Filed:

Feb 2, 2012

Appl. No.:

13/365180

Inventors:

Paul Kenneth Pickard - Morrisville NC, US
Elizabeth Ann Rodgers - Raleigh NC, US

International Classification:

F21V 29/02
F21V 21/03
F21V 29/00
F21V 5/04
F21S 4/00
F21V 7/00

US Classification:

362218, 36224901, 362241, 362237, 362297

Abstract:

A modular lighting fixture assembly. Multiple light pods can be removably mounted on both lateral sides of a mechanical thermal element, such as an elongated heat sink. The pods can be easily removed for cleaning, maintenance, and transport, for example. A light strip including multiple LEDs can be mounted to a surface of the heat sink on both sides. Each pod has a portion cutaway such that when the pods are mounted to the heat sink, the cutaway portions align with the light strips. Thus, when mounted, the light strip can be adjacent to or protrude into an interior cavity of the pod. The interior surfaces of the pods are shaped to redirect light in a particular output profile. The assembly may be mounted to a ceiling and used as an overhead fixture designed to efficiently light an aisle in a retail space or a storage facility, for example.

International Classification:

F21V 29/00
F21V 13/04
F21V 7/00

US Classification:

362218

Abstract:

A direct lighting fixture that is well-suited for use with solid state light sources, such as LEDs, and particularly useful for lighting aisles in commercial and industrial environments. An elongated housing comprises several integral elements including a heat sink, opposing side reflectors, and a mount surface. A plurality of light sources is disposed on the mount surface. Each light source or cluster of sources has an optical element such as a lens over it to redirect a portion of the light emitted from the sources in a desired direction, for example, to collimate the light. Reflective elements are placed on both sides of each light source or cluster to redirect light that is initially emitted in a longitudinal direction. The fixture may comprise multiple elongated housings connected together and aligned in parallel along the longitudinal direction. The fixture may also be scalable.

International Classification:

F21K 99/00

US Classification:

362 84, 36231102

Abstract:

A lamp comprises an optically transmissive enclosure and a base. An LED assembly is located in the enclosure and is operable to emit light when energized through an electrical path from the base. The LED assembly comprises an LED and a lumophoric dome that surrounds the LED. A partially reflective pad is on the lumophoric dome for manipulating the pattern of light emitted from the lumophoric dome. A heat sink comprises a heat dissipating portion that is at least partially exposed to the ambient environment and a heat conducting portion that is thermally coupled to the LED. An optically transmissive lens emits light from the enclosure where the lens comprises an annular area defined by a textured surface and a transparent area interior of the annular area.
