    • In order to meet the legal requirements regarding color of light from a headlight, especially at the light-dark boundary and how much scattered light can occur in the dark region, a lens (5) is provided, which has a diffractive structure on at least one of its surfaces (8). This lens (5) is built into a headlight with a diaphragm (4) arranged between the lens (5) and a light source (3) so that the diffractive structure is arranged substantially only in a region of the lens surface that is not masked by the diaphragm. In various embodiments a computer-generated hologram (17a-17e) can be arranged in the other region of the lens surface that is masked by the diaphragm, so that the lighting apparatus can perform other functions, such as improving driver visibility, displaying an image, measuring the distance to an object or detecting rain or snow.
    • 为了满足关于来自前灯的光的颜色的法律要求,特别是在浅黑色边界,以及在黑暗区域中可能发生多少散射光,提供了至少具有衍射结构的透镜(5) 其表面之一(8)。 该透镜(5)内置在头灯中,其中设置在透镜(5)和光源(3)之间的隔膜(4),使得衍射结构基本上仅布置在未被遮蔽的透镜表面的区域中 通过隔膜。 在各种实施例中,计算机生成的全息图(17a-17e)可以布置在由光阑遮蔽的透镜表面的另一区域中,使得照明装置可以执行其他功能,例如提高驾驶员可视性,显示 测量与物体的距离或检测雨或雪的图像。

    • The present invention relates to beam shaping elements, such as for example lenses, diffractive elements or mirrors, which exist as composites, comprising an inorganic substrate and an organic substrate in the form of a polymer, which can be thermally cured at temperatures between 0 and 180° C. Preferably, the organic polymer is selected from the group consisting of polyurethanes and silicones. According to a preferred embodiment, it is a polyurethane. The beam shaping elements according to the present invention have advantageous properties with respect to precision, rigidity and durability and can further be produced in an easy way by means of an economic method, which method is also subject of the invention.
