  • the invention relates to a luminaire with a luminaire housing for receiving a first optical system, the at least one first lamp for direct and glare-free illumination of the Sehaufgabe, and at least one laterally from the second optical system extending light exit surface.
  • Such a lamp is for example from the German Utility Model DE 299 03 298 of the Applicant known.
  • Luminaire housing is arranged in the middle of the primary optical system, which a grid below a fluorescent lamp for includes direct and glare-free lighting of the visual task. Laterally from the grid are transverse to the longitudinal direction extending, enclosed by two plastic plates hollow Chambers formed, the undersides of the light exit surfaces form.
  • the light exit surface form in the form of a light guide, at the end faces the light generated by the fluorescent lamp is coupled.
  • a disadvantage of the known lights is that the illumination is dependent on the light at the light exit surfaces, what is produced by the first lamp. Sometimes it is too desirable, the light exit surfaces regardless of the to illuminate the first lamp.
  • the invention is therefore based on the object, a Luminaire of the type mentioned in such a way that the Illumination of the light exit surface also independent of the first optical system can be done.
  • This object is achieved in a luminaire of the beginning mentioned type solved in that above the first optical system with the first lamp a second optical System is arranged that at least one second lamp and a light directing system, that of the second lamp emitted light for generating a dynamic light on the Light exit surface directs.
  • the secondary optical system can whose light is separated to illuminate the light exit surface be used by the primary optical system.
  • the primary optical system Compared to the secondary optical system photometrically complete is sealed off, for example, by a corresponding Sheet steel body, the full extent of the primary optical system encloses.
  • the light exit surface is in the preferred embodiment as a plate-shaped light distribution disk for generation a directed and diffuse light scattering formed.
  • a geometric Scattering structure done.
  • the plate-shaped Light emission plate preferably as a one-piece Plastic disc is formed, with a scattering structure, for Example of a groove or prism structure, be provided so that the light can spread diffusely.
  • a scattering structure for Example of a groove or prism structure, be provided so that the light can spread diffusely.
  • it also works as a profile structure with a variety of refractive Surfaces be formed, through which the light also diffused.
  • a particularly homogeneous luminance profile is achieved by a achieved multiple light scattering.
  • the luminaire according to the invention is for this purpose arranged above the light exit plate a lens, so that the light exit lens and the lens between to enclose a hollow chamber.
  • These two in Beam direction superimposed light distribution plates thus form a disk arrangement whose multiple light scattering the light emitted from the second lamp a as homogeneous as possible luminance profile on the lateral Light exit surface generated.
  • the light exit surfaces exist made of light-scattering and translucent, preferably translucent discs or plastic plates.
  • Another light scattering is by using a light-scattering Reflector achievable in the secondary optical system.
  • the light scattering from this reflector and the Diffuser caused light scattering usually causes already such a homogeneous luminance curve that the first light distribution plate, or the visible light exit surface not necessarily light-scattering, but only must be designed to be translucent.
  • the luminaire according to the invention is as flat and elongated extending field lamp formed.
  • at least the first light generating unit comprises a or a plurality of elongated fluorescent lamps; it will to achieve a homogeneous luminance over the entire Length of the light also the second light generating unit one or more elongate fluorescent lamps.
  • the second light generating unit is three over each other arranged fluorescent lamps, preferably vertically to each other with respect to the central axis of the Luminaire are arranged, can be switched on by selective the fluorescent lamps the luminance at the light exit surface be varied.
  • fluorescent lamps with different Use light colors for colored illumination the light exit surface can be switched on by selective the fluorescent lamps the luminance at the light exit surface be varied.
  • the individual fluorescent lamps of the second optical system independently are dimmable from each other;
  • the light steering system of the second optical system is as before mentioned, preferably formed as a light-scattering reflector.
  • This light-diffusing reflector preferably extends from the top of the second light generating unit up to the top of the lens.
  • This light-scattering reflector is preferably designed as a sheet steel body whose free Longitudinal edges are folded over to increase the longitudinal stiffness.
