Abstract

A flexible decorative lamp system including a plurality of lamp strips and a plurality of connectors adapted to connect each two lamp strips in series, wherein each connector includes a cylindrical connector body having a longitudinal center through hole of triangular cross section, two terminal elements connected together and mounted in the connector body, and two screw caps respectively fastened to two opposite ends of the connector body to hold two lamp strips in connection to the terminal elements at two opposite sides; the lamp strips have a triangular cross section fitting the longitudinal center through hole of the cylindrical connector body.

Claims

1. A flexible decorative lamp system comprising a plurality of lamp strips and a plurality of connectors adapted to connect each two lamp strips in series, wherein:

each of said connectors comprises a cylindrical connector body, a first terminal element, a second terminal element, and two screw caps, said cylindrical connector body having two threaded split extension tubes longitudinally aligned at two opposite ends, and a longitudinal center through-hole of triangular cross section, said first terminal element and the second terminal element being connected together and mounted inside the longitudinal center through-hole of said cylindrical connector body, said first terminal element having a plurality of male terminals at one end adapted for fastening to one terminal element of one lamp strip, and a plurality of female terminals at an opposite end, said second terminal element having male terminals at two opposite ends respectively fastened to the female terminals of said first terminal element and one terminal element of one lamp strip;

each of said lamp strips is comprised of a transparent, flexible, elongated shell having a triangular cross section adapted to engage into the longitudinal center through hole of one of said connectors, a light string installed in said shell, and two terminal elements respectively connected to two opposite ends of said light string and integral with two opposite ends of said shell.

2. The flexible decorative lamp system of claim 1, wherein the shell of each of said lamp strips is provided with at least one V-cut passing through a wall of the shell, at which the respective lamp strip can be bent at right angles to fit over a corner of the wall.
