  • the first support structure has a lens carrier having a light source side end and a projection lens side end.
  • the projection lens side end has a lens mount , which is adapted to receive the projection lens and hold by positive engagement and / or traction.
  • Classic poly-ellipsoidal headlamp modules (PES modules), whose name is derived from the shape of the reflectors used as primary optics, usually have reflectors with internal light source as well as lying in the light flux of the light source and lens elements.
  • modules with semiconductor light sources in particular with light-emitting diodes or laser diodes, which are attached in thermal contact with a heat sink at this. At this usually massive heat sink and the aperture and lenses are attached.
  • the projection lenses of known light modules are mounted in lens carriers by springs, retaining rings, clamps, welding, overmolding and so on. If the known light modules have heat sinks and a lens carrier, this does not contribute to the cooling.
  • the undesired color fringe produced by a projection light module results from the different refractive power of the projection lens for different wavelengths. Whereas the light beams of different wavelengths / colors refracted at different parts of the projection lens overlap in the bright area of the light distribution to white light, a fringing color appears at the light-dark boundary of the light distribution produced by the mirror aperture. With what intensity such a fringe of color appears ultimately depends on Bauteilcommuntoleranzen and mounting tolerances, which affect the distance of the diaphragm edge of the projection lens and the aperture-side cutting width of the projection lens. Under the intersection is the distance from the outer surface apex of the projection lens to the object surface to understand. In the object surface, the diaphragm edge is preferably arranged.

  • the assembly of the projection light module is first simplified.
  • the projection lens can be easily inserted into the lens receptacle of the one component, the holder being completed by adding the second component.
  • Flanging or otherwise reshaping an edge of a lens mount that reduces the diameter of an undivided lens mount after insertion of the projection lens, which is required in undivided lens shots to hold the projection lens used, can be dispensed with.
  • the position of the mirror aperture is fixed relative to the two components of the lens carrier by interlocking positive locking elements, results in a very simple installation of the mirror aperture in conjunction with a very high accuracy of the position of the diaphragm edge with respect to the lens carrier.
  • the clamping attachment also contributes in conjunction with the positive positional fixation to a very low installation costs.
  • the omission of Farbsaumeingnagnagna possible without loss of quality in the low beam reduces the manufacturing cost and production costs, which is an essential development goal.
  • Low cost also contributes to lens attachment without additional parts for standard lens edge geometries.

  • the mirror cover has local matting.
  • the mirror aperture is arranged horizontally so that its diaphragm edge is imaged by the projection lens as a cut-off line of a dimming beam distribution that complies with the regulations.
  • the spacers be so long as to contact the projection lens with a slight bias.
  • a preferred embodiment is characterized in that the second component has two flanges with form-locking elements, which are dimensioned and arranged in mirror image to the flanges and form-locking elements of the first component.
