Definitions
- the invention relates to the technical field of lighting and signaling, more particularly for applications in the automotive field.
- Such a light module comprises, conventionally, a collector with a reflective surface of revolution with an elliptical profile, in the shape of a cap in a half-space delimited by a horizontal plane.
- An essentially point light source, of the electroluminescence diode type is located at a first focus of the reflecting surface and illuminates in the half-space towards said surface. The rays are thus reflected in a convergent manner towards a second focus of the reflecting surface.
- Another reflecting surface generally flat, with a cut-off edge at the second focus ensures upward reflection of rays which do not pass precisely through the second focus, these rays then being refracted by a thick lens towards the bottom of the beam lighting.
- This reflective surface is commonly referred to as a “folder” in that it “folds” rays that would otherwise form an upper portion of the lighting beam toward the top of the projection lens.
- Such a light module has the disadvantage of requiring significant precision in the positioning of the folder and the cutting edge.
- the projection lens must be a thick lens due to its short focal length, which increases its weight and complicates its production, such as sink defects.
- the collector has a certain height and, therefore, a certain height requirement.
- the published patent document WO 2020/025171 A1 discloses a light module in particular for a motor vehicle, comprising a collector with a reflective surface collecting and reflecting the light rays emitted by a light source into a light beam, similar to a bending light module.
- the light module also includes an optical projection system, such as a lens, specifically configured to project the light beam in question forming an image of the reflective surface of the collector.
- the optical projection system has a focus located on the reflective surface, for example at a rear edge thereof so as to correctly image said edge and form a clear break in the projected light beam.
- Certain rays emitted by the light source and not reflected by the reflecting surface of the collector can, however, reach the optical projection system and degrade the projected light beam.
- a screen, or blocker placed in front of the light source is provided. The creation of the screen or block, particularly in the context of an industrial implementation, is not covered in this teaching.
- the invention aims to overcome at least one of the disadvantages of the aforementioned state of the art. More specifically, the invention aims to propose an implementation of the screen of the state of the art, which is optically efficient and usable industrially.
- the subject of the invention is a light module comprising a light source capable of emitting light rays; a plate supporting the light source; a collector with a reflective surface configured to collect and reflect light rays into a reflected light beam along an optical axis; an optical system configured to project the reflected light beam by imaging a portion of the reflective surface; a screen located in front of the light source, following a main direction of propagation of the reflected light beam, and configured to collect light rays coming directly from the source, called direct rays; remarkable in that the screen extends in a transverse direction with a constant section and is arranged on the plate.
- direct rays we mean the light rays capable, in the absence of the screen, of directly reaching the entry face of the optical system, or in other words, of reaching the entry face of the optical system without have been previously deflected by an optical element, in particular by the reflective surface. These direct rays, in particular those emitted parallel or almost parallel to the optical axis, would contribute to the projected light beam in the absence of the screen without have been shaped by the collector and the reflecting surface, which is not desirable.
- the collector and the reflecting surface have the shape of a cap or half-shell.
- the reflecting surface has an elliptical or parabolic profile of revolution around an axis parallel to the optical axis.
- the transverse direction is perpendicular to the optical axis.
- the screen has an end face, opposite the plate, which is convex.
- the end face may also be called the end zone.
- This end face, or end zone corresponds to the side of the screen which is opposite the side of the screen facing the plate.
- the end face, or the end zone can be continuous or comprise several faces or portions separated by an edge.
- the end face of the screen has a profile comprising a rounded portion with a radius of curvature greater than or equal to 0.1 mm and/or a straight portion inclined by at least 10° towards the rear and the plate.
- the profile in question is transverse to the main direction of the screen, corresponding to the transverse direction, meaning that the profile is in a longitudinal plane parallel to the optical axis.
- the screen has a rear face collecting direct rays located at a distance d, along the optical axis, from the light source which is less than or equal to 10mm, preferably less than or equal to 4mm .
- the distance is measured between a front edge of the light source and a rear edge of the rear face of the screen.
- the rear face of the screen is part of the end face of the screen.
