Definitions

  • the invention relates to lighting and / or signaling devices for motor vehicles.
  • a signal light for a motor vehicle comprising a support, a lamp holder fixed to the support, a lamp fixed to the lamp holder, and a reflector fixed to the support.
  • the configuration of the parts requires that the light be assembled by mounting the reflector on the support, then the lamp holder on the support.
  • the parts arrive on the chain in an order that does not correspond to the above-mentioned assembly order. Assembly is slowed down, which increases the cost price.
  • the manufacture of the reflector is provided by the manufacturer, and that of the support and the lamp holder is provided by a subcontractor, the latter cannot mount the lamp holder on the support before delivery to the manufacturer. It is therefore preferable to have a lighting and / or signaling device enabling the parts to be assembled in an order different from the above order.
  • Document FR-A-2 304 025 describes a lighting device for a motor vehicle, comprising a support, a lamp holder fixed in a housing of the support, a lamp fixed to the lamp holder and a reflector fixed to the support by snap-fastening.
  • the reflector carries snap hooks adapted to penetrate holes in the support in the vicinity of the lamp base to fix the reflector to the support. In order to allow the mounting of the reflector after the fitting of the lamp, these hooks extend radially at a great distance from the base of the lamp. It follows that the reflective surface of the reflector extends backwards at a distance from the bulb of the lamp and radially away from the lamp holder. Consequently, a significant amount of light escapes between the base and the reflector towards the rear of the device. The optical efficiency is therefore low. In addition, the space between the base and the reflector is visible from outside the light, which affects the aesthetics of the vehicle.
  • An object of the invention is to provide a lighting and / or signaling device making it possible to mount the trim element after mounting the lamp on the device, while providing good optical performance and giving a satisfactory aesthetic to the fire.
  • a lighting and / or signaling device according to claim 1 is provided according to the invention.
  • the trim element can be fixed to the support with its surface extending very close to the bulb of the lamp so that most of the rays emitted by the lamp towards the rear are stopped by the trim element.
  • no space is more visible between the lamp and the trim element from outside the vehicle.
  • This device also allows mounting of the trim element on the support after mounting the lamp on it. In addition, it avoids having to give a significant length to the latching members of the trim element (which would complicate the manufacture and the shape of the trim element and would be expensive).
  • the lighting and signaling device for a motor vehicle comprises a headlamp and a signaling light which is here a flashing light.
  • the device comprises a support or housing 2 comprising a flat wall having an opening 3 which constitutes a receiving housing for a lamp holder.
  • the device comprises a lamp holder 4 fixed to the support in the housing 3, for example by means of fixing by quarter-turn locking.
  • the fire comprises a lamp 6 in the form of a circular section bulb having an axis 8 defining the axis of the fire.
  • the lamp is fixed by its base to the lamp holder.
  • the device further comprises a trim element in the form of a reflector or optical surface 10 fixed to the support.
  • the reflector comprises a recess or aperture 12 of axis 8 adjacent to the lamp holder and to the base of the lamp, and extending opposite them.
  • the recess 12 of the reflector has dimensions transverse to the axis 8, one of which L is illustrated in FIG. 1, which are greater than the transverse dimensions of the lamp, that is to say in this case greater at the largest diameter D of the lamp.
  • the support comprises latching members in the form of rigid hooks 14 projecting from the flat wall of the support and each having a lug directed towards the axis 8 and the lamp holder.
  • the reflector comprises latching members in the form of lugs 16 parallel to the axis 8. These lugs 16 are flexible in a direction transverse to the axis in direction of the latter and of the lamp holder, namely towards the interior of the reflector. They each have an orifice adapted to receive one of the lugs.
  • the hooks 14 and the lugs 16 cooperate mutually and respectively for the snap fastening of the reflector to the support, the assembly being carried out by bringing the reflector 10 from the support 2 according to a movement along the axis 8.
  • Each lug has a convex curved face or inclined with respect to the radial direction to the axis 8.
  • This face constitutes a ramp for the tab 16 associated during mounting of the reflector 10 on the support 2, the ramp forcing the tab 16 to bend in the direction of the lamp holder at passage of the lug, as shown in Figure 2.
  • This ramp effect causes the reflector to be centered when it is mounted on the support. This assembly is thus facilitated.
  • the mounting of the reflector is made more difficult by the fact that the operator must himself suitably position the reflector as a function of the orifices of the support intended to receive the pins.
  • the lamp holder 4 has a zone 18 extending opposite the hooks 14 of the support and the lugs 16 of the reflector. In the radial direction of flexion of the legs, namely in a direction perpendicular to the axis 8, this area has a dimension M sufficiently small to allow the flexing of each leg 16 of the reflector when the hook 14 of the support passes.
  • the reflector 10 extends in a radial direction between the hooks 14 of the support and the lamp holder 4. It extends opposite the lamp holder 4 and the wall of the support 2 at a distance from it. this.
  • the assembly of the device comprises the following steps.
  • the lamp 6 is mounted on the lamp holder 4, then the lamp holder 4 on the support 2.
  • the reflector 10 is mounted on the support 2. For this, we pass the lamp 6 in the recess 12, which is made possible by the aforementioned dimensional condition.
  • the reflector 10 is snapped onto the hooks 14 of the support thanks to the flexibility of the lugs 16.
  • the legs 16 of the reflector 10 are rigid and the hooks 14 of the support 2 are flexible in a direction radial to the axis 8 in the opposite direction to the lamp holder 4, namely towards the outside of the reflector 10.
  • the face of the lugs forming a ramp thus causes the hooks 14 to flex when the tabs 16 pass when the reflector 10 is mounted on the support 2.
  • the transverse dimension M of the zone 18 of the lamp holder 4 extending opposite the legs 16 may be greater than in FIG. 1. This dimension may be just less than the transverse dimensions of the recess.
  • the legs may be carried by the support 2 and the hooks by the reflector 10.
  • the device may include several signal lamps 6 attached to the lamp holder 2.
  • the recess may then have an elongated shape.
  • the device may include a trim element different from a reflector. This packing element will be for example a refractive optical plate.
