Description

The invention relates to a system for realizing an elongate lamp and a lamp produced by means of the system.

Generic systems relate to a lamp which has at least one, in particular a plurality of mounting rails which are elongated in the longitudinal direction and at least one, in particular a plurality of mounting bodies which are elongated in the longitudinal direction. Typically, the mounting rails are used to fix the lamp to a structure, such as a ceiling. Electrical functional elements of the lamp are usually attached to the assembly body, for example printed circuit boards with LEDs, radio modules, electrical lines and/or operating devices. When installing the lamp, the respective mounting rail is usually first attached to the structure and then the mounting body, which is equipped with at least one of the electrical functional elements of the lamp mentioned, is fixed to the mounting rail, so that the mounting rail and mounting body form an interior space in which the essential elements of the Luminaire are arranged, for example circuit boards, operating devices, contact devices, lines, etc. Typically, mounting rail and mounting body are each formed elongated in a longitudinal direction, preferred the longitudinal extent is at least five times the extent perpendicular to the longitudinal direction. The support rail usually has a cross-section perpendicular to the longitudinal direction, which is open along a vertical direction at a vertical end and is delimited along a transverse direction by two support rail side walls which are connected to one another by a support rail bottom running along the transverse direction and which extend away from the support rail bottom vertically extend. The support rail base and the support rail side walls usually together form an interior or receiving space which is enclosed at least in sections by the support rail side walls and the support rail base and which in this respect is essentially defined by the support rails. The support rail is usually open at at least one of its vertical ends. Support rails of a system, in particular all support rails of a generic system, usually have the aforementioned features. If the lamp to be produced has several mounting rails, for example two, the two mounting rails are connected to one another at their longitudinal ends to form the lamp. They usually form a common receiving space, which extends between the support rail side walls of both support rails and the support rail base of both support rails in an elongated manner along the longitudinal extent of both elongated support rails. Frequently, the two mounting rails are not fixed directly to one another with their longitudinal ends, but are fixed to one another by means of a mechanical coupling. Usually, each of the mounting rails has a substantially constant cross section perpendicular to the longitudinal extension, the cross section preferably being identical except for recesses and/or punchings in the mounting rail base and/or mounting rail side walls. Often the cross section the support rails, in particular all of the support rails, are essentially the same. The support rails are usually fixed relative to one another by the mechanical coupling, perpendicular to the longitudinal direction.

The mounting body is usually arranged at the open vertical end of the mounting rail, so that the mounting body vertically delimits the receiving space defined by the mounting rail and the receiving space is surrounded by the mounting rail and mounting body perpendicular to the longitudinal direction, defining a cavity. The enclosure of the accommodation space, which is formed by the support rail and mounting body, can be interrupted at least in some longitudinal sections, for example in order to allow access to the accommodation space, for example for the air supply. The receiving space is preferably continuously enclosed over at least 80%, in particular at least 90% of its longitudinal extension, in particular over its longitudinal extension. The mounting body often has a cross section perpendicular to the longitudinal direction, which comprises a mounting body base extending in the transverse direction and mounting body side walls extending vertically away from the mounting body base on the two transverse sides of the mounting base.

Support rail and mounting body are usually made separately from each other. Support rails and/or mounting bodies are particularly preferably each produced from sheet metal by forming. In an operating position of the system in which the system is used as intended, the mounting body is usually held by a retaining spring on mounting rail retaining anchors of the mounting rail. Various options for realizing such a retaining spring are known in the prior art. Usually, the retaining spring is firmly connected to the mounting body and has retaining projections that can be elastically deflected in the transverse direction. The mounting rail retaining anchors are preferably designed as projections.

