LIGHTING SYSTEM

The present invention relates to a lighting system with a plurality of Be¬leuchtungsvorrichtungen in the form of spotlights for Gebäudeinnenraum- or Außenraumbe¬ illumination, each lighting device is preferably provided with a punctiform light source preferably in the form of an LED and a light source associated lens arrangement.

So-called downlights or ceiling spotlights are relatively small-format spotlights, built on or in building ceilings or ceiling or furniture panels or built on, or if necessary, but can also be suspended or mounted pendulum and a limited space as evenly as possible should illuminate. With such downlights in the form of recessed, surface-mounted or pendant luminaires, for example, tables can be aimed at from above and evenly illuminated without disturbing the room ambience. On the other hand, such emitters are not only used for illuminating limited areas such as tables, but often also used in larger numbers to illuminate entire rooms, in which case different areas of space are often to be illuminated differently. In this case, the radiators are often arranged in a regular matrix-shaped grid or even in a regular line arrangement in the immediate vicinity of one another, so that they are perceived as a uniform illumination system. The spotlights can be dabeials ceiling spotlights, wall spotlights or floor spotlights are formed, or on or in furniture on or grown.

However, in addition to the above-mentioned building-related applications for the illumination of building interior spaces, such radiators can also form outdoor radiators for illuminating outdoor spaces, parks and traffic routes, for example as walkway radiators or street lights, for example mounted on a mast or bollard or in a tunnel as a tunnel light.

Due to the diverse uses of such emitters these inlichttechnischer regard must often meet quite different requirements and provide different light distribution curves depending on the requirements. Especially if several such Down¬lights are combined in a uniform arrangement, for example in the form of a Deckenleuchten¬felds, it would be desirable to be able to provide different light distributions for different areas, but this nonetheless maintain a total uniform appearance of the lighting arrangement to be able to.

If such spotlights operated with point-shaped light sources in the form of LEDs, the desired light distributions are controlled by reflectors and / or lens arrangements, which are characterized in terms of their shape, however, by the Lichtverteilungen to be achieved and thus lead to different light distributions to different appearance images. In addition, in such emitters with LEDs, which in themselves make use of the known advantages of LEDs, such as low energy consumption and long lifetime, the heat or cooling problem arises. Since the LEDs produce a relatively large amount of heat and thus require cooling devices, different lighting tasks, which for example require different powers, can lead to differently sized or differently designed cooling devices, which in turn can influence the uniform appearance of such radiator arrangements.

For example, DE 20 2007 007 046 U1 shows a recessed ceiling spotlights, for the light source as an LED should be provided behind the sunk in the ceiling, a reflector is arranged to selectively emit the light. In addition, over the mounting surface protruding Lichtleitringe are provided which not only nachunten the light emitted by the LED light, but also laterally on the ceiling along. DE 20 2009 005 777 U1 also shows a built-in lamp with an LED as the light source, the LED in FIG

Focus of a reflector should be arranged. A heatsink seated on the back of the reflector is integrated into the spotlight housing in the form of a thin plate, allowing for adequate cooling performance only at lower powers. Furthermore, the KR100946548 B1 shows an LED downlight in whose reflector the LED is inserted from the rear.

EP 20 31 296 A1 shows an integrated into a ceiling panel lighting device with an LED as the light source, which is preceded by a lens to completely capture the abgegebannte from the LED light and focus on a focal point. As a result, the light exit opening to be provided in the ceiling panel can be made very small since the light is focussed through. However, this design of the illumination device from the visual appearance no longer corresponds to a classic downlight. In addition, no conventional mounting as conventional downlights possible.

The present invention has for its object to provide an improved Beleuchtungs¬ system of the type mentioned, the disadvantages of the prior art avoids the latter and advantageously further develops. In particular, an arrangement kleinbau the emitter in the form of downlights is to be created, which are in terms of their Licht¬verteilungskurven easily adaptable to different tasks and yet a uniform appearance of the radiator despite different Lichtverteilungskurvenwahren.

This object is achieved by a lighting system according to claim 1. Preferred embodiments of the invention are the subject of the dependent Ansprü¬che.

It is therefore proposed to modularly construct the lens arrangement associated with the light source in order to be able to easily exchange individual lens components and to be able to combine different lens components in a variable manner. According to the invention, the lens arrangement has at least two separate lens components arranged nested one inside the other, comprising an inner lens seated on the light source and an outer lens encircling the inner lens. In this case, the inner lens does not mean the usual dome-shaped cover hood or coupling-out lens of the light source itself, but a lens separate from the Auskkoppellinse the light source, in front of the light source switched lens. By virtue of the arrangement of the inner and outer lenses which is overturned or intermeshed, an overall small-sized, low-height lens arrangement can be created despite the number of lenses having a large variability with regard to the light distribution curves that can be generated by combining different lens components. At the same time, it is possible to ensure a consistent external appearance, since the combination of different lens components makes it possible to vary the light distribution curves that can be generated without varying the external appearance, since there are greater degrees of freedom with regard to the design of the lens components. The lens arrangements of the plurality of illumination devices combined to form a radiator arrangement are designed differently from one another in order to produce different illumination characteristics for different radiators, the outer lenses of all radiators of the radiator group having at least approximately identical outer contours, so that the radiator arrangement has a uniform, external appearance Appearance despite different light distribution characteristics receives.

