They are to be considered in the operating conditions of the device in a vehicle.
- the use of these words does not mean that slight variations around the vertical and horizontal directions are excluded from the invention.

- Each zone is defined in particular by a different portion of the surface of the output diopter and is configured so that the projection of the beam differs, in its shape, as it is projected via the surface of the dioptre output of the first zone or that of the second zone. More precisely, the projection differs between these two zones of the optical element by a different spreading.

- this case is not limiting and the surface defining the input diopter 8 could also be specific so as to operate the differentiation between the two zones of the invention.
- the optical element in the form of a lens 1 comprises, on its outer surface constituting the exit diopter 9, a first surface portion defining the first zone 7 and a second surface portion. defining the second zone, here in the form of two lateral portions 6a, 6b.
- the lateral portions 6a, 6b are configured to frame the first zone 7.
- this frame is made by juxtaposition in a horizontal direction. In the example, this corresponds to a sequence of a lateral portion 6a, the first zone 7 and the lateral portion 6b in the Y direction.
- the lateral portion 6a, the first zone 7 and the lateral portion 6b can be linked in the vertical direction corresponding here to the direction Z.
- the differentiation of the first zone 7 and the second zone comprising the lateral portions 6a, 6b takes place at the exit diopter 9 by a difference in convexity.
- FIG. 1 gives a general view of this differentiation and reveals connection zones 10a, 10b at the junction zones between the first zone 7 and the lateral portions 6a, 6b.
- the connection zones are also visible in cross section in FIG. 2. They are due to different shapes and in particular different convexities of the exit diopter 9 between the two zones.
- FIG. 2 gives two section lines respectively AA and AB respectively revealing in FIG. 3 and in FIG. 4 the two different convexities at the surface of the exit diopter 9. For example, the radius of curvature is greater on the lateral parts 6a.
- connection zones 10a, 10b constituting variations of lens thickness 1 in the X direction and forming zones.

