Description

The invention relates to a lighting system with an elongated mounting rail, which can be fastened by means of a fastening means to a wall or ceiling, at least one equipment carrier which comprises a light source and electrical components for operating the lamp, and an optics for steering and / or scattering of the Illuminant radiated light.

Such light band systems are used for lighting mostly an interior, in particular from the ceiling of long rooms, such. Workshops, workshops and the like. As light bulbs are often used fluorescent tubes. The electrical components include, for example, ballasts, sockets, wiring and the like. for the operation of the bulbs. The associated optics are often in the form of concave and possibly white lacquered sheet metal profiles as reflectors and the like. designed. Furthermore, translucent plastic lamp covers are also known.

Known trunking systems are mostly attached hanging from the ceiling, with rods or wire ropes are connected as fastening means with the ceiling and the mounting rail. On the support rail of the equipment carrier are formed connected to the light source and the electrical components and the optics. Known support rails may have different lengths depending on the application and extend for example from 1.50 m to 3.00 m to 4.50 m. Several mounting rails can be used for a wide variety of lighting units to be ordered. Because of the elongated shape of the mounting rails and the resulting visual impression during operation of the lamp arrangements of mounting rails and lamps and the other components described above, which are assembled into elongated, suspended from a ceiling structures, referred to as "ribbon systems".

In practice, such a lighting system essentially comprises three components, firstly the mounting rail, secondly the lighting means, including the electrical components necessary for operation, and thirdly the optics. The assembly takes place in known light strip systems in several stages. For example, for a lighting of the ceiling, first the mounting rail attached, in which then the components and the light source are used and around which ultimately the optics is mounted, which regularly requires several people.

The variability of known light band systems is limited by or on the length of the mounting rails. These are difficult to transport because of their long length. Furthermore, the installation of existing lighting system is complex, because first the support rail and then the two other components must be mounted one after the other. In particular, the long support rails of 4.50 m are of course very difficult to transport and assemble. DE 20 2010 006 329 U discloses a lighting system.

Based on this prior art, the invention is based on the object to at least partially avoid these disadvantages and to provide an improved lighting system, which has an increased variability, is easy to transport and in particular is easy to install.

The object of the invention is achieved by a lighting system according to claim 1.

By means of this embodiment according to the invention, the installer can mount the mounting rails located on the light band element as a complete system under the ceiling, and light band elements can be added as needed to form a light band system. The integrated in the light band elements support rail is therefore mounted automatically. When removing a device carrier, the mounting rail then virtually remains as a continuous "supply unit", which receives at least the through-wiring. Thus, an otherwise unwieldy, long support profile is resolved into an easily manageable size and integrated into the lighting system, which is easy to install. Furthermore, the Lichtbandtragschiene formed from several juxtaposed mounting rails offers the ability to position the equipment carrier with the lamps provided thereon arbitrarily along this Lichtbandtrageschiene, move and equipped with demand-adapted equipment carriers for the realization of zonal lighting with special light distribution curves. Also, such a simple adaptation to new visual tasks by replacing the gear tray is possible.

The support rail preferably comprises at least one substantially U-shaped support profile in order to accommodate or implement at least the through-wiring; but also other electrical components can be arranged in the mounting rail. In the preferred embodiment, the support rail is formed as an extruded or canted profile. Preferably, the support rail is made of steel, but may also be made of other metals, e.g. Aluminum, or plastic, e.g. PE, POM, PET or PC and be made of fiber-reinforced plastic.

In a preferred development of the invention may additionally or integrally comprise a cable channel on one side of the support rail, in which further lines, cables and components are arranged. For retrofitting on demand, this cable channel is preferably attachable to the support rail, e.g. by means of a latching connection. This offers the advantage that the support rail, which generally comprises seven lines, can be supplemented by further lines as required. At the same time it is not necessary to equip the standard support profile always with the additional lines. Thus, the system is variably adaptable to the installation situation and can be realized more easily and compactly. In this additional channel or lines for emergency or single battery circuits can be provided.

The fastening means on the mounting rail preferably comprise cables and rods, in particular of steel.

