Title:
ONBOARD LED LIGHTING CONTROL DEVICE AND METHOD FOR CONTROLLING ONBOARD LED LIGHTING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/116460
Kind Code:
A1
Abstract:
This onboard LED lighting control device comprises: a conversion unit for outputting to an output terminal a driving voltage obtained by converting the power supply voltage supplied from an input terminal; a first LED control unit, which is supplied with the driving voltage, for switching on and off a first LED lamp by controlling the supply of a first LED current based on the driving voltage to the first LED lamp via a first LED terminal; a second LED control unit for switching on and off a second LED lamp, which is supplied with the driving voltage, by controlling the supply of a second LED current based on the driving voltage to the second LED lamp via a second LED terminal; and a main control unit which, when supplied with the power supply voltage from the input terminal and operated, starts the operation of the conversion unit by means of a starting signal, and controls, on the basis of the operating state of a control switch, the operation of the first LED control unit by means of a first control signal and the operation of the second LED control unit by means of a second control signal.