  • the first optical system is completely independent of the second optical system operable, that is without unwanted Stray light entry of one optical system into the other, if the first optical system is completely sealed off in terms of lighting technology is from the second optical system.
  • This can for example, by a grid body, the first completely encloses optical system. In this grid body then the second optical system can be arranged and on the outside attached the light exit lens and the lens become.
  • the first optical system arranged approximately centrally with respect to the lamp housing and the light exit surfaces extend on both sides laterally from the first optical system.
  • the luminaire according to the invention is preferably as recessed luminaire be formed in a suspended ceiling in known Way is used. Alternatively, if sufficient Room heights but also the training as a surface-mounted luminaire possible.
  • a truncated pyramid in cross-section In the middle of the housing 10 is a truncated pyramid in cross-section Reflector 16 attached, extending from the center the upper end of the lamp housing 10 to the upper side a diffusion plate 18 extends. Below the reflector 16 are three vertically aligned to the central axis of the luminaire and stacked fluorescent lamps 20 for generating arranged the dynamic light according to the invention.
  • Raster body 22 is arranged, which consists of a longitudinally extending sheet metal body with folded over on both sides and mutually parallel walls.
  • the first optical system is arranged, which consists of two horizontally in a plane to each other arranged fluorescent lamps 24 and one in the emission direction arranged below grid 26 consists.
  • This grid 26 is constructed in a known manner from two in the longitudinal direction extending and tapering sidebars 28 with corresponding openings for receiving a plurality of transverse webs 30; Furthermore, a well-known in the middle of these transverse webs V-reflector 32 mounted.
  • the grid 26 is via grid locks on the inside of the grid body 22 releasably secured.
  • the side profiles 34 extend convexly from the lower edge of the raster body 22 up to a height to the edge of the lamp housing 10, the approximately at the height of the upper tangent of the fluorescent lamps 24 lies.
  • the side profiles 34 go at its outer edge in one short vertical section 36 and then in a inwardly projecting horizontal section 38 on, in the installed position abuts against the flange of the lamp housing 10.
  • an upward projecting vertical web 40 is integrally formed on the side profile 34. This Vertical web 40 is located on the outside of the inside of the Luminaire housing 10 on and inside is in installation position against this upwardly folded edge of the reflector 16 at.
  • the lens 18 extends from a translucent plastic from the outsides of the grid body 22 to the End of the horizontal section 38 of the side profile 34th Bei der Mounting these lenses 18 in the outside of the Grid body 22 trained grooves 44 used and so far inserted until the oblique outer edge of the lens 18th against the corresponding beveled inner edge of the horizontal section 38 is present. Thus, they close on both sides from the grid body 22 outwardly extending side profiles 34 and the outwardly extending lenses 18 between each one outwardly converging light chamber one.
  • the light emitted by the fluorescent lamps 20 is from the light-diffusing reflector 16 and the lenses 18 and the light scattering side profiles 34 multiply scattered to produce a homogeneous luminance profile on the side profiles 34, which form the light exit surfaces.
  • the fluorescent lamps 20 independently dimmable.
  • the fluorescent lamps 20 are at the front ends in a known manner in versions 46th used on a socket carrier plate 48 in the installed position are vertically locked on top of each other.
  • This socket carrier plate 48 has at its lower end an inwardly bent Horizontal section on top of the screen body 22 is screwed.
  • the luminaire according to the invention are the same or the same effect Parts are provided with the same reference numerals.
  • Figs. 1 and 2 - upper - fluorescent lamps 20 by two laterally radiating LED panel 50 with high luminosity (called power) LED's) replaced.
  • the plate-like, vertically arranged LED Panels 50 sandwich a space therebetween the operating device 52 is arranged for the LED panels 50 is.
  • the operating device for the - lower - fluorescent lamps 24 is the upper side of the lamp housing 10 in the intermediate space between the diffusely scattering reflector 16 and the underside arranged the lamp housing 10.
  • the advantage of LED panels 50 lies in the low height, which is about this can be realized. This height is up to 60 percent low than when using fluorescent lamps.