The length of a light band member (module length) preferably has lengths optimized to realize maximum packing density when stacked on a Euro pallet; this is currently two standard lengths, namely a length of 0.50 m and a length of about 1 m. The mounting rail the light-band element according to the invention is thus significantly shorter than known support rails, so that the light band system according to the invention is basically more efficient, ie easier and less expensive to pack and transport than known systems. The compact and modular design of the light strip element allows a one-man installation of the lighting system and thus simplifies installation. In all embodiments of the invention described in more detail below, a tool-free assembly is possible. When disassembling sometimes tools may be slightly required, for example, to release snap-in connections. Preferably, however, a tool-free disassembly is feasible.

Several light band elements can thus be connected to one another by means of the connecting elements to form a light band system, preferably on front sides of the light band elements adjacent to the installation position in order to realize an end-side connection of the light band elements and thus the visual impression of a continuous, uninterrupted light band system. The connecting elements are therefore preferably arranged on the end face or in the vicinity of the end face of the light band element, particularly preferably in the mounting rail. The end faces of the mounting rail may have a miter in the transverse direction to provide a larger contact surface in the connection.

It is essential that each light band element is designed to realize an electrical through-wiring, so that a light band element can be supplied with current (voltage) from the adjacent light band element in each case. The feed into the through-wiring is preferably at the end. For this purpose, a corresponding head piece may be provided on one of the end faces of the light band element. At the opposite end side of the light band element or light band system may be provided an end piece or an end cap for optical veneering. The feed can also be made centrally, then end caps are preferably attached to the two free end faces of the light band system, which complete the trunking system. The head or end pieces made of injection-molded plastic parts, for example, made of PE, PC or PET.

In order to realize the electrical through-wiring by means of the connecting elements, these also comprise electrical connecting elements for realizing the connection at the interface. For example, at least two complementary plug-in parts that can be detachably connected in the installed position can be provided, which are respectively arranged on the front sides of the light band element abutting one another in the installation position, preferably concealed. In the preferred embodiment, the connector parts of two adjoining light band elements on a male and a female connector side, which are preferably siebenpolig. In this way, the through-wiring can be realized in that the complementary plug parts of two adjacent in the installation position light band elements are pushed into each other in the installed position.

Since the through-wiring is permanently live, the plug parts are preferably designed so that those plug elements of the current-carrying plug-in part, can be covered to prevent accidental intervention by installer. This is preferably achieved in that the current-carrying connector elements sit in corresponding recesses of the connector parts. A connection of the connector parts takes place only by the movement or actuation of a slide, which is spaced from the current-carrying plug element. This slider is preferably formed in the vicinity of the end face of the support rail. After aligning Alignment of the two connector elements to each other, this slide is then so displaceable in the installed position that this connects the aligned connector elements galvanically with each other or coupled.

In order to realize a coupling of the connected light band elements and to avoid a mechanical loading of the electrical connection means, it is also expedient that the light band elements comprise the releasable mechanical connection means. These may be formed non-positively and / or positively.

As a non-positive mechanical connection means, for example, a connection profile may be provided, which is designed as a clamping element which engages around the joint of two light band elements and bridges the geometry of the mounting rail on the outside. This clamping element can be made of metal, for example steel or aluminum, or of plastic, for example PE, and is preferably produced by extrusion. This U-shaped connection profile is preferably mounted displaceably on the support rail of a first light band element and is partially slidable for connecting a second light band element to the support rail of the same. For example, at least one guide rail can be formed on the support rail in order to guide the connection profile to another support rail of a light band element to be connected when it is slid on, the connection profile also representing the geometry of the support rail with guide rail. The cross section of the guide rail preferably has a polygonal and in particular square cross section. Other cross-sectional geometries with arcuate edges can also be provided, for example semicircular cross-sections.

In a positive connection preferably the end faces of the light band elements are formed in pairs complementary to each other, wherein the end faces have in the installed position interlocking geometries. Particularly preferred include these link or dovetail guides.

Preferably, the complementarily formed front ends of the light band elements are provided on the complementary in the mounting position joining surfaces of the complementary formed electrical connection means, in particular the connector parts.

Alternatively, a slotted guide can be formed mirror-symmetrically in both adjoining end faces of the light band elements or the mounting rails. This slotted guide is preferably dovetailed. By means of insert elements, which can be used in the slotted guide, for example, the front ends of two light band element or mounting rails can be interconnected.

