ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a Christmas ornamental lamp, and particularly to a network knitted with a plurality of lamp strings.
2. Description of the Prior Art
In the conventional lamp strings for Christmas ornament, the ornament usually comprises an independent power-supply wire connected, in series, with a plurality of sockets, and the last socket on the tail end thereof is connected with an independent wire. Two independent power-supply wires are then twisted together to form into a lamp string; all the sockets in one lamp string are mounted with bulbs respectively so as to form into a lamp string for Christmas ornament.
The conventional lamp string for Christmas ornament can also be mounted on a wall surface or a wide plane; as shown in
FIG. 7
, a plurality of lamp strings are connected with and under a main power-supply cable. The two independent power-supply wires of every lamp string are not twisted; the sockets of two adjacent lamp strings are arranged in intersection shape. The independent power-supply wire of one lamp string and the sockets of another lamp string are held together by means of a clasper so as to knit all the lamps into a network of ornament; the aforesaid prior art is published in U.S. Pat. No. 5,775,802; the independent power-supply wires of the prior art are hung under the main power-supply cable; the number of strands of the power-supply wire and the diameter thereof have been increased properly so as to withstand pulling unintentionally.
In another conventional network of ornamental lamp strings as shown in FIG.
8
, it comprises a plurality of twisted lamp strings to be connected with a main power-supply cable; all the lamp strings are hung under the main power-supply, and the sockets of two adjacent lamp strings are arranged in intersection shape, and then the sockets of one lamp string and the power-supply wire of an adjacent lamp string are fastened together by means of claspers so as to form into a network of ornamental lamp strings; finally, a socket on the tail end of every two adjacent lamp strings will be unable to hold stably as a result of the intersection arrangement, and that socket is subject to swaying in the wind.
SUMMARY OF THE INVENTION
The prime object of the present invention is to provide a network of ornamental lamp strings, in which the main power-supply cable is connected with several lamp strings on one side thereof; all the lamp strings have the same length and the same number of sockets arranged at a regular distance. The sockets between two adjacent lamp strings are connected together by means of a knitting cord so as to knit all the lamp strings into a network of ornamental lamp strings.
Another object of the present invention is to provide a network of ornamental lamp strings, in which every lamp string in the network is knitted with a knitting cord, and then all the sockets of the lamp strings are arranged in a regular order, and the edge thereof is knitted with a knitting cord without copper wire to form into an edge of the network so as to facilitate the same to be hung in place.
Still another object of the present invention is to provide a network of ornamental lamp strings, in which every lamp string is twisted with two power-supply wires, and the tension force of every lamp string is within a safety limit; after the lamp strings are knitted into a network, the tension force of each lamp string will not be affected.
A further object of the present invention is to provide a network of ornamental lamp strings, in which all the lamp strings have the same length, and are connected to one side of the main power-supply cable; all the lamp strings are knitted into a network of ornamental lamp strings, and such a network is simple and easy in terms of mounting in place.
