- these flashing lights When they operate simultaneously, these flashing lights also provide a second function called “distress signal” or “Warning” which allows to report an imminent danger to other users.
- the drivers of the surrounding vehicles may have some difficulty in discerning whether the signal emitted by said automobile constitutes a distress signal or a simple signal of change of light. direction.
- flashers comprising a series of horizontally aligned light emitting diodes (LEDs) which are excited progressively and cumulatively until the ignition of the light is complete. the set of diodes, so as to cause a sweeping effect on an outer side of the vehicle when the blinking function is activated. This sweeping effect that accompanies the blinking flashing "classic", provides users with clear information identifiable quickly even at great distance.
- LEDs light emitting diodes
- this type of steering indicator is currently reserved for high-end motor vehicles, because of its particularly high cost, due in particular to the large number of light-emitting diodes that it includes (typically around 30), and the need to provide an on-board electronic control board.

- said light concentrator is formed at least in part by the concave and reflecting inner face of a rear wall situated facing the light source and the output screen;
- said light source is only lit when said opening is opposite at least a portion of the output screen
- said light concentrator is formed at least in part by a convergent or Fresnel lens
- the focus axis of said lens coincides with the axis of said light source
- said light concentrator is formed at least in part by the reflecting inner face of said cover;
- said opening extends over a narrow angular section and has a rectangular contour, so that said projection zone consists of a narrow strip moving laterally on the exit screen;
- said cover is cylindrical
- said cache has a parabolic section; the axis of rotation of said parabolic section cover is coincident with its focus axis and with that of said light source;
- said light source is constituted by an incandescent lamp, a halogen lamp, or even by a multitude of grouped light-emitting diodes;

- FIG. 12 represents a perspective view of the cover that comprises the lateral indicator of FIG. 11;
- FIG. 13 shows a perspective view of a lateral direction indicator according to a third embodiment of the invention.
- Figures 1 to 8 show a direction indicator 1 according to a first preferred embodiment of the invention, mounted in a lateral housing provided at the front or rear of a vehicle not shown.
- the direction indicator 1 comprises in a housing 2, a flashing light source 3 emitting light rays 4, a concentrator 5 of light rays 4, a cover 6 surrounding the light source 3 and an output screen 7 of the light beam; the term "light beam” denotes in this application, the set of light rays 4 that are actually emitted by the direction indicator 1 at the output screen 7 ( Figures 6 to 8).
- the light beam concentrator is constituted by the concave and reflecting inner face 5 of the rear wall 8 of the housing 2 situated opposite the light source 3 and the output screen 7.
- a first lateral end of the output screen 7 (that shown on the left in the figures) is contiguous to a first lateral end of the rear wall 8 of the housing 2; while the opposite lateral ends of the screen 7 and the rear wall 8 (shown on the right in the figures) are connected by an intermediate wall 9.
- the cover 6 has an opaque cylindrical wall mounted in rotation relative to the bulb 3 about its axis of revolution AA vertical and perpendicular to the bottom wall 10 of the housing 2.
- the cylindrical wall of the cover 6 has a rectangular opening 11 extending here over its entire height and an angular section of about 30 °. Alternatively, the height and the angular section of this opening may of course be different.
- the lower part of the cover 6 comprises a gear 12 which can be engrained by the drive gear 13 of an electric motor 14, so as to cause the rotation of the cover 6.
- This gear 12 is located under the casing 2 thanks to a circular opening 15 made in the bottom wall 10 of this casing 2.
- the light source is formed by an incandescent bulb 3 extending along an axis perpendicular to the bottom wall 10 of the housing 2, this axis coinciding with the axis of revolution A-A of the cover 6.
- this bulb 3 is also located outside the housing 2 under its bottom wall 10, the latter being mounted in a substantially cylindrical fixed sleeve 16.
- the speed of rotation of the cover 6 is constant and the blinking cycle of the blister 3 is predetermined so that this blister 3 is off when the opening 11 of the cover 6 is oriented towards the exit screen 7, and illuminated during the remainder of the cache rotation cycle 6.
- the bulb 3 turns on as soon as the opening 11 of this cover 6 comes opposite the right-hand lateral end of the rear wall 8 of the housing 2.
- the light rays 4 passing through the opening 11 of the cover 6 strike and reflect on the internal face 5 of this rear wall 8 which concentrates them in a narrow light beam illuminating a light strip 17 located at the right-hand end of the output screen 7.