Furthermore, the mechanical connecting elements can comprise latching means, so that the mechanical connecting elements of a first light band element can be locked with the support rail of a second adjacent light strip element. The locking means may comprise, for example, retaining clips and snap closures. The connecting means may also include pins or guides as well as magnets, hook and loop fasteners and screw caps. Furthermore, laminations for lamination of plastic, e.g. PE, PET or PC be formed.

To avoid mechanical stress on the electrical connection elements, the electrical and mechanical connection elements are preferably decoupled from each other. But the connecting elements can also be designed so that in the realization of the mechanical connection and the electrical connection is realized, for example by arranging the electrical connection elements (eg the complementary plug halves) in the joining surfaces of each other in the installation position behind undercut or overlapping areas.

The mounting rail may comprise the lighting means for designing a light strip, in particular in a ceiling lighting on a lower side facing away from the ceiling side of the support rail. In this case, then preferably the optics on the support rail or the light band element is provided. The support rail can thus be formed integrally with the light bar.

The light band element additionally comprises a light source carrier for receiving the light source, on which the optics is provided. According to the invention, this illuminant carrier and the optics are modularly detachably fastened to the mounting rail in such a way that the illuminant carrier is exchangeable in the installed position without dismantling the lighting system. The optics are therefore preferably releasably fastened to the illuminant carrier, so that a simple replacement of the optics is possible; Alternatively, the optics is integrated into the illuminant carrier. In this case, illuminant carriers and optics are designed as an integral component which can be connected to the carrier rail.

To avoid heat development by the light source of the light source carrier is preferably formed as a heat sink, for example, with a substantially or partially U-shaped cross-section, which comprises cooling leg, which surround the mounting rail in the installed position at least partially. Preferably, the illuminant carrier is a formed extruded aluminum profile to realize a particularly good heat dissipation. The illuminant carrier may also be formed of copper and other heat-conducting materials.

The illuminant carrier may be designed to be displaceable with respect to a mounting rail and with respect to a plurality of interconnected mounting rails. In a continuous-row lighting system consisting of a plurality of connected light-band elements, it is then possible to displace the illuminant carriers, including the light-emitting means, along the connected carrier rails. As a result, a change in the light intensity or the light distribution curve and thus an adaptation to changing lighting tasks can be realized. The vacant spaces on the support module can be covered by cover.

The light source carrier has the particular advantage that the light source and the optics can be solved without tools from the support profile even after the initial installation in order to exchange these for other light sources or to adjust them as needed. In this way, the light band system according to the invention is particularly variable. In particular, in the case of a ceiling installation, the illuminant carrier can preferably be detached from the mounting rail exclusively by carrying out a vertical movement. For example, may be formed on the support rail retaining clip which lock in the installed position in openings of the illuminant carrier. Furthermore, further locking connections or the like. be provided so that the lamp carrier and the mounting rail can be locked together in the installed position. For this purpose, for example, along the longitudinal axis of the support rail extending longitudinal grooves may be formed, in which the illuminant carrier can be latched. In one embodiment of the light band element without illuminant carrier, the connections of the mechanical and / or electrical connection elements may be arranged in these grooves in the vicinity of the front ends of the support rails. Two light band elements can then also be connected at their end faces by virtue of the fact that a connecting piece can be inserted into the groove and has complementary connections to the mechanical and / or electrical connecting elements. If connections for electrical connection elements are arranged in the groove, the connection piece can, for example, have and supply its own additional lighting means, since it is then connected to the through-wiring in the installation position. The connector preferably comprises an insulating plastic sheath, for example made of PC or PE. Particularly preferred only mechanical connection means are arranged in the groove. The electrical connection means are then arranged on the front sides of the mounting rail. These end faces are preferably flat or perpendicular to the longitudinal direction of the mounting rails and aligned in mounting position with each other.

Furthermore, separate grooves for connecting pieces and for light medium carrier can be formed side by side on the mounting rail.

