LIGHTING CONTROL POWER SOURCE AND INSPECTION SYSTEM

WIPO Patent Application WO/2018/021285

A1

In order to provide a lighting control power source which is capable of setting a stroboscope light emission state with two independent parameters and for which a control delay is unlikely to occur even if the parameter settings are changed, the present invention comprises: a reception unit 21 that receives setting values for the stroboscope light emission width and a lighting ratio within the stroboscope light emission width; a stroboscope light emission width control device 24 that outputs an ON/OFF signal by which the stroboscope light emission width setting value is set as a continuous ON period, and controls the length of the period in which an LED lighting device 1 can emit stroboscope light; a lighting ratio control device 25 that outputs an ON/OFF signal set such that the ratio of the ON period and the OFF period, during the period in which the LED lighting device 1 can emit stroboscope light, is the set value for the lighting ratio, and controls the lighting ratio; and a multiplier 28 to which is input the respective ON/OFF signals of the stroboscope light emission width control device 24 ad the lighting ratio control device 25, and which outputs, to the LED lighting device 1, a final output signal obtained by multiplying the ON/OFF signals.
