Definitions
- the invention relates to a post light for outdoor lighting according to the preamble of claim 1.
- Such post-top luminaires are regularly used to illuminate public outdoor areas, such as streets, sidewalks, green areas or parking lots, as well as to illuminate private outdoor areas on land owned by businesses or private individuals. They are usually arranged at a suitable distance from the ground on a light pole. In this case, the emitted light from the top light should radiate basically in the direction of the ground, which in addition to a desired circular beam around the post light or the light pole around, depending on the application situation, lighting surfaces with other, in particular semicircular light cones may be desired.
- the said lamp posts are designed for a very long period of use of several decades, during which they are exposed to all occurring weather, over this period of use, the time of the actual luminous activity may also be long and may even be substantially 50% of the period of use, if namely, the top light should shine the whole time without sunlight. Furthermore, the post light should be able to be operated during this time as possible without failures or maintenance.
- a reliable sealing of the actual lighting arrangement against moisture and insects from the outside is an important consideration.
- a luminaire is described with a translucent screen, in which the screen is formed integrally with the light roof and thus carries the light roof.
- a luminaire in which a frame carries the light roof and a screen formed of four panes is inserted into the frame.
- the object of the invention is thus to improve a known from the prior art essay lamp so and further that both simplifies their construction and facilitates the achievement of the seal.
- the construction of the post light is simplified and reliable in different ways when previously distributed to individual components functions are bundled into fewer components and here especially the screen of the post light is also used to support the light roof. This approach allows a whole series of further simplifications.
- the lighting arrangement itself is also supported by the screen. In this way, a separate support structure for the lighting arrangement is unnecessary.
- the dependent claim 4 provides a now possible floating - and thus favorable - storage of a vertical pipe before, through which can be performed as electrical connections between the roof and foot area of the attachment lamp. This storage is floating so far that the conduit is not wearing.
- claims 6 to 8 relate to advantageous features of the luminous roof and the arrangement possibilities of the light assembly of the post-top luminaire on the light roof for effective heat dissipation through the light roof.
- claims 13 to 15 advantageous variants of an inner housing for receiving additional electrical components for the operation of the attachment lamp before.
- the in the Fig. 1 illustrated proposed post light is used for outdoor lighting and is therefore adapted to be mounted outside of buildings outdoors on a suitable mast or stand and used.
- the proposed attachment lamp comprises a lamp base 1 for attachment on a - not shown here - light pole, in principle, the attachment to another support arrangement with correspondingly similar contact design comes into consideration.
- the proposed attachment lamp further has a hollow, translucent screen 2 for placement on the lamp base 1 and arranged in the screen 2 electrical light assembly 3.
- the translucent screen 2 may be clear, but may equally be opaque and / or have opacities, tints, light-diffusing surface contours, or other features, in particular, to avoid dazzling, which does not preclude principal transparency.
- the lighting arrangement 3 can be any lighting arrangement which converts light into light into any lighting means, such as an incandescent lamp, a fluorescent tube, a metal vapor lamp or a combination of these lamps.
- the lighting arrangement 3 preferably comprises an LED (light-emitting diode) arrangement 3a.
- LED light-emitting diode
- the proposed attachment lamp comprises a light roof 4, which is arranged above the screen 2.
- the lamp base 1 and / or the light roof 4 a metal and in particular aluminum, an aluminum alloy or iron is preferably provided as material or essential component.
- the lamp base 1 and / or the light roof can also be made in the sand-molding process.
- the screen 2 preferably consists essentially of polymethylmethacrylate or polycarbonate.
- the proposed top luminaire is characterized in that the screen 2 carries the luminous roof 4.
- the screen 2 carries the light roof 4 to at least 80% or in particular to 100% and thus alone.
- the weight of the luminous roof 4 is absorbed by the screen 2 to at least 80% or in particular to 100% and thus completely.
- the screen 2 then transfers this weight in whole or in part to the lamp base 1. It follows that, if further devices are connected to both the light roof 4 and the lamp base 1, these each transmit no force from the light roof 4 to the lamp base 1, including an example will be described below.
- the screen 2 is elongated and / or cylindrical.
- the lighting arrangement 3 is arranged on the light roof 4, preferably completely, so that the lighting arrangement 3 is supported by the screen 2 next to the light roof 4. Especially is how out of the Fig. 1 and 2 recognizable, the light assembly 3 also attached to the light cover 4.
- the attachment lamp has a supply device 5 for an electrical line (not shown here) between the lamp base 1 and the light cover 4 and that the supply device 5 is mounted floating in the longitudinal direction of the screen 2.
- the feeding device 5 is a conduit 6.
