Definitions

  • the present invention relates to a laser headlight according to the preamble of claim 1.
  • Such a laser headlight has, among other things, a laser light source, a phosphor and a light deflection device which is set up to illuminate different partial areas of the phosphor with laser light at different times, the light deflection device having at least one movable first light deflection element which is set up for this purpose directing incident laser light in different spatial directions at different points in time, and wherein the light deflection device is set up to direct light directed in a first spatial direction in a first beam path onto a first partial area of the phosphor, and light directed in a second spatial direction in a second beam path on a second
  • Such a light deflection element is also referred to below as a scanner.
  • a scanner for example, headlights can be built that can produce almost any light distribution. This enables dynamic adjustment of a light distribution generated by the headlight to changing traffic conditions.
  • a camera installed in the motor vehicle records the traffic situation in front of the vehicle.
  • Software analyzes the images and controls the light deflection element and thus the light distribution in such a way that the road is always optimally illuminated and oncoming traffic is prevented from being dazzled. This increases safety in particular when driving at night.
  • a headlight equipped with a scanner is from the DE 10 2007 055 480 B3 famous.
  • a focused laser beam from a laser that emits blue light is moved using a scanner over a phosphor (eg a phosphor), which converts the blue light from the laser into white mixed light by mixing it with yellow or yellow-red fluorescent light.
  • the white light is directed onto the road via an optic. Any light distribution can be generated by moving the light spot of the focused laser beam on the illuminant and simultaneously modulating the laser power.
  • a headlight which has an angularly movable reflector which very quickly deflects a narrow beam in different directions in space.
  • small areas are sequentially illuminated in time with changes in direction of the beam and thus scanned with light and thus scanned.
  • a sufficiently fast scanning results for example when the sampling sequence is repeated at a frequency greater than 100 Hz.
  • a laser headlight having the features of the preamble of
  • Claim 1 is from the U.S. 2013/258689 A1 famous.
  • the light color of the light emanating from the phosphor in different directions changes depending on the direction. For example, the light from the headlight tends to appear slightly whiter in one direction than in a second direction and slightly yellower in the second direction than in the first direction. This is an unwanted effect.
  • the object of the invention is to specify a laser headlight of the type mentioned at the outset in which this undesired effect does not occur or at least only occurs to a greatly reduced extent.
  • the laser headlight according to the invention differs from the known laser headlight by the characterizing features of claim 1.
  • the headlight according to the invention thus has the features of the preamble of claim 1 mentioned at the outset and is further characterized in that the first The direction of incidence is parallel to the second direction of incidence.
  • the term spatial direction refers here to the emitted light
  • incidence direction refers to the incident light.
  • the direction of incidence refers to the perpendicular of the illuminated surface at the point of incidence of the light beam.
  • the laser headlight according to the invention is set up to let the light directed onto the first partial area impinge there from a first direction of incidence and to let the light directed onto the second partial area impinge there from a second direction of incidence, with an angle between the first direction of incidence and the second direction of incidence is smaller than the angle between the first spatial direction and the second spatial direction, the difference in the directions of incidence during a movement of the movable first light deflection element changes less in the invention than the spatial directions of the light emanating from the movable first light deflection element.
  • the invention is based on the finding that the directional dependence of the light color also depends on the preferred direction in which the laser light scattered in the phosphor (primary light) exits the phosphor and that this preferred direction depends on the direction of incidence on the phosphor and thus on the point of impact on the phosphor, while that emanating from the phosphor Fluorescent light has an emission characteristic that is independent of this point of incidence.
  • the undesired color variation thus depends on the angle variation of the laser light incident on the phosphor. The greater this angle variation, the greater the undesirable color variation.
  • the angular variation is in any case smaller than the angular variation of the spatial directions in which the laser light emanates from the first movable light deflection element. As a result, the desired reduction in color variation also occurs with the invention.
  • the invention can be implemented as a constructive addition to existing systems, which reduces development costs and facilitates adjustments to headlight designs that may differ from vehicle type to vehicle type.
  • the invention realizes the ideal case in which the undesired directional dependency of the light color disappears.
  • a preferred embodiment is characterized in that the light deflection device has a second light deflection element, which is located in the beam path between the movable first light deflection element and the phosphor.
  • the light deflection device has collimating optics, in particular a converging lens, arranged between the movable light deflection element and the phosphor.
  • the converging lens is a convex-plane lens, which faces the phosphor with its plane side.
  • a preferred embodiment is characterized in that the converging lens is arranged in the beam path directly in front of the phosphor.
  • the phosphor is arranged adhering to the planar side of the lens.
  • the phosphor has a curved shape, so that the sum of the partial regions results in a curved surface.
  • This configuration has the particular advantage that it only requires a special form of the phosphor, but no additional parts such as lenses or mirrors as the second light deflection element.
  • the surface is preferably curved in such a way that the direction of incidence relative to the perpendicular of a surface element of the point of impingement of a light beam is independent of the point of impingement.
  • a preferred embodiment is characterized in that the second light deflection element has a curved mirror surface.
  • the second light deflection element is a movable light deflection element that can be moved at the same time as the first movable deflection element.
  • the second light deflection element is a Fresnel lens or a flat diffractive structure.
  • Fig.1 shows the schematic structure of a laser light module of a known laser headlight with scanner.
