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.

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. 11. The refrigerated cooler of claim 8, wherein each module includes three first side apertures and three second side apertures. 12. The refrigerated cooler of claim 8, wherein each module has an octagonal configuration with eight sides arranged substantially in a plane defined by the light engine. 13. The refrigerated cooler of claim 8, wherein the light engine includes a linear current regulator, a protective diode, a ballast resistor, a transient voltage suppressor and an insulation displacement connector. 14. The refrigerated cooler of claim 8, wherein each module includes a gasket positioned within the housing and external to the receiver of the housing. 15. The refrigerated cooler of claim 11, wherein the first group of side-emitting LEDs comprises seven side-emitting LEDs associated with the three first side apertures, and the second group of side-emitting LEDs comprises seven side-emitting LEDs associated with the three second side apertures.
