Abstract
An illuminated drain assembly for a sink basin having a drain opening. The illuminated drain assembly includes a tube having a top end fluidly coupled to the drain opening of the sink basin. A drain stopper seals the drain opening of the sink basin. A light-emitting device is mounted to the drain stopper. A first electrical conductor is coiled around an outer surface of the tube. The first electrical conductor has two opposite ends electrically connected to a voltage source. A second electrical conductor is coiled around an inner surface of the tube at a location such that an electrical current through the first electrical conductor induces an electrical current through the second electrical conductor. The second electrical conductor has two opposite ends electrically connected to the light-emitting device.
Claims26
An illuminated drain assembly for a sink basin having a drain opening, the illuminated drain assembly comprising:
- a tube having a top end configured to be fluidly coupled to the drain hole of the sink basin;
- a drain stopper configured to seal the drain opening of the sink basin;
- a light-emitting device mounted to the drain stopper;
- a first electrical conductor coiled around an outer surface of the tube, the first electrical conductor having two opposite ends configured to be electrically connected to a voltage source;
- and
- a second electrical conductor coiled around an inner surface of the tube at a location such that an electrical current through the first electrical conductor induces an electrical current through the second electrical conductor, the second electrical conductor having two opposite ends configured to be electrically connected to the light-emitting device.
A illuminated drain assembly for a sink basin having a drain opening, the illuminated drain assembly comprising:
- a tube having a top end configured to be fluidly coupled to the drain opening of the sink basin, the tube having a through-hole along its length;
- a drain stopper configured to seal the drain opening of the sink basin;
- a light-emitting device mounted on the drain stopper;
- an electrical conductor extending through the through-hole of the tube;
- and
- a grommet supported within the through-hole and receiving the electrical conductor, the electrical conductor having a first end electrically connected to the light-emitting device, and a second end configured to be electrically connected to a voltage source.
A illuminated drain assembly for a sink basin having a drain opening, the illuminated drain assembly comprising:
- a tube having a top end configured to be fluidly coupled to the drain opening of the sink basin;
- a light-emitting device associated with the drain opening;
- an electrical conductor configured to apply a voltage to the light-emitting diode when the electrical conductor carries an electrical current;
- a switch connected in series with the electrical conductor;
- and
- a presence detector configured to:
- sense a presence of a human being in a vicinity of the sink basin;
- cause the switch to be closed such that the electrical conductor is able to carry electrical current when the presence of the human being in the vicinity of the sink basin is sensed;
- and
- cause the switch to be open such that the electrical conductor is unable to carry electrical current when the presence of the human being in the vicinity of the sink basin is not sensed.