In a further development of the invention, the outer lens may be formed as a removable module, the releasable, preferably tool-free operable quick-fastening means, insbeson¬dere locking locking means for locking the lens. As a result, in the case of assembly, the respective desired outer lens component can be mounted in a simple manner, if necessary also the outer lens component can subsequently be removed and replaced by another lens component in order to achieve a different light distribution curve, depending on the installation situation or changing requirements. The exchangeable outer lenses have at least approximately identical outer contours in order to maintain the consistent external appearance. In order to vary the light distribution characteristic, inner contours of the exchangeable outer lens modules may vary and / or the respective inner contours

Lens can be changed.

Alternatively or additionally, the inner lens can be designed as a removable module and similar detachable, preferably tool-free manageable quick-fastening means have, so that the inner lens can be varied or changed to verschie¬den lighting lighting tasks justice. However, the exchangeability and variability of the outer lens component is preferred because it is easier to assemble or disassemble, since no other system components have to be exchanged in advance. Thus, a consistent preassembly assembly comprising the LED and the inner component can be used in particular Use lens, then depending on the Konfigurati¬onsbedarf the appropriate outer lens is placed.

In an advantageous embodiment of the invention, the inner and outer lenses, viewed from their cross-sectional shapes have different contours. In particular, can be used in a from the outer contour forth angular outer lens from the outer contour ago round, in particular circular inner lens. The meshing angular and round lenses allows great freedom in the variation of the radiation characteristic, but above all Din¬gen but also a favorable Aneinanderetzbarkeit multiple emitters. By means of an angular outer contour defined by the outer lens, for example cubic or honeycomb-shaped, a plurality of radiators can be arranged more or less directly adjacent to each other in the manner of a light track or light strip, which is not the case with conventional radiators with a round outer contour.

However, such an angular outer contour is not mandatory for the outer lens. It is also possible to select other outer contours depending on the application, for example free-form contours such as floral or cloverleaf contours, hybrid shapes of angular and circular contour shapes such as D-shaped or mushroom-shaped contours, contours resembling geometric basic shapes such as ovals or ellipses or also other regular or irregular symmetrical contours or asymmetrical freeform contours. Advantageously, however, the outer lens has a regular, well-contoured contour.

In particular, the outer lens has circumferentially an outer contour in the form of a regular polygon, preferably rectangles or hexagons, wherein the Lichtaustritts¬ surface forming end face, which is formed on its outer contour corresponding polygonal, miteinem round, preferably rotationally symmetrical lens portion is provided. As a result, a uniform, harmonious light distribution can be achieved despite angular outer contouring.

In a particularly advantageous embodiment of the invention, the outer lens, the Au¬ßenkontur a regular prism with flat side surfaces and an outside ebe¬nen end face, in particular in the form of a cube, have. As a result, a plurality of radiators can be cube-like juxtaposed, so that there is a great deal of freedom in the configuration of lighting systems in the form of ceiling radiators, for example. In particular, a plurality of radiators in the form of a row or even a plurality of rows can be positioned directly next to one another, so that overall the appearance of a matching light is produced, wherein in an advantageous development of the invention, several radiators may have differently radiating lens arrangements with preferably at least approximately identical outer contours in order to differentiate To cause light distributions. For example, in the case of a single-row line arrangement of a plurality of emitters in a corridor, it is possible for emitters located in the area of doors to effect a light distribution illuminating the floor in a spot-like manner in order to prevent the persons coming out of the door from blinding, while between doors arranged radiators, ie where the corridor is bounded by walls, asymmetric light distribution is provided to evenly illuminate the walls. If, for example, a three-row ceiling radiator arrangement is provided, the spotlights arranged in the middle row can illuminate the floor in a potted manner, while the radiators arranged in the left and in the right row are directed onto the right or left wall side. Despite such different, symmetrical or asymmetrical radiation characteristics of the lenses, the radiators may advantageously have more or less identical outer contours, so that a uniform appearance is ensured and the individual radiators in the switched-off state are not to be regarded as causing different light distributions.

Are in the aforementioned manner no angular, but round or otherwise shaped freeform contours realized on the outside of the lens, the Außenkonturanstelle the aforementioned regular prism advantageously forms a corresponding, at least approximately cylindrical body with at least approximately vertical flanks, for example in the form of an im Cross-cloverleaf shaped cylindrical body, here as well as in the case of the aforementioned prism body a slight oblique employment of seitlichen flanks may be provided in the manner of a slight conical or pyramidal shape to act as Entformungsschräge or to simplify installation in the light carrier.

