Description

I. Field of application

The The invention relates to a path lighting, in particular a roadside lighting.

II. Technical background

at outdoor facilities have to Paths only for security reasons be well lit at night. In addition, the lighting also fulfills others Purposes such as positively highlighting the building environment, if necessary Advertising effect etc.

These Illuminations become frequent realized by standing lights, lanterns or the like, where a big creative selection exists.

adversely However, this is a difficult, even outdated selection in terms of design, the installation effort is relatively high, since in 220 V technology must be worked, and appropriate sealing measures must be taken against moisture and also the energy needs given the 220 V technology used and the matching bulbs is not insignificant.

Additionally acts it is with these outdoor lighting regularly for more or less punctate Illuminants that irradiate a certain area, and accordingly be used with sufficient distance and frequency have to, if the desired continuous lighting is to be achieved.

The this way to be illuminated are often provided with a surface, which is achieved by paving stones through paving stones, or by coatings from tar, concrete or similar Materials on a suitably prepared surface.

One Another problem of individual lamps is the risk of damage, be it unintentionally by z. As cars, be it intentionally Vandalism, dar.

The margins The paths are already for static reasons usually with one Limitation of curbs provided in the form of vertical Concrete blocks or concrete slabs left and right of the way together subsequently embedded in the soil as far as possible and thereby stabilized, and as far as from the ground to a separation between the pavement of the sidewalk on one side and the adjacent one Outdoor facilities, z. B. planted soil on the other side to form.

These Curbs need anyway in the plant of ways are always set to the at Compacting the substrate and applying the topcoat occurring personnel to catch to the side, and have to exactly for that reason and for the long-term dimensionally stable recording sufficiently deep buried become so later also the frost effect causes no displacement of these curbs.

Furthermore, it is from the DE 694 16 964 T2 known to equip concrete curbs with a lamp body, which is poured into the concrete part with.

Out For this reason, the lamp body is elaborately made there with the help a circumferential trough into which another metal profile is inserted which is a plurality of openings for the passage of LEDs, wherein subsequently the space above the profile inside the tub filled with a mixture of glass beads and a binder and hardened becomes.

In order to is the electrical part of the lamp body, so the LEDs with associated wiring and if necessary, electronics, through the tight tub and the opposite of the Tray sealed cover moisture-proof enclosed, leaving it on a moisture-proof attachment of this tub in concrete no longer arrives.

These However, the procedure is very complex and can not be done if necessary To be repaired by replacing the lamp body and, above all, requires providing the finished lamp body before casting the Concrete parts and accordingly careful approach when casting the Concrete.

III. Presentation of the invention

a) Technical task

It is therefore the object according to the invention, a beacon available which is simple and inexpensive to manufacture and assemble and in particular sharing the anyway necessary boundary stones.

b) solution the task

These Task is by the claims 1 and solved. Advantageous embodiments emerge from the dependent claims.

A particularly simple and cost-effective solution is obtained if a conventional concrete body, ie a molded block, is used as the base body poured concrete, is used, the outer dimensions correspond in particular to those of a conventional concrete curb yes have an upright, rectangular cross-section and usually set in Einmeterlänge successively set and thereby be embedded over at least half in the underground.

In such a socket body made of concrete would have only to the desired Provide one or more wells for insertion of the lamp body provided be, for example, on one of the tops or one of the side surfaces or both, and he would have to depending on the arrangement of the lamp body the light emission up or to the side on the walk-in area get executed.

to electrical connection of the lamp body goes from this recess from a respective passage opening through the concrete body on z. B. the opposite lying side surface or to one of the faces.

Of the concrete body will be in its stability hardly weakened, if the depression is not particularly deep, for example not is more than 2 inches deep.

so flat luminaire body can despite having a thick and stable glass cover, by covering as a glass plate of about 10 to 16 mm thickness is used, preferably with sandblasted roughened outer surface and as a back wall of the lamp body, the has a dimension analogous to the cover, directly the board is used on the as LED bulbs, and in particular in the form of only about 1 mm high flat LED's, be used.

If now the lamp body is glued into the recess by placing between the side surfaces of the Cover and the circumferential flanks of the recess in the socket body Glue is introduced, no moisture can on the itself as well moisture-proof cover over or through it penetrate, making the lamp body waterproof to the Environment is sealed.

A particularly simple solution is thereby achievable that a concrete molded body with upright rectangular cross-section the desired Depressions both in one of its narrow sides, ie the upper side, as well as in one of the side surfaces in the upper area, facing away from the indented Narrow side, has and extending from there through the concrete body through holes approximately in the same area of the other side surface.

