1. A lighting fixture comprising:
- a light-emitting arrangement having first and second ends defining an open space which has a centerline and including (a) at least one LED at the first end and (b) a heat sink connected to the at least one LED extending radially away from the centerline and having a length extending therefrom toward the second end;
LED power circuitry components spaced from the light-emitting arrangement and positioned adjacent the second end of the light-emitting arrangement; and
an elongate tubular channel formed on the centerline and having wiring therein from the power-circuitry components to the LED(s).

Abstract
A lighting fixture including a light-emitting arrangement having first and second ends. The light-emitting arrangement includes (a) at least one LED at the first end and (b) a heat sink connected to the at least one LED and having a length extending therefrom toward the second end. There are LED power circuitry components spaced from the light-emitting arrangement and positioned adjacent the second end of the light-emitting arrangement. The fixture includes an elongate tubular channel formed along the length of the heat sink and having wiring therein from the power-circuitry components to the LED(s).

21. A lighting fixture comprising:
-
a light-emitting arrangement having first and second ends defining an open space which has a centerline and including (a) at least one LED at the first end and (b) a heat sink connected to the at least one LED and having a length extending therefrom toward the second end, the light-emitting arrangement being held substantially on the centerline to facilitate fluid-flow along the heat sink; LED power circuitry components spaced from the light-emitting arrangement and positioned adjacent the second end of the light-emitting arrangement; and an elongate tubular channel formed along the length of the heat sink and having wiring therein from the power-circuitry components to the LED(s).

22. A lighting fixture comprising:
-
a housing defining an open space which has a centerline and an inner surface with closed-perimeter first and second edges; a light-emitting arrangement being disposed within the open space and secured with respect to the housing and having first and second ends, and including (a) at least one LED at the first end and (b) a heat sink connected to the at least one LED extending radially away from the centerline and having a length extending toward the second end; LED power circuitry components spaced from the light-emitting arrangement and positioned adjacent the second end of the light-emitting arrangement; and an elongate tubular channel formed on the centerline along the length of the heat sink and having wiring therein from the power-circuitry components to the LED(s).
