Definitions
- the present invention relates generally headlamps of the elliptical type for vehicles automobile, and in particular such a projector, designed to generate a driving beam.
- An elliptical type projector includes mainly a recuperator and concentrator mirror ellipsoidal genus, having a first focal region in which a light source is placed, such as the filament of an incandescent lamp or the arc of a discharge lamp, and a second focal region in which forms a spot of light concentration after reflection of the light from the source on the mirror.
- a projector also includes a lens convergent, typically plano-convex, focused at vicinity of the second focal region of the mirror and able to project the light spot onto the road supra.
- Such a projector lends itself well to obtaining a beam delimited by a top cut, such as a passing beam.
- a top cut such as a passing beam.
- a type of headlamp to form a driving beam, i.e. a beam with a peak of concentration in the axis of the road, but also a certain width and a certain thickness.
- a solution to reduce the size of the hole lamp consists in mounting the lamp further back, by relation to the general direction of light emission, so that only its bulb has to pass through the hole lamp, but that the base is located further back. As a result, the lamp hole size can be reduced, even if a safety distance must be respected around the bulb of the lamp to avoid unwanted mirror heating in this region.
- a short distance focal is the direct consequence of a part of a minimization of the lateral and vertical dimensions of the projector, and on the other hand the recoil of the lamp by relation to the mirror, causing the light source to find more back in the mirror.
- This short focal length brings the mirror to generate, by the non-point dimensions of the source (typically a cylinder some 5 mm long and about 1 mm in diameter) a spot of concentration large luminous.
- a solution to overcome this drawback could consist of providing at the front light spot projection a cover similar to those used in dipped headlights but in one position returned, so as to obscure the light illuminating the road too close to the vehicle.
- the present invention aims to overcome these disadvantages and limitations of the state of the art.
- the present invention aims to propose means capable of ensuring a reduction progressive light as this light illuminates areas of the road closer and closer to the vehicle.
- Another object of the invention is to achieve this objective without giving rise to undesirable coloring of light due to the fact that, by nature, a lens deflects radiation differently depending on the length wave of it (phenomenon of chromatism).
- the present invention aims to use a occultation of the light which takes place at a distance from the focal surface of the lens (a plane for a lens perfect - but a kind of dome, including the FL hearth constitutes the apex, for an imperfect lens such than plane-spherical). But at the same time it aims to ensure that, despite such defocusing of the cache, does not witness undesirable coloring phenomena of the beam.
- the present invention provides a projector of the elliptical type for a motor vehicle, comprising a recuperator and concentrator mirror of its kind ellipsoidal having a first focal region in which is placed a light source, and a second focal region in which a spot of light concentration after light reflection from the source on the mirror, and further comprising a converging lens focused in the vicinity of the second focal region of the mirror and capable of projecting on the road said spot of light concentration, the mirror and the lens defining an optical axis of the headlamp, characterized in that it further comprises a cover able to obscure part of the circulating light between the mirror and the lens, arranged as a whole above said second focal region and having at minus two occultation regions spaced in the direction of said optical axis and each capable of obscuring simultaneously a specific part of the light.
- FIG. 2 we have schematically represented a projector which includes in known manner a lamp 10 constituting a source luminous, in this case by its incandescent filament 11.
- This lamp is mounted in a bottom hole 21 of a mirror 20 of the elliptical genus, such as an ellipsoid of revolution.
- the filament 11 is placed in the first focal region F1 of the mirror, so as to form in the second focal region F2 thereof a light spot.
- the projector also includes a lens 30, here a plano-convex lens, whose axis coincides with the major axis of the mirror passing through the first and second focal regions (this axis, designated by x-x, being hereinafter called “the optical axis of the projector”) and whose focus FL is at the level of the second region focal length F2 of the mirror.
- the lens 30 projects infinitely on the road the light spot present in the F2 region, as described above in reference to figure 1.
- this projector is equipped with a specific cover 40 coming to be placed above the plane horizontal passing through the optical axis x-x and having for property of having at least two active edges for selectively obscuring certain components of the light from the mirror (unlike the covers classics used in low beams, which generally extend vertically and which have only one edge - upper - optically active.
- this cache includes an amount 41 possibly having a concealment role but having especially to ensure the mechanical retention of the useful part of the cover on the structure of the projector (for example on an intermediate part of the projector, no described but classic in itself, coming together to fix the mirror and lens).
- the cover 40 can be made in one piece with this piece intermediate.
- the cover 40 also includes a part oblique concealment 42, which extends downwards and towards the rear of the projector, from a front edge 43b, located directly above point F at the same time constituting the second focus F2 of mirror 20 and focus FL of lens, and towards a rear edge 43a ("front” and “Rear” is understood throughout the description in relation to the general direction of issue defined by the optical axis x-x). We thus observe that the two edges 43a, 43b are spaced along the optical axis.
- the occulting part of the cover is a profile extending in the direction horizontal and transverse to the optical axis x-x, i.e. that the edges 43a, 43b are themselves horizontal and parallel to the optical axis.
- Figure 3 illustrates, by the plots of a set of light rays R, that the two edges 43a, 43b of the concealment part 42 play vis-à-vis the radiation bright two autonomous roles, the rear edge 43a occulting (shadow zone Z0) at one level determined for descending rays while the edge before 43b performs a ZO occultation at one level determined for upward radii.
- This new form of cache has been designed mainly to seek mitigation progressive light. Specifically, knowing that there are a variety of light rays, amounts or descendants, who participate in the formation of light at a given height in the beam, such a mask allows a progressive concealment of the light, acting differently on the rising rays and on the descending rays.
