VERSATILE ADJUSTABLE MAST OUTDOOR LIGHT

Description

[0001] The invention generally relates to a set for realizing an outdoor light designed as a mast light, often also referred to as a mast-mounted or mast-topped light, depending on whether it is attached to a connecting piece at the upper end of a preferably tubular mast with a lower end fixed in the ground or is attached to a connecting piece preferably projecting laterally from the mast, as well as an outdoor light produced by means of the set.

[0002] In particular, the invention relates to a mast light with a luminaire housing comprising an interior of the housing designed to accommodate a light source, further luminaire components, a preferably front-facing light emission opening for the emission of a luminous flux generated by the light source, and a connection piece formed on an outside of the luminaire housing for connecting the luminaire housing to a mast that sits on a ground or other fastening elements. State of the art

[0003] Such pole-mounted lights are typically made of metallic materials or at least fiberglass-reinforced plastics. Due to globally changing weather patterns, these pole-mounted lights are increasingly exposed to stronger wind loads, particularly because of the large leverage at the top of poles. An outdoor light is inherently exposed to the prevailing wind speed in its region, necessitating the development of housings of varying strengths for different regions. This increases storage and, consequently, logistics costs for maintaining a diverse inventory. Changing weather conditions are leading to a greater need for outdoor lights in areas that were previously unaffected, lights that can withstand these altered weather conditions.Prior art is disclosed, for example, in EP 2 886 933 A1 and CN 102 818 173 B, each disclosing a luminaire with a housing that is attached to a pole by connecting the pole to a connector, the connector being screwed to the housing by means of a counter plate. Furthermore, JP H03 216907 A discloses a luminaire in which the pole is screwed to the luminaire's connector by means of a counter plate. WO 2008 / 150254 A1 and US 2008 / 273335 A1 also disclose luminaires that, in addition to a housing, have a separate optical element attachable to the housing, which serves to influence the light emitted by the luminaire. From US 3 218 446 A a set for realizing a luminaire is also known, wherein the set comprises several luminaire modules which can be attached in a selectable number to a central luminaire mast module. Technical problem / task

[0004] Based on this state of the art, the invention aims to at least partially avoid these disadvantages and thus provide a set for the realization of a mast-mounted outdoor light which allows for adaptation to changing weather conditions using simple means. invention

[0005] According to the invention, this is already solved in a mast-mounted outdoor light of the type mentioned at the outset by the features of independent claim 1, with advantageous but not essential further developments being set out in the dependent claims.

[0006] According to the invention, the set comprises at least one stiffening element that can be subsequently connected to the housing as required.

[0007] According to the invention, a "stiffening element" is understood to be a spatial stiffening structure designed to stiffen the luminaire housing. Such a stiffening element can optionally be combined with a luminaire, particularly if the operating conditions of the luminaire entail higher external loads and thus stiffening the original luminaire housing appears advantageous.

[0008] To stiffen the luminaire housing, the stiffening element can in particular have a plurality of non-adjacent contact points with the luminaire housing, wherein a first contact point is designed and provided to transmit a force from the stiffening element to the luminaire housing and / or the connector and / or the mast, and wherein a second contact point is designed and provided to transmit a force from the luminaire housing to the stiffening element, wherein a first contact point is arranged closer to the mast and / or the connector than a second contact point when viewed radially from the mast and / or the center of gravity of the connector.

[0009] In particular, a first contact point is arranged at a distance of 0 to 0.2 of the maximum radial extent of the luminaire housing emanating from the mast and / or the center of gravity of the connecting piece, preferably at 0 to 0.15 and especially preferably at 0 to 0.1 of the maximum radial extent, and a second contact point is arranged at a distance of 0.15 to 1 of the maximum radial extent, preferably at 0.2 to 1 and especially preferably at 0.4 to 1 of the maximum radial extent.

