Definitions

  • the present invention relates to a reflector device for a projector fitted to motor vehicles, which ensures a sustainable use of a projector and which allows great maneuverability of the reflectors during their manufacture.
  • Its main purpose is to propose a particular embodiment of a reflector device which makes it possible in particular to ensure good ventilation for a light source which is placed in said reflector device, and which allows manipulation on the production lines which limits the risks of damage to a reflective surface of the reflector device.
  • the reflector device according to the invention can be used indifferently for any of these projectors. It will be more particularly described in the context of so-called elliptical projectors, in which a projection lens is involved, but it could also be integrated into the production of parabolic spotlights, in which no projection lens is used.
  • the different types of projectors all use a light source associated with a reflector.
  • a projector 100 of the elliptical type that is to say involving a projection lens 103, comprises two main parts: a first portion 101 is constituted by the lens 103 and a lens holder 104. A second portion 102 is constituted by a reflective device of the state of the art.
  • the reflector device 102 consists of a single piece filling both the reflector function at a rounded portion 105, and a lamp holder at a rear end 106.
  • the reflector 105 serves to reflect light signals produced by a light source placed in the heart of the rounded portion to produce a light beam satisfying the requirements imposed by different standards.
  • the lamp holder 106 serves to keep the light source in an appropriate position within the reflector 105.
  • the junction between the lamp holder 106 and the reflector 105 is provided by a cylindrical element 107.
  • the cylindrical element 107 is closed: its lateral part has no opening because, to provide openings, the mold used to make the reflector device should involve drawers and would be too complex and expensive to make for the manufacture of this piece; the base (at the level of the lamp holder 106) and the top (at the level of the reflector 105) of the cylindrical element 107 are moreover, at least in large part, closed off by different parts of the light source which is introduced into the reflector 105.
  • the cylindrical element 107 is closed, in particular at its lateral part, poses a first problem: the reflector device 102 is not sufficiently ventilated, and this can adversely affect the long-term operation of the light source when it is is on; indeed, the increase in temperature is very fast in the reflector device 102, which can go as far as the destruction of the light source.
  • FIG. 2 A second problem encountered with the reflector devices of the state of the art is illustrated in Figure 2.
  • a vertical section of the reflector device 102 is shown.
  • An inner surface 201 of the reflector 105 is thus apparent.
  • the cylindrical element comprises in particular an outer wall 202, which was visible in Figure 1, and an inner wall 203.
  • the inner wall 203 also constitutes a closed cylinder.
  • the hooks 204 are obliged to maintain the reflector device 102 at an end 205 of the inner surface 201, which may damage the latter.
  • the internal reflector surfaces are calculated accurately and must subsequently undergo the least possible mechanical stress, and be covered by a varnish surface as homogeneous as possible.
  • the device according to the invention answers the two main problems which have just been exposed.
  • a reflector device is proposed which, on the one hand, ensures good ventilation of a light source placed in the reflector device, and on the other hand facilitates the passage of the reflector device on chains.
  • manufacturing method for coating an inner surface of the reflector with powder is proposed.
  • One of the advantages of the reflector device according to the invention is that it can still be manufactured with molds, without subsequent machining operations of the molded parts that could damage the inner surface of the reflector, the molds used can also always be of simple design, that is to say in particular without the presence of molding drawers.
  • a reflector device in which a reflector element and a lamp element are manufactured separately before being secured.
  • the reflector element thus manufactured comprises a set of supports which are arranged such that a light source subsequently installed in the reflector device can be ventilated satisfactorily.
  • the lamp holder element is secured to the reflector element at the supports by means of centering pins and connecting rods.
  • the invention therefore essentially relates to a reflector device for a motor vehicle headlamp, the reflector device comprising a reflector element comprising an internal reflecting surface, an external surface, and an opening on a rear part of the reflector element to introduce a light source characterized in that the reflector device comprises a lamp holder element secured to the reflector element by means of a set of supports, said supports being arranged so as to create an open space between the lamp holder element and the reflector element.
  • at least one of said supports is supported on a base (311) of the reflector element (301), said base (311) being distinct from the outer surface (309) of the reflector element (301).
  • Another object of the invention is a motor vehicle equipped with a reflector device including one of the features just mentioned.
  • FIG. 3 shows a reflector device 300 according to the invention in vertical section, which is composed in particular of a reflector element 301 and a lamp holder element 302.
  • the lamp holder element 302 and the reflector element 301 comprise respectively a first opening 314 and a second opening 315 (visible in particular in Figure 6) provided to leave a passage for the installation of a light source.
  • a first support member 303, hatched in Figure 3 as it is located in the section plane, and a second support member 304 are visible in this figure.