The illuminant carrier and the mounting rail can have plug connectors, so that the illuminant carriers and the mounting rail can be detachably connected to one another for electrical supply to the illuminants. This has the advantage that the entire lighting system from several connected light strip elements is still functional, even if a bulb should fail or is replaced, since the exchange then only the connectors are to be solved and the through wiring is not interrupted thereby. The connector is preferably designed as a seven-pin standard connector.

The lighting means may comprise both conventional light sources, in particular fluorescent lamps and the like, as well as novel light sources, such as LEDs and OLEDs.

The optics or optical disc is preferably made of a translucent plastic body, for example of PET, PC or PMMA, which covers the bulbs, the light of the punk LED light sources bundles produces a possible diffused light. In the preferred embodiment, each optical disc for light bundling on the top of the individual LEDs in the installed position associated with lenses that merge into one another (blended) and are particularly preferably concave.

The invention further proposes a continuous row lighting system with a phase selection device for fast and ergonomic switching of the electrical phase selection for each light band element to the phase of a three-phase alternating voltage to be used and the mechanical separation of each light band element from the support profile for luminaires, in particular for a light band element described above. However, the phase selection device is not limited only to use in the above-described light band elements. For the choice of phase, ie the choice of the corresponding phase of a three-phase alternating current (three-phase current) for the operation of a specific lighting system in known systems, the lights must be completely disassembled, then prefer a phase selection by means of contact displacement. This is expensive and time consuming. The invention proposes here a device which allows a simple and fast phase selection.

The proposed phase selection device is constructed in principle of two parts and comprises an accessible on one side of the light band element locking device, which is preferably designed as a locking drawer. By operating this locking device arranged on the diametrically opposite side of the light band element phase selection drawer is pushed out of the light band element and thus accessible to the user. When the phase-selection drawer is extended, a microfuse can be moved between the phase-shift drawer, which is arranged linearly next to one another in the phase selection drawer, in order to implement the rapid and ergonomic switching of the electrical phases. The fine fuse is arranged on a longitudinally displaceable in the phase selection drawer carrier, which is operated by a slide by a plumber without tools.

The light band system is intended to provide an elongated, highly efficient luminaire which preferably uses a plurality of small light sources (in particular LEDs on LED printed circuit boards) as the luminous means. The linear juxtaposition of the individual light band elements creates a homogeneous and coherent light band.
Current trunking systems have a dark spot in the area of the transition to the next luminaire module due to illuminant detection elements or luminaire housings.

Another, not claimed, aspect therefore relates to a solution for avoiding these unwanted interruptions in the luminous area, in particular at the transitions between the individual luminaire modules or light strip elements. Furthermore, the luminaire should comply with defibrillation specifications according to DIN-EN 12464 and thus achieve the necessary UGR values (unified glare ratio)

In the preferred embodiment, the LEDs on the circuit board are arranged in a single row, and the LED board is also mounted on a cooling profile formed as an aluminum profile. The cooling profile is designed as a U-profile or a channel, being arranged on the LED board on the horizontally oriented in installation position web; this flat base web has at its two sides transversely to the plane of the base web and parallel to each other extending side webs. For glare limitation, a correspondingly shaped panel can be attached to these guide webs, ie directly in front of the board, which is preferably carried out by inserting the panel into guide grooves on the mutually facing inner sides of the side webs of the cooling profile. Depending on the choice of material, the panel can act as a pure light-absorbing panel (black) or as a blend of panel and diffuse or specular reflection (white surface or reflective surface). In addition to the aperture, a transparent optic can be fixed to the cooling profile; wherein the diaphragm and the optics can also be designed as an integral component.

Preferably, the optic is formed as an injection molded part. Depending on the desired light distribution, however, other manufacturing methods are possible. Due to large differences in wall thickness occurs in the injection molding process, a deformation of the optics during cooling after removal from the injection mold on. This deformation of the optics is reversed by the attachment to the cooling profile, in particular the insertion into the cooling profile, so that the entire look is flat. The one-sided positioning of the optics in the longitudinal direction preferably takes place via a latching nose, which is introduced in the optics guide profile.

In the preferred embodiment, two optical disks are used for each light band element, which are pushed towards one another from the opposite, open ends in the cooling profile to form a closed and consistent look. In the installed position, these optical discs are thus secured against falling out of the cooling profile.

