Definitions

  • the invention relates to a lighting system, in particular for uniformly illuminating limited work surfaces, consisting of at least one light source and a reflector assigned to it.
  • Known lighting systems usually do not allow individual adaptation of the lighting to the respective workplace, are often critical with regard to the glare required in computer workplaces and generally do not allow the position of the workplaces to be changed without impairing the lighting quality of the workplace concerned.
  • the object of the invention is to provide a lighting system of the type specified in the preamble of claim 1 in such a way that an optimal, glare-free illumination of the respective workplace is achieved without the need for light planning that encompasses the entire entire space and thereby does not impair the usable area of the ar working area must be accepted.
  • the lighting system should also be suitable for individualizing the individual workplace and its effectiveness should not be impaired even if changes have to be made in the respective position of the workplace.
  • the reflector is designed as a large-area reflector that at least partially spans the respective work surface and is held on at least one vertical support, and that at least one light source that radiates against the large-area reflector is held on at least one vertical support in the area between the work surface and the large-area reflector is.
  • the large-area reflector on the vertical support is designed to be adjustable with regard to the distance and / or the inclination to the work surface and, above all, its intrinsic curvature can also be changed is, so that in each case the desired uniformity of the work surface lighting and the desired brightness can be achieved, specifically for the respective workplace and independently of neighboring workplaces.
  • the vertical support advantageously consists of individual sections which can be coupled and mutually fixed, these individual sections comprising support sections and supporting functional sections for light sources and ballasts can be combined as desired.
  • the couplings between the individual sections are designed both as mechanically stable plug-in, latching or screw connections, and are preferably provided with electrical coupling units which inevitably ensure the necessary electrical connections when the mechanical coupling is carried out.
  • the mechanical coupling can take place via conically interlocking elements, the electrical connection parts being arranged concentrically and the positive and non-positive connection between the two mechanical parts to be coupled being achieved via a screw sleeve.
  • the electrical connection elements can be used in pin-sleeve form or in the form of concentric contact elements.
  • a diagonal division can be provided in such a way that a mechanically stable triangular beam that absorbs all mechanical loads is combined with a likewise triangular receiving space for the electrical functional elements.
  • the light source assigned to the large-area reflector is combined at the same time with at least one direct emitter, one direct light source or one light source delivering both direct light and indirect light via the large-area reflector.
  • a separate additional light source which is also preferably held on the vertical support, can be used.
  • the brightness is preferably selected so that direct light and reflected light have the same brightness on the work surface, thus ensuring the typical softness of the indirect light and the required absence of shadows on the entire work surface.
  • Fig. 1 shows an example of a piece of work furniture a desk 1 with a work surface 2, which is illuminated by means of the individually adapted to this work surface 2 lighting system according to the invention in accordance with the respective requirements with indirect and direct light in an optimal way, since there are no disturbing structures and there is no shadow formation.
  • the lighting system comprises a vertical support 3, which can be provided with a stable base, but is preferably coupled directly to the desk 1 via an interface connection unit, as well as a large area reflector 4 and one attached to the vertical support 3 Light source 5, which radiates against the large area reflector 4 at predeterminable angles.
  • ballast 6 is required for the light source 5
  • this ballast 6 is preferably designed as a separate unit, likewise held on the vertical support 3. This has the essential advantage that the ballast is not affected by the heat development of the light source, which is of particular importance for electronic ballasts and increases their long-term functionality.
  • the large-area reflector 4 extends over a substantial part of the width of the working surface 2 and can be designed, for example, in the form of an acute-angled, curved sail, which is realized by means of a tensioning frame 10, which is covered with a suitable reflective material.
  • the large area reflector 4 is preferably attached to the vertical column 3 by means of a lockable swivel or ball joint 7 and can be equipped with a suitable counterweight 8.
  • the lockable joint 7 can be telescopically extendable for the height adjustment of the large-area reflector 4, but it is also possible to adjust the height by inserting an intermediate piece, since the vertical support 3 preferably consists of modular sections to be connected to one another, in particular to be screwed together, both of which only support function possessing individual sections are provided, as well as carrier sections in the form of functional units, such a functional unit comprising, for example, a light source or a ballast.
  • the light source 5 can also be combined with a direct emitter 9, which is also optionally designed to be directional and enables additional small-area irradiation of the work surface with the brightness of the indirect light of corresponding brightness.
  • a direct emitter 9 which is also optionally designed to be directional and enables additional small-area irradiation of the work surface with the brightness of the indirect light of corresponding brightness.
  • Fig. 2 shows in a highly schematic manner a possible embodiment of a connection or interface unit 11, as it can be integrated in the manner of a standard unit in work furniture in the edge or corner area, so that a lighting system according to the invention can then be connected without difficulty and the required stability of the lighting system is ensured by the coupling with the work furniture.
  • the interface unit 11 is shown in FIG. 2 in the left part in a first embodiment provided with a flange 18 and in the right part in a second flange-free embodiment for a pipe coupling.
  • the tubular vertical support 3 is screwed to a coupling sleeve 12, and this coupling sleeve 12 has a conically tapering end which engages in a sleeve 20 which is complementary and is provided with either a flange 18 or an external screw thread and with respect to this sleeve 20 can be fixed by means of a clamping screw member 14.
  • This clamping member 14 engages over an annular shoulder of the coupling sleeve 12 and in this way allows an extremely stable clamping fixation to be achieved by a simple screwing operation.
  • the advantage of this construction is that the outer diameter of all visible cylindrical parts is the same, so that in the assembled state there is a harmonious connection of the respective vertical support 3 to the connection unit 11.
  • the embodiment variant according to FIG. 3 differs from the embodiment according to FIG. 1 essentially in that the large-area reflector 4 is assigned a light source 5 in the form of a tube lamp, which extends over a substantial part of the width of the working surface 2 and possibly downwards can be shielded from the working surface 2 by a preferably adjustable screen.
  • a light source 5 in the form of a tube lamp, which extends over a substantial part of the width of the working surface 2 and possibly downwards can be shielded from the working surface 2 by a preferably adjustable screen.
  • an additional light source 16 for example in the form of a spotlight, can also be attached to the vertical support above the large area reflector 4 in order to obtain a defined room illumination independently of the individual workplace lighting guaranteed by the lighting system according to the invention.
  • FIG. 4 shows a further embodiment of the invention, in which the light source 5 assigned to the large-area reflector 4 is spaced apart from the vertical support 3 and is designed such that a direct light source 17 can be effective approximately in the region of the center of the work surface 2.
  • the direct light source 17 is preferably identical in terms of the light means used to the light source used to generate the indirect light, in which case a transparent area is provided on the work surface side, which is selected so that there is at least essentially on the work surface for the direct and indirect light gives the same brightness.
  • a direct light source 15 which is preferably designed to be horizontal and / or pivotable in a vertical plane, can optionally or alternatively be integrated in the structure of the vertical support 3 consisting of individual sections can be used optionally without affecting the usable work surface 2.
