Definitions

  • the invention relates to an aerodynamic component, a flat floodlight having such an aerodynamic component and an aerodynamic kit comprising a flat flood light and a plurality of such aerodynamic components.
  • Flat floodlights or floodlights are known from the prior art. These are usually used to illuminate an area over a large area. Exemplary applications are generally in (sports) arenas, in a stadium for large-area illumination of a sports field, on an airport for large-area illumination of an airfield, on a bridge or as street lighting.
  • the flat floodlight is mounted here at a certain height, for example, on a mast, so as to illuminate the area over a large area.
  • the floodlit surface is often exposed to wind.
  • the flat flood light also has a large standing in the wind surface or attack surface, the forces acting on the surface flood light force or wind load is relatively large. As a result, the floodlight surface is exposed to high loads.
  • the ability of a floodlight to absorb wind loads can be expressed in terms of the sex value.
  • the sex value of current floodlights is in the range of more than 0.4 m 2 , in particular 0.47 m 2 . Since the flat flood lights are thus exposed to high wind loads, they must - correspondingly costly dimensions and / or be serviced correspondingly often - especially with regard to the safety requirements. This relates in particular to the flat floodlight receiving fastening system.
  • the object of the present invention is to overcome the above-mentioned disadvantages of the prior art.
  • a solution is to be found in order to retrofit existing flat floodlights accordingly, so that the wind loads acting on such a flat floodlight are reduced.
  • the task is to reduce the Scx or C w value of existing floodlights.
  • an aerodynamic component for reducing the flow resistance of a flat flood light has an aerodynamic side and is further adapted to be mounted on the surface flood light, so that when the aerodynamic component is mounted on the surface flood light, the aerodynamic side reduces the flow resistance of the flat flood light.
  • an aerodynamic side is understood to mean a side of the aerodynamic component which faces the flow or via which a flow of the wind, which acts on the flat flood light, sweeps.
  • a flat floodlight can thus be easily retrofitted with the aerodynamic component in order to improve the aerodynamic properties of the flat flood light.
  • the aerodynamic side causes in particular that turbulences that arise when the surface flood light is flowed around by an air flow can be reduced. Consequently, the Scx resp. Cw value of the flood light and thus also the resulting wind load acting on the surface flood light.
  • the sex value can be improved or reduced, in particular to less than 0.35 m 2 .
  • the surface flood light ie in particular its attachment system, dimensioned with less material and thus be made more compact.
  • life of a retrofitted with such an aerodynamic component flat flood light is increased.
  • the flat flood light can thus be made narrow or slim, it also results in an attractive appearance of the flood light despite relatively high wind loads.
  • a thermal optimization of the surface flood light was observed due to the improved air flow.
  • the aerodynamic side is curved / arcuate, convex and / or streamlined. Consequently, the flow resistance of the aerodynamic component and thus also of the flat flood light is further reduced.
  • the aerodynamic side is formed substantially closed.
  • the design of substantially closed is understood to mean that the aerodynamic side is essentially smooth and continuous or without interruptions, ie. H.
  • connection structures such as holes formed. This in turn benefits the flow resistance of the aerodynamic component and thus also the flow resistance of the flat flood light.
  • the aerodynamic component may have a mounting region / mounting section for fastening the aerodynamic component to floodlight-provided regions that preferably correspond to the mounting region.
  • the areas provided at the floodlight can be, for example, the frame and / or frame elements of the flat flood light.
  • the flat floodlight can be easily retrofitted with the aerodynamic component.
  • the mounting area or fastener formed therewith may be designed in such a way that no additional fastening means have to be provided on the floodlight, ie an attachment of the aerodynamic component is possible only with the mounting area of the aerodynamic component or without tools.
  • the aerodynamic component is preferably mounted on the planar floodlight via a longitudinal side, a width side and / or a side (rear side) of the aerodynamic component facing away from the aerodynamic side. If the aerodynamic component is thus mounted on the planar floodlight via one or more of these sides, it can be ensured that corresponding fastening means do not influence the aerodynamics of the aerodynamic side. This in turn benefits the flow resistance of the aerodynamic side and thus the flow resistance of the flat flood light.
  • the longitudinal side, the width side and / or the side facing away from the aerodynamic side (back) of the aerodynamic component on the mounting area are preferably mounted on the planar floodlight via a longitudinal side, a width side and / or a side (rear side) of the aerodynamic component facing away from the aerodynamic side.
  • the aerodynamic component can be designed to be adjustable, in particular pivotable, to the flat floodlight.
  • the aerodynamic component can be easily adapted to the prevailing conditions.
  • the aerodynamic component can thus be mounted on different surface floodlights.
  • the invention relates to a flat floodlight with at least one flat radiating surface as well as an edge region surrounding the planar radiating surface.
