摘要：
A luminaire (10) includes a core (16) made up of a first material and an LED lighting arrangement (24) mounted to the core (16). The luminaire further includes a housing (14) made up of a second material. The second material is different from the first material. The housing (14) including a recess (40) in which the core (16) is received. The housing (14) further includes a finned part (38).
技术问题语段：
The technical problem addressed in this patent is to provide a composite luminaire that is more energy-efficient and visually appealing than traditional luminaires. The invention aims to achieve this by using a heat sink made of a first material and an LED lighting arrangement mounted on a core made of a second material that is different from the first material. The housing of the luminaire includes a recess in which the core is received, and a finned part that extends radially from the central part. A reflector is secured to the housing to direct and focus light emitted by the LED arrangement. The invention also includes a method of manufacturing the luminaire.
技术功效语段：
The patent describes a new type of luminaire that includes a core made of a first material and an LED lighting arrangement mounted on top of it. The luminaire also has a housing made of a different material from the core. The housing includes a recess where the core is placed and a finned part that helps to direct and focus the light emitted by the LEDs. This design helps to improve the performance and efficiency of the luminaire.
权利要求：
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 recess in which the core is received, the housing further including a finned part.
2. The luminaire of claim 1, wherein the housing includes a central part in which the recess is provided, and wherein the finned part includes a plurality of fins that extend radially from the central part.
3. The luminaire of claim 2, wherein the plurality of fins are arranged so that a periphery of the finned part forms a substantially circular shape.
4. The luminaire of claim 2, wherein the plurality of fins are arranged so that a periphery of the finned part forms a substantially square shape.
5. The luminaire of claim 2, wherein the housing includes a fence part, the fence part interconnecting adjacent fins to one another.
6. The luminaire of claim 1 further comprising a reflector, the reflector being configured to direct and focus light emitted by the LED lighting arrangement.
7. The luminaire of claim 6, wherein the reflector includes an integral attachment portion for securing the reflector to the housing.
8. The luminaire of claim 7, wherein the attachment portion is provided as a pair of arms that engage with recesses provided on the housing.
9. The luminaire of claim 1, wherein the core is made up of a material having a thermal conductivity greater than 34 W/m-K.
10. The luminaire of claim 1, wherein the housing is made up of a material having a thermal conductivity of at least 4 W/m-K.
11. A method of manufacturing a luminaire comprising the steps of: forming a core from a first material; forming a housing from a second material different from the first material, the housing including a recess; 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.
12. The method of manufacturing a luminaire according to claim 11, wherein the step of forming a core includes forming a core with a first width, and wherein the step of forming a housing includes forming a recess with a second width, the second width being less than the first width.
13. The method of manufacturing a luminaire according to claim 11, wherein the step of creating a temperature differential includes heating the core.
14. The method of manufacturing a luminaire according to claim 11, wherein the step of creating a temperature differential includes cooling the core.
15. The method of manufacturing a luminaire according to claim 11, wherein the step of forming a housing includes utilizing an additive manufacturing process.