[0010] Alternatively, a first contact point and a second contact point can also be positively connected to each other via the luminaire housing, while maintaining the characterization of the contact points with regard to their radial extent. It should be expressly noted that the values ​​for the distance of the contact points from the mast and / or the connector should not be understood as strict limits, but rather can be exceeded or fallen short of within engineering parameters without deviating from the described aspect. In simple terms, the values ​​are intended to provide a guideline for the size of the distance of the contact points from the mast and / or the connector proposed here.

[0011] The term "can be arranged retroactively as required" means that the stiffening element can optionally be combined with the luminaire, although it is not required for the safe operation of the luminaire in an environment protected from environmental influences.

[0012] This stiffening element is designed as a stiffening element or additional element that can be inserted into the luminaire housing. The stiffening element thus represents a modular retrofit element that can be subsequently connected to the luminaire housing or inserted into the basic form of the luminaire housing. It preferably comprises or consists entirely of metal, particularly steel, or reinforced plastic and is designed to locally reduce component stresses in the luminaire housing, especially in outdoor luminaires, and possibly also in industrial luminaires. In this respect, the stiffening element can also be described, in short, as a "stiffening insert" adapted to the luminaire housing. The stiffening element according to the invention thus provides a cost-effective reinforcement system that reduces the forces caused by horizontal and / or vertical wind loads, as well as additional loads, e.g., from snow or ice.The stiffening element is designed to reinforce the luminaire housing and redirects the stress flow, thereby reducing stress peaks within the housing and preventing the stress from acting locally at a single point. It has been shown that the stiffening element can reduce stresses within the luminaire housing caused by external forces by at least 25 percent, and in special cases even by up to 54 percent, compared to an unreinforced housing. This is preferably achieved by using a stiffening element material with a higher modulus of elasticity than the luminaire housing material. Particularly advantageous results were obtained when the stiffening element had a modulus of elasticity three times greater than that of the luminaire housing material.

[0013] The retrofittable stiffening element not only absorbs wind loads in all possible wind categories or allows the mast-mounted light to be easily adapted to these, but also compensates for other loads on the light housing, e.g. from snow, ice or dynamic loads from vibrations.

[0014] The stiffening element is preferably designed to connect the rigid connecting piece or the mast connection to the luminaire housing. This reduces deformations and strains at the less rigid points in the luminaire housing and lowers stress peaks in the luminaire housing.

[0015] It is particularly advantageous if the stiffening element is arranged in the area of ​​maximum principal stress within the housing, i.e., at the location where the maximum stress occurs in the luminaire housing under wind or weight load. During the development of the invention, it was found that this location of maximum principal stress is, in most cases, situated in the area of ​​the transition from the connector to the luminaire housing. Particularly in the case of luminaire housings that are asymmetrically designed relative to the connector, i.e., which extend further from the connector on one side than on the other, this maximum principal stress occurs in the area between the connector and the longer side of the luminaire housing.

[0016] The stiffening element preferably reflects at least partially or preferably completely the internal geometry of the luminaire housing and thus rests against it at least partially on the inside, in particular on the inner edges of the luminaire housing.

[0017] In a preferred embodiment, the luminaire housing consists essentially of aluminium or aluminium die-casting, and the stiffening element consists essentially of steel or structural steel.

[0018] The luminaire housing, in its basic version without a stiffening element, is therefore suitable for use in all areas. Additionally, the retrofittable stiffening element can be used as an add-on or supplementary product without affecting the favorable entry-level price of the pole-mounted or outdoor luminaire as a basic model. The design according to the invention thus allows, in particular, the needs-based and, especially, subsequent adaptation of a standard luminaire with a conventional housing, e.g., made of die-cast aluminum, to different wind regions without having to maintain different model variants. According to the invention, only the stiffening element required for the respective wind region needs to be inserted into the housing.

[0019] In one embodiment, the stiffening element is designed, for example, as a substantially planar or plate-shaped stiffening plate, which can be inserted into the luminaire housing, particularly in the connection area between the connector and the luminaire housing, because the maximum main voltage regularly occurs in the luminaire housing at this location, i.e., at the point where the maximum voltage peaks usually occur during operation.

