Definitions

• the invention relates to a lighting device for a motor vehicle, the lighting device being configured to project an image such as a pictogram onto the ground.
• the first mask may comprise a generally circular shape, the patterns of the first mask being distributed around a center of the first mask.
• the second mask may comprise a generally circular shape, the patterns of the second mask being distributed around a center of the second mask.
• the first mask can extend in a first plane and in that the second mask can extend in a second plane, the second plane being parallel to the first plane and offset relative to the first plane.
• the first pattern may comprise at least one opaque zone and at least one transparent zone.
• the second pattern may comprise at least one opaque zone and at least one transparent zone.
• the drive means may comprise a first stop secured to the first mask, the first stop cooperating with a second stop secured to the second mask, so that the movement of the first mask causes the movement of the second mask when the first stop is resting against the second stop.
• Figure 4 is a schematic view of the superposition of the first mask and the second mask in a first configuration.
• Figure 12 is a schematic view of the superposition of the first mask and the second mask in a ninth configuration.
• Figure 15 is a schematic top view of the vehicle and a third image projected by the light device next to the vehicle.
• the first mask and/or the second mask could be movable in a movement other than rotation, for example movable in translation.
• the first mask and/or the second mask could be movable in rotation around a point which is not necessarily the center of the first mask and/or the second mask.
• the first mask and/or the second mask could be movable in rotation around a point arranged at an edge of the first mask, and/or respectively an edge of the second mask.
• the first mask and/or the second mask could comprise a shape other than a circular shape, for example a polygonal shape.
• the second mask could be positioned in front of the first mask following the direction of propagation of the light rays.
• these stop means, friction surfaces or magnetic elements no longer cooperate with the combined means of the first mask or the rotating shaft, so as to allow free rotation of the first mask without driving the second mask.
• the first mask which could be movable between a disengaged position and an engaged position.
• the actuator 12 can be controlled by the electronic control unit to rotate the first mask 5 in a first direction of rotation (corresponding to the clockwise direction in the figures) or on the contrary in a second direction (corresponding to counterclockwise direction).
• a first direction of rotation corresponding to the clockwise direction in the figures
• a second direction corresponding to counterclockwise direction
• the first stop 19 moves away from the second stop 20 and the rotation of the first mask does not cause any rotation of the second mask.
• Such a rotation results in the pattern 22 of the first mask being in the lighting zone Zl.
• the pattern 31 of the second mask remains in position in the lighting zone Z2.
• the first mask can also be controlled by the actuator so as to rotate a third of a turn clockwise.
• the first stop 19 presses on the second stop 20 and the rotation of the first mask causes the rotation of the second mask.
• the light device finds itself in a new configuration illustrated in Figure 7.
• the pattern 23 of the first mask is located in the lighting zone Zl and the pattern 32 of the second mask is located in the lighting zone Z2. This results in the projection on the ground of an image comprising two snowflake-shaped symbols.
• the first mask can be controlled by the actuator so as to rotate a third of a turn counterclockwise.
• the first stop 19 moves away from the second stop 20 and the rotation of the first mask does not cause the rotation of the second mask.
• the light device finds itself in a new configuration illustrated in Figure 8.
• the pattern 22 of the first mask is located in the lighting zone ZI and the pattern 32 of the second mask is located in the lighting zone Z2.
• the opaque zone 34 of the pattern 32 of the second mask then covers the transparent zone 28D of the pattern 21 of the first mask.
• Such a pictogram means that the vehicle battery is two-thirds charged.
• a rotation of the first mask respectively by a third of a turn or two thirds of a turn in the counterclockwise direction makes it possible to obtain the configurations of Figures 10 and 11.
• the configuration of Figure 10 leads to the projection on the ground of an image representing a stack with a single illuminated floor, as appears in Figure 15.
• the configuration of Figure 12 can be obtained from the configuration of Figure 8 by rotating the first mask of a third of a turn counterclockwise.
• the invention therefore proposes to project images on the ground thanks to the superposition of two patterns belonging to two distinct masks.
• each of the patterns of the first mask can be combined with each of the patterns of the second mask so as to produce a different image.
• the invention thus makes it possible to obtain a high number of different images from a limited number of patterns.
• the first mask and the second mask each comprise three patterns. Alternatively, this number could be different.
• the number of patterns appearing on the first mask is not necessarily equal to the number of patterns appearing on the second mask. If N designates the number of patterns present on the first mask and P designates the number of patterns present on the second mask, the number of different images can thus reach N x P.
• the patterns 21, 22, 23 are advantageously formed by a plurality of transparent zones separated from each other by opaque zones.
• the light device 2 thus tolerates a certain inaccuracy of positioning between the first mask 5 and the second mask 6.
• the opaque zones 34 of the second mask can be slightly offset relative to the transparent zones of the first mask which they cover provided that the opaque areas of the second mask are both large enough to cover the transparent areas of the first mask despite the offset, and provided that the opaque areas of the second mask are not too large so as not to protrude onto another transparent area of the first mask .
• the wider the opaque zones 27 separating the different transparent zones of the first mask the more the light device will be able to tolerate significant positioning shifts between the first mask and the second mask without altering the quality of the image projected on the ground.
• the stops 19 and 20 make it possible to obtain very good positioning of the second mask relative to the first mask when they are supported against each other. We can therefore obtain very precise positioning of the masks for certain configurations independently of the precision of the actuator 12.
• the configurations of Figures 4, 7 and 9 benefit from this particularly precise relative positioning. We could therefore consider for these configurations a superposition of patterns requiring greater precision.
• each mask includes fewer patterns, each pattern can be larger, improving the resolution of the projected image.
• the light source can optionally be turned off during movement of the first mask so as to mask the transition between the projected images. Whatever the initial configuration, a new configuration can be obtained by rotating the first mask in one direction then in another.
• the memory 16 of the electronic control unit 15 can include a series of instructions making it possible to reach any configuration of the light device 2 from any other configuration. We thus manage to control the position of the first mask 5 and the second mask 6 with a single actuator.
• the light device could then comprise a first 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 and a second drive means configured to optionally move the third mask between its first position and its second position at the same time as the first mask and/or at the same time as the second mask.
