Lighting devices are well known. Such lighting devices comprise a housing having a substantially plate-shaped base body. Arranged on the main body is a cooling element which comprises cooling fins extending substantially perpendicularly from the upper side of the main body and extending from the outer circumference of the main body in the direction of the longitudinal axis of the main body. On the housing, a light source is further arranged. Such lighting devices are for example in the DE 20 2008 007 490 U1 , of the US 2015/0070911 A1 , of the EP 2 539 632 B1 , of the CN 102518991 A or the generic WO 2014/027755 A1 described. Particularly disadvantageous in all these lighting devices in practice, the structural design itself has been found. Thus, the lighting devices or housing a horizontal base body with the substantially vertically wegerstreckenden cooling fins no measures before, with which a clogging of dust, dirt or the like impurities could be avoided or at least reduced. The result is damage to this lighting device due to greatly reduced cooling, which can sometimes lead to complete failure of these lighting devices. To counteract this, these lighting devices must be maintained at regular intervals and getting cleaned. The resulting effort is often greater when such lighting devices are mounted in premises with large room heights, such as in exhibition halls. In most cases, then additional equipment, such as lifting platforms, etc., necessary. The safety precautions for the maintenance and cleaning personnel inevitably increase. The consequence is a considerable cost in the operating costs of such lighting device as a whole.

In the following description of various embodiments of a lighting device 10 according to the invention, corresponding, identical components are each provided with identical reference numerals.

The lighting device 10 according to the invention advantageously finds use for illuminating interior or exterior premises of a building, in particular premises located inside buildings. In addition, the lighting device 10 according to the invention can be very preferably in indoor spaces and preferably use with large room heights. For example, the lighting device 10 according to the invention is suitable for use in industrial building halls, exhibition halls, gymnasiums or the like halls.

The in the Fig. 1 to 9 The main body 12 is essentially plate-shaped, has an approximately circular shape in plan view in this embodiment and has an upper side 14, an outer circumference 16 and a lower side 18.

The lighting device 10 according to the invention also has a cooling element 20, which is arranged at least partially on the upper side 14 of the main body 12. The cooling element 20 comprises cooling ribs 22 which extend substantially perpendicularly from the upper side 14 of the base body 12. The cooling ribs 22 also extend from the outer periphery 16 of the main body 12 in the direction of the longitudinal axis 24 of the main body 12.

The lighting device 10 according to the invention further comprises a holding or supporting element 26 which is fastened to the underside 18 of the main body 12. The holding or carrying element 26 has at least one light-emitting means 28. In the present embodiment of the lighting device 12 according to the invention, the holding or supporting element 26 is advantageously designed as an LED board, from which a plurality of light-emitting elements (LEDs) is accommodated. For example, an LED board that delivers different light outputs (150 W, 200 W and 250 W) with different power supplies can be used.

As in particular from the 4 and 5 shows, the top 14 of the plate-shaped base body 12 is formed in the embodiment of the lighting device 10 according to the invention such that incident on the top 14 / r dust, dirt or other contaminants and / or impinging water or the like media in the direction of its longitudinal axis 24 out to the outer periphery 16 and discharged is / are. The discharge takes place via the outer circumference 16 or an adjacent area, in particular automatically.

Dust, dirt or the like in the air containing impurities can thus not catch on the top 14 of the body 12 of the entire lighting device 10 and / or accumulate. The cooling is not impaired, but remains unchanged over the entire life of the lighting device 10 according to the invention. Water, which is possibly used for cleaning the lighting device 10, for example, can also flow away from the center of the upper side 14 of the main body 12 or the lighting device 10 towards the outer circumference 16 and over the outer circumference 16.

Accordingly, as from the 4 and 5 can be seen, the top 14 of the plate-shaped base body 12 in cross-section approximately conical, conical, conical or frustoconical. This is most evident in a cross section - as in the Fig. 5 - Recognizable, which is defined by a plane defined by the longitudinal axis 24 plane, for example in the leaf level.

Without being shown in detail, the upper side 14 of the plate-shaped main body 12 may be of the same shape, in cross-section, for example, such as convex, hemispherical, hemi-spherical, cup, pot, bowl, or the like.