- all or part of the rear face of the screen may form part of the end face of the screen. At least part of the rear face then forms a portion of the end face.
- Said part of the rear face forming a portion of the end face can form a continuous face with the rest of the end face of the screen, that is to say that said part of the rear face does not is not separated from the rest of the end face by an edge.
- said part of the rear face forming a portion of the end face of the screen can be separated from the rest of the end face of the screen by an edge.
- the end face can then comprise one or more edges separating different faces or portions.
- the section of the screen is triangular, circular, oval or pentagonal.
- the screen is made of metallic material.
- the screen is fixed to the plate by welding, brazing and/or bonding.
- the screen does not have any surface treatment of the reflective type and/or the light-absorbing type.
- the measures of the invention are advantageous in that they make it possible to place the screen close to the light source, which makes it possible to dimension the screen with a reduced size, in particular a height, thus avoiding intercepting objects. rays of the reflected light beam, and also to extend the plate forward beyond the screen and to extend to the same extent a radiator for cooling the light source, under the plate, that is to say -say on a face opposite to that supporting the light source.
- the measures of the invention are also advantageous from an industrialization point of view, in that the screens can be cut from a bar having the desired section and in that they allow the screens to be positioned and fixed as desired. on different turntable models.
- FIG 1 is a schematic representation, in side view, of a light module according to a first embodiment of the invention
- FIG 2 is a schematic representation, seen from above, of the light module of Figure 1;
- FIG 3 is a side view and perspective illustration of the light source, the screen and the collector of the light module of the first embodiment of the invention
- FIG 4 is an illustration in side view and perspective of the light source, the screen and the collector of a light module according to a second embodiment of the invention
- FIG 5 is an illustration in side view and perspective of the light source, the screen and the collector of a light module according to a third embodiment of the invention.
- front and rear refer to a main direction of propagation of rays along the optical axis.
- Figures 1 to 3 illustrate a light module according to a first embodiment of the invention.
- Figure 1 is a schematic side view of the light module 2.
- the light module 2 comprises, essentially, a light source 4, a plate 6 supporting the light source 4, a collector 8 capable of reflecting the light rays emitted by the light source 4 to form a light beam reflected along an optical axis 10 of the module , and a projection lens 12 of said beam.
- Other optical projection systems than the projection lens are possible, such as one or more mirrors.
- the light source 4 is advantageously of the semiconductor type, such as in particular an electroluminescence diode.
- the light source 4 emits light rays in a half-space delimited by the main plane of said source, in a main direction perpendicular to said plane and to the optical axis 10.
- the collector 8 comprises a main body 8.1 in the form of a shell or cap, and a reflective surface 8.2 on the interior face of the main body 8.1.
- the reflective surface 8.2 can advantageously have a profile of the elliptical or parabolic type. It is advantageously a surface of revolution around an axis parallel to the optical axis. Alternatively, it may be a free form surface. It can also include several sectors.
- the collector 8 in the form of a shell or cap is advantageously made in materials with good heat resistance, for example glass or synthetic polymers such as polycarbonate (PC) or polyether imide (PEI).
- parabolic type generally applies to reflectors whose surface has a single focus, that is to say a zone of convergence of light rays such as the light rays emitted by a light source placed at the level of this convergence zone are projected at a long distance after reflection on the surface. Projected at a long distance means that these light rays do not converge on an area located at least 10 times the dimensions of the reflector. In other words, the reflected rays do not converge towards a convergence zone or, if they converge, this convergence zone is located at a distance greater than or equal to 10 times the dimensions of the reflector.
- a parabolic type surface may therefore have parabolic portions or not.
- a reflector having such a surface can in particular be used alone to create a light beam.
- the light source 4 is arranged at a focus of the reflective surface 8.2 so that its rays are collected and reflected into a reflected light beam along the optical axis. At least part of these reflected rays have angles of inclination a with respect to said optical axis which are less than or equal to 10°, so as to be in the so-called Gaussian conditions, making it possible to obtain stigmatism, this is i.e. sharpness of the projected image. These are advantageously the rays reflected by the rear part of the reflective surface 8.2.
