Description

The invention relates to a lighting device for the outside area, in particular a spherical lamp, for use on soft surfaces.

The subject matter of the invention is defined in the appended claims.

Lighting devices for the outside area, for example for illuminating garden areas or terraces, are known from the prior art. Particularly high demands are regularly placed on such lighting devices, particularly with regard to weather resistance. To this extent, there is often a conflict of objectives between the optical effect of the lighting devices and the lighting properties, which are determined in particular by the proportion of transparent and translucent elements, and the weather resistance. With regard to weather resistance, the aspect of protecting regularly sensitive electronics from moisture is particularly important.

A known type of lighting devices for outdoor use are the so-called spherical lights. These spherical lights are base elements with a socket for receiving illuminants, which are inserted into the receiving opening of a hollow, spherical housing body in order to close it and to form a closed interior space inside the hollow housing body. Corresponding lighting devices for the outside area are not only perceived as being particularly visually appealing, but are also particularly robust because of the simple structure and the smooth surface, which offers little surface to attack. In addition, the covering, one-piece housing body in these lighting systems usually makes it particularly easy to reliably protect the electronics arranged in the base element from moisture and other weather conditions.

Despite these advantages, the spherical lights known in the prior art for outdoor use are also perceived as disadvantageous in many respects. In particular, it is regularly felt to be particularly disadvantageous that the mostly very voluminous, rigid housing bodies are very difficult to store and transport. Due to the shape of the hollow round balls, the maximum achievable packing density is greatly reduced and there is a large volume requirement. This is particularly true when corresponding lighting devices for sale are packaged in the usual way, for example in cardboard boxes, a comparatively large amount of packaging material being required in addition.

In addition, it is regularly perceived as a disadvantage that the hollow housing bodies, which are mostly made of plastic, are comparatively laborious to manufacture in conventional plastic-processing methods due to their shape as a hollow sphere, whereby manufacturing errors can easily arise in the interior of the hollow housing bodies, which are subsequently carried out in a visual quality check are more difficult to identify because of the largely closed shape of the hollow housing body.

In addition, lighting devices for outdoor areas are known from the prior art which, due to the relatively large cross-sectional area and due to insufficient attachment to the ground, run the risk of being unintentionally carried away in strong winds and thus possibly becoming a source of danger.

It was an object of the present invention to eliminate or at least mitigate the disadvantages of the prior art described above.

In particular, it was the object of the present invention to provide a lighting device for the outside area, which can be manufactured in a more time-efficient and cost-effective manner, is easier to check for production errors and, in particular, can be stored and easily transported in a particularly space-saving manner.

It was a desirable stipulation that the lighting device to be specified for the outdoor area is comparable to conventional lighting devices with regard to weather resistance and, ideally, should even show an improvement over them. The weather resistance should be at least so good that it can remain outside all year round even in the cold-temperate or cool-temperate climate zones.

In addition, it was a supplementary object of the present invention that the lighting device to be specified for the outside area can be designed to be particularly robust.

In this respect, it was desirable that the lighting device to be specified can be assembled simply, quickly and reliably even by laypeople, with no special tool being required, desirably.

An additional object of the present invention was that the lighting device for the outside area should be designed particularly well for use on soft surfaces and, in particular, should remain reliably and securely in the intended position even in challenging wind conditions.

The inventors of the present invention have now recognized that the above-described objects can be achieved if the hollow housing body of a lighting device is designed in a special manner in several parts, in that it is composed of at least a first and a second housing segment, for example two hemispheres, with a view to the lighting performance it is essential that both the first housing segment and the second housing segment are at least partially transparent or translucent.

The multi-part design of the hollow housing body makes it possible to considerably reduce the space required by the lighting device during storage and transport. In particular, it is possible in this way to design the housing segments of the housing body in such a way that they can be placed one inside the other during storage in order to minimize the storage volume. For example, a corresponding spherical lamp can be divided into two essentially equally large half-shells, which can be placed one inside the other, with the half-shells also advantageously being able to form a receptacle for the base element.

The person skilled in the art recognizes the great advantage of such a configuration, in particular with a view to the manufacturability of the required parts. It is generally easier to manufacture open elements, such as half-shells, using conventional plastic processing methods, in particular in comparison with otherwise largely closed hollow housing bodies which only have a small opening. It has proven to be particularly advantageous here that the resulting open housing segments can be examined for any manufacturing errors significantly more easily with a simple visual inspection.