One such shaped body can then either be set so that he with the recess used in the narrow top facing up, so that the other depression in the side surface disappears afterwards in the underground, or rotated 180 ° vice versa, so that the shaped body with the narrow side of the depression gets up below on the ground and using the recess in the side surfaces to later arrange a lamp body becomes.

Important is that the shaped body so far as are embedded in the underground, that the mouths their passages still below the ground level, but still above the Stabilizing wedges made of lean concrete, in the lower side Area on the base bodies is arranged.

When another possibility can the molded body the Recesses in the top and the side surface in the same half, so in set moldings both above ground level, have.

By the formation of the cover of the Wegleuchte one hand with a high proportion of glass, but not only of glass, but at the same time so stable that the cover is walkable or even passable is causes the beacon either as part of the walkable surface of a z. B. way or a driving surface used is, or as part of, in particular essay auf, the anyway necessary curb as a boundary between a walk-in / passable area and the environment acts.

By the high proportion of glass, the cover is largely made a natural material, like this for outdoor facilities often and when using glass particles, in particular in the form of glass moldings, be it by accident or always about the same shape, additionally results in a Shape of the cover whose surface is natural Material very similar to gravel works, especially if the glass moldings in whole or in part have a shape or size, that of similar to pebbles is.

This is for example the available semi-finished glass product in the form of non-sharp glass drops, glass cushions or the like the case, as a granular semi-finished product for further processing and remelting commercially.

The glass particles, for example, a sharp-edged glass granules, are bound by a suitable binder, usually curing plastic, to the extent that it is possibly waterproof and above all sufficient in the transverse direction to his Main level is resilient to be walkable or passable at a given maximum areal dimension, which is usually the case for larger areas with a thickness of 1 to 4 cm.

The Integration in the binder, in particular plastic, takes place in the upper layer of the glass particles only so far that these still sufficiently protrude from the binder to the effect to produce a partially bound particle coating. While the Glass particles preferably consist of clear glass, anyway largely translucent are, this is for the binder is not a mandatory condition, but an advantage.

The Cover is in a generally completely encircling mounting frame inserted and limited in their mobility in the transverse direction. The Cover can be either with its bottom on parts of the Aufnahmerahmens rest, or on the component on which the mounting frame itself rests, for example, a curb made of concrete. The recording frame is usually made of a non-rusting material, such as stainless steel in the form of sheets or profiles. The used as bulbs LED's below the cover are arranged waterproof opposite penetrating surface water as well as rainwater can be arranged.

This is achieved by the luminaire body in which the LEDs are waterproof across from the environment is sealed, and in this case, the cover waterproof opposite the receiving frame must be sealed.

A different possibility consists in that the individual lamps, in particular LED's, individually or together are enveloped waterproof as a lighting unit, for example by Inclusion in transparent plastic, especially in a plastic tube or a potting compound, and then inside the lamp body, z. B. attached to the underside of the cover or the support frame are.

Also a single plugging the wired LEDs into corresponding Blind holes in the bottom of the cover is possible, in particular by sealing with rubber grommets.

As well can several LEDs, however also arranged together on top of a board or otherwise be connected to each other, which is positioned inside the lamp body and attached.

there be inside a lamp body several LEDs, mostly in several shades, arranged, which are individually dimmable and controllable, creating the desired mixed color can be set exactly.

at grid-like arrangement of the LEDs can by means of a corresponding dot matrix also fonts or symbols be represented by control, both at rest as also as along the plane Wegleuchte wandering representation, even over several juxtaposed Way lights away.

To For this purpose, the bulbs are the individual units LED's carry, and of which there is at least one within each individual body, interconnected both electrically and control technology and communicate with a control unit that covers the entire Path lighting controls.

Depending on the current situation, completely different types of lighting can be specified by means of the controller:
In addition to the periodic inclusion of advertising messages, company logos, etc. between the simple emergency lighting for the sidewalk Leitanzeigen be aufschaltbar, for example, in a parking garage to the area where parking is still free.

As well can by means of a wireless control device, such as a transponder, that a particular customer or operator carries with him Lighting in dependence switched from the current position of this customer or transponder be illuminated, either by only the appropriate area or by tailoring to this customer / transponder management task Fulfills becomes, so the concrete introduction by means of symbols illuminating in the directional lamp in the surroundings the user to a specific destination desired by him.

