Definitions

  • the invention relates to a luminaire, in particular a suspended ceiling lamp or a ceiling luminaire, according to the preamble of claim 1.
  • a luminaire in particular a suspended ceiling lamp or a ceiling luminaire, according to the preamble of claim 1.
  • the lamp is received in a groove of a perforated plate, on which a secondary reflector is arranged, which after the upwardly radiated light after reflected down into the room.
  • the perforated plate is covered with a white foil.
  • the non-uniform deposition of soil in the gutter e.g., insects
  • a light filtering system for brightness equalization comprising a housing with reflectors, a translucent lower screen and a translucent upper screen disposed between a lamp and the lower screen, the upper screen consisting of a translucent plate having an opaque pattern applied thereto, which comprises the Light transmission through this screen selectively prevented to even out the intensity of the transmitted light.
  • This pattern is formed by a metal layer, which at the same time serves as the ground for the lighting device of the lamps and, moreover, reflects light which is not transmitted back into the space above the upper screen.
  • a luminaire having a translucent cover which partially reflects and partially transmits light, and in one embodiment consists of a perforated sheet clad with a translucent fabric having a suitable combination of translucency and reflectivity.
  • the second screen is mounted so that it prevents in use, at least for the area of the immediate vicinity of the lamps that dead insects, dirt particles or the like. Fall from this area on the first screen.
  • the invention is particularly applicable to such lamps having an outwardly facing opening to the lamp area, in particular those which have an upward opening in use or in which the lamp or lamps are not tillschirnt upwards.
  • the second screen at least in the area relevant for the retention effect, has no holes through which insects can fall onto the first screen.
  • the second screen is curved at least in the region between the lamp (s) and the first screen.
  • the second screen has a smooth surface.
  • first and the second screen between them include a space region which is closed in a cross section perpendicular to the longitudinal axis of the lamp or the lamps. This prevents in particular insects from entering the site.
  • the first screen has a perforated plate lined with a diffusely scattering film on the inside.
  • the problem of deterioration of the optical appearance of the lamp by dead insects and the like Is eliminated by surprisingly simple means that they are held by a second screen at a distance from the first screen, so that they no longer on the latter are visible.
  • the second screen is made of a transparent clear film, a greater light transmission can be achieved than with the conventional grid solution, since - unlike steel meshes - it is not necessary to introduce holes in the material to allow light transmission do.
  • Another advantage is that the second screen is easy to clean.
  • a luminaire housing 10 is provided, from which the perforated plate 1, as can be seen from FIG. 1, is suspended via holding elements 11.
  • a secondary reflector (not shown) is provided which reflects the light diffused and distributed in space.
  • the perforated plate 1 part of the light emitted by the lamp 7 is emitted directly downwards.
  • the perforated plate 1 is lined with an opalized special film 13, which reflects in about 50% of the light and transmits the remaining light directly. This film 13 is located directly on the inside of the perforated plate groove 1.
  • a clear, dimensionally stable retaining film 15 between the lamp 7 and the perforated plate 1 is provided.
  • This retaining film 15 is fixed to the edges 17 of the perforated plate, preferably clamped, and spaced in the inner region of the perforated plate channel of both the lamp 7 and the film 13.
  • the film 15 extends at least over the length of the lamp, more generally over that region which corresponds to the light-permeable region of the perforated plate 1.
  • a space portion 19 is formed, which is completed in a section transverse to the longitudinal direction.
  • this space area 19 is closed on all sides, so that no insects can penetrate from the side.
  • this space area may possibly be open at the two end faces or it may be provided in the retaining film 15 small holes through which insects can not fall, for example, with a diameter of less than 1 mm, for example in a range of 0.01 to 1 mm.
  • the retaining film 15 causes insects that reach the area of the lamps 7 and killed, do not fall directly on the film 13 and on the holes of the perforated plate 1, where they can be seen directly, but are retained at a certain distance so that they do not make themselves visually noticeable.
  • a film 15 a low-cost transparent film can be used, which can be easily wipe off.
  • a retaining film 15 a diffusely scattering film can be used.
  • Fig. 3 shows a modification of the embodiment shown in Fig. 2 of the lamp according to the invention with two lamps 7 1 and 7 second Otherwise, the construction corresponds to that of the embodiment of FIG. 2, wherein the same or corresponding elements with the same reference numerals as in Fig. 2 are shown.
