Abstract
A modified screw-in (Edison) type base for LED lighting devices that enables directional LED devices to be used in existing sockets. A movable center contact in a standard Edison type threaded base that enables the base to be screwed into a socket to make electrical contact while allowing the base to be rotated at least a half turn to allow a directional LED device to be aimed were the light is desired. The modified screw-type base that has a movable mount enabling a directional LED device to be firmly screwed into a standard bulb socket, then rotated to aim the light where it is desired.

7. A screw-in type base for an LED lighting device comprising:
-
an outer cylinder and an inner cylinder, wherein the inner cylinder is at least partially inside the outer cylinder, and wherein the inner cylinder is configured to rotate up to one-quarter turn clockwise or counterclockwise relative to the outer cylinder and wherein further rotation of the inner cylinder causes the outer cylinder to turn; and a light-generating portion of the device connected to the inner cylinder and configured to rotate with the inner cylinder, wherein the light-generating portion comprises an LED light source; and a metal contact in electrical communication with the LED light source, and configured to make electrically conductive contact with a center conductor of a socket the base is screwed into. - View Dependent Claims (8, 9, 10)
