Apparatuses for providing power for illumination of a display object

摘要

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.

主权项

1. An apparatus for providing power to an emitting apparatus having a first secondary inductor and an illumination source, the apparatus comprising:
a primary inductor; a controller coupled to the primary inductor, the controller to control a voltage or current provided to the primary inductor to generate a first primary inductor voltage or current for the illumination source to emit visible light when the first secondary inductor is within a predetermined distance of the primary inductor; and a feedback circuit coupled to the controller, the feedback circuit comprising a second, feedback secondary inductor.
