  • Patent number: 11964608
    Abstract: A vehicular lamp system includes a light distribution control device that controls a first lamp unit and a second lamp unit. The light distribution control device forms a combined high-illuminance pattern in a region where no target is present. Meanwhile, the light distribution control device forms a combined shading pattern in regard to a forward vehicle. Furthermore, in regard to a specific target, the light distribution control device controls the first lamp unit so as to form an illuminance fixed pattern, controls the second lamp unit so as to form an illuminance fixed pattern or to form an illuminance adjusted pattern, and forms a combined mid-illuminance pattern by superposing the light distribution patterns that the first lamp unit and the second lamp unit form.
