摘要： PROBLEM TO BE SOLVED: To provide a sufficient irradiation against a road surface in front of a vehicle without giving any glare to a driver of a forward driving vehicle and improve the visibility of the road. SOLUTION: Each of a left side lamp 30L and a right side lamp 30R is constituted such that they can selectively irradiate with either one of a left side additional light distributing pattern including an area above a cut-off line of a low-beam light distributing pattern and placed at a left side of a vertical line or a right side additional light distributing pattern including an area at the right side of the vertical line. A vehicle position detecting part 52 detects a position of forward driving vehicle. A sub-shade position determining part 54 controls the left side lamp 30L and the right side lamp 30R in such a way that it may irradiate with either one of the left side additional light distributing pattern or the right side additional light distributing pattern in response to a vehicle position detected by the vehicle position detecting part. The left side lamp 30L and the right side lamp 30R are provided with a shade for shielding a part of light emitted from a light source to form a light distributing pattern for a low beam. This shade is constituted by a sub-shade divided into two segments in a horizontal direction. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a vehicular headlamp device including a rotary shade, having construction for actualizing quick change-over between a high-beam light distribution pattern and a low-beam light distribution pattern.
SOLUTION: The vehicular headlamp device 10 includes a movable shade 34 movable forward/backward relative to the optical axis of a bulb 28, the rotary shade 32 to be rotationally driven to selectively form one of a plurality of light distribution patterns, and a solenoid 38 for moving the movable shade 34. The movable shade 34 interrupts part of the light of the bulb 28 at the forward movement position to form a standard low-beam light distribution pattern. It permits the formation of the other light distribution pattern at the backward movement position. The solenoid 38 moves the movable shade 34 to the forward movement position on a priority basis during non-control to actualize quick change-over between the high-beam light distribution pattern and the low-beam light distribution pattern.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle front headlight having a long-distance increased visibility during a high beam irradiation, to be installed as an unified unit with inclined movement mechanism both for the high beam and low beam irradiation uses. SOLUTION: The low beam light distribution pattern P (L) is formed by lighting the low beam luminaire unit in the case of the low beam irradiation. On the other hand, the high beam light distribution pattern P (H) is formed on imposing the high beam additional light distribution pattern P (H1) by lighting simultaneously the high beam luminaire unit during the high beam irradiation. Besides in the case of the high beam irradiation after the inclined movement unit is shifted by approx. 1.5 degree upwards and the low beam light distribution pattern P (L) hot zone HZ (L) is moved toward the long-distance area of the vehicle-front road surface to increase the long-distance visibility eventually. The luminosity middle position M of the high beam additional light distribution pattern P (H1) is set at approx, 1 degree lower position than the horizontal cut-off line CL1 of the low beam light distribution pattern P (L). Thus, it brings the suitable positioning for increasing the long-distance visibility during the high beam irradiation.
摘要翻译：要解决的问题：为了提供在远光照射下具有长距离增加的可见度的车辆前照灯，作为用于远光和近光照射用途的倾斜移动机构的统一单元安装。解决方案：在近光照射的情况下，通过点亮近光灯具单元来形成近光配光图案P（L）。另一方面，通过在远光照射期间同时照射远光灯具单元，在强光束附加配光图案P（H1）上形成远光配光图案P（H）。此外，在倾斜移动单元偏移了约 1.5度向上，并且近光配光图案P（L）热区HZ（L）朝向车辆前方路面的长距离区域移动，最终增加长距离的可见度。远光配光图案P（H1）的亮度中间位置M被设定为比近光配光图案P（L）的水平切断线CL1低1度左右的位置。因此，它为远距离照射提供了长距离可见度的适当定位。