[0020] The stiffening element or stiffening plate can be designed to enclose an opening within the mast mounting or the connecting piece. This stiffening plate, disregarding its material thickness, is essentially a two-dimensional element that does not necessarily have to extend in a single plane, but can also be geometrically adapted to the luminaire housing, e.g., it can be curved.

[0021] The minimum material thickness of the stiffening element or plate is preferably greater than or equal to that of the component or luminaire housing to be reinforced.

[0022] However, particularly stable designs also provide that the material thickness of the stiffening element can be at least in sections 2 or 3 times greater than the material thickness of the lamp housing.

[0023] According to the invention, the connection area is in particular reinforced by the arrangement of the stiffening element in this region, and it has proven advantageous to design the stiffening element in such a way that it also reinforces an area of ​​25 percent to 35 percent around the connection area.

[0024] This stiffening plate may be angled for further stabilization or may have additional stiffening ribs or the like.

[0025] Another particularly easy-to-retrofit design provides for the stiffening element to be formed as a stiffening structure in the form of a bracket or frame that is at least partially, and preferably fully, closed, and which may have two freely opposing arms at the connection end for fastening to the connecting piece, or which may also be designed as a fully closed, polygonal, e.g., square frame.

[0026] This frame can be designed to extend essentially within or along the light emission opening of the luminaire housing when installed. By providing supports between the frame and other areas of the stiffening element, i.e., by designing the truss structure of the stiffening element, loads, such as vertical movements, can be absorbed as required.

[0027] According to the invention, the stiffening element is designed as a space-shaped stiffening structure, which thus defines at least in sections a three-dimensional structure that encloses a stiffening space preferably enclosed at the edge or perimeter by this stiffening structure.

[0028] Preferably, the stiffening element or stiffening structure is designed as a frame-like closed structure with a connection end for fastening to the connector and a support end opposite the connection end designed to rest against the inside of the luminaire housing in the installed position.

[0029] Particularly advantageous is the stiffening structure, at least in sections, designed as a frame- or truss-like structure with rod-shaped struts or supports, which thus define or enclose a stiffening space preferably completely enclosed by the stiffening structure.

[0030] The stiffening structure can include a stiffening plate in addition to the rod-shaped struts, preferably at the connection area, i.e. in the area between the connector and the luminaire housing, where the maximum stress in the housing usually occurs.

[0031] Preferred embodiments of the stiffening structure include the edges and corners or struts and / or plates of the stiffening structure extending along the edges or corners of the luminaire housing in the installed position, thus supporting exactly the corners and edges of the housing on the inside in the installed position and preferably also supporting the other areas with stress peaks in the luminaire housing.

[0032] According to the invention, the stiffening structure is preferably designed to at least partially represent the interior of the luminaire housing, and is thus adapted to the luminaire housing in such a way that it rests against the inside of the luminaire housing in the installed position and thereby supports and reinforces in particular the locations with strong stress peaks in the luminaire housing and / or the edges or corners of the luminaire housing.

[0033] This stiffening structure can also include several plates or stiffening plates that enclose the stiffening space or are assembled into a space-shaped structure, e.g. in the form of a box adapted for insertion into the luminaire housing, which can therefore be inserted into the luminaire housing and can also accommodate the light sources and other electrical components of the mast outdoor luminaire completely or partially.

[0034] A particularly preferred embodiment provides for the stiffening structure to be designed as a stiffening frame with a strut or rod structure, similar to a truss, but which in any case defines a stiffening frame completely enclosed by the struts at their edges or sides, and which preferably does not include any cross braces between individual intersection points of the edge-side struts. Thus, this stiffening structure or stiffening frame impedes the installation and maintenance of the connection technology as little as possible.

[0035] This stiffening frame is particularly stable if it is designed as a closed frame structure, at least along the edges, e.g., if the frame replicates the edges of a cube or rectangle that is adapted for use in the light housing.