  • the planar flood light also has at least one aerodynamic component as described above, preferably a plurality of aerodynamic components as described above, which is mounted in the edge region in such a way that the aerodynamic side reduces the flow resistance of the flat flood light.
  • the flat flood light can also have only a flat radiating surface. If the flat floodlight flows around wind, turbulences which occur in particular in the respective edge region can be easily reduced with the at least one aerodynamic component. Consequently, the flow resistance or the Cw value of the flat flood light is reduced. The resulting on the surface flood light wind power is thus reduced and the surface flood light can be correspondingly better dimensioned, so in particular made more compact. In addition, the flat flood light gets a longer life because of the thus reduced flow resistance.
  • At least one of the at least one aerodynamic component can be mounted in an upper region of the flood light.
  • the upper region of the flood light In the mounted state of the flat flood light in which the flat flood light illuminates, for example, a large radiating surface, the upper region of the flood light generally corresponds to the highest region of the flat flood light. Since the wind currents and thus in particular the turbulences occurring are particularly strong at this area, a reduction of the flow resistance at this area brings about a particularly advantageous reduction of the flow resistance of the flat flood light. Thus, in particular, the torque acting on the floodlight and the floodlight mounting system is reduced. It has been found in particular that the Cw value can be improved, in particular by up to 10% or even more can be reduced.
  • At least one of the at least one aerodynamic component can be mounted in a lateral region of the flood light.
  • a lateral area is usually exposed to a wind flow head-on. If the flat flood light is thus additionally or only exposed to a wind flow parallel to the areal radiating surface, the flow resistance of the flat flood light can also be reduced with respect to this direction. This, in turn, benefits in particular the service life and the more efficient dimensioning of the surface flood light.
  • At least one of the at least one aerodynamic component can be mounted in a lower region of flood light.
  • the lower region corresponds in particular to a region or edge region of the flood light which is closest to the ground.
  • turbulences are reduced at a lower portion of the surface flood light, so that the flow resistance of the flat flood light can be further reduced. It has been found in particular that the Cw value can thus be improved, in particular by up to 20% or even more reduced.
  • the aerodynamic component may be spaced from and preferably mounted to the edge region. As a result, in particular, the aerodynamic component reduces the flow resistance of the flat flood light without influencing the light emission of the flat flood light.
  • the flat flood light may have at least two, preferably three or more flat radiating surfaces.
  • Such a flat flood light - for example, also provided via a single radiating surface and / or a single flood light module - thus has a particularly large standing in the wind surface.
  • the aerodynamic component can reduce the resulting resulting wind load by reducing the aerodynamic component or the Cw value of the surface flood light.
  • At least one of the at least one aerodynamic component may be mounted between adjacent radiating surfaces or in the gap between adjacent radiating surfaces.
  • the at least two flat radiating surfaces are pivotable, in particular provided pivotably in the same direction.
  • the axes of rotation of the at least two flat radiating surfaces can point in the same direction.
  • the planar floodlight can furthermore have a bearing area that preferably accommodates the at least one emitting surface in a pivotable manner. At least one of the at least one aerodynamic component can then be mounted in or on the storage area.
  • the flow resistance, in particular of the storage area can be reduced since, in particular, turbulences in the area of the storage area are reduced because of the aerodynamic component.
  • the storage area can also be provided for mounting the floodlight, for example on a mast or on a roof.
  • Corresponding fastening means for mounting the floodlight usually cause turbulence, which, however, can be reduced by mounting the aerodynamic component to the flat floodlight or to the storage area.
  • the invention relates to an aerodynamic kit for reducing the flow resistance of a flat flood light.
  • the kit features a floodlit surface and aerodynamic components as described above.
  • the aerodynamic components can be mounted in the edge region of the areal radiating surface of the flat flood light in order to reduce the flow resistance of the flat flood light.
  • a kit is provided which can adapt the flat flood light to the prevailing flow conditions simply by means of the aerodynamic components.
  • the flat floodlight or its fastening system therefore does not have to be correspondingly dimensioned in order to be adapted to the respectively prevailing flow conditions. Rather, it is sufficient to mount several (different) aerodynamic components of the aerodynamic components to the surface flood light, for example, as described above, so that the surface flood light stands steadily in the prevailing flow.
  • FIG. 1 shows, by way of example, a planar floodlight 1, for example in the form of an LED radiator, with at least one flat radiating surface 2.
  • the planar floodlight 1 has three flat radiating surfaces 2.
  • the flat floodlight 1 is not limited to a specific number of flat radiating surfaces 2.

  • the flat radiating surface 2 and the surrounding edge region are not limited to a specific shape.
  • FIG. 1 illustrated flat flood light 1 takes example, the flat radiating surface 2 pivotally. That is, the area radiating surface 2 can be pivoted about an axis of rotation, so as to adjust the light emission accordingly.
  • this axis of rotation runs in the longitudinal direction of the radiating surface 2.
