Abstract

Disclosed is a touch control lamp system, including a touch control dimmer switch adapted to be plugged into a standard electrical household outlet, and a lamp having a male electrical plug adapted to plug into the touch control switch. When the plug from the lamp is plugged into the touch control switch, a touch control wire in the power cord of the lamp connects a conductive portion of the lamp to the touch control circuitry in the touch control switch, so that the lamp may be controlled by touching the conductive portion of the lamp. Moreover, a conventional lamp may be plugged into the touch control switch, which may be controlled by a touch control wire separately connected to the touch control switch.

Claims

1. A touch control lamp system, comprising:

a housing;

a touch control circuit mounted within said housing, said touch control circuit having a touch control terminal, an input for providing power to said touch control circuit, and an output for providing output power controlled by said circuit in response to touching contact communicated to said touch terminal;

a female electrical outlet on said housing, connected to the output of said touch control circuit and configured to receive a standard male electrical household plug;

a lamp having a power cord terminating in a male electrical plug configured to be plugged into a standard female electrical household outlet for supplying power to the lamp;

a touch control wire on said cord having a first end attached to an exposed conductive portion of said lamp, and a second end terminating at said male plug; and

means on said plug and on said housing for connecting said second end of said touch control wire on said male plug to said touch control terminal on said housing when said plug is inserted into said outlet, so that said touch control circuit may be actuated by touching said conductive portion of said lamp, wherein said touching is communicated by said touch control wire to said control circuit.

2. The system of claim 1, further comprising means on said housing for attaching a second touch control wire to said touch control terminal.

3. The system of claim 1, wherein said means for connecting said touch control wire to said touch control terminal comprise:

a first contact carried by said housing in the proximity of said outlet and connected to said touch control terminal; and

a second contact carried by said plug connected to the second end of said touch control wire adapted to make electrical contact with said first contact when said plug is inserted into said outlet.

4. The system of claim 3, wherein said first contact extends outwardly from said housing.

5. The system of claim 4, wherein said plug has a body portion having a flat side, and a pair of prongs extending out orthogonally from said flat side on one side of the plane defined by said flat side, said prongs configured to be plugged into a standard female electrical household outlet, and wherein said second contact is on the other side of said plane.

6. The system of claim 1, wherein said power cord comprises three side-by-side conductors, and wherein the conductor on one side is the touch control wire, and the conductor in the middle and the conductor on the other side are power conductors for supplying power to the lamp.

7. A lamp control device, comprising:

a housing;

a touch control circuit mounted within said housing, said touch control circuit having a touch control terminal, an input for providing power to said touch control circuit, and an output for providing output power controlled by touching contact communicated to said touch terminal;

a female electrical outlet on said housing, connected to the output of said touch control circuit and configured to receive a standard male electrical household plug, said outlet also configured to receive a modified male electrical household plug to which is connected a non-power carrying touch control wire; and

a contact adjacent to said outlet and connected to said touch control terminal, said contact adapted to make electrical connection with said touch control wire when said modified plug is inserted into said outlet, while not interfering with the insertion of a standard male electrical household plug into said outlet.

8. The device of claim 7, further comprising a means on said housing for connecting a second touch control wire to said touch control terminal.

9. The device of claim 7, in which said contact extends generally outwardly from said housing.

10. A lamp for use with a touch control circuit, comprising:

a lamp base carrying an incandescent bulb;

a cord having one end connected to said base;

a pair of power conductors in said cord for supplying power to said incandescent bulb;

an exposed conductive portion on said lamp;

a touch control wire in said cord having one end thereof electrically connected to said conductive portion;

a male electrical household plug on the other end of said cord, said plug having a body portion with a flat side, a pair of prongs extending out orthogonally from said flat side, said prongs being connected to said power conductors, said plug adapted to be plugged into a standard female electrical household outlet for supplying power to the lamp; and

a contact carried by said plug electrically connected to said touch control wire, said plug further being adapted to be inserted into a specially-designed electrical outlet connected to the output of a touch-control circuit, so that when said plug is inserted into said specially designed outlet, said touch control wire is connected through said electrical contact to a touch control terminal in said circuit, whereby said circuit can be actuated to supply power to said lamp by touching said conductive portion on said lamp.

11. The lamp of claim 10, wherein said contact is located on the plug body portion on one side of a plane defined by said flat side, and said prongs extend out of said plug on the other side of said plane.

12. The lamp of claim 10, wherein said cord comprises three side-by-side conductors, and wherein the conductor on one side of said cord is said touch control wire, and wherein the conductor in the middle and the conductor on the other side are said power conductors.

13. The lamp of claim 11, wherein said plug has a second side on said body portion generally perpendicular to said flat side, and said contact is an exposed button on said second side.