- the projection lens 12 is advantageously a bi-convex lens, that is to say with a convex entry face 12.1 and a convex exit face 12.2.
- the lens 12 is said to be thin, for example less than 6mm, due to the low inclination of the rays to be deflected.
- the lens 12 has a focus 12.3 which is located, along the optical axis 10, at the level of the light source 4 or even behind said source. In this case the focus 12.3 is located on the reflective surface 8.2 of the collector 8, more precisely at its rear edge, here also lower edge.
- the reflecting surface if it is of the elliptical type, has a second focus located in front of the lens 12 and at a distance from the optical axis 10. It should be noted that it is also possible for this focus to be located at the rear of the lens and/or on the optical axis, preferably close to the lens, so as to reduce the width of the beam at the entrance face of the lens.
- the light module 2 comprises a screen 14 arranged in front of the light source 4 and facing the reflective surface 8.2 of the collector 8, with a rear face 14.2 capable of collecting the direct light rays 16 emitted towards the 'before directly by the source in question 4, that is to say not meeting the reflective surface 8.2.
- a measurement is useful to avoid the presence of parasitic light rays likely to participate in the formation of the light beam without being strictly speaking imaged.
- These direct rays 16, in particular those which are parallel or almost parallel to the optical axis 10, will then potentially illuminate an upper part of the light beam, which is not desirable in the case of a lighting beam cut-off.
- Figure 2 is a schematic view from the top of the light module 2 of Figure 1.
- the screen extends in the transverse direction 14.1 which is preferentially perpendicular to the optical axis 10 and preferably parallel to the plate 6.
- the screen extends in the transverse direction 14.1 so as to intercept or collect the direct light rays likely, in the absence of the screen 14, to reach the entry face 12.1 of the projection lens 12 and to interfere with the projected light beam. This makes it possible to intercept these parasitic rays.
- the screen has a constant section along the transverse direction 14.1. In this case, the section in question is pentagonal, more specifically a regular pentagon. One of the five sides of the pentagon is placed against the plate 6 and two adjacent sides, located at the rear of the screen and adjacent to the side placed against the plate 6, form the rear face 14.2 of the screen 14.
- the screen 14 is advantageously made of metallic and/or plastic material, in particular by extrusion. Its section is advantageously full, that is to say free of hollows or voids of material.
- the rear face 14.2 of the screen 12 is advantageously free from surface treatment of the reflective type and/or the light-absorbing type.
- the part of the direct light rays 16 incident on the rear face 14.2 in question which is reflected, is in reality partly reflected towards the reflecting surface 8.2 of the collector 8 and partly towards the plate.
- the portion of direct light rays 16 reflected towards the plate is then mainly absorbed there.
- the portion of direct light rays 16 reflected towards the reflecting surface 8.2 of the collector 8, is with angles of incidence such that they are then reflected forwards at a distance from the lens 12.
- Figure 3 is a side view and perspective illustration of the light source, the screen and the collector of the light module 2 of Figures 1 and 2.
- the distance d, along the optical axis (not shown but corresponding to a horizontal direction in Figure 3), between the light source 4 and the screen 14, is reduced, preferably less than or also 4mm. This distance is measured between a front edge of the light source 4 and a rear edge of the screen, more precisely a rear edge of the rear face 14.2 of the screen 14. This reduced distance provides an optical advantage in that the screen can thus collect and block direct light rays while not intercepting any of the light rays reflected by the reflective surface 8.2 of the collector 8.
- the end face of the screen 14, also called end zone has a convex profile.
- This comprises in this case a rounded portion 14.3.1 with a radius of curvature and two straight portions 14.3.2 and 14.3.3 inclined at an angle [3 and y, respectively with respect to a direction parallel to the optical axis.
- These two straight portions 14.3.2 and 14.3.3 are on either side of the rounded portion 14.3.1 which is then central.
- the end face 14.3 is thus formed by a continuous surface formed by the rounded portion 14.3.1 and the two straight portions 14.3.2 and 14.3.3.
- the rear right portion 14.3.3 is part of the rear face 14.2.
