    • A motor vehicle headlight with at least one modulable laser light source (1a . . . 1d), whose laser beam is directed onto a means of light conversion (8) through a pivoting micromirror (7) controlled by a mirror control (9), and with a projection system (12) to project the light image produced by the means of light conversion onto the road, in which at least two laser light sources (1a . . . 1d) are provided that have a laser control (3) assigned to them to modulate the beam intensity, optics (5a . . . 5d) being arranged between each laser light source and the micromirror (7), each forming a laser beam (6a . . . 6d) with a specified beam cross section, the micromirror oscillating about an axis at a fixed frequency, the formed beams of the at least two laser light sources being reflected through the micromirror to form at least two horizontal light bands (10a . . . 10d) lying next to one another on the means of light conversion (8).
    • 一种具有至少一个可调激光光源(1a ... 1d)的机动车头灯,其激光束通过由镜子控制(9)控制的枢转微镜(7)引导到光转换装置(8)上, 以及投影系统(12),用于将通过光转换方式产生的光图像投影到道路上,其中提供至少两个具有激光控制(3)的激光源(1a ...) 向它们调制光束强度,光学器件(5a。.5d)被布置在每个激光光源和微反射镜(7)之间,每个形成具有指定光束横截面的激光束(6a。。6d) 所述微镜以固定的频率围绕轴振荡,所述至少两个激光光源的形成的光束通过所述微反射镜反射,以形成彼此相邻的至少两个水平光带(10a ... 10d) 光转换(8)。
