Abstract
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.
