Definitions

  • Embodiments of the present invention relate to a lighting device and a system comprising two lighting devices.
  • Head moving systems typically include a base or fixed unit and a base unit pivotable lighting unit.
  • the lighting unit typically comprises one or more lighting elements, such as e.g. Light bulbs, LEDs or other bulbs, by means of which a light cone can be generated with a predetermined by the housing or the housing opening orientation.
  • the entire lighting unit is typically pivotally arranged relative to the base by means of one or more joints, wherein the pivoting process can be carried out either manually or remotely controlled.
  • Both the fixed and the moving head systems differentiate between single spots and arrays.
  • arrays By means of arrays it is possible to achieve a uniform illumination over at least a flat area.
  • the flexibility of such arrays is severely limited, which is why in many areas of use the spots are again resorted to, which are then individually positioned next to one another in a complex manner, so that a uniform illumination can take place. Therefore, there is a need for an improved approach.
  • the object of the present invention is to provide a device or a system which can be used flexibly and at the same time enables a good areal illumination.
  • Embodiments of the present invention provide a lighting device with an elongate pedestal and a pivotable elongated lighting unit.
  • This pivotable, elongated illumination unit is pivotably mounted about a longitudinal axis by means of at least one joint. Parallel to this longitudinal axis extends both the elongated base and the pivotable, elongated lighting unit. In particular, the elongate extent of the pivotable, elongated lighting unit is limited by two opposite side surfaces.
  • the illumination unit comprises at least two illumination elements which are arranged along the pivotable axis, so that a distance between two adjacent illumination elements corresponds to a 1.5 to 2.5 times the distance between a luminous element positioned adjacent to a side surface and the corresponding side surface.
  • a system is provided with at least two lighting devices.
  • a distance between two luminous elements positioned adjacent to the adjacent side surfaces of the two illuminating devices is 0.5 to 1.5 times the distance between two adjacent luminous elements of one of the two illuminating devices.
  • embodiments of the present invention are based on the recognition that uniform illumination can be achieved by means of a system comprising a plurality of elongate illumination devices each having a plurality of luminous elements arranged along the longitudinal axis when the individual elongated illumination devices are so configured, that even when juxtaposing a plurality of elongated lighting devices, a distance between the individual lighting elements remains substantially constant.
  • the distance between a luminous element, which is arranged at the edge, ie adjacent to the next lighting device, and the respective outer side of the lighting device is selected in dependence on a distance between two adjacent lighting elements in the lighting device itself.

  • the elongate base preferably has a smaller or maximally equal elongated extent than a region of the pivotable, elongated illumination unit.
  • This geometric arrangement has been found to be advantageous in terms of the desired juxtaposition of multiple lighting devices.
  • the above-mentioned recesses also offer the advantage that lighting-relevant elements, such as e.g. the optics can be arranged in a protruding region, that is to say overlapping the recess and the leg arranged in the recess.
  • the lighting device is preferably pivotable by at least 180 ° or more. This can be realized, for example, that the above-mentioned legs or generally the base is made waisted.
  • the pivoting can also be done remotely via a control panel or generally remotely controlled via a corresponding interface.
  • the lighting device then comprises means for the motorized pivoting of the pivotable, elongated lighting unit. These may for example comprise a motor arranged in the elongated base, a pinion fixedly connected to the pivotable, elongate lighting unit and / or a drive belt.
  • each elongate illumination unit comprises a plurality of illumination elements arranged along the elongate extent of the pivotable, elongate illumination unit or, in particular, regularly arranged illumination elements, such as, for example. LEDs.
  • the individual lighting elements may be coupled with lenses that allow a focused radiation in the form of a lighting cone.
  • the lenses can according to further embodiments additionally be designed to focus the illumination cone. In this case, a distance between the illumination element and the respective lens is then varied. The adjustment of the distance can be motorized or even by hand erfoigen.
  • the plurality of lenses for the plurality of illumination elements may also be designed as a lens arrangement, thus in one unit.
  • a distance between two adjacent lenses is then selected so that it corresponds to 1.5 times to 2.5 times the distance between a lens positioned adjacent to the side surface and the corresponding side surface.
  • the lens arranged on the edge may be arranged overlapping this recess and thus overlapping to the leg or the bearing block.

