Definitions

  • the invention relates to a system for fixing a light source on a counterparty of a motor vehicle headlamp.
  • the invention in particular, a fastening system which makes it possible to fix different types of light sources incorporating a discharge lamp.
  • the invention finds applications in the automotive field and, more specifically, in the field of light projection for motor vehicles. It finds, in particular, applications for the fixation of a light source with possibility of interchangeability between light sources of different types.
  • light projection devices for motor vehicles are equipped with light sources which can be of different kinds.
  • front projectors vehicles are equipped with light sources that can be two different types, namely: a first kind with a halogen bulb, and a second kind to discharge bulb.
  • the source luminaire is also equipped with a high voltage module which ensures the power supply of the discharge lamp.
  • lamp D1 and D2 lamp there are currently two types of light sources called lamp D1 and D2 lamp.
  • Each of these light sources, or lamps has a discharge bulb, a bulb foot and a high voltage module.
  • the high voltage module is immovably fixed in the case of a D1 lamp and, conversely, removably in the case of a lamp D2.
  • the high voltage module makes integral part of the lamp.
  • the high module voltage is not built into the lamp; it constitutes a piece independent, removably mounted on the lamp.
  • FIG. Figure shows a light source 1 having a discharge bulb 2, a bulb foot 4 and a high voltage module 3.
  • the bulb 2 is fixed solidarily to module 3 at the foot of the bulb foot 4.
  • a reflector 5 is provided with an orifice 6 for passage at a base 7. By the orifice 6 passes the bulb 2.
  • a body 2a of the bulb 2 is housed inside
  • the bulb foot 4 is located outside the reflector 5.
  • a lamp holder 8 circular cylindrical shape, forms an integral part of the reflector 5.
  • the lamp holder 8 and the reflector 5 together form a single and even coin called counterpart 9 of the projector.
  • the lamp holder 8 has for role of supporting the discharge lamp 2. It also allows centering and orienting the discharge bulb 2 inside the reflector 5.
  • the lamp holder 8 may also be a separable part of the reflector 5.
  • the lamp holder 8 is then not an integral part of the reflector; it is fixed solidly to the reflector at the time of mounting the projector.
  • the door lamp 8 and the reflector form, in this case too, the counterpart of projector.
  • the discharge lamp 2 is surmounted a high voltage module 3, integral with said bulb.
  • This module 3 has a substantially square outer contour with a relatively small footprint compared to a lamp D2 and its module, which will be described later.
  • module 3 is irremovable leads to some disadvantages. Indeed, when a user is eager to change the discharge lamp of a headlamp from his vehicle, for example because that it is failing, it is obliged to change all the bulb and high voltage module. In addition, the change of this whole bulb and high voltage module is relatively difficult because, on the one hand, of the difficulty accessing the D1 lamp and the operations to be performed to remove the faulty set and install the new set and the fact, on the other hand, risks due to the high voltage present in the module. The user is obliged to have the whole thing changed by a professional, which drive, in addition to the cost of all, a cost of labor.
  • FIG. 2 An example of a D2 lamp with its high voltage module is represented in FIG. 2.
  • This FIG. 2 shows a light source 11 including a discharge lamp 12.
  • a high-voltage electrical module 13 is removably attached to the bulb 12 at the location of a foot 14.
  • a reflector 15 is provided at the location of the base 17 with an orifice passage 16 passing the bulb 12.
  • the body 12a of the bulb 12 is housed inside the reflector 15.
  • the bulb foot 14 is located at the outside of the reflector 15.
  • the lamp D2 comprises a lamp holder 18, for example of circular cylindrical shape, which can make integral part of the reflector 15, or be a separate piece, solidary of the reflector 15.
  • the lamp holder 18 and the reflector 15 together form the counterpart 19 of the projector.
  • the bulb has no electronics associated, that is to say that the high voltage module is independent of the bulb.
  • the high voltage module is not part of integral part of the discharge lamp: it is attached to the bulb after the place the bulb in the reflector. It is therefore possible, during assembly and disassembling the projector, disconnecting the high-voltage module from the bulb.
  • This has a certain advantage over the lamp D1.
  • a lamp D2 it is possible, when the bulb is defective, to change only the bulb and keep the original high voltage module.
  • changing a bulb in a D2 lamp is still more delicate than changing the entire bulb and module for a D1 lamp.
  • the user in the difficult place of access that is a projector, the user must first remove the module, and remove the bulb; he must then change the bulb and put the module back on the bulb, with all the risks inherent to the high voltage in the module. The user is therefore obliged to have the bulb changed by a professional.
  • this type of light source discharge lamp connected to a high-voltage module, shall include means which make it possible, on the one hand, to provide electrical continuity and, on the other hand, a shield to prevent leakage of the electromagnetic field.
