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.
Claims10
A screw-in type base for a light-emitting diode (LED) lighting device comprising:
- an LED light source;
- and
- a movable conductor mounted in the center of the base, and configured to make electrically conductive contact with a center conductor of a socket the base is screwed into,
- wherein the movable conductor is configured to remain in electrical communication with the LED light source.
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.
