  • the invention relates to a motor vehicle headlight and / or a motor vehicle rear light with at least one such light module.
  • OLEDs Organic light-emitting diodes
  • these illuminants enable the implementation of customer-specific design requests with regard to special lighting impressions and to display depth effects.
  • the light values which are required for e.g. direction indicators (FRA for short), daytime running lights (TFL for short), rear lights (brake lights, tail lights, rear fog lights, reversing lights) or side marker lights, cannot currently be achieved. This problem is particularly evident when the OLEDs are used in the front area of the vehicle, since, for example, correspondingly high luminous intensity values can be achieved in the direction of travel (HV measuring point).
  • Both the FMVSS and the ECE standards require significantly lower light values in the edge area of the light distribution than in the center.
  • the lower light values in the edge area can already be achieved at the present time thanks to the Lambert radiation pattern of the OLED despite the low luminance.
  • the higher light values in the central measuring points cannot be achieved without switching on additional light sources.
  • One way to counter the above problem is at least partially (see e.g. WO 2011107904 A1 ) to attach additional light sources, such as LEDs with front optics, near an OLED having a predetermined shape.
  • additional light sources such as LEDs with front optics
  • the use of LEDs affects the homogeneity of the radiation.

  • the object of the invention is to remedy the shortcomings of the light modules according to the prior art and to provide a light module suitable for vehicle headlights.
  • This object is achieved according to the invention with a light module mentioned at the outset in that the at least one primary light source is designed as a light rod, the light rod having a multiplicity of deflection prisms, which deflection prisms are set up to transmit the light, which light to the at least one primary light source. Beam of light forms to couple out of the light stick and to direct it in the direction of the secondary light source.
  • the primary light source emits light in a first spectral range and the first layer emits light in a second spectral range, the first spectral range at least partially superimposing the second spectral range.

  • the at least one primary light beam irradiates essentially the entire reflecting surface.
  • the at least one secondary light source or the first layer as an areal, i.e. is formed over a surface extending light source.
  • This embodiment is also particularly advantageous because, with a planar secondary light source, design requirements (for example, according to a large-area, homogeneous lighting impression) and legal standards can be taken into account (with the aid of the primary light source).
  • the at least one secondary light source (2) or the first layer is designed as a planar, planar light source.
  • the at least one secondary light source is designed as a planar curved light source. This alternative is outside the scope of the claims.
  • a homogeneous surface lighting impression can be awakened with both flat and curved secondary light sources.
  • a curvature of the secondary light source will, for example, not lead to collimation of the radiation generated by the secondary light source.
  • the shape of the secondary light source can serve, for example, decorative design purposes.
  • the specified type of light distribution is a direction indicator or a daytime running light.
  • the specified type of light distribution is a tail light and / or a brake light.
  • the light module can be used in a tail / brake light if the light module is arranged in a signal light in a rear area of a vehicle.
  • the first layer is formed in one piece with the second layer.
  • the secondary light source is in one piece, e.g. as an OLED, trained and offers the advantage in terms of installation space.
  • the first layer has two or more light-emitting segments and the two or more light-emitting segments can be controlled independently of one another.
  • Controllable is to be understood here primarily as switching on and off. In addition, this can also be understood to mean the dimming (change in the intensity of the emitted light) of the segments.
  • independently of one another is to be understood to mean that in fact all segments can be controlled independently of one another or that the segments can be controlled in groups independently of one another.
  • each of the two or more light-emitting segments emits light in a predetermined spectral range.
  • Each segment can emit light in a different color and light productions such as "Coming Home” and / or "Leaving Home” can be realized.
  • the second layer has two or more light-reflecting segments.
  • the number of light-emitting segments is equal to the number of light-reflecting segments and each light-emitting segment is formed in one piece with a light-reflecting segment.

  • the at least one OLED is curved.
  • FIG. 1 shows a conventional OLED 1, which is made up of several layers.

  • the anode 50 which mostly consists of indium tin oxide, is usually located on a substrate 55, which can be designed as a glass plate or a PET film.
  • the hole line layer 40 is applied to the anode 50.
  • a further layer, not shown here, can be applied between the anode 50 and the hole conduction layer 40, which layer for Lowering the injection barrier for holes serves and prevents indium from diffusing into the transition.
  • the emitter layer 30 is applied to the hole line layer 40 and normally contains between 5% and 10% phosphor (dye). Less often, the emitter layer 30 consists entirely of the dye.
  • an electron conduction layer 20 is applied between the emitter layer 30 and the cathode 10, which consists, for example, of a metal or an alloy with a low electron work function.

  • the light stick and the OLED (or several OLEDs ( Fig. 7 )) Can emit light in different colors.
  • the term "color” is understood to mean light from a specific predetermined spectral range (or several spectral ranges).
