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. |
