US 12,618,615 B2 · LED lighting array system for illuminating a display case

Abstract

An LED lighting array system includes discrete lighting modules spatially arrayed along a support member to provide illumination of items within a display case. The modules have a low overall height that results in them being mounted in a low-profile configuration at various locations along the support member. The modules include a housing with opposed first and second sets of side apertures, a plurality of internal reflecting surfaces associated with the apertures, respectively, an external lens, a multi-sided light engine and a group of side-emitting LEDs. During operation, a first portion of light generated by the side-emitting LEDs is discharged through apertures and the lens into the cooler to illuminate contents therein, while a second portion of light generated by the side-emitting LEDs is redirected by the reflecting surface through said apertures and the lens into the cooler.

Dependent claims

A lighting array system featuring light emitting diodes (LEDs) for use within a refrigerated cooler to illuminate products residing within the refrigerated cooler, the lighting array system comprising:

a first module comprising:
a first LED,
a first reflecting surface, and
a first transparent external lens configured to substantially overlie the first LED and the first reflecting surface, the first external lens having:
a first external wall having a first external surface,
a second external wall having a second external surface, and
an intermediate wall that extends between and connects the first and second external walls, wherein the intermediate wall has an outer surface, and wherein the entirety of the outer surface is not positioned perpendicular to the first external surface of the first external wall or the second external surface of the second external wall;
and
wherein during operation of the lighting array system, a first portion of light generated by said first LED is discharged in a first direction through the first external lens, and a second portion of light generated by said first LED is redirected by the first reflecting surface through the first transparent external lens.

6 more elements

A refrigerated cooler that displays products residing within the refrigerated cooler, the refrigerated cooler comprising:

a lighting array system installed within the refrigerated cooler and including:
a support member configured to be coupled to an internal structure within the refrigerated cooler, said support member including a first aperture and a second aperture that are formed through the support member and that are spaced an appreciable distance apart along a length of the support member;
a first module received within the first aperture and having:
a first LED, and
a first external lens configured to overlie the first LED and a first reflecting surface, the first external lens having:
a first external wall having a first external surface, a second external wall having a second external surface, and an intermediate wall that extends between and connects the first and second external walls, wherein the intermediate wall has an outer surface, and wherein the entirety of the outer surface is not positioned perpendicular to the first external surface or the second external surface;
a second module received within the second aperture and having:
a second LED, and
a second external lens configured to overlie the second LED;
wherein an intermediate extent of the support member is defined along said length of the support member between the first and second modules, said intermediate extent being exposed without an overlying lens to an inner portion of the refrigerated cooler.