Another advantage of this embodiment has been shown that in the event of defects or damage to the housing body, it is sufficient to only replace the affected housing segment, so that the entire housing body does not have to be replaced.

The inventors of the present invention have tried to identify a way how the advantageous multi-part construction of the hollow housing body can be realized without the weather resistance of the lighting device for the outdoor area being adversely affected, especially in cold-temperate and cool-temperate climates.

In many of the possible ways in which the housing segments can be connected, the weather resistance is often inadequate. In particular, the gluing of the housing segments is felt to be unsuitable in the light of the effects of solar radiation and the temperature fluctuations in the outside area.

Many mechanical connection methods, such as the provision of screw threads or any rotary locks, such as bayonet locks, have also not proven to be sufficiently stable on their own.

The inventors of the present invention have now recognized that, in addition to the housing segments, a connection frame must be provided which is connected or connectable to the first housing segment and the second housing segment in a reversible and non-destructively releasable manner via positive locking and / or frictional locking.

First of all, it was found that the use of this connection frame enables a weather-resistant connection of the housing segments if this is combined with the other connection methods described above, for example the mechanical connection, the combination resulting in particularly robust lighting devices.

In the course of further optimization, however, the inventors have recognized that through the use of the connection frame and the positive and / or non-positive connection with the housing segments produced via it, a housing body can be obtained that meets the requirements for weather resistance and without additional connecting means fulfills the robustness and which can advantageously be assembled and disassembled again particularly easily without the need to separate further connections between the housing segments, as occur, for example, when bonding. Correspondingly, such a lighting device, for example when the lighting design in the garden is changed, can be particularly easily assembled and disassembled or easily stored in the disassembled state.

It has proven to be a particular advantage of this embodiment that the resulting lighting devices are perceived as particularly pleasant and uniform Can have lighting effect. In the case of mechanical fasteners, such as screw threads, the structural elements provided for connection, for example the different material thicknesses and interfaces of a screw thread or adhesive protrusions, can be recognized during operation, which is perceived as disadvantageous. The use of a corresponding connection frame eliminates this problem, especially if the connection frame is made opaque, so that the technical effect as a connection element recedes during operation and the connection frame appears instead as a design element in the external view, which conceals any other connection elements.

The above-mentioned objects are correspondingly achieved by a lighting device for outdoor areas as defined in the claims. Preferred embodiments according to the invention emerge from the subclaims and the following statements.

Such features of lighting devices according to the invention, which are designated as preferred below, are combined in particularly preferred embodiments with other features designated as preferred. Combinations of two or more of the embodiments described below as particularly preferred are thus very particularly preferred. Embodiments are also preferred in which a feature that is designated as preferred to any extent is combined with one or more further features that are designated as preferred to any extent.

• - ein Sockelelement mit einer Fassung zur Aufnahme von Leuchtmitteln, und
• - einen hohlen Gehäusekörper mit einer Aufnahmeöffnung in der Außenwand, die dazu eingerichtet ist, das Sockelelement aufzunehmen, so dass das Sockelelement die Aufnahmeöffnung verschließt und im Inneren des hohlen Gehäusekörpers ein geschlossener Innenraum gebildet wird,

wobei der hohle Gehäusekörper ein erstes Gehäusesegment, ein zweites Gehäusesegment und einen Verbindungsrahmen umfasst, wobei das erste Gehäusesegment und das zweite Gehäusesegment, zumindest teilweise transparent oder transluzent sind,
wobei der Verbindungsrahmen reversibel und zerstörungsfrei lösbar über Formschluss und/oder Kraftschluss mit dem ersten Gehäusesegment und dem zweiten Gehäusesegment verbunden oder verbindbar ist.The invention relates to a lighting device for outdoor use, in particular a spherical lamp for use on soft surfaces, comprising:

• - A base element with a socket for receiving light sources, and
• a hollow housing body with a receiving opening in the outer wall, which is designed to receive the base element, so that the base element closes the receiving opening and a closed interior is formed inside the hollow housing body,

wherein the hollow housing body comprises a first housing segment, a second housing segment and a connecting frame, wherein the first housing segment and the second housing segment are at least partially transparent or translucent,
wherein the connecting frame is connected or connectable to the first housing segment and the second housing segment in a reversible and non-destructive releasable manner via a form fit and / or force fit.

