Definitions
- the present invention relates to the field of automotive vehicle lighting devices. More particularly, the present invention relates to an optical part arranged so as to operate in total internal reflection and designed so as to form a cut-off beam.
- a passing beam or more generally of a beam with a cut-off line delimiting an illuminated area of a dark area where vehicles being followed or coming in the opposite direction may be found
- these surfaces of reflection are arranged to form the beam as well as its cutoff line.
- a reflecting surface can form a collector concentrating the rays towards a cut-off edge formed by an edge separating two other surfaces.
- An optical system is then arranged to image the cut edge. The latter will then form the cut-off line in the beam.
- the surface downstream and below the cut-off edge is arranged vertically, or in other words the cut-off edge is formed by a sharp angle. In this case, no ray which passes next to the cut-off edge meets the first reflection surface downstream of the cut-off edge. It follows that due to this angle, the imaging optical system must extend notably below the level of the cut-off edge so that the imaging system recovers these rays.
- An object of the present invention is to improve the optical parts intended to operate in total internal reflection and designed so as to form a cut-off beam, in particular by reducing the risk of dazzling, in particular without excessively increasing the height of these.
- a first object of the invention relates to an optical part
- the guide portion comprising:
- the entry diopter and the deflection surface being arranged so that the deflection surface reflects light rays from the entry diopter towards the line of foci;
- these rays comprise first rays which pass next to the cut-off edge and reach said first reflection surface, the latter being arranged so as to reflect these first rays towards said second reflection surface so as to produce a terminal total internal reflection on this said second reflection surface, these first rays being reflected towards the exit diopter by this terminal total internal reflection.
- the optical part according to the invention decreases, or even eliminates, the risk of dazzling.
- the light device according to the invention can optionally have one or more of the following characteristics:
- the first reflection surface comprises at least one facet arranged so as to reflect towards said second reflection surface said first rays so as to produce said terminal total internal reflection; this simplifies the design of the first reflection surface by managing some of the rays by a facet, since it is the arrangement of the slope of the latter that allows the corresponding rays to be returned in this way;
- the first reflection surface comprises one or more prisms, called first prisms, the first prisms each having a reflection slope on which the corresponding rays are reflected, the or each facet being formed by the or one of the reflection slopes; it's a simple way to form a facet;
- the reflection slopes are less and less steep as they move away from the cut-off edge towards the output diopter;
- the pitch between the first prisms is constant; this allows to have a surface of connection between two prisms generally of the same height and to avoid variations in thickness which may generate greater injection constraints in the plastics industry;
- the pitch between the first prisms is approximately 1 mm; this small step makes it possible to further discretize and better control the total reflections;
- the second reflection surface comprises at least one facet arranged so as to reflect towards the output diopter some of these rays reflected by the first reflection surface; this or these facets are prisms, called second prisms;
- the length of the first reflection surface from the cutoff line towards the output diopter is greater than twice, preferably four times, the height of the output diopter; thanks to the arrangement of the first surface, it is possible to obtain such ratios without increasing the risk of glare, thus making it possible to have elongated and thin optical parts;
- the height of the exit diopter is less than or equal to 6 mm;
- the optical part comprises several of these said guide portions
- the optical part comprises a plate, the downstream edge of which carries the output diopters of the guide portions, the plate comprising the guide portions arranged directly or indirectly adjacent; we thus have a thin optical part with regard to its depth, namely with regard to the distance between the output diopters and the corresponding input diopters;
- the guide portions can be arranged indirectly in pairs via an optically inactive junction portion; in other words, the junction portion does not receive rays circulating in these guide portions.
- Another object of the invention is a vehicle lighting device comprising an optical part according to the invention.
- This light device can in particular be a vehicle headlight.
- the vehicle lighting device according to the invention can comprise:
- the luminous device being arranged so that the rays emitted by the light source come out of the output diopter to participate in the production of a lighting beam with cut-off, in particular with flat cut-off.
- this lighting beam may be a lighting beam on the sides, also called the “cornering” function (for "in the corners” in English).
- Another object of the invention is a vehicle comprising a vehicle light device according to the invention.
- the terms “rear”, “front”, “lower”, “upper”, “top”, “bottom”, “right”, “horizontal”, as well as their variations in gender or number refer to the direction of light emission outside the optical part.
- the terms “upstream” and “downstream” refer to the direction of propagation of light.
