LED bulb, lamp holder, or adaptor including a module that extends beyond a shade, cover, or other light blocking element to permit signal or light transmission to or from the module

1. An LED light device, comprising:

a light device body and means for electrically connecting the LED light device to a power source upon insertion of the LED light device into a light socket;

an extendable module arranged to extend from and to be retracted into said light device body, wherein said extendable module includes circuitry and an electronic unit for wireless electromagnetic communication comprising at least one of a sensor, a remote control, an integrated circuit, and a digital data recording and storage device;

at least one LED arranged in the light device body outside said extendable module;

a blocking means included in said light device body that interferes with transmission and reception of wireless electromagnetic signals to and from said electronic unit when said extendable module is retracted into the light device body, thus interfering with operation of the electronic unit;

wherein when said extendable module is extended from said light device body, said blocking means no longer interferes with transmission and reception of wireless electromagnetic signals to and from said electronic unit, thus allowing operation of the electronic unit without interference by the blocking means;

wherein said blocking means is one of a lamp cover, lamp shade, lamp glass, and light fixture; and

wherein the LED light device is an LED bulb.

2. An LED light device as claimed in claim 1 , wherein said means for electrically connecting include at least one of a screw plug, a pin plug, and a position-and-twist plug.

3. An LED light device as claimed in claim 1 , further comprising stopper means for stopping extension of said extendable module from the light device body.

4. An LED light device as claimed in claim 1 , further comprising a heat sink for conducting heat to an outside of the light device body.

5. An LED light device as claimed in claim 1 , wherein the LED light device further comprises optics means for modifying light from said at least one LED, said optics means including at least one of a concave, convex, or condensing lens, stencil, window, opening, cut-out, reflector, retro-reflector, and adjustable focus mechanism.

6. An LED light device as claimed in claim 1 , wherein the LED light device is included in at least one of a desk lamp, table lamp, reading lamp, mirror lamp, floor lamp, wall lamp, outdoor lamp, indoor lamp, ceiling lamp, chandelier lamp, track lighting, garden lamp, and seasonal lamp.

7. An LED light device as claimed in claim 1 , wherein the extendable module extends from one end, both ends, or at least one surface of the LED bulb, lamp holder, or lamp holder adaptor.

8. An LED light device as claimed in claim 1 , wherein said circuitry and additional electric parts and accessories are fitted within compartments in said extendable module.

9. An LED light device as claimed in claim 1 , wherein said light device body includes a circuit board on which said at least one LED is mounted.

10. An LED light device as claimed in claim 1 , wherein said means for electrically connecting include means for enabling twisting of the extendable module to a selected orientation when the LED light device is plugged into a socket, thereby enabling the electronic unit in the extendable module to be aimed in a desired direction.

11. An LED light device as claimed in claim 1 , further comprising lock means to lock the extendable module at least one predetermined extension position.