  • this type of light source because of the generation of a high voltage by the high voltage module, the light projector is subject to many electromagnetic radiation. In order to avoid a dispersion of the electromagnetic radiation inside the vehicle, a shielding the light projection device is necessary. Indeed, electromagnetic radiation can generate many disturbances in the electrical assembly of the vehicle. Several functions of a current motor vehicle being managed by an electronic system, these electromagnetic disturbances can have consequences serious.
  • the object of the invention is precisely to solve the disadvantages of techniques previously exposed by allowing to fix a light bulb on a projector counterpart, with the same fastening system for a D1 lamp only for a D2 lamp.
  • the invention proposes a system for fixing a light source with a discharge bulb adaptable for different types of light sources.
  • This system is particularly suitable for gas-discharge light sources, such as the D1 and D2 lamps, because it ensures continuity electrical and electromagnetic shielding to prevent field leakage electromagnetic into the vehicle.
  • the invention also relates to a motor vehicle, characterized in that it comprises at least one light projection device previous.
  • Figure 1 already described, shows a longitudinal sectional view a conventional vehicle headlamp with a D1 lamp.
  • Figure 2 already described, shows a longitudinal sectional view a conventional vehicle headlamp with a D2 lamp and a module high tension.
  • Figures 3A and 3B each represent a perspective view of the fixation system of the invention, respectively, in the case where the system is unlocked and in case the system is locked, in the case of a D2 lamp.
  • FIG. 4 represents the fastening system of the assembled invention around a light source D2.
  • FIG. 5 represents the fastening system of the assembled invention around a light source D1.
  • Figs. 6A to 6D show side sectional views and sectional views of the fixing system of the invention, in the case where it's unlocked and in the case where it's locked, for a source luminous D1.
  • Figs. 7A to 7D show side sectional views and sectional views of the fixing system of the invention, in the case where it's unlocked and in the case where it's locked, for a source bright D2.
  • the lamps D1 and D2 have shapes very different from each other. They still have some common, standardized.
  • This common part is the bulb foot. Foot bulb is the rear part of the discharge bulb through which this is attached to the high voltage module.
  • This bulb foot is substantially cylindrical, with the same diameter for the D1 and D2 lamps.
  • height between the neck of the bulb foot and the base of the high voltage module can vary between a D1 lamp and a D2 lamp. Indeed, in the case of a D1 lamp, this height is normalized. On the other hand, in the case of a lamp D2, this height depends on the high voltage module used.
  • the invention therefore proposes to use this characteristic common to two lamps. More specifically, it proposes to fix a fastening system a lamp D1 or a lamp D2 around this common part.
  • the fixation system of the invention is therefore intended to be positioned around the bulb foot of a light source D1 or D2. This fastening system allows to hold and lock the discharge bulb with the door lamp, that is to say the upper part of the counterpart of the projector, in the of the bulb foot.
  • FIGS. 3A and 3B This fastening system of the invention is shown in FIGS. 3A and 3B, in perspective views. More specifically, Figure 3A shows the system in an unlocked position and Figure 3B shows the system in its locked position.

  • This system of fastener 20 comprises a rigid ring 21 and a flexible ring 31.
  • the ring flexible 31 is electrically conductive. It is placed inside the ring rigid 21.
  • the rigid ring 21 is movable in rotation.
  • the flexible ring 31 is not mobile in rotation with respect to counterparty 19. However, it has a degree of freedom, which is a radial translation, with respect to the counterpart of the projector. In other words, as we will see later, the flexible ring 31 can move radially toward the bulb foot, under the effect of a pressure exerted by the rigid ring 21.
  • the flexible ring 31 is made of a flexible material and electrically conductive, for example a metallic material. He rocks thus an electric function, at the same time, by internal contact on the counterpart and by contact of the contact tabs on the high module voltage.
  • This flexible ring 31 has a relatively circular shape; more precisely, it has a circular shape when the fastening system is in locked position; it is circular by segment, or sector, when the fastening system is in the unlocked position.
  • the flexible ring has a larger tangential pitch at a point than in a another point, that is to say greater at the end of the segment than at the beginning of segment. This can be done by shearing the ring at the end of the segment, this which puts the end of the segment naturally behind the rest of the segment.
  • One or more of these different tongues can ensure, in addition, a pre-hold role of the lamp on the counterpart, before the lamp lock is achieved. This tongue then allows the lamp is stable on the counterpart, in a position ready to be locked.
  • the contact tabs are thin and long so to come into contact with an electrically conductive part of the lamp.
  • the holding tabs are wider than the contact tabs, in order to prevent any change of position of the lamp in the counterpart, when the system is in the locked position.
