Definitions

  • the invention relates to a dimmed vehicle headlight with an ellipsoidal reflector, with a light source arranged in the first focal point of the reflector, with a collecting lens inserted in the beam path behind the second focal point and carried by an annular part of a frame connected to the reflector, and with a collecting lens in the beam path arranged in front of the converging lens and in the focal point of the converging lens, the upper, essentially horizontal edge of which produces the light / dark boundary.
  • a dimmed vehicle headlight of this type is known from DE-GM 84 30 629, in which the frame supporting the panel has the shape of a table and connects the reflector, panel and converging lens to form a fixed unit.
  • the converging lens is inserted from below into an opening in the top of the frame and lies with its outer flange on the edge of the opening.
  • the converging lens can be fastened to the frame by gluing or by spring plates that are riveted or screwed to the frame on the outer flange under pretension.
  • the insertion of the converging lens between the legs in the opening of the frame and the attachment of the converging lens by gluing, riveting and screwing is cumbersome and time-consuming.
  • the converging lens attached by riveting or gluing cannot be dismantled. With a screw connection, a secure tight fit of the converging lens is not always guaranteed.
  • the lens can be automatically and simply installed quickly, since the lens can be inserted from the outside into the receiving opening of the frame and can be securely fixed in the frame by means of a simple snap ring.
  • the lens can be removed if the frame is damaged, since it can be pushed out of the ring with great effort.
  • the annular part between the plane formed by the support points and the ring end with the smaller diameter has radially inwardly directed projections, the surfaces of which face each other as centering surfaces for the outer edge of the lens .
  • the lens is centered on the optical axis after insertion into the receiving opening of the frame.
  • the shoulders and the projections are formed from areas that are cut free from the annular part and bent radially inward.
  • a frame made of sheet metal can be produced very inexpensively.
  • the annular part between the largest and smallest inside diameter has the shape of a truncated cone or a spherical section.
  • the snap ring presses the converging lens with a relatively large force against the lugs of the frame which serve as support points.
  • the snap ring bears against the front outer circumferential edge of the converging lens under prestress, and the forces of the snap ring acting on the edge are directed to a common point on the optical axis.
  • the outer circumferential edge of the converging lens, against which the snap ring rests under prestress has a radius or a bevel.
  • the converging lens is fixed by the snap ring not only in the axial direction, but also in the radial direction. By fixing the converging lens in the radial direction, the converging lens is exactly centered on the optical axis.
  • a vehicle headlight which consists essentially of an ellipsoidal reflector 1 and a diaphragm 4 arranged between the converging lens 2 and the reflector 1.
  • the inner reflection surface of the reflector 1 forms a semi-ellipse in the axial longitudinal sections.
  • the filament 3 of an incandescent lamp 5 is arranged, which is supported by an annular lamp holder 6 inserted into the apex opening of the reflector 1 and glued to the rear of the reflector.
  • the incandescent lamp 5 is fixed by a spring 7 which can be placed under prestress on the base plate.
  • a cover cap 8 made of rubber is placed on the annular lamp holder 6.
  • the edge 13 of the diaphragm 4 which generates the light / dark boundary is misaligned with the second focal point of the reflector 1 and is arranged in the focal point of the lens 2.
  • the panel 4 is made in one piece with a cup-shaped frame 9 produced in the deep-drawing process.
  • the cup 9 tapers conically to the bottom surface 10 and carries the converging lens 2 inserted from the cut-out bottom surface 10.
  • Four arm-shaped webs 16 and 17 are cut free from the annular part 12 of the cup 9, the free ends 18 of which are cut by welding the outer circumferential reflector edge 14 are firmly connected.
  • the web 19 cut out of the cup 9 between the webs 17 serves with its free end section angled towards the optical axis as a diaphragm 4.
  • the webs 17 adjacent to the diaphragm 4 serve as diaphragm 4 as support elements, ie after the diaphragm 4 has been adjusted their lateral sections 27 are welded to the support elements 17.
  • the ring-shaped part 12 of the frame 9 is circular and tapers in its inner diameter in the part 11 of its height in the light exit direction.
  • the annular part 12 has the shape of a spherical section between the largest and smallest inner diameter D and d.
  • the converging lens 2 inserted into the annular part 12 from the smaller inner diameter d bears against lugs 30 which are evenly distributed on the circumference and which are cut out of the annular part 12 and bent radially inwards.
  • the end faces 31 of the tongues 30 pointing towards the converging lens 2 serve as support points for the converging lens 2.
  • radially inward projections 33 are introduced into the annular part 12 between the tongues 30.
  • the projections 33 form strips cut free from the annular part 12, the longitudinal direction of which extends perpendicular to the optical axis and which are given an arcuate shape by pressure from the outside.
  • the mutually facing surfaces 34 of the strips 33 serve to pre-center the converging lens 2.
  • a snap ring 15 is inserted from the front between the converging lens 2 and the part 11 which tapers inwardly the annular part 12 .
  • the snap ring 15 presses into a gap formed by the converging lens 2 and the annular part 12 without resting on the bottom of the gap.
  • the snap ring 15 bears against the front outer circumferential edge 35, which has a radius, under prestress.
  • the forces acting on the edge 35 of the converging lens 2 are directed to a common point on the optical axis.
