Patent Images
1. An automatic lighting device comprising:
- an illuminance detector for detecting an external illuminance around a vehicle;
a light controller for turning on/off a vehicular light to illuminate an outside of the vehicle, wherein the light controller turns on the vehicular light when the external illuminance is not more than an illuminance threshold;
a driver'"'"'s characteristics detector for acquiring information about a driver'"'"'s physical characteristics; and
a threshold setting element for setting the illuminance threshold in accordance with the driver'"'"'s physical characteristics.
