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： A lighting device reliably detects a status (i.e., existence or absence) of a load connection, and enables or disables power output based on the detected load connection status. The device includes a DC-DC converter having input and output terminals, and a DC current conducting element coupled across the output terminals. A load terminal is also coupled across the output terminals and configured to receive an LED unit. A load detection circuit coupled between an input terminal and the load terminal detects the connection status of an LED unit via a DC current passing through the load terminal, and controls a switching operation of the DC-DC converter based on the detected connection status. A diode coupled between the load terminal and the DC current conducting element blocks a DC current path from the input terminals to the load detection circuit through the DC current conducting element.

摘要： A lighting device includes a lighting unit which controls a current being supplied to a load, in which light emitting modules, each having one or more semiconductor light emitting elements connected in series, are connected in parallel, to be a constant current; a current detector which detects a current flowing through one of the light emitting modules; and an abnormality detector which compares a detected value from the current detector with an upper limit and a lower limit of a predetermined current range to detect an abnormality in the load. The abnormality detector detects the abnormality in the load if the detected value from the current detector is larger than the upper limit or smaller than the lower limit, and if the abnormality in the load is detected, the lighting unit reduces the current being supplied to the load.

摘要： A lighting device is provided for lighting control of an LED module based on an externally provided dimming control signal. A chopper circuit includes a switch coupled across a DC input and an inductor which receives and stores energy when the switch is turned on, and discharges energy to the LED module when the switch is turned off. A control circuit determines a current value to the switch, and compares the current value to a predetermined value. During normal operation, the switch is turned off when the detected current value reaches the predetermined value and turned back on when inductor discharge has completed. During a dimming operation, the normal operation is intermittently disabled in accordance with the dimming control signal. The dimming control signal may be a low-frequency PWM signal, with the lighting output being dimmed as a result of a duty ratio of the PWM signal.
