Abstract
The invention relates to a system for projecting light beams for a vehicle, including a first device configured to generate a first beam which performs a signaling function and a second device configured to generate at least a second beam for projecting a pattern, with the first device including at least one refractive optical member for shaping the first beam and in that the second device includes at least one optical element having a controlled pattern-generating surface to deflect light rays from a light source, this generating surface having local variations arranged so as to form a predetermined pattern in the second beam.
Claims11
A system for projecting light beams for a vehicle, comprising a first device configured to generate a first beam which performs a signaling function and a second device configured to generate at least a second beam for projecting a pattern with a plurality of portions spaced apart from each other, with the first device including at least one refractive optical member for shaping the first beam, and in that the second device includes at least one optical element having a controlled pattern-generating surface configured to deflect light rays from a light source, the generating surface having local variations arranged so as to form a predetermined pattern in the second beam, wherein the first device and the second device include at least one common dioptric optical element that includes the controlled pattern-generating surface, with the at least one common dioptric optical element being a lens or an outer lens sealing a headlamp unit.
A system for projecting light beams for a vehicle, comprising a first device configured to generate a first beam which performs a signaling function and a second device configured to generate at least a second beam for projecting a pattern, with the first device including at least one refractive optical member for shaping the first beam, and in that the second device includes at least one optical element having a controlled pattern-generating surface configured to deflect light rays from a light source, the generating surface having local variations arranged so as to form a predetermined pattern in the second beam, wherein the first device and the second device include at least one common optical element with the at least one common optical element being a waveguide.
A system for projecting light beams for a vehicle, comprising a first device configured to generate a first beam which performs a signaling function and a second device configured to generate at least a second beam for projecting a pattern, with the first device including at least one refractive optical member for shaping the first beam, and in that the second device includes at least one optical element having a controlled pattern-generating surface configured to deflect light rays from a light source, the generating surface having local variations arranged so as to form a predetermined pattern in the second beam, wherein the second device includes a plurality of optical elements each having a generating surface that are spaced apart along a long dimension of a common optical element.
