Definitions

  • the present invention relates to a projector device equipped with a connection support for locking lamp.
  • the document EP 1 288 566 describes a projector device according to the preamble of claim 1.
  • the present invention is essentially intended to provide a projector device, a part of which is used as a fixing surface of a connection support.
  • Said connection support is mounted in such a way that it simply guarantees a correct positioning of the electrical connection means (or connector), of a light source comprising counterparts of said electrical connection means in cavities formed in said support: the aim is to ensure a correct and reliable electrical connection between these electrical connection means and their counterparts.
  • dual-mode projectors which combine the functions of dipped headlights and long-range lights: for this purpose, it is possible in particular to have inside the two-mode projector a DFCS type light source (for Double Filament adapted to Complex Surfaces), which comprises two distinct filaments, a first filament being dedicated to a use of the light source as a dipped beam, and a second filament being dedicated to a use of the light source as a light of road.
  • DFCS type light source for Double Filament adapted to Complex Surfaces
  • All of the projectors that have just been mentioned comprise at least one light source and a reflector comprising at least one least one optical system, each optical system being each composed of at least one light source associated with a reflector composed of one or more reflecting surfaces whose arrangement and orientation are defined so as to produce a particular light beam.
  • the operation of fixing the light source on the reflector poses a number of difficulties during the assembly of the projector device, especially since so-called "one touch" fixing operations are now preferred for fixing the light sources DFCS type.
  • the so-called "one touch" fixing operations which can be translated by a simplified fixing operation, are operations which consist in fixing the light source on the reflector in a single operation, decomposable into a translational movement, to introduce the bulb of the light source through a cavity at the top of the reflector, combined with a rotational movement, to effect the locking of the light source on the reflector.
  • the mechanical fastening and the electrical connection may, and preferably must, be simultaneously provided by the simplified fixing operation.
  • connection support present in the invention is involved in the context of these simplified fixing operations. Although these simplified fixing operations are, for the moment, essentially intended for DFCS light sources, the projector device according to the invention is not limited to these light sources only, but relates to all the above-mentioned projector devices, even those not using DFCS light sources, which are likely to resort to the simplified fixing operation mentioned above.
  • the connection support present in the invention can be used in all the projectors devices equipped with light sources whose connection means are arranged radially, whether for example DFCS light sources, or standard lamps of type H8, H9 or H11.
  • the light source 200 essentially comprises a bulb 201, shown in dashed lines, fixed on a support 202.
  • the support 202 is, for its part, constituted by a first cylindrical portion 203, on which the bulb 201 is fixed and a vertex is centered on a lower face of a second cylindrical portion 204, itself terminated by an input means 205 of the light source 200 which allows to manipulate the latter.
  • the second cylindrical portion 204 is wider than the first cylindrical portion 203. It comprises, on its side wall, a set of connecting tabs 206.
  • a set of tabs of The lower face of the second cylindrical portion 204 corresponds, at its periphery left accessible after the junction with the first cylindrical portion 203, to a zone 208 of the support 202.
  • This zone 208 is intended to rest on the reflector 100 when the fixing is effected by means of flexible blades 209.
  • the flexible blades 209 follow the circular shape of the zone 208. They have a first end 210 cut into the thickness of the zone 208, and a second end 211, called the free end, which slightly exceeds the plane defined by the zone 208.
  • the reflector 100 consists of an outer face 101, visible at the figure 1 , and an inner face 102; the reflector 100 having been subjected, at the figure 2 , a section for the purposes of the description, the inner face 102 is visible in this figure.
  • the inner face 102 is also called the optical surface of the reflector: it is it which is responsible for reflecting the light rays emitted by the light source 200 when the latter is fixed on the reflector 100 and the bulb 201 radiates.
  • the reflector 100 has a circular opening 103 formed approximately at its top.
  • the opening 103 is disposed at one end of a termination, or collar, 104 of the reflector 100, said termination 104 being of cylindrical shape.
  • a bearing surface 105 there is a bearing surface 105.
  • the bearing surface 105 has an inner face 106, belonging to the inner face 102 of the reflector 100, and an outer face 107 belonging to the outer face 101 of the reflector 100.
  • the bearing surface 105 has approximately the shape of a ring at the center of which we find the circular opening 103.
  • the circular opening 103 is completed by clearances 108 which are intended to let the locking tabs 207 of the light source 200 into the cylindrical terminal 104.