To avoid dark spots between the optics or optical disks of the front side adjacent light band elements lamination elements can be used, which support the impression of a continuous, homogeneous, so uninterrupted luminous light band. For this purpose, the lamination element is preferably designed or arranged so as not to be visible to an observer, and furthermore preferably has light-conducting properties so that it enables illumination in the region of the optical disc which covers or covers the light-sealing element from the inside.

The laminating element is preferably designed to be resilient and thus prevents use between two impact-side adjacent optical disks, that the two optical disks can move further in the direction of the center or the outer edge of the light band element, so it holds the optical disks bridging the separation or joint top side and therefore not visible to the viewer against each other in installation position under bias. Particularly preferred without a further abutment for abutment only against the impact side adjacent optical disc. In this way, the light band element can also meet the protection class IP40 and further ensured by this structure that the optical discs can move in thermal expansion in the longitudinal direction within the appropriate tolerances, without causing deformation, mechanical stresses or crackling noises occur.

The resilient laminating element may comprise, for example, a substantially rigid and plate-shaped longitudinal web for defining a longitudinal direction, which is preferably paired and transverse to the longitudinal direction projecting, preferably integrally formed struts comprises. In the installation position, the longitudinal web extends with its longitudinal direction transversely to the longitudinal direction of the light band and thus covers from the inside - the top - the joint between two adjacent optical discs. The preferably in pairs projecting from both sides of the plastic web struts lie on both sides under bias against the edges of the adjacent optical discs. To avoid dark spots, the laminating element is preferably made wholly or partly of photoconductive plastic.
Preferably, the light-sealing element are formed as end caps for the optics, which are detachably connectable, eg snap-on.
Thus, a light source carrier with a continuous, in the longitudinal direction of the support rail extending row of LEDs in case of need simply be exchanged for a light source carrier with two adjacent rows of LEDs.

The unclaimed optical concept has several advantages: On the one hand, the optical disks are pressed into the nominal position by being inserted into the cooling profile over the entire length. By inserting the optical disks also creates the ability to fix the optics in the middle, so that for the optics with temperature fluctuations only an extension in the direction of the center of the light band is possible. Through this quasi "floating storage" of the optical disks in the cooling profile mechanical stresses or clicks are effectively avoided. Different LED boards can be fixed to the cooling profile as needed, if the optics are in a linear (extrusion-like) version. In this case, only the position transverse to the longitudinal direction of Light band element for the light distribution significantly, the LED distance in the longitudinal direction but has no significant effect on the light distribution. As a result, the number of LEDs can be easily varied without changing the optical system.

The subject of the disclosure is also - regardless of the light band element of the other disclosure objects - a novel reflector aperture, which is arranged in the installed position between the light source (preferably LED strip) and the optical discs. This reflector panel, also referred to as the "UGR panel" (UGR = Unified Glare Ratio), is used to achieve the glare reduction required in particular in office space. In the longitudinal direction of the light band elements, the UGR aperture ensures that the light is blocked at an angle of less than 25 degrees to the horizontal, with the aperture mainly reflecting the light downwards. This is achieved by a plurality of, in installation position transversely to the longitudinal direction of the light band element or the lamp extending transverse webs, which are arranged in the installed position next to the LEDs of an LED - bar and reflective surfaces whose inclination angle to an - imaginary- vertical axis is slightly larger than half of a - imaginary - horizontal axis included inclusion angle in which the optical disc is not to leak light. Preferably, the angle of inclination of these reflection surfaces is slightly more than 12.5 °. In the transverse direction of the light band elements, the diaphragm essentially serves as a reflector and collects the light which would not escape from the luminaire housing without a UGR diaphragm.

This reflector aperture thus allows effective glare in the longitudinal direction, compensates for light losses by using the laterally emitted light, which could not escape from the interior of the light band without aperture. Furthermore, the reflector panel conceals electronic and mechanical components, such as screw heads. The glare is also realized when LEDs are partially behind the aperture, which makes the use of boards with different LEDs or LED positions is particularly easy. Although the reflector aperture is optimized for a particular LED position, the LEDs may still be at a different distance. At different LED intervals, some of the LEDs behind the bezel may be obscured. Nevertheless, the glare reduction will remain comparable for a comparable luminaire luminous flux. This is the case because almost the entire area between the panels is filled by the LEDs. Using a different LED spacing with the same aperture will reduce luminaire efficiency. The glare-free property remains intact.