In particular, to supply the functional elements arranged in the receiving space or cavity described, appropriate wiring running in the support rail or the receiving space can be provided in the generic system. A generic system can also have a current conducting rail, which is mostly made of plastic, in particular by means of an extrusion process, and which is also elongated in the longitudinal direction. The current conducting rail is usually arranged on an inner side of the mounting rail facing the interior and is fixed to the mounting rail, in particular to the mounting rail bottom and/or to at least one of the mounting rail side walls. The current conducting rail extends over a significant proportion of the length of the mounting rail, in particular over at least 80% of the length of the mounting rail. The current conducting rail usually has a plurality of channels which are arranged next to one another along the transverse direction and which are open towards an access side which is accessible from the accommodation space. The channels preferably extend continuously over the entire length of the current-conducting rail. In particular, the transverse direction, the longitudinal direction and the vertical direction run perpendicular to one another. In the operating position of the system, a conductor wire is arranged in at least one of the channels, and the conductor wires are usually connected to an external voltage source at least at one longitudinal end of the conductor rail, via which electrical energy and/or electrical signals can be applied to the conductor wires. For this purpose, a particular is usually at the longitudinal end arranged as an electrical feeder formed electrical connector which is electrically connected to the lead wires. In most cases, an electrical connector is provided at each longitudinal end of the current conducting rail. The electrical connectors can, for example, be in the form of connectors that correspond to one another, for example a first connector as a plug and a second connector as a socket. If at least one connector is provided on at least one longitudinal end of the current conducting rail, current conducting rails that are adjacent in the longitudinal direction can be electrically connected to one another, so that the line wires can form through-wiring.

The current conducting rail with the line wires arranged in its channels is used to supply power to electrical functional elements of the light, which are to be fixed at various longitudinal positions along the mounting rail to implement the light and are electrically conductively connected to at least some of the line wires for the electrical supply. Such functional elements in generic systems can be, for example, light modules, in particular circuit boards with LEDs, control gear, radio modules, sensors such as cameras, or presence detection sensors.

A generic system is particularly preferably used to implement such an elongate lamp in which at least two lamp assemblies are arranged one behind the other in the longitudinal direction. Each of the lamp assemblies includes a mounting rail and a current-carrying rail, which are arranged relative to one another as explained in the assembly state of the system, and the two lamp assemblies are connected to one another by the mounting rails being mechanically connected to one another by the coupling already explained the conductor rails are connected to one another at their ends pointing towards one another by an electrical connector which electrically conductively connects one conductor wire which is arranged in the conductor rail of one of the light assemblies to one conductor wire which is arranged in the conductor rail of the other light assembly. In order to ensure the desired modularity of the system, the mounting rail and conductor rail of a generic system must be designed in such a way that they can form a lighting assembly that has a receiving space (cavity) that can be closed at the longitudinal ends and on the other hand with another lighting assembly can be connected, in which case the two lamp assemblies each form a common receiving space (cavity) which is to be closed at its longitudinal ends-Shen so that a closed interior of a lamp can be realized.

Generic systems are therefore specifically designed to be highly modular in order to enable the realization of different lights, for example for use in warehouses, production halls, supermarkets or open-plan offices. Luminaires realized by means of a generic system can thus comprise, for example, a large number of luminaire assemblies which are arranged one behind the other in the longitudinal direction and are connected to one another as explained. Furthermore, depending on the area of application and the resulting need, a wide variety of electrical functional elements and a wide variety of control options for the electrical functional elements can be provided in such a lamp. Since in generic systems, the mounting rail when using a Stromleitschiene together with this provides the basic structure of each such lamp that means If a generic system is implemented, the mounting rail and current conduction rail must be designed in such a way that they allow these components to be accommodated and supplied depending on the selection of the mounting body used, the contact device used and the functional elements used. As stated above, it is also possible to realize a lamp for the mentioned areas of application without using the said current conducting rail, by using cabling in the receiving space to supply the individual electrical functional elements.

Generic systems for realizing an elongate lamp can have means for influencing a direction-dependent light output of the lamp, for example in the form of a diffuser cover, for setting predetermined light distribution functions of the realized lamp. However, the applications of such generic systems mentioned make it necessary to provide an optimal light distribution function of the luminaire produced with the generic system specifically for the respective application. For example, when applying a generic system in an office environment, the aim is to provide lighting that is as uniform as possible, while in retail, systems for realizing elongated luminaires that provide an asymmetrical light distribution function are appropriate. Generic systems are currently not able to provide this flexibility in providing specified light distribution functions while maintaining the specified modularity of the system. In this respect, the present invention is based on the object of providing a system for realizing an elongated luminaire which allows greater flexibility in the setting of desired light distribution functions Maintaining the fundamentally modular structure of the system.

