Description
[0001] The present invention relates to an elongated luminaire with a support plate for fastening current-carrying luminaire components, such as connection terminals, as well as a luminaire system equipped with this luminaire with a luminaire support rail accommodating the luminaire.
[0002] Elongated luminaires of the type mentioned above are generally known. These can be, for example, so-called light bars, which are used in elongated luminaire support rail systems. Such luminaires usually have an elongated luminaire carrier in which an elongated light source, such as an LED module, is housed to emit light. Optical elements, such as lenses, can be arranged in the light path of the light emitted by the light source in order to adjust the light emission characteristics as required. To accommodate it in the luminaire carrier, the light source can be inserted lengthwise into the luminaire carrier. In this case, the light source must then be secured to prevent it from accidentally slipping out. Additional fastening devices, such as screws, are usually used for this purpose.These can, for example, be guided through the light source and fastened in the light support to secure the light source in the desired position. It is also conceivable to provide separate fastening structures, such as locking pins or locking springs. The optical element can also be inserted into the light support in a similar manner. The optical element can then, for example, be provided with additional locking structures, such as locking hooks, which can snap into corresponding locking structures on the light support. The optical element can also be secured in place using the additional fastening means described above, similar to the light source.
[0003] Furthermore, additional components, such as current-carrying lighting components, are provided as needed. These are then often attached separately to the luminaire support, for example, by screwing.
[0004] Furthermore, such luminaires can have separate elements as a protective barrier against electric shock, for example, coverings that block access points (e.g., openings) in the luminaire support. These access points are used, for example, for assembly or maintenance, but should be blocked when the luminaire is in operation.
[0005] In addition, corresponding luminaires usually have fastening or locking elements which are attached to the luminaire support in order to lock it into the elongated luminaire support rail to form a luminaire system.
[0006] Therefore, numerous components are required to create a suitable luminaire, which must be prepared and secured in individual work steps. This requires a corresponding number of work steps for the defined positioning and securing of the components. Consequently, it is impossible or difficult to manufacture such luminaires using automated production and assembly steps.
[0007] US 2019 / 346 117 A1, US 2017 / 059 139 A1 and DE 10 2013 226 950 A1 disclose elongated luminaires.
[0008] It is therefore an object of the present invention to provide an elongated luminaire and a luminaire system equipped therewith and components thereof, which provide many functions with or in comparatively few components and can be assembled in a simple and safe manner; this preferably also in an automated manner.
[0009] This object is achieved by the subject matter of the independent claims. The dependent claims develop the central idea of the present invention in a particularly advantageous manner.
[0010] According to a first aspect, the present invention relates to an elongated luminaire which extends along a longitudinal axis. The luminaire has a luminaire support with a rear side and a front side. The luminaire support extends longitudinally with respect to the longitudinal axis between two axially opposite end faces. The luminaire furthermore has an elongated illuminant for emitting light at least via the front side of the luminaire support. Furthermore, the luminaire has a supporting plate for fastening current-carrying luminaire components. The luminaire support has, on its front side, a holding section for supporting the illuminant. The luminaire support also has, on at least one of the end faces, an open insertion region of the holding section, via which insertion region the illuminant can be slidably inserted or removed from the holding section in an insertion direction oriented parallel to the longitudinal axis.is inserted in order to be or be received therein in a form-fitting manner perpendicular to the longitudinal axis. The support plate has a fastening section with which the support plate can be or is fastened to the rear of the lamp support. Furthermore, the support plate has a blocking section which is formed integrally with the fastening section and which, when the support plate is fastened to the rear of the lamp support above the fastening section, extends at least partially in front of the insertion area in such a way as to secure the lamp received in the holding section against sliding out of the holding section via the insertion area against the insertion direction.
[0011] By means of a luminaire provided in this way, and in particular by providing a correspondingly designed support plate, several functions can be combined with a relatively small number of components. On the one hand, the support plate serves to secure current-carrying luminaire components, which can therefore preferably be provided together, which in turn facilitates the assembly and positioning of these components.
