Definitions

  • Luminaire with a luminaire housing for holding a lamp, a Shaping element as well as a translucent and elastic Plastic film to cover the lamp.
  • Luminaires are known on the market in various embodiments, e.g. as surface-mounted, recessed and suspended luminaires.
  • the lights are usually with reflectors above equipped with a lamp; to glare are also usually Grid inserted.
  • light band systems are known in which support profiles up to max. 3 lamp lengths to form a formally endless Stringing together of lighting elements composable are. These are suspended from the ceiling or directly to the ceiling fixed support profiles, provide the required longitudinal stiffness ready for bending. They include the electrical Through-wiring and allow by contact elements the Electrification of the lights on the equipment rack - Operating equipment. Either within the stretcher or on the lower end is a device carrier by means of grid fasteners attached, usually as a plate-like sheet profile is formed and on which the electrical equipment attached to the luminaire, for example ballasts, Sockets and cabling. The equipment carrier can thereby within the two U-shaped diverging legs of the Carrying profiles be arranged.
  • Upgrading luminaire covers to luminaires without luminaire covers is not yet possible.
  • For lights with luminaire covers is the structure and geometry of the luminaire cover committed to the acquired embodiment, so a change in the geometric shape and style of appearance the luminaire cover is subsequently not possible.
  • the invention is the Task to avoid this disadvantage at least partially; for luminaires without luminaire cover is the possibility of retrofitting a lamp cover. After all It should be possible, the geometric shape of the lamp cover easy and fast to change.
  • This object is achieved in a luminaire of the above mentioned type achieved in that on the lamp housing a film holder is detachably fastened, that the film holder having a shaping element and that on the film holder arranged a translucent and elastic plastic film is.
  • the film holder forms together with the shaping element and the plastic film a retrofittable and replaceable light cover, which is subsequently attachable to the lamp.
  • the film is translucent and elastic; she has a certain Stiffness, so is self-supporting. It is about in the films used to unshaped, flat and not three-dimensional preformed plastic films.
  • the preferably 0.375 mm thick plastic film are preferably Thermoplastics, for example polymethylmetachrylate (PMMA) or polycarbonate (PC) used; generally w. Because the Plastic film is quite thin, this is also relatively easy.
  • the shaping elements give the non-preformed plastic film a desired cross-sectional geometry.
  • the shaping elements they are usually plate-like Head pieces with a predefined, e.g. triangular cross section, around which the side of the lamp attached Plastic film is stretched so that this plastic film assumes the cross-sectional geometry of the head pieces.
  • the film can also be folded be.
  • the attachment of the film to the film holder can vary over Attachment made.
  • the film holder along the longitudinal axis extending slots with a have certain inclination angle, in which the plastic film is inserted with its longitudinal edges and in the because of their inherent stability and that of the shaping elements caused curvature is maintained.
  • the provision of elastic magnetic tapes the longitudinal edges of the plastic film attached to a corresponding Attachment bar of the film holder can be fastened.
  • the light cover is particularly easy to replace. A slightly firmer fixation can be achieved with Velcro straps.
  • the shaping elements are preferred designed as head pieces. Usually one each Head piece arranged at the head of the lamp and the plastic film spans the entire area between the two Head pieces due to their inherent rigidity without the further Support elements for maintaining the through the head pieces predetermined cross-sectional geometry must be provided. It however, it is also possible, the shaping elements in other areas to arrange the lamp as at the head end.
  • a particularly interesting aspect of the invention is that existing trunking systems are simple and inexpensive Can be retrofitted with a foil cover with variable design are.
  • the film holder directly to existing Fixed grid locks the trunking systems so that no further fasteners or otherwise Conversions are required.
  • Such a grid fastener usually engages behind with its top brackets corresponding locking edges in the support profile and with his Bottom ironing the film holder.
  • the luminaire housing may include light steering systems, such as Example reflectors.
  • Example reflectors In the case of trunking systems, these are half-shell-shaped reflectors usually on the underside attached to the support profile.
  • the film holder on the underside of the device carrier of a lamp or a Lighting system fixable.
  • existing trunking systems can easy, inexpensive and fast through any customizable luminaire covers can be retrofitted.
  • To change the appearance of the lamp cover can do so different head pieces with different cross-sectional geometries be used.
  • the variability of the luminaire cover according to the invention is thereby increasing that the forming elements releasably attached to the film holder are fastened.
  • the designed as a light band system lamp consists essentially from a trough-shaped support profile 10, one at the underside opening of the support profile 10 fixed equipment carrier 20 and one attached to the underside of the device carrier 20 Film holder 30.
  • the retrofit invention Luminaire cover itself consists of the foil holder 30, serving as the shaping elements head pieces 50 and the releasably attachable to the film holder plastic film 60th
  • the tub-shaped support profile is at its upper end with formed on both sides dovetail guides, in which not shown brackets for ceiling mounting latched are.
  • At the lower, open end is as a sheet metal profile trained carrying profile 10 with both sides inside bent-over latching edges 12, 14 equipped.
  • This essentially S-shaped inwardly projecting locking edges 12, 14 indicate their ends horizontally extending locking surfaces on which on both sides of the upper headband 72, 74 a only in cross section rest shown grid closure 70.
  • Equipment carrier 20 At the bottom of the grid fasteners 70 is the equipment carrier 20 alsklippst.
  • the also consisting of a sheet metal profile Equipment carrier 20 covers the opening of the support profile 10.
  • Equipment carrier 20 consists of a flat plate whose longitudinal ends folded upward to a U-shaped cross-sectional geometry to create.
  • offset Sockets 80 At the equipment carrier are arranged offset Sockets 80 for receiving a not shown Fluorescent lamp attached.
  • the device carrier 20 is known in the Way on the lower side mounting bracket 76, 78 of the Snap-on 70 snapped and so on the support profile fixed.
  • the film holder 30 corresponds in Essentially the geometry of the device carrier 20, but something designed to be larger in order to enclose this in the installation position.
  • the film holder 30 is also made of a sheet metal profile, its edges are parallel upwards at a right angle are mutually folded Toedet. This upturned Edges form the contact strips 32, 34 according to the invention of the film holder 30. At these contact strips 32, 34 are the at both longitudinal edges of the plastic film 60 glued flexible Magnetic strips 62, 64 fastened in the installed position. The Magnetic strips 62, 64 are simply applied to the abutment strips 32, 34 placed to the plastic film 60 to the film holder 30th to fix.
  • the Head pieces 50 are triangular in cross section with roundish Longitudinal edges formed.
  • the head pieces 50 can through Headers of other geometry are exchanged to the foil 60 in other geometric shapes to convict. To this end need only the two front-side head pieces 50 of the Slide holder 30 are deducted and replaced by new headers become.
