Abstract
A reliable, rotating, illuminated advertising display unit that utilizes independent display modules housing lights and advertising material. These are easily removed from the base unit for shipping, assembly, and replacement. Optionally, AMLCD, plasma, or similar flat-panel displays may be used in the display modules. The display modules surround a hollow central compartment that may be used for storing, collecting, or displaying products such as food or beverages, or as a trash container. Power is transmitted from the base via a slip ring to the lighting contained in the display modules so as to display advertising or similar matter. The rotational capability is provided via a motor, a gearing arrangement, a central tapered roller bearing, and rollers. The unit's power is provided by AC power when available, or by utilizing a fuel cell, e.g., a proton exchange membrane (PEM), methanol solid oxide, photovoltaic cells, battery, or some combination thereof.
