Description

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 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.

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.

In the DE 196 35 521 A1 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.

In the DE 10 2010 015 210 A1 a luminaire is described in which a frame carries the light roof and a screen formed of four panes is inserted into the frame.

In the US 2009/0154168 A1 is also described a lamp in which a frame carries the light roof.

From the prior art and especially from the European patent application EP 2 557 360 A1 is an attachment lamp for outdoor lighting known which uses LED modules as lighting arrangement. In order to ensure the desired beam direction down, the LED modules are connected via a block with a heat sink, which has a ribbed outer edge. This outer edge protrudes above the screen out of the attachment lamp. On the heat sink a cover is provided, which closes the attachment lamp upwards. It must be ensured both between shield and heat sink and between the heat sink and the cover effective sealing, especially because the transformer for the LED modules is located above the heat sink. To support this construction vertical support bars are provided outside the screen. Within the screen, a vertical pipe for electrical connection of the LED modules and other electrical components to the heat sink, in particular of the transformer, is provided.

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.

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 above object is achieved with respect to a top luminaire for outdoor lighting with the features of the preamble of claim 1 by the features of the characterizing part of claim 1.

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.

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.

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.

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.

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.

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 claims 9 and 10 and between the screen and lamp stand on the other hand by the preferred embodiments of claim 11. In this case, the claims 9 and 11 relate to corresponding advantageous embodiments of the screen with respect to its production.

Finally, the preferred embodiments of 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. In principle, 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. Also contemplated are other types of semiconductor based light emitting devices. Furthermore, the proposed attachment lamp comprises a light roof 4, which is arranged above the screen 2.

For 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. Preferably, the screen 2 carries the light roof 4 to at least 80% or in particular to 100% and thus alone. In other words, 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. This also applies to the weight of any further, attached to the light cover 4 devices, for which still examples are described below. 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. Here and preferably, the screen 2 is elongated and / or cylindrical.

According to the proposal, 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.

Since the electrical supply of the lighting arrangement 3 is regularly supplied by the light tower, the need for an electrical supply from the lamp base 1 to the light roof 4 can exist in particular when placing the lighting arrangement 3 on the light roof 4. According to the Fig. 1 and 2 For this purpose, it is preferred that 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. Preferably, 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 , It is also preferred that 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.

Advantageously, 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. In particular, 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. As shown in the drawing, 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.

Advantages for both the sealing and the heat dissipation arise when according to the preferred embodiment of the embodiment, the light roof 4 is integrally formed and an upper opening edge 8 of Screen 2 covers. Preferably, the cover of the upper opening edge 8 and / or the upper opening of the screen 2 takes place completely. In this way, 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. In the sense of a most effective heat dissipation, the base assembly 9 is here and preferably formed integrally with the light roof 4. For directed illumination of a desired area around the post-top luminaire, it is further advantageously provided that 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. In the exemplary embodiments of the drawing and as preferred, 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.

Regularly, it is desired to be able to attach a Aufsetzhaube 11 on the top lamp. This is in the Fig. 1 and 3 and was for clarity in the Fig. 2 omitted. The provision of the Aufsetzhaube 11 allows on the one hand a flexible aesthetic design and on the other hand, the arrangement of reflectors on the attachment hood 11, if necessary to be able to direct the lighting effect even more towards the floor. In the present embodiments, it is achieved both that the sealing of the post light is guaranteed regardless of the presence or the characteristics of the attachment hood 11 as well as causes the Aufsetzhaube 11 does not affect the heat dissipation through the light cover 4, but even promoted. This is preferably done by the light roof 4 hood fastening means 12, which are in particular hood attachment openings 12a, for the attachment hood 11 and a, in particular flat, roof surface 13 for heat transfer to the attachment hood 1 has.

In the present case and preferably, 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.

Furthermore, a particularly advantageous connection between the light roof 4 and 2 screen is possible if, as preferred here, 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.

In this context, 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.

These 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. For this purpose, the screen 2 preferably has a Fußwulst 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. As already described for the roof bead 14, it is analogously preferred here that 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 the Fußwulst 19, which may in particular be frictionally. It can, as shown in the drawing, take place by clamping the Fußwulstes 19 between the lamp base 1 and a Fußgegenfläche 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.

According to a preferred embodiment, which the second and third embodiments of the Fig. 4 or the Fig. 5 corresponds, the Fußgegenfläche 20 is formed by a Fußgegenring 21. This Fußgegenring 21 can according to the second embodiment of Fig. 5 have a top with a flat edge. Alternatively and as in the Fig. 6 illustrated for the third embodiment, the Fußgegenring 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. In the present exemplary embodiment, the drying space 23 is formed by the entire space enclosed by the lamp base 1, the screen 2 and the light roof 4. Preferably in this context and shown in the drawing is that the connection between the light roof 4 and roof bead 14 against the outside environment is sealing. Alternatively or additionally, and as also shown in the drawing, the connection between the lamp base 1 and foot bead 19 against the outside environment is sealing.

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 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.

Preferably, the inner housing 24 in its cavity 24 a - not shown here - electrical operating assembly for the light assembly 2. This may include, for example, a transformer for the power supply of the LED array 3a.

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 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 Fußwulstes 19 between the lamp base 1 and the Fußgegenfläche 20 and a lower surface 26 of the inner housing 24 is clamped to the lamp base 1.

As in the 4 to 6 illustrated, it is in these terminals preferably the same clamping connection with which the Fußwulst 19 is attached to the lamp base 1. Here, the first embodiment according to the Fig. 4 Particularly preferred because here the lower surface 26 of the inner housing 24 forms the Fußgegenfläche 20. This is a arranged below the screen 2 Fußgegenring 21 dispensable. Optionally, here as well - as in the Fig. 4 shown - in addition a housing ring 27 may be provided within the inner housing 24.

For the above terminals, 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. In such a case, the screen 2 can simply be placed on the lamp base 1 and the inner housing 24 can be inserted into the screen 2.
