Abstract:
A chasing rope light, comprising:an elongated core tube having an axial tubular cavity; a first, a second and a third 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; and a first and a second illuminating unit, each comprising a diode and at least an illuminator electrically connected together in series and disposed in 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 first 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 second 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 diode of said first and second illuminating units allow opposite direction of said current flow into said illuminating units respectively; and a third illuminating unit comprising at least an illuminator connected between said second conductive wire and said third conductive wire.
