Technical field:

The invention relates to a lighting device with a lamp and a lamp housing which receives the lamp for a lamp post supporting the lamp housing, according to the preamble of claim 1.

State of the art:

It is known to design lighting devices, in particular those for public areas such as street, footpath and park lighting, as a lamp arranged on the top of a lamp pole. As a result, a large area around such a lighting device can be illuminated and the illuminant is protected against damage and contamination. A generic lighting device is known for example from the German design M 8907946.9. All-round radiation of the light has the advantage of simple manufacture, since it is sufficient to arrange a lamp on the top of the lamp mast, but it also has the disadvantage of untargeted illumination of areas that do not need to be illuminated or should not be illuminated. In addition, such known lighting devices are not suitable for illuminating buildings or objects in public space, since the light radiation emitted is usually not sufficient due to the large scattering angle to obtain satisfactory illumination, for example of a facade.

For illuminating facades of buildings, it is known to use high-performance spotlights which are embedded in the floor or are arranged on opposite buildings or on masts. However, these known lighting devices have the disadvantage that people who are located between the high-performance spotlight and the facade to be illuminated are severely blinded and, in addition, the facades of neighboring buildings are often disfigured by the high-performance spotlights arranged thereon because they do not move into the facade insert. The lack Aesthetics only allow a limited and usually not permanent use in urban areas or in public spaces when installing such spotlights on the top of a lamp mast, especially since additional lighting devices are required for normal street and path lighting. The known lighting devices, in particular for public roads and streets, additionally have the disadvantage that necessary repairs to the lights, the lamps or the associated electronics always have to be carried out on site, which results in high maintenance costs.

DE 298 07 056 U1 is a light polisher for limiting and / or nocturnal lighting of walkable and / or passable traffic areas, consisting of an at least partially hollow, columnar, upright bollard body, in which at least one, preferably electrical, light source is arranged, the one of which Light passes through at least one window-like light opening to the outside. A first light source and a second light source are arranged in the bollard body, which is hollow at least approximately over its entire height, the first light source emitting its light essentially upwards through an end light opening and the second light source emitting its light outwards through a second light opening, which extends like a band at least in the lower area of the bollard body from bottom to top.

Furthermore, DE 200 07 434 U1 has disclosed a light bollard with an electrical light source which is arranged in a closed, columnar bollard housing which has at least one light window through which the light from the light source emerges essentially horizontally. The light source is arranged in the center of a flat light guide body made of translucent material, the light exit surface of which is arranged in the circumferential area of the bollard housing and the essentially parallel plane surfaces are at least approximately completely mirrored. The light guide body occupies an essentially horizontal position in the vertical bollard housing.

Technical object of the invention: The invention is therefore based on the object of developing a maintenance-friendly lighting device which allows multiple objects and areas to be illuminated in a targeted manner and which, moreover, can be integrated inconspicuously in public and private areas.

An additional purpose of the invention is to create a lighting device which is also aesthetically satisfactory due to the technical design and which is accepted by the population as an enrichment of the public space.

Disclosure of the invention and its advantages:

The solution to the problem is that, according to the invention, the lamp housing is designed as a module which can be placed and removed on the lamp mast, which module has at least one interior receiving at least one lamp and, over part of its outer circumference, a sector-shaped cut-out light opening, the module at its lower one End on the underside facing the lamp post and at its upper end on the top side facing away from the lamp post each has a lead-through opening, each with a fastening device for a further module of the same design, for arranging several modules one above the other, the lead-through openings being aligned one above the other and the fastening devices on the top and are designed to correspond to each other on the underside.

The device according to the invention with the characterizing features of the main claim has the advantage over the prior art that the lamp housing is designed as a module that can be fitted and removed on the lamp mast. This module has at least one interior protected from the weather, at least one illuminant and possibly an electronic ballast required for the illuminant and a lamp reflector, and at least one sector-shaped light outlet opening that extends over part of its outer circumference for targeted radiation of the one arranged in the interior Illuminant emitted light. The radiation angle of the light in the circumferential direction corresponds at most to the sector angle of the light exit opening. On the underside of the lower end of the module facing the lamp mast and on the top of the upper end of the module facing away from the lamp mast, the module in each case has a lead-through opening for the supply lines for the lamps and / or other technical devices arranged in the interior, and a fastening device for each another module, the through openings being aligned one above the other and the connections on the top and on the bottom being designed to correspond to one another, so that the fastening device on the underside of the module fits onto the fastening device on the top of the module and at least two modules one above the other the lamp post can be arranged. A standardized assembly is created by the module housing, the interior, as well as at least one light drop opening on the outer circumference of the module housing and the fastening devices on the top and bottom as well as the through openings, whereby the modules of the assembly are interchangeable with each other, so that the assembly or set has standardized fastening devices and through openings. Any modules that can have different functions can thus be connected to one another at the fastening devices provided for this purpose.

