Definitions

  • the invention relates to a spotlight according to the preamble of claim 1.
  • a spotlight has become known through the ERCO lighting program (brochure no. 2869010), 1991/92 edition, first cover page outside, page 288, last cover page inside, last cover page outside.
  • the lamp shown in the aforementioned brochure publication has a U-shaped mounting bracket with two bracket legs, at the free ends of which a guide block for each support rod is arranged coaxially with a tilt axis. Each guide block overlaps the support rod assigned to it, leaving an extensive recess. Both support rods are arranged parallel to each other in the plane of the tilt axis and can be tilted together with the two guide blocks. According to the prospectus publication, a main housing part and additional radiator parts are arranged axially displaceably and lockable on the supporting rods between the two supporting rods.
  • the invention has for its object to provide a spotlight that is particularly suitable to accommodate relatively heavy spotlight additional parts without overloading the load-bearing lamp construction parts.
  • this object is achieved in that, in addition to the inclination adjustment in the axial direction, the support rods are accommodated relatively displaceably by the guide blocks, that the main housing part is fixed rigidly and immovably between the two support rods by means of the two housing attachment points, and that each recess on the guide block side is separated from the associated housing Fastening point is traversable in the axial direction of the support rod.
  • the peculiarity of the spotlight luminaire according to the invention is first of all that the main housing part, together with the two support rods, forms a completely rigid, torsionally rigid assembly which does not warp even under extreme asymmetrical weight loads. It is essential, however, that this rigid assembly, in addition to the tilt adjustment, is also axially displaceable on the inside of the bracket legs along the support rods in the tilt axis, ie by means of the tilt adjustment device.
  • the arrangement according to the invention therefore represents, as it were, an axially displaceable balance beam.
  • the rigid assembly formed from the main housing part and supporting rods - together with all radiator elements - Additional parts - be moved and locked in their axial position relative to the stirrup legs so that the center of gravity of the arrangement is either in or immediately adjacent to the tilt axis.
  • a tilt-lock-lockable guide block is arranged coaxially with the tilt axis on the inside at each free end of a bracket leg, which only overlaps the support rods over a circumferential angle of greater than 180 ° with a guide channel, but here one of the housing attachment points between the main housing and the support rods in the axial direction traversable recess. That design according to the invention allows even greater flexibility with regard to the possibility of an axial relative adjustment of the rigid assembly, which is mainly composed of support rods and main housing part.
  • each housing fastening point forms a tab which is rigidly and positively fastened both to the main housing and to the support rods. Such tabs also distance the main housing part from the support rods.
  • an additional weight compensation axial adjustment of additional radiator parts can be done according to the invention by designing the support rods in that the support rods are designed rack-like at least on parts of their axial length and at least over a circumferential angle range for the engagement of an accessory-side pinion.
  • the spotlight 10 has a U-shaped bracket 11 with two bracket legs 12, 13 and a bracket web 14 integrally connecting the latter, which is provided on the top with a releasable fastening unit 15.
  • the fastening unit 15 is used for mounting, for example, on a part of a building or on a support part specially designed for spotlights.
  • the fastening unit 15 can also - in the case of a lighter overall design of the spotlight - be designed as an infeed adapter which engages in a contacting manner in a power take-off rail, not shown.
  • An essential component of the spotlight 10 is a main housing part 16 which is rigidly and immovably fastened to two support rods 18 which are parallel to one another by means of two tabs 17 which are arranged diametrically opposite one another and represent housing fastening points.
  • the main housing part 16 is fixedly and immovably connected to the two support rods 18 via the tabs 17 in such a way that an approximately H-shaped rigid and connection-rigid assembly is formed in its basic shape, which is denoted by A, B and C in FIG. 1 dash-dotted lines is symbolized.
  • Each guide block 19, 20 forms a guide channel 21, which the support rods 18 o overlaps in the present case with a circumferential angle of about 270th This results in each guide block 19, 20 in each case an inwardly open to the main housing part 16 recess 22, which of the tabs 17, which represent the above-described rigid connection between the main housing part 16 and the two support rods 18, along the x in Fig. 1 can be traversed in both axial adjustment directions.
  • a color filter unit 34 is arranged on the left in front of the main housing part 16 by means of two excessively long adjusting sleeves 23, 24.
  • Such an adjusting sleeve 23, which is axially displaceable on the associated support rod, can be provided with a link-like slot 25, which is penetrated by a clamping screw 27 which penetrates the support rod 18 in a threaded hole 26.
  • the other adjusting sleeve 24 can include a pinion that can be actuated by means of a handwheel 28, the gearwheel 29 of which is rotatably mounted in the adjusting sleeve 24 engages in a rack-like configuration 30 on the outside of the support rod 18.
  • a lamp housing 31 and to the right of this a ballast 32 are arranged axially displaceably on the support rods 18 by means of their own adjusting sleeves 33 along the double arrow x.
  • the guide blocks 19, 20 are each assigned a bracket leg 12 or 13 between clamping clamping plates 35, 36, the clamping force of which can be adjusted via central screws 37.
  • the clamping force can be permanently adjusted to achieve a certain inhibition, while the central screw 37 shown on the left in FIG. 3 can be tightened by means of a hand lever (38) in such a way that the tilt adjustment device is blocked.
  • clamping disk 36 engages with a centering hub 42 in a circular axle hole in the leg 12 or 13.
  • a centering pin 40 passes through the clamping disk 36 loosely in a hiding hole 43, the legs 12, 13 loosely in a part-circular slot link 41 and is screwed into a threaded hole in the clamping disk 35.
  • the ends of the slots 41 serve the centering pins 40 as inclination limit stops. Since the clamping disks 36 have a plurality of hiding holes 43, the tilting region of the spotlight can be oriented, for example from horizontal to vertical.
  • the electrical supply of the spotlight 10 is done via separate cable feeds, not shown. Stud bolts 39 serve to releasably lock the guide blocks 19, 20 on the support rods 18.
