ABSTRACT:
An incandescent lamp socket comprises a housing for receiving the base portion of an incandescent lamp and switch means for selectively connecting the lamp's contacts to a source of electrical energy. Such switch means comprises a rotatably mounted cylindrical sleeve which surrounds the socket housing, and means responsive to rotational movement of the sleeve relative to the housing for selectively connecting the lamp contacts to the energy source. Preferably, such connecting means comprises a planetary ring gear disposed along the interior wall of the sleeve, a cooperating pinion gear mounted for rotational movement on the socket housing, cam means rigidly coupled to the pinion gear and rotatable therewith, and electrically energized cam follower means, movable in response to the cam means to selectively energize certain socket electrodes which are connected to the contacts of a lamp supported by the socket housing. According to another embodiment, the pinion gear is used to control the output of a conventional potentiometer which, in turn, controls lamp power.
