Abstract: A rotation-controlled device for controlling actuation and de-actuation of the lamp comprises an upper cover; an arc strip protruded from an inner surface of the upper cover; a seat installed below the upper cover by using a connector; a button installed to the seat and resisting against the arc strip; the button being pushed to rotate by the arc strip; and a light adjuster installed below the button and aside the locking piece; the actuation of the light adjuster being controllable by the button. A bearing is installed below the upper cover and between the connector and the upper cover. A bottom cover is installed below the seat. The arc strip has teeth and the button has teeth. The one side of the arc strip has a sticky surface and a periphery of the button has another sticky surface.

Abstract: A rotation-controlled device for controlling actuation and de-actuation of the lamp comprises an upper cover; a cambered strip protruded from an inner surface of the upper cover; a seat installed below the upper cover by using a connector; a button installed to the seat and resisting against the cambered strip; the button being pushed to rotate by the cambered strip; and a light adjuster installed below the button and aside the locking piece; the actuation of the light adjuster being controllable by the button. A bearing is installed below the upper cover and between the connector and the upper cover. A bottom cover is installed below the seat. The cambered strip has teeth and the button has teeth. The one side of the cambered strip has a sticky surface and a periphery of the button has another sticky surface.

Abstract: An orientation change device serves for a lamp frame and light projection direction. An upper cap serves for guiding power. A lower end thereof is installed with an electric stud. Two ends of a connecting seat have insulated plugs. A conductive post is positioned in each of the plug at a position corresponding the electric stud. A plurality of lamp seat are fixed to a periphery of the connecting seat by a frame. An inner surface of the conductive post is conductive to a wire of one of a plurality of lamp seat. A plurality of wires are electrically connected to the conductive post. Then the plugs containing the conductive posts are installed at two ends of the connecting seat. Thereby, any one end of the connecting seat is connected to the upper cap. Thus, the conductive posts are connective to the electric stud.

Abstract: A pendant elevation and projecting angle adjusting structure includes a locating disk fixedly fastened to the bottom end of a suspension rod at the ceiling, a plurality of pull ropes respectively inserted through equiangularly spaced wire holes at the locating disks, a lampshade and a balance plate respectively suspended from the ends of the pull rods below the locating disk, and a power cord inserted through the suspension rod and connected to the lampshade, wherein the lampshade is tilted to change the light projecting angle of the lamp bulb when one pull rope is pulled; the elevation of the lampshade is changed when the balance plate is pulled downwards or lifted.

Abstract: A desk lamp which includes a lamp stand, a supporting base revolvably supported on the lamp stand, two support arms symmetrically fastened to the supporting base at two opposite sides, two coupling members respectively connected to top ends of the support arms remote from the supporting base, two lamp shade holder frames respectively pivoted to the coupling members, a lamp holder holding a lamp bulb, two connecting rods bilaterally coupled between the lamp holder and the lamp shade holder frames, a reflector mounted on the connecting rods around the lamp holder, and a lamp shade supported on the lamp shade holder frames around the lamp holder, the lamp bulb and the reflector, the lamp shade having an inside wall coated with a layer of light reflecting substance.
