In-vehicle LED lighting control device and control method of in-vehicle LED lighting control device

摘要

The on-vehicle LED lighting control device outputs a drive voltage obtained by converting a power supply voltage supplied from an input terminal to an output terminal, and a first LED current that is supplied with the drive voltage and is based on the drive voltage. By controlling the supply to the first LED lamp via the LED terminal, a first LED control unit that switches on and off of the first LED lamp, and a drive voltage is supplied, based on the drive voltage By controlling the supply of the second LED current to the second LED lamp via the second LED terminal, the second LED control section for switching on / off of the second LED lamp, and the input terminal When the power supply voltage is supplied to operate, the operation of the conversion unit is started by the activation signal, and the operation of the first LED control unit is controlled by the first control signal based on the operation state of the control switch. And comprises a second control signal for controlling the operation of the second LED control unit, a main control unit.
