Aug 1, 2008

Appl. No.:

12/185005

Inventors:

Douglas Grove - Tupelo MS, US

International Classification:

F21V 29/00

US Classification:

362294

Abstract:

An LED light fixture with enhanced thermal management. The fixture may be in a surface-mounted or a recessed configuration. The LED is attached with thermally-conductive material, such as thermal transfer tape, to a heat sink or housing. The heat sink may comprise a number of cooling fins to radiate heat, as well as a number of openings to promote cooling air flow. A variety of reflector assemblies can be used for different optical and aesthetic configurations. One or more lenses may be used.

International Classification:

F21V 7/00

US Classification:

362241

Abstract:

A light engine that includes light emitting diodes mounted on a printed circuit board, which in turn is attached to a heat sink. An optic assembly is positioned over the printed circuit board to direct the emitted light as desired. The light engine can be positioned. within the ceiling within the opening of a mounting frame. In some embodiments, the light engine is retained on the mounting frame such that it can be moved clear of the mounting frame opening.

International Classification:

F21S 9/02
F21S 8/02
F21V 23/00

Abstract:

A light fixture may include a light fixture housing defining an internal cavity. A light fixture may also include one or more light engines positioned within the internal cavity of the light fixture housing and designed to emit light for illumination. A light fixture may also include an external power driver positioned within the internal cavity of the light fixture housing and designed to receive power from an external power source, and provide power to and control the one or more light engines. A light fixture may also include a backup power supply positioned within the internal cavity of the light fixture housing, and a backup power driver positioned within the internal cavity of the light fixture housing and designed to receive power from the backup power supply, and provide power to and control the one or more light engines.

Inventors:

- Atlanta GA, US
Douglas Dewayne Grove - Grayson GA, US
Bruce Layne - Wheaton IL, US

International Classification:

F21V 21/28
F21S 8/00
F21V 23/00

Abstract:

A wall-mounted lighting fixture includes a mounting plate, a canopy and an aiming assembly. The canopy is secured to a mounting plate mounted to a wall. The aiming assembly includes a disk, a tilting assembly, and a light emitting assembly. The canopy defines a circular recess which the disk is positioned flush within. The tilting assembly is coupled to the disk and the light emitting assembly, and includes a pivot joint, for example a hinge, allowing the light emitting assembly to tilt relative to the disk. The disk is rotatably coupled to the canopy allowing the light emitting assembly to rotate relative to the canopy, and therefore the wall. The tilting and rotation allow emitted light from the light emitting assembly to be aimed in two degrees of freedom.

Daniel Aaron Weiss - Tucker GA, US

International Classification:

F21V 15/01
F21V 21/14
F21V 15/015
F21S 8/02

Abstract:

A light fixture includes a flexible shroud, an outer housing, and a light source within a light engine. The light engine couples within the outer housing so as to define a gap between the light engine and an inner perimeter of the outer housing. The flexible shroud forms at least first and second edge portions. The light engine couples with the first edge portion, and the inner perimeter of the outer housing couples with the second edge portion, so that the flexible shroud covers at least part of the gap. A shroud for a light fixture may include a flexible shroud that defines one or more edges. The shroud may include one or more coupling features along the one or more edges. The flexible shroud may form a thickness variation at the coupling feature, to engage a corresponding coupling feature of a light fixture.

F21V 21/005
F21V 23/02

Abstract:

A light fixture includes a housing having sidewalls that define a manifold aperture, extending from upper to lower edges of the manifold aperture. The housing includes first coupling features. The light fixture includes at least one adapter plate with second coupling features that removably couple with the first coupling features. The adapter plate defines an adapter plate aperture. At least one light emitting engine removably couples with the adapter plate such that emitted light passes through the adapter plate aperture. The light fixture further includes a baffle that includes at least one baffle cell. The baffle cell includes an upper baffle edge that defines: an upper baffle aperture through which light emitted by the light engine passes, a lower baffle edge that defines an output aperture for the emitted light, and a baffle cell wall that extends from the upper baffle edge to the lower baffle edge.
