摘要： A driver circuit for a semiconductor light-emitting element enables stable dimmed lighting from very low luminance output to rated luminance output by use of a switching power source operating in a discontinuous mode. The driver circuit includes a DC-DC converter, an output sensor, and a feedback controller. The DC-DC converter includes a burst dimming controller for intermittently stopping an ON/OFF operation of a power switch of the DC-DC converter, thereby reducing a current flowing to the semiconductor light-emitting element. The output sensor detects at least one of the current provided to the semiconductor light-emitting element or the voltage of the semiconductor light-emitting element. The feedback controller adjusts an ON time of the power switch during the ON/OFF operation such that a detected value of the output sensor approaches a target value. Near a dimming control lower limit, power is blocked from the feedback controller.

摘要： An LED lighting device is provided with output impedance control to stabilize an optical output across a wide current range. A switching power supply generates the output current, with switching control circuitry to determine switching frequency and an ON period for an associated switch, and to turn on/off the switch according to the determined frequency and ON period. An impedance element is coupled across output terminals for the lighting device, with an impedance value set so that a load current is larger than a current flowing to the impedance element at maximum on-duty of the switch and a current flowing to the impedance element is larger than the load current at minimum on-duty. The impedance element may be a variable impedance element, wherein an impedance control circuit adjusts the variable impedance such that an impedance value for minimum on-duty of the switch is smaller than that for a maximum on-duty.
