摘要:
The present invention relates to a rear lighting and/or signaling device, notably for a motor vehicle, comprising a light source, a transmission surface and means for distributing at least a part of the light from the source on the transmission surface, the distribution means comprising a matrix of micromirrors that can each be driven according to at least two different inclination positions. Another source is present and a mode of operation allows the illumination of a part of the micromirrors by the source and another part by the source.
摘要:
A lighting and/or signaling device, especially for automotive vehicle, comprising an optical system furnished with a light source (S) configured to emit a light beam in an initial color (F1), the device furthermore comprising a glass cover (3) disposed so as to be traversed by the beam, the glass cover (3) being colored in such a way as to transmit the beam in a resulting color (F2). According to the invention the device furthermore comprises a filter configured so as to make the resulting color (F2) of beam closely similar to its initial color (F1).
摘要:
A lighting device for an automotive vehicle comprising at least two semiconductor light sources that can be selectively activated and at least one optic for shaping at least a portion of the light rays emitted by either or both of the light sources with the aim of generating at least two lighting and/or signaling functions. The device is configured so that a first function requires the activation of the first semiconductor light source and a second function requires the activation of the second semiconductor light source. At least one of the light sources is a semiconductor light-source comprising a light-emitting rods.
摘要:
A system and method for controlling an overall light beam emitted by an automotive vehicle headlamp and formed from selectively activatable beam segments produced independently from one another by illuminating means borne by the headlamp, the segments together forming an overall light beam when they are all activated and placed successively side-by-side.The instantaneous speed of the vehicle is compared to a first preset speed threshold, and a zone of high light intensity to be produced when the instantaneous speed is higher than the first preset speed threshold is determined.
摘要:
A part for an illuminating and/or signaling device of an automotive vehicle, comprising at least one body made of a polymer, at least one section of this body being able, when the part is mounted inside the illuminating device, to be exposed to rays from the sun after they have been focused by a focusing device of the illuminating device, characterized in that the section comprises a reflecting means the reflection coefficient of which is higher than 90%.
摘要:
A lighting system that includes a light source able to generate a light beam and means for scanning the light beam incorporating at least one oscillating reflective body for deflecting the path of the beam.The oscillating reflective body is moved by deformations of a piezoelectric operating member. The means for scanning the light beam also have optical means for amplifying the deflection of the path of the light beam positioned downstream of the reflective body, in relation to the propagation direction of the light beam.
摘要:
A lighting and/or signaling device and method comprising an opaque element that can move between at least two positions, one of the positions interposing the opaque element between the main light source and the optical focusing device, in which the opaque element is arranged so that when it is interposed between the main light source and the optical focusing device it prevents rays originating from outside the lighting and/or signaling device from being focused, especially in a line or spot, by the optical focusing device, in order to prevent degradation of the lighting and/or signaling device.
