Power supplies for lighted shelves in a refrigerator
First Claim
1. A refrigerator appliance comprising:
- a cabinet having a temperature-controlled compartment defined therein;
a shelf ladder disposed at least partially in the temperature-controlled compartment and providing a plurality of shelf mounting positions, the shelf ladder comprising an electrical bus including first, second, and third bus conductors, the second bus conductor connected to a first circuit that supplies power at a first current level when electrically coupled to the first bus conductor, the third bus conductor connected to a second circuit that supplies power at a second current level when electrically coupled to the first bus conductor; and
a first adjustable shelf carrying a first lighting device, the first adjustable shelf being removably mountable in one of the plurality of shelf mounting positions such that the first lighting device is electrically coupled between the first bus conductor and the second bus conductor.