The present invention solves this problem with a system for realizing an elongate lamp with the features of claim 1. The system according to the invention for realizing an elongate lamp comprises at least one support rail which is elongate in a longitudinal direction and has a cross section perpendicular to the longitudinal direction, with a support rail base and a first and second mounting rail side wall extending vertically away from the mounting rail base, in particular perpendicularly to the longitudinal direction, and at least one mounting body which is elongated in the longitudinal direction and on which a light source and/or another functional element can be arranged, the mounting body having a cross section perpendicular to the longitudinal direction with a Mounting body base and a first and second mounting body side wall extending vertically away from the mounting body base, with the mounting rail and mounting body being fastened to one another in the operating position, to form a first receptacle (receiving space) between the bases of the mounting rail and the mounting body, and the system also has at least one longitudinally elongated covering device having light control functionality, via which light emitted by the light source can be emitted, for providing a predetermined light distribution function of the lamp. The system according to the invention is characterized in that the covering device has an opaque housing that is elongated in the longitudinal direction and has a cross section perpendicular to the longitudinal direction, with a housing base that has at least one recess and a first and second housing wall that extends vertically away from the housing base, with the covering device housing Also referred to below as the cover housing, and the mounting body are attached to one another in the operating position, to form a second receptacle (receiving space), which is arranged between the bases of the mounting body and the cover housing, in which at least one optical element is arranged in the operating position, which on the light input side the base of the mounting body and the light output side of the at least one recess of the cover housing is facing.

By providing a cover device, which in terms of its basic design is constructed in the same way as the support rail and the mounting body, with a respective base section and first and second housing side walls extending away from it in the vertical direction, a further interior space can be defined which is limited by the bottom of the mounting body, in which one or more optical elements can be arranged to set a predetermined light control within the cover and thus to provide a predetermined light distribution function of the lamp. According to the invention, this second receiving space can be equipped with optically differently acting elements, depending on the application, and thus offers a high degree of flexibility in providing desired optical properties of the lamp while maintaining the modular design of the system according to the invention.

It can preferably be provided that the covering housing of the covering devices with different optical effects is essentially the same, in particular identical, so that the different optical properties are provided simply by inserting optical elements adapted to the respective application into the second receiving space provided by the covering housing. Through the inventive design of the system for realization For example, in an elongated luminaire, a symmetrical light distribution function can be set in a plane perpendicular to the longitudinal extent of the luminaire, as is often desired in particular in office environments. By appropriately selecting the at least one optical element that can be inserted into the second receptacle, asymmetrical distribution functions can also be set, for example, in a plane perpendicular to the longitudinal extension of the lamp.

Provision can be made for at least one of the parts of the support rail, mounting body and covering housing to be designed as a sheet metal part, in particular as a roll form, which represents a cost-effective variant. In particular, the support rail and the mounting body can often be designed as a sheet metal part. The same applies to the covering housing, which in particular can also be designed as an injection molded part.

Provision can preferably be made for the cross sections of the at least one mounting rail, the at least one mounting body and the at least one cover housing to be approximately U-shaped, with a respective mounting body side wall being connected to an associated one of the two mounting rail side walls in the operating position for fastening the mounting body to the mounting rail is to define the first recording already described.

In order to provide sufficient flexibility in the design of the optical functionality of the covering device, it has been found to be expedient for the second receptacle to extend vertically by a factor of about 0.4 to 0.8, in particular by a factor of 0.5 to 0.7. times the vertical extent of the first shot. In particular, the setting of the described vertical ratio of the two recordings to a value of about 0.60 or slightly below has proven to be particularly advantageous. The vertical extension of the first receiving space is determined by the distance between the support rail base and the mounting body base and the vertical extent of the second receiving space is determined by the distance between the mounting body base and the housing base of the covering device housing.

In order to optimize the appearance of the luminaire realized with the system according to the invention, it can expediently be provided that in the operating position the cover housing in the area of vertical end sections of its two housing side walls rests light-tight on the mounting body, in particular on the bottom of the mounting body, so that no light is present in the area of connecting sections between the covering device and the mounting body can leave the luminaire and disturb the appearance of the luminaire. The light-tight system described can be formed directly or indirectly, the latter for example by providing a seal against which the respective associated connecting portions of the cover housing and the mounting body abut. In particular, it can be provided that both housing side walls in the region of their vertical end sections each have a contact flange extending in the transverse direction, which rests directly or indirectly on an associated contact surface of the mounting body, in particular the mounting body base, as described above.