The radiation of the light emitted by the illuminant within a limited sector has the advantage that the light can be used in a targeted manner and that differences in brightness, for example in facade lighting, can be better compensated from a short distance by the simpler shape of the reflector. In this way, disturbing or undesired scattered light, for example in the case of lighting devices arranged next to private property or ponds, can also be specifically prevented and the light yield at the points or surfaces to be illuminated can be improved. The radiation is not only limited to horizontal sectors, but can also be restricted to vertical sectors, so that glare from, for example, facade lighting people staying between the lighting device and the facade can be avoided by targeted lighting above a minimum height.

An advantageous embodiment of the invention provides that modules arranged one above the other can be arranged pivoted relative to one another in the horizontal plane, their light exit openings pointing in different directions. This enables targeted lighting that can be individually adjusted and adjusted from module to module, so that several objects, buildings, parts of buildings or floor areas can be illuminated from a lamp mast.

An advantageous embodiment of the invention provides that the module has a horizontal cross section corresponding to the shape and dimensions of the base of the lamp mast. The cross sections of the module and the lamp mast are preferably the same and thus form a structural and optical unit. This creates an aesthetic, closed outer shape of the lamp mast, without protruding parts, which also shows the advantage of a low conspicuity in the cityscape and a low susceptibility to pollution.

Another advantageous embodiment of the invention is characterized by a cambered lid arranged on the top of the uppermost module arranged on the lamp mast, which takes up the cylinder base of the module, which closes the through opening on the top and, if appropriate, the fastening devices in a watertight manner, and by means of the cambering for example, the rainwater can drain off.

In a further advantageous embodiment of the invention, seals for cable feedthroughs are arranged in the leadthrough openings, so that if water enters one of the upper modules, the modules arranged underneath and the lamp mast are protected from water ingress. Another advantageous embodiment of the invention provides that the base of the lamp mast is circular and the lamp mast is a cylinder. Such a shape is easy to manufacture, as a result of which the modules, which are preferably to be made of cast aluminum, can be easily manufactured and are therefore inexpensive.

Another advantageous embodiment of the invention provides that the sector-shaped light outlet opening can be closed by a glass that simulates the outer contour of the module so that the glass also lies in the plane or the curved surface of the outer contour of the lamp mast.

An additional, advantageous embodiment of the invention provides that the module has at least one further, sector-shaped cutout, which can be closed by a inspection flap which is flush with the outer contour of the module, so that the interior and in particular the illuminant, the reflector and the slats of the cutout that can be closed by the inspection flap is accessible, exchangeable and adjustable.

In an advantageous embodiment of the invention, the module thus has two cutouts, namely the one which forms the light exit opening for inserting the glass and the other which represents an inspection opening and is closed with the inspection flap.

An additional, advantageous embodiment of the invention provides that the module on its underside facing the lamp mast has a support base formed by a circumferential shoulder, in which the lead-through opening and the fastening device are arranged to form a further module, the support base being one in its horizontal cross section corresponds to the reduced cylinder base area of the module, so that a circumferential shadow gap is created in connection with the upper end of the lamp mast arranged below the module or the upper side of a module arranged below it. A further advantageous embodiment of the invention provides that a camera can be arranged in the interior of a module instead of or in addition to a lamp.

Another particularly advantageous embodiment of the invention provides that instead of the lead-through openings, corresponding electrical interfaces, such as corresponding plug connections or electro-optical couplings, are arranged on the top and bottom of the module, so that no cables are required to replace individual modules. Connections, but only the screw connections and the plug connections must be loosened. In addition, the use of plug connections allows the installation of a bus architecture, for example in the case of several cameras arranged in different modules and observing in different directions.

