Abstract: The present invention is directed toward a light module for a motor vehicle headlamp having a primary lens which conducts light emitted by a light source to an intermediate light distribution, wherein an aperture shutter is disposed in relation to a secondary lens such that light in the intermediate light distribution, which passes by the aperture shutter on a first side of the aperture shutter, ends up in a first beam path in a region lying on a first side of the light/dark border in the second light distribution. The primary lens deflects a portion of the light emitted from the light source, such that it passes by the aperture shutter on a second side of the aperture shutter, and is distributed by the secondary lens in a second beam path in a region lying on a second side of the light/dark border in the second light distribution.

Abstract: A headlight for a motor vehicle composes at least two semiconductor-light sources and a plurality of light refractors and/or reflecting optics. Light of each of the semiconductor-light sources is directed into a front area of the headlight such that the light produces at the front area a rule-consistent light distribution. An illuminated section of the light distribution of a first of the semiconductor-light sources is not identical with an illuminated section of a second of the semiconductor-light sources. The first semiconductor-light source defines a first construction type and the second semiconductor-light source defines a second construction type. The first construction type defines higher luminous flux and lower efficiency relative to luminous flux and efficiency defined by the second construction type.

Abstract: The present invention relates to a method for performing pre-exposure and curing of a photo-sensitive material for optical data storage, in particular for holographic data storage, and to an apparatus for writing to optical storage media using such method. According to the invention, for pre-exposure and/or curing of an optical storage medium the optical storage medium is illuminated by a coherent light beam emitted by a light source, which is also used for data recording. Pre-exposure and/or curing is performed in one or more exposure steps, in which the coherent light beam carries a data pattern, the exposure dose for each exposure step being smaller than a minimum dose such that the diffraction efficiency of the recorded data pattern is too low to distinguish data from noise.