The lighting device according to the invention is suitable for outdoor use, which in particular implies adequate weather resistance and impermeability. It is clear to the person skilled in the art that the majority of the lighting devices offered for indoor use, in particular ceiling lights and floor lamps, are generally not suitable for outdoor use.

The lighting device according to the invention comprises at least one base element, so that several base elements can also be present. Each base element comprises at least one socket for receiving illuminants into which the illuminants provided are inserted for later operation.

Like the lighting devices for the outside area known from the prior art, the lighting device according to the invention also comprises a hollow housing body. So that the lighting means can illuminate the hollow housing body from the inside during operation, the hollow housing body comprises a receiving opening into which the base element can be received, so that the lighting means to be arranged in the socket are located inside the hollow housing body.

With a view to weather resistance, it is necessary here for the base element to close the receiving opening at least partially, preferably essentially completely. As a result, analogous to the lighting devices known from the prior art, a closed interior space is formed in the interior of the hollow housing body.

According to the invention, the hollow housing body is not made in one piece, but consists of a first and a second housing segment, both of which are transparent or translucent, wherein the housing segments can be transparent or translucent independently of one another. A transparent housing segment is transparent and in this respect reveals, for example, the socket and the illuminant from the outside. Translucent housing segments, on the other hand, are permeable to radiation, but not transparent, for example because the light is heavily scattered. Examples of translucent materials are wax or milk glass.

According to the invention, the hollow housing body also comprises a connecting frame which is provided to connect the first and second housing segments to one another in a reversible and non-destructive releasable manner by using a shape and / or frictional connection of both segments with the connecting frame is generated. In accordance with the expert understanding, the expression “connecting frame” describes a, preferably uninterrupted, circumferential element which comprises an empty interior space, for example in the form of a connecting ring or a cuff.

According to the invention, the first housing segment and the second housing segment are reversibly and non-destructively releasably connected or connectable to the connecting frame via a form fit and / or force fit. In accordance with the expert understanding, this means that the lighting device according to the invention can be present both as a system of individual parts and in a partially or fully assembled state.

In principle, a lighting device according to the invention is preferred, the lighting device being designed such that the closed interior space is closed moisture-tight, in particular rain-tight, when the base element is arranged in the receiving opening.

In principle, all types of light sources are suitable, with incandescent lamps or LED lights being preferred for most applications. Accordingly, a lighting device according to the invention is preferred, the base element comprising a socket for receiving incandescent lamps or LED lights.

Due to the high weather resistance that can advantageously be achieved with the lighting devices according to the invention, in particular the secure closure of the interior against moisture, it is also possible to provide more sensitive electronic devices in the base element of the lighting device. A lighting device according to the invention is therefore preferred, the base element comprising an electrical control device, the electrical control device preferably being set up to control, preferably continuously, a lighting means arranged in the socket. A lighting device according to the invention is also preferred, the base element comprising electrical connection means for electrically connecting the lighting device to an energy source.

In principle, lighting devices according to the invention can be designed in various ways. In view of the susceptibility to strong winds, however, it is advantageous if the lighting device according to the invention is designed with a low center of gravity, which can advantageously be achieved in that the base body of the base element not only closes the receiving opening, but also directly on the opposite side Forms stand. A lighting device according to the invention is consequently preferred, the base element comprising a plate-shaped, in particular disk-shaped, base body which is designed such that it covers the receiving opening when the base element is arranged in the receiving opening, the socket preferably being arranged on the base body, with the base body being the side of the base body facing away from the socket is particularly preferably designed as a flat standing surface.

In order to additionally or alternatively achieve improved wind resistance, it has proven to be particularly advantageous to provide means for anchoring the base element in a soft substrate on the base element. This can be done in particular by a peg-like projection with which the base element can be driven into the ground. Alternatively, however, it is also conceivable to provide recesses on the base element in which, for example, pegs or similar anchoring means can be used. In summary, a lighting device according to the invention is preferred, the base element comprising means for anchoring the base element in a soft subsoil, in particular in the ground, the base element preferably comprising a tapering projection, which is particularly preferably designed as a tapering wedge or peg.

