Composite luminaire

1. A luminaire comprising:

a core made up of a first material;

an LED lighting arrangement mounted to the core; and

a housing made up of a second material, the second material being different from the first material, the housing including:

a central part having a recess in which the core is received,

a finned part including a plurality of fins that extend radially from the central part, and

a fence part, the fence part being spaced from the central part so as to create a space therebetween, the fence part interconnecting adjacent fins to one another.

2. The luminaire of claim 1 , wherein the plurality of fins are arranged so that a periphery of the finned part forms a substantially circular shape.

3. The luminaire of claim 1 , wherein the plurality of fins are arranged so that a periphery of the finned part forms a substantially square shape.

4. The luminaire of claim 1 , wherein the core includes a plurality passageways extending through the core.

5. A method of manufacturing a luminaire comprising the steps of:

forming a core from a first material, the core having a first width corresponding to an exterior dimension of the core;

forming a housing from a second material different from the first material, the housing including a recess, the recess having a second width corresponding to an interior dimension of the recess, the second width being less than the first width;

creating a temperature differential between the first material and the second material;

introducing the core into the recess to secure the core to the housing; and

securing an LED lighting arrangement on the core.

6. The method of manufacturing a luminaire according to claim 5 , wherein the step of creating a temperature differential includes heating the core.

7. The method of manufacturing a luminaire according to claim 6 , wherein the core is heated to a temperature that is below the melting point of the first material, but above the melting point of the second material.

8. The method of manufacturing a luminaire according to claim 7 , wherein the step of introducing the core into the recess includes melting part of the housing.

9. The method of manufacturing a luminaire according to claim 5 , wherein the step of creating a temperature differential includes cooling the core.

10. The method of manufacturing a luminaire according to claim 5 , wherein the step of forming a housing includes utilizing an additive manufacturing process.

11. A luminaire comprising:

a core made up of a first material;

an LED lighting arrangement mounted to the core;

a housing made up of a second material that is different from the first material, the housing including a recess and a finned part, the recess receiving the core, a central part in which the recess is provided, the finned part extending from the central part, the housing further including a fence part spaced from the central part so as to create a space therebetween, the fence part interconnecting adjacent fins to one another; and

a reflector secured to the housing, the reflector being configured to direct and focus light emitted by the LED arrangement.

12. The luminaire of claim 11 , wherein the reflector includes an integral attachment portion for securing the reflector to the housing.

13. The luminaire of claim 11 , wherein the core is made up of a material having a thermal conductivity greater than 34 W/m-K.

14. The luminaire of claim 13 , wherein the core is manufactured using at least one of additive manufacturing, casting, and extrusion.

15. The luminaire of claim 11 , wherein the housing is made up of a material having a thermal conductivity of at least 4 W/m-K.

16. The luminaire of claim 15 , wherein the housing is manufactured using at least one of additive manufacturing, molding, and extruding.
