Definitions

  • the invention relates to a reflector screen luminaire with a hood-shaped, opaque upper housing part and a lower housing part that can be at least partially covered by the latter and forms a translucent lamp body.
  • Such a lamp is known from practice.
  • the light source can be replaced; attaching another lower housing part is not possible.
  • the known luminaire thus always has the same lower housing part, so that the shape of the luminaire and the lighting field generated by the luminaire cannot be changed.
  • the invention has for its object to provide a reflector lamp of the type mentioned, the outer shape and the lighting field is variable.
  • the design of the upper housing part as a dome and as a truncated cone-shaped screen part enables the mounting and attachment of differently shaped luminaire bodies. With the help of the bowl-shaped or at least partially hemispherical lamp body, it is possible to change the external shape of the lamp as well as to change the lighting field generated by the lamp.
  • the holding device ensures a detachable connection between the respective lamp body and the upper housing part.
  • the holding device forms an annular support edge for the outer edge of the bowl-shaped lamp body.
  • the support edge is clamped on the inside of the screen part in the area of the lower height level.
  • the circumferential lower height step serves, in the sense of a double effect, on the one hand to positively influence the overall optical impression of the lamp, and on the other hand to detachably attach the bowl-shaped lamp body to the upper housing part with the aid of an annular support edge supported on the height step.
  • the holding device consists of a screw thread formed at the upper end of the at least partially hemispherical lamp body and a counter screw thread provided in the area of the dome.
  • Such threads in a lamp body made of glass, for example, are standardized and widely used in practice. This means that a luminaire body designed in this way can be replaced quickly and easily even by untrained personnel.
  • the lower height step has a circumferential, frustoconical inner wall, the lower diameter of which is smaller than the upper diameter.
  • the lamp body is a bowl-shaped, curved glass, the upper diameter of which corresponds approximately to the diameter of the lower height of the shade part.
  • the lamp body is a cylindrical glass with a hemispherical lower end.
  • the distance of the lowermost point of one lamp body from the lower edge of the screen part corresponds to the distance of the lowermost point of the other lamp body from the lower edge of the screen part. This creates an overall impression of both embodiments of the lamp body.
  • the diameter of the at least partially hemispherical lamp body in the region of the lower edge of the shade part corresponds to approximately a quarter of the lower diameter of the shade part.
  • the lower edge of the shade part thus not insignificantly protrudes beyond the lamp body, so that it is well protected, for example against weather influences such as hailstorms, and can at least be destroyed less easily from above.
  • An annular bead is advantageously provided in the region of the cylindrical part of the upper housing part, the outer diameter of which corresponds approximately to the outer diameter of the upper height step of the shield part.
  • Such a ring bead optically tapers the dome of the upper housing part and can also serve to support the holding device for the lamp body.
  • a reflector lamp 1 according to the invention has a hood-shaped, preferably opaque, upper housing part 2 and a lower housing part 4, which can be covered by the latter and forms a translucent lamp body 3.
  • the upper housing part 2 has a dome 5 with an upper horizontal section 6, to which, in FIG. 1, a truncated cone-shaped connecting piece 7 is connected, which is screwed onto a threaded rod 10. As a result, the dome 5 is releasably attached to the threaded rod 10.
  • the dome 5 has an approximately spherical part 11 and a cylindrical part 12 adjoining it downwards. Approximately in the transition region between the spherical part 11 and the cylindrical part 12 of the dome 5, an annular bead 13 is provided, the outer diameter of which is larger than the diameter of the cylindrical part 12 is.
  • the cylindrical part 12 merges with the formation of a radially outwardly extending upper height step 14 into an approximately frustoconical shield part 15 which is divided into two height sections 20, 21 in the area of its lower opening 16 by a lower height step 17.
  • the outer diameter of the annular bead 13 corresponds approximately to the outer diameter of the upper height step 14 of the screen part 15.
  • the height sections 20, 21 of the screen part are curved slightly inwards, so that the inclination angle, not shown, of each height section 20, 21 to the vertical Longitudinal axis 22 increases from the upper end of each height section to the lower end.
  • 1 and 2 protrudes in the form of a shell or partially hemispherical structure from the lower height level 17 or the lower opening 16 of the screen part 15 and is on the upper housing part 2 by means of a partially in Fig. 3rd holding device 23 releasably attached.
  • the embodiments in FIGS. 1 and 2 differ only in the shape of the lamp body, which according to FIG.
  • the lamp body 24 according to FIG. 2 is a cylindrical glass with a hemispherical lower end 25.
  • FIGS. 1 and 2 differ in the holding device supporting the respective lamp body on the upper housing part 2.
  • this forms an annular support edge 26 partially shown in FIG. 3 for the outer edge of the bowl-shaped lamp body 3, which is not shown, the support edge 26 being clamped on the inside 27 of the shade part 15 in the region of the lower height step 17.
  • This attachment is ensured by the fact that the support edge 26 is made of a resilient material such as e.g. Spring steel exists, and that the lower height step 17 has a circumferential, frustoconical inner wall 30, the lower diameter for clamping the support edge 26 is less than the upper diameter.
  • the lamp body 3 is releasably attached to the support edge 26 by means of known spring clips (not shown).
  • the support edge 26 is omitted in the case of the embodiment according to FIG. 2, since the holding device here consists of a screw thread formed at the upper end of the lamp body 24 and a counter screw thread (not shown) provided in the area of the dome 5. In this embodiment, a casting can be provided in the dome, on which the counter screw thread is formed.
  • the screw thread provided at the upper end of the lamp body 24 is standardized, so that a replacement is also possible the lamp body 24 is easily possible.
  • the distance between the lowermost point 31 of the lamp body 3 and the lower edge 32 of the screen part 15 corresponds approximately to the distance between the lowermost point 33 of the lamp body 24 and the lower edge 32 of the screen part.
  • the diameter of the lamp body 24 in the area of this edge 32 of the shade part 15 is about a quarter of the lower diameter of the shade part. It can also be seen from FIG. 3 that the lower edge of the screen part 15 is rolled up, for example in order to reduce the risk of injury to the mostly sharp-edged material.
  • the latter is released from the support edge 26 in that the outer edge of the lamp body is detached from the spring clips (not shown) with which it is held on the support edge. Then the support edge clamped in the area of the lower level 17 is unhooked.
  • the support edge consisting of a resilient material is briefly deformed so that the outer, bent edge of the support edge 26 can slide over the lower edge of the inner wall 30 of the lower height step 17.
  • the lamp body 24 consisting of a cylindrical glass with a hemispherical lower end is inserted through the lower opening 16 of the screen part 15 until the upper end of the lamp body provided with a screw thread can be screwed into the counter screw thread provided in the area of the dome 5.
  • the support edge 26 for the installation of the Luminaire body 24 unnecessary.
  • the support edge 26 it is also possible to provide the support edge 26 in both embodiments of the lamp body on the screen part 15 if the support edge has a central bore, the inside diameter of which is at least slightly larger than the outside diameter of the cylindrical glass of the lamp body 24.
  • the lamp body is 24 through the central opening in the support edge 26 is particularly well secured against radial movement relative to the upper housing part 2, since the lamp body can be supported on the central opening of the support edge, for example in the event of strong wind loads.
  • the lamp body 3 is installed in the reverse order.
  • the reflector screen luminaire according to the invention enables the luminaire body to be exchanged in an uncomplicated manner, so that the lighting field of the luminaire can be changed in addition to the overall optical impression.