- the floating mounting of the feeding device 5 allows generous tolerance and is made possible by the proposed wearing of the light roof 4 through the screen 2, since thereby the feeding device 5 does not have to absorb weight of another component ,
- the light roof 4 has a conduit opening 7 for guiding the supply device 5. It follows that the guide of the feeding device 5 is floating through the conduit opening 7.
- the screen 2 is integrally formed. This allows both a favorable production and a particularly effective seal between the screen 2 on the one hand and the lamp base 1 and / or the light roof 4 on the other.
- the screen 2 may be formed material homogeneous. This means that although the screen 2 may have been composed of individual components, at least after its formation no difference or transition between these former components is present or can be detected.
- the screen 2 must not only be purely cylindrical. In each case, the screen 2 shown in the drawing has, in addition to a cylindrical basic shape, further structures at its upper and lower edges, which will be discussed in greater detail below. Insbesonsdere the screen 2 can be formed by forming, so by a change in shape of an already shaped initial shape, and here especially by a particular bending hot forming.
- the light roof 4 is integrally formed and an upper opening edge 8 of Screen 2 covers.
- the cover of the upper opening edge 8 and / or the upper opening of the screen 2 takes place completely.
- the heat dissipation can be effectively ensured by the light roof 4 itself. It therefore eliminates the need to lead out another structure - such as a separate heat sink - still between the screen 2 and light cover 4 from the post light, which would inevitably complicate the effective seal.
- the luminous roof 4 preferably has a base arrangement 9 for fastening the luminous arrangement 3.
- the base assembly 9 is here and preferably formed integrally with the light roof 4.
- the base post 9 has at least one angled base surface 10 a, b for fastening the luminous arrangement 3. Angled here means that the base surface 10a, b is arranged neither perpendicular nor parallel to - vertical - solder, but at an angle between 0 ° and 90 ° to this.
- the attachment lamp has two, each axially symmetrically arranged angled base surfaces 10a, b, wherein according to the embodiment, the lighting assembly 3 is arranged only on the base surface 10a. It is also conceivable, however, a placement of the light assembly 3 on both base surfaces 10 a, b.
- the hood fastening means 12 are arranged radially projecting the screen 2, so that they do not influence the sealing of the attachment lamp in the case of the hood mounting openings 12a present here.
- These hood attachment openings 12a may then be approximately - as specifically in the Fig. 2 and 3 shown - used for screw connections.
- a particularly good heat transfer to the attachment hood 11 is achieved when the roof surface 13 completely an upper outer surface of the light roof 4, wherein the outer surface in this sense, a contact surface between the light roof 4 and the attachment hood 11 counts forms. In this case, therefore, a large-area contact between the light cover 4 and the attachment hood 11 can be produced.
- the screen 2 a roof bead 14 and in particular a - radially outwardly facing - flange has to fasten the light roof 4.
- This roof bead 14 may be integral with the Screen 2 is formed. It is preferably provided that the roof bead 14 is formed homogeneously with the screen 2-in the sense already described above-and in particular by hot forming of the screen 2. This hot forming of the screen 2 can be, above all, a bending hot forming.
- the above attachment is preferably carried out by a non-positive connection between the light roof 4 and roof bead 14, a connection, in which the light roof 4 is pressed against the roof bead 14. In the present case the details are from the Fig. 3 recognizable.
- a clamping of the roof bead 14 between the light roof 4 and a roof counter surface 15 is preferably provided for this connection between the light roof 4 and roof bead 14.
- This roof counter-surface 15 may be formed approximately by a roof counter-ring 16, which is arranged relative to the roof bead 14 opposite to the light roof 4.
- the light roof 4 preferably has roof fastening means 17, which are radially arranged the umbrella 2 - and thus also the roof bead 14 - outstanding. It may turn in these roof fastening means 17 openings for the implementation or attachment of z. B. screws, with which then the roof counter-surface 15 and the roof counter-ring 16 can be tightened to clamp the roof bead 14.
- roof fastening means 17 can also, as in the present case and as in the Fig. 3 shown to be at least partially or completely identical to the hood fasteners 12. Like from the Fig. 2 proceeding, are in the present embodiments, all hood fasteners 12 and roof fasteners 17, but not all roof fasteners 17 and hood fasteners 12. So, as again in the Fig. 3 shown, with a single screw connection screen 2, light cover 4 and 11 Aufsetzhaube connected to each other. Like also in the Fig. 3 Furthermore, a sealing means 18 between the light roof 4 and the roof bead 14 and / or between the roof counter-surface 16 and the roof bead 14 may be arranged.
- a connection between the screen 2 and lamp base 1 is made in the present embodiment in a similar manner as between the screen 2 and the light roof 3, which is described in more detail below and in the 4 to 6 is shown.
