Abstract

A chasing rope light includes a flexible core tube, a pair of conductive wires longitudinally extended along the core tube and a pair of illuminating units. Each unit has at least an illuminator and a diode electrically connected together in series and disposed in the core tube. The illuminating units are electrically connected with the conductive wires in parallel such that when a current is applied to the conductive wires, the current is rectified by the diodes so as to alternately pass through the illuminating units for illuminating the illuminators thereof.

Claims

1. A chasing rope light, comprising:

an elongated hollow core tube having an axial tubular cavity;

a first and a second conductive wire longitudinally extended along an outer circumference of said core tube;

a connector provided at one end of said core tube for electrically connecting said conductive wires to a power source;

a first and a second illuminating unit, each of which comprises a diode and at least an illuminator electrically connected together in series and is disposed in said tubular cavity of said core tube for securely holding said illuminators in position, wherein both first ends of said first and second illuminating units are electrically connected to said first conductive wire in parallel and both second ends of said first and second illuminating units are electrically connected to said second conductive wire in parallel, wherein said diode of said first illuminating unit and said other diode of said second illuminating unit are arranged in opposite direction that when a current is applied to said first and second conductive wires, said diode of said first illuminating unit enables said current flowing from said first conductive wire to said second conductive wire via said first illuminating unit, and said diode of said second illuminating unit enables said current flowing from said second conductive wire to said first conductive wire via said second illuminating unit, thereby said diodes of said first and second illuminating units allow opposite direction of said current flow into said illuminating units respectively; and

an outer casing, which sealedly encircles said outer circumference of said core tube and sealedly covers said first and second conductive wires and said core tube to construct an elongated integral rope body to form said chasing rope light.

2. A chasing rope light, as recited in claim 1, wherein said core tube is made of flexible material and each of said illuminators is a LED.
