Configurable power supply circuit for lighted shelves in a refrigerator
First Claim
1. A refrigerator appliance comprising:
- a cabinet having a temperature-controlled compartment defined therein;
a plurality of shelf mounting positions disposed in the temperature-controlled compartment;
a first adjustable shelf carrying at least one lighting device;
a second adjustable shelf carrying at least one lighting device, each of the first and second shelves being removably mounted in one of the plurality of shelf mounting positions; and
a power supply circuit configured to;
a) determine which of the plurality of shelf mounting positions the first shelf is mounted in;
b) determine which of the plurality of shelf mounting positions the second shelf is mounted in; and
c) supply power to the first shelf based on the determined position of the first shelf and the determined position of the second shelf.

Abstract
Illustrative embodiments of systems and methods for powering lighted shelves in refrigerator appliances are disclosed. In one embodiment, a refrigerator appliance may comprise a cabinet having a temperature-controlled compartment defined therein and a plurality of electrical connectors disposed at a plurality of shelf mounting positions within the temperature-controlled compartment. The refrigerator appliance may also comprise a plurality of adjustable shelves each carrying at least one light emitting diode (LED), where each of the plurality of adjustable shelves may be removably mounted in one of the plurality of shelf mounting positions such that the at least one LED is electrically coupled to one of the plurality of electrical connectors. The refrigerator appliance may further comprise a power supply circuit that is electrically coupled to the plurality of electrical connectors and that is configured to selectively supply power to only a subset of the plurality of electrical connectors.
