<p>There is provided a light distribution controller (50) for controlling a light distribution pattern which is formed by light emitted from a vehicle headlamp (1) of a vehicle (C) so as to prevent glare light from being directed to a front vehicle (A, B) existing in front of the vehicle, based on a relative distance between the vehicle and the front vehicle in a vehicle traveling direction. The light distribution controller is configured to control the light distribution pattern so as to block or reduce light directed to a first region (90A, 90B) where the front vehicle is present, when the relative distance is larger than a first value. The light distribution controller is configured to control the light distribution pattern so as to block or reduce light directed to a second region (91) where the front vehicle is present and a third region (92) which is located outside the front vehicle and closer to a road shoulder side, when the relative distance is in a range of a second value to the first value, wherein the second value is smaller than the first value. The light distribution controller is configured to control the light distribution pattern without blocking or reducing light directed to a fourth region where the front vehicle is present, when the relative distance is smaller than the second value.</p> |
