汽车用前照灯
摘要：
本发明提供在近光束不点灯时使远光束点灯而确保车辆前方的能见度、同时对对方来车能够形成不成为眩光的合适配光的汽车用前照灯。在具有近光束照射机构(21a及23)、远光束照射机构(31a及33)、以及切换近光束与远光束的配光切换机构(50)的前照灯中，具有检测不能形成正常近光束的异常状态的异常检测机构(配光切换电路)(50)、以及至少使远光束的光轴(L31)上下倾斜的光轴倾斜机构(40)，在异常检测机构(配光切换电路)(50)检测出异常时，利用配光切换电路(50)将配光切换为远光束。在不能形成正常近光束时，一般使光量大的远光束点灯，确保车辆前方的能见度。
摘要（英）：

In a headlamp comprising low beam irradiating, there are provided main beam irradiating means, light distribution switching means for switching a low beam and a main beam, abnormality detecting means for detecting an abnormal situation in which a proper low beam cannot be formed, and optical axis tilting means for vertically tilting an optical axis of at least a main beam, and the abnormality detecting means detects an abnormality, a light distribution is switched into a main beam by the light distribution switching and the optical axis of the main beam is turned downward by the optical axis tilting means. When a proper low beam cannot be formed, a main beam having a larger light amount is generally turned on to maintain a visibility in of a vehicle and the optical axis of the main beam is turned downward such that glare light is not generated.