  • the tongue of positioning is fine and long so as to break into a dwelling of the lamp.
  • Each tongue has a substantially vertical sidewall 34 and a base 35 substantially horizontal.

  • the opposite side of the base flank is connected to a flange 36 which connects several tabs between them.

  • One of the sectors may also include a tab of positioning.
  • the flank of the contact tongues may have a shape more or less curve, forming at least one arc of a circle, so as to give flexibility to the tabs to allow better contact with the high module voltage.
  • the holding tongues comprise, in addition to a sidewall 34 and a base 35, a holding arm 37 located in the same plane as the base 35, perpendicular to the sidewall 34 and directed towards the bulb foot 14. It is this arm 37 which serves to maintain the foot in the counterpart, when the fastening system is in its locked position.
  • a holding arm 37 located in the same plane as the base 35, perpendicular to the sidewall 34 and directed towards the bulb foot 14. It is this arm 37 which serves to maintain the foot in the counterpart, when the fastening system is in its locked position.
  • several holding tabs for example three, distributed symmetrically on the flexible ring, that is to say around the bulb foot, it ensures a fixed positioning of the bulb foot inside the ring flexible and therefore the counterpart.
  • the positioning tab comprises, in addition to a sidewall 34 and a base 35, a housing arm located in the same plane as the base 35, perpendicular to the sidewall 34 and directed towards the bulb foot 14. This arm of housing is intended to fit into a lamp housing for ensure correct single positioning of the bulb in the counterpart.
  • the tabs for holding and all have a flank 34.
  • This sidewall 34 allows these tongues to ensure, in addition to their respective roles of maintaining and positioning, a role of electrical conduction and shielding electromagnetic as well as the contact tabs.
  • the flank of the retaining tabs has approximately the same shape curve as the contact tabs.
  • these tabs for holding and positioning may not have flanks; in this case, they only provide their initial role, namely the maintenance and positioning of the bulb in the counterparty.
  • the flexible ring can be made by cutting and folding in a metal foil whose type of metal and thickness are chosen according the desired flexibility. Tabs can also be folded with different shapes and sizes depending on their role. In particular, contact tabs may have a curved shape ensuring better electrical contact with the lamp.
  • the flexible ring 31 which has just been described, is installed in a rigid ring 21.
  • the sectors of the flexible ring are placed side by side, so that the tab of maintenance of a sector is next to a contact tongue of another sector.
  • the rigid ring 21 is made of a plastic material or metallic. It has a circular shape, by segment.
  • the ring rigid 21 is formed of several segments, for example three, solidary the each other. Each segment forms an arc, connected to another segment by a setback.
  • the ring rigid 21 has three segments 21a, 21b and 21c. Segment 21a (and respectively 21b and 21c) is separated from segment 21b (and respectively 21c and 21a) by a recess 23a (and respectively 23b and 23c).
  • the recesses have the advantage of facilitating gripping of the ring by the user to rotate it.
  • the rigid ring 21 has first lugs 22a, 22b (called also prominent parts) forming cams.
  • first lugs 22a, 22b (called also prominent parts) forming cams.
  • the rigid ring has as many first lugs as the flexible ring has tabs of maintenance.
  • the rigid ring therefore comprises three first lugs, only two being visible in the figure. These pins are intended, in the locked position, to push the holding tabs towards the foot of bulb.
  • the rigid ring may comprise a second lug, not shown on Figure 3A, forming a cam. This second lug is intended, in position locked, to put the positioning tab in a housing of the lamp to ensure correct positioning of said lamp.
  • the rigid ring is made so that the flexible ring is against the inner face of said ring and blocked, upwards, by the lugs of the ring.
  • the flexible ring can also be blocked, towards the low, by other lugs used to secure the entire fastening system on the counterparty.
  • the rigid ring 21 has the role of ensuring the locking and the unlocking the fastening system by a rotation about an axis XX 'of the system, that is to say by a rotation relative to the flexible ring and by compared to the counterparty.
  • the rigid ring is rotatable while the flexible ring is not rotatable relative to the counterparty.
  • the rigid ring may comprise, on its inner face, a boss in hard points to prevent the ring from returning to position free. This allows to unlock but not to return to position free.
  • the fastening system is in position unlocked.
  • the rigid ring is therefore in the open position with respect to the flexible ring.
  • the retaining tabs 32 of the flexible ring are positioned each close to a recess the rigid ring; the lugs 22 of the rigid ring are placed in front of contact tabs and do not press on any tab.
  • the flexible ring is therefore free from any contact or support with a lamp.
  • the flexible ring By turning the rigid ring, for example at an angle of about 40 °, the flexible ring is supported by the lug at its most off-center level, that is to say at the level of the retaining tab.
