Definitions

  • the invention relates to a radiator according to the preamble of claim 1.
  • a radiator is known from US-A-4 799 136.
  • Spotlights of this type are generally used to achieve extensive lighting and also as wallwashers.
  • Known radiators of this type are often of relatively voluminous design and are exposed to considerable heat loads.
  • the object of the invention is to make a radiator of the type mentioned particularly compact and flat while still ensuring asymmetrical radiation without heat dissipation problems.
  • This configuration enables a symmetrical radiator structure in a particularly flat design while at the same time ensuring asymmetrical radiation.
  • the reflector consists of an extruded profile that can be cut to length, which at the same time forms the spotlight housing and can be connected to the support structure in particular in a center-symmetrical manner.
  • the reflector consists of light reflecting Individual elements forming partial surfaces, which are held on the side windows, with a further flat-shaped reflector, preferably made of perforated sheet metal, arranged on the back of the light-reflecting partial surfaces.
  • a combination of directed light with indirect light can be achieved, although the emitter acts in its appearance as a closed reflector.
  • a particularly good ambient light can be generated with such a radiator, with no heat problems arising in the radiator due to the particularly good ventilation.
  • Figure 1 shows schematically the basic structure of a radiator with asymmetrical radiation, the reflector of which forms and forms the rear wall of the radiator housing there is an anodized aluminum profile on the inside, which is differently graded on both sides of the central plane 6.
  • the cooperating with an elongated light source 3 reflector surface 2 consists of reflecting partial surfaces 4 and arranged between them, due to their orientation at least essentially light-dead partial surfaces 5.
  • the inclination of the respective partial surfaces is different and is selected so that the desired asymmetrical radiation characteristic results.
  • the angles between the reflecting partial surfaces 4 and the light-dead partial surfaces 5 on one side of the central plane 6 are smaller than the corresponding angles on the other side of the central plane 6.
  • connecting webs 14 are formed on the rear side thereof, which enable a connection or a screw connection to a support structure 8, which is designed in a bow-shaped manner and preferably has a plurality of cooling ribs 10.
  • This support structure 8, to which the two-sided side windows 7 are also attached, can also be equipped with a double-frame support, but it is also possible to hold the versions on the side windows 7 or the side support brackets 13 belonging to the support structure 8.
  • FIG. 2 shows the bow-like shape of the support structure 8, within which the stepped reflector 1 and the side windows 7 are located.
  • the sockets 12 for the lamp 3 or the socket receiving areas assigned to the double socket carrier 15 are shown schematically, and it can also be seen that the cooling fins 10 are molded directly onto the carrier structure 8.
  • a cover or filter disk 9 is held by means of suitable holding elements, which can be screwed to the mounting brackets 13 by means of knurled screws 11.
  • a coupling cone sleeve 16 is provided on the support structure 8, which can be connected to an integral connection head part 17.
  • the coupling cone sleeve 16 is pushed onto the complementarily designed connection head part 17 and fixed via a bayonet connection. Due to this design of the coupling cone sleeve 16, it is possible to couple the radiator to support structures, such as are described, for example, in DE-A1 39 16 308.
  • the side windows 7 can be fixed to the support brackets 13 so that a small gap remains between these side windows and the reflector 1, which leads to the formation of an optically attractively shaped light band and also promotes ventilation and thus cooling of the radiator.
  • Figure 3 shows an advantageous embodiment of the invention, which makes it possible to combine directed light with indirect light.
  • lamella-like reflecting partial surfaces 4 have different inclinations, so that asymmetrical radiation is achieved.
  • a relatively wide reflective lamella 4 is provided in the area to the right of the central plane 6, but does not extend to the central plane 6.
  • two narrower, but preferably also differently reflecting slats 4 are arranged, which form a more acute angle with the longitudinal central plane 6 than the wide slat located on the other side.
  • a flat reflector 18 which consists of a perforated plate and forms the rear wall of the radiator, is arranged at a distance from these slats. This flat reflector 18 is fixed to rods 19 which extend between the side windows 7.
  • the beam characteristic can be influenced in a simple manner on the one hand, and on the other hand it can be specified in this way which proportion of light is emitted via the back of the spotlight in the form of indirect light.
  • This embodiment of an emitter or emitter head is preferably equipped with so-called energy-saving lamps.
  • a mount carrier 20 is provided on the side of a side window 7, which is preferably combined with the coupling cone sleeve 16, optionally via additional mechanical connecting parts, to form a unit which can be fixed to a side window 7.
  • a plug part 21 which is preferably held by latching elements and which is provided with guide elements 22 and preferably with a holding element for the cover or filter disc 9.
  • This plug-in part 21 can be easily removed after unlocking, whereupon it is possible to remove the cover or filter disc 9 and to change the lamp in a simple manner.
  • the side windows 7 can be designed as translucent ground glass screens, the mount carrier 20 and plug-in part 21, which are not translucent, at the same time forming masking elements at the points of maximum light intensity.