[0012] In the context of the present invention, "current-carrying luminaire components" are understood to mean, in particular, luminaire components which are themselves intended to carry and possibly also use electrical current (e.g. connection terminals or operating devices) or which are intended to accommodate corresponding current-carrying elements or devices (e.g. strain relief for the passage and fixing of electrical conductors / cables).
[0013] In addition, the support plate serves to secure the position of an inserted lamp, thus eliminating the need for complex fastening structures and fastening elements as well as corresponding fastening steps. By simply attaching the support plate, its functional sections - namely the fastening section and the blocking section - are positioned accordingly, so that several functions can be fulfilled or provided simultaneously with just this single fastening step. Since the support plate, with its blocking section, is designed to at least partially cover the sides of the inserted lamp, it can also serve as contact protection for the lamp. The same applies to the fastening section, which can be designed to cover corresponding access areas, for example to protect against electric shock.
[0014] The blocking section can extend in front of the entire insertion area when the support plate is attached to the rear of the lamp holder via the mounting section. This effectively prevents the lamp from slipping out of the holding section, while also providing effective contact protection.
[0015] The support plate can preferably be detachably connected to the luminaire body, preferably by means of a screw or a screw connection. This allows for easy installation. Likewise, the support plate can be easily removed or replaced if necessary—for example, during maintenance.
[0016] The support plate is preferably manufactured as a single piece from a single sheet metal material as a stamped and bent part. This allows the support plate to be manufactured in a simple, effective, and cost-effective manner.
[0017] The support plate itself, or in its longitudinal section, preferably has an L-shape. The support plate thus has a particularly simple yet functionally highly effective shape. The support plate can thus be manufactured easily and cost-effectively, while the corresponding functional areas—namely, the fastening section and the blocking section—can be easily provided.
[0018] The blocking section and the fastening section preferably extend away from each other at an angle to each other and particularly preferably enclose a right angle α. This simple shape of the support plate allows the two functional sections to be easily oriented relative to each other as needed. If they enclose a right angle, the previously described L-shape preferably results.
[0019] The blocking section preferably extends from an end edge, preferably a narrow side, of the fastening section. The support plate can thus be provided in a simple manner and as compactly as possible. If the blocking section is also provided on the narrow side of the fastening section, the fastening section can consequently be provided along the luminaire support and can thus be provided over a large area despite the compact design of the luminaire.
[0020] The blocking section and / or the fastening section preferably each extend in one plane. Thus, the two sections can be designed, for example, as plate-like structures. This results in a simple structure of the support with an overall compact yet effectively functional design.
[0021] Preferably, the blocking section extends from the mounting section to the front of the luminaire support when the support plate is attached to the rear of the luminaire support above the mounting section. Thus, despite its simple shape, the support plate can be positioned highly effectively while maintaining a compact luminaire design without compromising the light output to the front.
[0022] The luminaire can preferably further comprise an elongated optical element for influencing the light emitted by the illuminant. The optical element can, for example, comprise or form lenses and / or diffusers. The luminaire support is then further configured such that the optical element can be slidably inserted into the holding section lengthwise via the insertion region in the insertion direction, in order to be held therein in a form-fitting manner perpendicular to the longitudinal axis and preferably then in a light path of the light emitted by the illuminant. Thus, both the illuminant and the optical element can be accommodated in the luminaire support in the same way. This simple receptacle enables simple and preferably automated production and assembly.
[0023] The blocking section can preferably also be designed such that, when the support plate is fastened to the rear of the lamp support via the fastening section, it extends at least partially in front of the insertion area in order to further secure the optical element received in the holding section against sliding out of the holding section via the insertion area counter to the insertion direction. Thus, in addition to securing the lamp, the support plate can also be used to secure the optical element. This further increases the functionality of the support plate. Since no further precautions need to be taken or additional fastening means provided to secure the optical element, the structure of the lamp as a whole can be simplified and its manufacture and assembly can be further simplified.
