Abstract: An improved waterproof structure for a miniature lamp bulb, whereof, the lamp bulb is assembled on a seat portion, two polar pins are exposed to the laterals outside of the seat portion to be insertion connected with a receptacle. The receptacle is provided with a round connecting pipe portion connecting the lamp bulb and the seat portion. A protecting cover is tightly assembled on the round connecting pipe portion for protecting the lamp bulb. At least a waterproof gasket is provided between the protecting cover and the round connecting pipe portion, hence the structure is a firmer and more reliable structure, and has a more ideal waterproofing function with high safety.

Abstract: A connecting unit for a lamp string, the connecting unit is a hollow connecting pipe made of transparent and flexible material, wherein each of the two ends of the connecting unit is provided therein with a connecting and positioning end to mate the diameter of a lamp holder of a lamp bulb, thereby, two mutually neighboring and confronting lamp bulbs of a lamp string are adapted to positioning in the connecting unit. With the connecting unit, a lamp string can be changed into some other type to thereby be more variable.

Abstract: A figure light assembly including a figured frame base, and a plurality of lights mounted on the figured frame base, wherein the figured frame base has a plurality of locating blocks raised from a top surface thereof, the locating blocks having a respective through hole; the lamp holders of the lights have a respective clip raised from the periphery and adapted for fastening to the through holes on the locating blocks for permitting the lights to be respectively retained to the locating blocks at a top side.

Abstract: A netted lamp device in a pattern of a matrix, including some lamp strings braided intercrossingly to form a lamp decoration, wherein, the lamp strings are braided intercrossingly with their conductors, the lamps on the matrix in some of the lamp strings are optionally arranged in pursuance of a designed pattern or letter, while the lamps in the outer ones of the lamp strings are arranged regularly along the boundary of the frame for the netted lamp device to form the peripheral edges of the netted lamp device; the lamp strings are controlled and driven by an external IC for some individual switches corresponding respectively to the lamp strings, so that a designed pattern or letter in pursuance of the matrix can be formed in the lamp decoration.

Abstract: A lamp socket set including on the top a lamp bulb socket and an engaging block on the bottom of the socket; the socket has therein two contacting pieces to connect respectively the periphery of a metallic contact annulus on the tailing end of and a central end tip of the lamp bulb, and two prongs on the contacting pieces; a receiving seat is provided on the bottom end of the socket and has a receiving space defined by its two sides with inside teeth, two recesses are provided on the top of the receiving space for receiving conductors; an engaging block conforming in shape with the receiving space is provided having external teeth corresponding in position to the inside teeth, and also is provided on its top surface opposing to the top of the receiving space with other recesses for press contacting the conductors; the engaging block is pressed vertically onto the receiving seat to render the prongs to extend through the conductors and can be removed horizontally.
