  • a lamp head which has a concave mirror reflector and with a battery container for receiving batteries, furthermore with a light source, preferably an incandescent lamp, for generating light.
  • the position of the filament relative to the focal point of the concave mirror reflector cannot be changed, since the incandescent lamp is firmly connected to the concave mirror reflector during operation and can only be removed from the concave mirror reflector to install a new incandescent lamp if the bulb fails.
  • prefocus incandescent lamps are extended by an extremely precise position of their filament relative to the stop edge of their base, so that the luminous element is exactly in its combustion chamber when the prefocus bulb is installed in the concave mirror reflector. This is achieved in that the plate edge of the prefocus base P13, 5s is pressed against a stop of the concave mirror reflector and the luminous element of the prefocus incandescent lamp is exactly at the focal point of the concave mirror reflector.
  • the luminous elements of prefocus lamps are aligned precisely with the plate rim of their base during manufacture, both at the distance from the plate rim and to the axis of the prefocus lamp.
  • the prefocus bulb is installed from behind through a hole in the apex of the concave mirror reflector with the bulb first in a corresponding receptacle or socket of the concave mirror reflector, the bulb of the incandescent lamp with its filament protruding into the concave mirror reflector and the plate rim of the base striking a corresponding stop on the concave mirror reflector .
  • the prefocus lamp is then held by a pressure on the edge of the plate, which is exerted from the base side. This can be done by means of a threaded part or a plug-in part, but the pressure for holding the prefocus bulb against its plate edge is always exerted from the base side, while the side of the plate edge facing the bulb of the prefocus lamp serves as a stop.
  • the light bulb is screwed into the battery container and projects with its bulb into the concave mirror reflector.
  • the lamp head with its concave mirror reflector is generally adjustable in the axial direction with respect to the battery container and thus with respect to the incandescent lamp. Differences in the distance between the filament in the axial direction compared to the battery container and the concave mirror reflector can be compensated for by this adjustability.
  • lateral deviations of the filament from the axis of the incandescent lamp which are relatively common in screw-type filament bulbs, cannot be compensated for, since the filament is not specially perforated with respect to the base.
  • the object of the invention is to rationalize the production of such portable lights by utilizing larger production quantities by producing so-called prefocus lights, as well as lights with concave mirror reflectors that are adjustable relative to the filament of the incandescent lamp, according to one and the same new construction principle according to the invention and only by a small, replaceable one

If the lamp head is then moved relative to the filament of the incandescent lamp, then it finally strikes another stop, specifically when the filament of the incandescent lamp reaches the area of the combustion chamber of the auxiliary reflector. As a result, the otherwise unilluminated center of the light spot is also illuminated with the scattered light. It is not necessary in the luminaire according to the invention to find the two best possible technical settings for parallel high beam or scattered near light, rather these best possible settings are given automatically by the stops according to the invention.

  • the lamp head has a slot-shaped recess 65 which, according to the invention, runs in the axial direction.
  • the lamp head 10 with its lamp end 70, which is designed as a stop 6 has been pressed against an edge 90 of the battery container 30.
  • the filament 54 of the incandescent lamp 14 is in the focus of the main reflector 82 and the lamp emits a parallel beam of light.
  • the guide pin 60 strikes with its lower stop end 8 against the other end 74 of the slot-shaped recess 65 and the filament of the incandescent lamp is then arranged outside the focal point of the main reflector 82 in the combustion chamber of the auxiliary reflector 84 and the lamp emits a conical beam of light.
  • the guide pin either snaps into the hole 66 for the fixed setting of a parallel light beam or into the hole 67 for the fixed setting of a conical light beam.
  • FIG. 16 shows a view of FIG. 15 seen from the front in the axial direction. It can be clearly seen that both the lamp head 10 and the battery container 30 are approximately square. Nevertheless, the lamp head 10 can be adjusted in the axial direction according to the invention.
  • FIG. 17 shows a lamp according to the invention as it was shown in FIGS. 15 and 16, but the lamp head 10 has been made translucent or also transparent.
  • this luminaire according to the invention there are many different possibilities according to the invention. If the guide pin 60 is inserted into the slot-shaped recess 65 which runs approximately parallel to the lamp axis and the lamp head 10 pressed in the direction of the battery container 30, then the end of the lamp head 70 abuts as a stop 6 against a stop 8 of the battery container 8 and a parallel high beam is obtained, since in this position the filament 54 of the bulb 14 is in focus of the main reflector 82 is located.
  • the guide pin 60 strikes at the end of the slot at 74 and the lamp body 54 of the incandescent lamp 14 is, according to the invention, in the region of the combustion chamber of the auxiliary reflector 84. In this position, the lamp emits a conical light beam. Looking towards the left side of the lamp head 10, one then sees a longer slot-shaped recess 65 according to the invention. If the lamp head 10 is pulled off the battery container 30 and then rotated 90 degrees back onto the battery container, the guide pin 60 snaps into the longer one slot-shaped recess 65.