In principle, it is possible for the connection between the base element and the hollow housing body to take place exclusively in that the housing body is pressed onto the base element by its own weight. Such a configuration can be preferred, in particular, for weather-protected outdoor areas, because the lighting means can be exchanged particularly easily in corresponding lighting devices. However, for all weather-technically demanding applications it is clearly preferred if the base element and the housing body can additionally be connected by suitable means, a watertight connection being particularly preferred. A lighting device according to the invention is therefore preferred, the base element comprising means for connecting the base element to the hollow housing body, the means for connecting the base element to the hollow housing body preferably comprising a screw thread and the means for connecting the base element to the hollow housing body preferably being are arranged on the same side of the plate-shaped base body as the socket. Similarly, a lighting device according to the invention is preferred, the hollow housing body in the area of Receiving opening comprises means for connecting the hollow housing body to the base element, the means for connecting the hollow housing body to the base element preferably being formed by a projection surrounding the receiving opening at least partially, preferably completely, the projection particularly preferably comprising a screw thread.

Even if it is basically possible to implement the lighting device according to the invention in different variants, the spherical lamp is the shape of the lighting device in which the advantages described above are particularly evident. In this embodiment, the housing segments can in particular be designed as half-shells, which is not only particularly simple in terms of manufacture, but also leads to a particularly large amount of space during storage and to particularly stable housing bodies. A lighting device according to the invention is therefore preferred, wherein the outer contour of the hollow housing body at least partially corresponds to a sphere, and / or wherein the outer contour of the hollow housing body in the projection at least partially corresponds to a circle. A lighting device according to the invention is also preferred, the first housing segment and the second housing segment being designed as hollow half-shells, one of the housing segments being flattened by the receiving opening arranged in the outer wall and / or having a projection on the receiving opening.

It can be seen as a great advantage of the present invention that in addition to the first and second housing segments, further housing segments can also be provided, whereby in this preferred embodiment at least one further connecting frame must be provided for each further housing segment, so that n-1 Connection frame are present. The great advantage of such a configuration is that the use of space during storage can be optimized further and further in that each individual segment can be designed with a lower height, with the segments being able to be stored one inside the other. In addition, the great advantage of the lighting device according to the invention is to be seen in the fact that it can be expanded and supplemented in a modular manner in that further housing segments and connecting frames can be provided. For example, it is possible to convert a spherical lamp with only two housing segments in the design by inserting a further housing segment between the half-shells, which is now connected to the previously existing housing segments via two connecting frames. This makes it possible to arrive at modular lighting devices and, for example, to produce design variations for the lighting devices according to the invention with minimal effort. In the light of these explanations, a lighting device according to the invention is preferred, wherein the hollow housing body comprises, in addition to the first housing segment, the second housing segment and the connecting frame, one or more further housing segments and a corresponding number of additional connecting frames, the additional connecting frame or frames each being reversibly and non-destructively detachable Form fit and / or force fit with the further housing segment and another housing segment of the hollow housing body are connected or connectable.

Regardless of the above, with a view to the simple production and in particular the simple assembly of the device, in particular by laypersons, as well as the robustness of the lighting device obtained, it is particularly preferred if the hollow lighting fixture consists of only two housing segments that are connected by a corresponding connecting frame or are connectable. Accordingly, a lighting device according to the invention is particularly preferred, the hollow housing body consisting of the first housing segment, the second housing segment and the connecting frame.

With a view to the later application, it is preferred if the lighting device according to the invention emits radiation that is as uniform as possible in all spatial directions and ideally has only a small variance in the radiation intensity at different sections of the housing body during operation. For this reason, it is particularly preferred if there are no obstacles inside the hollow housing body which could lead to unwanted shadows and which could reduce the radiation power in areas of the outer surface of the lighting device by interrupting the beam path. In this respect, it is particularly advantageous if the connecting frame is designed in such a way that, in the connected state, it does not or only slightly protrudes into the interior of the hollow housing body. A lighting device according to the invention is therefore preferred, with only a single closed interior space being formed inside the hollow housing body, the shape of which essentially corresponds to the outer shape of the outer wall, so that the shape of the interior space is preferably the outer shape of the hollow housing body minus the material thickness the outer wall results. Against this background, a lighting device according to the invention is also preferred, the connecting frame in FIG its interior spans a hole which corresponds essentially to the cross-sectional area of the interior space formed in the interior of the hollow housing body.

