Definitions

  • the invention relates to a lamp holder for a projector. or fire, especially for a motor vehicle.
  • the invention is particularly applicable to the case projectors located in a location such that it remains in the posterior part of the reflector that a very low clearance for removal and replacement of the projector lamp.
  • This configuration is meets more and more often in vehicles modern, where we very compactly have the different components in the engine compartment.
  • the invention proposes to remedy the difficulty above by providing a headlamp or light as defined in claim 1.
  • Figure 1 is a schematic drawing, seen from rear three-quarter, reflector, bulb holder and lamp according to the invention, showing the way the lamp holder of which is inserted into the reflector and mounted on it.
  • Figure 2 is a sectional elevation, along the broken line II-II of Figure 4, of the lamp holder assembly and lamp placed in the reflector, in the position final assembly.
  • FIG. 3 is a front view of the lamp holder alone, showing the operating arm and the centering means of the lamp.
  • Figure 4 is a rear view of the same lamp holder mounted on the reflector, the solid line drawing corresponding to the final mounting position of the lamp holder and the line drawing corresponding to the insertion position of this lamp holder in the notch of the projector.
  • FIG. 5 is a rear view of the reflector alone, in the region of the central opening, showing in particular the bearing faces receiving the lamp and the lamp holder.
  • FIG 1 there is shown schematically the headlamp configured according to the invention, designated so general by the numerical reference 1.
  • the lamp holder and lamp assembly is intended to be mounted in a central opening 5 formed in the axis of the reflector, for example in the axis of the paraboloid in the most common case of a reflector spotlight parabolic.
  • the lamp holder is introduced by a notch 6 formed from the opening 5 and which extends approximately for example along the intersection of the reflector surface with a vertical or slightly inclined radial plane.
  • a slight inclination ⁇ (figure 4) of the order of 9 °, but without any character limiting.
  • the notch 6 is blind; it extends towards axial towards the front of the projector over a length approximately corresponding to the length of the lamp 4. This dimension actually depends on considerations practical and we will understand that, if we have a slight clearance in the rear part of the reflector, one can foresee a shorter notch in direction axial.
  • the notch 6 allows the insertion of the lamp essentially by a vertical translational movement of descent (arrow 7 in Figure 1) followed, after setting place the assembly at the back of the projector, with a movement rotation (arrow 8) over a fraction of a turn, to lock the lamp holder in place in the opening 5.
  • the lamp holder 3 essentially comprises a body lamp holder 9 receiving the lamp in a itself known (for example by plugging in contacts, as can be seen in the section in Figure 2) and provided at the rear with electrical connection means to the lamp, which can either be a connector plug-in either, as shown at 10 in FIG. 1, lead wires overmolded with the body of the lamp holder and directly from a bundle of cables.
  • the lamp holder 3 has a flange 11 which will further explain the role as well as a rod or arm elongated maneuver 12 allowing the user to perform the rotational movement (of arrow 8) when the lamp holder is placed in the opening 5 of the reflector 2, and this despite the low clearance at the back of the reflector.
  • the collar 11 has an approximately circular shape and flat and comes to slip between, on the one hand, the rear side of reflector 2 at the periphery of the opening 5 and, on the other hand, a retaining part 13 (FIG. 2 and 4) which is preferably a metallic insert attached to the projector at 14 ( Figures 2 and 5) at screw means 15.
  • the retaining piece 13 has surfaces 16 ( Figure 4) holding region 17 of the collar 11 pinch between this surface 16 and the rear face facing the reflector, around the opening 5. This prevents axial movement of the lamp holder, while authorizing its introduction from above then its pivot around the central axis; in other words, the retaining piece 13 acts like a receptacle for the lamp holder, this being guided radially and axially inside this receptacle by the collar.
  • the retaining piece 13 also advantageously comprises elastic blades 18, for example the number of three ( Figure 2 and 4), which come to stress axially a surface facing 19 of the lamp.
  • the disassembly of the lamp is done by the operation exactly opposite: pivoting of the lamp holder up to bring the arm into a substantially vertical position, then lifting it by passing through the reflector to the lamp by the notch 6.

Claims (5)

  1. Scheinwerfer oder Signalleuchte, vor allem für Kraftfahrzeuge, insbesondere ein Scheinwerfer oder eine Signalleuchte, bei dem bzw. der im rückwärtigen Bereich nur ein kleiner Freiraum zum Einsetzen einer Lampe vorhanden ist, wobei der Scheinwerfer oder die Signalleuchte (1) einen Reflektor (2) aufweist, dadurch gekennzeichnet, daß der Reflektor mit einer radialen Aussparung (6) versehen ist, die das Einführen einer Lampe in den Reflektor von außen im wesentlichen durch eine bezüglich des Reflektors radiale Verschiebebewegung (7) ermöglicht, wobei die Einheit aus der Lampe und einem zugehörigen Lampenträger sich axial beiderseits einer mittigen Öffnung (5) des Reflektors teils innerhalb und teils außerhalb des Reflektors erstreckt, und daß der Lampenträger umfaßt:
    ein Lampenträgerelement (9), das zur Aufnahme der Lampe (4) und eines Bauteils (10) zum elektrischen Anschluß an diese geeignet ist,
    einen Bedienhebel (12), der mit diesem Trägerelement verbunden ist und bezüglich der Achse des Reflektors im wesentlichen radial verläuft,
    Mittel zur axialen Zentrierung des Trägerelements am Reflektor,
    Mittel zur Führung des Trägerelements bezüglich des Reflektors von einer Einführungsstellung bis zu einer montierten Stellung, wobei der Übergang von der montierten Stellung in die Einführungsstellung durch eine Drehbewegung (8) des Trägerelements bezüglich des Reflektors um einen Drehwinkel (β) erfolgt und
    Mittel zur Arretierung des Trägerelements am Reflektor in der montierten Stellung.
  2. Scheinwerfer oder Signalleuchte nach Anspruch 1, bei dem bzw. der die Mittel zur axialen Zentrierung Randauflageflächen (22) an der Einheit aus Lampe und Lampenträger umfassen, die mit entsprechenden Anschlagflächen (23) der Reflektoröffnung zusammenwirken.

    bei dem bzw. der die Führungsmittel einen Kragen (11) am Trägerelement aufweisen, der mit einem mit dem Reflektor einstükkig ausgebildeten Halteteil (13) zusammenwirkt, das jegliche axiale Verschiebung verhindert.
  4. Scheinwerfer oder Signalleuchte nach Anspruch 3,
    bei dem bzw. der das Halteteil (13) zudem elastische Zungen (18) umfaßt, die die Einheit aus Lampe und Lampenträger axial gegen den Reflektor drängen.
