Abstract
A lighting module intended to be placed behind a translucent or transparent outer lens or window, the module including: a place for at least one light source that is able to emit light rays; and an optical system that is able to deviate the light rays emitted by the one or more light sources so as to form a light beam along an optical axis of the module, the optical system extending in a main direction that is transverse to the optical axis and including an exit face for rays. The exit face of the optical system has in sagittal cross section a concave or convex curved general profile.
Claims20
A lighting module intended to be placed behind a translucent or transparent outer lens or window, said module comprising:
- a place for at least one light source that is configured to emit light rays;
- and
- an optical system that is configured to deviate the light rays emitted by the one or more light sources to form a light beam along an optical axis of the module, said optical system extending in a main direction that is transverse to the optical axis and comprising a first optical element and a second optical element;
- wherein:
- the first optical element includes a first entrance face to deviate the light rays that are emitted by the light source along the optical axis and a first exit face having Fresnel echelons to control spreading of the light rays along the main direction, and
- the second optical element includes a second entrance face having Fresnel echelons to receive and deviate the light rays originating from the first optical element, and a second exit face with a curved profile to distribute the light rays away from the optical system, the light rays being distributed away in one of a dispersing way and a converging way.
A lighting device for a motor vehicle, said device comprising:
- a housing and a lighting module, wherein
- the housing is configured to contain the light module;
- and
- the lighting module includes at least one light source that is configured to emit light rays, and an optical system that is configured to deviate the light rays emitted by the one or more light sources to form a light beam along an optical axis of the module, said optical system extending in a main direction that is transverse to the optical axis and comprising a first optical element, a shield and a second optical element,
- wherein:
- the first optical element includes a first entrance face to deviate the light rays that are emitted by the light source along the optical axis and a first exit face to control spreading of the light rays along the main direction;
- the second optical element includes a second entrance face to receive and deviate the light rays transmitted by the first optical element, and a second exit face with a curved profile to transmit the light rays away from the optical system;
- and
- the shield is connected to the first optical element and positioned to cover the second optical element.
