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.

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. 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 group of LEDs and a second group of LEDs are mounted to the first support member and the second support member, respectively. PCB boards assemblies are affixed to respective support members beneath the group of LEDs by tension clips. When the PCBs are energized by a power source, current travels from the PCBs to each LED for illumination.

Abstract: The invention relates to a refrigerated display case with an illuminated support member or “mullion” that efficiently transfers heat generated by at least one light emitting diode (LED) to warm and maintain door seals. The invention further relates to a low-profile, elongated LED light fixture that is retrofitted to the display case mullion to provide efficient illumination. The LED light fixture includes an elongated frame having a central hub extending longitudinally along the frame. A pair of opposed arms extending upwardly at an angle from the central hub, wherein the terminus of each arm has a curvilinear configuration that defines a receiver. At least one leg extends rearward from the central hub. Two legs are spaced a distance apart to define an elongated central cavity that that receives a fastener for securement of the fixture to the vertical support within the display case.

Abstract: The present invention provides a multi-adjustable LED luminaire having an integrated active cooling system to minimize heat buildup and increase operating performance. The multi-adjustable LED luminaire can have a generally cylindrical configuration, or a generally spherical configuration, and is operably connected to an elongated track that supplies power to the luminaire. The LED luminaire includes an upper housing segment having a power supply, and a lower housing segment that includes the active cooling system and an LED light engine coupled to a heat sink. The active cooling systems draws ambient air into a rearward portion of the housing and forces air over the heat sink and LED light engine. A power distribution PCB of the cooling system monitors the temperature of the heat sink and can adjust power delivery to the LED based upon the temperature.

Abstract: The invention provides a light fixture that includes a light engine, a rugged housing, and an internal power module that is thermally isolated. The light fixture includes several novel heat management features designed to thermally isolate the power supply in order to reduce the risk of failure and thereby increase the reliability of the light fixture. The light engine includes groups of light modules, each having a light emitting diode (LED) and a zener diode. The power module resides within a rear receptacle of the housing and includes a power supply, a box, and a cover that enclose the power supply. The housing also includes an arrangement of external fins that dissipate heat generated by the light engine. During operation, heat is generated by the light modules, namely the LEDs, and then is transferred along a flow path through a main body portion of the housing and the fins for dissipation to ambient without negatively impacting the power supply.
