| Title: |
Rope Light Having a Multi-Circuit Arrangement |
| Abstract: |
A rope light having a multi-circuit arrangement is disclosed. The light
comprises a plurality of 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 coupled in series,
and the first and the second illuminating units in each pair being
connected in parallel. Applying AC source 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. The invention can control on/off of a plurality of
LEDs by means of a relative small number of electrical wires.
