摘要： A headlight for motor vehicles is produced so that it has a light source emitting light rays, a reflector which forms by reflection from the light rays emitted by the light source a light beam which is dispersed in horizontal planes and extends substantially parallel in vertical planes. The reflector has an optical axis, the light source is arranged so that its longitudinal axis extends parallel to the optical axis of the reflector. The reflector has an apex region which is formed so that the light emitted from the light source is reflected by the apex region as light rays converging in horizontal longitudinal planes which produce great images of the light source in lateral edge regions of a measuring screen arranged in front of the reflector. The reflector has regions which are located outside the apex region and reflect the light emitted by the light source with increasing distance from the optical axis as light rays which in horizontal longitudinal planes increasingly less strongly converge and produce smaller images of the light source on the measuring screen which form a horizontal light band. All the images of the light source are arranged underneath a bright/dark limit.

摘要： The headlamp has a reflector (10) and a light source (12). Disposed in the ray path of the light reflected from the reflector (10) there is a lens (18), which is received in a mounting (20) and consists of an elastically deformable material. The lens (18) is acted upon by at least one control element (22), by which a force can be applied to the lens (18) in order to deform it. The light passing through the lens (18) is influenced, i.e. deflected in its direction. In the nondeformed state of the lens (18) the light beam radiating from the headlamp exhibits a first characteristic, i.e. direction and scatter, and in the deformed state of the lens (18) the light beam radiating from the headlamp, because of the then different optical effect of the lens (18), exhibits a different, second characteristic.

摘要： The low-beam headlight has a reflector, in which a light source is mounted and a light-permeable disk which has optical elements. Light from the light source is reflected as a light beam by the reflector which would illuminate a region (62) of a measuring screen (60) placed in front of the headlight so that the region (62) has a horizontal light-dark boundary without being effected by or without action of the light-permeable disk. A first part of the light beam reflected by the reflector illuminates a first part (64a,64b) of the screen under boundary lines (65a,65b) inclined relative to the light-dark boundary (63). A second part of the light beam reflected by the reflector illuminates a second part (66) of the measuring screen between the light-dark boundary (63) and the boundary lines (65a,65b). A portion of the first part of the light beam is at least partially deflected by the optical elements of the light-permeable disk so that it produces the higher lying section of the light-dark boundary associated with the vehicle's own traffic side of the light beam from the low-beam headlight after passing through the disk.

摘要： The headlight apparatus has at least one headlight unit which includes several headlight subunits (20;40;60; 61;70;90). A base low beam which illuminates a base region in front of the vehicle is produced by at least one of the headlight subunits (20;40) in such a way as to fulfill the basic minimum requirements for a low beam. Additional headlight subunits (60;61;70;90) are connectable to the headlight subunit (20;40) producing the base low beam. At least one of the headlight subunits (20;70) is constructed according to the projection principle and has a reflector, a light source and, following the reflector, a lens and a diaphragm. At least one of the headlight subunits (40;60;61) is constructed according to a reflection principle and has a reflector, a light source and, if necessary, a light permeable disk with optical elements in it. A concentrated or focused light beam is produced by the headlight unit or units (20;70) constructed according to the projection principle while a horizontally scattered light beam is provided by the headlight subunit or subunits constructed according to the reflection principle.

摘要： A vehicular headlight includes at least one light source that emits light when in use, a reflector having a main reflection surface so positioned relative to the light source as to reflect any light reaching the same from the light source in the form of at least a low light beam delimited at least by an upper light/dark boundary at its upper region as considered in the position in which the headlight is to be used, and a light-transmitting plate extending across the path of the light beam at a distance from the light source and at least substantially devoid of any optically active profiles. A reflection element is further provided that is integral with the reflector and has an additional reflection surface deviating in configuration from that of the basic reflection surface to reflect any light reaching the same from the light source in the form of an additional light beam to an additional region situated upwardly of the upper light/dark boundary.

摘要： The headlight has a light source (10) in the form of a gas discharge lamp and a reflector (12) which has a first reflector part (16) and a second reflector part (18). A converging light beam is reflected from the first reflector part (16) and a lens (26) and a stop (22) with an edge (24) for producing a light-dark boundary are arranged in the path of that beam. The second reflector part (18) is arranged above and/or beside the first reflector part (16) and is moveable between a position for low beam light, in which a light beam directed downward is reflected from it, and a position for high beam light, in which a light beam with a greater range is reflected from it. The light reflected by the second reflector part (18) in the position for low beam light can issue from the headlight and contribute to the formation of the low beam or be absorbed inside the headlight. A completely effective high beam is formed by a combination of the light reflected from the second reflector part (18) with the light reflected from the first reflector part (16) in the operating configuration for the high beam light.