- the screen 2 preferably has a respectfulwulst 19 and in particular a ring-like inner lip - which therefore points radially inward - for attachment to the lamp base 1, which as further preferred and shown in the drawing is integrally formed with the screen 2.
- the foot bead 19 is formed in a material-homogeneous manner with the screen 2 and, in particular, by hot forming of the screen 2, which hot forming can advantageously be bendable.
- the above attachment is preferably carried out by a connection between the lamp base 1 and theticianwulst 19, which may in particular be frictionally. It can, as shown in the drawing, take place by clamping the contemplatwulstes 19 between the lamp base 1 and amonurgial 20. This clamping can in principle also be done by screw on substantially to the terminals of the roof bead 14 between the light roof 4 and the roof counter surface 15 mutatis mutandis the same way.
- the neutrophil configuration 20 is formed by a serving awakering 21.
- This approaching Vietnamesering 21 can according to the second embodiment of Fig. 5 have a top with a flat edge.
- the bossurgiring 21 also have an upstanding collar edge 22 for enclosing the screen 2.
- This embodiment is particularly suitable for providing a sealing means 18 between the foot bead 19 and the lamp base 1, on the one hand, and between the foot bead 19 and the foot counter surface 20, on the other hand.
- the post light regularly includes in addition to the light assembly 3 even more electrical or electronic components to be protected from the weather. Therefore, it is preferable that the lamp base 1, the screen 2 and the light cover 4 enclose a drying room 23 with respect to an outside environment of the attachment lamp. This drying space 23 is thus effectively sealed against the ingress of moisture from the outside environment.
- the drying space 23 is formed by the entire space enclosed by the lamp base 1, the screen 2 and the light roof 4.
- the connection between the light roof 4 and roof bead 14 against the outside environment is sealing.
- the connection between the lamp base 1 and foot bead 19 against the outside environment is sealing.
- the attachment lamp - as shown in the drawing - a sheathed by the screen 2 inner housing 24 having a cavity 25 for placement on the lamp base 1. If, as already described above, the attachment lamp has a drying space 23, then the inner housing 24 will be regularly arranged in this drying space 23. Without having to provide an additional seal especially for the inner housing 24, then the cavity 25 is also part of the drying space 23.
- the cavity 25 forms a receptacle, which both the necessary seal against the outside environment and the possibility of a simple Assembling offers, namely by simply inserting the inner housing 24 in the screen 2. Since the inner housing 24 is also opaque regularly, various components can be arranged here, without disturbing the aesthetic effect of the attachment lamp.
- This may include, for example, a transformer for the power supply of the LED array 3a.
- the attachment lamp can preferably also comprise a camera arrangement, a radio arrangement, in particular on RFID (radio-frequency identification) basis, a scaffoldleitan extract or other electrical or electronic component, which can be advantageously arranged in each case in the cavity 24.
- the electrical connection between the electrical operating arrangement and the lighting arrangement 3 or another device on the light roof 4 is then preferably produced by the above feeding device 5.
- the inner housing 24 can then be attached to the lamp base 1 in a particularly simple manner if, as preferred when clamping the contemplatwulstes 19 between the lamp base 1 and thelandaisussi thoughts 20 and a lower surface 26 of the inner housing 24 is clamped to the lamp base 1.
- the lamp base 1 preferably has foot fasteners 28 which, as shown, may be foot mounting holes which, as shown, may also be used for bolted connections to both Attachment of the screen 2 and for fixing the inner housing 24 can be used on the lamp base 1.
- the assembly of the attachment lamp is then easier if, as in the present embodiments, the inner housing 24 with the screen 2 at least partially forms a clearance fit.
- the screen 2 can simply be placed on the lamp base 1 and the inner housing 24 can be inserted into the screen 2.

Description
Die Erfindung betrifft eine Aufsatzleuchte zur Außenbeleuchtung gemäß dem Oberbegriff von Anspruch 1.The invention relates to a post light for outdoor lighting according to the preamble of
Derartige Aufsatzleuchten werden regelmäßig zur Beleuchtung sowohl öffentlicher Außenbereiche, zu denen etwa Straßen, Gehwegen, Grünanlagen oder Parkplätzen zählen, als auch zur Beleuchtung privater Außenbereiche auf Grundstücken von Unternehmen oder Privatpersonen eingesetzt. Sie werden in der Regel in passendem Abstand vom Grund auf einem Lichtmast angeordnet. Dabei soll das von der Aufsatzleuchte abgegebene Licht grundsätzlich in Richtung des Grundes abstrahlen, wobei neben einem angestrebten kreisförmigen Lichtkegel um die Aufsatzleuchte bzw. den Lichtmast herum auch, je nach Einsatzsituation, Beleuchtungsflächen mit anderen, insbesondere halbkreisförmigen Lichtkegeln gewünscht sein können.Such post-top luminaires are regularly used to illuminate public outdoor areas, such as streets, sidewalks, green areas or parking lots, as well as to illuminate private outdoor areas on land owned by businesses or private individuals. They are usually arranged at a suitable distance from the ground on a light pole. In this case, the emitted light from the top light should radiate basically in the direction of the ground, which in addition to a desired circular beam around the post light or the light pole around, depending on the application situation, lighting surfaces with other, in particular semicircular light cones may be desired.
