Definitions

  • the present invention relates to a focus adjustment of a light source in a housing according to the preamble of patent claim 1.
  • Focusing is already known from FR-A-2 369 500. Focusing is already provided here by shifting the illuminant in the direction of its longitudinal axis. The adjustment is made using a threaded screw.
  • this knob is attached to the FR-A-2 369 500 approximately in the middle of the housing and may be covered by various attachments.
  • the invention is therefore based on the object of developing an adjustment for a lamp of the type mentioned in such a way that, at lower production costs, there is a simpler and more accessible adjustment option for the lamp.
  • the invention is characterized by the technical teaching of claim 1.
  • the lifting drive for the adjustment of the mounting plate is designed as an adjusting lever and / or link guide, which is supported on the mounting plate with at least one eccentric curve.
  • the socket plate shows the socket and the lamp.
  • the actuation of the lifting drive is arranged on the back of the lamp housing, i.e. on the side opposite the illuminant.
  • the adjustment drive for the lifting mechanism is provided from the side of the lamp housing, or that the adjustment drive is carried out from the front, using appropriate tools.
  • the adjustment lever is assigned two different eccentric curves, a lower eccentric curve being supported on the top of the mounting plate, while an upper eccentric curve is supported on the inside of the lamp housing supports.
  • an electromotive adjustment drive in the luminaire housing, which is equipped with a corresponding adjustment element, e.g. a rotatably driven eccentric disc cooperates, which is also designed as a lifting drive for the mounting plate.
  • the mounting plate has approximately the same diameter as the housing and is designed as a heat shield.
  • the mounting plate serves as a heat shield for the area with the electrical connections, lines, etc., in particular also for the handle, so that there is only a relatively low thermal load behind the mounting plate.
  • tabs or guide pins are attached to the mounting plate, which guide the mounting plate relative to the housing.
  • a reflector 5 is held over two front rings 6, 7, the rings 6, 7 attaching a front glass plate 19.
  • a socket plate 2 is adjustably arranged in the adjustment directions (arrow directions 27, 28), the socket plate 2 being connected to a socket 3.
  • the bulb 4 is fastened in the socket 3.
  • the illuminant 4 is designed as a low-voltage halogen lamp; however, other illuminants can also be used, e.g. Incandescent lamps, gas discharge lamps, compact fluorescent lamps and the like.
  • the lamp housing 1 is with a bracket 8 in a manner not shown with e.g. connected to a pipe or the like.
  • an adjusting lever 9 (see also FIG. 5) is adjustable and rotatable.
  • a pivot axis 11 is formed, which is achieved in that the adjusting lever 9 has a head 13 bent out of its plane, which is bent out of the material of the adjusting lever 9 by an approximately C-profiled recess 38. According to FIGS. 1 and 4, this bent head 13 engages in a slot 12 in the lamp housing and accordingly forms the pivot axis 11.
  • the slot 12 here has a C-shaped cross section to prevent the head 13 from falling out towards the front.
  • the adjustment lever 9 has a lower eccentric curve 36 with which it adjusts itself supported on the spring-loaded socket plate 2.
  • the adjusting lever 9 has an upper eccentric curve 37, with which it is supported on the underside of the upper end face of the lamp housing 1.
  • the spring loading of the mounting plate 2 is achieved in that there is a hole in the mounting plate 2 through which a socket screw 14 extends.
  • a spring 15 is arranged in the space between the head 16 of the socket head screw 14 and the underside of the mounting plate 2.
  • the bolt-side end of the shaft screw 14 is screwed into an associated bore 17 in the lamp housing 1.
  • guide tabs 18 are provided which are bent out of the plane of the mounting plate and are preferably arranged on opposite ends of the mounting plate 2, which are guided in corresponding slots which run parallel to the slot 12.
  • the adjusting lever 9 has an upper extension 43 which is connected to a handle 10 which is preferably made of plastic.
  • the adjusting lever 9 is now pivoted via the handle 10 in the region of a slot 21 in the lamp housing 1, then it pivots about its pivot axis 11, the pivot axis 11 simultaneously shifting in the region of the vertically aligned groove 12.
  • the upper eccentric curve 37 is supported on the inside of the lamp housing, while the lower eccentric curve 36 is supported on the upper side of the spring-loaded mounting plate 2. Since, according to FIG. 5, the two eccentric curves 36, 37 have opposite inclinations (are directed in opposite directions), this results in a double one Adjustment path of the mounting plate 2 in the arrow directions 27, 28 in comparison to if only a single eccentric curve 36 or 37 were present.
  • the holder plate 2 is shown in two different positions 2, 2 ', the illuminant 4 being removed and instead the recess 20 for attaching the holder 3 being recognizable.
  • FIG. 5 shows the two opposing and oppositely directed eccentric curves 36, 37 on the adjusting lever 9.
  • the upper eccentric curve 37 has a radius 39 with a center 40 laterally offset from the longitudinal center axis, while the opposite eccentric curve 36 has a center 41 opposite to the former center 40, to which the radius 42 is assigned.
  • FIG. 6 shows a link guide as the adjustment drive, where a link lever 29 is pivotably mounted on the lamp housing 1 in the region of a pivot axis 30.
  • the mounting plate 2 is connected to a pin 32 which engages in the guide 31.
  • FIG. 7 shows, as a further adjustment drive, an eccentric disk 44 which is connected in a rotationally fixed manner to an axis 45 which is rotatably mounted in the side wall of the housing 1. Due to the rotation of the axis 45, the eccentric disc 44 is thus pressed against the top of the spring-loaded mounting plate 2, which is consequently also adjusted in height in the direction of the arrows 27, 28.
  • the mounting plate 2 has approximately the same diameter as the housing 1, the mounting plate 2 also serving as a heat shield.
  • the area behind the mounting plate with the electrical connections, lines, etc., and also the handling or the adjusting lever 9 are not so heavily loaded as would be without a mounting plate 2, in particular with a circular design of the mounting plate 2.
  • the tabs 18 and the guide pins 22 perform the special task that the mounting plate 2 is guided relative to the housing.
  • the tabs 18 and the guide pins 22 are in this case placed parallel to the longitudinal axis of the housing on the mounting plate and run in corresponding guide slots in the housing, so that when the mounting plate 2 is adjusted, it is advantageously guided.
