Definitions

  • the present invention relates to a light module for a motor vehicle headlight with the features of the preamble of claim 1. Furthermore, the invention relates to a pig headlight with such a light module according to the preamble of claim 11.
  • LED light sources comprising one or more LED chips
  • Such LED light modules usually comprise at least one bundling optical unit in the form of a front lens made of a solid transparent material, in particular plastic or glass.
  • the light emitted by the semiconductor light source or sources is coupled via one or more light entry surfaces in the optical attachment, is at least partially deflected by means of total reflection at interfaces of the optical attachment and finally coupled via one or more light exit surfaces of the attachment optics.
  • the bundling of the light takes place by refraction at the light entrance and / or light exit as well as by the deflection by total reflection.
  • a light source of LED light modules a plurality of matrix-like juxtaposed and / or stacked LED chips can be used, which can be controlled separately or in groups separately. In this way, a plurality of partial light bundles can be generated, which complement or overlap the resulting light bundle of the light module for generating the predetermined light distribution.
  • selected areas of the light distribution for example in the area of oncoming or preceding vehicles, can be selectively masked out. In this case, a better illumination of the area in front of the motor vehicle can be achieved, since it is more often possible to drive with high beam, whereby dazzling of other road users is prevented since areas in which they are located are deliberately masked out.
  • Such light modules are referred to as multi-beam LED modules or as matrix LED modules.
  • multi-beam LED modules include semiconductor light sources, each having 84 matrix-like LED chips.
  • the light distribution of the light module is thus composed of 84 areas that can be hidden or illuminated individually or in groups.
  • Such a light distribution is also referred to as adaptive driving beam (ADB), glare-free high beam or partial high beam.
  • ADB adaptive driving beam
  • a light pixel corresponds to the light distribution at a distance of 100 m in front of the motor vehicle of an area of 1.8 ⁇ 2.4 m.
  • the motor vehicle has suitable sensors, eg. In the form of a camera, and suitable processing logic that determines the position of the other road users from the sensor signals and generates suitable drive signals for the light modules or their LED chips.
  • a matrix LED module is the basic structure ago, for example, from the DE 100 09 782 A1 known. It shows how such a matrix LED module can be used in combination with a projection lens to generate a variable light distribution. If a matrix LED module is integrated into a headlight of a motor vehicle, the light distribution can be adapted dynamically to the traffic conditions (eg oncoming or preceding vehicle) with the aim of optimal light distribution for the driver of the motor vehicle and at the same time dazzling other road users to avoid.
  • traffic conditions eg oncoming or preceding vehicle
  • LED modules include so-called pAFS (micro-structured adaptive front-lighting system) light modules, in which a matrix with currently up to 1,024 individually controllable LEDs is used.
  • pAFS micro-structured adaptive front-lighting system
  • a multiplicity of white LEDs eg blue LEDs with integrated converter
  • pixels eg per LED one pixel.
  • Each LED emits light with a lambertian radiation distribution in the half space perpendicular to the light exit surface of the LED.
  • a projection optic forms the light surface as a light distribution on the road ahead of Motor vehicle off.
  • the resulting light distribution of a single light module thus includes, for example, 4,096 subareas (so-called light pixels) which can be blanked out individually or in groups.
  • the light distribution is thus divided into 8,192 light pixels. This finer subdivision of the light distribution makes it possible to bring the illuminated areas of the light distribution closer to the position where other road users were detected, and thus to achieve improved illumination in front of the motor vehicle, but without dazzling other road users.
  • DLP digital light processing
  • the light from an LED eg high current LED
  • a micromirror array which includes a plurality (for example, more than 1 million) tiny micromirrors , which can be individually controlled and tilted with a frequency of up to 5,000 Hz.
  • a concave mirror can be used for deflecting the light emitted by the LED.
  • a pixel of the light distribution corresponds to a surface of only 4.0 x 2.5 cm at a distance of 100 m in front of the motor vehicle. The state of the individual mirrors determines the path of the light.
  • one of the micromirrors If one of the micromirrors is in its initial position, it reflects the light incident on it completely via projection optics, which are designed, for example, as a projection lens, onto the road ahead of the motor vehicle.
  • projection optics which are designed, for example, as a projection lens
  • the reflected light no longer lands on the road, but, for example, in a light trap, so that the corresponding light pixel is deactivated and there is an unlit spot in the light distribution.
  • gray levels (with lower brightness) can be generated at the respective light pixels.
  • Headlamps with a DLP module are also referred to as HD (high definition) headlights.
