Abstract:
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.
