Definitions
- the invention relates to a motor vehicle lighting system which is capable of producing a light beam projecting forward an image comprising at least one horizontal row of illumination units
- Such a light beam is also called a pixel beam or “multibeam” in English.
- these illumination units are arranged side by side in a horizontal row. There may be one or more horizontal rows of illumination units.
- the off or on state of the corresponding illumination unit is controlled.
- the beam is then made up of a plurality of illumination units, turned on or off depending on the presence of other vehicles in the emission zone.
- US2008198574A1 shows such a light system.
- the light module capable of generating such a light beam is often used in addition to a light module producing a portion of the driving beam in front lighting devices to achieve an adaptive lighting function, also called "Adaptive Driving Beam » or ADB in English.
- a lower portion which can come from another module, illuminates below the horizon and the lit illumination units complete the lighting above this lower portion and the horizon so as to form a long range beam.
- the illumination units can then be turned off so as to create a shadow zone where there is another vehicle being followed or coming in the opposite direction. Consequently, the risk of dazzling the driver is reduced. from the other vehicle while maintaining good visibility of the road thanks to the lighting units not being turned off.
- the light module forming a pixelated light beam can also be used in addition to a light module forming a passing beam, also called code beam, or a lower portion of the passing beam.
- the pixelated light beam can form a dynamic bend distribution in order to achieve a dynamic bending function, or also called “dynamic bending light” or DBL in English, allowing the light beam to follow the curvature of the bends followed by the vehicle.
- the aforementioned ADB or DBL functions are lighting functions which improve the quality and comfort of visibility of the lighting device. There is therefore an increasing development of lighting devices integrating these functions.
- the photometry of a regulatory passing beam must include zones whose light intensity complies with the values imposed by the regulations.
- each illumination unit has a height greater than 0.57°, and for example from 0.7° to 1°, at least one illumination unit of said row superimposes with the BRR segment of the beam of basic crossing.
- the illumination unit provides additional light intensity to the area of the BRR segment. This risks causing the light intensity of the BRR segment to exceed the regulatory value and therefore making the lighting device non-compliant.
- the technical problem that the invention aims to solve is therefore to obtain a pixelated light beam which can be combined with a portion of a second light beam so as to produce a main lighting beam integrating an adaptive function, such as ADB , DBL, while forming a main lighting beam where the risks of light overintensity are reduced in certain areas, in particular which complies with regulations.
- an adaptive function such as ADB , DBL
- a first object of the invention is a light module for a motor vehicle intended to generate a light beam projecting an image forward.
- the image includes at least one horizontal row of illumination units.
- the light module is arranged so that a first illumination unit of a first horizontal row of illumination units comprises a lower and/or upper end which is offset vertically relative to a respectively lower and/or upper end of a second illumination unit of the same row. And, the first horizontal row of illumination units forms a high portion of a low beam.
- the offset can be applied to multiple illumination units in the row.
- one or more illumination units can be placed offset from the other units.
- the illumination units of the row of illumination units forming an upper portion of a passing beam are partly vertical to a horizontal cut-off line and partly offset relative to this horizontal line.
- the module can thus be arranged in such a way that the offset illumination unit(s) are those likely to overlap with certain regulated zones before being shifted. Such an arrangement goes against what is commonly applied and the prejudice of wanting to exactly align light strips and/or illumination units in a row.
- the offset illumination units are units that would intersect the BRR segment if the row contained only aligned units.
- the final main lighting beam therefore complies with the conditions imposed by the regulations.
- the invention also relates to a lighting device comprising a light module according to the invention.
- the terms “front”, “rear”, “lower”, “upper”, “top”, “bottom”, “side”, “transverse”, “right”, “left”, refer to the direction of emission of light out of the corresponding light module.
- the terms “upstream” and “downstream” refer to the direction of propagation of light in the object that cites them.
- the light module 1 capable of generating a light beam.
- the light module 1 emits the light beam longitudinally from the rear to the front, as illustrated by the arrow L on the figure 1 .
- Said beam projects forward an image composed of a plurality of lighting zones, also called units illumination, here, in rectangular shape and arranged in at least one horizontal row.
