Definitions

  • the invention relates to a projection module for a lighting unit of a vehicle with a reflector, with a reflector associated with the light source, with a releasably connected to the reflector aperture, with a lens-bearing and releasably connected to the diaphragm lens holder and with a releasably connected to the reflector Support frame for connection to a housing of the light unit.
  • a projection module for a lighting unit of a vehicle known, which operates on the projection principle and in addition to a light source and a reflector additionally has a diaphragm and a lens.
  • the light source is arranged in a first focal point of the ellipsoidal reflector and the aperture in the region of a second focal point of the reflector, wherein a blend edge of the aperture is projected as a cut-off line on the road.
  • the lens is held by means of a lens holder, which is connected via a bayonet closure with the reflector.
  • the panel is bolted to the reflector.
  • To connect the reflector to a housing of the lighting unit of the same is connected to a support frame.
  • Object of the present invention is therefore to develop a projection module for a light unit of a vehicle such that with simple means a fast and secure mounting of the projection module is ensured, in particular, an accurate positioning is ensured.
  • the invention in conjunction with the preamble of claim 1, characterized in that the support frame is integrally connected to the lens holder to form a base support member, the positioning on a side facing the reflector positioning means for positioning the shutter and rotary closure means for rotatable connection with a front edge of the reflector.
  • the particular advantage of the invention is that can be significantly reduced by forming a base support member of the cost and installation costs.
  • the base support member incorporates the functions of the support frame and the lens holder and, by providing positioning means and rotary shutter means, additionally enables a reflector and a shutter to be held in a predetermined centered position.
  • the base support part thus essentially forms the only non-optical or non-photovoltaic body of the projection module in addition to the photometric components "light source”, “reflector", “aperture” and “lens”.
  • the rotary closure means of the base support member are formed such that the base support member is connectable via a bayonet with a front edge of the reflector.
  • this can be done by a simple locking or axial support of the reflector on the base support member.
  • a front circumferential flange of the reflector can be fixed to the base support part by means of a flap which can be turned round about an axis of rotation perpendicular to the optical axis thereof. This determination is made after pressing the bayonet lock in the locking position of the reflector and allows accurate centering and positioning of the reflector relative to the diaphragm and the base support member.
  • At least two tabs are provided, which are arranged in each case bendable about a perpendicular or at an acute angle or at an obtuse angle to each other extending axis of rotation.
  • the tab is attached to the flange of the reflector to form two radial incisions in the same.
  • the clamping contact of the tab on the panel allows an electrically conductive connection between the reflector and the panel is ensured, which improves the shielding effect in the case of a formed as a gas discharge lamp light source with connected ignitor.
  • a lighting unit for vehicles is preferably arranged integrated in a headlight of a motor vehicle.
  • the lighting unit can be used to produce a low-beam and / or high-beam distribution or another light distribution.
  • the lighting unit is attached to a housing of the headlight and has essentially a projection module 1, which operates on the projection principle.
  • the projection module 1 essentially comprises a light source, not shown, a reflector 2 assigned to the light source, a diaphragm 3 and a lens, not shown.
  • the reflector 2 is preferably elliptical.
  • the light source is arranged.
  • the diaphragm 3 is arranged with a blend edge 4, by means of which a bright-dark boundary of the light distribution can be projected onto the roadway.
  • a base support member 5 which serves as a support frame for the connection of the projection module 1 to the housing of the headlamp and the other as a lens holder for receiving the lens.
  • the base support member 5 is integrally formed and may for example consist of plastic material.
  • the base support part 5 is tubular and has, on a side facing the reflector 2, a first annular section 6 which has a larger diameter than a second annular section 7 adjoining it directly on a side facing away from the reflector.
  • the second ring section 7 essentially has retaining means for receiving and positionally secure mounting of the lens.
  • the first ring section 6 has circumferentially distributed holes 8 for screw connection of the projection module 1 with the housing of the light unit.
  • the first ring portion 6 further comprises positioning means 9 for positioning the diaphragm 3 on the base support member 5.
  • positioning means for example, positioning pockets 9 'and / or positioning webs can be provided, by means of which the diaphragm 3 can be applied to the first ring portion 6 of the base support member 5.
  • the first ring section 6 has rotary closure means 10, so that the reflector 2 can be locked to the base support part 5 by means of a rotary flange 11 arranged on a front edge of the same.
  • a rotary closure means 10 are circumferentially distributed bead-shaped holding elements which are engaged behind in each case by a radial retaining lug 12 of the reflector flange 11 in a locking position of the reflector 2.
  • the twist lock is designed as a bayonet lock, which allows a quick and secure installation. How out FIG. 2 it can be seen, the retaining lug 12 is still arranged in the non-locking position next to the holding member 10 of the base support member 5. By turning the reflector 2 in the direction of arrow 13, the retaining lug 12 is rotated in the direction of the holding member 10 so that it engages behind this in a locking position, see in particular FIG. 4 ,
  • the reflector flange 11 additionally has two substantially mutually perpendicular lugs 14, 14 '.
  • the tabs 14, 14 ' are each formed by radial cuts 15 of predetermined length on the reflector flange 11. After the reflector 2 has been moved from the non-locking position according to FIG. 2 in the locking position according to FIG. 3 the tabs 14, 14 'are in a position in which they can be transferred or moved in the light emission direction, wherein they comprise edge-side recesses 16 of the panel 3.
  • a rotational axis D1 of the first lobe 14 extends perpendicular to a rotational axis D2, around which the second lobe 14 'can be transferred.
  • the axes of rotation D1 and D2 may also be at an acute or obtuse angle to each other. Characterized in that at least two tabs 14, 14 'is provided, a clear and secure centering of the photometrically relevant components of the projection module 1 can be ensured.
  • the axes of rotation D1 and D2 are substantially tangential to the reflector flange 11 on the one hand and perpendicular to an optical axis 17 of the reflector 2 on the other hand.
