Definitions

  • the invention is based on a suitable for a motor vehicle headlights Halogen incandescent lamp according to the preamble of claim 1. Furthermore, the invention relates also a headlight for dipped and high beam with reflector and lamp according to the Preamble of claim 5.
  • EP-A 684,420 shows a halogen bulb with two axis-parallel Luminaires and a reflector with at least partial open space contour.
  • H4 lamps as for example from the DE-OS 26 51 643 are known. It is within the lamp envelope a Dipped beam and a high beam headlamp each arranged axially. Of the Dipped beam is embedded in a dimming cap so that the cap is almost forms a half shell, so azimuthal spans an angle of almost 180 °. The The anti-dazzle device is pulled up at the socket-side end of the low-beam headlight that it shades the high beam light body.
  • the dimming is through Projecting their side edges on the reflector to achieve the cut-off line responsible.
  • an asymmetrical illumination of the road is sought, the is achieved in that the one side of the dimming not quite up to the level of the Low beam is raised, but ends about 15 ° below, so that the of the dipped cap spanned angle is only 165 ° (DE-OS 15 89 242).
  • the main beam can also be a transverse spiral instead of an axial spiral.
  • the utilization of the reflector is limited.
  • the loss due Shading by the dimming cap is on the order of 40% of the total solid angle in the case of the dipped beam. Reverse use only about 40% of the solid angle for the high beam, while about 60% of the solid angle uncontrolled to illuminate the Contribute near field by the light of the high beam in the for the low beam imaginary part of the reflector is scattered.
  • the associated reflector is usually composed of two paraboloid parts, see, for example, DE-OS 27 20 956. Isolated, however, are also Open space reflectors used as u.a. in DE-OS 38 08 086 and EP-A 282 100 are described.
  • the inventive concept but also for modern Lighting functions that are designed variably and meet special requirements.
  • the motor vehicle headlight according to the invention consists of a reflector, defining an optical axis, and a two filament incandescent lamp disposed therein, wherein the first filament, in the following main filament called axially arranged and acting as a shading metallic Cap is partially surrounded.
  • the term axial means in this Context that the helix within sufficiently close tolerances in the optical axis is located.
  • the Main coil is located outside the axis of the lamp bulb. More accurate said, it is located in the reflector below the piston axis. This prevents glare from mirror images.
  • the reflector consists of two segments, the different contours have, wherein the first segment optically substantially the Main coil is assigned, while the second segment optically exclusively from the second luminous element, hereinafter referred to as secondary filament, is served.
  • At least the contour of the first segment is one Open space contour, the principle of which, for example, in DE-OS 38 08 086 and EP-A 282 100 is described. These two writings are explicit Referenced.
  • the second segment of the reflector is an open space contour.
  • the contour of the first segment is preferably optimized so that It creates the necessary for the dimming effect light-dark boundary.
  • the basic principle is that the cut-off line is not covered by illustration to create the edges of a dimming cap or aperture but by a suitable superposition of a variety of images the main coil acting as dipped beam.
  • the light-dark border is generated by the upper edges of the spiral images, the lower edge correspond to the helix.
  • the cut-off line by separate means, such as an aperture.
  • the main coil is surrounded by the shader so that an azimuth angle is shaded from about 100 ° to 140 °, whereby in relation to the Main coil in the reflector a shadow zone and a lighting zone is defined.
  • the Abschatter is there, as of the technology of the Abblendkappen known, arranged so that it is in the reflector below the Main coil is arranged. But he does not have the cut-off line its positioning and dimensioning is less critical than in Trap of a dimming cap.
  • the secondary spiral is arranged in the reflector just below the optical axis, where the offset (relative to the middle of the secondary spiral) between 0.25 times and twice the diameter of the auxiliary spiral is.
  • an offset is about 0.5 times Diameter.
  • the auxiliary spiral can be arranged axially.
  • the secondary spiral is arranged transversely to the optical axis, because then the radiation characteristic of the secondary spiral optimal can be matched to the two-part contour of the reflector. Especially This allows only horizontal luminaire projections generate in the second reflector segment, which are very good in the desired Let the light distribution for the remote lighting be implemented.