Der prinzipielle Aufbau einer Aufsatzleuchte mit einem Leuchtenfuß, einem darauf angeordneten lichtdurchlässigen Schirm und einem abschließenden Leuchtendach ist schon von Gasleuchten bekannt und wurde seither im Wesentlichen bei fortschreitender Weiterentwicklung des jeweiligen Leuchtmittels der Leuchtanordnung und der sonstigen Technik im Grunde beibehalten.The basic structure of a post-top luminaire with a lamp base, a translucent screen arranged thereon and a final luminous roof is already known from gas lamps and has essentially been maintained since the further development of the respective luminous means of the luminous arrangement and the other technology.
Die besagten Aufsatzleuchten sind für einen sehr langen Einsatzzeitraum von mehreren Jahrzehnten, während welcher sie allen auftretenden Witterungen ausgesetzt sind, ausgelegt, wobei über diesen Einsatzzeitraum auch die Zeit der eigentlichen Leuchtaktivität ebenfalls lang sein kann und sogar im Wesentlichen 50% des Einsatzzeitraums betragen kann, wenn nämlich die Aufsatzleuchte die gesamte Zeit ohne Sonnenlicht leuchten soll. Ferner soll die Aufsatzleuchte in dieser Zeit möglichst ohne Ausfälle oder Wartungen betrieben werden können. Hier ist insbesondere eine zuverlässige Abdichtung der eigentlichen Leuchtanordnung gegenüber Feuchtigkeit und Insekten von außen ein wichtiger Gesichtspunkt.The said lamp posts are designed for a very long period of use of several decades, during which they are exposed to all occurring weather, over this period of use, the time of the actual luminous activity may also be long and may even be substantially 50% of the period of use, if namely, the top light should shine the whole time without sunlight. Furthermore, the post light should be able to be operated during this time as possible without failures or maintenance. Here, in particular, a reliable sealing of the actual lighting arrangement against moisture and insects from the outside is an important consideration.

Aus dem Stand der Technik und speziell aus der europäischen Patentanmeldung
Nachteilig an diesem Stand der Technik ist einerseits, dass die Konstruktion der Aufsatzleuchte kompliziert und durch die Vielzahl der Bauteile aufwendig ist. Einerseits gibt es verhältnismäßig viele Kontaktbereiche an der Außenhülle der Aufsatzleuchte, welche zum Schutz elektrischer Komponenten abgedichtet werden müssen. Schwächen der Dichtung an nur einer Stelle betreffen die Funktion der gesamten Aufsatzleuchte. Ferner sind vor allem die vertikalen Komponenten des Schirms, der Stützstäbe und des Rohrs zueinander vergleichsweise genau zu tolerieren, insbesondere auch um die genannte Dichtwirkung wirksam erreichen zu können.A disadvantage of this prior art, on the one hand, that the construction of the attachment lamp complicated and is complicated by the large number of components. On the one hand, there are relatively many contact areas on the outer shell of the post light, which must be sealed to protect electrical components. Weaknesses of the seal at only one point affect the function of the entire top luminaire. Furthermore, especially the vertical components of the screen, the support rods and the tube to each other to tolerate relatively accurate, especially in order to achieve the said sealing effect effectively.
Die Aufgabe der Erfindung besteht demnach darin, eine aus dem Stand der Technik bekannte Aufsatzleuchte so zu verbessern und weiterzuentwickeln, dass sowohl ihr Aufbau vereinfacht als auch das Erreichen der Abdichtung erleichtert wird.The object of the invention is thus to improve a known from the prior art essay lamp so and further that both simplifies their construction and facilitates the achievement of the seal.
