Definitions

  • the invention relates to a laser illumination device for vehicles with two or more laser light sources, each adapted to produce a primary laser light beam, each assigned to each laser light source light guide, each primary laser light beam coupled to its first end and decoupled from its second end as a secondary laser light beam and each secondary Laser light beam is directed to a light conversion means to generate a predetermined luminous image on this, which is projected via a the light conversion means associated with the projection system as a light image on the road.
  • the invention relates to a headlight with at least one such laser illumination device.
  • the invention relates to a vehicle with at least one such headlight.
  • Headlamps that work with laser beams scanning via a light conversion medium are known. They usually generate a light image on a light conversion medium, often called “phosphor” for short, on which the blue laser light, for example, is converted into essentially "white” light by fluorescence. The luminous image produced is then projected onto the roadway with the aid of the imaging system, for example a lens optic (see, for example, US Pat US 20150062943 A1 . JP 2013232390 A . US 20120051074 A1 . JP 2014010918 A . WO 2014121314 A1 and US 20130265561 A1 ).
  • the microscanner is generally a beam deflection means, for example a micromirror, which can be moved about one or two axes, so that, for example, a row-by-row illumination image is "written".
  • the modulation of the laser light source determines the desired luminance for each point or line of the luminous image, which on the one hand has to comply with legal specifications for the projected photograph and, on the other hand, can be adapted to the respective driving situation.
  • micro-scanner with one or more laser beams, which are modulated synchronously with the mirror oscillation, makes it possible to produce almost any light distribution.
  • Such a method is also known in principle so-called Pico projectors and head-up displays, which also use micromirrors, which are designed as MEMS (micro-electro-mechanical systems).
  • MEMS micro-electro-mechanical systems
  • significantly higher laser powers must be introduced for headlamps.
  • working with blue laser light which originates for example from laser diodes, is usually used. In view of the required high laser power in the order of 5 to 30 watts, it is important to make the best possible use of the laser power installed in a headlight.
  • the so-called 1D microscanner systems find their application in the headlamps.
  • Several blue laser diodes are arranged so that the laser beams generated by them are directed to the phosphor via a single 1D microscanner.
  • a "1D microscanner” is understood to mean a microscanner movable about a single axis. Each laser diode illuminates its own area on the phosphor so that separate lines are "written".
  • the spot diameter of the laser diodes i. the diameter of a light spot generated by the corresponding laser diode by the fluorescence, be correspondingly different on the phosphor.
  • these values can vary widely, e.g. if line heights between 0.2 mm and 0.9 mm are to be realized on a phosphor.
  • the light intensity in such a spot usually has a Gaussian shape, and decreases exponentially to spots edges (see, eg US 20150062943 A1 and US 20130265561 A1 ).
  • the laser beams generated by the conventional laser diodes have spatial asymmetries, which is why the spot is substantially elliptical, wherein the length of the ellipse main axis may differ greatly from the length of the ellipse axis.
  • the limit of the spot is usually assumed to be the point at which the intensity has fallen to 1 / e or to 1 / e 2 . The assumed value then defines the boundary to the next line in the luminous image.
  • An object of the invention is to provide a laser illumination device in which a light image with improved photometric properties can be realized. This object is achieved with a laser illumination device of the aforementioned type according to the invention that each primary laser light beam couples into a first end of the optical fiber and decouples from a second optical fiber end as a secondary laser light beam, wherein the second ends are arranged adjacent to each other in a row, and the light guide a different have a large cross-section.
  • the micro-scanner In an embodiment which is expedient with regard to the control-related expenditure, provision can be made for the micro-scanner to be pivotable about exactly one axis.
  • Such a 1D microscanner can also be used to deal with EMC problems (EMC stands for electromagnetic compatibility).
  • EMC electromagnetic compatibility
  • the beam deflection means such as a micromirror
  • the beam deflection means must oscillate a lot faster, so that a uniformly illuminated light image can be realized as the path through which the image is scanned will be much longer. As a result, one must be able to turn on and off the laser light sources themselves very quickly.
  • each laser light source is followed by an optical attachment which couples the primary laser light beam into the first end of the optical waveguide associated with this laser light source.

  • modulating in the context of the present invention is meant that the intensity of a laser light source can be changed, be it continuous or pulsed, in the sense of switching on and off, pulsed. It is essential that the light output can be changed dynamically analogously, depending on where the beams are directed. In addition, there is the possibility of switching on and off for a certain time in order not to illuminate defined places
  • the laser driver 3 in turn contains signals from a central headlight driver 4, which sensor signals s1 ... si ... sn can be supplied.
  • these control and sensor signals can be, for example, switching commands for switching from high beam to low beam or, on the other hand, signals received by light sensors or cameras which detect the lighting conditions on the road and, for example, hide or attenuate certain areas in the light screen.
  • Each laser light source 11 to 18 is followed by its own collimator optics 21 to 28, which bundles the initially highly divergent laser beam 11p to 18p.
