The subject inventive arrangement produces a light guide that may be of any curved shape that produces and obtains a lighting appearance of a uniform or homogenous lit appearance at the light exit face by using a single light source and a single light-reflective coupler. The present invention is premised on a light guide system that includes a light guide; a light source; and a coupler positioned at the light source that is configured to receive generated light. The coupler is adapted to produce a collimated light beam from the light source. A stepped reflective surface is formed along a light reflecting face of the light guide by a plurality of light reflective facets and a plurality of lateral surfaces, which are configured to receive and direct collimated light towards a light-emitting exit face. In addition, a number of light reflective facets are configured to collect collimated light at the light reflecting face's middle portion in intensity amounts less than collimated light at end portions of the light reflecting face.

Homogeneous light emission and light guide arrangement of an automobile vehicle for a uniform lit appearance

The present invention discloses an optical device for a motor vehicle comprising: a light guide; at least one collimator; at least one light source associated with each collimator; and at least one optical coupler having at least two reflecting facets. The optical coupler couples a collimator with the light guide at the light entry face of the light guide. The collimator is adapted to receive the light beam emitted by a light source and to collimate this beam; and directing the collimated beam towards the reflecting facets of the optical coupler. At least part of collimated light beam from the reflecting facets enters the light guide and directed towards the light exit face along an optical axis of the light guide. The optical device further comprises at least one aperture for diverting other part of the collimated light beam out of the light guide.

Optical device for a lighting and/or signalling device of an automobile vehicle

The present invention related to an optical device comprising: a light guide; at least one first light source and at least one second light source; at least one first optical coupler and at least one second optical coupler; and at least one collimator to generate a first collimated light beam and a second collimated light beam. The at least one first optical coupler is configured to receive the first collimated light beam and directs the first collimated light beam along a first optical axis towards a first region of the light exit face to perform a first photometric function. The at least one second optical coupler is configured to receive the second collimated light beam and directs the second collimated light beam along a second optical axis towards a second region of the light exit face to perform a second photometric function.

Optical device for an automobile vehicle

A light module, notably for a motor vehicle, including a first reflecting surface), of the elliptical type, with a first focus and a second focus; a second reflecting surface, of the parabolic type, with a focus corresponding to the second focus of the first reflecting surface; light rays emitted by a first light source located at the first focus of the first reflecting surface being reflected by the first and second reflecting surfaces to form a first light beam; and a third reflecting surface adjacent to the second focus of the first reflecting surface and configured to reflect, towards the second reflecting surface, light rays emitted by a second light source, in order to form a second light beam.

Bi-functional light module with common illuminated surface

The present invention relates to a lighting unit of an automotive headlamp comprising: a series of two or more reflectors arranged side by side and coincident with each other; at least two light sources are arranged per reflector and disposed such that each light source provides light rays to the reflector targeted immediately adjacent to a focal point of the corresponding reflector and on opposing sides of the focal point; and the at least two light sources for each reflector are rotationally arranged at a set positional angle relative to the at least two light sources of the coincident reflector to produce a centered output beam.