To simplify the assembly of the light strip elements, the disclosure also proposes - again separately from the other objects described above (phase selection device, reflector panel, Kaschierungselement) and not limited to a lighting system - a special mounting screw before, which is operated without tools. This mounting screw consists essentially of two components. In the delivery state, the two components, namely the actual screw, which is preferably designed as Allen screw made of metal, and an actuating or rotating element (preferably made of plastic), which is captive in the delivery state connected to the screw to form the mounting screw. This connection can be done by injection molding of the screw, for example by injection molding. The encapsulation takes place in such a way that the wing can transmit a large torque to the screw when rotating about the screw longitudinal axis, for example by profiling on the inner surface of a screw surrounding the screw in the mounting position ring of the rotary member from which two pivot arms extend. By little effort in the longitudinal axis direction of the screw, the rotating element can be removed from the screw, since the wall thickness of the plastic part in the corresponding area has a thinner wall thickness. The wing is shaped so that it is easily rotatable and it preferably has an undercut, can engage behind the finger to exert a sufficiently high force in the longitudinal axis of the screw. At a Alternative embodiment, the rotary member is designed as a form-fitting insertable rotary handle in the Allen screw. The preferred embodiment provides that the remote from the screw rotary element can later be placed back on the screw and used to operate the screw; an alternative embodiment provides that the rotating element after removal can not be re-attached to the screw. A particular further advantage of the proposed solution is the simple and unmixed separation of the materials for possible recycling processes.

Those skilled in the art will appreciate that in particular the described reflector panel, the lamination and the phase selection device and the mounting screw detached from the light band element or the lighting system in other lights can be used to solve the problems outlined and achieve the effects described, so that Protection is not limited to use in a light band element, but is claimed independently.

The clutch 13 may further comprise not shown locking means over which it is captively locked with one half in a first support rail 3 of a first light band element 2 and the other half with the support rail 3 of a second light band element 2 in the installed position.

The second embodiment differs from the first one in that guide rails 3a are integrally formed on the support rail 3 in order to guide the connection profile 13b. Furthermore, no separate illuminant carrier is provided. The end faces 3b of the support rail 3 have a miter in the transverse direction in order to provide a larger contact surface in the connection.

The in the Figures 10 - 12 illustrated third embodiment differs from the second embodiment essentially in that the support rail 3 has two extending in the longitudinal direction of the support rail 3 grooves 14. The terminals of the coupling 13 and the electrical connection means 12 are arranged in this groove 14 in the vicinity of the end faces 3b of the support rails 3. The connections of the coupling 13 are formed as receptacles 13g with a circular cross-section. The terminals of the electrical connection means 12 are designed as 9-pin connector parts 19. A connector 15 with a Kunststoffummantlung of PE, which is insertable into the groove 14, comprises on the one hand complementary connections to the plug part 19; On the other hand, 15 pins 13c are provided on the connecting part, which are inserted into the receptacles 13g. Two light band elements 2 are connectable to the end faces, that the connecting piece 15 in the groove 14 in the region of the connector parts 19, the receptacles 13 g and the joints of two light band elements 2 is used. At the in FIG. 10 illustrated variant of the connecting piece 15a has this two own additional lighting means 15b. Finally, no separate device or illuminant carrier is provided in the third embodiment.

The in the FIGS. 13 and 14 The fourth embodiment differs from the second embodiment in that the end faces 3b of the light band elements 2 are designed to be complementary in pairs, in the form of mutually overlapping sections in the installed position, to form a closed rectangle and thereby provide additional clutches 13 in one piece on the mounting rail 3a. The connection is realized here by a complementary dovetail guide 16. In the installed position, complementary plug-in parts 19 of the electrical connection means are arranged on adjacent joining surfaces of the complementary-shaped end faces 3b of the support rails 3, which engage in the installation position and thus realize the electrical connection.

