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.
