Abstract:
PROBLEM TO BE SOLVED: To provide a driver circuit of a light-emitting element capable of driving the light-emitting element at high efficiency, a high power factor and high stability without a flicker.SOLUTION: A first light-emitting element 4, a reverse electromotive voltage generation unit 6 and a second light-emitting element 5 are sequentially and serially connected as a load. After an alternating current power supply 1 is rectified to a direct current power supply by a rectifier 2, a current is limited to a constant power by an overcurrent protective device 3, and flows to the first light-emitting element 4 or the second light-emitting element 5. The reverse electromotive voltage generation unit 6 generates reverse bias, so that an operation voltage of the first light-emitting element 4 or the second light-emitting element 5 can be reduced. As a result, in the driver circuit of the light-emitting element, driving efficiency and power factor can be increased.
