Light beam projection device with mechanical actuator, optical module and headlamp provided with such a device
A device for projecting a light beam and having a mechanical actuator, notably for a motor vehicle, including an array of light sources able to emit light rays in order to form the light beam along an optical axis, each light source defining a component of the light beam which has an angle of resolution defined in a plane, the device including moreover a mechanical actuator configured for displacing at least one element of the device in such a way that the optical axis of the light beam is moved between at least two projection directions at a specified frequency of displacement, the projection directions forming between them an angle of displacement substantially coplanar with the angle of resolution, the angle of displacement being equal to a fraction of the angle of resolution of the beam.
Light control systems and methods
Provided is a beam-steering mechanism, comprising a lens and a light source positioned in a focal plane of the lens. One of the light source and the lens moves relative to the other of the light source and the lens. The light source outputs a light beam at the lens which forms an illumination spot on a surface from the light beam. The illumination spot moves in a direction in response to a movement of one of the light source and the lens.
LIGHTING TOOL FOR VEHICLE
A lighting tool for a vehicle includes a first condensing optical system configured to condense a first beam at a first condensing magnification, a second condensing optical system configured to condense a second beam at a second condensing magnification, and a projection optical system configured to project the first beam and the second beam forward, wherein each of a condensing point of the first beam condensed by the first condensing optical system and a condensing point of the second beam condensed by the second condensing optical system are adjusted according to a rear-side focus of the projection optical system.
VEHICLE LAMP
A vehicle lamp includes a projection lens, and a light source disposed behind the projection lens. The vehicle lamp is configured to form a required light distribution pattern by irradiating light emitted from the light source forward through the projection lens. A movable lens configured to be movable in a required direction intersecting with an optical axis of the projection lens is disposed between the projection lens and the light source. A maximum luminous intensity position of the light distribution pattern is changed by moving the movable lens in the required direction.
Light device with movable scanning means and optical fiber
A light device, notably for a motor vehicle including at least one laser light source emitting a laser light beam, a wavelength conversion material capable of converting one part of a laser light beam, diffusing another part of the laser light beam and combining the diffused and converted parts into a resultant primary light beam, a movable scanning means for scanning the laser light beam onto the wavelength conversion material, an optical means of projection of the primary light beam, an optical fiber arranged for receiving on an input face the laser light beam emitted by the laser light source and for directing the laser light beam toward the movable scanning means.
Light module, motor vehicle light assembly, and production method
A light module for a motor vehicle light is obtained, comprising a light source assembly comprising at least one light source unit, at least one first guide section, and at least one first fasting section, and an optics assembly comprising at least one optical element, at least one second guide section, and at least one second fastening section, wherein the light source assembly and the optics assembly can be moved toward one another along the adjustment axis (J) in a first state, in particular an adjustment state, by the first guide sections, and wherein the light source assembly and the optics assembly can be fixed in place in relation to one another with the first and second fastening sections in a second state, in particular in an adjusted final assembly state.
Gear shift adjusting mechanism and headlight device
A gear shift adjusting mechanism includes: an adjustment unit including a first slider; an adjustment target module including a second slider; and a switch unit including a first rotation shaft and a link member supported rotatably with respect to a fixing member about the first rotation shaft. The link member includes a first engaged part that is engaged with a first engaging part of the first slider and a second engaged part that is engaged with a second engaging part of the second slider. The switch unit moves at least one of the first rotation shaft, the first engaging part, or the second engaging part so that at least one of a first distance between the first rotation shaft and the first engaging part or a second distance between the first rotation shaft and the second engaging part is changed.
Light irradiation device having two wedge prisms and an aberration correction surface
A light irradiation device includes a light source, a projection optical system, wedge prisms, and an aberration correction surface. The projection optical system projects an image formed based on light emitted from the light source. The aberration correction surface corrects an aberration occurring when the image is projected by the projection optical system. The wedge prism deflects the light emitted from the projection optical system. The wedge prism deflects the light deflected by the wedge prism. The wedge prisms are held so that a deflection direction of light emitted from the wedge prism is changed by rotation of at least one of the wedge prisms. The aberration correction surface is on the wedge prism side with respect to an emission surface of the projection optical system, and is located on the projection optical system side, with respect to the wedge prism, including an incidence surface of the wedge prism.
Device and method for controlling a headlight
A device and a method for controlling at least one headlight for a motor vehicle involve a control apparatus, at least one sensor configured to detect information about objects in a surrounding area of the motor vehicle and to supply the detected information to the control apparatus. The headlight can be adjusted by the control apparatus depending on at least one detected object. A range between at least one light source and at least one lens of the headlight can be adjusted by the control apparatus in order to adapt a projection of the light source to the at least one detected object.
Lamp for vehicle
The present disclosure relates to a lamp for a vehicle, and more particularly, to a lamp for a vehicle which is capable of preventing occurrence of a blind zone caused by a defect. The lamp includes a light source portion with a plurality of light emitting areas in which brightness of generated light is separately controllable and a brightness controller which is configured to cause the plurality of light emitting areas to generate light at a first brightness level to form a beam pattern and to cause at least one of the light emitting areas, which is disposed proximate to a defective area which includes at least one faulty area, to generate light at a second brightness level.
