Definitions

  • the invention relates to a lamp, in particular a suspended ceiling lamp or a recessed ceiling light, according to the preamble of claim 1.
  • a lamp in particular a suspended ceiling lamp or a recessed ceiling light, according to the preamble of claim 1.
  • the lamp is housed in a channel made of a perforated plate, Above which a secondary reflector is arranged, which emits the light emitted upwards reflected down in the room.
  • the perforated plate is backed with a white film.
  • the non-uniform deposit of dirt in the gutter e.g. insects
  • a lamp in particular by a ceiling lamp, with one or more lamps, accessible from the outside in a way are that dirt or insects can enter the area of the lamps, and an at least partially translucent first screen, through which in the state of use the light is emitted downwards, which is characterized by is that in the light path between the first screen and the lamp or the Lamps a second screen made of a translucent material from the first Screen is spaced.
  • the lamp can in particular be a recessed ceiling lamp, a surface-mounted lamp, a pendant lamp or a floor lamp.
  • the second screen is mounted so that it is at least for the Area around the lamps prevents dead insects, Dirt particles or the like fall from this area onto the first screen.
  • the invention can be used in particular in the case of lamps which have an outward-pointing lamp Have opening to the lamp area, especially those that are in use have an upward opening or where the lamp or lamps are not shielded from above.
  • the second screen can be made of a clear material, in particular a clear, preferably dimensionally stable film exist.
  • a clear material in particular a clear, preferably dimensionally stable film exist.
  • the distance between the first ensures Umbrella and the second umbrella are already different from the second umbrella Do not, or at least not sharply, show any retained particles on the first screen.
  • the second screen at least is partially scattering, in particular diffusely scattering.
  • the second screen essentially by a preferably dimensionally stable Foil are formed.
  • the material for the second screen can be used as the material for the second screen another suitable material may also be provided instead of a film.
  • the second screen has at least one for the restraining effect relevant area no holes through which insects fall on the first screen can.
  • the second screen at least in the area between the lamp or lamps and the first screen is curved.
  • the second screen has a smooth surface having.
  • Next bin can be provided according to the invention that the second screen substantially extends over the same width as the first screen.
  • first and the second screen between enclose a spatial area that is perpendicular to the longitudinal axis in a cross section the lamp or lamps is complete. This is particularly an intrusion avoided from the side by insects.
  • the first screen has a a diffusely scattering film on the inside lined perforated plate.
  • the perforated plate can form a groove, from which the lamp or lamps are at least partially enclosed.
  • the problem is solved with surprisingly simple means the deterioration in the visual appearance of the lamp due to dead insects and the like.
  • removing them by a second screen at a distance are held by the first screen so that they are no longer visible on the latter are.
  • This can, especially if the second screen is made of a transparent clear Film, there is greater light transmission than with the conventional grating solution can be achieved because - unlike steel grids - holes are not required into the material to make light transmission possible.
  • a Another advantage is that the second screen is easy to clean.
  • FIGS. 1 and 2 of the lamp according to the invention has a trough-shaped perforated plate 1, which on both ends an end wall 3 is completed, the perforated plate 1 partially with side plates 4 embraces.
  • lamp holders 5 are held between which the lamp 7 extends substantially self-supporting in the groove 1, from which is largely enclosed. Brackets can also be between the end walls 3 9 for electronic accessories, such as starters or the like.
  • the gutter 1 is open at the top, so that above the lamp 7 is essentially over the Entire length of the lamp 7 extending light exit opening is formed, via the Light is emitted upwards.
  • There is a luminaire housing above this light exit opening 10 provided, of which the perforated plate 1, as shown in Fig.
  • This retaining film 15 is on the Edges 17 of the perforated plate attached, preferably clamped, and in the interior the perforated plate channel spaced both from the lamp 7 and from the film 13.
  • the film 15 extends at least over the length of the lamp, more generally about that area which is the translucent area of the perforated plate 1 corresponds.
  • a space is thus between the film 15 and the film 13 19 formed, which is completed in a section transverse to the longitudinal direction.
  • this room area 19 is closed on all sides, so that no insects from the side either can penetrate.
  • this area of space may be on the two faces be open or 15 small holes can be provided in the retaining film, through which insects cannot fall, e.g. with a diameter of less than 1 mm, approximately in a range of 0.01 to 1 mm.
  • the retaining film 15 causes insects to get into the area of the lamps 7 and killed, not directly on the film 13 or on the holes in the perforated plate 1 fall where they can be seen immediately, but at some distance be held back so that they are not visually noticeable.
  • slide 15 an inexpensive transparent film can be used that wipes easily leaves.
  • a scattering, preferably a diffuse, can also be used as the retaining film 15 scattering foil can be used.
  • FIG. 3 shows a modification of the embodiment of the lamp according to the invention with two lamps 7 1 and 7 2 shown in FIG. 2 . Otherwise, the construction corresponds to that of the exemplary embodiment in FIG. 2, the same or corresponding elements being shown with the same reference symbols as in FIG. 2.
