Title:
AUTO-LEVELING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/061121
Kind Code:
A1
Abstract:
The invention comprises: a headlight (10) equipped to a vehicle (40); a sensor (30) for detecting the inclination in the elevation angle direction of the vehicle (40); and a control unit (20) for controlling the light-emitting state of the headlight (10). The headlight (10) comprises: a first light source (31a) for emitting, from the headlight (10), light having a first optical axis (51); and a second light source (32a) for emitting, from the headlight (10), light having a second optical axis (52) having a different angle from the first optical axis (51) in the elevation angle direction. The control unit (20) performs the control by allowing the ratio between the amount of light from the first light source (31a) and the amount of light from the second light source (32a) to be changed according to the inclination detected by the sensor (30), and modulating the lights from the first light source (31a) and the second light source (32a).
