Patent number: 10480740Abstract: 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.Type: GrantFiled: January 23, 2018Date of Patent: November 19, 2019Assignee: VARROC LIGHTING SYSTEMS, S.R.O.Inventors: Jan Kratochvil, Michaela Duliakova, Vladimir Kubena, Zdenek Mikeska, Kvetoslav Odstrcilik, Radek Orlita

Patent number: 10359166Abstract: A light device, especially a headlight for motor vehicles, comprises a holding bushing (1), covered by a translucent cover (2), and an inner chamber (3) having mounted there in an optical system (5) for generation of light rays and enabling of controlled selective changes of a light trace on a projection surface. The optical system includes a lens (51) and a light assembly (52) comprising at least one light source and a carrier to carry the light source. The lens is arranged in a fixed position with respect to the position of the translucent cover, and the position of the light assembly is selectively adjustable in a controlled way with respect to the position of the lens by movement of the light assembly in direction (A) and/or by movement in direction (B), wherein the directions (A) and (B) are substantially perpendicular to direction of optical axis (C) of the lens.Type: GrantFiled: July 26, 2016Date of Patent: July 23, 2019Assignee: Varroc Lighting Systems, S.R.O.Inventors: Jan Kratochvil, Ondrej Hasa, Jan Grof, Milos Macicek, Radek Orlita

Patent number: 10337686Abstract: A headlight for a vehicle with a projector includes a reflector, a light source, a diaphragm, and a collimating optical element. The reflector includes a bowl-shaped reflective surface, which presents the shape of a concave curve in a cross-section formed by a vertical plane passing through the optical axis of the projector. The light source is positioned substantially at the source focal point of the curve. The diaphragm is positioned substantially at the image focal point of the curve to create a light-darkness boundary in front of the vehicle. The optical element is for collimation of the output light beam into the required direction. The diaphragm is made of a transparent material and includes one or more optical surfaces arranged to direct those rays that have fallen onto it and passed through it to the collimating element directly, or through a supplementary optical element.Type: GrantFiled: October 19, 2017Date of Patent: July 2, 2019Assignee: VARROC LIGHTING SYSTEMS, S.R.O.Inventors: Jan Kratochvil, Dana Pekarkova, Radek Orlita

Patent number: 9995452Abstract: A light device, especially a headlight of motor vehicles, comprises at least one light unit (1), or a group (1a, 1b) of light units, at least one optical directing element (3, 2e, 3f), adapted to direct the light beam emitted by the light unit, or group of light units, to the required direction, and at least one output lens (4) for passage of at least a part of the light rays of the light beam or beams to create a light pattern (A, B, C) on the display surface (ZY). On the route of the light beam between the optical directing element and the output lens, there is at least one optical diaphragm element (11, 21, 31) containing a system of trim edges (13, 23, 33) to create the required shape of the cross-section of a part or parts of the light beam designed for transmission along the above-mentioned route.Type: GrantFiled: February 11, 2016Date of Patent: June 12, 2018Assignee: Varroc Lighting Systems, s.r.o.Inventors: Jan Kratochvil, Dana Pekarkova, Ondrej Hasa, Jan Grof, Milos Macicek, Zdenek Mikeska, Milan Kytka, Radek Orlita, Tomas David, David Hynar
