Definitions

  • the invention relates to a luminaire made of at least luminaire housing and transparent or translucent protective trough or protective cover.
  • luminaire housing bulbs and associated electrical or electronic components are arranged.
  • the protective pan or cover is in particular releasably connected to the lamp housing.
  • Such lights can be ceiling lights, suspended lights, pendant lights, pole lights or emergency lights, such an emergency light can be designed as one of the aforementioned lights.
  • Such an emergency light can also be an explosion-proof light.
  • the protective pan or cover in such a luminaire can be made of various transparent or translucent materials such as glass, polycarbonate or other materials.
  • “protective tub” or “protective cover” may also be formed like a glass bulb or the like.
  • the associated electrical or electronic components are, depending on the lamp used, for example, a ballast, a starter, a temperature or pressure measuring device, a fuse or the like.
  • the corresponding protective tub may be detachably connected to the luminaire housing by a number of screws or the like.
  • the protective tub is pivotally mounted on the lamp housing via, for example, a hinge connection and can be closed in a corresponding closed position.
  • the luminous means has a corresponding spectral range for the emitted light.
  • the light emission usually by one or more within the luminaire housing arranged reflectors is determined at least in terms of the intensity distribution.
  • light has an impact on the environment, which, for example, has an effect on the natural activities of animals. This may be due to the fact that certain animals have a higher sensitivity in certain spectral regions of the light and thus may be negatively or positively influenced by light emitting in this spectral region. This can be done, for example, in street lighting, in a lighting of sidewalks or even in a lighting in parks or the like.
  • EP 1 258 675 A2 discloses a luminaire with a shielding device, which influences a corresponding light emission of the luminaire according to the user's request of the luminaire.
  • US Pat. No. 5,716,123 describes a lamp with a fastening device and a pick-up tube.
  • a reflection device may be arranged in the receiving tube. This is, for example, colored and translucent to adjust the lighting according to the wishes of the user.
  • WO 03/085319 A1 discloses a lighting device with exchangeable color filters. These are used, in particular, to cover electrical devices arranged within the lighting device so that they are not visible from the outside.
  • the invention is therefore based on the object in a simple constructive and variable way to allow a limitation of the emitted light both in spectral terms, as well as in terms of space.
  • a spectral limitation of the emitted light is carried out according to the invention by a filter device associated with the protective trough. This fades out a certain or even several specific spectral regions from the light emitted by the luminous means.
  • a spatial restriction of the light can additionally or alternatively be effected by a glare limitation device assigned to the protective tub. This ensures that the light is emitted from the luminaire only in one or more specific areas.
  • filter device and glare limiting device In order to be able to set corresponding filter device and glare limiting device in a simple manner within the lamp, they can be assigned to a tub inside the protective tub. This means that light that is emitted by the light source in the direction of the protective trough is limited spectrally or geometrically in the region of the trough inside. In the simplest case, filter device and / or glare-limiting device are arranged on the inside of the tub. This eliminates an arrangement of separate tools for holding or arranging these facilities.
  • this is a filter foil or coating arranged or applied on the inside of the tub.

  • the glare limiting device may be an opaque film.
  • An opaque coating of the corresponding areas of the tub inside is also conceivable.
  • a coated plastic film can be used, wherein the coating is selected according to the spectral filtering.
  • both the filter device, and the anti-glare device When using both the filter device, and the anti-glare device, they can be arranged in different areas of the protective tub. It is likewise conceivable that the filter device and the glare limitation device are designed to be complementary relative to the protective tub. That is, where the anti-glare device leaves areas of the protective pan free to exit the light, the corresponding filter device can be arranged in these regions.
  • the filter device can be arranged or applied at least in a region of the protective trough uncovered by the anti-dazzle device in the manner described above.
  • the glare limiting device can be arranged between the inside of the tub of the protective tub and the filter device.
  • this only applies to areas in which both glare limiting device and filter device are arranged. That is, those areas in which the filter device overlaps the glare limiting device, the glare limiting device can be used for the arrangement of the filter device.
