Description

Technical area:

The invention relates to a lighting device with a light source and a lamp housing accommodating the light source for a lamp post carrying the lamp housing, according to the preamble of claim 1.

State of the art:

It is known to carry out lighting devices, in particular those for the public sector such as for street, Fußwege- and park lighting, as a arranged on the top of a lamppost bulbs. As a result, a large environment can be illuminated around such a lighting device and the lamp is protected against damage and contamination. A generic lighting device is known for example from German design M 8907946.9. Although an all-round radiation of the light has the advantage of ease of manufacture, since it is sufficient to arrange a light source on the top of the lamppost, but it also has the disadvantage of untargeted lighting of areas that need not be illuminated or not to be illuminated. In addition, such known lighting devices are not suitable for illuminating buildings or objects in public space, since the emitted light radiation due to the large scattering angle is usually not sufficient to obtain a satisfactory illumination, such as a facade.

For the illumination of facades of buildings, it is known to use high-power radiators, which are embedded in the ground, or are arranged on opposite buildings or on poles. However, these known lighting devices have the disadvantage that persons who are located between the high-power radiator and the facade to be illuminated, strongly blinded and that in addition the facades of adjacent buildings are often spoiled by the high-power radiators arranged there, because they are not in the facade insert. The lack of aesthetics allows for the installation of such spotlights on the top of a lamp post only a limited and mostly non-permanent use in urban Area or in public space, especially since additional lighting devices for normal road and street lighting are necessary. The known lighting devices, especially for public roads and roads also have the disadvantage that necessary repairs to the lights, the bulbs or the associated electronics must always be made locally, resulting in high maintenance costs.

From DE 298 07 056 U1 is a bollard for limiting and / or nocturnal illumination of accessible and / or trafficable 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 Light passes through at least one window-like light opening to the outside. In the at least approximately over its entire height hollow bollard body, a first light source and a second light source are arranged, wherein the first light source emits their light substantially upwardly through an end-side light aperture and the second light source emits its light through a second light aperture to the outside, which extends like a ribbon from bottom to top, at least in the lower part of the bollard body.

Furthermore, DE 200 07 434 U1 discloses 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 of the light source emerges substantially horizontally. The light source is arranged in the center of a translucent material consisting, flat Lichtleitkörpers whose light exit surface is arranged in the peripheral region of the bollard housing and its substantially parallel planar surfaces are at least approximately completely mirrored. The light guide body assumes a substantially horizontal position in the vertical bollard housing.

By EP 0903534A a signal lamp with a longitudinal body having a main body and at least one arranged on the body luminous source has become known, in which the columnar base body has at least one rotary joint with an axis of rotation to the at least two sections of the body are mutually rotatable. The axis of rotation of at least one rotary joint is tilted by a predetermined angle with respect to the longitudinal axis of the base body. At the hinge contact means between the at least one lighting device and a power supply are provided, which comprises a limited angle of rotation following wire loop. The main body is rod-shaped or columnar and has a round, triangular or polygonal cross-section.

Furthermore, US Pat. No. 3,868,682 A has disclosed a light column comprising at least partially transparent lighting elements, which each comprise a light bulb and are arranged stack-wise one above the other and which are seated on a base. Each luminous element comprises a transparent cylinder part, which is in each case crossed by fixed supply lines and at one end of which carries an opaque solid partition on which the light bulb and a first connecting device are mounted. At its other end, an access to the light bulb enabling second connecting means is mounted, which is coupled to the first connection means of a lighting element only in one orientation.

Technical object of the invention:

Ways to carry 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 a revision flap 4, which is preferably also sector-shaped. The module 1 is designed to be closed on its upper side 5, 5 'or at its upper end and on its underside or its lower end, so that the module housing 2 is designed in principle as a tube. At its lower, an example shown in Figure 3 lamp post 21 facing the end, the module housing 2 has a circumferential shoulder 15, which forms a support base 16 whose cross section or diameter around the inwardly projecting depth of the shoulder 15 is smaller than the cross section or 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 upper side 5 and on the Aufiageboden 16 respectively corresponding fastening means which are releasable screw 14, consisting of screws and corresponding threaded holes, so that the module 1, 1 ', 1 ", 1"' with the lamppost 21st , 22, 28 and / or with another module 1, 1 ', 1 ", 1"' is connected by such screw 14. In this way, several similar modules can be solvable be arranged one above the other, wherein the mounting on the top of a lamppost 21, 22, 28 is also carried out by the same connections in the support base 16 threaded connections.

