Title:
VEHICLE LAMP TOOL AND METHOD FOR CONTROLLING VEHICLE LAMP TOOL
Document Type and Number:
WIPO Patent Application WO/2018/150995
Kind Code:
A1
Abstract:
A vehicle lamp tool 1 is provided with: a controller 12 that calculates the luminance distribution of a light distribution pattern; an optical device 2 that generates the light distribution pattern in an illuminatable area D; and a first driving circuit 14a that drives the optical device 2. The controller 12 transmits a first light distribution correction signal for correcting the inclination of the current light distribution pattern to the first driving circuit 14a when the inclination angle of a detection signal received from a vehicle height sensor 18 is equal to or less than a threshold value, with respect to the vertical direction of a vehicle. The first driving circuit 14a transmits a first correction driving signal based on the first light distribution correction signal to the optical device 2. The optical device 2 drives an LD 6 and a light deflector 7, and corrects the current light distribution pattern.
