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 the one connector at least partially defines an assembled orientation of the illumination assembly and mounting assembly.

Claims

1. A light fixture assembly comprising:

an illumination assembly including a light generating structure and electrical control circuitry connected to said light generating structure,

a mounting assembly connecting in supporting, heat transferring engagement with said illumination assembly and formed of a material being sufficiently heat conductive to define a heat sink for said illumination assembly,

said mounting assembly having an enlarged exterior surface extending outwardly from and in spaced relation to said illumination assembly, said exterior surface area being exposed to an area being illuminated by said illumination assembly,

a conductor assembly comprising at least one connector connected to a source of electrical energy and formed of an electrically conductive material,

said at least one connector disposed in electrically interconnecting, current conducting relation between the source of the electrical energy and said illumination assembly,

said at least one connector disposed in mechanically interconnecting position between said mounting assembly and said illumination assembly, and

said mounting assembly disposed in electrically segregated relation to said at least one connector and in heat dissipating relation to said illumination assembly.

2. A light fixture assembly as recited in claim 1 wherein said segregating relation is at least partially defined by insulation, formed of a non-electrically conductive material, disposed between said one connector and said mounting assembly.

3. A light fixture assembly as recited in claim 2 wherein said light generating structure comprises at least one LED.

4. A light fixture assembly as recited in claim 3 wherein said at least one connector is disposed in current conducting relation to said at least one LED via said control circuitry.

5. A light fixture assembly as recited in claim 4 wherein said at least one LED is disposed in heat transferring relation to said mounting assembly.

6. A light fixture assembly as recited in claim 5 wherein said control circuitry is disposed in heat transferring relation to said mounting assembly.

7. A light fixture assembly as recited in claim 6 wherein said control circuitry comprises a printed circuit structure.

8. A light fixture assembly as recited in claim 7 wherein said printed circuit structure is disposed in heat transferring relation to said mounting assembly.

9. A light fixture assembly as recited in claim 2 wherein said light generating structure is disposed in heat transferring relation to said mounting assembly.

10. A light fixture assembly as recited in claim 2 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.

11. A light fixture assembly as recited in claim 10 wherein said insulation comprises at least one bushing formed of a non-electrically conductive material and disposed in surrounding relation to said one connector.

12. A light fixture assembly as recited in claim 10 wherein said assembled orientation comprises said illumination assembly and said mounting assembly disposed in heat transferring, confronting engagement with one another.

13. A light fixture assembly as recited in claim 10 wherein said insulation is disposed in an electrically segregating position between said at least one connector and said mounting assembly when in said assembled orientation.

14. A light fixture assembly as recited in claim 2 wherein said insulation assembly comprises at least one bushing formed of a non conductive material and disposed in surrounding relation to said one connector.

15. A light fixture assembly comprising:

an illumination assembly including a light generating structure and electrical control circuitry connected to said light generating structure,

a mounting assembly connecting in supporting, heat transferring engagement with said illumination assembly and formed of a material being sufficiently heat conductive to define a heat sink for said illumination assembly,

said mounting assembly having an enlarged exterior surface extending outwardly from and in spaced relation to said illumination assembly, said enlarged exterior surface area being exposed to an area being illuminated by said illumination assembly,

a cover structure formed of a heat conductive material and connected in heat transferring engagement with said mounting assembly and in heat transferring relation to said illumination assembly,

said at least one connector disposed in electrically interconnecting, current conducting relation between the source of the electrical energy and said illumination assembly,

said at least one connector disposed in a mechanically interconnecting position between said mounting assembly and said illumination assembly, and

said mounting assembly disposed in electrically segregated relation to said at least one connector and in heat dissipating relation to said illumination assembly.

16. A light fixture assembly as recited in claim 15 wherein said mounting assembly is disposed in an at least partially surrounding, predetermined spaced relation to said one connector, said spaced relation defining an air gap disposed and dimensioned to define said electrically segregated relation between said mounting assembly and said one connector.

17. A light fixture assembly as recited in claim 16 wherein said dimension of said air gap between said one connector and said mounting assembly is at least partially determined by the voltage of the electrical energy passing through said one connector to said illumination assembly being sufficient to operate said light generating structure.
