A headlamp () for vehicles having at least one laser light module () which has a laser light source () and a phosphorus element () which is arranged downstream of the latter in the beam path and a front-end optical system () in which the at least one laser light module is arranged in a housing () of the headlamp which has a projection optical system () for projecting the light distribution generated in the focal plane of the projection optical system of the at least one laser light module into the carriageway space, and at least one deflection prism () is integrated into the at least one front-end optical system (), which deflection prism () lies in the region of the laser beam (--) which occurs when the phosphorus element () is defective or missing and which deflects this laser beam occurring in the event of disruption and keeps it away from the projection optical system and therefore from the carriageway space.

Headlamp for vehicles having at least one laser light module

The invention relates to an illumination apparatus (), in particular for a motor vehicle, comprising at least one laser light source () for producing excitation light, at least one wavelength conversion element (), which is designed to receive excitation light from the at least one laser light source () in the form of an excitation-light light bundle, at least one optical imaging element (), which images light, which is emitted in the visible wavelength range by the wavelength conversion element (), in the form of at least one light distribution or one partial light distribution (LVa, LVb, LVc, LVd, LVe), and at least one beam-deflecting device in the beam path between the at least one laser light source () and the at least one wavelength conversion element (). The beam-deflecting device is designed as an acousto-optic modulator (), which comprises a solid medium (), which is optically transparent at least to excitation light of the at least one laser light source () and through which the excitation-light light bundle is passed, and wherein a control device () is provided, by means of which sound waves having a frequency or a plurality of, in particular, different frequencies can be produced in the solid medium () of the acousto-optic modulator () in accordance with specified or specifiable control parameters such that the excitation-light light bundle is deflected to different regions () of a conversion element () and/or to different conversion elements in accordance with the frequency of the applied sound waves.

Illumination apparatus for a motor vehicle

A headlight for vehicles, said headlight comprising at least one light source () together with a focusing optical unit (), a micromirror array (), and an imaging optical unit (), wherein a central computing unit () comprising a light source control () and an array control () is associated with the light source and with the micromirror array, and the central computing unit is configured to switch the position of the micromirrors between an OFF state and an ON state periodically with a predefined control frequency and a predefined duty cycle by means of the array control, and the formed light ray () from the at least one light source is directed at the micromirror array, and the light beam structured and reflected thereby is projected onto the road () as a light pattern () via the imaging optical unit (), wherein the computing unit () is configured to suppress the focused light ray () directed at the micromirror array () at predefinable times and synchronously with the control frequency of the micromirror array by means of the light source control () and/or the array control ().
