Abstract
A rotatable shelf illumination system may include a rotatable shelf having a groove in which one or more light sources may be mounted. A refractive lens may be mounted in the groove covering the one or more light sources. The rotatable shelf may be, for example, a lazy susan. A removeable and rechargeable power supply may be controlled by a controller circuitry to selectively energize the one or more light sources when rotation of the rotatable shelf is detected. A magnetic field sensor may be used with the controller circuitry to detect rotational movement of the rotatable shelf. The controller circuitry may implement energy conservation measures to prolong the charge of the rechargeable power supply.
Claims21
A rotatable shelf illumination system comprising:
- an electronics enclosure mountable on a rotatable shelf in a cabinet;
- a series of sequentially mounted light sources, the light sources mountable in a groove formed around a circumferential edge of the rotatable shelf and electrically coupled with a rechargeable power supply included in the electronics enclosure;
- and
- a refractive lens mountable in the groove formed around the circumferential edge of the rotatable shelf as a cover over the light sources.
A rotatable shelf illumination system comprising:
- a rechargeable power supply removeable installed in an electronics enclosure, the electronics enclosure mountable on a rotatable shelf;
- a light source mountable on the rotatable shelf and electrically coupled with the rechargeable power supply;
- a refractive lens mountable on the rotatable shelf to cover the light source;
- a controller circuitry included in the electronics enclosure, the controller circuitry configured to selective energize the light source in response to a change in rotational orientation of the rotatable shelf;
- and
- a magnetic field sensor in communication with or included in the controller circuitry, the magnetic field sensor configured to measure a magnetic field at any one of a plurality of different rotational positions of the rotatable shelf and the controller circuitry configured to determine the different rotational positions of the rotatable shelf based on the magnetic field, and determine the change in rotational orientation of the rotatable shelf is greater than a predetermined amount based on a difference between two of the determined different rotational positions.
A rotatable shelf illumination system comprising:
- a rotatable shelf for a cabinet, the rotatable shelf having a central aperture for coaxial coupling with a central post included in the cabinet, the rotatable shelf radially extending away from the central aperture to an outer edge of the rotatable shelf, the outer edge comprising a groove circumferentially extending around at least part of the outer edge;
- a light source disposed in the groove, wherein the groove is sized to receive the light source such that the light source is recessed into the outer edge of the rotatable shelf;
- an electronics enclosure mounted on the rotatable shelf, the electronics enclosure comprising a rechargeable power supply electrically coupled with the light source in the groove;
- and
- a refractive lens mounted in the groove to cover the light source.
