摘要： A LED driver includes a high frequency inverter and an impedance circuit. The high frequency inverter operates to produce a high frequency voltage source whereby the impedance circuit directs a flow of alternating current through a LED array 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 can be employed to divert the flow of the alternating current from the LED array, or to vary the flow of the alternating current through LED array.

摘要： One form of a traffic light (10, 11) employs one or more LED circuits connected to a voltage source (VS). Each LED circuit includes a series connection of a LED array (30), a current limiter (31) and an electronic switch (32). Each current limiter (31) controls a flow of LED current (IRL) through an associated LED array (30) whenever a switch controller (21) closes the associated electronic switch (32). Another form of a traffic light (60, 61) employs one or more LED circuits connected to a current source (IS). Each LED circuit includes a parallel connection of a LED array (80) and an electronic switch (81). A LED current (IRL) flows through an LED array (80) whenever a switch controller (71) opens the associated electronic switch (81).