Through openings 11 and 12, respectively arranged on the upper side 5 and on the support base 16, serve to carry out cable connections for the electrical power supply of the arranged in the interior 31 fluorescent tube 18. The fluorescent tube 18 is supported by a light fixture 20, which also has a Ballast 19 is arranged. Behind the fluorescent tube 18, on which the inspection flap 4 side facing a gold vapor-deposited or other highly reflective reflector 10 is arranged. In the direction of the sector-shaped light exit opening 3 in front of the fluorescent tube, an adjustable slat aperture 17 is arranged as a glare shield. The screw 14, the reflector 10, the ballast 19, the lead-through openings 11 and 12 and the lamellar aperture 17 and the fluorescent tube 18 are visible from the inspection flap 4 and through the access opening 34 through and accessible.

To easily enable the twisting of several modules with each other in a horizontal plane, the threaded holes of the screw 14 for receiving the corresponding screws on a centrally around the center of the support base 16 arranged bolt circle lie on which the threaded holes are arranged at equidistant arc intervals.

By the circular cylindrical cylinder base surface of the module housing 2 with a smaller diameter replicating support base 16 is formed in conjunction with the by the circumferential shoulder 15 and the top 5 'of the upper end of an underlying module 1' 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. In each case on the upper side 5 of the uppermost, arranged on a lamp mast 21, 22 module 1, a domed lid 7 is mounted, which closes the passage opening 11 at the top 5 and ensures the drainage of rainwater through the curved surface.

Similarly, the cross section of the module or modules and the cross section of the lamp post can be square or pentagonal or hexagonal and thus polygonal, but the cross sections are the same, so that the outer contour of the module and lamp post merge into one another.

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

Lighting devices are shown in FIGS. 3 and 4, in which one or two modules 1 are arranged on a lamp mast 21 or 22. The lamppost 21 in Figure 3, which is for example a bollard, is also modularly extended by the lamppost 22 in Figure 4, wherein the individual modules are separated from each other by shadow gaps.

In the case of the module 1 shown in FIG. 5, two individually adjustable spot reflectors 24 and 25 are arranged behind a lamella diaphragm in the interior 31. Accessible from the access door 4 through the inspection opening 34, the spot reflectors can be precisely aligned after assembly of the module 1, for example on the tip of a lamp post 28 shown in FIG. A ballast 26 is disposed below the spot reflectors 24 and 25 in the interior 31 of the module housing 2.

As in FIG. 1, the modular construction is also illustrated in FIG. 5 by a module 1 'arranged under the support base 16 of the module 1.

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

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

The module 1 shown in Figure 5b is equipped with a wallwasher reflector 23 to the facades and street lighting.

The lighting device shown in Figure 7 consists of two arranged on a lamp post 28 modules 1 and 1 ', wherein the separation between adjacent modules in turn by the shadow gaps 13 can be seen.

Figure 8 shows a vertical section through a module 1, which is equipped with a reflector for street lighting 29. Below the reflector for street lighting 29, a ballast 26 is arranged. FIG. 9 shows a horizontal section through such a module 1 equipped with a reflector for street lighting 29. Again, no parts of the reflector for street lighting 29 collar beyond the circular cylindrical shape of the module 1 addition.

The module 1 shown in Figure 8a in a vertical cross section is equipped with a camera. By installing a camera in a module 1, this is better protected against dirt and vandalism and is especially at the object monitoring, for example, at sensitive points in the cityscape in public space not perceived.

FIG. 10 illustrates the flexible, modular construction of the illumination device according to the invention. On a lamp pole 31 four modules 1, 1 ', 1 "and 1' '' are arranged, which independently can perform different functions, for example, for street lighting, for the facade lighting, for the illumination of an entrance area and for the monitoring of the entrance area.

Depending on the intended use and on the function to be performed, another external diameter of the modules 1, 1 ', 1 ", 1"' is required to maintain the closed, in particular preferred circular cylindrical shape of the modules and the lamp post depending on the assembly of the modules on the same diameter as a module having lamp posts 21, 22, 28 are mounted. Some of the aesthetically slim form particularly beneficial height-diameter ratios are shown in Figures 3, 4, 7 and 10. Thus, the height denoted by I ₁ in FIG. 3 is 1240 mm with a diameter d ₁ of 120 mm. The height indicated in Figure 4 with I ₂ is 3840mm with a diameter d ₂ of also 120mm. The height indicated by I ₃ in FIG. 7 is 5420 mm with a diameter d ₃ of 170 mm. The height indicated by I ₄ in FIG. 10 is 9440 mm with a diameter d ₄ of 240 mm.