  • the light 7 from a blue laser 1 is focused onto a phosphor 5 using a lens 2 and a scanner 3 .
  • the scanner is, for example, a mirror that can be moved quickly in a controlled manner.
  • a blue laser is a laser that emits blue light from the visible spectral range.
  • the phosphor implemented for example as a phosphor layer, scatters the blue light and converts part of it into yellow light.
  • the blue and yellow light components together result in white mixed light 11.
  • the scanner makes it possible to direct the laser beam onto different areas 5a, 5b of the phosphor. In different areas, the laser beam strikes from different directions, i.e. at different angles to the perpendicular at the point of impact. The change in the angle of incidence from area to area becomes particularly large when the distance between the scanner and the phosphor is small. However, small distances are necessary in order to keep the size of the headlight small.
  • the mixed light 4 generated in the phosphor 5 is directed via a projection lens 6 into the area in front of the headlight, where it is used to illuminate the roadway when the headlight is used as intended in a motor vehicle.
  • the Figures 2 and 3 illustrate a change in the emission characteristics of laser light scattered in the phosphor when the direction of incidence of the laser light changes.
  • the figure 2 a situation with perpendicular incidence of light
  • the figure 3 shows a situation with oblique incidence of light.
  • the blue laser light 7 falls perpendicularly onto the phosphor 5.
  • a portion 9 of the blue laser light 7 is scattered, preferably in the forward direction, i.e. in the imaginary extension of the direction of incidence of the laser light 7 on the phosphor 5.
  • This blue color component 9 has a maximum intensity in direction of the incident laser beam 7.
  • Another portion of the blue laser light is absorbed by the illuminant and emitted as fluorescent light 8 in the yellow spectral range with a specific emission characteristic. In the case shown, this is a Lambertian emission characteristic.
  • the laser beam 7 falls obliquely on the Bulb 5 on. Again, some of the blue laser light is scattered preferentially in the forward direction and thus towards the obliquely incident laser beam. Due to the longer distance in the illuminant, however, the effective scattering is stronger than with vertical incidence. As a result, the scattering in the preferred forward direction is less pronounced than with normal incidence.
  • the laser light is again absorbed by the phosphor and emitted as fluorescent light 8 in the yellow or yellow-red spectral range.
  • the emission characteristic of the fluorescent light 8 does not depend on the direction of incidence of the laser light.
  • the invention ideally achieves the situation where the laser beam impinges on the phosphor from the same direction of incidence in the entire scanning area.
  • the scattered laser light then has the same emission characteristics in each sub-area of the phosphor. This ensures that the light color does not change in the entire scan area.
  • the figure 4 shows a first exemplary embodiment of a laser headlight 10 according to the invention.
  • the headlight 10 has a housing 12 with a light exit opening which is covered by a transparent cover plate 14 is.
  • a laser light module 16 is located inside the headlight 10.
  • the laser light module has in particular a laser light source 18 which emits laser light 17 from a first wavelength range.
  • the first wavelength range preferably comprises a narrow range from the blue part of the spectrum of visible light.
  • the light emitted by the laser is focused with the first focusing optics 20 and directed onto the converging lens 24 by the movable first light deflection element 22 .
  • the movable first light deflection element is moved by an actuator 19 in an oscillating manner about a pivot point 21 .
  • the actuator 19 is a piezo actuator or a micromirror, for example.
  • Actuator 19 is controlled by a control unit 23, which for this purpose receives signals from a central light control unit of a motor vehicle, which processes signals from vehicle sensors such as a front-end camera, an ambient brightness sensor, a driver's request transmitter, etc. to form a control signal for actuator 19, without these Listing is meant to be final.
  • the converging lens 24 forms, together with the first movable light deflecting element, an embodiment of a light deflecting device in the sense of claim 1.
  • the converging lens 24 is arranged between the movable light deflecting element 22 and the phosphor 26 .
  • the phosphor which is implemented as a phosphor layer, for example, scatters the blue light and converts part of it into yellow or yellow-red fluorescent light.
  • the blue and yellow light components together result in the white mixed light.
  • the invention is not limited to this special conversion and mixing.
  • laser light of a shorter wavelength in the phosphor becomes partly in fluorescent light of a longer one wavelength converted.
  • the fluorescent light mixes with scattered but unconverted laser light to form a mixed light.
  • the converging lens (24) aligns the incident laser light (17) in parallel and lets it impinge on the phosphor 26 lying in the light path behind the converging lens.
  • the focusing effected by the first focusing optics 20, in conjunction with the already small diameter and opening angle of the laser beam 17, causes only a partial area 26a, 26b of the light entry surface of the phosphor 26 to be illuminated at any time. In the figure 1 this is just an upper portion 26a of the phosphor.
  • White mixed light 28 therefore emanates from this partial area, which is directed by the projection optics 30 into the area in front of the light module 16 and thus of the headlight 10 .
  • the projection optics 30 is illuminated with white mixed light 28 from a different direction from each partial area.
  • the projection optics 30 then also generates a corresponding bright spot in front of the headlight 10 at different points in the front area.
  • a light distribution is generated in this way as the sum of the bright light spots generated by the projection optics 30 .
  • the movement takes place particularly quickly when the sequence of the different positions of the movable first light deflection element is repeated at a frequency of more than 100 Hz, because the human sense of sight then only perceives an average brightness of the light distribution generated overall.
