Multiple level lamp adapter
First Claim
1. A lamp dimmer-adapter comprising A. a generally cylindrical housing having 1. first and second cavities at opposite ends and 2. a partition between said cavities, B. a lamp socket shell disposed in said first cavity to receive a lamp bulb therein, C. a lamp base across said second cavity bearing against a transverse surface of said housing and aligned with said socket shell, said base including a lamp base shell, D. at least one tab fastened to said base shell and extending through said partition, thereby preventing relative rotational movement between said housing and said lamp base, E. fastening means for fastening said socket shell and said tabs to said partition with said socket shell in contact with said tabs to provide electrical connection between said base and socket shells and to secure said socket shell and said base to said housing, F. a socket center contact fastened to said partition in said first cavity and extending through said partition into said second cavity, G. a base center contact extending from the exterior of said base into the interior thereof, H. an electronic assembly including solid state switching means and 1. disposed in said base, 2. connected to control conduction between said center contacts by means of said solid state switching means, and 3. arranged for closer thermal coupling with said base than with a lamp in said shell, I. a control section disposed on a side of said housing, said control section comprising 1. lateral extension of said housing having a third cavity therein, 2. a variable circuit element disposed in said third cavity, 3. a control knob for varying said circuit element, and J. means connecting said variable circuit element to said electronic assembly for control of the conduction of said solid state switching means by means of said variable circuit element.