- the light beam generated by the light module 1 is, for example, lit in addition to a main lighting beam, such as a code beam or a high beam, to form a directional low beam, also called “Bending Light”, or an adaptive high beam, also called “Adaptive Driving Beam”.
- a main lighting beam such as a code beam or a high beam
- Adaptive Driving Beam an adaptive high beam

- Said three guides 210, 211 and 212 are hereinafter called the offset guides while the other guides are called the non-offset guides.
- the offset of the light guides causes the entry faces 230, 231 and 232 of the three offset guides 210, 211 and 212 to be placed higher than the entry faces 233 to 239 of the non-offset guides 213 to 219 .
- the heights of the entry faces 230, 231 and 232 of the offset guides 230, 231 and 232 remain identical to the other guides.

- Each secondary elementary light source 34 illuminates an area of the screen.
- each of the zones Z1 to Z10 and W1 to W10 therefore corresponds to the outputs of the light guides of the optical element 20.
- the areas on the screen Z1 to Z10 as well as W1 to W10 are also called the illumination units, or “pixels” in English.
- the illumination units Z1 to Z10 and W1 to W10 on the screen are arranged in two horizontal rows, including an upper row 4 and a lower row 5. In order to facilitate reading, the illumination units are shorthandly called " units”.
- the upper row 4 of units forms a distribution of a complementary driving beam. It contains the units Z1 to Z10 which respectively correspond to the outputs of the bottom row 22 of the optical element 20, therefore to the light sources of the second row 16.
- the unit Z1 corresponds to the projected image of the output of the light guide 229 located at the right end of the bottom row 22 on the Figure 3 .
- Unit Z2 corresponds to output 248 of light guide 228 located to the left of guide 229 at the right end.
- Unit Z3 corresponds to output 247 of guide 227 located to the left of guide 228 and so on up to unit Z10.
- Unit Z10 corresponds to output 240 of light guide 220 which is located to the far left of bottom row 22 on the Figure 3 .
- each of these units is delimited by peripheral edges of the output of the associated light guide.
- the shape of the entrance face remains similar to that of the exit.
- the units Z1 to Z10 of the upper row 4 have a shape identical to that of the outlets 240 to 249 of the lower row 22.
- the units Z1 to Z10 are rectangles whose height is greater than the width.
- zones Z1 and Z10 are wider than zones Z2 to Z9.
- the lower row 5 of units forms a high portion of a passing beam. In this example, it forms a dynamic turn distribution.
- the correspondence between units W1 to W10 and the Outputs from the top row 21 are done in a similar manner to the units Z1 to Z10 with the bottom row 22.
- the last three units W8 to W10 correspond respectively to the projected images of the outputs 330, 331 and 332 of the three offset guides 210, 211 and 212 described above.
- the three units W8 to W10 are offset vertically downwards relative to the other units W1 to W7 in the same row.
- the offset of the three units W8 to W10 is limited vertically in order to maintain rectilinear lighting at the level of the shoulder of the road. According to an example outside the scope of the invention, for optimal lighting of the aisle this offset is only 1° downwards, here 1° under the BRR segment.
- the upper edge 51 and the lower edge 52 of the unit considered are offset vertically downwards relative respectively to the upper edge 53 and the lower edge 54 of the non-offset units W1 to W7.
- each primary elementary light source 14 here each light-emitting diode 14
- the arrangement of the illumination units is carried out so that the photometric distribution complies with the conditions imposed by the UNECE R123 regulation.
- the three offset units W8 to W10 are below the BRR segment which is at 0.57°U and between 8°R and 20°R.
- these three offset units W8 to W10 are illuminated, they do not impact the light intensity of the BRR segment. Consequently, the light intensity measured at the BRR segment is not likely to exceed the value of 3550 cd as required by regulations.
- the light emitting diodes 14 are adjusted so that the units Z1 to Z10 of the upper row 4 are turned off.
- the units W1 to W10 of the lower row 5 can be selectively illuminated with the lower part B1 of the passing beam to produce an adaptive final passing beam integrating the BL function, otherwise called adaptive turning function.
