<p>PURPOSE: An ac led driving circuit is provided to maintain another LED in a serial line by forming a closed circuit through a break over. CONSTITUTION: An AC LED driver circuit includes a plurality of AC LEDs(LD1-LD6). A plurality of AC LEDs are serially connected to each other. The driver circuit comprises one way power path. The driver circuit comprises a plurality of circuits for maintaining a closed circuit. The circuit for maintaining a closed circuit comprises a first semiconductor switching element and a second semiconductor switching element. The second semiconductor switching element forms a power source passing circuit.</p> |
