Definitions
- the invention relates to a light distribution assembly with an adjustable diaphragm arrangement for a combined high and low beam headlights, in particular for motor vehicles; with a reflector and a light source, the diaphragm arrangement having a dimming diaphragm and a drive for adjusting the dimming diaphragm.
- a vehicle headlight is known from EP 0 723 108 AI, in which a diaphragm system comprising a fixed and a movable diaphragm is arranged between a reflector and a lens.
- the diaphragm which is fixed in relation to the reflector and the lens, covers the area of the light exit opening of the reflector which is not required for the production of high beam.
- the movable diaphragm is pushed linearly by means of a drive over the upper edge of this diaphragm in order to produce low beam.
- the present invention is based on the problem of developing a light distribution assembly of a combined high and low beam headlamp, in which the aperture system, its suspension and drive consists of a few, simple and low-mass components.
- the components should have high precision, functional reliability and absolute maintenance-free be easy to assemble and adjust and get by with little movement joints and guides.
- the anti-glare diaphragm positioned in front of the light exit opening of the reflector forms part of a diaphragm support guided along the outer side of the reflector.
- the panel support has at least two cantilever arms as joints - at least partially made of resilient deformable material. There is at least one attachment point for each cantilever in the rear outer area of the reflector.
- the panel support comprises a crossbar running below or above the reflector, which is arranged on the panel support outside of the two cantilever arms.
- a drive (130) is mounted, the actuator of which is coupled to the crossmember.
- Such a light distribution assembly is part of a conventional two-headlight system.
- the latter represents a lamp that can produce low and high beams.
- Such lamps generally have single-wire lamps, for example gas discharge lamps. Other lamps are also conceivable. Stepped or angled diaphragm top edges provide for the necessary asymmetry of the emitted dipped beam for right or left-hand traffic.
- the light exit cross-section of the reflector In order to switch between low beam and high beam, the light exit cross-section of the reflector must be covered to different degrees.
- an aperture is used, which is mounted on an aperture support behind the reflector in resilient leaf spring or film joints. With the help of a drive, the cover is opened in front of the light exit opening. or swung away. In the swung-up state, it represents a dimming, while in the swung-down position it is a high beam. Since the aperture mainly functions as a dimming aperture within a regular lamp operating time, the aperture will be named below.
- Linear drives such as electrically operated spindle drives or lifting magnets or comparable linear motors and piezo blocks can be used as the drive for the swiveling movement.
- Appropriate part-turn actuators are also conceivable.
- memory metals can also be used, for example, in the film joint areas.

- the leaf springs (121, 122) load the left-hand traffic aperture (100) with a force component that acts to the right - in the direction of deactivating the left-hand traffic aperture (100).
- the diaphragm plate (101) is delimited by a lower edge (103) which is straight in the middle. Between this lower edge (103) and the upper edge (102) there are three slot-like recesses (114). The webs between the recesses (114) cover the openings in the anti-dazzle device (41) which are produced when the spring supports (47, 48) are produced.
- the left-hand traffic panel (100) has a vertical stop (105) at the left end, which is followed by the sloping lifting slope (107) and a horizontal section (113).

- X 12 CrNi 177 or a comparable material with spring properties is used as the material for both parts.
- Non-metallic materials are also conceivable. The latter are then shaped into the necessary physical shape in another process.
- a lifting magnet (130) is used as the drive for moving the diaphragm support (40) relative to the reflector (10).
- the lifting magnet (130) has a housing (131) which receives a winding and supports a lifting armature (136) protruding from the housing (131) and guides it linearly.
- the housing (131) has a guide on each side protruding from the side housing wall
- the lifting armature (136) when the winding is energized, the lifting armature (136) is pushed out of the housing (131) by a predetermined stroke.
- the lifting anchor (136) has in the area of its free end e.g. a circumferential annular groove (137).
