Definitions

  • the invention relates to a portable lamp, such as a flashlight, flashlight or handheld spotlight, with 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.
  • a portable lamp such as a flashlight, flashlight or handheld spotlight
  • 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.
  • the usual prefocus bulbs are characterized by an extremely precise position of their filament relative to the stop edge of their base, so that when the prefocus bulb is installed in the concave mirror reflector, the filament stands exactly in its combustion chamber. 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 so the luminous element of the prefocus incandescent lamp is precisely in 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 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 lamps, cannot be compensated, since the filament is not specifically aligned with the base.
  • the object of the invention is to provide a portable lamp which is designed such that it combines the advantages of prefocus lamps and lamps with adjustable light bundles.
  • Another object of the invention is to combine the advantages of both types of luminaires to achieve higher sales figures per luminaire type, in order to rationalize production.
  • Another object of the invention is to provide means which make it possible to use such a lamp as a fixed prefocus lamp or as an adjustable lamp if desired.
  • Another object of the invention is to show ways in which such luminaires should be designed in order to be able to manufacture them extremely efficiently and, moreover, they can reliably meet all operational requirements.
  • U.S. Patent No. 4,286,311 already shows a flange base incandescent lamp, which is inserted with the base first in a receptacle, which is then closed by a separate closure piece.
  • GB-A-2,037,416 it is stated that the end wall of a battery container should be mirrored in order to be able to reflect light falling backwards from the incandescent lamp in scattered form in various directions.
  • GB-A-2,037,416 does not use a concave mirror, but a conically countersunk plane mirror.
  • DE-A-1,105,056 specifies some means of how to lock the movement of a lamp head in the focus area.
  • these means are insufficient to meet today's requirements for the ranges of the light bundles of portable lights, since these means cannot be used to achieve sufficient parallelism of these light bundles.
  • the solution to the problems of the invention consists of a portable lamp, for example a flashlight, a flashlight or a hand lamp with an incandescent lamp and a concave mirror flector, which is arranged in a lamp head and a battery container, the light bulb having a stop acting in the axial direction and the filament of the light bulb being at a predetermined, precisely tolerated distance from this stop, for example with a flange base light bulb which has a prefocus flange base P13.5s (miniature Flange Base), the bulb being installed with the base part first in a bulb holder, the lamp head with the concave mirror reflector being adjustable in the axial direction and the battery container having a stop surface against which a stop surface of the lamp head or the concave mirror reflector abuts, in this Position of the luminous body is arranged exactly in the focus area of the concave mirror reflector, and wherein for the axial adjustability of the lamp head of the battery container, a guide pin and the lamp head have a slot-shaped
  • the incandescent lamp holder has a separate closure part which acts on the flange of an incandescent lamp base and the separate closure part is designed as a concave mirror reflector on its side facing the luminous element, the luminous element of the incandescent lamp being arranged in the focus region of the concave mirror reflector.
  • the concave mirror reflector of the separate closure part has deliberate deviations such as curvatures on its reflecting surface facing the luminous element, so that a conical light beam is generated.
  • the battery container has an end wall which faces the lamp head and the bulb holder is formed in one piece with the end wall of the battery container.
  • the bulb holder is formed in one piece with the battery container.
  • the guide pin is formed in one piece with the battery container.
  • the end wall of the battery container has an essentially cylindrical part, against the stop of which the plate edge of a flange base strikes, the part being formed in one piece with the end wall of the battery container.
  • the battery container has an elevation or bead, the edge facing the lamp head being designed as a stop against which the end of the lamp head facing the battery container strikes, the lamp body then being exactly in the focus area of the concave mirror reflector.
  • a protective part is arranged in the battery container, which intercepts the pressure of the batteries on the ground contact of the incandescent lamp, this protective part advantageously being supported on the end wall of the battery container and being fastened to the battery container.
  • the lamp head has a double paraboloid reflector with 2 focus areas, with the lamp in the one stop position of the lamp head being exactly in the focus area of the main reflector, whereas the lamp body in the other stop position is in the focus area of the auxiliary reflector.
  • the slot-shaped recess in the lamp head is extended in such a way that the filament of the incandescent lamp can leave the concave mirror reflector in the region of its hole at the apex.
  • the lamp head consists of a translucent material.
  • the guide part of the lamp head and the guide part of the battery container are non-circular and the lamp head has a slot-shaped recess in its non-circular guide part, which runs parallel to the lamp axis and a guide pin arranged on the non-circular guide part of the battery container engages in this slot-shaped recess, to ensure axial adjustability of the lamp head.
  • the lamp head has a slot-shaped recess and an opening, and when the guide pin snaps into this opening, the filament of the incandescent lamp is arranged precisely in the focus area of the concave mirror reflector.
  • the luminous element has a slot-shaped recess and an opening, but when the guide pin snaps into the opening of the luminous element of the incandescent lamp, it is still arranged outside of the concave mirror reflector, within this concave mirror reflector. This enables the luminaire to generate a conical beam.
  • the lamp head has a slit-shaped recess and an opening, the lamp body of the incandescent lamp being arranged outside the concave mirror reflector but still inside the lamp head when the guide pin snaps into this opening. With a translucent lamp head, light can be emitted to the side in this position.
  • the lamp head has an opening, and when the guide pin snaps into this opening, the filament of the incandescent lamp is arranged precisely in the focus area of the concave mirror reflector. This means that a parallel high beam can be continuously generated during use.
  • the lamp head has an opening, with one Snap the guide pin into the opening of the filament of the incandescent lamp outside the focus area of the concave mirror reflector, but is still arranged within this concave mirror reflector.
  • a conical light beam can be continuously generated for the close range.
  • the lamp head has an opening, wherein when the guide pin snaps into this opening, the filament of the incandescent lamp is arranged outside the concave mirror reflector, but still inside the lamp head.