An advantageous embodiment of the invention provides that at least one reflector is integrated in the module, so that lamps can be used without their own reflectors. An advantageous embodiment of the invention provides that the reflector is integrated in the inspection flap or is attached to the inspection flap.

Another advantageous embodiment of the invention provides that the module is connected to the mast and / or to another module by means of screw bolts, the screw connection preferably being accessible through the inspection flap, so that defective or maintenance-requiring modules can be easily exchanged is. The fastening devices are thus preferably detachable screw connections, consisting of screws and corresponding threaded holes, so that the module is connected to the lamp mast and / or to a further module by the screw connection. Another advantageous embodiment of the invention provides that the interior is, for example, divided horizontally, so that a ballast electronics, a transmitter or a receiver, for example for the transmission of the Data and the remote control of a camera can be arranged separately from the illuminant and / or the camera in the lower region of the housing.

An advantageous embodiment of the invention provides that the horizontal opening angle of the light exit opening and preferably also of the cutout is less than 150 °.

In an advantageous embodiment, the lighting device with the illuminant, a lamp housing receiving the illuminant with the lamp housing carrying the lamp housing, form both a technical as well as an optical and aesthetic unit and form a set from a technical point of view, the lamp housing as a module that is fitted and removable on the lamp housing which module has at least one interior receiving at least one lamp and, over part of its outer circumference, a sector-shaped cut-out opening, the module at its lower end on the underside facing the lamp mast and at its upper end on the top facing away from the lamp mast Has feed-through opening, each with a fastening device for a further module of the same design, the feed-through openings being aligned with one another and the fastening devices on the top top and bottom are designed to correspond to each other.

WAYS OF CARRYING OUT THE INVENTION:

A module 1 shown in FIG. 1 consists of a module housing 2 made of cast aluminum, which has a sector-shaped light exit opening 3 and a cutout 34 which can be closed by an inspection flap 4 and which is preferably also sector-shaped. The module 1 is designed closed on its upper side 5, 5 'or at its upper end and on its underside or lower end, so that the module housing 2 is in principle designed as a tube. At its lower end, facing for example a lamp mast 21 shown in FIG. 3, the module housing 2 has a circumferential shoulder 15 which forms a support base 16, the cross section or diameter of which is smaller than the cross section or by the inwardly projecting depth of the shoulder 15 Diameter of the module housing 2 above the shoulder 15. The light exit opening 3, which is also formed by a sector-shaped cutout 3 within the module housing 2, can be closed by a glass 6.

The module 1 has on its top 5 and on the support base 16 corresponding fastening devices, which are detachable screw connections 14, consisting of screws and corresponding threaded holes, so that the module 1, 1 ', 1 ", 1'" with the lamp mast 21 , 22, 28 and / or with a further module 1, 1 ', 1 ", 1'" is connected by such screw connections 14. In this way, several modules of the same type can be arranged detachably one above the other, the assembly on the top of a lamp mast 21, 22, 28 likewise being carried out with screw connections guided through the same connections in the support base 16.

Feed-through openings 11 and 12, each arranged on the upper side 5 and on the support base 16, serve for the implementation of cable connections for the electrical power supply of the fluorescent tube 18 arranged in the interior 31. The fluorescent tube 18 is carried by a lamp holder 20, on which a further Ballast 19 is arranged. Behind the fluorescent tube 18, on its side facing the inspection flap 4, a gold-vapor-coated or other highly reflecting reflector 10 is arranged. In the direction of the sector-shaped light exit opening 3 in front of the fluorescent tube, an adjustable lamella diaphragm 17 is arranged as glare protection. The screw connection 14, the reflector 10, the ballast 19, the lead-through openings 11 and 12 as well as the lamella cover 17 and the fluorescent tube 18 can be seen and reached from the inspection flap 4 and through the inspection opening 34.

In order to easily enable the rotation of several modules with one another in a horizontal plane, the threaded holes of the screw connections 14 for receiving the corresponding screws can lie on a bolt circle arranged centrally around the center of the support base 16, on which the threaded holes are arranged at equidistant arc intervals. -The through the circular cylindrical base surface of the module housing 2 with a smaller diameter replicating support base 16 in connection with the through the circumferential shoulder 15 and the top 5 ^{1 of} the upper end of a module V arranged below a shadow gap 13, which the otherwise smooth outer surface of the invention Lighting device interrupts and forms an aesthetic support for the eye of an observer. A cambered cover 7 is mounted on the top 5 of the top module 1 arranged on a lamp mast 21, 22, which closes the through opening 11 on the top 5 and ensures that rainwater runs off due to the curved surface.

