Abstract
The invention relates to a light-emitting device for a motor vehicle. The device includes a first module including a first light source and a first collector for reflecting the emitted light in the form of a first beam, and a first mirror for forming a first virtual image of the first collector. The device also includes a second module including a second light source and a second collector for reflecting emitted light in the form of a second beam, and a second mirror for forming a second virtual image, the second virtual image being contiguous with the first virtual image. The device further includes a projecting optical system arranged to form, on the road, an image of each of the virtual images.
Claims12
A luminous device of an automotive vehicle comprising:
- a first luminous module including
- a first light source and a first collector with a reflective surface arranged to collect and reflect light emitted by the first light source in the form of a first light beam, and
- a first mirror arranged to form a first virtual image of the reflective surface of the first collector;
- a second luminous module including
- a second light source and a second collector with a reflective surface arranged to collect and reflect light emitted by the second light source in the form of a second light beam, and
- a second mirror arranged to form a second virtual image of the reflective surface of the second collector, the second virtual image being contiguous with or partially superposing the first virtual image;
- wherein the first collector has a rear edge and the second collector has a rear edge;
- an optical projection system associated with the first luminous module and the second luminous module, the optical projection system being arranged to project the first light beam and the second light beams;
- the optical projection system being arranged to form a road image on the road of each of the virtual images formed by the first and second mirrors;
- wherein the first mirror and the second mirror are oriented so as to reflect the first and second light beams in a same given direction, such that the first and second light sources are ranged so as to emit light in a direction opposing the same given direction.
