A headlight for a vehicle has a holder, at least one reflector displaceably supported on the holder, an adjusting device for displacing the reflector and including an adjusting screw having a thread and a displaceably guided transmission element which is articulately connected with the reflector and with the adjusting screw so that during turning of the adjusting screw the transmission element is displaced in a longitudinal direction to displace reflector. The transmission element disengages from the thread of the adjusting screw in the longitudinal direction after the transmission element has reached a predetermined maximum longitudinal displacement, but after a smaller displacement it abutts against at least one abutment, so that during a further movement of the transmission element until the transmission element disengages from the thread of the adjusting screw, a return force is produced which loads the transmission element in an opposite longitudinal displacement direction.

Headlight for vehicle

A light for a vehicle has a reflector, a light source, a light-permeable disk covering a light outlet opening, the reflector having a central region which surrounds the light source and a lateral region, the central region of the reflector having a lateral opening through which a light emitted by the light source can reach the lateral reflector region, the lateral reflector region having at least in one zone a plurality of stepped reflection profiles, the lateral reflector region having an upper edge and a lower edge, at least one reflection segment arranged near one of the edges so that a light emitted from the light source impinges on the reflection segment through the opening of the central reflection region, the reflection segment having a greater extension than the reflection profile at least in a horizontal direction.

Light for vehicles with stepped lateral reflector region

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.

Low/high beam headlight for vehicles

The headlamp has a housing (10) to whose front edge there is a fastened a transparent cover (20) made of plastic. The cover (20) has a surrounding edge region (42) over whose front end it comes to bear against the housing (10). Formed, in a manner such that it surrounds the edge region (42) with clearance, on the cover (20) is an outer edge (46), the free end of which points counter to the assembly direction (17) of the cover (20), which outer edge is elastically deformable toward the edge region (42) and has a plurality of outwardly protruding lugs (48) distributed over the circumference of the cover (20). A wall (28), surrounding the outer edge (46), of the housing (10) has a plurality of recesses (32) which are distributed over its circumference and into which the lugs (48) are latched. The outer edge (46) thus forms a stable latching element and, in addition, causes the cover (20) to be highly rigid.

Headlamp for vehicles

A headlight for vehicles has a light source, a reflector having at least two different reflector regions including a first reflector region which reflects a light emitted by the light source as a converging light beam to form low beam and a second reflector region formed so that light emitted by the light source and reflected by the second reflector region together with the light emitted by the light source and reflected by the first reflector region form high beam, a lens arranged after the reflector in a light outlet direction so that at least the light which forms low beam passes through the lens, and a screening device arranged between the reflector and the lens, the screening device having a stationary screening part and a movable screening part, the movable screening part being movable between a position for low beam in which light forming low beam can pass along the movable screening part and a position for high beam in which additionally the light reflected by the second reflector region can pass along the movable screening part at least partially, so that in the position for low beam an edge of the screening device forms a bright-dark limit of low beam, the screening parts each having a plurality of openings formed so that in the position of the movable screening part for low beam the movable screening part covers the openings of the stationary screening part, and in the position for high beam the openings of the movable screening part coincide with the openings of the stationary screening part at least approximately so that the screening device forms throughgoing openings for the light.

The headlamp has a headlamp insert (10), which is mounted pivotably at its front marginal region (22) in a portion (26) of a receiving fixture (12) and which is acted upon, at a distance from its bearing point, by an adjusting device. The receiving fixture portion (26) surrounds the headlamp insert (10) on its periphery and between the headlamp insert (10) and the receiving fixture portion (26) there is clamped an elastically deformable element (29) in the form of a ring. By means of the ring (29), the headlamp insert (10) is mounted pivotably without play in the receiving fixture portion (26). Changes in distance which, upon a swivel motion of the headlamp insert (10), arise between this and the receiving fixture portion (26) are counterbalanced by the ring (29) and this ring, together with the receiving fixture portion (26), constitutes a very simple mounting for the headlamp insert (10).

Vehicle headlamp

A headlight-light unit for a vehicle mountable in a receptacle of the vehicle has a headlight provided with a headlight housing, a light provided with a light housing and releasably connectable with the headlight, at least one springy locking element arranged on one of the housing, and a holding element on which the locking element is arrestable, the holding element being mountable on the other housing and bringable to different positions along a mounting direction of the light on the other housing.

Headlight-light unit for vehicle

The headlamp has a headlamp insert (10), which is mounted pivotably at its front marginal region (22) in a receiving fixture (12). A part (50) of the receiving fixture (12) has an opening (52) through which there is placed from above an adjusting screw (54), which is supported by its head (55) against the top side of the receiving fixture part (50), which is screwed into a threaded bore (43) in the headlamp insert (10) and onto which there is screwed, between the headlamp insert (10) and the receiving fixture part (50), a female part (57). The female part (57) enables the adjusting screw (54) and hence the headlamp insert (10) to be fixed to the receiving fixture part (50) and, once the female part (57) is loosened, the adjusting screw (54) can be twisted in order to adjust the alignment of the optical axis (28) of the headlamp insert (10) in a vertical longitudinal plane.

The headlamp having a housing in which a reflector is arranged adjustably and the light exit opening of which is covered by a covering plate. In the region of the light exit opening of the housing there is arranged a covering device which has a fastening portion held in the housing and an edge portion which projects from said fastening portion counter to the light exit direction. Formed between the edge portion and the fastening portion is a clearance into which the front edge of the reflector projects, a distance which is required for the adjustment of said reflector being maintained from these parts. From outside the housing, when looking through the covering plate, no gap is visible between the front edge of the reflector and the inside of the housing.

A headlight for a vehicle has a housing having a light outlet opening, a transparent light disc covering the light outlet opening, at least one reflector arranged in the housing and provided with a reflecting inner surface so that the reflector being turnable relative to the housing at least in a vertical plane, and a water level for controlling an inclined position of the reflector and visible through a part of the light disc from outside of the headlight. The water level is arranged in the region of the reflecting inner surface of the reflector and visible through a region of the light disc which extends over the light outlet opening of the housing transverse to the direction of light exiting the headlight.

Headlight for vehicles

The device for testing angular inclination of a headlight (11) has a inclination-detecting device (14) structured as a bubble level connected with the reflector (13) of each headlight and an additional inclination-detecting device (20), which is mounted on the chassis of the motor vehicle. The inclination-detecting device (14) of the headlight indicates the deviation of the reflector (13) from horizontal. The additional inclination-detecting device (20) indicates the inclination of the motor vehicle in a vertical plane (22). To test the inclination or orientation of the reflector from a set value, the reading of the inclinaiton-detecting device (14) is compared with the reading of the additional inclination-detecting device (20). The inclination of the reflector (13) is correct, when, preferably, the inclination-detecting device (14) on the reflector indicates the same deviation from horizontal as the additional inclination-detecting device (20). With the device the inclination of the reflector can also be tested, when the motor vehicle is on a slope.