To attach the covering device or the covering housing to the mounting body, For example, a screw connection can be provided, in which screw bolts can be provided, which extend, for example, through a passage in the contact flange at the end sections of the side walls and through a passage aligned therewith in the base of the assembly body.

In addition, other fastening configurations can also be provided for fastening the covering device or the covering housing to the mounting body, for example via a latching mechanism in which one, in particular a plurality of, latching elements can be arranged on the mounting body, which, in the operating position, can be used for fastening with latching elements which act in a complementary manner and which are arranged on the covering housing the covering device on the mounting body interact.

Preferably, the cover housing base of the cover housing can have a plurality of longitudinally consecutive recesses which are spaced apart by respective transverse webs of the cover housing base, wherein a respective recess from the row arrangement of recesses can be assigned an optical element from a row arrangement of optical elements.

The optical elements can preferably be constructed essentially identically with regard to their geometric design. The optical elements of a set can preferably be configured identically with regard to their optical properties.

Depending on the embodiment, one or more LED light sources can be assigned to an optical element. Along with this assignment can be provided that a or the plurality of LEDs assigned to the respective optical element and the optical element in the operating position are arranged relative to one another in such a way that the light emitted by these LEDs is essentially completely received by the assigned optical element on a light input side (light input side) and on a light output side for provision of a respective contribution to the design of a specified light distribution function of the luminaire leaves the optical element or emerges from it.

In this case, the series arrangement of the LEDs can be arranged, for example, on a circuit board, in which case the circuit board itself can be arranged on the side of the base of the mounting body that faces the covering device. It can be provided that the at least one LED is arranged within a surface section of the base of the mounting body, which results from a vertical projection of the opening surface of the recess running in a plane of the covering housing base onto the base of the mounting body or the LED circuit board arranged there.

It can expediently be provided that, in the operating position, the at least one optical element is supported on the circuit board of the lighting means.

Depending on the application, the system according to the invention can comprise a plurality of sets of optical elements, it being possible for each set to have a plurality of optical elements of identical construction. This makes it possible to adapt a respective set of optical elements to a respective specific application for designing a predetermined light distribution function of the luminaire. For example, it is possible with a given first set of optical elements in the operating position to provide a symmetrical light distribution function in a plane perpendicular to the elongated luminaire, while with the optical elements of a second set, where the optical elements of the second set can be constructed identically, one in one Plane perpendicular to the longitudinal axis of the lamp to provide asymmetric light distribution function and / or a double asymmetric light distribution.

In principle, an optical element can have one or more optical functional elements such as a lens, reflector, diaphragm device and/or diffraction element, which provide a light-guiding functionality in a specific way.

The combination of a lens connected in series with a diaphragm device can have the advantage that a desired light control can be achieved by refractive and/or total reflection surfaces of the lens body, while the subsequent diaphragm device is used to switch off unwanted light rays in order to design a predetermined light distribution function of the luminaire with the diaphragm device by falling onto wall sections of the screen device and thus being blocked. It can be provided that less than 10%, less than 5%, in particular less than 3% of the light emerging from the lens is blocked by the diaphragm device in order to achieve the desired light distribution function.

It can also be provided that the lens has a holder for holding or fastening the optical element in the second receptacle between the base of the assembly body and the base of the cover housing, as well as an optically effective lens body for directing the light, which improves the handling of the respective optical element, for example when assembling the lamp. much easier. It can be provided that sets of different optical elements have an identical structure in relation to the holder of the lens body, but differ in relation to the provision of different optical properties in relation to the lens body. Depending on the embodiment, the aperture devices of the sets of optical elements that are optically downstream of the respective lens can be constructed identically.

Preferably, an aperture device or a reflector can be designed conically to form an optical element and, in one embodiment, can be placed on the holding frame of a lens. Such a reflector or a screen device preferably has a contact flange on the front side in the light exit area, which in the operating position can be designed to rest against the housing base of the covering device.

In the embodiment described above, it may be provided that a plurality of lenses made integrally and connected in series to each other at their supporting frames are assembled with a plurality of aperture means made integrally and connected to each other in series in operative position to form the plurality of optical elements arranged in a row in the form of an optical cluster element, each of the lenses being associated with a respective diaphragm device.

