LED lighting array system for illuminating a display case
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.
1. A light emitting diode (LED) lighting array system for use with at least one support member within a refrigerated cooler to illuminate products residing within the cooler, the LED lighting array system comprising:
at least one LED module configured to be installed within a support member of the cooler, each LED module comprising:
a housing having a first side aperture and a second side aperture in an opposed positional relationship, a first internal reflecting surface extending outward from the first side aperture to a peripheral wall, and a second internal reflecting surface extending outward from the second side aperture to the peripheral wall;
an external lens configured to substantially mate with an upper extent of the housing; and
a light engine positioned within a receiver of the housing, the light engine including a first group of side-emitting LEDs associated with the first side aperture and a second group of side-emitting LEDs associated with the second side aperture,
wherein during operation of the LED lighting array system, a first portion of light generated by said side-emitting LEDs is discharged through said apertures and the lens, and a second portion of light generated by said side-emitting LEDs is redirected by the reflecting surface through said apertures and the lens.
2. The LED lighting array system of claim 1 , further comprising a plurality of LED modules configured to be installed an appreciable distance apart within the support member of the cooler.
3. The LED lighting array system of claim 1 , wherein each of the first and second groups of side-emitting LEDs comprises seven side-emitting LEDs.
4. The LED lighting array system of claim 1 , wherein each LED module includes three first side apertures and three second side apertures.
5. The LED lighting array system of claim 1 , wherein each LED module has an octagonal configuration with eight sides arranged substantially in a plane defined by the light engine.
6. The LED lighting array system of claim 1 , wherein the light engine includes a linear current regulator, a protective diode, a ballast resistor, a transient voltage suppressor and an insulation displacement connector.
7. The LED lighting array system of claim 4 , wherein the first group of side-emitting LEDs is associated with the three first side apertures, and the second group of side-emitting LEDs is associated with the three second side apertures.
8. A refrigerated cooler that displays products residing within the cooler, the cooler having light emitting diode (LED) lighting array system to illuminate products within the cooler, the cooler comprising:
an arrangement of internal support members;
a LED lighting array system installed within the cooler and including:
a first module installed within a support member of the cooler,
a second module installed within said support member a distance from the first module;
said first and second modules each including:
a housing having:
a first side aperture;
a second side aperture in an opposed positional relationship with the first side aperture;
a first internal reflecting surface extending outward from the first side aperture to a peripheral wall;
a second internal reflecting surface extending outward from the second side aperture to the peripheral wall;
a chamber; and
a printed circuit board coupled to the chamber;
an external lens configured to substantially mate with an upper extent of the housing; and
a light engine positioned within a receiver of the housing,
the light engine including a first group of side-emitting LEDs associated with the first side aperture and a second group of side-emitting LEDs associated with the second side aperture;
wherein during operation of the LED lighting array system, a first portion of light generated by said side-emitting LEDs is discharged through said apertures and the lens into the cooler to illuminate the products, and a second portion of light generated by said side-emitting LEDs is redirected by the reflecting surface through said apertures and the lens into the cooler to illuminate the products.
9. The refrigerated cooler of claim 8 , wherein the first group of side-emitting LEDs comprises seven side-emitting LEDs.
10. The refrigerated cooler of claim 8 , wherein the second group of side-emitting LEDs comprises seven side-emitting LEDs.