In lighting devices according to the invention, at least two translucent housing segments that are transparent or translucent are combined. This is necessary in order to enable radiation that is as uniform as possible over the largest possible area of the room. Here, the design with translucent housing segments has proven to be particularly advantageous, since the impression of corresponding lighting devices according to the invention is regularly perceived as particularly appealing during operation. In addition, the inherently large amount of light scattering in these materials means that additional scattering, which is generated by material boundaries in the area of the connection areas or the connection frame, is not as important optically as with transparent materials. A lighting device according to the invention is preferred, the first housing segment and / or the second housing segment, preferably all housing segments, being translucent. A lighting device according to the invention is particularly preferred, the first housing segment and / or the second housing segment, preferably all housing segments, having a transmission of more than 10%, preferably more than 20%, particularly preferably more than 50%, for electromagnetic radiation in the range of visible light. , very particularly preferably more than 90%, and / or have a transmission of less than 80%, preferably less than 50%, particularly preferably less than 30%.

The inventors of the present invention have succeeded in identifying materials with which the housing segments of the lighting device according to the invention can be produced particularly efficiently and with which lighting devices can be obtained which have excellent weather resistance. A lighting device according to the invention is namely preferred, wherein the first housing segment and / or the second housing segment, preferably all housing segments, are formed from materials selected from the group consisting of plastics, preferably selected from the group consisting of polyesters and poly (meth ) acrylates.

As explained above, in lighting devices according to the invention it is advantageously not necessary for the housing segments to be connected to one another via further connecting elements. For certain applications, however, it may be preferred to achieve an additional degree of robustness by connecting the housing segments to one another by means of further measures. In contrast to gluing, which has not been identified as advantageous here, mechanical connections using mutually complementary connecting elements have proven to be advantageous, as they occur in particular with screw threads or bayonet locks, the latter being explicitly preferred because they are used in housing segments Usually occurring material thicknesses are regularly easier and more cost-effective to manufacture and still ensure an effective additional connection. A lighting device according to the invention is therefore preferred, wherein the first housing segment and the second housing segment in the connection area have mutually complementary connection elements for the reversible and non-destructive detachable connection of the housing segments.

With regard to the connection frame, a variety of materials can be used, with a view to the long-term stability of the connection that can be produced and the weather resistance, in particular metals and plastics being suitable, the inventors suggesting that materials similar to those used for the housing segments can advantageously be used. In this respect, a lighting device according to the invention is preferred, the connecting frame comprising a material selected from the group consisting of metals and plastics, preferably selected from the group consisting of polyesters and poly (meth) acrylates.

In principle, a lighting device according to the invention is preferred, the connecting frame being designed as an essentially rigid frame. However, a lighting device according to the invention is particularly preferred, the connecting frame being designed to be elastic.

With a view to the optical effect and the most harmonious lighting performance possible in all spatial directions, it has proven to be particularly advantageous if the connecting frame is designed to be essentially opaque so that the connecting frame, in addition to its connecting function, can also serve to conceal uneven lighting properties in the connecting area. A lighting device according to the invention is consequently preferred, the connection frame being essentially opaque, the connection frame preferably having a transmission of less than 1%, preferably less than 0.1%, for electromagnetic radiation in the range of visible light for all wavelengths.

In principle, it is possible to design the connecting frame so that it protrudes on the outside of the lighting device, which can make it easier, for example, to make the sometimes very large and unwieldy lighting devices easier to transport in the assembled state by the frame acting as a grip option. For most applications, however, it is preferred if the connecting frame in the assembled state can be assembled with the housing segments as seamlessly as possible to form a housing body which has an outer surface that is as smooth as possible. This is preferred not only for visual reasons, but also has a clear technical effect. Due to the smooth surface and the lack of protrusions on which dirt and moisture can accumulate, the weather resistance and durability of the lighting device are increased and the maintenance effort is reduced. A lighting device according to the invention is accordingly preferred, the outer contour of the connection frame corresponding to the outer contour of the first housing segment and of the second housing segment in the connection area of the respective housing segment. A lighting device according to the invention is also preferred, the connecting frame being designed in such a way that the connecting frame and the housing segments can be connected to form a hollow housing body with a smooth outer surface.