  • the longitudinal extent, in particular of the pivotable, elongate illumination unit 14 is limited by two opposite side surfaces 14a and 14b.
  • the elongate illumination unit 14 has a rectangular base body whose side walls are just the side surfaces 14a and 14b, while so-called longitudinal surfaces are arranged between these surfaces 14a and 14b.
  • the at least two lighting elements 20a and 20b are arranged.
  • the arrangement of the lighting elements 20a and 20b takes place taking into account certain distance specifications.

  • the distance x 20ab is even only 1.9 times to 2.1 times the distance a 14a and a 14b, respectively.
  • the distance x 20ab is as exactly as twice as large as the distance a 14a or a 14b . Namely, all of these distance conditions result in that, when the lighting device 10 is used in combination with another lighting device 10 '(dashed line in FIG The distance x 20ab of adjacently arranged luminous elements of the two illuminating devices 10 and 10 ', in this case, for example, 20b' and 20a is approximately the same as the distance a 20ab . This results in a regular arrangement or distribution of the lighting elements 20a, 20b, 20a ', 20b'.
  • each of the lighting device or, more precisely, each elongated lighting unit has a plurality of lighting elements. These can all be arranged along the longitudinal extent. As already indicated above, the regular arrangement with regard to the light distribution is preferred. Thus, within a lighting unit 14, an approximately constant distance a 20ab is desired. Here, 0.75 times to 1.25 times, or even 0.9 times to 1.1 times, one distance in relation to the other distance is considered substantially constant.
  • the engagement between the pivotable, elongated illumination unit 14 and the base 12 can be designed differently.
  • the intervention takes place by a hinge, which is arranged between a leg 12a of the base 12 and a portion 14t of the illumination unit 14.
  • the lighting unit 14 is provided in the region 14t with a recess 14g, so that legs 12a and 14t, through which the pivot axis 16 passes, may be arranged side by side, without negatively affecting the overall dimensions of the lighting device 10.
  • the recess 14g is deeper in the longitudinal direction than the leg 12a is wide, so that the leg 12a and the side surface 14a are flush or the surface of the leg 12a is recessed with respect to the side surface 14a.
  • a flush closure is understood to mean a closure in which the surfaces (14a and surface of the leg 12a) are arranged with a maximum offset of 1 mm or 5 mm.
  • Each lighting device preferably, but not necessarily, comprises two side parts or laterally arranged legs 12a, between which the area 14t of the lighting unit 14 is arranged.
  • Fig. 2a-2c show side views of the lighting device 10 with base 12 and pivotable, elongated lighting unit 14.
  • the base 12 here again includes the laterally disposed leg 12a, which can also be referred to as a bearing block.
  • the lighting device is pivoted in a different direction, so that the light cone 22 either to the left ( Fig. 2a ), up ( Fig. 2b ) or to the right ( Fig. 2c ) is aligned.
  • the light cone 22 or its direction is through the opening 14 o (see also Fig. 1 ).
  • Fig. 1 it can also be seen that all lighting elements 20a and 20b face towards this opening 14o.
  • a kind of projection 14s of the illumination unit 14 is formed in the region of the opening 14o (cf. Fig. 1 ).
  • the mobility or pivoting of the lighting unit 14 may be limited.
  • the leg 12a is shaped accordingly.
  • this has a round shape, which curves around the longitudinal axis 16, so that the pivoting of the illumination unit 14 is made possible.

  • the angular range may preferably include at least 180 °, if not more, such as 210 °.
  • Fig. 3a shows the lighting device 10 from Fig. 2 , wherein the base 12 and in particular of the legs 12a is shown cut.

  • the illumination unit 14 therefore has engaging portions 36, eg a pulley, which is fixedly coupled to the illumination unit 14.
  • the motor 34 may be implemented, for example, as a stepping motor or high-resolution stepping motor.

Fig. 1 ).
  • the light-emitting elements can also be arranged in a region 14t of the illumination unit which is arranged between the legs, ie not in the widened, protruding head part, since the light rays of the last LED in the series only spread to the full width of the zoom lens when it was in the spot position.