There the route guidance symbols only in the environment of the respective user can light up this way even a larger number of users in a larger facility, be it a company premises or a mass, to their respective destination.

Likewise, the lighting can be varied in this way, for. B. automatically due to twilight switches, time or similar factors. For this purpose, offers a coupling of such a control unit with an external computer, for example via the Internet, preferably wirelessly to change depending on different current tasks, the control of the light source in the short term can.

Of the Lamp body, especially including the holding frame, can directly into the walk-in, z. B paved, area be integrated while doing so like a paving element on the accordingly prepared and compressed underground or a compensatory Split layer are laid. Depending on whether the lighting units or bulbs are an integral part of the lamp body or only loosely associated with the respective cover, must Illuminant units are either laid previously on this substrate, or are laid together with the lamp bodies, of course, under electrically conductive connection of the lamp units of the individual lamp body with each other. If the illuminant units are separate assemblies, they can have a Row of lamp bodies formed throughout without contacting connectors be, for example, as a harness, housed in a plastic tube etc. about which then the covers, optionally together with the support frame, be laid in pavement technology.

specially can do this the cover one, z. B. in the longitudinal direction extending, downwardly open recess to the full height or partial reception of a linear lamp unit. The cover then lies with its undersides next to the recess on the ground, using by sealing lips or similar formations on the lamp unit or the plastic hose enclosing this prevents that within the recess between lighting units and cover material of the pavement underground, so sand or Gravel, passes.

There when housing the lamp body in the walk-in area and in alignment with this the light emission is always upwards, takes place mainly an orientation by the light of the lamp body for the user instead, not However, a direct illumination of the walkway path away of the lamp body. For this purpose, the lamp body is used mounted on a base body, which corresponds in its function and / or shape to the curbs, as opposed to the demarcation of a tarred or paved road surface Environment can be used. Just like this curb is the Base body over the large part his height embedded in the ground, also by frost effect in winter to maintain its position exactly, especially against the subsequent Curbstones.

To above is the socket body usually a few up to about 30 inches above, so that its top as a support surface used for the lamp body can be. The luminaire body then sits either with its mounting frame on the top of the socket body on, or directly with the bottom of the cover, being in the latter Fall through recesses in the bottom of the cover and / or in the top of the socket body room for the accommodation of the lighting units must be created.

With This design makes the construction especially resistant to vandalism and theft of the lamp body accomplished be. For this purpose, the lamp body is fixed, but detachable, with the socket body connected, for example by screwing by special screws or one preferably form-fitting acting latch, which are solved by introducing a specifically shaped key body can. Also, the cover itself must be opposite the mounting frame or other housing of the lamp body sufficient be securely fixed, allowing a lock preferably simultaneously the housing or the receiving frame from the socket body solves and in particular the Cover from the mounting frame.

Of the socket body itself is like a conventional one Curb made of poured concrete or as hollow metal construction from z. B. stainless steel sheet.

Important are in both cases sufficient, preferably vertically from top to bottom, cavities for the feed the energy supply from below and / or as drainage channels for rainwater from top to bottom, especially to backwater inside the lamp body reliably too avoid.

at execution of the body as a hollow body can this additional be used for the accommodation of rechargeable batteries by the outside the socket body applied solar cells during the day be fed to thereby independent of the connection to a to become electrical power network. Also the control unit for one or several luminaire body can in a hollow base body theft-proof housed.

In another embodiment, the receiving frame on at least one side have openings behind which are also parts of the cover, so that through the lateral parts of the cover and the lateral openings through a light leakage to the side and thus also obliquely down on the walk-in / drivable path area takes place. For this purpose, the cover not simply plate-shaped, but preferably angularly or at least in terms of the outer contour in cross-section triangular out forms his.

One Another advantage of an angular or convex shaped cover achieve by not placing one of the flat sides of the cover horizontally in terms of of the socket body is positioned, but so that the surfaces of the cover respectively aslant stand, so roof-shaped or convex upwards or even at an angle standing crowning, especially in winter slipping off To facilitate snow and thus the functionality of path lighting to increase.

Though also takes place by the heat release of LED's a warming of Cover, however, this is so low that an additional Support by inclination the surface is to be preferred.

specially It may be advantageous to the lamp body or at least its Cover in different angular positions on the upper area of the socket body to be able to fix to thereby influence the direction of the light output.

