Abstract: A combined display frame and lamp system is provided. This system includes a display frame; a mount fastened to the display frame; and, a lamp holder secured relative to the display frame through a connecting mechanism coupled to the mount. The system also includes a back support pivotally coupled to the mount for supporting the mount and the display frame on a support surface.

Abstract: A socket assembly for a lamp is provided that includes a triggering tab made from an insulating material. An isolating plate is disposed below the triggering tab. Each side of the isolating plate is provided with a shaft which has a threaded outer portion. Each shaft has a socket made from an electrically conductive material disposed thereon. Each socket is attached to a respective shaft by means of a hole formed through the socket. Each socket is provided with a slot for receiving and retaining a connecting pin of a light bulb. The threaded portion of each shaft extends through the hole for connection with a connecting rod made from an electrically conductive material. The connecting rod can be suitably supported by a supporting device. When a light shade is to be attached, a pair of shade fixing springs are applied that are attached to a respective annular groove of each connecting rod, the socket and the top of the shade.

Abstract: A type of lamp track clamp structure, comprising a main unit, first fixing pieces, second fixing pieces, clamp pieces and conductive screws, the first fixing pieces and the second fixing pieces are installed in the main unit, the two clamp pieces are fitted on the front and back sides of the main unit, the conductive screws are screwed through the clamp pieces and the main unit to compose a lamp track clamp structure; the above configuration is so designed that the track clamp may involve a universal purpose to significantly reduce production costs and enable convenient operation.

Abstract: A tripod including a tripod head supported on tripod legs and formed of two symmetrical half shells and defining a ball socket between the half shells, a camera platform adapted for holding a camera and having a ball at the bottom mounted in the ball socket of the tripod head, a hexagon nut mounted within a hexagonal hole in one half shell of the tripod head, a lock screw inserted through a respective mounting hole in each half shell of the tripod head and threaded into the hexagon nut and then screwed up with a cap nut, wherein turning the lock screw in one direction causes the two half shells of the tripod head to be released from each other for permitting the ball of the camera platform to be turned to the desired angle; turning the lock screw in the reversed direction causes the ball of the camera platform to be firmly retained in the ball socket of the tripod head in position.