[0024] The holding section preferably has a support section that supports the received illuminant on both sides of the longitudinal axis. Thus, a simple structure can be provided in the lamp body to effectively support the illuminant.
[0025] The holding section can preferably have a further support section that supports the accommodated optical element on both sides of the longitudinal axis. Thus, an optionally provided optical element can also be supported simply and effectively in the same way as the illuminant. The further support section can preferably be offset toward the front with respect to the support section, so that when the illuminant and the optical element are provided, they can be positioned in a defined and functionally coordinated arrangement. This simplifies assembly and reduces the risk of incorrect installation.
[0026] The holding section or, if present, its supporting section(s) can preferably have U-shaped rail sections open toward each other on both sides of the longitudinal axis for receiving the illuminant or optical element. This provides a simple structure for securely and effectively receiving the corresponding components.
[0027] The rail sections can preferably each extend parallel to the longitudinal axis; this is particularly preferred between the two end faces. This enables effective and secure support of the corresponding components via the rail sections. Alternatively or additionally, it is also conceivable for the rail sections to each comprise sub-sections distributed along the longitudinal axis. This allows for effective storage of the corresponding components in the holding section in a material-friendly manner.
[0028] The blocking section can have a projection section at an end distal to the fastening section, which extends in front of a portion of the insertion area when the support plate is fastened to the rear of the light support via the fastening section. Thus, desired areas of the insertion area can be covered in a defined manner, even when the support plate is manufactured in a material-saving manner. Preferably, the projection sections extend at least partially in front of the further support section and / or in front of the rail sections or into the rail sections. Thus, the projection sections can be provided in a targeted and effective manner.
[0029] The elongated light source can preferably comprise at least one LED module. LED modules are particularly characterized by high efficiency and longevity, as well as a compact design.
[0030] The LED module preferably comprises an elongated circuit board and at least one LED arranged thereon. If the LED module comprises multiple LEDs, these are preferably arranged in one or more rows on the circuit board, preferably extending parallel to the longitudinal axis. Preferably, two parallel longitudinal edges of the circuit board can serve as supporting means in the holding section. Thus, the illuminant can be effectively accommodated in the light carrier in a simple and compact manner.
[0031] The support plate, and preferably at least its fastening section, can preferably have fastening structures for attaching current-carrying lighting components. These facilitate the provision of corresponding components on the support plate.
[0032] The fastening structures can comprise through-openings and / or recesses in the supporting sheet, which are particularly preferably formed in the supporting sheet by means of separation processes. Thus, simple and easily provided fastening structures can be provided directly during the production of the supporting sheet (for example, in a joint punching and bending process).
[0033] If access openings are provided, they can also be used as a guide for the correct positioning of the support plate on the light support. For example, an operator can see an assembly marking provided behind it on the light support through the access openings, thus ensuring the correct position of the support plate.
[0034] The luminaire can further comprise current-carrying luminaire components that can be or are directly fastened to the support plate and preferably its fastening section. The current-carrying luminaire components can preferably be or are detachably fastened to the support plate. The fastening structures described above can particularly preferably be used to fasten the current-carrying luminaire components to the support plate. The current-carrying luminaire components can then preferably have locking structures corresponding to the fastening structures or other structures or elements for (preferably positive and / or non-positive) fastening. Thus, the luminaire can be equipped with corresponding components in any desired manner.Since these components are advantageously combined on the support plate, handling of these components is particularly easy while maintaining their relative positioning and orientation. This also allows a luminaire equipped with them to be easily manufactured, preferably using an automated production or assembly process.
[0035] The current-carrying lighting components can be, for example, a connection terminal and / or a strain relief for securing a cable and / or a status LED and the like. A corresponding status LED can, for example, have a fastening structure (preferably as an element corresponding to the fastening structures), such as a retaining hook or a retaining wire, which is then appropriately fastened in the support plate. This can then, for example, be hooked into the fastening structures accordingly in order to securely hold the status LED in a defined position - for example, facing the front. This can further increase the functionality of the support plate.