Offer for this For example, there are two at different levels Support surfaces on the top of the socket body to the specifically shaped body of the cover thereon in for example two rotated by 90 ° To be able to place positions and thus change its angular position of the tops.

Preferably However, at least part of the frame should be, for example in the form of vertical thighs, above the level of the bottom extend down the cover, and laterally outward beside the outer surfaces of the socket body after extend down to a particularly stable and especially theft-proof connection between base body and luminaire body to enable.

On this way you can critical paths such as roadsides, Stages on the way etc. either continuously or with a gap in between with lamp bodies be equipped, thereby reducing the dangerous places on the one hand is pointed out and these are mitigated by lighting at the same time.

c) embodiments

Embodiments according to the invention are described below in FIG 5 described in greater detail for example. In the 1 - 4 the invention is not - or at least not completely - realized. Show it:

1 : a partially cut representation of two applications,

2 in cross-section two alternative solutions,

3 : different installation solutions of the same cover,

4 : a total solution,

5 : another solution.

1 shows in the left part of the picture the lamp body 1 placed on a mostly underground 30 recessed socket body 20 and with this firmly connected, in the right part of the picture, however, with the top of the lamp body 1 namely its cover 3 , ground level to the ground 30 for example, when used as a paving stone.

The elongated, strip-shaped lamp body in both cases 1 is in the left part of the picture on a base body 20 in the form of a raised, up to 2/3 buried in the ground, randsteinartigen base body 20 placed on its top. The luminaire body 1 In this case, it includes a receiving frame, which is closed in particular when viewed from above 5 for example, from angle profiles 5a made of stainless steel, as shown on the left edge, or a simple vertical sheet metal strip 23 as on the right edge of the socket body 20 shown. In this case, this vertical leg extends 23 or an analogous vertical leg of a used profile 5a along the outsides of the socket body 20 down, especially around a fixed screw, preferably just below the surface of the substrate 30 , or otherwise possible positive locking with the socket body 20 to allow for a theft of the lamp body 1 reliably prevent.

For this purpose, for example, a locking device 24 used, as it is used in a similar manner for locking bollards, barrier grids, etc., and in which a specific, in particular provided with a triangular inner contour, key element 24a must be placed on a corresponding triangular pin and rotated to the locking device 24 to solve.

The luminaire body 1 further comprises a plate-shaped cover 3 with a high proportion of glass, which will be explained later, which is inside the frame 5 is used and preferably also not firmly glued there but is releasably held.

Below the cover 3 are the individual light sources 2 in the form of LEDs 6 or summarized to illuminant units 2 ' by B. several LEDs 6 on a circuit board 8th are housed.

In this case, the lighting unit is located 2 ' in a depression 22 the top of the socket body 20 , preferably in the longitudinal direction 10 over the complete or nearly complete length of the base body 20 extends and from one or more drain holes 17 through the socket body 20 pass through for the discharge of rainwater etc.

While in 1 the cover 3 is arranged so that its top 3b is horizontal, is in the solution according to 2 first made sure that in the assembled state the top 3 slightly inclined, at an angle 18 preferably to the path to be illuminated 25 inclined, runs to facilitate the slipping of snow or drainage of water.

In addition, according to the solution 2 the socket body 20 ' not equipped with a flat top, but with a longitudinal direction 10 viewed, stepped surface, which is located on the left and right edge two located at different height levels support surfaces 21a , b show the placement of the lamp body 1 , Again, the cover 3 circulating from a mounting frame 5 surrounded, however, are in the vertical thighs of the cover 3 at a height above the base body one or more openings 31 present on one side, also from the translucent cover 3 are deposited.

The cover 3 is designed angularly for this purpose, wherein acting as a light emitting diode 6 are arranged in the inner angle, either with the base body 20 ' connected or with the cover 3 or their recording frame 5 ,

The here as upwardly substantially open hollow structure, for example made of stainless steel sheet, illustrated socket body 20 ' Can be used to hold batteries 32 Serve and / or the electrical control unit 7 ,

It can cover 3 either as in 1 , left edge of the socket body 20 shown, rest indirectly on the base body with the interposition of a leg of the receiving frame 5 on the support surface 21a of the socket body 20 , or as on the right edge of the socket body 20 shown directly on the support surface 21b , In the same way are also in 2 both possibilities at the left and right edge of the socket body 20 shown.