  • the simplified fixing operation of the light source 200 on the reflector 100 can be broken down into two distinct movements: a first movement, referred to as introduction, consists of a translation along the optical axis of the light source 200 towards the reflector 100 so that the bulb 201 is introduced into the circular opening 103 of the reflector 200.
  • the arrangement of the light source during the insertion movement is such that the locking tabs 207 are arranged facing the clearances 108 which complement the circular opening 103 so that they can also be introduced inside the reflector 100.
  • the flexible blades 209 are in contact with the outer face 107 of the bearing surface 105.
  • the dimensions of the bearing surface 105 and the zone 208 are preferably similar and parallel to each other.
  • the second movement which consists of locking the light source 200 on the reflector 100, can then proceed.
  • the locking step consists of a rotational movement in a plane defined by the bearing surface 105 of the light source 200 with respect to the reflector 100.
  • Various steps of this movement are detailed with reference to the figure 3 .
  • At least one boss 400 is disposed on the outer face 107 of the bearing surface 105.
  • three bosses may be provided, regularly spaced apart on the bearing surface 105.
  • the bosses 400 allow an installer to identify the end of the operation of locking the light source 200 on the reflector 100.
  • the free ends 211 of the flexible blades 209, and more particularly their protrusion 305, are used as a protrusion for locating the bosses.
  • the light source 200 has an inertial effect to complete the locking: indeed, the movement is mechanically accelerated after the passage of the top of the boss 400.
  • the acceleration phase must, d after the standards in force, mark the end of the locking movement. Consequently, the passage of the bosses 400 is carried out simultaneously with the insertion of each connecting tongue 206 into a corresponding holding element 302, each holding element 302 being disposed on the outer face 107 of the bearing surface 105 of the Reflector 100 at a suitable position to receive the connecting tab 206 which is intended for it.
  • the holding elements 302 may for example be clips, that is to say elastic members which, by deformation at the coupling, allow the realization of a mechanical connection, and possibly an electrical connection.
  • each connecting tab 206 is inserted into the clip 302 which is intended for it; simultaneously, at least one locking lug 207, and in particular each locking lug 207, meets a stop 304, disposed at a suitable position on the inner face 106 of the bearing surface 105 so that each locking lug 207 is in contact with a stop 304 disposed on the reflector 100, which is specifically intended for it, when the locking position is reached. Furthermore, when the locking position is reached, the protuberances 305 of the flexible blades 209 bear on the zone 208. Their function is to keep the light source 200 resting on the inner face 106.
  • the bosses 400 provide a non-return effect which blocks the light source 200 in the locking position by preventing a rotational movement in a direction opposite to the locking direction 300 can be carried out without a significant external contribution.
  • Cavities 401 may be provided in zone 208, at each free end 211.
  • free ends 211 supporting protuberances 305 may, if necessary, rise slightly above the level of zone 208 to ensure alignment.
  • the holding elements 302 are not deformed when crossing the bosses, which ensures their sustainable use and, where appropriate, optimum electrical conduction.
  • the following elements - the stops 304, the bosses 400, the clearances 108, the flexible blades 209 and the locking lugs 207 - are distributed in three sets of fasteners, each set of elements comprising one of these elements, said elements being arranged so that they can cooperate to achieve a fastening system operating according to the mechanism just described.
  • the connection tabs 206 are also three in number.
  • connection support for receiving all of the connection tabs 206;
  • the connection support is a single piece in which are provided as many counterparts as there are connection tabs 206 to connect.
  • connection support is made of several parts which are pre-assembled to trap the clips 302 during the final assembly.
  • the connection support is removable: it is disposed on a part of the reflector, in the vicinity of the flange 104, after the molding of said reflector, and can be easily removed later, for example to be replaced by a new connection support comprising a different number of counterparts.
  • connection support is fixed on the reflector on anchor points integrated in the reflector, and the realization of which did not complicate the realization of the reflector, no drawer addition additional requirement was not necessary during the molding / demolding of the reflector.
  • connection support may have different means to ensure that it is arranged in an optimal position to receive the connection tabs ensuring the electrical connection of the light source.
  • Said projector device comprises a removable connection support intended to be fixed on the external face of the reflector, said connection support comprising a set of counterparts of electrical connection means, also referred to as counterpart of connection means, to ensure, in a locked position, an electrical connection with the connection tongues following an operation of locking the light source on the reflector.
