The light device comprises an internal chamber () that is covered by a translucent cover, which separates the light device from the external surroundings of the motor vehicle; inside the chamber, there is at least one lighting unit () whose active area () for the exit of light rays () from the lighting unit () is situated opposite the translucent cover and contains a light-conductive core () of an optically transparent material with an associated light unit () located opposite the entry area () of the light-conductive core () to emit light rays () into the body () of light-conductive core (). Between the light-conductive core () and the translucent cover there is a functional layer () configured to focus the beams of light rays () that exit its surface averted from the light-conductive core () in a predetermined direction. The light device comprises a technological layer () that is configured for a total reflection of the light rays (), which is in contact with the top surface () of the light-conductive core ().

Light 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.
