    Abstract: A luminous motor-vehicle system including an optical module and aims to compensate for undesirable movement or deformation effects caused by the manufacturing tolerances of the optical portion. The module includes an imaging device provided with a pixelated spatial modulator, which is illuminated by a source, and a projecting optic. A control unit for controlling the modulator receives first display commands that are representative of an image to be projected. This unit converts each first display command into a second display command taking into account correction parameters, which are predefined on the basis of an identification of geometric defects specific to the projecting optic. The control unit controls the modulator, which may be a digital micromirror device, depending on the second display commands in order that the image actually projected by the imaging device corresponds to the image to be projected.

    Abstract: A light-emitting device, especially for lighting and/or signaling for a motor vehicle, includes at least a first electroluminescent module and a second electroluminescent module energized in series. Each electroluminescent module includes, in parallel: a first branch having a light source having a first direct threshold voltage beyond which the light source is gated on, and a second branch having an element such that the voltage on the terminals of the element is less than the first direct threshold voltage of the light source. A third branch has a timing module able to time a predetermined period and modify, at the end of the predetermined period, an overall impedance of the second branch so that a voltage in the second branch is greater than the first direct threshold voltage of the light source. The predetermined period in the first electroluminescent module is less than that of the second electroluminescent module.

    Abstract: A lighting and/or signaling module for an automobile vehicle, the module comprising a light source e, a reflecting surface and a toroidal lens. The reflecting surface is calculated in such a manner that the rays coming from the module, reflected then transmitted by the lens, are perpendicular to and encounter a circular arc A. This geometry of the outgoing rays endows them with a toroidal wavefront which allows the principle of constancy and of reversibility of the light path (Fermat's principle) to be applied and, consequently, a straightforward calculation of the reflecting surface. The beam thus produced can notably provide a daytime running light or, alternatively, a direction indicator function. The module may comprise another lighting function of the high-beam type using another portion of the lens.