[0036] Preferably, these struts of the stiffening structure or stiffening frame are designed such that, in the installed position, they extend along the inner edges or corners of the luminaire housing, thus supporting precisely the inner edges or corners of the housing from the inside. Preferably, additional struts are provided to support other areas of maximum stress peaks or the main stress within the housing.

[0037] The struts are preferably designed such that they include longitudinal brackets which at least partially abut opposite sides of the housing and are preferably spaced apart from each other by at least one connecting crossbar.

[0038] This stiffening plate can have stiffening struts, particularly at the corners, to form the stiffening frame, which then extend along the inside of the housing, thus supporting the housing on the inside and connecting the stiffening space formed by the stiffening struts to the mast or connecting piece, preferably enclosing it.

[0039] In a preferred embodiment, the stiffening plate is curved to adapt to the geometry of the connection area and may have additional stiffening ribs.

[0040] The stiffening element or structure can be connected either only to the luminaire housing or alternatively or additionally to the connector. It is also possible to attach it directly to the top of the mast, either additionally or independently, for example, if a connector is not to be used.

[0041] The luminaire housing and mast connection element are preferably designed in two parts, but can also be designed in one piece if required.

[0042] The stiffening element can be connected to the luminaire housing by insertion, by clamping the joining partners against each other in the installed position, or by welding or bolting. In any case, providing a tight, play-free connection between the joining partners in the installed position is advisable, preferably with an interference fit. In particular, when bolting, the threaded portion and the head bearing surface should be pressed firmly against the joining partners. No contact should be established between the bolt shank and a through hole or blind hole, as the preload can be selected so that the surfaces to be clamped cannot be displaced relative to each other by the load.

[0043] Embodiments include reinforcements on the luminaire housing, at least at the connection point and / or the contact points with the stiffening element. This also includes material reinforcements in the luminaire housing, either at specific points or in sections at the bearing or connection points. For example, housing sections may be thickened, or supports, struts, ribs, or the like may be provided on the housing, particularly on the inside, and especially molded in one piece.

[0044] By providing reinforcements, the stresses on the luminaire housing are significantly reduced, because at least one reinforcement stiffens the luminaire housing and thus prevents the deformations and therefore the strains at critical points from becoming too great.

[0045] Therefore, reinforcing the luminaire housing is advisable, especially in the connection area, but also additionally or solely at contact points of the stiffening element.

[0046] To ensure a particularly stable and durable screw connection, screw bosses (molded receptacles for threads) for receiving the screws at the connection points between the stiffening element and the luminaire housing have proven particularly advantageous, and these are preferably integrated into the luminaire housing. This allows for easy fastening and also achieves a very homogeneous distribution of stresses within the luminaire housing, while simultaneously providing stiffening.

[0047] Embodiments include stiffening elements comprising at least two stiffening struts or brackets connected to the connector and / or the luminaire housing. These stiffening elements preferably rest against the inner surfaces of the luminaire housing in a fork-like manner, with a widening gap between them, and are separated from each other by a transverse web at their ends. Preferably, the stiffening structure is designed to sit in the corners and edges of the luminaire housing when installed, thus achieving particularly high stability of the housing.

[0048] Even better stabilization of the overall system, including the luminaire housing, stiffening element and, if applicable, the mast, can be achieved by including clamping devices that act between the stiffening element and the luminaire housing in the installed position, e.g., by tightening connecting screws or clamping brackets.

[0049] Preferred embodiments provide for material reinforcement on the stiffening element in the form of ribs, flanges, or edges. The stiffening element can either have the same material thickness as the luminaire housing, or a thinner or thicker material thickness.

[0050] In some embodiments, the stiffening element comprises a clamp that can be connected to the mast and, via a further connecting element, to the stiffening elements inside the luminaire housing in the installed position. Preferably, this clamp is designed as a mast clamp that encircles the mast in a ring-like or circular shape in the installed position and is preferably located directly below the luminaire housing around the connection piece.

[0051] Further stability can be increased if the clamp can be connected to the housing via a retaining tab that surrounds the light housing on the outside in the installed position.

