Abstract
A light fixture (200) comprises a mounting fixture (501) that is configured and arranged to facilitate mounting the light fixture to a mounting surface other than ground along with at least a first light socket (502) and a plurality of permanently mounted light emitting diodes (LED's) (503). The light socket and the LED's are supported by the mounting fixture. The LED's are configured in an array and are oriented towards the mounting surface when the light fixture is installed on the mounting surface. This light fixture can further comprise an ambient light sensor (504), an animate object detector (505), and/or a timer (506). The wall-washing LED's can be switched on and off automatically (103) to provide the desired decorative effect during the evening hours. In addition, the light socket can be rendered controllable (105) as a function of whether it is dark out and whether an animate object has been detected.
