LOAD DETERMINATION DEVICE AND ILLUMINATION APPARATUS USING SAME |
摘要 |
An illumination load determination device includes an illumination load; a voltage applying unit for applying a voltage to the illumination load; a connection unit for connecting the illumination load and the voltage applying unit; a detection unit for detecting at least one of a current flowing through the illumination load and a voltage across the illumination load when the voltage is applied to the illumination load from the voltage applying unit via the connection unit; and a determination unit for determining a type of the illumination load based on an output from the detection unit. The determination unit has a comparator for comparing a detection value detected by the detection unit to a predetermined threshold, and determines that the illumination load has a capacitance based on an output of the comparator. The voltage applying unit lights on the determined illumination load with a rated driving voltage.
