A vehicle lighting device that includes a laser radiation source, wherein a controlled reflective MEMS scanning mirror is situated in the path of laser radiation from the laser radiation source, wherein in the path of radiation reflected by the controlled reflective MEMS scanning mirror is located an imaging optical element and further an output optics, wherein the laser radiation source and the MEMS are connected to a power supply and control device. The laser radiation source is formed by an RGB laser radiation source with output white light and the imaging optical element is formed by a screen which is adapted to convert a narrow beam of laser white light directed at the screen surface from the RGB laser source by means of the controlled MEMS reflective scanning mirror at each point of the screen surface to a point source of uniform white light on the screen surface, wherein the uniform white light from this point source on the screen surface has a spherical wavefront of white light propagation and has the same wavelength as the white light directed by the controlled MEMS reflective scanning mirror onto the screen, whereby the output optics is arranged in the direction of travel of the white light with the spherical wavefront from the point source on the screen surface.

Vehicle lighting device with a laser radiation source

A communication device is provided for a motor vehicle that works with traffic-relevant information provided through light signals. The communication device comprises a primary imaging optical system to create the input image from the received scenic image, which may comprise a light car2car signal and/or a light car2X signal including traffic-relevant information. It further comprises a DMD array of mirrors for receiving the input image and transmitting it to a primary optical sensor adapted to convert the input optical image to an electric signal for processing, to thereby find out whether and what places of the input image sources of the signals are found in.

Communication device of a motor vehicle

A light device comprises a laser light source, a primary optical system with at least one diffractive and/or at least one reflective optical element to convert monochromatic coherent light to a collimated beam of coherent light, a MOEMS comprising one or more micro-mirrors to route coherent light and convert it to white light, and a secondary optical system comprising at least one diffractive and/or at least one reflective optical element to direct white light from the light device to create a light pattern on the display surface and/or in specific zones in front of the vehicle. It further comprises an electromagnetic control system connected to the MOEMS and the light source to control changes of rotation angle, oscillation angle and oscillation rate and frequency of one of the micro-mirrors, and to control the light source activity, for controlled changing of the shape and/or position of the light pattern depending on current conditions of the vehicle.
