Abstract

The invention provides an elongated lighting fixture with multiple light emitting diodes (LEDs) arrayed in two groups that are angled to each other. The fixture provides an extremely broad light emitting angle and includes an elongated housing having a pair of side walls with at least one fin to dissipate heat. Each side wall has a support member extending upward at angle from the side wall, wherein the side walls terminate at a central wall. A generally transparent cover is connected to the housing and extends between opposed ends of the housing. A first elongated fastener and a second elongated fastener are utilized to mount a first group of LEDs and a second group of LEDs to the first support member and the second support member, respectively. First and second interconnection board assemblies are affixed to respective support members beneath the group of LEDs by the first and second fasteners. When the first and second interconnection board assemblies are energized by an internal power source, current travels from each interconnection assembly through the fasteners to each group of LEDs for illumination.

Claims28

Dependent claims

A lighting fixture for use in refrigerator coolers or freezers, the lighting fixture comprising:

an elongated external housing securable to an interior of a refrigerated cooler or freezer, the external housing having a first external side wall and a second external side wall wherein each external side wall has at least one heat dissipating fin extending from an external surface of said external side wall, the housing further having a first support member angularly and integrally extending from the first external side wall and a second support member angularly and integrally extending from the second external side wall, wherein the support members terminate at an elevated central wall, and wherein the first and second external side walls, the first and second support members, and the central wall collectively define a U-shaped internal cavity of the housing with an open end configuration opposite the central wall, and wherein the U-shaped internal cavity is enclosed by a removable rear wall extending between a lowermost portion of the first and second external side walls;
a first group of light modules secured to the first support member by a first elongated fastener and a second elongated fastener, each light module comprising a light emitting diode (LED) mounted on a printed circuit board, wherein said elongated fasteners extend through printed circuit board and into the first support member;
and,
a second group of light modules secured to the second support member by a first elongated fastener and a second elongated fastener, each light module comprising a LED mounted on a printed circuit board, wherein said elongated fasteners extend through printed circuit board and into the second support member.

A LED lighting fixture comprising:

an elongated external housing configured to be secured to an interior of a refrigerated cooler or freezer, the external housing having a first external side wall and a second external side wall, wherein a first support member extends upwardly from an uppermost end of the first external side wall and a second support member extends upwardly from an uppermost end of the second external side wall, and wherein the first and second support members converge at an elevated central wall that resides above the uppermost end of the first and second side walls, wherein the first and second external side walls, the first and second support members, and the central wall collectively define a U-shaped internal cavity of the housing with an open end configuration opposite the central wall;
a first group of light modules secured to an outer surface of the first support member, each light module comprising a light emitting diode (LED) mounted on a printed circuit board;
a second group of light modules secured to an outer surface of the second support member, each light module comprising a LED mounted on a printed circuit board;
and,
a cover that extends between opposed ends of the housing, the cover having opposed side segments, each segment having a tongue that is received by a recess at an uppermost end of each of the first and second external side walls of the housing.
