Multi-Sequenced LEDs on Two or More Wires

摘要

The present invention is generally directed to sequencing two or more LEDs on two or more wires; if more than two wires are used, any two pairs of wires can be used as a pair of wires. Each pair of wires can be used to sequence two or more LEDs, and a sequencer can control sequencing of LEDs on multiple wires connected in a group, or in multiple groups of multiple wires. For a given pair of wires, a first group of LEDs is wired opposite a second group of LEDs so that only one group will emit light at one time depending upon the flow of an alternating current. Two groups of LEDs can also be created by using two different semiconductor materials alternately wired to a single anode and cathode pair of a single LED physical package.

主权项

1. An apparatus, comprising:
a first electrically conductive wire; a second electrically conductive wire; and a plurality of light emitting diodes (“LEDs”), each of which is comprised of a semiconductor material electrically connected to both an anode and a cathode, the plurality of LEDs comprising:
a first group of one or more of the plurality of LEDs, each of which has its anode electrically connected to the first electrically conductive wire and its cathode electrically connected to the second electrically conductive wire; anda second group of one or more of the plurality of LEDs, each of which has its anode electrically connected to the second electrically conductive wire and its cathode electrically connected to the first electrically conductive wire; wherein the semiconductor in the first group is actuated to emit light in the first state but not in the second state while the semiconductor in the second group is actuated to emit light in the second state but not in the first state.
