Abstract

A light fixture assembly including an illumination assembly in the form of one or more light emitting diodes is interconnected to an electrical energy source by control circuitry. A mounting assembly supports the illumination assembly and a cover structure is disposed in heat transferring relation to the illumination assembly, wherein the cover structure and/or mounting assembly have enlarged surface areas formed of a heat conductive material, facilitating heat dissipation generated by the illumination assembly into the surrounding environment. At least one connector, formed of an electrically conductive material, is disposed in interconnecting, current conducting relation between a source of electrical energy and the illumination assembly. The mounting assembly is disposed in electrically segregated relation to the connector(s), wherein said interconnecting relation of said one connector at least partially defines an assembled orientation of the illumination assembly and mounting assembly.

Claims

6. A light fixture assembly as recited in claim 3 wherein said modular connector assembly comprises a first RJ45 connector having a male configuration connected to a distal end of said Cat 5 cable and a second RJ45 connector having a female configuration attached to said illumination assembly.

7. A light fixture assembly as recited in claim 6 wherein said first and second RJ45 connectors are disposed and structured for removable attachment to one another to at least partially define said current conducting relation between the source of electrical energy and said control circuitry.

8. A light fixture assembly as recited in claim 2 wherein said segregated relation is at least partially defined by insulation, formed of a non-electrically conductive material, disposed between said one connector and said mounting assembly.

9. A light fixture assembly as recited in claim 8 wherein said at least one connector is disposed in current conducting relation to said at least one LED via said control circuitry.

10. A light fixture assembly as recited in claim 9 wherein said at least one LED and said control circuitry are disposed in heat transferring relation to said mounting assembly.

11. A light fixture assembly as recited in claim 8 wherein said at least one connector is disposed in interconnecting relation to said illumination assembly and said mounting assembly, said interconnecting relation at least partially defined by an assembled orientation of at least said illumination assembly with said mounting assembly.