According to the 4 and 5 the plate-shaped base body 12 thus has a thickness in cross-section, which decreases in the direction of the longitudinal axis 24 towards the outer periphery 16. Alternatively, it is possible to keep the thickness of the main body 12 substantially equal or constant (not shown), but connected with one then in purchase to be increased weight of the lighting device 10th

In addition, the top 14 of the base body 12 is provided with a coating or a coating (not shown) made of plastic, which is characterized in particular by dust, dirt and / or water-repellent material properties. By such a coating, the discharge of impinging on the top 14 of the body 12 dust, dirt or the like impurities and / or water or similar media, as previously detailed, supported on the outer periphery 16 in addition. Alternatively or cumulatively, such a coating may have electrostatically chargeable material properties in order to counteract an accumulation of dust, dirt or other contaminants on / on the upper side 14 of the base body 12.

Preferably, the coating or like coating is polytetrafluoroethylene (PTFE), polyamide (PA), polyimide (PI) or polyoxymethylene (POM), polypropylene (PP) or polysulfone (PSU), and / or a combination thereof.

In an alternative or cumulative embodiment, the upper side 14 of the main body 12 may be provided with a surface structure, in particular a micro- or nanoscopic surface structure, which counteracts the adhesion of dust, dirt or other contaminants and / or water or similar media in accordance with the lotus effect ,

In the embodiment of the lighting device 10 according to the invention Fig. 1 to 9 is / are the outer periphery 16 and / or the bottom 18 of the base body 12 in an outer periphery 16 adjacent region 30 of the body 12 at least partially surrounded by the cooling element 20 with the cooling fins 22. After the main body 12 itself is circular, the region 30 is given a strip-shaped design and has the shape of a circular ring.

In the present case, the cooling fins 22 completely surround the outer circumference 16 and the underside 18 of the main body 12 in the region 30 of the base body 12, which extends approximately to the holding or support element 26. The area for the transmission and removal of heat generated by the at least one light source 28 can thus be considerably increased in a simple manner. The size of the regions of the cooling ribs 22 on the outer circumference 16 and on the underside 18 is determined by the operating conditions, spatial conditions, etc.

The cooling ribs 22 are in the region 30 beyond the outer periphery 16 of the base body 12 and thus virtually completely or partially freikragend. In addition, the respective adjacent cooling fins are spaced from each other by a gap 32.

The vertical arrangement of the cooling ribs 22 and the gap 32 between each two adjacent cooling ribs 22 can be used together with the created by the cooling fins 22 large area in the region of the outer periphery 16 of the base body 12 and thus an outer region of the entire lighting device 10, a chimney effect , A fast, efficient and above all targeted removal of heat to the side and / or away from the lighting device 10 and cooling is possible.

Accordingly, only the surface of the cooling fins 22 in the annular region 30 of the lighting device 10, which in the Fig. 9 partially aborted and shown schematically, a cooling capacity of about 220 W. This would allow operation even with complete dusting of the top 14 of the body 14, but this is excluded due to the inventive design anyway.

To increase the stability is in the embodiment of the Fig. 1 to 9 provided on the outer circumference 34 of the cooling fins 22, a circumferential ring 36 or the like clip.

The cooling fins 22 of the cooling element 20, which are substantially extend vertically away from the top 14 of the body 12, corresponding to the Fig. 2 . 4 . 5 and 8th a mutually different length. The cooling fins 22 therefore have two mutually different lengths. Thus, the one cooling ribs 22 extend from the outer circumference 16 close to the longitudinal axis 14 of the base body 12 reaching. The other cooling ribs 22 are designed shorter by about 2/3 third and also extend from the outer periphery 16 starting in the direction of the longitudinal axis 24. In this respect, a cooling rib 22 changes in length and a cooling rib 22 with a smaller length, ie the cooling ribs 22 with each other different lengths are each arranged adjacent. This different length results from the shape of the body and consequently the place on / on the top 14 and a maximum exploitable cooling.

Like that 4 and 5 can be removed, have the substantially vertically extending away from the top 14 of the body 12 and extending from the outer periphery 16 of the body 12 in the direction of the longitudinal axis 24 of the body 12 cooling fins 22 a height which primarily for reasons of weight saving in the direction of the Outside circumference 16 decreases towards the longitudinal axis 24 of the base body 12.