- Figure 4 of the drawings is a graph of which the abscissa indicates the downward slope of the light (0 ° corresponding to the horizon, and the values indicated corresponding to the inclination of the light below the horizon), and whose ordinate indicates the proportion of the light transmitted at the exit of the projector (downstream of the lens 30) depending on the aforementioned inclination, the number 1 indicating that all the light passes and the digit 0 indicating that no light passes.
- edges 43a and 43b which is important, while the shape of the cache between these two edges can be arbitrary as long as it does not act on the occultation profile. So we could for example provide a section cover 42 in arc of a circle, or triangular, or other, provided that this section extends for example above the segment right joining edges 43a, 43b so as not to influence the occultation achieved.
- Figure 5 illustrates a second form of realization of the invention, aimed at reducing the chromatism especially in the region of the bottom of the beam.
- the cover 40 of FIG. 5 has a part generally horizontal blackout 42 extending above of focus F, of which a first edge 43a is located in rear with respect to said hearth and including a second edge 43b is located in front of this same focus.
- Figure 6 shows that the three curves attenuation (in red, in blue and median) are extremely close to each other over any the angular extent of the fuzzy cut, and in particular at neighborhood of 0 °, so that no phenomenon of chromaticism is in practice perceived by the driver in line with the road.
- Figure 7 illustrates a third form of realization of the cache, which differs from that of the Figure 5 mainly in that the cover 42 has a very slight inclination, descending towards the front, with respect to the horizontal plane passing through the optical axis xx.
- Figures 9 and 10 illustrate the mitigation behaviors achieved for different settings of the caches in Figures 5 and 7.
- Figure 11 illustrates a fourth form of production of a mask according to the invention, in which the concealment part 42 is characterized by three edges useful 43a, 43b, 43c.
- the cache present in its together the shape of an asymmetrical "V", with an edge rear high 43a, a low intermediate edge 43b and a top front edge 43c, these edges being interconnected at the species by sections 42a, 42b with sections transverse straight.
- the front edge 43c is located here at plumb with focus F, the whole part blackout 42 extending rearwards from this home.
- the rear edge 43a acts on the radiation which is more tilted downward than the portion 42a
- the front edge 43c acts on the radiation which is more tilted upwards than the portion 42b
- the intermediate edge 43b acts on radiation with an inclination intermediate between these extreme inclinations.
- Figure 14 illustrates a fifth form of realization of the invention, similar to that of the figure 11 but which is distinguished by the fact that the portions 42a, 42b of the concealment part of the cover join not at a sharp edge 43b, but at level of a smooth, curved transition (zone 42c, by example of an arc-shaped section).
- edges 43a, 43c play the same roles than before, but at the edge 43b is substituted an area 42c actually constituting an infinity of edges blackout 43b, variable according to the inclination of the neighboring light.
- the low point of the area 42c constitutes a blackout edge vis-à-vis the radiation which spreads horizontally.
- Figure 15 shows that the attenuation law here looks quite different from that in Figure 12, with attenuation first limited to close proximity to the center line of the road (0 °) then which intensifies as the projected radiation is tilted down.
- this embodiment allows to leave a greater amount of light near near the axis of the road, for good comfort driver's visual.
- the sixth embodiment, illustrated on the figure 17, approaches again that of figure 11 in the sense that the concealment part 42 has three optically active sharp edges, respectively 43a, 43b and 43c.
- the essential difference is that the front edge 43c on the one hand is at a neighboring height that of the intermediate edge 43b above the axis optics x-x, and on the other hand is in front by relative to the position of the focal point F on said axis x-x.
- the objective here is to obtain attenuation curves similar to those in Figures 12 and following, but limiting or avoiding coloring at the same time unwanted beam especially in its region low.
- V reversed portions 42b1, 42b2 which join the edges 43, 43c is here inoperative; it could for example also be a straight line, or a circular arc of concavity down.
- the seventh embodiment illustrated on the Figure 19 is an intermediate embodiment between that of figure 14 (rounded edge) and that of Figure 17 (overall arrangement of the edges). So the blackout portion 42 has a rear edge 43a, a front edge 43c and a curved intermediate region 42c which defines an infinity of blackout edges 43c, according to the inclination of the light which passes in its vicinity (see above).
- Figure 21 illustrates an eighth form of realization of the invention, which is similar in its principle to that of figure 17, with a parameter setting different.
- the attenuation performed is practically zero until about 1 ° below the horizon, to keep more light still in the axis of the road, then then adopts a similar appearance, in an interval angular restricted, to that of figure 18, and this for all wavelengths so that none beam coloring at the start of mitigation is not encountered.
- the ninth embodiment of the invention illustrated in FIG. 23 takes up the principle illustrated in figure 19, a difference essential consisting in the fact that the portion 42b which joins the curved intermediate edge 43b and the edge before 43c is tilted slightly upwards, and more shorter than in the case of Figure 19, and that at the same time the portion 42a is more inclined.
- cover 40 for perform attenuation from values negative tilt (rising light) (especially if the maximum concentration of beam in the absence of cache is not in the axis of the road (0 °), but slightly above it (for example at about 1 ° above).
- the corresponding figures have been indicated scales in millimeters.
- the attenuation curves have been modeled with forms of caches such as precisely illustrated, for an example a lens 30 glass with flat inside face and outside face spherical, with a useful radius of the lens of 72 mm, a 44 mm median draw, a 44.5 mm draw in the red and a 43.5 mm print in blue.
- the different illustrated examples show that it is generally possible to achieve it by simple folding of a thin sheet such as a steel sheet. Any other manufacturing technique and any other material can of course be considered, depending including required precision and resistance to the high temperature prevailing within such projector.
