Abstract
An LED lighting fixture including a housing having a hollow interior cavity defined by a backwall and a surrounding wall extending therefrom to a forward edge. An LED illuminator is mounted in the housing. An LED-support structure extends in the interior cavity from the housing to an LED-supporting surface positioning the LED illuminator in a desired orientation and spaced from the backwall. The LED-support structure is a heat sink transferring heat from the LED illuminator to the housing.

An LED lighting fixture comprising:
- a housing with a hollow interior cavity defined by a single-piece wall structure comprising a backwall, a support structure extending from the backwall to an LED-supporting surface spaced from the backwall, and a surrounding wall extending to a substantially planar forward end;
- a plurality of spaced apart LED illuminators mounted at the LED-supporting surface within the interior cavity;
- and
- a single-piece reflector comprising a plurality of reflector cups each surrounding a corresponding one of the LED illuminators at the LED-supporting surface and extending therefrom to a common substantially planar flange portion at the forward end of the housing.