[0052] Preferably, the stiffening element or structure is designed such that, in its installed position, it does not impede the installation and maintenance of the luminaire components, such as the light source, other luminaire components like a control gear, light management systems, terminal blocks, possibly surge protection, and additional electrotechnical components. This is preferably achieved by the stiffening structure having spaced-apart stiffening struts to span the virtual stiffening space.

[0053] Preferably, this stiffening element is designed such that the stiffening struts extend along the edges or corners of the luminaire housing in the installed position, or bear against them on the inside. This allows the luminaire components to be inserted and replaced within this stiffening space between the struts.

[0054] Preferred embodiments provide that the material of the stiffening element has a significantly higher modulus of elasticity than the material of the luminaire housing, particularly preferably approximately two to three times higher. For a housing made of die-cast aluminum (modulus of elasticity: 70 GPa (kN / mm²)), the use of a stiffening element made of structural steel (modulus of elasticity: 210 GPa) has proven particularly advantageous. This also allows for space optimization, as the material thickness of the stiffening element can be less than that of the luminaire housing.

[0055] The arrangement and / or design of the stiffening element is particularly advantageous at points of particularly high loads or stresses within the luminaire housing, for example, at or around the connection area (the connection between the connector and the housing). This can be achieved, for example, by incorporating a stiffening plate in the connection area, possibly with additional stiffening ribs.

[0056] It has proven advantageous that the fastening interfaces and / or areas of high stress are partially replaceable (e.g., replacing aluminum die-casting with stainless steel / steel investment casting).

[0057] In some embodiments, the connector and the luminaire housing are adjustable relative to each other. Preferably, locking ribs or detent projections are provided between the joining partners, interlocking in a form-fitting manner when installed. These ribs or projections, when installed, are in contact with each other and allow the luminaire housing to be adjusted relative to the normally stationary connector by loosening screws or other fasteners. The stiffening element is preferably designed to also be adjustable, for example, by forming elongated holes in the fittings.

[0058] The stiffening element can either be inserted into the luminaire housing or, preferably, additionally connected to the inside of the luminaire housing, or is designed for this purpose. Preferred connecting means include clips or snap-fit ​​connections for particularly easy and quick one-handed installation. Screw connections are also possible, allowing for a particularly stable and rigid fastening. Preferably, the stiffening element, or the elements forming the stiffening element (i.e., the plates or walls in the longitudinal direction), is at least once folded, preferably multiple times folded, to achieve higher or improved bending stiffness.

[0059] The invention relates, separately from the outdoor light itself, to a retrofit kit or a stiffening element designed for external connection or insertion into a pole-mounted outdoor light or into the housing of such a light. The stiffening element, or the stiffening structure formed from several stiffening elements, e.g., a stiffening housing, is therefore slightly smaller than the light housing that receives it in its installed position. The light housing encloses and receives the stiffening element externally in its installed position, preferably such that the stiffening element, when installed, rests against the edges and / or corners of the light housing to achieve maximum stiffening. Surprisingly, this design of the retrofittable stiffening element allows the load-bearing capacity of pole-mounted outdoor lights to be increased depending on the design and geometric configuration of the stiffening element.The stiffening structure can be increased by 25-100 percent with only a slight increase in weight.

[0060] The stiffening element should be positioned in the most stressed areas of the luminaire housing to prevent deformation caused by wind, snow, or ice. This is achieved primarily by designing the stiffening element to provide rigidity in the bending direction, meaning it is itself very stiff, which is mainly accomplished by manufacturing the stiffening element from steel.

[0061] By using the stiffening element, especially designed as a stiffening structure, a stress reduction of over 50 percent in the luminaire housing was achieved in a practical application, for example in a mast outdoor light.