Furthermore, the figures show a solution, one and the same cover 3 '' , which is also formed again approximately angularly viewed in the longitudinal direction, in two different rotational positions, on the base body 20 ''' placed in order to thereby different angular positions of the tops 3b ' . 3b '' to achieve:
Again, the socket body 20 ''' for this purpose two lying at different height levels support surfaces 21a . 21b but in this case are not flat, but spherical concave, while the corresponding free ends of the angular cover 3 '' are formed similarly convex convex.

The vertical distance of the support surface 21a , b is sized so that when placing the cover 3 '' in one position, as in 3a shown, which is an outside 3b '' lying horizontally and the other outer surface 3b ' vertically, preferably in alignment with one of the outer surfaces of the socket body 20 ' ,

With rotated support of the cover 3 '' according to 3b in the same support surfaces 21a , b are the outer surfaces 3b ' . 3b '' each obliquely and generally roof-shaped on the base body 20 '' on, which facilitates the slipping of snow, while in the illustrated solution acc. 3a through the vertical outer surface 3b ' the cover 3 '' light is also emitted obliquely downwards, provided the bulbs 2 inside the lamp body 1 is positioned accordingly.

In the example of 3 is the cover 3 '' not just to the side of the frame 5 '' held, but secured by its inwardly bent upper edges against lifting up.

Also the attachment of the bulbs 2 is different:
While in 3b the lighting unit 2 ' , consisting of a circuit board 8th with LED's arranged on it 6 , on the top 20a of the socket body 20 under the roof-shaped positioned cover 3 '' lies and not with the cover 3 '' must be connected is in 3a every single LED 6 as inserted into a blind hole opening 15 from the bottom of the cover 3 '' shown sealed from the inner periphery of the blind hole 15 by means of a rubber grommet 16 , at the same time for the stable attachment in the blind hole 15 provides.

In this way, a plurality of LEDs can along a quasi-infinite cable harness 6 attached and individually in corresponding blind holes 15 be fixed, even over several luminaire bodies 1 time.

3a also shows in an enlarged view the internal structure of the cover 3 '' :
Here are a variety of glass moldings 13 , which are designed in this case about pillow-shaped, tightly packed and made of a plastic 4 enclosed as a binder and adhesive connected to a plate-shaped structure, wherein the shaped body 13 on the top 3b the cover 3 from the glue or binder, usually a plastic 4 , projecting to provide the visual impression of a gravel road or similar.

In addition, the show 1 and 2 in the right half of the picture the use of the lamp body 1 as a paving stone, so with the surface 3b of the lamp body 1 aligned at ground level with the accessible or passable path area 25 :
It shows 1 in the right part of the picture a solution in which the plate-shaped cover 3 in a recording frame 5 from circumferential angle profiles 5a is inserted, the vertical, free ends above free leg ends with the upper edge of the cover, and on the horizontally extending other leg of the edge region of the cover 3 rests.

With the remaining surface of the bottom is the cover 3 on the ground, usually a layer of split or sand, on, up to the middle area, in which in a depression of the substrate, the lighting unit 2 ' arranged from one of a transparent plastic tube 9 tightly closed sequence of LEDs 6 , for example, applied on one or more boards 8th , consists.

Of course, also the front ends of the plastic tube 9 tightly sealed, so that the entire electrical unit is waterproof, and thus the penetration of moisture z. B. between the cover 3 and the recording frame 5 including the downward seepage is insignificant.

In contrast, shows 2 in the right half the use of the plate-shaped covers 3 alone as paving stones, but the likewise line-shaped lighting units, which are not shown here for reasons of clarity, inside a in the bottom of the covers 3 trained recess 27 Find space so that in the underground in the preparation no, wells must be provided.

The illuminant units are for each cover 3 and with it every lamp body 1 separately formed and in particular each with the corresponding cover 3 firmly connected.

The illuminant units are before or when laying over electrically conductive fasteners 14 coupled together. A recording frame is not needed in this case.

4 shows a total solution with a staircase at the bottom in a pathway 25 passes.

It can be seen that along each step on the tread surface near the front edge of a lamp body 1 with the cover 3 is arranged as part of the tread surface, partially with a side surface 3a in the upper area of the face of the stairs.

In addition, the edges of the adjoining the stairs way surface 25 at the outermost edge in each case with in the longitudinal direction of the roadway 25 extending strip-shaped lamp bodies 1 and their covers 3 at ground level, so used as a paving stone 26 , fitted.

By such facilities are both walkways and the stairs outside adequately lit and secured.