The in the FIGS. 15 and 16 illustrated fifth embodiment differs from the fourth embodiment in that the end faces 3 b of the light band elements 2 are flat or perpendicular to the longitudinal direction of the respective support rails 3 and the slide guides 17 in both adjacent end faces 3 b of the light band elements 2 and the support rails 3 formed symmetrically are. The slotted guide 17 is dovetailed.

The end faces 3b of two adjoining or abutting light band elements 2 or mounting rails 3 are connected to each other can be connected by means of separate insert elements 18 which can be inserted into the link guide 17. On the front side 3b, a pin 13c is formed, which engages in the installed position in a not shown, complementary opening on the end face 3b of an adjacent light band element 2. In addition, no further mechanical connection means or guide rails 3a are provided on the support rail 3. The electrical connection elements 12 are movable by means of a slide 21 and can be connected or coupled to one another. On the operation of the slider 21 will be discussed in more detail in the following embodiment.

The in the FIGS. 17 and 18 illustrated, sixth embodiment differs from the third embodiment in that only mechanical connection means are arranged in the groove 14, which are formed as a snap closure 13d and each having a diaphragm 13e for lamination. On the front side 3b two guides 13f are arranged, which extend in the longitudinal direction of the support rail 3 and perpendicular to the end face 3b. The complementary plug parts 19 of the electrical connection elements 12 are provided on the end faces 3b of the support rail 3.

To avoid electric shocks of the fitter, the current-carrying connector elements 19a sit in corresponding recesses 20 of the connector parts 19. A connection of the connector parts takes place only by the operation of a slider 21 which is spaced from the current-carrying connector elements 19a. This slide 21 is formed in the vicinity of the end faces 3a on the mounting rail 3 and is then aligned after alignment of the two complementary connector parts 19 in installation position so that this also connects the aligned connector elements 19a galvanically with each other.

The FIG. 19 shows an exploded view of a light band element 2 comprising the support rail 3, the head side half in the support rail 3 inserted coupling 13 acting as a heat sink illuminant carrier 7, designed as an LED strip 4a bulbs, an optic 6, which by means of end caps 22, 24 formed Light sealing elements is completed, and the necessary control gear, including a phase selection switch.

This phase selection switch consists of a drawer-like locking device 28 and a phase-selection drawer 30, which is snapped onto a support profile 32 formed as a sheet-metal profile. The phase-selection switch is in installation position so in the- H-shaped and used as a light source 7, that the front side of the locking device 28 via an actuating opening 34 in a first longitudinal side of the cooling leg 9 of the illuminant carrier 7 is accessible. A pressure on this front-side actuating plate of the locking device 28 causes a spring-biased pushing out of the phase selection drawer 30 from an actuating opening on the opposite cooling leg 9 of the lamp carrier 7, whereby a slider with a fine-wire fuse for carrying out the phase selection is adjustable in the longitudinal direction. To complete the phase selection, the phase selection drawer 30 is inserted against spring tension again in the operating opening of the cooling leg 9.

The FIG. 20 showed a perspective view of two via a coupling 13 firmly interconnected mounting rails. 3

The FIG. 21 shows a longitudinal section through these two support rails 3, and the FIG. 22 shows an enlarged section of the impact-side connection region between the two support rails 3 with this connection region bridging coupling 13 according to the section AA FIG. 21 , It can clearly be seen that the coupling 13, the perspective again in the FIG. 23 is shown enlarged, is inserted in each half in each support rail 3.

The coupling 13 is formed as a folded sheet metal profile. In the installed position, upper-side connecting legs 36, which define a horizontal plane and from which two vertical legs 38 and 40 extend at right angles downwards. In the longitudinal direction of extension, an elongate spring tongue 41 is formed in the connecting leg 36. The coupling 13 can be inserted into the support rails 3 at half the total length with little play. The captive fixation within the support rails 3 takes place only by tightening the mounting screws designed as wing bolts 42 of clutch springs 44, which are each arranged in the region of the ends of the support rail 3. Turning down the thumbscrews 42 presses on the resilient ends of the spring tab 41 of the clutch 13, so that the spring tab 41 is arched upwards and thus realized a frictional engagement with the inner sides of the support rail 3. Hereby, a quasi-rigid connection between the support rails is realized, so that a backlash-free installation without bending over distances of several light band elements (= luminaire module lengths) is possible. The front end of the coupling 13 has a bevel in order to simplify the passing past the clutch springs 44 for insertion into the mounting rail 3 of the adjacent light band element 2 which is adjacent in the installation position.