- Figure 1 shows a top view of the optical part according to an exemplary embodiment of the invention
- FIG. 2 represents a perspective view of FIG. 1, seen from above;
- Figure 3 shows a rear view of Figure 1;
- Figure 4 shows a perspective view of Figure 1, seen from below;
- Figure 5 shows a sectional and perspective view along the plane AA ’in Figure 1;
- Figure 6 shows the section corresponding to the section of figure
- FIG. 7 represents a beam obtained with an optical part similar to that of FIG. 1 but with a first plane reflection surface; [0027] [Fig. 8] FIG. 8 represents a beam obtained with the optical part illustrated in FIG. 1.
- Figures 1 to 5 illustrate an exemplary embodiment of an optical part 1 according to the invention.
- the X, Y, Z axes correspond to the respectively longitudinal, transverse and vertical directions of a vehicle in which the optical part 1 is intended to be mounted.
- the optical part 1 is therefore oriented relative to these axes X, Y, Z according to the orientation that it is intended to have in this vehicle.
- the optical part 1 is intended to perform a lighting function in the sides.
- the front and rear of the optical part 1 are therefore generally diagonal relative to the longitudinal axis X and the transverse axis Y, the optical axis O of the optical part being oriented here in a direction close to a bisector formed between the longitudinal axis X and the transverse axis Y.
- the optical part 1 allows the device to lighting that includes it to light on the sides and diagonally, here between the left and the front of the vehicle.
- this optical part 1 can include a plurality of guide portions 10 of the light. These guide portions 10 together form the optical part 1 integrally. In particular, these guide portions 10 may be integrally formed with the whole of the optical part 1.
- the guide portions 10 can be arranged side by side, in particular as here as a fan. This widens the overall lighting beam formed by the optical part 1 when coupled with light sources.
- These guide portions 10 may, as here, be interconnected by a portion of the optical part, called the junction portion 30, forming the continuity of material between two adjacent guide portions 10.
- the cuts and sections of Figures 5 and 6 are made at one of these guide portions 10, namely the fourth guide portion starting from the right of the optical part 1 (namely in FIG. 1, the fourth from the bottom).
- the references in the drawings are essentially placed on this fourth guide portion 10.
- Figure 6 illustrates schematically the path of the rays h, G2 in the optical part 1, more precisely here in one of the guide portions 10, as well as the various total internal reflection surfaces 4, 5 , 1 1, 21 (or TIR, for "Total Internai Reflection” in English).
- the optical part 1 is arranged so as to guide the rays h, G2 between an entry diopter 2 of these rays and an exit diopter 9 of the same guide portion.
- this arrangement is such that very little, or even no radius, passes through the junction portions 30.
- the output diopter 9 extends between a first reflection surface 1 1 and a second reflection surface 21. As here, these two reflection surfaces 1 1, 21 can extend essentially horizontally, the output diopter 9 extending from bottom to top.
- the first reflection surface 1 1 and the second reflection surface 21 here form the front portion of an upper portion of the guide portion 10. This front portion extends between the output diopter 9 and another surface of total internal reflection, i.e. the return surface 4.
- each guide portion 10 comprises a lower portion, extending downward between the input diopter 2 and the return surface 4.
- this lower portion forms an input collimator 3.
- the optical part 1 can comprise on each side means for fixing to a vehicle lighting device.
- the optical part 1 includes two. These are two fixing ears 32, 33, formed integrally with the rest of the optical part 1.
- the optical part 1 comprises portions forming rear tabs 31, allowing vertical positioning, namely in the Z direction, of the optical part 1.
- referencing pins 34, 35 in particular of different shapes, can be provided to ensure a more precise position of the optical part 1 in the lighting device.
- the lower surface comprises a cut edge 6, formed by an edge separating the first reflection surface 1 1 from another reflection surface total internal 5, which forms a folder 5.
- the first reflection surface 1 1 extends downstream of the cut edge 6, from the cut edge 6 and towards, here up to, the output diopter 9.
- the folder 5 extends upstream of the cut-off edge 6, from the cut-off edge 6 and towards, here as far as the collimator 3.
- the second reflection surface 21 can be connected to the return surface 4 by other surfaces.
- the length L of the first reflection surface 1 1 of the cut-off edge 6 towards the output diopter 9 is greater than four times the height h of the output diopter 9.
- the height h of the output diopter 9 can be as here less than 6 millimeters (mm).
- each upper portion present is formed by the first reflection surface 1 1 and the folding machine 5.
- the length of the first reflection surface 1 1 of the guide portions 10 is here about 25 mm .