Die obige Aufgabe wird bezogen auf eine Aufsatzleuchte zur Außenbeleuchtung mit den Merkmalen des Oberbegriffs von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.The above object is achieved with respect to a top luminaire for outdoor lighting with the features of the preamble of
Erfindungsgemäß ist erkannt worden, dass sich die Konstruktion der Aufsatzleuchte in verschiedener Hinsicht vereinfacht und zuverlässiger wird, wenn bisher auf jeweils einzelne Bauteile verteilte Funktionen in weniger Bauteilen gebündelt werden und hier speziell der Schirm der Aufsatzleuchte auch zum Tragen des Leuchtendachs verwendet wird. Dieser Ansatz ermöglicht eine ganze Reihe weiterer Vereinfachungen.According to the invention it has been recognized that the construction of the post light is simplified and reliable in different ways when previously distributed to individual components functions are bundled into fewer components and here especially the screen of the post light is also used to support the light roof. This approach allows a whole series of further simplifications.
Erfindungsgemäß wird auch die Leuchtanordnung selbst von dem Schirm getragen. Auf diese Weise wird auch eine separate Trageanordnung für die Leuchtanordnung entbehrlich.According to the invention, the lighting arrangement itself is also supported by the screen. In this way, a separate support structure for the lighting arrangement is unnecessary.
Der Unteranspruch 4 sieht eine nunmehr mögliche schwimmende - und damit günstige - Lagerung eines vertikalen Leitungsrohres vor, durch welches etwa elektrische Verbindungen zwischen dem Dach- und Fußbereich der Aufsatzleuchte geführt werden können. Diese Lagerung ist schwimmend auch insofern, dass dem Leitungsrohr keine Tragefunktion zukommt.The
Durch die bevorzugte Ausgestaltung nach dem Unteranspruch 5, welcher einen einstückigen Schirm vorsieht, werden die vorschlagsgemäßen Vorteile weiter verstärkt. So können auch zusätzliche Strukturen am Schirm vorgesehen sein, welche weitere konstruktive Möglichkeiten eröffnen, aber keine weitere Abdichtung erforderlich machen.The preferred embodiment according to the dependent claim 5, which provides a one-piece screen, the proposed advantages are further enhanced. Thus, additional structures can be provided on the screen, which open up further design options, but do not require further sealing.
Die bevorzugten Ausgestaltungen der Ansprüche 6 bis 8 betreffen vorteilhafte Merkmale des Leuchtendachs sowie der Anordnungsmöglichkeiten der Leuchtanordnung der Aufsatzleuchte an dem Leuchtendach zur effektiven Wärmeableitung durch das Leuchtendach.The preferred embodiments of claims 6 to 8 relate to advantageous features of the luminous roof and the arrangement possibilities of the light assembly of the post-top luminaire on the light roof for effective heat dissipation through the light roof.
Sowohl einfach herzustellende als auch wirksam abdichtende Verbindungsmöglichkeiten zwischen Schirm und Leuchtendach einerseits werden durch die bevorzugten Ausgestaltungen der Ansprüche 9 und 10 und zwischen Schirm und Leuchtenfuß andererseits durch die bevorzugten Ausgestaltungen des Anspruchs 11 beschrieben. Hierbei betreffen die Ansprüche 9 und 11 entsprechend vorteilhafte Ausgestaltungen des Schirms bezüglich seiner Herstellung.Both easy to manufacture and effective sealing connection possibilities between the screen and the light roof on the one hand are described by the preferred embodiments of
Schließlich stellen die bevorzugten Ausgestaltungen der Ansprüche 13 bis 15 vorteilhafte Varianten eines Innengehäuses zur Aufnahme von weiteren elektrischen Bauteilen für den Betrieb der Aufsatzleuchte vor.Finally, the preferred embodiments of

Der Leuchtenfuß 1 und/oder das Leuchtendach kann auch im Sandformverfahren hergestellt werden. Der Schirm 2 besteht vorzugsweise im Wesentlichen aus Polymethylmethacrylat oder Polykarbonat.For the