Embodiments are particularly preferred in which the connecting frame is designed as a circumferential frame element, for example as a ring, similar to a clamp, the walls of which have a certain height, but which only has a comparatively thin wall thickness in plan view. In such a frame element, the first housing segment and the second housing segment, the connection areas of which are appropriately pre-structured and thus matched to the connection frame, are inserted in such a way that the first and second housing segments abut and directly touch each other when connected. This embodiment is preferred because it is particularly easy to implement. However, with a view to weather resistance and durability of the connection, it is preferred if the connection frame additionally has a material web that extends from the edge in the direction of the center point and is arranged between the first and second segments in the connected state of the housing body, so that these are not in direct contact with one another. Accordingly, a lighting device according to the invention is preferred, the connecting frame having a circumferential delimiting element which is designed such that the first housing segment and / or the second housing segment can be inserted into the connecting frame in such a way that they are held under tension in the circumferential delimiting element in order to achieve a to generate at least partially non-positive connection, the circumferential delimiting element preferably having projections or depressions which are designed to interact with projections or depressions in the connection area of the housing segments.

In the light of the above explanations, many different configurations are conceivable for the connecting frame. In addition to the embodiment of a cuff arranged in the connection area, in which the housing segments are in abutment, and a frame which also has a web that separates the housing segments when connected, it is also conceivable that the connection frame is completely formed by a wider material web , which is arranged between the housing segments when connecting. A lighting device according to the invention is therefore preferred, the connecting frame comprising a material web, the width of the material web of the connecting frame being 50 to 150%, preferably 75 to 125%, particularly preferably 85 to 115%, very particularly preferably essentially 100% of the material thickness of the first Housing segment and / or the second housing segment in the connection area of the respective housing segment.

In all configurations of the connection frame, however, it is preferred to provide structural elements on the connection frame for better connection of the housing segments, for example projections or depressions that can interact with complementary macroscopic structures in the connection area of the housing elements in order to enable better interlocking. A lighting device according to the invention is therefore preferred, the connecting frame having macroscopic structural elements which are designed to interact when connecting to a macroscopic structure in the connecting area of the first housing segment and / or the second housing segment in order to produce an at least partially form-fitting connection.

Even if this is usually associated with higher costs and greater manufacturing effort, it can be useful for certain applications to additionally provide one or more sealing elements, for example sealing rings, in the connection frame in order to create a particularly moisture-proof connection. Corresponding lighting devices are also suitable for use in, for example, if designed appropriately Suitable for waters or in the bank area. A lighting device according to the invention is therefore preferred, the connecting frame comprising one or more sealing elements, preferably one or more sealing rings.

Although the lighting device according to the invention also unfolds its advantages in the non-assembled state, in particular with regard to improved storability, a lighting device according to the invention is explicitly preferred which is in the assembled state and in which a light source is preferably already arranged in its interior. A lighting device according to the invention is preferred, wherein the connecting frame is connected to the first housing segment and the second housing segment in a reversible and non-destructive releasable manner via a form fit and / or force fit, the base element being arranged in the receptacle so that the socket is located in the closed interior space, and where one or more illuminants are preferably arranged in the socket.

The lighting device shown 10 comprises a base element 12th with a socket 14th for holding illuminants 16 , each in 2 can be recognized.

In addition, the lighting device comprises 10 a hollow case body 18th with a receiving opening 20th in the outer wall 22nd , which is particularly important in the 2 and 3 is easy to see. The receiving opening 20th is set up for this purpose, the base element 12th include so that the base element 12th the receiving opening 20th closes and inside the hollow housing body 18th a closed interior is formed, as in 1 is shown.

The hollow case body 18th comprises a first housing segment 24 , a second housing segment 26th and a connection frame 28 where the connecting frame 28 for a better understanding in 1 is hidden in order to make the structure of the connection area more visible. The first housing segment 24 and the second housing segment 26th are each designed as hollow half-shells, the first housing segments through the in the outer wall 22nd arranged receiving opening 20th is flattened and at the receiving opening 20th has a protrusion to which a screw thread is attached.

In the illustrated lighting device 10 are the first housing segment 24 and the second housing segment 26th completely translucent and, just like the opaque connecting frame 28 , made entirely of plastic. As in 2 shown is that of the connecting frame 28 reversible and non-destructively releasable via a form fit with the first housing segment 24 and the second housing segment 26th connected.

The lighting device 10 includes on the base element 12th Means of anchoring 30th of the base element 12th in the ground, namely in the form of a tapered wedge.

Also include the base element 12th and the first housing segment 26th complementary means for connecting the base element 12th with the hollow case body 18th , which are designed as screw threads.
