Filed:

Feb 14, 2011

Appl. No.:

13/026957

Inventors:

Robert Allan Blalock - Peachtree City GA, US
George Michael Drake - Newnan GA, US

Assignee:

Cooper Technologies Company - Houston TX

International Classification:

F21V 3/00
F21V 29/00
F21V 19/00

US Classification:

362294, 362646, 36231102, 36231114, 362373

Abstract:

A LED holder includes a planar base member to releasably couple the holder to the heat sink of a luminaire. The LED holder also includes a substrate that is coupled to the planar base member and has one or more LEDs disposed on the substrate and electrically coupled to the substrate. The substrate can be a printed circuit board and the LEDs can be discrete LEDs or an LED package. A cover panel is removably coupled to the planar base member and is designed to prevent access to the substrate and the LEDs when the luminaire powered on. The LED holder can also include a LED cover positioned over the LEDs and within the cover panel to limit access to the top side of the LEDs while permitting light emitted by the LEDs to pass through the LED cover.

Abstract:

An LED downlight provides a more evenly distributed light output. The LED downlight includes an LED light source, such as one or more LEDs, LED die packages, or LED chip on board modules, an upper reflector, a lower reflector disposed below the upper reflector, and a lens disposed between the upper reflector and the lower reflector. The lens includes several features that help disperse light emitted by the LED light source. The lens includes a diffusion element, such as a pigment, bulk scattering, prismatic, inlays, or another method for diffusing light through a lens. The lens is curved in a concave manner when viewed from the light source. The curve of the lens can be tangent to the physical cutoff of the lower reflector to more evenly distribute light emitted by the LED light source and to improve the visual effect of an evenly luminous lens.

Abstract:

A lamp subassembly includes an air-tight plate, a mounting lamp holder coupled to the air-tight plate, and a mounting spring coupled to the air-tight plate and the mounting lamp holder. The lamp subassembly is coupled to a trim with the mounting spring and coupled to a lamp with the mounting lamp holder to form a lighting fixture. The air-tight plate is coupled to a top opening located on the trim and forms an air-tight interface therebetween. The mounting lamp holder positions the lamp at least partially within the trim. The air leakage through the air-tight interface is equal to or less than two cubic feet per minute at a seventy-five Pascal pressure difference.