[0036] According to a further aspect, the present invention further relates to a lighting system (also referred to as a "lighting support rail system" within the scope of the present invention), which, in addition to the previously described luminaire according to the invention, further comprises an elongated luminaire support rail for receiving the luminaire. Thus, the luminaire is then preferably accommodated accordingly in the luminaire support rail. Thus, the advantages of the luminaire can also be transferred to a higher-level lighting system. This can then also be manufactured or assembled in a simple manner, for example, in an automated manner.
[0037] The lighting system preferably further comprises a retaining spring with a fastening leg for attachment to the light support and at least one (preferably two opposing) locking legs for lockingly receiving the light in the light support rail. This provides a simple means of securely mounting the light in the light support rail.
[0038] The retaining spring can particularly preferably be formed integrally with the support plate. The fastening section can preferably comprise or form the fastening leg. Since additional functions can thus be integrated into the support plate, the overall structure of the luminaire or luminaire system is further simplified.
[0039] The lighting system can further comprise a fastening screw for fastening the retaining spring to the light body. The fastening leg can then preferably comprise a through-opening for receiving or passing through a screw shaft of the fastening screw. The fastening leg can further comprise a slot extending away from the through-opening. In addition, the fastening leg can comprise an embossing in the region of the slot, which is provided in such a way that an underside of a screw head of the fastening screw, whose screw shaft is received in the through-opening, rests on the slotted embossing when the retaining spring is fastened. This slotted embossing in the region of the support of the screw head can create a secure and mechanical support for the screw in order to achieve a high tightening torque of the screw for secure fastening of the retaining spring.
[0040] The underside of the screw head can preferably have a serration under the head, which in conjunction with the slotted embossing allows a particularly high tightening torque of the screw to be achieved.
[0041] Furthermore, a retaining spring is provided, for example, for the locking fastening of a luminaire in a luminaire support rail. The retaining spring is made in one piece from spring steel. The retaining spring has a fastening leg extending longitudinally along an axis of extension. Furthermore, the retaining spring has two locking legs with a locking contour, which extend axially on both sides of the fastening leg and are angled to the same side with respect to the axis of extension. The retaining spring thus has a substantially C-shape or U-shape. The fastening leg has a through-opening for receiving a screw shaft of a fastening screw for fastening the retaining spring. The fastening leg also has a slot extending away from the through-opening.The fastening leg further has an embossing in the area of the slot, which is provided in such a way that an underside of a screw head of a fastening screw received with its screw shaft in the through-hole rests on the slotted embossing when the retaining spring is fastened.
[0042] This slotted embossing provides a secure support for a screw head to achieve a defined tightening torque. This safely and easily prevents a screw from slipping during tightening (a so-called perpetual handling) even when using a retaining spring made of spring steel, and instead achieves a defined target torque. Because the embossing is slotted, the edges of the embossing created in this way, which flank the slot, form a secure support edge in the direction of screw rotation, allowing a high tightening torque. The use of the integrally provided slotted embossing also eliminates the need for additional components, such as washers for inserting between the screw head and the retaining spring. This, in turn, simplifies assembly and reduces the number of parts as well as manufacturing and product costs.This significantly improves the overall assembly of the retaining spring during manufacturing or production, as the slotted embossing enables a consistent and reproducible tightening torque. If the retaining spring is manufactured from a suitable spring steel, preferably through a stamping and bending process, the slotted embossing can be incorporated directly into the spring's manufacturing process.
[0043] The embossing can preferably be provided on a side of the fastening leg facing away from the locking legs. Thus, the embossing can be provided on a side that is easily accessible for a fastening screw intended for securing the retaining spring.