In the embodiment of the lighting device 10 according to the invention is corresponding to the Fig. 5 further provided a film 38 or a pad with thermal and / or electrical insulating property / s. The foil 38, which is a thermoplastic heat conducting foil or a thermoplastic heat conducting pad, is arranged between the plate-shaped main body 12 and the holding or carrying element 26.

In this way, the use of, for example, a thermal grease can be completely dispensed with. This in turn can be significant savings in manufacturing and maintenance and operating costs in total, not least as a result of high dimensional and assembly accuracy, a simplified and reproducible processing and a missing Maintenance need, received.

On the holding or supporting element 26 with the at least one light-emitting means 28 is still a support frame member 40 according to the 10 and 11 fixable. The support frame element 40 comprises at least one optical element 42. For example, if necessary, about 180 such optics 42 may be provided on the support frame member 40 on the lighting device 10 associated with the support or support member 26. Since many different optics 42 can be used, in addition a very great versatility and flexibility in the final embodiment of the lighting device 10 according to the invention can be obtained

In the embodiment of the lighting device 12, based on the Fig. 1 to 9 is presented, the holding or support member 26 are attached to the base body 12 via screws 44 and the support frame member 40 in turn on the support or support member 26 by means of screws 46. Both can preferably be done in an assembly step. Instead of a screw holding or supporting element 26, body 12 and / or support frame member 40 are equally connected via a plug-in and latching or Bayonette connection, etc., releasably connected to each other.

The base body 12 is further associated with a power supply and / or control device 48, by means of which the lighting means 28 of the holding or supporting element 26 via a line or a cable (not shown) is operable. The line or the cable is (through) through a passage opening 50 in the body of the power supply and / or control device 48 to the holding or support element (durch-). Coming back to the Fig. 2 . 3 . 7 and 8 , the base body 12 and the power supply and / or control device 48 are arranged at a spatial distance from one another in order to preclude thermal coupling.

In the illustrated embodiment, the power supply and / or control device 48 received by a fastener 52 for this purpose. The fastening element 52 is substantially U-shaped, in the form of a bracket, designed and attached to the base body 12 by means of screws 54.

In the embodiment of the Fig. 2 . 3 . 7 and 8 the fastening element 52 is formed in two parts. The hinge 56 is thus provided between another bracket which is fixed to the ceiling, wall or the like of a room. The pivot 56 acts between the two brackets.

Furthermore, the fastener 50 may be provided with a latching device 58 to hold a once-aligned lighting device 10 in position.

In the embodiment of the lighting device 12 according to the Fig. 1 to 9 the plate-shaped base body 12 and the cooling element 20 and the cooling fins 22 are preferably formed as an integral component and thus in one piece. Without being shown in detail, however, the base body 12 and the cooling element 20 may readily be formed as separate components, which are then to be assembled, assembled and fastened together.

The plate-shaped base body 12 and / or the cooling element 20 and / or the supporting and holding element 26 with the at least one light source 28 and / or the support frame element with the at least one optical element is / are made of metal, in particular of non-rusting or corrosion-resistant metal , preferably of aluminum, most preferably of an aluminum alloy 230D, steel, stainless steel, titanium, an alloy thereof and / or a combination thereof.

Without being further elaborated in detail, can / can plate-shaped base body 12 and / or the cooling element 20 are preferably produced by a casting or die casting process. It is likewise conceivable to use a generative production method, in particular by means of 3D printing, direct metal laser sintering (DMLS), selective laser melting (SLM), selective laser sintering (SLS), additive layer manufacturing (ALM), or electron beam melting (Electron Beam Melting (EBW)) to produce the plate-shaped base body 12 and / or the cooling element 20.

The present invention is not limited to the illustrated embodiment lighting device 10 and / or the method. Without being shown in detail, it is possible to individually and arbitrarily combine the embodiments of the lighting device 10 according to the invention and their individual components with one another or with one another. Thus, it is readily conceivable, the presented, in part very different embodiments of the lighting device 10 according to the invention and their design and arrangement to design arbitrarily. In addition, it is possible to provide the components in any number, arrangement, shape and size. For example, it is possible not to form the holding or supporting element 26 as an LED board and / or the at least one light-emitting means 28 as a light-emitting element (LED).