Likewise, the cross section of the module or modules and the cross section of the lamp mast can be square or pentagonal or hexagonal and thus be designed as a polygon, but the cross sections are the same, so that the outer contour of the module and lamp mast merge into one another.

Figure 2 shows the module of Figure 1 in a horizontal cross section from above. The reflector 10 limits the radiation angle of the fluorescent tube to the opening angle of the sector of the light exit opening 3, as a result of which the light yield is significantly improved compared to all-round radiation. The glass 6 and the inspection flap 4 are embedded flush with the outer surface by means of a cranked, preferably circumferential stop 9 for the glass 6 and on a cranked, likewise preferably circumferential stop 8 for the inspection flap 4. The sector-shaped light exit opening 3 preferably has an opening angle of 120 °.

FIGS. 3 and 4 show lighting devices in which one or two modules 1 are arranged on a lamp mast 21 or 22. The lamp mast 21 in FIG. 3, which for example represents a bollard light, is also modularly extended by the lamp mast 22 in FIG. 4, the individual modules being separated from one another by shadow gaps. In the module 1 shown in FIG. 5, two individually adjustable spot reflectors 24 and 25 are arranged behind a lamella cover in the interior 31. Accessible from the inspection flap 4 through the inspection opening 34, the spot reflectors can be precisely aligned after the module 1 has been installed, for example on the tip of a lamp mast 28 shown in FIG. A ballast 26 is arranged below the spot reflectors 24 and 25 in the interior 31 of the module housing 2. As in FIG. 1, the modular structure is illustrated in FIG. 5 by a module 1 'arranged under the support base 16 of module 1.

FIG. 6 shows how the spot reflectors 24 and 25 are arranged in the interior 31 of the module 1 without the outer, circular cylindrical shape being disturbed by protruding parts or the like.

FIG. 5 a shows an assembly of a module 1 with two differently orientable reflectors 27 for facade illumination. The reflectors 27 are arranged behind a slat diaphragm 33 with individually adjustable slats, so that both the glare effect and the distribution of the diffuse light through the slats can be precisely controlled.

The module 1 shown in FIG. 5b is equipped with a wallwasher reflector 23 for facades and street lighting.

The lighting device shown in FIG. 7 consists of two modules 1 and 1 'arranged on a lamp mast 28, the separation between adjacent modules again being recognizable by the shadow gaps 13.

FIG. 8 shows a vertical section through a module 1 which is equipped with a reflector for street lighting 29. A ballast 26 is arranged below the reflector for street lighting 29. FIG. 9 shows a horizontal section through such a module 1 equipped with a reflector for street lighting 29. No parts protrude here either of the reflector for street lighting 29 beyond the circular cylindrical shape of the module 1.

The module 1 shown in a vertical cross section in FIG. 8a is equipped with a camera. By installing a camera in a module 1, it is better protected against dirt and vandalism and is not noticed in particular when monitoring objects, for example at sensitive points in the cityscape in public space.

Figure 10 illustrates the flexible, modular structure of the lighting device according to the invention. Four modules 1, 1 ', 1 "and 1"' are arranged on a lamp mast 31, which can independently perform different functions, for example for street lighting, for facade lighting, for lighting an entrance area and for monitoring the entrance area ,

Depending on the intended use and the function to be performed, a different outer diameter of the modules 1, 1 ', 1 ", 1'" is required to maintain the closed, particularly preferred circular cylindrical shape of the modules and the lamp mast, depending on the configuration of the modules, which on the same diameter as a module masts 21, 22, 28 are mounted. Some of the height-diameter ratios which are particularly conducive to an aesthetically slim form are shown in FIGS. 3, 4, 7 and 10. The height designated in FIG. 3 is 1240 mm with a diameter di of 120 mm. The height denoted by l ₂ in FIG. 4 is 3840 mm with a diameter d ₂ of likewise 120 mm.
