Title:
VEHICULAR LIGHTING CONTROL DEVICE AND VEHICULAR LIGHTING CONTROL DEVICE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2018/073901
Kind Code:
A1
Abstract:
This vehicular lighting control device is equipped with a detection circuit detecting the terminal voltage of a power generator terminal and controlling a control switch element on the basis of the detected terminal voltage. The detection circuit turns-on the control switch element to cause the LED lamp to turn on if the terminal voltage is at a pre-set first threshold voltage or higher, turns-off the control switch element to cause the LED lamp to turn off if the terminal voltage is lower than the first threshold voltage, and forcibly turns-off the control switch element if the node voltage of a node on the power generator terminal side of a rectifying element is lower than a pre-set second threshold voltage.
