A light assembly includes a housing containing at least one solid state lighting device. The solid state lighting device electrically communicates with an AC energy source in a known manner. At least one photovoltaic cell is connected to an inner wall of the housing adjacent to the solid state lighting device whereby the photovoltaic cell absorbs radiative energy from the solid state lighting device. At least one battery pack derives energy from the artificial light of the lighting device, by and through the photovoltaic cell. One or more LED lights, or an LED array, are contained within the housing, and electronically communicate with the battery pack. An actuation sensor activates a switching means to energize the LED light(s) with DC power from the battery pack. |
