<p>A LED driver (10) is disclosed. The LED driver (10) includes a high frequency inverter (20) and an impedance circuit (30). The high frequency inverter (20) operates to produce a high frequency voltage source whereby the impedance circuit (30) directs a flow of alternating current through a LED array (40) including one or more anti-parallel LED pairs, one or more anti-parallel LED strings, and/or one or more anti-parallel LED matrixes. A transistor (T3) can be employed to divert the flow of the alternating current from the LED array (40), or to vary the flow of the alternating current through LED array (40).</p> |
