摘要： A vehicle lamp system includes a camera which generates image information in a front region, a controller which generates a light distribution command for instructing a light distribution pattern based on the image information, a headlight which irradiates the front region such that the instructed light distribution pattern is obtained, and a position calibrator which detects a positional deviation between the camera and the headlight. The position calibrator detects a reference object based on the image information and measures a luminance of the reference object, and when there is a certain difference between a luminance of the reference object obtained from one light distribution pattern and a luminance of the reference object obtained from another light distribution pattern in which a light quantity of only a part is different from the one light distribution pattern, detects the positional deviation using a position of the part.

摘要： A lighting circuit drives a light source including N (N represents an integer of 2 or more) multiple light-emitting elements coupled in series. A bypass switch circuit includes N multiple bypass switches, each coupled in parallel to a corresponding light-emitting element. A constant current driving circuit supplies a driving current stabilized to a target current to the light source. A light distribution controller controls the bypass switch circuit. For a given light distribution pattern, the duty ratio Di(%) is determined for each of the N multiple light-emitting elements. Multiple light-emitting elements are formed as control units having a sum total of duty ratios that is less than 100%. The light distribution controller controls the multiple bypass switches such that the multiple light-emitting elements included in the same control unit are not turned on at the same time.

摘要： 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.
