摘要： An LED lighting device includes a DC/DC power converter having output terminals coupled to respective lamp sockets. A controller receives signals from a current sensor and a voltage sensor, and controls the DC/DC power converter to increase/decrease an output voltage based on a sensed output current with respect to a target value. A sensed output voltage is compared to predetermined upper and lower limit values, and the DC/DC power converter is disabled when the output voltage exceeds the predetermined upper limit value or falls below the predetermined lower limit. The controller further measures an accumulated lighting time of the device, and after the accumulated lighting time has exceeded a predetermined switching time, decreases the upper limit value monotonously or in increments as the accumulated lighting time passes.

摘要： An LED lighting device includes a power converter for outputting a variable output voltage, two LED lamps being connected in series between output terminals of the power converter; a current detector for detecting an output current from the power converter; a first detector for detecting the output voltage of the power converter and generating a first detection voltage corresponding to the output voltage; a second detector for detecting an applied voltage to one of the two LED lamps and generating a second detection voltage corresponding to the applied voltage; and a controller for controlling the power converter to adjust the output voltage to thereby make the output current coincide with a target value. The controller controls the power converter to decrease the output voltage if at least one of the second detection voltage and the deference between the first and the second detection voltage does not fall within a range.

摘要： An LED lighting device includes a converter for converting a power source voltage into a DC voltage and outputting it to an LED unit; and a controller for controlling an output of the converter. The converter has a chopper circuit including a series circuit of an inductance element and a capacitor; a switching element connected to the inductance element in series and turned on/off by the controller; and a diode as discharging path of the inductance element during an OFF state of the switching element. The controller controls an on/off time of the switching element such that a current supplied to the LED unit during a specific time period after a lighting operation is started becomes smaller than a current supplied to the LED unit in a steady state by using a voltage generated in a secondary coil of the inductance coil as an operating voltage thereof.
