical cavity chamber, said reflector cone shaped to define a hole that aligns with said at least one LED; wherein at least some light from said at least one LED is reflected by an interior surface of said reflector cone and said interior surface of said housing.