  • the axis of rotation is preferably such that the axis of rotation is at least partially hidden from view of the flat radiating surface 2 thereof.
  • the area radiating surfaces 2 are each provided pivotably, in such a way that they are provided pivotably in the same direction. That is, the axes of rotation of the plane Radiating surfaces 2 point in the same direction.
  • the flat radiating surfaces 2 can be pivoted depending on or independently of each other. In the example shown here, the flat radiating surfaces 2 are provided independently pivotable. The flat radiating surfaces 2 can thus be pivoted separately from each other, thus causing a desired radiation of the flat flood light 1.
  • FIG. 1 further shows a storage area 3, which receives the at least one area radiating surface 2, that in the present case, the three flat radiating surfaces 2, pivotally.
  • a storage area 3 which receives the at least one area radiating surface 2, that in the present case, the three flat radiating surfaces 2, pivotally.
  • two storage areas 3 are provided, so that the at least one area radiating surface 2 between these storage areas 3 is pivotally received by the storage areas 3.
  • the at least one flat radiating surface 2 and the bearing region 3 can each have mutually corresponding bearing areas, so that the at least one radiating surface 2 is accommodated in a correspondingly pivotable manner by the bearing area 3.
  • the storage area 3 can also be designed to mount the flat floodlight 1 on a mast or on a roof.
  • the storage area 3 can have a flange area which can provide the planar floodlight 1 pivotably and / or non-pivotably on a mast or on a roof.
  • FIG. 1 indicates that a floodlight module 4, for example in the form of an LED floodlight module, can have the areal radiating surface 2.
  • the flat radiating surface 2 can be provided by the floodlight module 4.
  • several, ie preferably three, floodlight modules 4 are accordingly provided, each of which has one of the two-dimensional radiating surfaces 2.
  • the respective floodlight module 4 can thus have the areal radiating surface 2 on the front side.
  • the floodlight module 4 can have a heat sink, in particular cooling fins, in order to cool the components necessary for the operation of the luminaire.
  • the floodlight module 4 has light-emitting means, in particular LEDs, in order to effect radiation via the flat radiating surface 4.
  • the floodlight module 4 can also have a housing, which in particular accommodates the lighting means and / or has the cooling ribs on the rear side.
  • FIG. 2 shows by way of example a first embodiment of an aerodynamic component 100.
  • the aerodynamic component 100 has an aerodynamic side 101.
  • the aerodynamic side 101 may be bent and / or convex be educated.
  • the aerodynamic side 101 as shown, may be substantially curved in cross-section and / or convex, for example in the form of a partial or quadrant circle. It can be seen that the aerodynamic side 101 extends from the front side of the flat floodlight 1 to its rear side or further.
  • the aerodynamic component 100 is further designed to be mounted on the flat floodlight 1. As in FIG. 2 illustrated, the aerodynamic component 100 can be mounted in particular on a longitudinal side of the aerodynamic component 100 to the flat flood light 1. Alternatively or additionally, it may also be provided that the aerodynamic component 100 is mounted on the planar floodlight 1 via a width side and / or a side facing away from the aerodynamic side or the rear side of the aerodynamic component. In particular, the aerodynamic component 100 can also be adjustably mounted on the flat flood light 1, in particular such that it can be pivoted on it, so as to adjust the aerodynamic component 100 in accordance with the respective prevailing conditions.
  • the aerodynamic component 100 may have a mounting region 102 or fasteners that are not illustrated in greater detail with this mounting region 102.

  • the aerodynamic component 100 is mounted in a longitudinal side of the edge region by way of example.
  • the edge region of the areal radiating surface 2 is usually in direct contact with an air flow or wind acting on the flat flood light 1.

  • This state of the flat flood light 1 without the aerodynamic component 100 mounted on the flat flood light 1 is shown by way of example in FIG FIG. 1 shown.
  • the aerodynamic component 100 By attaching the aerodynamic component 100 in this edge region, such as in FIG. 2 shown, these turbulences are now reduced, so that the aerodynamic component 100, in particular its aerodynamic side 101, reduces the flow resistance of the flat flood light 1.
  • the aerodynamic component 100 may extend in particular over the entire length of the flat radiating surface 2 and the respective longitudinal edge region, so that along this entire length of the flow resistance or in particular turbulence can be reduced.
  • the aerodynamic component 100 is mounted in a lower region of the flat flood light 1 by way of example. Since that in FIG. 2 shown flat flood light 1 has several, in particular three flat radiating surfaces 2, the aerodynamic component 100 is therefore mounted in the lower edge region of the lowermost radiating surface 2. On the flat flood light 1 acting wind is deflected, inter alia, to this lower edge area. The attachment of the aerodynamic component 100 can thus at this lower edge region, which is usually an edge region of the radiating surfaces 2, which is closest to the ground, swirls and thus reduce the Cw value of the flood light 1.
