Abstract
An automotive lamp includes a variable light distribution lamp and a controller. When a first light distribution pattern is to be changed to a second light distribution pattern, and when a difference in the number of shaded portions between the first light distribution pattern and the second light distribution pattern is one, the controller switches a control method for gradually changing the light distribution pattern according to a position relation between the shaded portions included in the first light distribution pattern and the shaded portions included in the second light distribution pattern.
Claims24
An automotive lamp comprising:
- a variable light distribution lamp;
- and
- a controller structured to control the variable light distribution lamp such that the variable light distribution lamp forms a light distribution pattern indicated by control data,
- wherein, when a first light distribution pattern is to be changed to a second light distribution pattern, the difference in a number of shaded portions between the first light distribution pattern and the second light distribution pattern being one, the controller switches a control method for gradually changing the light distribution pattern according to a position relation between the shaded portions included in the first light distribution pattern and the shaded portions included in the second light distribution pattern.
An automotive lamp comprising:
- a scanning lamp structured to scan a beam in a horizontal direction in a first range of θ1 to θ2;
- and
- a non-scanning lamp structured to illuminate a second range of θ3 to θ4 (θ1<θ3<θ2<θ4) a part of which overlaps the first range of θ1 to θ2,
- wherein a lighting-off range of θ5 to θ6 is determined so as to satisfy a relation θ3<θ5<θ6<θ4,
- wherein, in a case in which one end of a shaded portion is to be moved toward a target position θREF (>θ5) from an initial position θINIT (<θ3), when the one end of the shaded portion reaches the lighting-off range of θ5 to θ6, the non-scanning lamp is turned off.

- wherein a lighting-off range of θ5 to θ6 is determined so as to satisfy a relation θ3<θ5<θ6<θ4,
- wherein, in a case in which one end of a shaded portion is to be moved toward a target position θREF (<θ3) from an initial position θINIT (>θ2), when one end of the shaded portion deviates from the lighting-off range of θ5 to θ6, the non-scanning lamp is turned on.