- the drive (130) with its guide webs (133, 134) arranged on the housing (131) is firstly seen from the rear of the reflector between the guide rails (27, 28) of the reflector (10) and the underside of the central section ( 12) inserted.
- the lower edge area (19) serves as the front stop.
- the housing (131) has, for example, on the back of its flattened portion (12) facing side a locking lug (135) with which it locks in a corresponding recess in the reflector (10).
- the left-hand traffic diaphragm (100) is placed on the anti-glare diaphragm (41) of the diaphragm support (40). curious; excited.
- the left-hand traffic aperture (100) is usually located. in the park position.
- the finished diaphragm support (40) is brought from below to the reflector (10) in such a way that the dimming diaphragm (41) comes into contact with the light outlet opening (11).
- the elongated holes (73, 74) of the cantilever arms (65, 66) are located in front of the threaded holes (33, 34) of the cross member (30).
- the diaphragm support (40) is pre-fixed to the reflector (10) without clamping force using screws (77, 78).
- the cross bar (81) of the crossmember (80) is pushed with the two coupling strips (91, 92) of the widenings (85, 86) over the free end of the lifting anchor (136) in such a way that the lifting anchor (136) on both sides two tabs (93, 95) and (94, 96) are in contact and the coupling strips (91, 92) snap into the ring groove (137) at the top and bottom for a positive coupling, cf. Figures 15 and 16.
- the diaphragm support (40) is adjusted relative to the reflector (10) or the cross member (30) using a device (not shown here). To do this, index pins reach into the bores (75, 76) and move the panel support (40) within the scope of the play that the screws (77, 78) have along the elongated holes (73, 74). As soon as the distance between the light exit opening (11) and the anti-glare shield (41) has reached its target value, the Tighten the screws (77, 78). Possibly. a washer is placed between the heads of the screws (77, 78) and the cantilever arms (65, 66), which extends from screw (77) to screw (78).
- the cantilever arms (65, 66) are not deformed in the direction of screw rotation.
- the cantilever arms (65, 66) can be protected against this deformation by stop edges, fixing bolts or the like.
- the mounted panel support (40) is vertical
- the diaphragm support (40) lies against the stop arms (21, 22) via the stop surfaces (115, 116).
- the diaphragm support (40) is deflected further downward with respect to the reflector (10).
- the cantilever arms (65, 66) are more curved than the right-hand traffic setting. Due to the abutment of the stop surfaces (115, 116) on the stop arms (21, 22), the upper edge (102) comes exactly to the level that the upper edge (42) also occupies as part of a right-hand traffic blind.
- the contours of the upper edges (42, 102) are mirror-symmetrical when used in relation to the vertical center plane (9).
- a maximum deformation of the cantilever arms (65, 66) results in the high beam setting.
- the anti-glare diaphragm (41) is swiveled downwards by pivoting the diaphragm support (40), cf. Figures 13 and 14.
- the lifting armature (136) presses the cross member (80) to the rear - partly by bending the tension struts (97, 98).
- the panel support (40) pivots about a fictitious, at least approximately horizontally oriented axis, which essentially runs through the centers of the bending zones (71, 72) of the cantilever arms (65, 66).
- the dimming diaphragm (41) moves in a first approximation on a circular path in front of the light outlet opening.
- the pivoting movement is limited, for example, by the stroke of the actuator (136).
- an elastic stop for the kink region (44) of the anti-glare shield (41) can be arranged on the lower edge (19) of the reflector (10). This then results in vibration and noise damping in the end region of the pivoting movement.
- the panel support (40) swings upwards under the spring action of the cantilever arms (65, 66) onto the stop arms (21, 22). Since the pretension of the cantilever arms (65, 66) is then still large enough and the play of the vertical side parts (61, 62) in the recesses (25, 26) is small enough, there is no overshoot or bouncing of the panel support (40). In addition, the forcibly coupled return stroke of the lifting armature (136) dampens the upward movement.