Die vorschlagsgemäße Aufsatzleuchte ist dadurch gekennzeichnet, dass der Schirm 2 das Leuchtendach 4 trägt. Bevorzugt trägt der Schirm 2 das Leuchtendach 4 zu mindestens 80 % oder insbesondere zu 100 % und damit alleine. Mit anderen Worten wird die Gewichtskraft des Leuchtendachs 4 durch den Schirm 2 zu mindestens 80 % oder insbesondere zu 100 % und damit vollständig aufgenommen. Dies gilt auch für die Gewichtskraft etwaiger weiterer, an dem Leuchtendach 4 befestigter Vorrichtungen, wofür nachfolgend noch Beispiele beschrieben werden. Der Schirm 2 überträgt diese Gewichtskraft dann ganz oder teilweise auf den Leuchtenfuß 1. Es folgt, dass sofern weitere Vorrichtungen sowohl mit dem Leuchtendach 4 als auch mit dem Leuchtenfuß 1 verbunden sind, diese jeweils keine Kraft von dem Leuchtendach 4 an den Leuchtenfuß 1 übertragen, wozu ebenfalls untenstehend ein Beispiel beschrieben wird. Hier und bevorzugt ist der Schirm 2 länglich und/oder zylindrisch ausgebildet.The proposed top luminaire is characterized in that the
Vorschlagsgemäß ist die Leuchtanordnung 3 an dem Leuchtendach 4, und zwar vorzugsweise vollständig, angeordnet, sodass die Leuchtanordnung 3 - neben dem Leuchtendach 4 - von dem Schirm 2 getragen wird. Speziell ist, wie aus den
Da die elektrische Versorgung der Leuchtanordnung 3 regelmäßig durch den Lichtmast zugeführt wird, kann insbesondere bei der Platzierung der Leuchtanordnung 3 an dem Leuchtendach 4 der Bedarf nach einer elektrischen Zuführung von dem Leuchtenfuß 1 an das Leuchtendach 4 bestehen. Gemäß den
Vorteilhafterweise ist der Schirm 2 einstückig ausgebildet. Dies ermöglicht sowohl eine günstige Herstellung als auch eine besonders wirksame Abdichtung zwischen dem Schirm 2 einerseits und dem Leuchtenfuß 1 und/oder dem Leuchtendach 4 andererseits. Insbesondere kann der Schirm 2 materialhomogen ausgebildet sein. Das bedeutet, dass wenn auch der Schirm 2 möglicherweise aus einzelnen Bestandteilen zusammengesetzt wurde, jedenfalls nach seiner Ausformung kein Unterschied oder Übergang zwischen diesen vormaligen Bestandteilen mehr vorhanden ist bzw. erfasst werden kann. Wie in der Zeichnung dargestellt, muss der Schirm 2 nicht nur rein zylinderförmig sein. Der in der Zeichnung jeweils dargestellte Schirm 2 weist nämlich neben einer zylindrischen Grundform noch weitere Strukturen an seinen oberen und unteren Rand auf, auf welche nachfolgend noch genauer eingegangen wird. Insbesonsdere kann der Schirm 2 durch ein Umformen, also durch eine Formveränderung einer bereits geformten Ausgangsform, und hier vor allem durch eine insbesondere biegende Warmumformung geformt sein.Advantageously, the
Vorteile sowohl für die Abdichtung als auch für die Wärmeableitung ergeben sich, wenn gemäß der bevorzugten Ausgestaltung des Ausführungsbeispiels das Leuchtendach 4 einstückig ausgebildet ist und einen oberen Öffnungsrand 8 des Schirms 2 abdeckt. Vorzugsweise erfolgt die Abdeckung des oberen Öffnungsrands 8 und/oder der oberen Öffnung des Schirms 2 dabei vollständig. Auf diese Weise kann die Wärmeableitung wirksam von dem Leuchtendach 4 selbst gewährleistet werden. Es entfällt also die Notwendigkeit, eine sonstige Struktur - wie etwa einen separaten Wärmeableiter - noch zwischen Schirm 2 und Leuchtendach 4 aus der Aufsatzleuchte herauszuführen, was zwangsläufig die wirksame Abdichtung verkomplizieren würde.Advantages for both the sealing and the heat dissipation arise when according to the preferred embodiment of the embodiment, the
Bevorzugt weist das Leuchtendach 4 eine Sockelanordnung 9 zur Befestigung der Leuchtanordnung 3 auf. Im Sinne einer möglichst wirksamen Wärmeabführung ist die Sockelanordnung 9 hier und vorzugsweise einstückig mit dem Leuchtendach 4 ausgebildet. Zur gerichteten Beleuchtung eines gewünschten Bereichs um die Aufsatzleuchte herum ist weiter vorteilhafterweise vorgesehen, dass die Sockelanordnung 9 mindestens eine winklige Sockelfläche 10a, b zur Befestigung der Leuchtanordnung 3 aufweist. Winklig bedeutet hier, dass die Sockelfläche 10a, b weder senkrecht noch parallel zum - vertikalen - Lot, sondern in einem Winkel zwischen 0° und 90° zu diesem angeordnet ist. In den Ausführungsbeispielen der Zeichnung und wie bevorzugt weist die Aufsatzleuchte zwei, jeweils achsensymmetrisch angeordnete winklige Sockelflächen 10a, b auf, wobei gemäß dem Ausführungsbeispiel die Leuchtanordnung 3 nur auf der Sockelfläche 10a angeordnet ist. Denkbar ist aber auch eine Platzierung der Leuchtanordnung 3 auf beiden Sockelflächen 10a, b.The