- units W1 to W5 When a vehicle is driving in a straight line, units W1 to W5, mainly located to the left of the vertical axis V, are turned off while units W6 to W10, located to the right of the vertical axis V, are turned on so to form a high cut-off line of the passing beam. Since zones W8 to W10 are staggered, the light intensity at the BRR segment complies with current regulations.
- units W8 to W10 are lit progressively from left to right, until the end of the turn, here unit W10 located on the far right of the row when the bend is very pronounced.
- units W1 to W5 located to the left of the vertical axis V, are lit progressively from right to left, that is to say from unit W5 towards unit W1, or even up to 'to the W1 unit when the turn is very sharp, which allows better lighting on the driver's left side.
- the light module 1 of the lighting system generates an adaptive passing beam providing better visibility to the lighting during the turns while respecting the conditions imposed by the regulations.
- the light-emitting diodes 14 are adjusted so that all the units Z1 to Z10 and W1 to W10 are on, in particular when there is no vehicle traveling in front.
- the light-emitting diodes 14 are controlled so as to create a shadow zone at the location where the detected user is located. For example, to do this, units W3, W4 of the lower row 5 of units and units Z3 and Z4 of the upper row 4 of units are turned off.
- the units Z1 to Z10 then form an adaptive complementary main beam. They are lit to form a light beam located above the dynamic cornering beam formed by the units W1 to W10, itself located above a lower part B1 of a passing beam.
- the principle of shifting a few units in a row of units can be applied to the upper row 4 of units illustrated in figure 5 .
- At least one of the units Z1 to Z10 of the upper row 4 can be shifted. units vertically upwards.
- the guide(s), participating in generating the offset unit(s) in this upper row 4 include the output offset vertically downwards relative to the other outputs of the other guides.
- the guides to be shifted upwards are part of the guides 220 to 229 of the bottom row 22 of the optical element 20.
- the light system as well as the light module according to the invention can be configured so as to generate a light beam which conforms to other regulations, for example the federal motor vehicle safety standards of the United States, also called the “FMVSS” standards for “Federal Motor Vehicle Safety Standard” in English.
- FMVSS Federal Motor Vehicle Safety Standard
- the glare of drivers of oncoming vehicles is measured and linked to thresholds established from the FMVSS 108 standard.
- a final image I3 of a light beam which can be adapted to the FMVSS 108 standard.
- the light beam can be a passing beam and is in a configuration called according to this standard “VOR beam pattern” for left-hand driving .
- the final image I3 is represented in a reference R identical to the reference presented in Figure 5 .
- the passing beam is composed of a lower passing beam part B2 and an upper passing beam part H2.
- the upper part of the low beam is generated by a light module produced according to a second embodiment of the invention while the lower part B2 of the low beam is generated by a second light module known to those skilled in the art.
- the image I4 of the upper part of the passing beam comprises a single row 6 of eight illumination units X1 to UNITED STATES.
- the two units X5 and X6 are offset vertically downwards so that the upper ends 61 of said units X5 and °U. In this way, there is no light above the horizon between 1°R and 3°R.
- the light module carrying the optical part participating in generating the I3 image therefore complies with the FMVSS 108 standard.
- such a light module has a good chance of obtaining a good rating in a safety evaluation carried out by the Insurance Institute for Highway Safety (IIHS). in English. Indeed, apart from the shifted units X5 and X6, the other non-shifted units X1 to X4, X7 and X8 overlap the horizontal axis H at 0°U. Thus, when these non-offset units are illuminated, the range of the light beam is improved outside areas where there is a risk of glare and where the FMVSS 108 standard recommends not lighting above the horizon.
- IIHS Insurance Institute for Highway Safety
- the light module according to the invention offers good visibility while respecting the regulations to avoid the dazzling of a driver coming in front.
- the optical element is adapted to have a single row of light guides composed of eight separate guides.
- an upper row 7 of illumination units Y1 to Y8 shown in dotted lines is located above the row 6 of illumination units X1 to X8. This upper row 7 of illumination units Y1 to Y8 makes it possible to form an adaptive complementary driving beam.
- the optical element can be adapted to include the desired number of guides to form the desired number of illumination units in each of the rows.