[0062] According to the invention, a luminaire housing that withstands the loads in wind zone 2 is provided with reinforcing elements to enable it to withstand higher loads. The majority of outdoor luminaires are installed in zones with low wind loads. Only a small number are used in regions with high wind speeds, but these must be designed to withstand these loads. To avoid having to produce a new casting tool for this small number of luminaires or to provide all housings with a thicker wall thickness, a reinforcing element that can also be retrofitted is proposed for use in high-load zones. This allows a thin-walled luminaire housing to be manufactured cost-effectively in large quantities and, if necessary, subsequently fitted with a reinforcing element that enables the luminaire housing to withstand high loads even in wind zones 3 (wind speed 27.5 m / s) to 4 (wind speed 30.0 m / s) and possibly even higher.reliably protects the housing from excessive stress caused by snow and ice loads.

[0063] The following detailed description refers to the accompanying drawings, which form part of this description of the invention and illustrate specific embodiments with which the invention can be carried out. In this respect, directional terminology such as "top," "bottom," "front," "back," "anterior," "rear," etc., is used in relation to the orientations of the described figure(s). Since components of embodiments can be positioned in a number of different orientations, the directional terminology serves for illustration and is in no way limiting. It is understood that other embodiments may be used and structural or logical modifications may be made without deviating from the scope of protection of the present invention. The following detailed description is not to be interpreted in a limiting sense.

[0064] Within this description, the terms "connected," "attached," and "integrated" are used to describe both direct and indirect connections, direct or indirect links, and direct or indirect integrations. In the figures, identical or similar elements are marked with the same reference symbol where appropriate.

[0065] Reference lines are lines that connect the reference symbol to the relevant part. An arrow, on the other hand, that does not touch any part refers to the entire unit to which it points. Furthermore, the figures are not necessarily to scale. To illustrate details, certain areas may be exaggerated. In addition, the drawings may be simplified for clarity and do not include every detail that might be present in practical implementation. The terms "above" and "below" refer to the representation in the figures. Finally, for the sake of clarity, only one of several identical components or elements is marked with a reference symbol.

[0066] They show: Figure 1 shows an isometric cross-section of a pole-mounted luminaire designed according to the invention with a first embodiment of a stiffening insert; Figure 2 shows a bottom view of a pole-mounted luminaire housing with a first embodiment of a stiffening bracket according to the invention; and Figure 3 shows a view of the housing of the pole-mounted luminaire according to Figure 2 with a second embodiment of a stiffening bracket according to the invention. Figure 4 shows an isometric top view of the stiffening frame 4 according to the invention. Figure 1 Figure 5 shows an isometric interior view of an alternative design of the luminaire housing according to the Figures 2 and 3 without inserted stiffening bracket; Figure 6 an isometric top view of a stiffening bracket for use in the luminaire according to Figure 5 ; and Figure 7, an enlarged isometric interior view of the lamp according to Figure 5 with the inserted stiffening bracket according to Figure 6 in installed position.

[0067] Since these are initially the only relevant components for the present invention, only the luminaire housing with the mast connection and the stiffening structure arranged therein according to the invention are shown here. This means that the light source and other electrical components are not shown here for the sake of simplicity, but can of course be arranged within it.

[0068] According to Figure 1The first embodiment of a pole-mounted luminaire according to the invention, shown in isometric cross-section, consists of a funnel- or bowl-shaped luminaire housing 2 with a light emission opening 2a at the upper end shown in the figure, which can be closed by a cover plate (not shown). The luminaire housing 2 has a pole-mounted connector 2b molded in one piece at its base or lower end, which can be connected laterally to a pole (also not shown) via screw holes 2c. In this case, the luminaire housing is designed as a die-cast aluminum part. Figure 1 Reference numeral 16 indicates the area of ​​maximum voltage in the luminaire housing 2, i.e., the point with the highest voltage due to the design of the luminaire housing and the connection to the terminal piece.

