It is based on the two Pins 6 of their base in a corresponding socket 7 of a turntable-like lamp holder 8, so that it extends in the direction of a radius of the lamp holder 8.
  • the latter is designed according to FIG. 2 as an example with a total of six sockets 7 for as many lamps 5, 5 ', 5''..., of which only two diametrically opposite ones are visible in FIG.
  • lamp holders 8 with a different number of sockets 7 or lamps 5 would be conceivable.
  • the design of the lamps 5, 5 ', 5''... is that of a halogen lamp.
  • the lamp holder 8 together with a drive 9, 10 consisting of an electric motor 9 and an attached gear 10, forms an automatic changer mechanism 11.
  • a different type of drive for example a spring mechanism, would also be conceivable.
  • the changer mechanism 11 is mounted on a stationary plate (not shown in FIG. 1) between it and the gear 10, on which the electric motor 9 and the gear 10 are also located are arranged themselves and which is also firmly connected to the holder 12 of the reflector 2.
  • the latter also carries the lens 3 and is pivotally articulated on the signal lamp 1, so that the changer mechanism 11 together with the reflector 2 and lens 3 can be pivoted out of the lamp body 1 for maintenance.
  • the lamp holder 8 is also equipped at both ends with a side window 13 and 14, respectively.
  • the disk 13 facing the transmission 10 is formed with a control ring 15.
  • the latter has six switching stages milled into its free surface (not visible in the drawing), which cooperate with an ON / OFF switch 16 for the electric motor 9 (see FIG. 2) in order to insert a new one into the reflector 2 to be able to position the lamp 5 to be used exactly in the focal point F of the latter.
  • a quickly connectable or detachable coupling 17 is received, with the aid of which the power transmission from the transmission 10 to the lamp holder 8 takes place.
  • a movable plate 18 which can be swung out by 15 to 20 degrees against spring force and which has on its side facing the lamp holder 8 a centering cone 19 aligned with the latter for centered mounting of the lamp holder 8.
  • the lamp holder 8 together with the lamps 5 located therein can be exchanged for a lamp holder 8 equipped with new or different lamps 5.
  • the refitting of the removed lamp holder 8 can then be carried out under quiet conditions, for example in a workshop.
  • the lamp holder 8 together with its two side windows 13, 14 and the control ring 15 consists of e.g. heat-resistant ceramic material, while the electric motor 9, the gear 10 and the lamp holder 8 have maintenance and lubricant-free storage.
  • An electrical supply part 20 for the electric motor 9 is also accommodated in the interior of the signal filament 1. This is protected against thermal effects by thermal insulation and / or by suitable spacing from the lamp 5 which is switched on in each case.
  • an optoelectronic light detector (not shown in the drawing) is provided on or in the vicinity of the electrical supply part 20, which, upon detection of the failure, switches on the electric motor 9 and thus by turning the lamp holder 8 further, the insertion a new lamp 5 causes.
  • the lamp failure monitoring and the initiation of a lamp change could also be carried out in another way, for example by measuring the electrical current flowing through the switched-on lamp 5.
  • a new lamp for example 5 '
  • the light detector stops the electric motor 9 so that the new lamp 5 is positioned and locked exactly in the focal point F. If the new lamp 5 'does not burn, the change process is continued until a functional lamp, for example 5'', is inserted in the reflector 2.
  • the power supply to the positioned lamp 5 is preferably carried out with the aid of a commutator-like system known per se, similar to the power inverter of rotating electrical machines, which is arranged on a circular printed circuit board on the outside of the two side disks 13, 14 of the lamp holder 8. For reasons of space, they are not shown here.
  • the signal lamp 1 can be provided with means for controlling a lamp change by hand from outside the same.
  • the changer mechanism 11 can be actuated via a remote control.
  • a linearly displaceable magazine could finally be used as a lamp holder.
  • the luminous element 21 illustrated in FIG. 3 as an alternative solution example has on its right side with the signal output a known light matrix 22, which can also be referred to as a display matrix.
  • the frame of the light matrix 22 is hinged to the luminous element 21 for maintenance by means of hinges.