[0044] The fastening leg can preferably have flank sections protruding on both sides relative to the extension axis and in the same direction as the embossing. These flank sections, together with the fastening leg, form a receiving space for the screw head of the fastening screw, whose screw shaft is received in the through-hole. This allows the screw head to be countersunk in a simple, space-saving manner. Furthermore, the connection point of the fastening element with the retaining spring is thus securely protected.
[0045] The retaining spring described above can correspond to the retaining spring of the previously described lighting system or the associated light.

The figures show side views, some of which are labeled with letters, with the following letters indicating the following views: (A) a side view, (B) a front view (for the light: viewed in the direction of insertion), (C) a top view (for the light: viewed from the rear), (D) a bottom view (for the light: viewed from the front), (E) a rear view (for the light: viewed in the direction opposite to the insertion direction).

[0047] The figures show different embodiments of an elongated luminaire 1 according to the invention as well as a luminaire system 100 equipped therewith and components thereof.
[0048] Especially in the Fig. 1 and 2 - but also in the Fig. 18, 19 , 26 und 27 - luminaires 1 according to the present invention are shown. The elongated luminaire 1 according to the invention extends along a longitudinal axis X, as shown in particular in the Fig. 1 , 2 , 19 and 27 is shown.
[0049] The luminaire 1 has a luminaire support 2 with a rear side 20 and a front side 21. The luminaire support 2 extends longitudinally with respect to the longitudinal axis X between two axially opposite end faces 22, as can be seen in particular from the Fig. 1 is evident.
[0050] Furthermore, the luminaire 1 has an elongated illuminant 3 for emitting light at least via the front side 21 of the luminaire support 2; see, for example, a main light emission direction H in the Fig. 1 , 2 , 18, 19 , 26 und 27 . The elongated illuminant 3 has at least one LED module 3 or forms the same (cf. Fig. 2E and 26). The LED module 3 preferably has an elongated circuit board 30 and at least one LED 31 arranged thereon. The LEDs 31 are preferably provided on the circuit board 30 in one or more rows, preferably aligned parallel to the longitudinal axis X.
[0051] The luminaire 1 further comprises a support plate 4 for fastening current-carrying luminaire components 5. The support plate 4 is particularly in the Fig. 1 and 2 and 4 to 19 are visible.
[0052] The current-carrying luminaire components 5 can, for example, be a connection terminal 50 (cf. Fig. 1 , 2 , 5II , 6-19 ) and / or a strain relief 51 (cf. Fig. 5III , 14-17 ) for passing through an electrical cable and / or a status LED 52 (cf. Fig. 5II , 10-13 , 16-19) and the like. The status LED 52 may already be provided wired, as shown in the Fig. 5II , 12 , 13 , 16-19 shown electrical conductor 520. The aforementioned current-carrying luminaire components 5 are particularly shown in the Fig. 5II , 16 and 17 shown in combination on the support plate. The luminaire 1 can therefore preferably have these current-carrying luminaire components 5. The current-carrying luminaire components 5 can be or are attached directly to the support plate 4; this is preferably detachable, as can also be seen from the figures.
[0053] As in particular the Fig. 4 As can be seen, the support plate 4 can have fastening structures 6 for the - preferably detachable - fastening of the current-carrying luminaire components 5. As can be seen from the Fig. 4 As can also be seen, the fastening structures 6 can have through-openings 60 and / or recesses 61 in the support plate 4, which are preferably formed by separation processes in the support plate 4.
