本说明书中，如果没有特殊说明，单数型也可以包括复数型。说明书中使用的"包括(comprises)"以及/或"包括的(comprising)"等叙述不排除所涉及到的构成要素、阶段、动作，以及/或元件、一个以上的其他构成要素、阶段、动作，以及/或元件的存在或添加。
图1为本发明一个实施方式的汽车头灯构成图。
如图1所示，本发明一个实施方式的汽车头灯包括，固定车灯模块100、旋转车灯模块200、控制部300以及旋转驱动部400。
固定车灯模块100固定在灯罩500内侧(附图右侧)。固定车灯模块100包括第一车灯单元110和第二车灯单元120。
第一车灯单元110照亮汽车前方的远距离领域，生成远光(high)模式。第一车灯单元110可以采用发光二极管(LED)作为光源。
第二车灯单元120位于第一车灯单元110的上方。第二车灯单元120照射汽车前方的近距离领域，生成向下光宽(low wide)模式。第二车灯单元120可以采用发光二极管(LED)作为光源。
旋转车灯模块200位于灯罩500左侧(附图左侧)。即，旋转车灯模块200与固定车灯模块100相比，更靠近车身侧面。
旋转车灯模块200可根据旋转驱动部(400, swivel actuator)的控制，向车宽方向(附图的Z轴为中心)旋转。另外，旋转车灯模块200包括第三车灯单元210和第四车灯单元220，所以第三车灯单元210和第四车灯单元220可以个别的，或同时向车宽方向旋转。
第三车灯单元210包括ADB(adaptive driving beam)车灯单元。第三车灯单元210照射前方远距离领域，可以生成L-Shape模式。因此，通过调节第三车灯单元210照射的光量，或阻断特定领域的光线，防止对面车道的汽车司机产生晃眼。并且，第三车灯单元210可根据对面汽车的行驶路径移动，更有效地防止对面司机的晃眼。另外，第三车灯单元210可以采用发光二极管(LED)作为光源。
第四车灯单元220位于第三车灯单元210的上方，包括DBL(dynamic bending light)车灯单元。第四车灯单元220照射前方远距离领域，生成向下焦点(low focus)模式。因此，汽车行驶在弯曲的道路时，第四车灯单元220向道路的弯曲方向旋转，在汽车前方的近距离确保司机的视野。另外，第四车灯单元220可以采用发光二极管(LED)作为光源。
控制部300控制固定车灯模块100和旋转车灯模块200的驱动，体现驾驶条件所需的光束模式。必要的光束模式有，近光灯(low beam)、远光灯(high beam)、DBL以及ADB。
为了体现这种光束模式，按照控制部300发出的信号，固定车灯模块100和旋转车灯模块200的第一至第四车灯单元110, 120, 210, 220可以个别亮起或关闭。 
另外，控制部300还控制旋转驱动部400。旋转驱动部400旋转旋转车灯模块200，体现ADB和DBL光束模式。旋转驱动部400可以包括，线性马达和动力传递模块。并且，第三车灯单元210和第四车灯单元220连接在动力传递模块，可以分别通过线性马达旋转。
如上所述，第一至第四车灯单元110, 120, 210, 220的亮灯和灭灯，以及第三车灯单元210和第四车灯单元210, 220的旋转组合在一起，可以体现必要的光束模式。
如图2所示，所要求的光束模式为近光灯(low beam)时，只有第二和第四车灯单元120, 220亮灯。此时，车灯照射汽车前方的近距离，所以能获得如图2所示的路面模式。
如图3所示，所要求的光束模式为远光灯(high beam)时，第一至第四车灯单元110, 120, 210, 220全部亮灯。此时，车灯照射汽车的近距离和远距离领域，所以能获得如图3所示的路面模式。
如图4所示，所需的光束模式为DBL和ADB时，第二至第四车灯单元120, 210, 220亮灯。此时，车灯照射汽车前方的近距离和远距离领域，可以获得如图4所示的路面模式。此时，根据需要上下移动(leveling)第二车灯单元120或关掉第二车灯单元120。
如上所述，按照本实施方式， 组合第一至第四车灯单元110, 120, 210, 220的亮灯和灭灯、以及第三车灯单元210和第四车灯单元210, 220的旋转，可以体现各种光束模式。
另外，本实施方式中，第三车灯单元210和第四车灯单元220可以连接在一个旋转驱动部400旋转。此时，与各个车灯单元都具备旋转驱动部相比，减少部件数，节省相应的成本。
另外，本实施方式中，即使第三车灯单元210旋转，第二车灯单元处于固定状态，所以有助于稳定地确保近距离领域的视野。
以上的说明只是用来说明本发明的技术思想，在本发明所属的技术领域掌握一般知识的从业人员，在不超出本发明的本质特性的范围内，都可以进行各种修改、变更和置换。因此，本发明中所述的具体实施方式和附图并不是为了限定本发明的技术思想，而是为了说明的便利。因此，这些实施方式和附图并不会限定本发明技术思想的范畴。本发明的保护范围以权利要求为准，在同等范围内的所有技术思想都应被视为包括在本发明的权利范围。
