Vehicle-mounted load controller, vehicle-mounted headlight device, and vehicle-mounted taillight device
First Claim
1. A vehicle-mounted load controller comprising:
- one or more power terminals connected to one or more power lines of a vehicle-mounted DC power supply through a fuse, respectively;
a plurality of load connecting portions connected to a plurality of vehicle-mounted loads, respectively;
switches configured to correspond to the plurality of load connecting portions, respectively, each of the switches starting and stopping supply of power from the power line connected to one of the one or more power terminals to one of the vehicle-mounted loads connected to the corresponding load connecting portion; and
a control unit configured to control the switches in response to inputted control signals, whereintwo or more of the plurality of load connecting portions are electrically connected to at least one of the one or more power terminals, andeach of the switches stops the supply of power from the power line to the load connected to the corresponding load connecting portion when magnitude of current flowing through the load connected to the corresponding load connecting portion reaches or exceeds a predetermined value.

Abstract
A vehicle-mounted load controller is characterized by including: a power terminal connected to a power line through a fuse; load connecting portions to which loads having vehicle-mounted light sources are connected; switches which are provided corresponding to the load connecting portions and which control states of power supply from the power line connected to the power terminal to the light sources connected to the load connecting portions; and a control unit which controls the switches in response to inputted control signals. The vehicle-mounted load controller is characterized in that the multiple load connecting portions to which the multiple light sources for different uses are respectively connected are electrically connected to the power terminal, and that each of the switches stops the supply of power from the power line to the light source connected to the corresponding load connecting portion when the magnitude of current flowing through the light source reaches or exceeds a predetermined value. A rise in lamp voltage during a period from the start of lighting to the establishment of stable lighting is reduced with consideration given to a history of lighting conditions for stable lighting. This produces effects such as increasing the lives of lamps and reducing the frequency of occurrence of arc jumping.
