Abstract

A system of scalable modular LED light fixtures is provided herein for accommodating different levels of generated lighting and to accommodate different mountings.

Claims

1. A system for preparing scalable, variable-mounting LED lighting fixtures, the system comprising:

at least one front end cap;

at least first and second rails;

at least one LED light module;

at least one housing cover; and

,

a set of back ends, each said back end of said set of back ends being differently configured for different mountings,

wherein, depending on a selected number of said LED light modules, a length of each of said first rail, said second rail and said housing cover is adjusted, and

wherein, said length-adjusted front rail, said length-adjusted second rail and said length-adjusted housing cover are disposed to extend between said front end cap and a selected one of said back ends from said set of back ends so as to define a volume for accommodating said selected number of said LED light modules.

2. A system as in claim 1, wherein said first and second rails are spaced-apart and generally parallel.

3. A system as in claim 1, wherein said first rail has a constant cross-section along the length thereof.

4. A system as in claim 3, wherein said second rail has a constant cross-section along the length thereof.

5. A system as in claim 1, wherein each said LED light module includes a base and a plurality of LED light elements fixed thereto.

6. A system as in claim 1, further comprising a heat dissipation element located between said selected number of said LED light modules and said length-adjusted housing cover.

7. A system as in claim 6, wherein said heat dissipation element includes a plurality of spaced-apart fins.

8. A system as in claim 6, wherein said heat dissipation element is formed integrally with said first rail and with said second rail.

9. A system as in claim 1, wherein said different mountings include trunnion mounting, tennon mounting, slip fitter mounting, rigid surface mounting, adjustable surface mounting, pole mounting, wall mounting, and canopy mounting.

10. A system as in claim 1, wherein each said back end of said set of back ends includes a similarly-configured rear end cap.

11. A system for preparing scalable, variable-mounting LED lighting fixtures, the system comprising:

at least one front end cap;

at least first and second rails;

at least one LED light module;

at least one housing cover;

a first back end with a trunnion mounting element;

a second back end with a tennon mounting element;

a third back end with a slip fitter mounting element; and

a fourth back end with a surface mounting element,

wherein, depending on a selected number of said LED light modules, a length of each of said first rail, said second rail and said housing cover is adjusted, and

wherein, said length-adjusted first rail, said length-adjusted second rail and said length-adjusted housing cover are disposed to extend between said front end cap and a selected one of said first back end, said second back end, said third back end, and said fourth back end, so as to define a volume for accommodating said selected number of said LED light modules.

12. A system for preparing scalable, variable-mounting lighting fixtures, the system comprising:

at least one front end cap;

at least first and second rails of different lengths;

at least one LED light module;

at least one housing cover; and

,

a set of back ends, each said back end of said set being differently configured for different mountings,

wherein, depending of a selected number of said LED light modules, selecting one of said first rails and one of said second rails; and

wherein, said selected front rail, said selected second rail and said selected housing cover are disposed to extend between said front end cap and a selected one of said back ends so as to define a volume for accommodating said selected number of said LED light modules.
