Patent number: 7387413Abstract: 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.Type: GrantFiled: July 20, 2004Date of Patent: June 17, 2008Assignee: Schott AGInventors: Matthias Brinkmann, Edgar Pawlowski, Wolfram Beier, Rolf Harmgardt
