Definitions

the present invention relates to lighting projectors in which the lamp, which is provided with a flange, is mounted on a lamp holder comprising a housing for the lamp base, and elastic means bearing on the reflector and acting on the lamp holder are provided to hold the lamp in place by applying the flange to a bearing surface of the reflector provided for this purpose around a central opening of the reflector.
a known solution (FR 2,077,665) consists in housing the lamp holder in a chimney integral with the reflector and in keeping it in place by means of a helical spring compressed between the lamp holder and a part arranged telescopically on the holder. lamp and removably fixed in the fireplace. This solution is relatively complicated, and leads to significant bulk at the rear of the reflector.
the object of the present invention is to provide a lamp holder and means for fixing the lamp holder on the reflector which are very simple and allow the lamp to be replaced quickly and easily.
the headlamp object of the present invention is characterized in that the lamp holder is constituted by a piece of an electrically insulating material which is provided with attached metal elements ensuring electrical contact with the pin or pins of the lamp and possibly with the base or flange of the lamp and the front end of which comprises an annular surface resting on the flange of the lamp, and in that said elastic means consist of one or more elastic fasteners stretched between the reflector and the holder lamp.
At least one of the elements ensuring electrical contact with one of the pins of the lamp will be constituted by an elastic blade, said pin being clamped between one end of the blade and a bearing surface of the lamp holder to ensure a mechanical connection. between the lamp and the lamp holder.
a metal washer can be fixed, for example by gluing, on the front end of the lamp holder and connected to an electrical conductor to ensure an electrical connection between the conductor and the flange of the lamp clamped between the washer and the surface of the reflector on which it is based.
the fixing of the lamp holder on the reflector can be ensured by an elastic bracket articulated on the reflector and overlapping the lamp holder.
a ramp will then be formed on the rear end of the lamp holder to facilitate the installation of the stirrup, this ramp leading to a V-shaped notch in which the transverse part of the stirrup will be housed.
This attachment could also be achieved by means of coil or leaf springs, one end of which is fixed or articulated on the reflector and the other end of which is provided with a claw which hooks onto the rear of the lamp holder.
the reference number 10 designates a reflector which comprises in its central part a cylindrical appendage 12 closed by a disc 14 pierced with an opening 16 for the passage of a lamp 18.
This comprises a flange 20 applied on the disc 14 and provided with one or more pins 22 received in holes drilled in the disc to ensure the correct positioning of the lamp on the reflector.
the base 24 and the single pin 26 of the lamp are placed in a housing provided for this purpose in a lamp holder 28.
This consists of a cylindrical piece of an electrically insulating material which can be manufactured, for example, by molding a plastic material.
a metal washer 30 is fixed, for example by gluing, on the front end, adjacent to the reflector, of the lamp holder. This washer is in contact with the flange 20 of the lamp and provides an electrical connection between the latter and a conductive wire 32 welded to the washer.
a metal blade 34 is fixed, for example by means of a rivet, to the lamp holder. One end of this blade is applied elastically against the pin 26 of the lamp and on its other end is welded a conductive wire 36. The pin 26 is clamped between the blade 34 and a bearing surface of the lamp holder.
the blade 34 therefore plays a double role: it maintains the lamp on the lamp holder and it provides an electrical connection between the pin 26 and the wire 36.
the lamp / lamp holder assembly is held on the reflector by means of an elastic bracket 38, the ends of which are housed in two holes drilled in appendix 12 of the reflector, so as to constitute an articulation whose axis 40 is perpendicular to the axis 42 of the reflector, and the transverse part of which is received in V-shaped notches 44 cut out on the rear end of the lamp holder, the point of the V lying in the plane defined by axes 40 and 42.
the rear end of the lamp holder is profiled in the form of a ramp 46.
the stirrup 38 is dimensioned to exert on the lamp holder a relatively large axial force when it is in the position described above and illustrated in Figure 2.
the flange 20 of the lamp is then tightly clamped between the washer 30 and the disc 14 of the reflector, and the latter, the lamp and the lamp holder constitute a relatively rigid whole.
