Abstract

A modular track light emitting diode (LED) lighting assembly is provided for improved product lighting in display cases, including refrigeration applications. The modular track LED lighting assembly has a series of LED, including one or more flat LED arranged at an angle to form a lighting spine. In a specific inventive embodiment, the one or more flat LED are arranged at a forty five degree angle. Embodiments of the modular track LED lighting assembly may be configured with a single sided series of light sources or single lighting spine for installation on corners or shelves, or with a double sided series of light sources or lighting spines for mounting on mullions between doors of a display cabinet. The lighting assembly may be powered via battery, or via an alternating current (AC) source that is converted to a direct current (DC) voltage.

Claims

1. A modular track lighting assembly for display cases comprising:

an elongated support structure that encloses a printed circuit board;

one or more lighting spines supported at an angle by said elongated support structure, where the lighting spines face away from each other;

one or more light emitting diodes (LED) individually mounted at a second angle on said one or more lighting spines;

a set of mounting brackets joined to said elongated support;

one or more lenses enclosing said one or more lighting spines;

a pair of end caps at opposing ends of said modular track lighting assembly that seal said assembly; and

wherein said printed circuit board is in electrical communication with said lighting spines.

2. The modular track lighting assembly of claim 1 wherein said elongated support structure is made of metal, plastic, or a composite material.

3. The modular track lighting assembly of claim 1 wherein said printed circuit board distributes power to said one or more lighting spines where the power is supplied by on-board batteries.

4. The modular track lighting assembly of claim 1 wherein said printed circuit board distributes power to said lighting spines where the power is supplied by an AC to DC converter.

5. The modular track lighting assembly of claim 1 wherein said lighting spines are supported at an angle of between thirty and sixty degrees by said elongated support structure.

6. The modular track lighting assembly of claim 1 wherein said lighting spines are supported at an angle of thirty five to sixty degrees by said elongated support structure.

7. The modular track lighting assembly of claim 1 wherein said one or more LED are flat LED.

8. The modular track lighting assembly of claim 1 wherein said second angle is 45 degrees.

9. The modular track lighting assembly of claim 1 wherein said one or more lenses are clear, colored, or opaque.

10. The modular track lighting assembly of claim 1 wherein said one or more lenses are curved or straight surfaces.

11. The modular track lighting assembly of claim 1 wherein said display cases are refrigeration units.

12. The modular track lighting assembly of claim 1 configured as a single sided series of light sources comprising a single lighting spine of said one or more lighting spines for installation on corners or shelves of said display cases.

13. The modular track lighting assembly of claim 1 configured as a double sided series of light sources comprising two lighting spines of said one or more lighting spines each supported at an opposing angle by said elongated support structure, where the lighting spines face away from each other;

and

wherein said double sided series of light sources is designed for mounting on mullions of said display cases.
