Abstract

An adapter unit, having a body portion for containing circuitry to control a light bulb, and a threaded socket to receive the light bulb, is formed and configured to have a threaded extension to be received by a lamp socket, recessed into the body, lowering the vertical profile of the light bulb/adapter unit combination.

Claims

1. An adapter for a system of the type to remotely control an electrical light bulb of the type having a threaded stem for electrical connection to a matingly configured receptive lamp socket having an annular sidewall defining an internally threaded receptacle for receiving the threaded stem of the light bulb, the adapter operating to mount the light bulb to the lamp socket, the adapter including electronic means responsive to a remotely located control device for controlling communication of electrical power from the light socket to the light bulb, the adapter comprising:

a body portion carrying and containing the electronic means, there being a cavity defining internal sidewalls formed in the body portion;

a socket formed in the adapter for threadably receiving the threaded stem of the light bulb; and

a threaded extension formed and configured to be matably received by the lamp socket, the threaded extension extending into the cavity of the body portion in a manner that has the internal sidewalls of the cavity in surrounding relation to at least a portion of the threaded extension, the threaded extension and the cavity being dimensioned so that a space is formed therebetween in which is received at least a portion of the annular sidewall of the lamp socket.

2. The adapter of claim 1, wherein the body portion is formed from an electrically insulative material.

3. The adapter of claim 1, wherein the socket and the cavity formed in the body portion are generally co-linear to one another.

4. The adapter of claim 1, wherein the cavity of the body portion surrounds more than one half of the predetermined length of the threaded extension.

5. The adapter of claim 1, wherein the cavity of the body portion encircles at least one-third of the predetermined length of the threaded extension.

6. An adapter for use in lamp apparatus of the type including a light socket having an annular sidewall defining an internally threaded receptacle for receiving a threaded stem of a light bulb, the adapter operating to mount a light bulb having a threaded stem to the light socket for controllably communicating electrical power thereto, the adapter including electronic means to effect control of communication of electrical power from the light socket to the light bulb, the adapter comprising:

a body element carrying and containing the electronic means, there being a generally annular cavity located in the body portion;

a threaded adapter socket formed in the body element for receiving the threaded stem of the light bulb;

a threaded extension matably received by the light socket of the lamp apparatus, the threaded extension extending into the cavity of the body element in generally co-linear relation with the threaded adapter socket and so that a portion of the threaded extension is surrounded by the cavity, and the remaining portion of the threaded extension extends out of the cavity, the threaded extension and the cavity being dimensioned to provide a space that receives at least a portion of the annular sidewall of the light socket.

7. The adapter of claim 6, wherein the body portion is formed from an electrically insulative material.

8. The adapter of claim 6, wherein the socket and the cavity formed in the body portion are generally colinear and concentric to one another.

9. The adapter of claim 7, wherein the cavity of the body portion surrounds more than one half of the predetermined length of the threaded extension.

10. The adapter of claim 7, wherein the cavity of the body portion encircles at least one-third of the predetermined length of the threaded extension.

11. An adapter for use in lamp apparatus of the type including an electrical light bulb having a threaded stem in electrical connection with a matingly configured threaded recess of a light socket having an outer annular surface concentric with and defining the threaded recess of the lamp socket, the adapter operable to mount the light bulb to the light socket for controllably communicating electrical power thereto, the controller adapter including electronic means responsive to a controller means to effect control of communication of the electrical power from the light socket to the light bulb, the adapter comprising:

a body element, of an insulative material, and having a generally annular cavity formed therein;

a threaded adapter socket in the body receiving the threaded stem of the light bulb;

a threaded extension matably received by the light socket of the lamp apparatus, the threaded extension extending into and away from the cavity of the body element in generally co-linear relation with the threaded adapter socket and so that a portion of the threaded extension si surrounded by the cavity, and the remaining portion of the threaded extension being no greater than approximately one-third the longitudinal length of the threaded extension positioned to extend out of the cavity, the threaded extension and the cavity being dimension to define a space that receives at least a portion of the annular surface of the light socket;

wherein the body element carries and contains the electronic means for controlling current flow between the threaded extension and the threaded adapter socket.