- the side of the pentagon located at the rear of the screen and not adjacent to the side placed against the plate forms the rear right portion 14.3.3.
- Part of the rear face 14.2 of the screen is therefore part of the end face 14.3 of the screen.
- the rear right portion 14.3.3 is inclined towards the rear and towards the plate (not shown) by the angle y which is advantageously greater than or equal to 10°.
- the right front portion 14.3.2 is inclined towards the front and towards the corner plate [3.
- the radius of curvature advantageously remains greater than or equal to 0.1 mm and/or less than 1 mm. This radius of curvature and the angle y allow the direct light rays incident on said straight rear portions 14.3.3 and rounded portions 14.3.1 to be reflected so as not to reach the projection lens (not shown).
- Figure 4 is an illustration in side view and perspective of the light source, the screen and the collector of a light module according to a second embodiment of the invention.
- the reference numbers of the first embodiment are used to designate the identical or corresponding elements, these numbers being however increased by 100. Reference is also made to the description of these elements in the context of the first embodiment of the invention.
- the light module 102 differs from the light module 2 of the first embodiment only in that the screen 114 has a triangular section and no longer pentagonal.
- the triangular section is preferably an equilateral triangle.
- the distance d, along the optical axis (not shown but corresponding to a horizontal direction in Figure 4), between the light source 104 and the screen 114, is similarly reduced, preferably less than or also 4mm.
- the end face 114.3 of the screen 114 is somewhat different from that of the screen 14 of the first embodiment of the invention, essentially in that the inclinations
- the end face 114.3 is formed by a continuous surface formed by the rounded portion 114.3.1 and the two straight portions 114.3.2 and 114.3.3.
- the rear face 114.2 is formed entirely by the rear right portion 114.3.3. The entire rear face 114.2 of the screen is therefore part of the end face 114.3 of the screen.
- the part of the direct light rays reflected by the rear face 114.2 is entirely reflected towards the collector 8, unlike the first embodiment where a part is reflected towards the plate (not shown).
- Figure 5 is a side view and perspective illustration of the light source, the screen and the collector of a light module according to a third embodiment of the invention.
- the reference numbers of the first embodiment are used to designate the identical or corresponding elements, these numbers being however increased by 200. Reference is also made to the description of these elements in the context of the first embodiment of the invention.
- the light module 202 differs from the light module 2 of the first and second embodiments only in that the screen 214 has a circular section and no longer pentagonal or triangular.
- the circular section is preferably with a constant radius over the entire periphery, it being understood, however, that this section may have a certain ovality, in particular an ellipse shape.
- the distance d, along the optical axis (not shown but corresponding to a horizontal direction in Figure 5), between the light source 204 and the screen 214, is similarly reduced, preferably less than or equal to 4mm.
- the end face 214.3 of the screen 214 is convex. It is different from those of the screens 14 and 114 of the first and second embodiments of the invention, essentially in that this face comprises a single portion which is in this case a rounded portion 214.3.1, that is to say -say does not have any straight portion.
- This rounded portion has a radius of curvature r which can be substantially greater than the radius of curvature r of the rounded portions 14.3.1 and 114.3.1 of the first and second embodiments of the invention.
- the rear face 214.2 is formed entirely by the rounded portion 214.3.1.
- the entire rear face 214.2 of the screen 214 is therefore part of the end face 214.3 of the screen 214.
- part of the direct light rays reflected by the rear face 214.2 is in the direction of the collector 208 and another is in the direction of the plate (not shown).
- the screen can be fixed to the plate by welding, brazing and/or bonding.
- the screen is advantageously made of metallic material, in particular by extrusion. Fixing by brazing and/or welding is particularly suitable in this case.
- the necessary length can be cut from a bar with the desired section, like one of those presented above.
- the total height of the screen, in a direction perpendicular to the optical axis, is advantageously between 0.5 and 5mm.
- the light modules of the invention can be used to form light beams for regulatory lighting of a motor vehicle, such as in particular a horizontal cut-off lighting function, commonly referred to as "code” or “low-beam” in English, or still without interruption, commonly referred to as “road” or “high-beam” in English.