- the concavity of the rear wall 8 is predetermined here so that the width of the projection zone 17 remains almost constant during its lateral displacement (FIGS. 6, 7 and 8).
- the lateral direction indicator illustrated in these figures is similar to the indicator 1 previously described except that the inner face 5 'of the rear wall 8' of the housing 2 'is not reflective and that the cover 6 'is shaped differently.
- the continuation and on the drawings one kept the same references for the identical elements, whereas the similar elements are decked with a premium.
- the cover 6 here retains the same cylindrical shape as the cover 6, but its opening 11 is covered by a convergent or Fresnel lens 20 whose focal axis A'-A' merges with the axis of rotation of the cover 6 'and with that of the bulb 3.
- This lens 20 constitutes here the light concentrator, the set of radii 4 through the spring emerging from the cover 6 'in the form of a narrow unidirectional light beam ( Figure 10).
- the blinking cycle of the bulb 3 is also different since the latter is lit only when the opening 11 and the lens 20 of the cover 6 'are next to the exit screen 7.
- the narrow light beam emerging through the opening 11 and the lens 20 is thus projected on the output screen 7, the projection area of this beam moving laterally on the screen 7 with the rotation of the cover 6 '.
- the cover 6 rotates here clockwise.
- the lateral direction indicator 1 "illustrated in these figures is similar to the indicator which has just been described except that the cover 6" is shaped differently.
- the continuation and on the drawings one kept the same references for the identical elements, whereas the similar elements are decked out of a double premium.
- the cover 6 here has a wall with a paraboloidal section rotated about its focal axis A" - A “coinciding with the axis of the bulb 3. Furthermore, the light concentrator is here formed by the reflective inner face 21 of this cover 6 ", the set of light rays 4 reflecting on this inner face 21 emerging from the opening 11" of the cover 6 "in the form of a narrow unidirectional light beam.
- This variant embodiment thus makes it possible to obtain a dynamic luminous effect of scanning of the output screen which differs slightly from the effect obtained with the indicator.
- FIGS. 9 and 10 as well as its variant shown in FIGS. 10, 11 have a slightly higher cost price but are particularly advantageous to implement when the available volume is limited and it It is not possible to provide at the rear of the cover, a concave reflecting wall such as the wall 8.
- the lateral direction indicator "illustrated in this FIG. 13 is similar to the indicator 1 previously described except that the internal face 5" 'of the rear wall 8 "' of the housing 2" 'is not reflective. and that the cover 6 "'is shaped differently
- the same references have been kept for the identical elements, while the similar elements are decked with a triple premium.
- the cover 6 "' is identical to the cover 6 of the first embodiment except for its opening 11"' which extends over a much larger angular portion, the latter being predetermined so that that the opening 11 "'is able to be facing the entire output screen 7 for a short period of its rotation cycle.
- the light concentrator is here formed by the reflective inner face 23 of the cylindrical wall of this cover 6 "', the set of light rays reflecting on this inner face emerging from the opening 11 "'in the form of an indirect light flux which is added to the direct light flux.
- the flashing cycle of the bulb 3 is calculated so that it is lit when the opening 11 "'of the cover 6"' is opposite at least a part of the exit screen 7.
- the projection area 17"' s' extends the entire screen 7.
- the continued rotation of the cache 6 "'causes a gradual decrease in the projection area 17"' by the right of the screen, until its disappearance when the opening 11 "'ceases completely to watch the screen 7.
- the concentrator can be formed by a combination of several different concentrators.
- the back wall of the housing and the cover may both have a concave and reflective inner face to enhance the concentration of the light beam reaching the screen.
- the light source is of a different type, the latter may in particular be constituted by a halogen bulb or a plurality of LEDs grouped together;
- the axis of rotation of the cover is offset with respect to the axis of the light source while remaining parallel to the latter, which makes it possible to modulate the kinematic effect by causing an acceleration or a deceleration of the scanning of the light source; light beam scanning the screen; the speed of rotation of the mask varies over a complete cycle of rotation, which also makes it possible to modulate the kinematic effect by causing an acceleration or a deceleration of the scanning of the light beam traversing the screen;
- the shape of the cache is different, the latter may in particular have an elliptical section;
- the contour of the opening is not rectangular, the latter being for example circular or triangular; and or
- the output screen is diffusive type or provided streaks oriented vertically and / or horizontally.
