Abstract
A lighting device for projecting an image onto the ground around a motor vehicle. The lighting device includes a light source capable of producing a light beam, a first mask with a first pattern and a second pattern, the first mask being movable between a first position and a second position, a second mask with a third pattern and a fourth pattern, the second mask being movable between a first position and a second position, an actuator configured to move the first mask between its first position and its second position, and a drive means configured to optionally move the second mask between its first position and its second position at the same time as the first mask.
Claims8
A luminous device for projecting an image onto the ground around an automotive vehicle, the luminous device comprising:
- a light source capable of producing a light beam,
- a first mask including a first pattern and at least one second pattern, the first mask being movable between a first position and at least a second position, the first pattern being positioned through the light beam when the first mask is in the first position, the second pattern being positioned through the light beam when the first mask is in the second position,
- a second mask including a third pattern and at least one fourth pattern, the second mask being movable between a third position and at least a fourth position, the third pattern being positioned through the light beam when the second mask is in the third position, the fourth pattern being positioned through the light beam when the second mask is in the fourth position,
- an actuator configured to move the first mask between the first position and at least the second position,
- a drive means configured to optionally move the second mask between the third position and at least the fourth position at the same time as the first mask,
- wherein the first pattern and/or the second pattern includes at least one opaque zone, a first transparent zone and at least one second transparent zone, the second transparent zone being separated from the first transparent zone by the opaque zone of the first mask, the third pattern and/or the fourth pattern includes a transparent zone and an opaque zone, the transparent zone of the third pattern and/or of the fourth pattern being able to extend face-to-face with the first transparent zone of the first pattern and/or of the second pattern, and the opaque zone of the third pattern and/or of the fourth pattern being able to extend face-to-face with the second transparent zone of the first pattern and/or of the second pattern.
