Definitions

  • the invention relates to a spotlight according to the preamble of claim 1.
  • a spotlight has become known from DE-PS 26 18 310.
  • the main housing of the known spotlight lamp is fastened on the inside between the free stirrup legs of a U-shaped holding bracket so as to be tiltable about a tilt axis.
  • the infeed also takes place via the holding bracket by means of a busbar adapter which is rotatably mounted on its bracket web.
  • the main housing of the known spotlight lamp forms two clamping tabs at two diametrically opposite housing fastening points, which, in addition, accommodate two supporting rods at a parallel distance from one another and also relatively displaceably from the retaining bracket.
  • the support rods of the known spotlight lamp are intended to accommodate additional spotlight parts, such as filters, screens, auxiliary lenses, etc. These spotlight additional parts are axially displaceable and lockable on the support rods.
  • the known spotlight also allows that only one support rod is advanced axially when a single support rod for attaching a spotlight accessory is sufficient.
  • the known spotlight advantageously allows a wide variety of possible variations by means of additional or alternatively usable spotlights.
  • the invention has for its object to provide a spotlight that is particularly suitable to accommodate relatively heavy spotlight accessories without overloading the load-bearing lamp construction parts.
  • this object is achieved in that the main housing part forms a rigidly and non-displaceably attached connecting bridge at the two housing fastening points between the two support rods and in that the two support rods are also axially displaceable and adjustably locked inside on the bracket legs in addition to the inclination adjustment in the inclination axis .
  • 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, torsion-resistant 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 stirrup leg, which only overlaps the support rods over a circumferential angle of greater than 180 ° with a guide channel and 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 permits 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 such a way that the support rods are designed 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 contact-making manner in a current extraction 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 so firmly and immovably connected via the tabs 17 to the two support rods 18 that an approximately H-shaped rigid and connection-rigid assembly is formed in its basic shape, which is designated by A, B and C in Fig. 1 dash-dotted lines are 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 passing through 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 along the double arrow x by means of their own adjusting sleeves 33.
  • 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 so firmly by means of a hand lever (38) 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.