  • an optical fiber bundle 23 is indicated on the input side.
  • the light beam is optionally one of four light sources 24, 24 ', 24''... (see also FIG. 4) arranged concentrically opposite one another in pairs with the aid of a rotatable deflecting mirror suitably positioned in the beam path 25 can be aligned and thus coupled into the light guide bundle 23.
  • the light sources 24 are halogen lamps commercially available for fiber-optic applications with a cold light reflector glued on and pluggable connecting cables.
  • the deflecting mirror 25 projects the focal point of the reflector that is switched on in the section of the light guide bundle 23 behind its input surface, so that it can also be referred to as the coupling point of the respective light beam.
  • the deflecting mirror 25 is carried by a mirror holder 26 which is operatively connected to a positioning drive consisting of a geared motor 29, 30.
  • a control collar 27 is provided which, for the purpose of switching on a respective light source 24, the light beam of which is to be reoriented onto the input surface of the light guide bundle 23, with a cam switch 28 and for the precise adjustment of the deflecting mirror 25 with respect to the same light source 24 interacts with a position switch 31.
  • the parts 25 to 31 together form an automatic changer mechanism.
  • the geared motor 29, 30 there is an electric motor 29, for example a synchronous motor, intended.
  • a supply unit (not shown) with simple switching logic is also provided for the electric motor 29.
  • a different type of positioning drive for example a spring mechanism, would also be conceivable.
  • the pre-focused halogen lamps used as light sources 24 are each fastened to a lamp holder 32 with the aid of a spring element (not shown) in such a way that the respective alignment of their light beam can be optimally accomplished by means of the deflecting mirror 25 on the input surface of the light guide bundle 23.
  • an optoelectronic light sensor which is not visible in the drawing, is arranged in the region of the input surface of the light guide bundle 23, which, upon detection of the failure, switches on the electric motor 29 and thus further rotates the deflection mirror 25 and also that Switching on the next following light source 24 ', 24''... causes.
  • the switching on of the new light source is effected by the control ring 27 via the cam switch 28 when the deflecting mirror 25 has reached about 30 angular degrees before the stop position assigned to the next light source 24. If said new light source 24 ', 24''...
  • the position switch 31 stops the electric motor 29, so that the light beam from this light source is directed through the deflecting mirror 25 precisely onto the input surface of the light guide bundle 23. If the newly switched on light source 24 does not work, the changing process is continued by turning the deflection mirror 25 until the latter is in front of a functional light source, for example 24 ′′.
  • a measuring instrument connected to its circuit could also be provided, which triggers the changing process.
  • manually operable means for controlling the changer mechanism 25 to 31 can also be provided on the outer surface of the luminous element 21.
  • the changer mechanism 25 to 31 can be equipped with remote control to initiate the change process from a central control room.
  • mechanical or electrical means for displaying the position number of the switched-on light source 24, 24 ', 24' '... can be arranged on the outer surface of the luminous element 21.
  • a device for remote scanning of said position number is also advantageously provided on the luminous element 21.
  • color filters can expediently be arranged in front of the light sources 24 in the luminous element.
  • the two variants of the changer mechanism described above as an exemplary embodiment enable a simple and automatic replacement of a failed light source in a matter of seconds without the use of a fault service. This means that any light source can continue to operate until the end of its life. A systematic change of the light sources can also be planned in advance and routinely carried out in long maintenance intervals. If the lighting and / or signaling system is operated safely, its maintenance costs remain low.
  • the system described above can still be used in both alternatives to use stronger light sources than normally required in fog or other poor visibility conditions.
  • This can be achieved in a simple manner by using lamps 5 or 24 of different power in conjunction with automatic or controlled change thereof depending on the prevailing external lighting conditions, both by using correspondingly automatically acting control elements and the like.
  • the respective filament 1 or 21 or a remote control from a central control center for example.
  • the present invention can of course also be used in a corresponding adaptation of the entire mechanical and otherwise described system when using the increasingly frequently encountered, hermetically sealed, reflector-sealed halogen lamps.
