  • Patent number: 6902292
    Abstract: A refined illuminating lamp structure is disclosed. A lamp case is pivotally connected to a top surface of the holder so as to reverse on the top surface of a holder. The bottom surface of the holder is connected with a taper body. The top surface of the taper body has a wire-fixing opening mounted thereon and a power conducting element is set at the connecting plane of the holder and the taper body. The power conducting element has one end which is a conducting wire and the other end exposed to have an awl conducting piece. The conducting piece is placed in the wire-fixing opening and the conducting wire connects with the illuminator inside the lamp case along the side of the holder. Several illuminating lamps are simultaneously plugged in the outdoor lawn and a long conducting wire having a power socket is placed in the power fixing opening at the top surface of the taper body.

  • Patent number: 6786753
    Abstract: An improved socket structure comprises essentially a socket, an ellipse-shaped rotation foundation is disposed in the socket, a top is to combine with the top side of the socket and is firmly fixed on the rotation foundation for driving the rotation foundation to rotate; two sides in the socket are respectively configured with a ball, the ball is capable of entering the power jack of the socket; when the electric conduction copper flakes of a plug are inserted into the power jacks of the socket, the top drives the rotation foundation to rotate for generating an angle, then the ball is pushed into the power jacks by the rim of the rotation foundation and lodged in the power jacks into which the electric conduction flakes of the plug are inserted, thus the plug is inseparable from the socket; if the user wants to unplug the plug from the socket, he could just screw the top to make the balls out of the power jacks into which the electric conduction flakes are inserted, and makes it possible to separate the plug

  • Patent number: 6300570
    Abstract: A portable multi-outlet assembly with turnable eave. The assembly is equipped with an eave engaged to the face plate of the multi-outlet assembly with two set buttons set on respective eye holes provide at both sides of the ave so as to make the eave turnable in two semi-circular slots formed at both sides of the eave. Moreover, the movement of the eave is so arranged that it is turnable upward up to 180° until the button claw mate with the stoppers in two slots of the eave. At this time the operator is able to insert plugs into the outlets at a most ergonomically comfortable direction of 45° inclination. The multi-outlet assembly can be set on the ground by a bayonet-shaped post with the face plate of the assembly parallel to the ground such that the inserted plugs can also be shaded by the eave thereby preventing entry of rain water into the multi-outlet assembly.

  • Patent number: 6250773
    Abstract: A novel night lamp comprises essentially by positioning a luminescent sheet against snap protrusions provided in a semi-circular arc-like upper shade such that the luminescent sheet can be affected by said arc curvature of said upper shade to form a corresponding semi-circular arc plane and protrude out of an open portion on said upper shade. As said upper shade covers said night lamp body, the luminescent sheet is hold between the upper shade and the semi-circular arc-like protruding block of the night lamp body and fits intimately against the protruding body. At the same time, the conductive ends extended on ends of said luminescent sheet will contact conductive springs slipped on shaft levers provided on a positioning seat of said night lamp body. As a result, an electric power can be conducted via said conductive copper pieces and said conductive springs to said luminescent sheet and activate said luminescent sheet to luminescence.

  • Patent number: 6190017
    Abstract: An improved structure of electric luminescence night lamp comprises a main housing body, a electric luminescence piece and a top cover. The main housing body is provided with a receptacle at its front face for reception of the electric luminescence piece, and a plug on its back for connecting with power supply to lighten the electric luminescence piece. A rectangular opening formed at somewhere decent in the housing body is provided with lateral grooves and is sealed by a top cover with lateral tracks. The top cover is combined to the housing body by slipped the tracks into the grooves and is movable to open or close the rectangular opening, and moreover, the top cover is also provided with a plurality of anti-slip strips on its front face to prevent a finger from slipping when push it to move. In virtue of the top cover, a neighboring socket can be protected, or happening of unexpected dangers.

  • Patent number: 5964516
    Abstract: A night light includes a bottom member on which a receptacle is formed to receive and hold therein an electro-luminescent light source. The bottom member has two blade openings through which a pair of conductor blades extend to be adapted to fit into a first set of outlet openings of a wall outlet. The conductor blades are in contact engagement with two contact terminals of the light source to conduct electricity to the light source for generating light. A cover member is mounted to cover the bottom member to hold the light source and the conductor blades therein. The bottom member has an extended section adapted to overlap the wall outlet and having a passage corresponding to and exposing a second set of outlet openings of the wall outlet covered by the extended section of the bottom member.