The light exit surface of the outer lens can in this case be formed by the outer plane face of said prismatic or cylindrical body, wherein the light entry surface of the outer lens formed from the inside of said end face and arched spielsweise, preferably formed rotationally symmetric curved , In this way, on the outside, a completely smooth, cubic structure is achieved, which allows a uniform, uniform appearance of composite emitters, but on the other hand nonetheless achieves the desired lens effect. By varying the mentioned light entry surface of the outer lens, different symmetrical or asymmetrical distribution characteristics can be achieved. Depending on the lighting task, instead of the rotationally symmetric curvature at the light entry surface, free-form surfaces or other shaped surface forms that effect the desired light distribution can also be realized. Nevertheless, the different outer lenses, whose light entry surface varies from one another, advantageously have the same outer dimensions and contours, so that the outer appearance of corresponding illumination systems remains uniform, even if the individual radiators provide different light distributions.

Due to the modular design of the radiator and a plurality of radiators can be implemented um¬fassende radiator arrays or arrangements, which reduce the glare. Instead of a single radiator, which must provide a corresponding high light intensity, many fainter radiation emitters can be used reduce the dazzling effect, but nevertheless provide the necessary light intensity in total.

The inner lens may in principle have different designs and shapes. In an advantageous embodiment of the invention, the inner lens - roughly speaking - a kelch¬förmiger solid material body, the light source side may have a napf- or blind hole Lichtein¬ entrance recess, which has a cavity limited, in which the light source is angeord¬net. The entry surfaces of the inner lens formed by the blind-hole-like light entry recess advantageously direct at least a portion of the incoming light onto the lateral surface of the lens, which is designed to be totally reflective or mirrored in order to direct the light from the lateral surface onto the light exit surface of the lens. The light exit surface is in this case formed by the end face of the inner lens, which lies opposite the aforementioned Lichtein¬trittsausnehmung.

In order to achieve a good mixing of the light, for example to avoid light spots or color spots on the surface to be irradiated, the aforementioned Lichtein¬ entrance recess may have a central entrance surface area, which directs the light entering there directly to the light exit surface of the lens, while a on The light in the aforementioned manner directs the light onto the lateral surface in the aforementioned manner to the central entrance surface area of the adjacent outer entrance area. Advantageously, in this case the light entry recess and the jacket surface are configured in such a way that the light beams directed directly onto the light exit surface and the light beams deflected on the jacket surface cross over before reaching the light exit surface. In order to enhance this effect of mixing, in a preferred embodiment of the invention, the lateral surface of the lens and / or the aforementioned central entrance surface may be provided with a surface structuring in the form of a faceting comprising a multiplicity of facets. Advantageously, the facets can be designed in such a way that the light beams deflected by the lateral surface cross one another before reaching the light exit surface and / or the light beams directed from the entry surface directly to the light exit surface also cross each other before reaching the light exit surface.

The inner lens and / or the outer lens may, depending on the lighting task and the light distribution characteristic to be filled, have different shapes and contouring, for example as a free-form lens, also asymmetrically radiating free-form lens.

In order to achieve a simple installation and configurability with a simultaneously small-sized lens arrangement, a further development of the invention provides a common lens holder for the lens components of the lens arrangement on which the inner lens and the outer lens are mounted. Preferably, the common lens holder hereby has inner and outer holding surfaces or elements, so that in an advantageous development of the invention, the outer lens can be mounted on an outer peripheral surface of the lens holder and the inner lens on an inner peripheral surface or on a surface projecting from the inner peripheral surface. The common lens holder advantageously extends between the inner lens and the outer lens placed over it and holds the two lenses in exact position with respect to each other. In this way, with a compact arrangement, easy assembly and with few components, an exact positioning of the two lens components relative to one another can be achieved.

In an advantageous embodiment of the invention, the lens holder is formed overall sleeve-shaped, wherein on the one hand on its outer peripheral surface locking means, for example in the form of a locking groove or a projecting locking bead for the outer lens and on its Innen¬umfangsfläche positioning and / or attachment means for the inner lens possess can.

Advantageously, said lens holder is also used for holding a cooling module provided on the rear side of the LED. For this purpose, the lens holder can comprise a retaining section protruding above the light source, preferably also sleeve-shaped, for holding the supply and / or cooling module.

In order to ensure a simple assembly, it is advantageous if the lens holder in the development of the invention has a plug-in recess open towards the back of the light source, through which the inner lens can be moved from its rear side to its intended setpoint position within the Lens holder can be inserted, and further to the front side protruding holding means has, preferably in the form of a sleeve-shaped holding portion in order to attach the outer lens from a front side can.

To summarize a plurality of radiators to a radiator array, easy to assemble and close to each other to order, is provided according to a further aspect of the present invention, a plurality of radiators of the type described above to arrange a common carrier in a preferably regular grid , In this case, the common carrier advantageously comprises a number of through-hole recesses corresponding to the number of emitters, which in each case is adapted to the non-round, in particular rectangular, outer contour of the outer lens. In particular, all Durchsteckausnehmungen are contoured equal, even if emitters are stored with different light distribution characteristics on the same carrier. The different, symmetrical or asymmetrical light distributions are achieved via differently contoured lenses, which nevertheless have the same outer contour to which the passage openings are adapted.