These optical cluster elements can, for example, be adapted to the number of optical elements to be arranged in a given covering device. For example, the number of optical elements within such an optical cluster element can be adjusted such that several such optical cluster elements, in particular two, are accommodated in the second receptacle, so that a respective optical element is assigned to all recesses in the cover housing base.

Such a cluster element can expediently be fastened to the mounting body, for example an optical cluster element can have at least two fastening elements, in particular locking hooks, which extend through the mounting body base in the operating position and which interact with associated fastening elements on the mounting body base to connect the cluster element to the mounting body base. For this purpose, for example, the fastening element can be guided like a latching hook through an associated passage through the base of the mounting body and latch on the opposite side of the base of the mounting body.

As shown, the optical elements can be designed to set a predetermined light distribution function of the lamp. In particular, the optical elements can be designed to provide a double asymmetrical light distribution function in a plane perpendicular to the longitudinal extension of the lamp. It has been found that such a light distribution function of the luminaire is already achieved by providing a sandwich structure in series arranged optical elements can be achieved, wherein the respective optical element has a single lens as the optical functional element, wherein a second optical functional element to complete the sandwich structure in the form of a pot-like aperture device with a conical surface assigned to the first optical functional element can be connected downstream.

figure 1 shows an elongate luminaire designed with an embodiment of the system according to the invention. The lamp 1 first has a mounting rail 2 for fastening the lamp to a component, not shown, such as a ceiling, the mounting rail 2 being elongated in the longitudinal direction X and having an approximately U-shaped cross section perpendicular to the longitudinal direction. The mounting rail 2 comprises a mounting rail bottom 20 which extends essentially in the illustrated xz plane and from which a first and a second mounting rail side wall 21a, b extend vertically, ie in the y-direction. The support rail 2 is connected to a so-called mounting body 3 in the area of the free end sections of the support rail side walls 21a, b. In this case, the mounting body 3 is elongated in the longitudinal direction X, in the described embodiment of the lamp with an identical length to the mounting rail. In a cross section perpendicular to the longitudinal direction X, the mounting body has a mounting body base and a first and a second first and second mounting body side wall 31a, b extending away from the mounting body base 30 in the vertical direction y. The free ends of the mounting rail side walls 21a, b can be seen to lie against the free ends of the mounting body side walls 31a, b and are detachably connected to one another there. How out figure 1 visible, the support rail 2 and the mounting body 3 form a receiving space 80, in which, for example, functional elements of the lamp for operating the light source of the lamp can be arranged.

In the described embodiment of the system according to the invention, the luminaire 1 also has a covering device 4 which, in a manner to be described, provides a light directing functionality via which light emitted by the illuminant can be emitted to provide a predetermined light distribution function. For this purpose, the covering device has a plurality of optical elements 5 arranged in a row, which in the enlarged view of FIG figure 2 are recognizable.

figure 3 shows the mutual operating position of support rail 2, mounting body 3 and cover housing 40 in an oblique front view. Cover housing 40 is U-shaped in a similar way to support rail 2 and mounting body 3 and has a cross section perpendicular to the longitudinal direction X (see figure 1 ) a housing base 60 and a first and second housing side wall (61a, b) extending vertically away from the housing base 60. The housing base 60 of the covering housing 6 has a plurality of recesses 62a, b . In the area of the free ends of the side walls 61a, b there is provided a fastening flange 65a, b which is aligned with the base 30 of the assembly body and with which the covering housing 6 rests on the base 30 of the assembly body. In the embodiment described, the cover housing 6 is bolted to the mounting body 30 at the flanges 65a,b, bolts (not shown) extending through respective passages on the flanges and aligned passages on the bottom 30 of the mounting body.

figure 4 shows the housing 6 on its own in a perspective oblique view. The contact flanges 65a, b have respective widenings with bushings at their longitudinal ends for receiving screw bolts for fastening the covering housing 6 to the bottom 30 of the mounting body 3.

figure 5 shows a partial view of the luminaire 1 , wherein a number of optical elements 5 are taken out of the second accommodation space 90 for visualizing a row of LEDs. In the embodiment described, the row of LEDs is formed by a plurality of LED groups of four LEDs each, each group of four being associated with an optical element 5, see FIG figure 2 . The light emitted by one of these LED groups enters the optical element 5 on the input side, is deflected in a defined manner and exits the optical element via an associated recess 62a, b on the housing base 60 of the cover housing 6.