  • the support elements which will be designated by the term column, are elongated, that is to say they have a length l substantially greater than their height h, which, in a particular example, are respectively of the order 60 millimeters and 15 millimeters; the thickness e of these columns being of the order of 2 millimeters at a first end 307, said fixing end, and of the order of 5 millimeters at a second end 306, said molded end.
  • the reflector device 300 comprises a third column 305, visible in FIG. 5.
  • the third column 305 is not visible in FIG. 3 since it is aligned with the second column 304, that is to say that the planes, called planes supports, containing the surfaces constituting the height of each one of these columns are confused.
  • the first column 303 defines a plane containing a surface constituting its height, said plane being perpendicular to the support planes of the second column 304 and the third column 305.
  • This arrangement of the columns constitutes an excellent polarizer at the time of assembly of the reflector element 301 and the lamp holder element 302, a single assembly position being possible. However, it is possible to carry out otherwise keying during the assembly of the reflector element 301 and the lamp holder element 302.
  • the arrangement of the support columns is such as to reveal an empty space 308 between these columns and between the lamp holder element 302 and the reflector element 301.
  • the cylindrical element 107 of the state of the art has disappeared and has been replaced by a fixing system of the lamp holder element 302 involving support columns.
  • Such openings allow optimal ventilation of a light source introduced into the reflector device 300.
  • the molded end 306 of each column has the shape of an external surface 309 of the reflector element 301, as shown in FIG. 6. This makes it possible to distribute all the pressure forces that could be exerted on the different columns, on a maximum surface of the reflector element, thus limiting the risk of deformation of an inner surface 310, said photometric surface, for reflecting the light signals produced by the light source installed in the reflector device.
  • the molded end 306 of at least one support column terminates at a surface 311 for attaching a lens holder of the type of that shown in FIG.
  • the surface 311 is called the base of the reflective element 301. It does not constitute the back of the reflective inner surface 310. In the illustrated example, this base 311 is disposed in an output plane of the light beam out of the reflector device 301. Such an embodiment makes it possible to further limit the mechanical stresses that could damage the internal surface 310 of the reflector element 301.
  • One or more support columns may further comprise one or more reinforcing elements.
  • Such reinforcing elements are visible hatched in Figure 6: there is seen on the columns 303 and 304 a central reinforcing element 312, located approximately in the center of each column, and an inner reinforcing member 313, located in the vicinity openings 314 and 315 provided for introducing the light source.
  • the reinforcing elements 312 and 313 result in protuberances on the support columns. They serve on the one hand to limit the mechanical stresses that could damage the inner surface 310 of the reflector element 301, and on the other hand to evacuate, by convection a portion of the heat generated by the light source.
  • the lamp holder element 302 is circular in shape, and is capable of receiving in its thickness a ring-shaped element, serving as a base for the light source, which is fixed, for example by a rotational movement, in the lamp holder element.
  • the lamp holder element 302 and the reflector element 301 including the support columns are made in separate molds. This method of Manufacture of the reflector device according to the invention also makes it possible to produce these two elements in different materials.
  • the reflector element 301 and the support columns are made of aluminum, the lamp element being made of a zinc alloy and aluminum. Other metals, alloys or plastics may also be used in the production of these parts, the reflective element may in particular be made of a thermosetting material or a thermoplastic material.
  • each of these ends comprises a positioning pin 316 of a light source which will be disposed in the lamp holder element 302 and a centering and holding rod 317.
  • the positioning pin 316 ensures the correct positioning the light source relative to the inner surface 310 of the reflector element 302.
  • Each centering and holding rod 317 is intended to be introduced into a specific opening of the lamp holder element 302. The presence of the pin is useful so that the clearance between a support column and the lamp holder element is zero or almost zero. Specific openings are also provided in the lamp holder member 302 for receiving each locating pin 316.
  • each centering and holding rod 317 and each positioning pin 316 are introduced into their respective aperture, a peel operation is performed.
  • This operation consists in deforming the end of each centering and holding rod 317, to come and crush it on holding elements 318 provided around each opening intended to receive a holding rod.
  • Such a mechanism for securing the lamp holder element 302 and the reflector element 301 make the combination of these two parts final. A detachment of these two parts would necessarily result in the deterioration of at least one of the elements.
  • Another advantage inherent in the structure of the reflector device according to the invention is that the hooks 204, present on the production lines, can now grip at the openings 308, and thus no longer damage the inner surface 310 of the reflector element 301.
  • the reflector with lamp holder according to the invention is very advantageous, in particular because the studs on which the lamp holder is cup-shaped preferably rest on the front face of the reflector, so there is no (less) deformation of it during assembly.
  • the reflector and the lamp holder are preferably metallic (aluminum or aluminum alloy). This highly conductive material associated with the type of pads already described (“radiator fins”) promotes a satisfactory evacuation of heat.
