ABSTRACT:
A lighted serving tray includes a tray body having platter portion and a chamber portion attached to the underside of the platter portion. The chamber portion houses a plurality of lights which are installed in a perimetric wall thereof, a battery pack coupled to a recharging jack installed within the perimetric wall, and coupled to each of the lights via circuit elements, which includes at least one normally-on, on-off switch installed in a lower panel of the chamber portion, and which may include a flashing circuit. For a preferred embodiment of the invention, each of the lights is a light-emitting diode (LED) so as to minimize current drain. Also for the preferred embodiment of the invention, each of the on-off switches is installed within its own recess in the lower panel in such a manner that a movable activating element of the switch extends below a lower major surface of the lower panel. Thus, when the serving tray is placed on a substantially planar surface, the activating element is moved to an "off" position, thereby cutting power to the lights and to the flashing circuit.
