- FIG. 2 is a perspective view of the components used in a lighting module according to the invention.
- FIG. 3 is a schematic view of a projector incorporating three lighting modules according to the invention.
- FIG. 4 is a view showing a light projection generated by a lighting system comprising two projectors according to the invention
- FIG. 5 is a perspective and front view of a projector incorporating five lighting modules according to the invention.
- FIG. 1 illustrates a lighting module 1 intended to equip a motor vehicle, in particular by being installed inside a front headlight of the vehicle.
- This headlamp is capable of emitting one or more beams, in particular an optical axis-type beam referenced 2.
- the road-type beam is here implemented by the lighting module (s) 1 embedded in the headlamp.
- Such a lighting module 1 participates in the implementation of a function
- ADB i.e. selective switching on and off of one or more light strips within a road-type beam, so as to avoid dazzling a crossover vehicle or vehicle, while maintaining the level of illumination of the road function on either side of the crossed vehicle or
- This lighting module 1 ensures the provision of at least a first beam 3 and a second light beam 4, these beams each forming a luminous strip of rectangular shape, or substantially rectangular, respectively named first light strip 5 and second light strip 6. These light strips are here made visible by projection on a 5 screen perpendicular to the optical axis 2 and located for example 25 meters from the lighting module 1.
- a light band is formed by a zone illuminated by the lighting module 1 which extends between two lines of contrast. The latter thus border the light strip concerned and delimit it at least in vertical directions, or substantially vertical.
- the lighting module 1 is able to generate a light beam 7 which is formed by the combination of light bands generated by the lighting module 1.
- the lighting module 1 comprises at least a first light source 8 and a second light source 9.
- Such light sources are advantageously formed by light-emitting diodes.
- These light sources 8, 9 can each be secured on separate supports.
- the light sources are integral with the same support 10, the latter being for example a printed circuit board on which a plurality of conductive electrical tracks used to supply the light sources electrically.
- Each light source 8, 9 may have a rectangular shape, for example square.
- these light sources are thus defined by two dimensions referenced L and A in FIG. It will be noted that these dimensions are identical for all the light sources constituting the lighting module 1.
- the dimension L defines the width and the dimension A defines the length of the light source considered.
- the width L thus extends between two parallel edges of the light source, these edges being also parallel to, or substantially parallel to, the optical axis 2. The measurement of this width L therefore takes place in a direction perpendicular to the optical axis 2 passing through the two edges.
- the length A extends between two parallel edges of the light source, where these edges are advantageously perpendicular to the optical axis 2.
- the measurement of this length A is carried out in a direction parallel to the optical axis passing through the two edges.
- the width L and the length A are determined relative to the emitting zone.
- the light sources 8, 9 are arranged in the lighting module so that there is a non-zero space between two light sources 8, 9 immediately adjacent. This space is materialized by a distance referenced D in FIG. This distance D extends between two edges side by side of two adjacent light sources. In other words, the distance D extends between an edge of the first light source 8 which is immediately contiguous to an edge of the second light source 9.
- This distance D between the first light source 8 and the second light source 9 is at the origin of an area or band unlit 1 1 located between the first light strip 5 and the second light strip 6.
- the width of this non-light strip 1 is measured on the screen perpendicular to the optical axis 2 and is thus determined by the distance D.
- This band is described as being unlit in the sense that the lighting module 1 does not project light rays towards this light.
- non-illuminated band 1 1 can be illuminated by another lighting module, as will be detailed in the description to come with reference to Figures 3 and 4.
- the distance D is determined by a mathematical formula connecting it directly to the width L defining the light sources, this width being identical for all light sources, with manufacturing tolerances. According to the invention, this distance D is equal to any value strictly between the width L multiplied by an integer N and the width L multiplied by the integer N plus one unit.
- the distance D is between 1.01 mm and 1.99 mm. If the width L is equal to 3 mm and the integer number N is chosen equal to 1, the distance D is between 3.01 mm and 5.99 mm.
- the width L of the light source may be equal to 1.4 mm.
- the distance D between two immediately adjacent light sources can be strictly greater than (N + 0.25) * L and strictly less than (N + 0.75) * L.
