    • PROBLEM TO BE SOLVED: To provide an improved headlight capable of enlarging the range of a lighting region without greatly changing lighting conditions in the lighting region near an automobile.
      SOLUTION: The headlight comprises a reflector 1 defining an optical axis (y-y), a refraction element 4, a light source arranged between the reflector and the refraction element, a movable screen 3 having at least two optically active positions where the screen cuts off part of light beams emitted from the light source or reflected by the reflector, including a terminal position and an intermediate position, and at least one position where the screen is stored, a driving member for controlling the position of the screen, and a folder reflector for reflecting part of the light beams to the upper side of the screen located on at least one optically active position. The screen can optically invalidate the folder reflector, when located on the terminal optically active position.

    • 要解决的问题:提供一种改进的前照灯,其能够在不会在汽车附近的照明区域中大幅改变照明条件的情况下扩大照明区域的范围。 解决方案:头灯包括限定光轴(yy)的反射器1,折射元件4,布置在反射器和折射元件之间的光源,具有至少两个光学活动位置的可移动屏幕3,其中屏幕 切断从光源发射或被反射器反射的部分光束,包括终端位置和中间位置,以及屏幕存储的至少一个位置,用于控制屏幕位置的驱动构件,以及 用于将部分光束反射到位于至少一个光学活动位置上的屏幕的上侧的文件夹反射器。 当位于端子光学活动位置时,屏幕可以使文件夹反射器光学无效。 版权所有(C)2009,JPO&INPIT
