Patent ID: 7152999

Claim:
An elongated rope light, comprising: two or more electrical wires longitudinally extended therealong; and one or more pairs of first and second illuminating units, each pair being electrically coupled between any two electrical wires, each illuminating unit including a plurality of LEDs, and the first and the second illuminating units in each pair being connected in parallel, whereby applying an AC between any two electrical wires sequentially will lighten up the first and the second illuminating units in each pair alternately by enabling current to flow through the LEDs in each illuminating unit toward a predetermined direction when the LEDs are conducted, wherein the number of the electrical wires is three and the number of the illuminating units is six, wherein the first illuminating unit comprises a plurality of LEDs between the first and the second electrical wires; the second illuminating unit comprises a plurality of LEDs between the first and the second electrical wires and being in parallel with the first illuminating unit; a positive terminal of the first illuminating unit is electrically coupled to the first electrical wire, and a negative terminal thereof is electrically coupled to the second electrical wire; a positive terminal of the second illuminating unit is electrically coupled to the second electrical wire, and a negative terminal thereof is electrically coupled to the first electrical wire; the third illuminating unit comprises a plurality of LEDs between the second and the third electrical wires; the fourth illuminating unit comprises a plurality of LEDs between the second and the third electrical wires and being in parallel with the third illuminating unit; a positive terminal of the third illuminating unit is electrically coupled to the second electrical wire, and a negative terminal thereof is electrically coupled to the third electrical wire; a positive terminal of the fourth illuminating unit is electrically coupled to the third electrical wire, and a negative terminal thereof is electrically coupled to the second electrical wire; the fifth illuminating unit comprises a plurality of LEDs between the third and the first electrical wires; the sixth illuminating unit comprises a plurality of LEDs between the third and the first electrical wires and being in parallel with the fifth illuminating unit; a positive terminal of the fifth illuminating unit is electrically coupled to the third electrical wire, and a negative terminal thereof is electrically coupled to the first electrical wire; and a positive terminal of the sixth illuminating unit is electrically coupled to the first electrical wire, and a negative terminal thereof is electrically coupled to the third electrical wire.