- the width L is equal to 2 mm and the integer N is equal to 2, the distance D will be between 4.51 mm and 5.49 mm.
- the distance D between two light sources immediately adjacent is equal to (N + 0.5) * L.
- light sources of width L equal to 1 mm and an integer N equal to 1 are chosen.
- the distance D is equal to 1.5 mm.
- Such an example is particularly suitable for a projector comprising five lighting modules 1 each comprising at least two light sources.
- the width of the unlit strip 1 1 is equal to 1.5 times the width of the light bands referenced 5 or 6.
- the width of the unlit strip 1 1 corresponds to a gap 1 angularly between adjacent contiguous lines of two adjacent light bands, for example the first light strip 5 with respect to the second light strip 6.
- the distance D is equal to 0.5 mm.
- a projector comprising three lighting modules 1 each comprising at least two light sources.
- the optical aberrations of the projection element also influence the optimum value of the distance D which can be adjusted to compensate for them.
- FIG. 1 shows the presence of a third light source 12 of identical structure and dimensions to the first and second light sources 8, 9. It goes without saying that this third light source 12 can be placed in the lighting module 1 so as to respect the mathematical relationships or examples presented above, and we can refer to the description above to define its relative position.
- This third light source 12 generates a third light beam 15 which is embodied by a third light strip 16 on the screen.
- An unlit area 17 is present between the first light strip 5 and the third light strip 16, the width of this unlit area 17 being dependent on the distance D which separates the third light source 12 from the first light source 8.
- FIG. 1 still shows components that can complete the lighting module 1 according to the invention.
- the lighting module 1 can thus comprise a reflection means 13 whose function is to collect the light rays emitted by the first light source 8, the second light source 9, and any additional light source which can for example be secured to the light source.
- a reflection means 13 is a reflector, for example a parabolic mirror, elliptical, complex surfaces or cylindrical horizontal axis. In the latter case, the reflector collects the light rays to form a virtual image of the light source, in the form of a band of a given height and a width equal to that of the light source.
- a projection device then projects this image onto the screen at 25m, the focal length of a projection device and the width of the light source determining the width of the light band, whereas this same focal length and the height of the light source determine the height of the light band.
- the reflector can be arranged so that the virtual image does not offer a luminance distribution identical to that of the light source, concentrating the beam on the lower part of the light strip.
- Such a structure makes it possible to obtain the desired distribution in the light bands, including a non-centered maximum and a progressive decay upwards.
- a single reflection means 13 makes it possible to send back the light beams emitted by the first light source 8 and by the second light source 9.
- the first lighting module 1 further comprises the projection device 14 whose function is to project the first beam 3, the second beam 4 and possibly all the other beams generated by additional light sources constituting the lighting module, for example.
- a projection device 14 may be a focusing device. It is therefore understood that it is a single projection device which participates in the formation of several light bands, in particular the first light strip 5 and the second light strip 6.
- such projection device 14 is a lens having in particular at least one convex face.
- FIG. 2 shows an exemplary embodiment of the lighting module 1 according to the invention.
- the support 10 is a plate or printed circuit board which receives on one and the same face the first light source 8, the second light source 9 and the third light source 12. These are rectangular-shaped light-emitting diodes.
- the support can also receive electronic components used for example for switching on or off these light sources in the ADB function.
- a shutter 18 Perpendicular to the plane of extension of the support 10, there can be found a shutter 18 whose function is to prevent a direct emission of the light rays generated by the light sources to the projection device 14.
- This shutter 18 may in particular have a reflective surface so as to return these rays to the reflection means 13.
- the projection device 14 is a lens having a first face 19 which directly faces the reflection means 13.
- This first face 19 is here for example cylindrical, vertical axis.
- the lens is delimited by a second face 20 which is opposite to the first face 19 relative to a body 21 of the lens.
- This second face 20 has a concave shape seen from the first face 19.
- the first, second and third light beams are emitted by the first, second and third light sources 8, 9 and 12 and strike a surface of the reflection means 13. The latter redirects them. to the projection device 14 to project on the road taken by the vehicle.

- the second lighting module 24 is the generator of a fourth light band 26, a fifth light band 27 and a sixth light band 28 of identical widths, the latter being commonly called secondary light bands.
