Abstract
A three-wire Christmas flashing control lamp includes a filament, a bimetal plate, and three conductive poles installed in the lamp. Three conductive wires are extended from the bottom end of the lamp. The lamp is mounted on a lamp base and then received by a lamp holder. The three-wire Christmas flashing control lamp is used to control the switching operation of a Christmas light string to further control the flickering effect of the light string.
Claims6
A three-wire flashing control lamp comprising:
- a central pole;
- a bimetal plate, having a first end attached to the central pole and a second free end;
- a first conductive pole;
- a second conductive pole installed adjacent to the central pole;
- a third conductive pole installed adjacent to the central pole and the second conductive pole;
- and
- a filament connected between the first conductive pole and the central pole;
- wherein the central pole, the first, second and third conductive poles, and the bimetal plate are each arranged substantially vertically within the lamp;
- and wherein the free end of the bimetal plate contacts with the second conductive pole when not heated by current from the first and second conductive poles, the free end bends away from said second conductive pole when heated by said current and contacts with the third conductive pole, and the free end returns after cooling to contact the second conductive pole, thereby creating a flickering effect.

A three-wire flashing control lamp comprising:
- a first conductive pole;
- a second conductive pole;
- a bimetal plate, having a first end attached to the second pole and a second free end;
- a third conductive pole installed adjacent to the second conductive pole;
- and
- a filament connected between the first conductive pole and the bimetal plate;
- wherein the free end of the bimetal plate is separated from the third conductive pole when not heated, while the free end of the bimetal plate bends and contacts with the third conductive pole when heated, thereby creating a flickering effect, wherein the first, second and third conductive poles, and the bimetal plate are each arranged substantially vertically within the lamp.