FIG. 29 shows an exploded view of another embodiment of a light band member 44 without the support rail. The illuminant carrier 46 is again formed as an aluminum profile, which is H-shaped in cross section is. The two in mounting position vertically extending cooling leg 48, which can accommodate the mounting rail, not shown in the installation position and thus enclose, are connected by a arranged in the lower fifth connecting web 50 to form a longitudinally rigid illuminant carrier 46 integrally with each other. The area under this connecting web 50 is formed as a channel-like light channel. An LED strip 52, which comprises a row of LEDs at a defined distance from one another, is screwed into this illuminant receptacle in the installed position.

Below the LED strip 52, the UGR aperture 54 is arranged, which, like the LED strip 52, is screwed by means not shown screws on the underside of the connecting web 50 of the illuminant carrier 46. The UGR aperture 54 is formed as an elongated injection molded part, which is basically leitierförmig with two mutually parallel longitudinal webs 46, between which extend at defined intervals transverse webs 58, which are constructed in a frustoconical cross-section. Radially outwardly projecting from the longitudinal webs 56 are integrally formed on both sides of this mounting webs 60 in one piece to the longitudinal webs, which also serve to receive mounting screws, not shown on the illuminant carrier 46. In installation position cover the transverse webs 58 of the UGR aperture 54 from the free area between two adjacent LEDs of the LED bar 52 and cause the desired glare, in the further context of the FIG. 31 will be described in more detail.

In addition to the UGR aperture 54, the optics also comprises two optical disks 62 made of translucent plastic, which are of trough-shaped design and can be snapped into the light channel of the illuminant carrier 46 in such a way that they enclose the UGR panel 54 and the LED strip 52 in the installed position. Also in In this case, made of light-tight plastic end caps 64 are detachably snapped onto the front ends of the cover plates. These end caps 64 prevent also in a light band system interconnected light band elements 44 an unwanted side flash of light and thus realize a regulated light radiation and glare.

In the middle between the two optical disks 62, the laminating element 64 is inserted. This is designed as a substantially rigid and plate-shaped plastic web, which is arranged in the installed position with its longitudinal direction transverse to the longitudinal direction of the light band element 44 between the two adjacent abutting sides of the optical discs 62 and thus covers the gap between these cover plates 62 from the inside. The laminating element 66 has on each longitudinal side at the front ends paired struts 68, which rest in the installed position on the end faces of the adjacent optical disks 62 and thus realize a resilient bias between the two optical disks 62 to avoid crackling noises. Furthermore, the middle region of the plastic web of the lamination element 66 is slightly raised relative to the two outer regions with the spring struts 68 arranged in pairs to adapt to the geometry of the cover disks 62.

The FIG. 30 The end caps 46 block the light emitted by the LEDs 70 light in the transition region of the end face against each other mounted light band elements 44. Below the end caps 64 lightens the optical discs 62nd due to partially totally reflecting light rays (L) on, so that the blinds are thereby laminated in the luminous state.

The FIG. 31 shows finally an enlarged, schematic longitudinal section of the optical system comprising the UGR aperture 54 and the optical disk 62, wherein this is simplified here compared to the actual embodiment, in which each optical disk 62 - Fig. 30 indicated - for light bundling on the top of the individual LEDs in the installed position and associated with each other has cut, concavely curved lenses. In the longitudinal direction of the luminaire, the EGR diaphragm 62 ensures that the light (L) emitted by the individual LEDs 70 is blocked in an angular range of 25 °. The UGR aperture 54 thus reflects the light mainly downwards, which is realized by the truncated pyramidal configuration of the transverse webs 58, which reflect the light rays substantially downwards by the inclination of the lateral reflection surfaces 72 of each transverse web 58. On the other hand, light beams which are not deflected by the lateral reflection surfaces of the transverse webs 58 are refracted at the desired angle by the optical disks 62 in order to realize the insertion.
