Embodiment Construction

[0035] now refer to figure 1 Embodiments of the present invention are further described. In particular, the important parts for the headlight according to the invention are shown, wherein it is obvious that the motor vehicle headlight also contains many other parts, which enable the headlight to be used meaningfully in motor vehicles (for example, in particular passenger cars or motorcycles). The optical starting point of the headlights is the two groups 1 and 2 overlapping here with three laser light sources 11 , 12 , 13 or 14 , 15 , 16 , each of which can emit a signal denoted by 11s to 16s laser rays. A laser control system 3 is associated with the laser light sources 11 to 16 , wherein the control system 3 is used for power supply and is also designed to adjust the beam intensity of the individual lasers. In the context of the present invention, "modulation" is understood to mean that the intensity of the laser light source can be varied, which shall be continuous or pu...

Abstract

The invention relates to a headlight for motor vehicles comprising at least one modular laser light source (11 - 16), the laser beam thereof being directed, via beam deflection means (51, 52) which are controlled by a deflection control (9), to light conversion means (60), also comprising a projection system (70) for projecting the light image generated on the light conversion means to the road. A first group (1) of at least two laser light sources (11, 12, 13) for generating a first group of at least two superimposed, essentially horizontal light bands (61, 62, 63) on the light conversion means (60) and a second group (2) of at least two laser light sources (14, 15, 16) for generating a second group of at least two superimposed, essentially horizontal light bands (64, 65, 66) on the light conversion means (60) are provided. A laser control (3) is associated with the laser light sources (11 - 16), and the laser beams (11s - 16s) are directed by the laser deflection means (51, 52) to the light conversion means (60) such that light bands (61, 62, 63) of the first group (1) and light bands (64, 65, 66) of the second group overlap each other.

Description

technical field [0001] The invention relates to a method for generating a predetermined light distribution on a roadway by means of a motor vehicle headlight, in which at least one conditioned laser beam is deflected by at least one beam deflection device onto a light conversion device and converts the light into The lighting image (Leuchtbild) generated at the device is projected onto the roadway. [0002] The invention likewise relates to a headlight for a motor vehicle, which has: at least one adjustable laser light source, the laser beam of which is deflected via a beam deflection device actuated by a beam deflection control device onto at least one light conversion device; and A projection system for projecting the illuminated image produced on the luminescent material layer onto the roadway. Background technique [0003] The use of laser light sources in motor vehicles is now of great importance, because laser diodes enable flexible and efficient solutions, which also...