  • a lamp head (10) contains a concave mirror reflector (12) which has an opening at its apex.
  • an incandescent lamp holder (socket) (34) is arranged on the apex of the concave mirror reflector.
  • the bulb socket (14) of the flange base has been inserted into the concave mirror reflector 12 with its bulb (26) ahead, the side 18 of the plate rim 16 facing the bulb 26 striking a stop 17 of the concave mirror reflector 12, so as to ensure a precise position of the luminous element 54 at the focal point ensure the concave mirror reflector 12.
  • a closure 24 is screwed into the bulb holder (socket) 34 of the concave mirror reflector 12, which presses the flange base bulb 14 with its plate edge 16 against the stop 17.
  • the lamp head 10 is then screwed tightly onto the thread 32 of the battery container 30. It can be clearly seen from this illustration that it is not possible to move the luminous element 54 in the axial direction with respect to the concave mirror reflector 12.
  • FIG. 3 shows a portable lamp, in particular a flashlight, whose lamp head 10 is arranged so that it can be displaced in the axial direction with respect to the battery container 30 with the aid of the oblique slot 64 and the guide pin 60.

  • Figure 7 shows a lamp head 10, which has both an oblique slot 64 and another slot part 68, the slot part 68 is perpendicular to the axis 80 of the lamp head, this ensures that when the guide pin 60 enters this slot part 68, the axial displacement of the lamp head 10 stops relative to the battery container 30.
  • a lamp which is equipped with such a lamp head, can also be used as a prefocus lamp by snapping the guide pin 60 into the hole 66 on the lamp head 10, so that a parallel light beam is always obtained when the portable lamp is switched on.

  • FIG. 10 shows a view of FIG. 9. On this view one can clearly see the three resilient cramps with which the fall protection 96 is fastened to the end wall 31 of the battery container 30. Of course, you can also use a number of other fasteners, for example attach or ultrasonic welding or gluing, without departing from the inventive concept that the bulb protection from the inside rests on the end face 31 of the battery container 30.

This opens the light beam of the main reflector 82, and the dark central area which is thereby formed in the middle is illuminated by the auxiliary reflector 84 and by the concave mirror reflector 56, which is located on the separate closure 24.
  • the slit-shaped recess 64 in this region 92 is designed in such a way that the slit-shaped recess 64 in this region 92 is at a uniform distance from the end 70 of the lamp head 10 having.
  • the guide pin 60 is held between the interfaces 6 and 6.
  • Figure 13 shows the portable lamp of Figures 11 and 12, but here in a further position of the lamp head 10.
  • the lamp head 10 has been moved in this position in the axial direction so far that the guide pin 60 with its stop surface 8 to the stop end 6 of the slit-shaped Cutout 64 strikes.
  • the luminous element 54 of the incandescent lamp 14 is located outside the concave mirror reflector 12, specifically both outside the main reflector 82 and outside of the auxiliary reflector 84. In this position, the light can emerge on all sides through the translucent, for example, transparent lamp head 10 . However, a beam of light remains.
  • the portable lamp can therefore both throw a light beam forwards in the axial direction and emit a warning light or signal light to the sides.
  • Figure 14 shows how the lamp head 10 of Figures 11, 12 and 13 is made on its back. In order to simplify the drawing, it was dispensed with to present this lamp head transparently as in FIGS. 11, 12 and 13. On the back of the lamp head 10 has three holes 66, 67 and 94. You can now take the guide pin 60 out of the slot-shaped recess 64 in the lamp head and turn the lamp head so far that the guide pin snaps into the hole 66.
  • FIG. 15 shows a portable lamp according to the invention with an adjustable lamp head 10, which is of a non-circular design here, for example.

  • 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.
  • Figure 17 shows a lamp according to the invention as it was shown in Figures 15 and 16, but the lamp head 10 has been made translucent or transparent. In addition, you have many different setting options with this lamp. If the guide pin 60 is inserted into the slot-shaped recess 65 running approximately parallel to the lamp axis and the lamp head 10 is 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 one obtains one parallel high beam, since in this position the filament 54 of the bulb 14 is in the focus of the main reflector 82.
  • the guide pin 60 strikes the end of the slot at 74 and the lamp body 54 of the incandescent lamp 14 is located 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 slit-shaped recess 65. If you pull the lamp head 10 off the battery container 30 and then put it back on the battery container rotated by 90 degrees, the guide pin 60 snaps into the longer slit-shaped one Recess 65 a.