A solution that deviates very little from the processing by a horticultural firm or plaster company from the previous procedure, show the 5 :
As boundary stones on the edge of a paved area are perpendicular base body 20 made of concrete, usually with rectangular, upright cross-section used, which are usually arranged in one-meter pieces in a row like a wall.

To be stable against sideways approaching cars, these socket body 20 in the form of curbs more than half buried in the ground, sit with their lower narrow side on a band-shaped base made of in-situ concrete or lean concrete, and in addition, after being placed in the lower part of the curb stone from both sides of a stabilizing wedge 38 accumulated from concrete, and then about soil filled to the desired height or applied to the soil of the desired floor covering.

When finished, the curb does not even halfway over the top of the floor 30 out.

The 5 show the processing of such concrete body, with respect to the path lights as a socket body 20 are distinguished, and differ from the above-described solid concrete blocks with rectangular cross-section in that both in the one narrow top 20a as well as in one side surface 20b1 at least one extending in the longitudinal direction, z. B. strip-shaped recess 22 , preferably continuously up to the end faces of the socket body 20 or also a plurality of individual depressions arranged in the longitudinal direction 22 are arranged.

The depression 22 in the side area 20b1 is located in the height range in the from the top recess 22 turned away half. From each well, a through hole runs as a drain 17 through the socket body 20 through and opens on one of the other outer surfaces of the base body, in this case on that side surface in which no recess 22 located.

In the wells, a z. B. rectangular contour and can be about 2 to 2.5 cm deep, are lamp body 1 let in, their surface opposite the surrounding surface of the base body 20 is lowered slightly.

As 5a shows, such a socket body can be set in two different ways:
Either - as shown in the right half of the picture - so that the top 20a above and thus from the ground above, in which the depression 22 is arranged. In this depression then the lamp body 1 inserted and connected so that it emits light mainly upwards.

Will the socket body 20 - As shown in the left half of the picture - processed rotated by 180 ° about its longitudinal axis, so then sitting in the narrow side arranged recess 22 in the underground.

This is then the in the side surface 20b1 arranged recess 22 in the upper half of the side surface and thus above ground level, so that there is a lamp body 1 can be used and connected, which then emits its light mainly to the side and also obliquely down on the walk-in area.

Thus, one and the same concrete block as a base body 20 serve for two different applications. The luminaire body 1 is z. B. as in 5b shown - constructed and can thus very flat, with a height less than 2 cm, are held:
A sufficiently thick and stable glass plate, for optical reasons with roughened, z. B. sandblasted surface 3b , forms the cover 3 of the lamp body 1 ,

As a back wall 33 of the lamp body 1 is preferably used directly the board 8th on which are the LEDs 6 , namely LED's in the special form of flat LED's, which can be applied automatically with SMD technology, are located, in particular in a fixed, always uniform grid.

This board 8th can either by means of a circumferential spacer frame 34 from a hollow profile, between the back of the cover 3 and the front surface of the board 8th is peripherally glued, spaced or by means of a much thinner spacer plate 39 whose thickness is only slightly larger than the height of the flat LED's 6 So about 1 mm.

This spacer plate 39 lies flat on the entire back of the cover 3 on the one hand and on the entire front of the board 8th and is preferably glued surface in this area, and has only in the areas where the LED's 6 are arranged, corresponding breakthroughs.

This design is particularly flat and pressure stable, however, the light control and the luminous effect are slightly better when the distance between the LEDs 6 and the cover 3 something bigger.

The glued body so without further aids, especially without additional mounting frame or the like directly into the only slightly larger in size from the greater depth 22 set and preferably by means of silicone adhesive, etc. between the side surfaces 3a the cover 3 and the flanks of the depression 22 on the one hand sealed and on the other hand fixed.

The from the back of the lamp body 1 Leading electrical leads are through the water drainage opening 17 passed, at the opposite opening they run with a running in the longitudinal direction of the curb series electric cable, preferably there in a conduit, but in any case buried in the underground, laid.

Of the Effort for Waterproofing can be kept low, as - as with the rest All above-described types and solutions - the electrics preferably executed in 24 V technology and thus attacking moisture raises no major problems.

In addition, a theft protection on the lamp bodies 1 be provided by a clamping element 35 from the opposite mouth of the corresponding water outlet opening 17 out and with the rear end of the lamp body 1 is connected and this in the recess 22 holds. This can be, for example example, be a stainless steel threaded rod of 3 to 5 mm in diameter, on the back of the lamp body 1 is hung on and from the opposite side of the base body 20 a clamping nut is screwed on.