- Figure 6 is a longitudinal section, namely according to the maximum dimension along which extends the guide portion 10 considered and illustrated. This figure makes it possible to illustrate the operation of each guide portion 10.
- the input diopter 2 is arranged so as to receive almost all, or even all of the rays emitted by the light source 40.
- the collimator 3 concentrates these p rays, G2, towards the return surface 4. Thanks to its arrangement with the input diopter 2, this return surface 4 returns the light rays p, G2 coming from the input diopter 2 towards the cut-off edge 6.
- the output diopter 9 can, as here, form a projection member, arranged so as to image the cut-off edge 6.
- the output diopter 9 may have a curvature arranged so that this output diopter 9 forms a converging system having a line of foci. This focus line is arranged so as to overlap with the cut-off edge 6.
- rays returned by the return surface 4 can be defined: the first rays n, the second rays G2 and the third rays (not shown).
- each guide portion 10 can be arranged so that the spokes passing through the cutting edge 6 directly reach the output diopter 9. These are said second spokes .
- This cut-off edge 6 being superimposed on the line of foci, these second rays G2 then emerge parallel to the direction of the optical axis of the corresponding guide portion 10, axis oriented horizontally according to this illustrated example.
- the third spokes may meet the folder 5 slightly upstream of the cut edge 6.
- the folder 5 is oriented such that it returns these third rays towards the second reflection surface 21, which thanks to its arrangement, sends them back to the output diopter 9.
- These third rays will thus pass above the cut-off edge 6 and therefore the line of foci, so that the diopter output 9 refracts them down.
- the second rays G2 form the upper limit of the beam, the third rays being directed below this limit. It follows that the output diopter 9 projects from these rays a beam having a cutoff line formed by this upper limit, which corresponds to the shape of the cutoff edge 6.
- the first reflection surface 1 1 comprises an arrangement from the cut-off edge 6, here in the form of prisms 13, to prevent the first rays n passing alongside, here above, the cut-off edge 6 go, after total internal reflection on the first reflection surface 1 1, directly on the output diopter 9.
- first prisms 13 are formed by an alternation of ribs and ridges oriented generally perpendicular to the optical axis of the corresponding guide portion 10.
- Each first prism 13 thus comprises a slope or reflection facet 14 oriented upstream and a junction facet 15 oriented downstream.
- reflection facets 14 which are arranged so as to allow the first reflection surface 1 1 to deflect the first rays n by total internal reflection on these reflection facets 14. By this deviation, the reflection facets 14 send these first rays n onto the second reflection surface 21 at an angle making it possible to produce a total internal reflection on this said second reflection surface 21. These first rays n are then reflected towards the output diopter 9 after this reflection on this said second reflection surface 21. This reflection is thus called the terminal total internal reflection.
- the slopes of the reflection facets 14 are less and less steep as they move away from the cut-off edge 6 towards the output diopter 9.
- the first rays n are in fact more and more grazing at their point of. impact on the first reflection surface 1 1 is away from the cut-off edge 6.
- first prisms 13 are arranged up to the output diopter 9.
- the first reflection surface 1 it is possible to have them only on an upstream portion of the first reflection surface 1 1, for example on the first 12 to 15 millimeters and / or at least on the first third of the first reflection surface 1 1.
- the pitch between the first prisms 13 is here constant. This simplifies the
- optical part design 1 and potentially avoids variations in part thickness.
- the pitch between the first prisms can be around 1mm.
- the second reflection surface 21 is smooth. However, alternatively, it could also include a plurality of prisms, called second prisms, the reflection facets of which would be arranged so as to reflect towards the output diopter 9 the first rays n reflected by the first reflection surface 11.
- These second prisms can have the same characteristics as the first prisms 13, in particular concerning their pitch and / or the slope of their reflection facets 14.
- each of the guide portions 10 is able to form a beam having a higher cutoff.
- the sum of all these beams forms the overall lighting beam F in the sides, illustrated in FIG. 8.
- this global beam F has a cut-off line C arranged on the horizon H.
- the isolux curves illustrated represent parasitic rays but which are in a sufficiently small quantity so as not to dazzle.
- the beam F 'of FIG. 7 is obtained. If the latter also has a horizontal cut-off line C', there are, on the other hand, more parasitic rays above the cut line C '. The risk of glare is higher.
- first prisms 13 make it possible to reinject certain rays, namely the first rays n, under the cut-off line C and thus confer a vertical thickness of the beam F greater than that of the beam F 'obtained without the prisms. first 13.
- the invention can be applied to other types of cut-off beams, such as a fog beam, or a passing beam.
