  • Patent number: 6250786
    Abstract: A motor vehicle headlight assembly includes a reflector extending along a focal line and having an open end, a light source including an elongated gas discharge tube extending within the reflector along the focal line for the light issued thereby onto the reflector to be reflected by the latter into the open end, and an at least translucent light-guiding plate spanning the open end of the reflector and operative for directing light passing through it onto an illumination area situated at a predetermined distance in front of the motor vehicle on which the headlight assembly is mounted when in use. The reflector has at least in general the configuration of a flattened cross-sectionally parabolic cylinder and consists at least in part of two opposing regions at least one of which is inclined by a predetermined angle about the focal line with respect to the position it would have assumed in a true cross-sectionally parabolic cylinder.

  • Patent number: 6224245
    Abstract: The headlight has a light source (12), a reflector (10), and a baffle (32) with a light admission opening (34), the baffle being disposed downstream of the reflector (10) in the light exit direction (30). The reflector (10) has a central reflector region (16), by which an at least approximately parallel fractional beam (20) is reflected, and at least one peripheral reflector region (24), by which a fractional beam (28) that converges in horizontal longitudinal planes (22) and is at least approximately parallel in vertical longitudinal planes (18) is reflected. The fractional beams (20, 28) are concentrated at least substantially on the light admission opening (34) of the baffle (32), whose cross section is smaller than the cross section of the reflector (10) at the front edge (36) of the reflector. The beam emerging from the headlight has pronounced horizontal scattering, despite the small cross section of the light admission opening (34) of the baffle (32).

  • Patent number: 5769525
    Abstract: The headlight has a reflector (10) and a light source (12) which is arranged in a lamp carrier (22), which can be pivoted in relation to the reflector (10) about a horizontal axis (30) between a position for low beam and a position for high beam by means of an actuator (42). Starting from the position for low beam, the light source (12) is moved as a result of the pivoting movement about the axis (30), together with the lamp carrier (22), both in the direction of the optical axis (11) of the reflector (10) towards its vertex and also vertically downward in relation to the optical axis (11). Starting from the low beam reflected by the reflector (10) in the case of the arrangement of the light source (12) in its low beam position, the result achieved is both a concentration of the light beam reflected by the reflector (10) and an elevation of the light beam, so that an effective high beam is generated by means of which the remote region in front of the vehicle is illuminated with a high illumination intensity.

  • Patent number: 5690409
    Abstract: A headlight has a light source and a reflector. A screening device is associated with the light source and has a web located at both sides of the light source and extending along the optical axis. A light-impermeable cap forms a part of the screening device arranged under the light source. A gap-like opening remains between the upper edges and the lower edges of the webs. Above the web, light emitted by the light source and reflected from the upper region of the reflector can pass and form a low beam to produce an upper bright-dark limit by the upper edges of the webs. The light passing through the gap-like openings is reflected from the lower region of the reflector and forms an additional light beam arranged at a distance above the bright-dark limit.

  • Patent number: 5672001
    Abstract: 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.
