    • PROBLEM TO BE SOLVED: To provide a vehicle lamp having two light sources, capable of switching over of light distribution and improving light distribution of a headlight.SOLUTION: The vehicle lamp includes: a light source 1 having a first light source F1 and a second light source F2; and a reflector 2 for reflecting light emitted from each of the first and second light sources and irradiating it frontward. The lamp further includes: a main shade 5M for shielding a part of the light emitted from the first light source F1 and reflected by the reflector 2 and for obtaining a prescribed light distribution; and a sub-shade 5S for shielding a part of the light emitted from the second light source F2 and reflected by the reflector 2 and further for reflecting it. The light rendering an undesired effect on the light distribution of the second light source F2 is shielded by the sub-shade 5S and the light reflected by the main shade 5M and the sub-shade 5S is superimposed on the light distribution.
    • 要解决的问题:提供一种具有两个光源的车灯,其能够切换配光并改善头灯的光分布。 车辆灯包括:具有第一光源F1和第二光源F2的光源1; 以及用于反射从第一和第二光源中的每一个发射的光并将其向前照射的反射器2。 该灯还包括:主色调5M,用于屏蔽从第一光源F1发射并由反射器2反射的光的一部分并获得规定的光分布; 以及用于屏蔽从第二光源F2发射并被反射器2反射并进一步反射的光的一部分的子色调5S。 对第二光源F2的光分布产生不期望的影响的光被副色调5S屏蔽,并且由主色调5M和副色调5S反射的光重叠在光分布上。 版权所有(C)2012,JPO&INPIT