  • the light distribution must be generated as accurately as possible in front of the motor vehicle. This applies in particular when the light modules produce a dimmed light distribution with a light-dark boundary between the illuminated near area of the light distribution and the non-illuminated far area or a partial high beam with horizontal and vertical light-dark boundaries between the illuminated areas (light pixels) of the light distribution and the non-illuminated areas should.
  • the finer the subdivision of the light distribution into light pixels the more important is a highly accurate positioning of the light distribution or of the individual light pixels in front of the motor vehicle in order to prevent dazzling of other road users.
  • projection optics can focus only light with an upward limited opening angle (eg maximum +/- 20 °), it is advantageous to limit the emission range of the light emission unit.
  • Light that falls on the projection optics at too great an angle is poorly or blurred due to optical aberrations, which generally increase with the angle of incidence oblique to the optical axis.
  • light that can enter at large angles of incidence Projection optics fall, lead to stray light, which further reduces the contrast of the image.
  • the accuracies of the light distribution required with pAFS modules and DLP modules can not be achieved.
  • the present invention has the object to provide a compact, optical projection system for matrix LEDs available, which prevents light incident at too large angles of incidence in the projection optics.
  • a light module is proposed with the features of claim 1.
  • a light module for a headlamp of a motor vehicle wherein the light module has a light emission unit with a plurality of point-like light sources arranged in a matrix, each emitting light with a Lambertian radiation characteristic, and projection optics having at least one projection lens which illuminate the light emitted by the light emission unit as the resulting light distribution of the light module on a roadway in front of the motor vehicle.
  • the light module comprises in a beam path between the light emission unit and the projection optics a lens which has a concave curved exit surface on the side remote from the light emission unit. The exit surface deflects light emitted by the light emission unit with a large emission angle and impinging on the tread surface of the lens by means of total reflection toward the edge, so that it no longer passes through the projection optics.
  • a lens in a main radiation direction of the light emission unit arranged in front of this, so that the light emitted by the light emission unit light hits the lens.
  • the lens has an entrance side directed toward the light emission unit and an outlet side facing away from the light emission unit.
  • the exit side has a concave curvature. This causes the light emitted by the light emission unit at large angles (eg> 30 °) relative to the optical axis and incident on the exit surface to be totally reflected and dissipated laterally. This prevents it from reaching the projection optics and being imaged by them.
  • the imaging properties of the projection system can be improved, in particular the contrast and the sharpness of the image can be increased.
  • a lens for filtering out light emitted by the light emitting unit at a large angle of radiation from the beam used to generate the light distribution has over the use of a diaphragm, such as WO 2013/020 156 A1 is known, significant benefits.
  • the effective area or edge of a panel always has a fixed position with respect to the light-emitting unit.
  • the lens used according to the invention due to the curvature of the totally reflecting exit surface, there is a shift in the surface areas of the exit surface which are effectively used for the total reflection, depending on which position in the light emission unit the respective punctiform light source is arranged.
  • Area sections used for punctiform light sources arranged at the outer edge of the light emission unit are located higher on the exit surface (and thus have a greater curvature) than the area of the exit surface (with less curvature) used for punctiform light sources located at the center of the light emitting unit. This would be something like an aperture for the light rays of punctiform light sources arranged at the outer edge of the light emitting unit, which is located slightly further outside than a diaphragm for the light rays of punctiform light sources arranged in the center of the light emission unit.
  • the use of a lens increases the efficiency of the light module over the use of a diaphragm, since less light is lost (filtered out) when using a lens with the point-shaped light sources arranged at the outer edge of the light source , is deflected towards the edge) than when using a shutter.
  • the light reflected toward the edge strike an outer edge of the optical system which has light-absorbing properties.
  • scattered light which could be caused by the light deflected from the exit surface to the edge, can be prevented, since the deflected light can no longer pass uncontrolled back to the projection optics and on into the resulting light distribution.
  • a light-absorbing layer is applied to the outer edge of the optic.
  • the point-like light sources arranged in the form of a matrix are used as semiconductor light sources, in particular as light-emitting diodes (LEDs) or semiconductor lasers are formed.
  • LEDs light-emitting diodes

  • projection optics can focus only on light with an opening angle limited to approx. +/- 20 °. Light beams with opening angles greater than +/- 20 °, in particular greater than +/- 30 °, are thus prevented from hitting the projection optics.
  • the entrance surface of the lens facing the light emitting unit may be arbitrarily (e.g., curved).
  • the light emission unit facing the entrance surface of the lens is preferably formed flat. It is also conceivable for an antireflection coating to be applied to the entrance surface of the lens facing the light source in order to prevent backscattering of the light emission unit.
