Abstract

An apparatus and related method for housing a light assembly apparatus includes a housing having a housing first end and a housing second end arranged along a central axis, the housing further includes a plurality of fins each having a fin first end and a fin second end, the plurality of fins forming a plurality of vents therebetween, each the plurality of fins has a curvature extending from the fin second end such that the plurality of fins converge towards the central axis proximate each fin first end, an endpiece proximate the housing first end and arranged proximate to the fin first end of each of the plurality of fins, the endpiece having a circular portion including a continuous circumference about the central axis, an electrical connector arranged proximate to the endpiece and arranged along the central axis, and a space arranged along the central axis proximate the housing second end and further configured with the plurality of fins and the plurality of vents arranged therearound, the space configured to, at least in part, house a light assembly. Other embodiments are disclosed as well.

Claims

1. An apparatus for a light assembly comprising:

a housing comprising a housing first end and a housing second end arranged along a central axis, the housing further comprising;

a plurality of fins each having a fin first end and a fin second end, the plurality of fins forming a plurality of vents therebetween, each the plurality of fins has a curvature extending from the fin second end such that the plurality of fins converge towards the central axis proximate each fin first end;

an endpiece proximate the housing first end and arranged proximate to the fin first end of each of the plurality of fins, the endpiece having a circular portion comprising a continuous circumference about the central axis;

an electrical connector arranged proximate to the endpiece and arranged along the central axis; and

a space arranged along the central axis proximate the housing second end and further configured with the plurality of fins and the plurality of vents arranged therearound, the space configured to, at least in part, house a light assembly.

2. The apparatus of claim 1, wherein the plurality of fins are configured to form a parabolic shape, at least in part.

3. The apparatus of claim 2, wherein the vents are arranged proximate an electronic heat generating source within the space and the vents are configured to provide venting of the generated heat.

4. The apparatus of claim 2, wherein the plurality of fins converge and merge with a common portion of the housing about midway along an overall length of the housing.

5. The apparatus of claim 1, wherein the housing forms a shape similar to at least one of a PAR 30 or a PAR 38 light.

6. The apparatus of claim 1, wherein the light assembly is configured to emit light out of the housing second end.

7. The apparatus of claim 6, wherein the light assembly includes one or more light emitting diodes (LED).

8. The apparatus of claim 1, wherein at least a portion of the housing is formed of a synthetic material.

9. The apparatus of claim 1, wherein at least a portion of the plurality of fins is formed of a synthetic material.

10. A light assembly apparatus comprising:

a housing comprising a housing first end and a housing second end arranged along a central axis, the housing further comprising;
