Definitions

  • the invention relates to a method for producing a luminaire grid, which is composed of optically shaped reflector elements and is specifically assigned to a light source, in particular an elongated fluorescent lamp, and a luminaire grid produced by the method.
  • Luminaire grids serve as a cover for the light exit surface and as glare protection, particularly in the case of linear luminaires, and are known in a number of embodiments.
  • a grid light is described in DE-GM 69 23 876, which has interchangeable, matched to the lamp arrangement mirror grid with different light distribution.
  • the mirror louvres are composed of two or more longitudinal webs adapted to the lamps and a large number of thin transverse lamellae, so that there is good luminaire efficiency with sufficient glare limitation.
  • assembling them requires a considerable amount of manual effort and involves the risk of damaging the reflecting surface.
  • Louver grids which are only arranged flat below the lamp on the light exit surface.
  • These one-piece small grids have only low light-directing properties and are not specifically assigned to the lamp, but only serve to glare. Luminaires with such a small grid therefore have a very poor efficiency.
  • the invention is based on the object of demonstrating a method for producing luminaire grids in order to be able to produce and add them largely automatically with comparable optical properties to the high-quality mirror grids mentioned at the outset.
  • FIG. 1 shows in simplified form a lamp housing (1) with a rod-shaped light source, preferably a fluorescent lamp (2), above which a head mirror (3) is arranged as a roof reflector.
  • a luminaire grid (4) can be inserted into the luminaire housing, which is open on its underside (1a), which is provided with optically shaped reflecting surfaces and the manufacture of which forms the core of the invention. After insertion into the luminaire housing (1), the luminaire grid (4) is approximately flush with the underside of the luminaire housing and thus represents the light exit surface of the luminaire, which is usually located approximately at the ceiling level.
  • Each luminaire grid (4) is composed of a plurality of grid chambers (5) of the same type, which are connected to one another via a holding device, preferably a support plate (6).
  • the thin-walled, approximately truncated pyramid-shaped grid chambers (5) (Fig. 1, Fig. 2, Fig. 4, Fig. 5, Fig. 8) or parabolic grid chambers (5 ') (Fig. 3, Fig. 6, Fig. 7 ) are included with their almost rectangular or round, each smooth-surface end contour (5a) or (5'a) on the support plate (6) or, (6 ').
  • the support plate is provided with adapted cutouts (6a) or (6'a), the edges of which are expediently slightly edged upwards.
  • the raised edges (6b) engage in the grid chambers and center them on their end contours.
  • the support plate itself is adapted to the lamp and can be handled by a corresponding edge formation (6c) and by the web-shaped edges (6b) for itself and like a conventional grid.
  • the individual grid chambers can also be designed with other basic shapes, for example oval or elliptical. They are manufactured as individual components by pulling or pressing, preferably from aluminum sheet, which is then anodized. The same applies to the manufacture of the support plate. A high-quality reflective surface and a corresponding optical quality of the luminaire grid are achieved.
  • the grid chambers in turn reach into the area of the fluorescent lamp (2) and enclose it largely due to existing recesses (5b) or (5'b).
  • grid chambers with a rectangular end contour the shape of which matches that of the conventional grids with side mirrors and concavely curved cross blades, result in a high-quality optical system with targeted light control, excellent efficiency and good glare control for interior lights.
  • grid chambers In addition to the sheet metal production of the grid chambers, there is also the possibility of producing them from plastic and then metallizing the surfaces. In this case, two or more grid chambers can advantageously be combined to form segments whose pitch can be matched to the standardized fluorescent lamps of different lengths.
  • parabolic grid chambers (5 ') it is also very easy to realize different light emission directions on a support plate and with only one light source by means of an oblique cut of the end contour (5'a), based on the respective optical axis.
  • the light cones of the individual louvre chambers of a luminaire grid are thus directed in different directions and can thus be adapted to individual requirements. If a different shape of the holding device between the individual grid chambers is selected instead of a supporting plate, for example a sheet metal frame or lateral guide strips in which the grid chambers are held displaceably, the direction of the light from a lamp can also be changed subsequently.