- a difference in radius of curvature of the order of 10 to 20% gives satisfaction.
- the surface of the lens 1 forming the input diopter 8 may also have a difference in curvature between the central portion of the first zone 7 and the lateral portions 6a, 6b.
- the central portion substantially around the optical axis 16 may comprise a radius of curvature greater than that of the side portions 6a, 6b, for example in a proportion of the order of 15 to 30%.
- the optical element is advantageously configured to produce, as a whole, a focus.
- two light sources 3, 4 are represented in the form of a chip of the monochip type using a support oriented along a plane substantially parallel to the X, Y plane and downward directed LEDs. that is, along the Z direction for their average emission radius.
- These light sources 3, 4 advantageously cooperate in a particular way with the reflector 2 here placed below the sources 3, 4. This placement of the reflector 2 below allows the projection of light rays by reflection of the primary rays from the light sources 3, 4 without making visible the sources 3 , 4 directly from the outside of the device.
- the general function of the reflector 2 is to produce, on the basis of primary rays 13 appearing in FIGS. 3, 4, reflected rays 14 able, at least in part, to impact the input diopter 8 of the optical element.
- the reflector 2 provides a first transformation of the light rays generated by the sources 3, 4.
- a first advantageous transformation carried out by the reflector 2 is a focus.
- the reflector 2 is configured to focus the primary rays 13 along a line of focus 17 advantageously intermediate the reflector 2 and the input diopter 8.
- focussing is carried out along X, Z planes.
- a reflector form 2 having, in a vertical section corresponding to the X, Z plane, a substantially elliptical or strictly elliptical shape may be used. In this way, by placing the light sources 3, 4 substantially at a focus of the ellipse, it is possible to produce a focus on the line 17 at which the image foci are located.
- FIG. 2 gives an illustration of the line 17 seen in section in the plane direction X, Y.
- Another transformation preferably allowed by the reflector 2 is a colimation. More precisely, in a plane advantageously perpendicular to the plane in which the previously indicated focusing is effected, the primary rays 13 are reflected so as to have a preferred propagation direction, preferably parallel to the optical axis 16 corresponding to the direction X. This transformation is revealed in FIG. 2 at which a plurality of reflected rays 14 are represented in parallel at the exit of reflector 2. To achieve this, it is possible to give reflector 2, in horizontal section corresponding to plane X, Y, a parabolic form. In this case, the light sources 3, 4 are advantageously placed at or near the foci of these parabolic sections so as to produce the reflection in the preferred direction.
- the entire reflector 2 preferably has the combination of elliptical and parabolic sections indicated above continuously over its entire surface.
- two light sources 3, 4 are present.
- an optional feature is to map one of the light sources 3 with a first lateral portion 1 1 a of the reflector 2 and a second light source 4 in correspondence with a second lateral reflector portion 1 1 b.
- a reflector is formed substantially in two parts 1 1 a, 1 1 b these parts being preferably symmetrical relative to the optical axis 16 and defining between them a junction line 12, an example of which is visible in FIG. 2.
- the junction line is not given in Figure 1.
- Each lateral portion 11a, 11b advantageously adopts its own configuration in parabolic horizontal section and in elliptical vertical section.
- the junction line 12 is thus preferably a zone of points of recoil between two concave surfaces going up in direction Z and joining together forming a cusp line at the junction line 12.
- FIG. 2 also gives an example of placement of foci 20a, 20b respectively corresponding to the focus of the parabolic section of the side portion 1 1a and the side portion 1 1b.
- the sources 3, 4 are located offset relative to the foci 20a, 20b. More particularly, an option is to separate the light sources 3, 4 relative to the foci 20a, 20b so that the sources 3, 4 are farther apart than the foci 20a, 20b, For example in a proportion of the order of 1 to 3 times the offsets of the outbreaks.
- the foci 20a, 20b are positioned symmetrically around the junction line 10.
- the sources 3, 4 are also symmetrical relative to the junction line 12. The assembly is advantageously aligned in the Y direction so that the sources 3, 4 and the foci 20a, 20b are located on the same line.
- FIGS. 3, 4 enable the result of the light emission to be compared according to whether the rays are projected by the lateral parts 6a, 6b or by the first zone 7.
- the primary rays 13 are reflected by the reflector 2 in a focused manner on the line 17 and impacts the input diopter 8.
- the projected rays 15 are focused along the line of focus 18.
- the latter is located relatively far away from the diopter 9.
- This central portion may for example be used to project a portion of the beam in a relatively concentrated manner and away from the device, for example to form a preponderant part of an additional beam.
- the vertical angular deflection of the beam produced in this part is greater. This can for example be used to achieve a predominant part of a signaling function requiring greater spatial coverage including greater vertical coverage, for example for a DRL function or a city lamp function.
- the invention makes it possible to define a projected beam of specific and differentiated shape according to the zone of the optical element in which the light rays originating at the origin of the light sources 3, 4 pass.
- a preferred application of the invention relates to the projection of several types of beams.
- the envelope of the output beam is adapted to the realization of a plurality of functions. Therefore, it is then sufficient to control the device with the brightness level corresponding to the desired lighting function to reach the output of the corresponding beam.
- a first of these beams is a city lamp type beam obtained with a relatively low intensity for the control of the light sources, for example 5 lumens for each.
- a second function is a beam of daylight type for which the sources are advantageously controlled to each produce a flow of 50 lumens.
- a third stream may be an additional road-type beam, more powerful than the previous two and obtained for example with an intensity from the light sources 3, 4 of about 150 lumens each.
- the invention advantageously comprises a control circuit of the light source or sources 3, 4 so as to produce several brightness levels.
- the circuit makes it possible to modify the power supply of the light sources 3, 4 so as to vary continuously or in stages the generated light intensity. As indicated above, it follows the formation of a plurality of beams performing different functions while being produced by a unique optical device. In particular, it is not necessary according to the invention to use moving parts for example to differentiate the orientation of the light rays according to the desired lighting function.