  • the spatial distribution of the two segments of the reflector is approximately on the two zones defined by the shader are tuned. It means that the first segment, which essentially processes the light from the main coil, is significantly larger than that served exclusively by the auxiliary spiral second segment.
  • both segments are exemplary a circular reflector opening is assumed - cutouts, the Pieces of cake are similar and together form the whole pie (corresponding to an azimuth angle of 360 °).
  • the second segment is spanned by an azimuth angle, which is approximately the azimuth angle of Abschatters corresponds.
  • the azimuth angle of second segment because of partial shade effects slightly smaller than that of the shading to choose, in particular up to 20% smaller. He is typical, for example 10% smaller.
  • the shading is arranged substantially below the main coil. He is formed so that the secondary spiral at least predominantly in the Shadow zone lies. Its basic shape can be rectangular. she can but also, for example, in a rough approximation as spoon-like or coat-like to get voted. In this case, he owns a frontal tip, which between Secondary and main spiral is arranged, two straight or curved Margins (roughly parallel to the main helix) and a transverse to the side edges extending end edge or a blunt end tip.
  • the shading of the secondary spiral is essentially by the Frontal tip of the spoon or coat of arms causes. She can to this Purpose be upended and / or extended.
  • the shading device may be an originally planar sheet metal part that is continuous is curved concave or at the plane sections angled to each other are set. Such a form is material-saving, easy to manufacture and low-reflex.
  • the sheet metal part can also be curved concave in particular, it is then spoon-shaped or shaped like a crest.
  • the falling in the shadow zone Radiation of the secondary coil targeted under reflection on the second segment to produce a usable as an essential part of the long-distance lighting used in intense light beam.
  • This arrives Part of the radiation of the secondary spiral also in that for the Mau Listel not covered first reflector segment.
  • This radiation does not deliver here significant stray radiation, but rather in high beam operation used as an additional contribution to the side illumination.
  • the low beam is switched off.
  • the electric power the auxiliary spiral about the same size as that of the main coil. she can also be a little bit larger, generally up to 40%. In a typical Power of the auxiliary coil of 60 W, the luminous flux is about 200 lm.
  • the lamp is a halogen incandescent lamp, since their dimensions are very small and their lifespan is very high.
  • the area proportion of the shadow zone assigned second segment of the total area of the reflector about 10 to 30%.
  • the useful luminous flux obtained from the second segment is preferred at least 80 lm.
  • a typical power of the main coil is 50 to 70 W.
  • connection between the electrical connections of the two luminous bodies switched so that the main coil acts as a low beam, while the high beam from the superposition of the main and secondary spiral simultaneously emitted light is formed.
  • the novel concept presented here can also be used for others Applications, especially for the term AFS (Advanced Frontlighting Systems) summarized applications, the subject Eureka Project 1403.
  • the achievable light distributions are characterized by the fact that they use an improved Technique better and / or more flexibly adapted to different traffic situations are defined as the dimmed light distributions specified in rigid standards and high beam.
  • An example is the adjustment of the cut-off line to the speed of travel.
  • the individual coils can be operated individually in the usual way be or additionally interconnected. In the latter case So then are three (or more) different modes of operation feasible. Instead of the usual light distributions, the classic modes of operation "High beam” and “low beam” correspond, so are very good too novel light distribution patterns feasible, the modern modes of operation like "city light”, “highway light”, “highway light”, “traffic light” et al correspond. Such an operation is for example in DE-OS 41 24 374 explained. The advantage of the technology presented here In particular, this is because it allows it to be used in modern lighting systems, which offer a variety of different functions, still keep the number of required headlights low.
  • cut-off lines can also be realized by fading.
  • both coils are designed either with approximately the same power or they are designed so that the power of the auxiliary coil between 20% and 80%, in particular about 50%, corresponds to the performance of the main coil.
  • a horizontal plane can be defined, which includes the main coil and parallel to the secondary coil runs and has its origin in the main spiral.