In one embodiment it can be provided that each optical element 5 is to be placed in the second receiving space 90 separately from the other optical elements.

However, particularly expediently, it can be provided that several of the optical elements are integrally manufactured in the row arrangement corresponding to the operating position, which considerably simplifies the assembly of the lamp according to the invention. In the embodiment described, the optical element 5 comprises two optical functional elements, namely a lens 50 and a pot-like diaphragm device 55, see FIG Figures 6, 7 . The lens 50 is made as an injection molded part and comprises a frame 51 and a lens body 52 made integral with the frame, which for actual light control is responsible. In order to simplify the assembly of a lamp designed according to the invention, in the embodiment described several lenses 50, here five, are matched in series to the row of LEDs on circuit board 6a, see FIG figure 5 , arranged in an adapted manner and adjacent lenses 50 are connected to one another via webs that are not visible in the figure.

The aperture device 55 is designed with an inwardly tapering aperture surface 56 and has a contact flange 58 on the light exit side. In the same manner as the lenses 50, in the embodiment described, an equal number of aperture devices 55 are integral in an attached to the lens array of FIG figure 6 adjusted so that the aperture arrangement of the figure 7 on the lens arrangement of the figure 6 can be placed, the projections 57 on the outside of the panel devices 55 engaging in associated recesses 53 of the respective frame 51 .

Figures 8a, b show the optical cluster element assembled as described in a perspective top view ( Figure 8a ) and in a perspective bottom view (Figure 8b). Depending on the embodiment, the respective lens can be connected to the respective diaphragm device by means of mutual latching, so that the optical cluster element 8 can be handled as a one-piece part when realizing a lamp according to the invention.

In the described embodiment, the entrance surfaces or coupling surfaces 54 of the respective lens are formed in a recess and encompass the reference to FIG figure 5 described LED groups 7 sections. Depending on the embodiment, it can also be provided that the LEDs dip into assigned recesses of the respectively assigned lens 50 . The optical cluster element 8 can be seen to have latching arms 80 and centering pins 81 which, in the operating position, extend through associated openings in the base of the mounting body for centering or latching the optical cluster element with the mounting body on its base 30.

The series arrangement of several optical cluster elements 8 or a series arrangement of a large number of in figure 8 specified individual optical elements 55, leads to a substantially symmetrical light distribution in a plane perpendicular to the longitudinal axis of the lamp. A corresponding diagram is in figure 9 specified. In contrast to the lens series of the figure 6 , the lenses of the lens array of the Figure 10a no essentially rotationally symmetrical deflection behavior, but due to a specific design of the input or coupling side of the lens and the light coupling-out side of the lens, a strongly asymmetrical behavior again in a plane perpendicular to the longitudinal axis of the covering device 4 equipped with these lenses. Figure 10b shows this asymmetrical light control, which can be used, for example, to illuminate a given area of a wall-mounted writing board.

In addition, the system according to the invention can also have lenses or a row of lenses for the design of a covering device which exhibits a doubly asymmetrical emission behavior of the luminaire. It has been found that in particular a corresponding design of the in-coupling surface of the lens leads to the desired double-asymmetrical distribution curve. Figure 11a shows such an optical lens row with a view of the respective coupling surface.

It should be noted that the respective frame of the lens for the different lenses or lens rows described, which have different light directing properties, can be constructed identically, so that a lamp according to the invention can be changed from a first light distribution curve to providing another, predetermined light distribution curve by simply exchanging the lenses, which illustrates the modular character of the system according to the invention for designing an elongated lamp.

In this embodiment, the coupling surface 100 of the lens has a longitudinally symmetrical shape in the form of three longitudinally oriented and parallel ridges such that the cross section perpendicular to the longitudinal extent of the coupling surface 100 remains essentially constant. Figure 11b shows the bottom view of this lens in a perspective view from which it can be seen that the coupling surface 100 is designed as a cover surface of a recess of the lens body, into which the LED grouping (not shown) can dip at least in sections.

Figure 11c shows a cross section through a lamp with a row of lenses 10 of Figure 11a is equipped, with exemplary beam paths S are given. The described double asymmetrical light distribution perpendicular to the longitudinal direction of the lamp can already be seen from this representation, a corresponding representation shows Figure 11d .
