Abstract
An exemplary power regulator apparatus provides power for illumination of a display object, such as a merchandise package or container, which has a light emitting apparatus comprising a secondary inductor and an illumination source. A support structure, such as a point of purchase display, typically contains or supports one or more power regulators and display objects. The power regulator comprises a controller and a primary inductor, and the controller is adapted to provide a voltage or current to the primary inductor to generate a primary inductor voltage. The controller may also comprise a plurality of switches and a memory adapted to store values for switching frequency or switch on-time durations or pulse widths. The illumination source emits visible light when the power regulator is in an on state and when the secondary inductor is within a predetermined distance of the primary inductor.