Regelmäßig ist es gewünscht, eine Aufsetzhaube 11 auf der Aufsatzleuchte anbringen zu können. Diese ist in den
Vorliegend und bevorzugt sind die Haubenbefestigungsmittel 12 radial den Schirm 2 überragend angeordnet, sodass sie im Falle der hier vorliegenden Haubenbefestigungsöffnungen 12a die Abdichtung der Aufsatzleuchte nicht beeinflussen. Diese Haubenbefestigungsöffnungen 12a können dann etwa - wie speziell in den
Ferner ist eine besonders vorteilhafte Verbindung zwischen Leuchtendach 4 und Schirm 2 möglich, wenn, wie hier bevorzugt, der Schirm 2 einen Dachwulst 14 und insbesondere einen - radial nach außen weisenden - Flansch aufweist zur Befestigung des Leuchtendachs 4. Dieser Dachwulst 14 kann einstückig mit dem Schirm 2 ausgebildet. Bevorzugt ist vorgesehen, dass der Dachwulst 14 materialhomogen mit dem Schirm 2 - im oben bereits beschriebenen Sinne - und insbesondere durch eine Warmumformung des Schirms 2 gebildet ist. Diese Warmumformung des Schirms 2 kann vor allem eine biegende Warmumformung sein. Die obige Befestigung erfolgt bevorzugt durch eine kraftschlüssige Verbindung zwischen Leuchtendach 4 und Dachwulst 14, einer Verbindung also, bei der das Leuchtendach 4 an den Dachwulst 14 gedrückt wird. Vorliegend sind die Details hierzu aus der
In diesem Zusammenhang ist für diese Verbindung zwischen Leuchtendach 4 und Dachwulst 14 bevorzugt ein Klemmen des Dachwulstes 14 zwischen dem Leuchtendach 4 und einer Dachgegenfläche 15 vorgesehen. Diese Dachgegenfläche 15 kann etwa durch einen Dachgegenring 16 gebildet werden, welcher bezogen auf den Dachwulst 14 gegenüberliegend zum Leuchtendach 4 angeordnet ist. Das Leuchtendach 4 weist bevorzugt Dachbefestigungsmittel 17 auf, welche radial den Schirm 2 - und damit auch den Dachwulst 14 - überragend angeordnet sind. Es kann sich bei diesen Dachbefestigungsmitteln 17 wiederum um Öffnungen zur Durchführung oder Befestigung von z. B. Schrauben handeln, mit denen dann die Dachgegenfläche 15 bzw. der Dachgegenring 16 zum Klemmen des Dachwulstes 14 angezogen werden kann.In this context, a clamping of the
Diese Dachbefestigungsmittel 17 können auch, wie im vorliegenden Fall und wie in der
Eine Verbindung zwischen Schirm 2 und Leuchtenfuß 1 wird in dem vorliegenden Ausführungsbeispiel auf ähnliche Weise wie zwischen dem Schirm 2 und dem Leuchtendach 3 hergestellt, was nachfolgend genauer beschrieben und in den
Die obige Befestigung erfolgt vorzugsweise durch eine Verbindung zwischen dem Leuchtenfuß 1 und dem Fußwulst 19, welche insbesondere kraftschlüssig sein kann. Sie kann, wie in der Zeichnung gezeigt, durch ein Klemmen des Fußwulstes 19 zwischen dem Leuchtenfuß 1 und einer Fußgegenfläche 20 erfolgen. Dieses Klemmen kann prinzipiell auch durch Schraubverbindungen auf im Wesentlichen zu dem Klemmen des Dachwulstes 14 zwischen dem Leuchtendach 4 und der Dachgegenfläche 15 sinngemäß gleiche Weise erfolgen.The above attachment is preferably carried out by a connection between the
Gemäß einer bevorzugten Ausführungsform, welche dem zweiten und dritten Ausführungsbeispiel der