[0069] A steel stiffening frame 4, designed to complement the geometry of the luminaire housing 2, can be inserted into the interior of the housing formed by the outer walls of the housing. In this case, the stiffening frame 4 comprises a fully enclosed upper frame 4a, extending parallel to the light emission opening 2a of the luminaire housing 2 when installed. Several rod-shaped struts 4b extend diagonally downwards from this upper frame to form a frame structure that is also essentially funnel-shaped in its outer contours. The frame elements or stiffening brackets are only present at the edges or corners, so that they rest against the inner edges or interior surfaces of the luminaire housing 2 when installed, thus providing stabilizing stiffening.Furthermore, on the left side of the figure, a continuous and arc-shaped stiffening plate 4c is formed, on the upper side of which several parallel stiffening ribs 4d are integrally formed in the direction of view for the particularly high loads in the connection area or joint area at the mast base or for a possible connection with the mast base stud 2b.

[0070] The Figure 2Figure 1 shows a bottom view of a pole-mounted outdoor light with a substantially elongated, bowl-shaped housing 6, which is closed at the top and has a light-emitting opening on its underside (visible in the direction of viewing). This opening has a circumferential inner rim 6a for a light cover. A pole mounting bracket 8 is screwed to the pole-mounting end of the housing 6 on the left side of the figure. A stiffening bracket 10 is attached to this bracket. The stiffening bracket 10 projects from the pole mounting bracket 8 into the interior of the housing 6 and rests against the top of the housing 6. The stiffening bracket 10 has two longitudinal struts 10a, 10b that extend to the top of the housing 6 and rest against its inner surface. These struts are connected to each other by a cross strut 10c to form a closed stiffening structure.On the inside of the luminaire housing 6, several mounting pins 6b (only one with a reference numeral) are provided for mounting or supporting the stiffening bracket 10. Different pairs of pins are located on both sides of the central longitudinal axis of the luminaire housing to accommodate stiffening brackets of different sizes and thus compensate for different loads.

[0071] The Figure 3 The light housing shows according to Figure 2 in a similar view with a differently designed stiffening bracket 12, which differs from the embodiment according to Figure 2This is distinguished by the fact that the longitudinal struts 12a, 12b project outwards to the inner edge of the luminaire housing 6, abut against the inner edge there, and are connected to each other again via a transverse strut 12c to form the stiffening bracket with a closed structure, which gives the stiffening bracket 12 particularly high stability. It is clearly recognizable that in the embodiments according to Figure 2 and 3 The stiffening brackets 10 and 12 are relatively delicate and small compared to the size of the luminaire housing. Nevertheless, these stiffening brackets almost double the wind load resistance of the mast-mounted luminaire.

[0072] Figure 4 shows an isometric top view of the luminaire housing 2 according to Figure 1usable stiffening frame 4 with the stiffening plate 4c arranged on the underside in the connecting piece with stiffening ribs 4d formed on it and struts 4b extending forward and upward from the curved stiffening plate 4c to form the stiffening structure, wherein the upper frame 4a then terminates flush with the light emission opening 2a of the luminaire housing 2.

[0073] Figure 5 shows the isometric interior view of an alternatively designed luminaire housing 6 according to the Figures 2 and 3 with unused stiffening brackets. In the connection area, several fixing ribs 6c, d, e are spaced apart from each other on the inside of the luminaire housing 6 to form insertion gaps into which the connecting end of the stiffening bracket 14 can be inserted.

[0074] This in Figure 7The stiffening bracket 14 shown in more detail is designed as a fully enclosed frame made of longitudinal struts 14a, b and transverse struts 14c, d, which also has spaced-apart insert projections 14e, f at the connection end for insertion into the insert spaces on the inside of the luminaire housing 6 according to Figure 4 exhibits.

[0075] Figure 7 shows an enlarged isometric top view of the connection end of the luminaire according to Figure 5 with inserted stiffening bracket according to Figure 6. Figure 7 then shows an enlarged isometric interior view of the light fixture according to the Figures 5 with the inserted stiffening bracket according to Figure 6It is clearly visible how the rear insertion projections 14 e, f engage positively in the fixing ribs 6c, d, e of the housing 6 at the connection end of the stiffening bracket 14 and how the front ends of the longitudinal struts 14a, b rest against the inside of the housing 6, supporting and thus stabilizing it.
