Abstract: A wall mounting decorative shelf assembly includes a mounting face, a support frame mounted on the mounting face, a mounting bracket mounted in the support frame, and a decorative shelf adjustably mounted on the support frame and combined with the mounting bracket by a plurality of threaded fastening members. The support frame has two upright sides each provided with a plurality of adjusting slots to allow passage of the fastening members. Thus, the fastening members are movable in the adjusting slots of the support frame so that the decorative shelf is movable relative to the support frame to adjust the position between the decorative shelf and the support frame so that the position of the decorative shelf can be adjusted slightly, and the decorative shelf can be mounted on the support frame easily and conveniently.

Abstract: A connecting device for a pendent lamp includes a first connector and a second connector rotatably mounted on the first connector. Thus, the first connector is rotatable relative to the second connector to adjust the angle and direction of the pendent lamp so that the pendent lamp is adjustable to have the optimum angle and direction. In addition, the rotation ring of the second connector is limited between the first threaded connecting member and the second threaded connecting member of the first connector after the first threaded connecting member and the second threaded connecting member of the first connector are combined together so that the connecting device is assembled easily and quickly.

Abstract: A lamp includes a lamp body, a threaded mounting seat, a threaded catch sleeve, a locating slide, a connecting member, and a lamp pole unit. The catch sleeve is rotatable relative to the mounting seat to push the locating slide toward the mounting seat and to move the male connector toward the female connector so that the male connector is connected to the female connector to form an electrical connection of the lamp. Thus, the male connector is not rotatable relative to the female connector when the male connector is movable relative to the female connector to prevent the first electric cords of the female connector and the second electric cords of the male connector from being distorted or tangled with each other.

Abstract: A sounding lamp includes a control module, a transmission seat, a connecting interface, a sounding unit, and an illuminating unit. The control module includes a micro control unit, at least one transmission connector, a sound effect control circuit and a light regulation control circuit. Thus, the sounding lamp integrates the sounding and lighting functions. In addition, the sounding lamp is directly connected to a digital equipment by a transmission seat or externally connected to a digital equipment by a connecting interface, thereby enhancing the versatility of the sounding lamp.

Abstract: A lamp socket adapter includes an adapter body, a threaded sleeve, a slot type socket, two locking bars, and two elastic members. Thus, the lamp socket adapter converts a screw type socket into a slot type socket irreversibly. In addition, the arc-shaped guide face of each of the locking bars is directed toward a rotation direction of the outer thread of the threaded sleeve to guide rotation of the outer thread of the threaded sleeve.