Die Aufsatzleuchte umfasst regelmäßig neben der Leuchtanordnung 3 noch weitere elektrische oder elektronische Komponenten, welche vor der Witterung geschützt werden sollen. Daher ist es bevorzugt, dass der Leuchtenfuß 1, der Schirm 2 und das Leuchtendach 4 einen Trockenraum 23 gegenüber einer Außenumgebung der Aufsatzleuchte umschließen. Dieser Trockenraum 23 ist also gegen das Eindringen von Feuchtigkeit aus der Außenumgebung wirksam abgedichtet. Im vorliegenden Ausführungsbeispiel wird der Trockenraum 23 durch den gesamten, von dem Leuchtenfuß 1, dem Schirm 2 und dem Leuchtendach 4 umschlossenen Raum gebildet. Bevorzugt in diesem Zusammenhang und in der Zeichnung dargestellt ist, dass die Verbindung zwischen Leuchtendach 4 und Dachwulst 14 gegenüber der Außenumgebung abdichtend ist. Alternativ oder zusätzlich und wie ebenfalls in der Zeichnung dargestellt ist auch die Verbindung zwischen Leuchtenfuß 1 und Fußwulst 19 gegenüber der Außenumgebung abdichtend.The post light regularly includes in addition to the light assembly 3 even more electrical or electronic components to be protected from the weather. Therefore, it is preferable that the
Insbesondere zur Aufnahme der oben genannten elektrischen oder elektronischen Komponenten ist es bevorzugt, dass die Aufsatzleuchte - wie in der Zeichnung gezeigt - ein von dem Schirm 2 ummanteltes Innengehäuse 24 mit einem Hohlraum 25 zur Anordnung auf dem Leuchtenfuß 1 aufweist. Wenn, wie bereits oben beschrieben, die Aufsatzleuchte einen Trockenraum 23 aufweist, dann wird regelmäßig das Innengehäuse 24 in diesem Trockenraum 23 angeordnet sein. Ohne eine zusätzliche Abdichtung speziell für das Innengehäuse 24 vorsehen zu müssen, ist dann auch der Hohlraum 25 Teil des Trockenraums 23. Der Hohlraum 25 bildet eine Aufnahmemöglichkeit, welche sowohl die notwendige Abdichtung gegenüber der Außenumgebung als auch die Möglichkeit eines einfachen Zusammenbaus bietet, nämlich durch einfaches Einführen des Innengehäuses 24 in den Schirm 2. Da das Innengehäuse 24 regelmäßig auch undurchsichtig ist, können hier auch verschiedene Komponenten angeordnet werden, ohne die ästhetische Wirkung der Aufsatzleuchte zu stören.In particular, for receiving the above-mentioned electrical or electronic components, it is preferred that the attachment lamp - as shown in the drawing - a sheathed by the
Vorzugsweise weist das Innengehäuse 24 in seinem Hohlraum 24 eine - hier nicht dargestellte - elektrische Betriebsanordnung für die Leuchtanordnung 2 auf. Hierzu kann etwa ein Transformator für die Stromversorgung der LED-Anordnung 3a zählen.Preferably, the
Neben dieser elektrischen Betriebsanordnung kann die Aufsatzleuchte bevorzugt auch eine Kameraanordnung, eine Funkanordnung, insbesondere auf RFID (radio-frequency identification) -Basis, eine Verkehrsleitanordnung oder eine andere elektrische oder elektronische Komponente umfassen, welche vorteilhafterweise jeweils in dem Hohlraum 24 angeordnet sein kann. Die elektrische Verbindung zwischen der elektrischen Betriebsanordnung und der Leuchtanordnung 3 oder einer sonstigen Vorrichtung am Leuchtendach 4 wird dann bevorzugt durch die obige Zuführvorrichtung 5 hergestellt.In addition to this electrical operating arrangement, the attachment lamp can preferably also comprise a camera arrangement, a radio arrangement, in particular on RFID (radio-frequency identification) basis, a Verkehrsleitanordnung or other electrical or electronic component, which can be advantageously arranged in each case in the
Das Innengehäuse 24 kann dann besonders einfach an dem Leuchtenfuß 1 befestigt werden, wenn wie bevorzugt beim Klemmen des Fußwulstes 19 zwischen dem Leuchtenfuß 1 und der Fußgegenfläche 20 auch eine Unterfläche 26 des Innengehäuses 24 an den Leuchtenfuß 1 geklemmt wird.The
Wie in den
Für das obige Klemmen weist der Leuchtenfuß 1 bevorzugt Fußbefestigungsmittel 28 auf, bei denen es sich wie gezeigt um Fußbefestigungsöffnungen handeln kann, welche dann ebenfalls wie gezeigt für Schraubverbindungen sowohl zur Befestigung des Schirms 2 als auch zur Befestigung des Innengehäuses 24 an dem Leuchtenfuß 1 verwendet werden können.For the above terminals, the
Der Zusammenbau der Aufsatzleuchte wird dann einfacher, wenn wie in den vorliegenden Ausführungsbeispielen das Innengehäuse 24 mit dem Schirm 2 zumindest abschnittsweise eine Spielpassung bildet. In so einem Fall kann einfach der Schirm 2 auf den Leuchtenfuß 1 gesetzt und das Innengehäuse 24 in den Schirm 2 eingeführt werden.The assembly of the attachment lamp is then easier if, as in the present embodiments, the