[0054] The current-carrying luminaire components 5 can preferably have structures or elements corresponding to the fastening structures 6 for (removable) fastening to / on the support plate 4. These structures can have locking structures 53, 54. For example, these locking structures can have a locking pin 53, as is shown for the connection terminal 50, for example, in the Fig. 2E , 7 , 9 , 11 , 13 , 15 and 17 can be seen. The locking pin 53 can then, for example, engage or lock into a round opening 60 in the support plate 4. The locking structures can also have other locking hooks 54, as is the case for the strain relief 51, for example, in the Fig. 15 and 17 can be seen. In the exemplary embodiments shown here, the locking structures can then, for example, engage or lock into a rectangular opening 60 in the support plate 4. In the Fig. 5II , 10-13 , 16 and 17In the exemplary embodiments illustrated, the status LED 52 has, for example, a fastening structure 55 as an element corresponding to the fastening structures 6. This fastening structure 55 can have a holding hook or a holding wire, which at one end holds the light source 56 of the status LED 52 with a positioning section 57 and is fastened with the other end in the support plate 4. For this purpose, the other end has, for example, a hook section 58, with which the fastening structure 55 is suspended in one of the through-openings 60 in the support plate 4. The fastening structure 55 further has a clamping section 59 between the light source 56 and the hook section 58, with which the fastening structure 55, which is suspended in the support plate 4 with the hook section 58, can be clamped at another point on the support plate 4 and thus fixed in its position.For this purpose, for example, the clamping section 59 is guided into a recess 61, thus clamping the fastening structure 55 between the through-opening 60 on the one hand and the recess 61 on the other. Thus, the fastening structure 55 can preferably be suspended or clamped into the fastening structures 60, 61 accordingly in order to securely hold the status LED 52 in a defined position—here, for example, directed toward the front side 21 of the lamp 1. As shown in . Fig. 18 und 19 As can be seen, the status LED 52 can be positioned, for example, directly behind a lamp cover 108 in order to be visible from the outside when required (i.e. when the light source 56 is in operation).
[0055] The support plate 4 is preferably made in one piece as a stamped and bent part from a sheet material B, as shown by way of example in the Fig. 3 is shown. In Fig. 3 The sheet material B is shown after a punching step, in which the structural sections (for example the fastening structures 6) and the basic contour of the support sheet 4 have already been introduced. In a subsequent bending step, the support sheet is bent into the desired shape, as shown, for example, in the Fig. 4 shown and described below.
[0056] As well as the Fig. 3 As can be seen, the support plate 4 can be provided with a note. This can, for example, be printed on the support plate 4, glued on, or, as shown here, incorporated directly into the support plate 4 as an embossed mark P. This way, for example, safety instructions or operating instructions (e.g., for the correct connection of conductors or other components) can be provided directly on the support plate 4.
[0057] As can be seen in particular from the Fig. 4b As can be seen, the support plate 4 can have an L-shape; here in a side view or in a longitudinal section view.
[0058] As can be seen particularly from the frontal rear view of the lamp Fig. 2E and the views in the Fig. 26 und 27 As can be seen, the lamp support 2 has on its front side 21 (the lower side in the figures mentioned) a holding section 7 for supporting the lighting means 3. The lamp support 2 further has on at least one of its end faces 22 an open insertion region 70 of the holding section 7, via which the lighting means 3 can be guided into the holding section 7 in an insertion direction E oriented parallel to the longitudinal axis X, in order to be positively supported therein perpendicular to the longitudinal axis X.
[0059] As well as in particular the Fig. 2E , 26 und 27 As can be seen, the holding section 7 can have a support section 71 which supports the received illuminant 3 on both sides of the longitudinal axis X. The holding section 7 or its support section 71 preferably has U-shaped rail sections 72 on both sides of the longitudinal axis X and open towards one another for receiving the illuminant 3. The two rail sections 72 directed towards one another here thus delimit a receiving space on both sides for receiving the illuminant 3 therebetween.
[0060] Like the Fig. 1 , 2 , 18, 19 , 26 und 27 As can also be seen, the luminaire 1 can further comprise an elongated optical element 8 for influencing the light emitted by the illuminant 3. For this purpose, the optical element 8 can, for example, comprise lenses 80 and / or further optical sections such as diffuser sections and the like. The luminaire carrier 2 is then preferably further designed such that the optical element 8 can be slidably inserted longitudinally via the insertion region 70 in the insertion direction E into the holding section 7 in order to be received therein in a form-fitting manner perpendicular to the longitudinal axis X and in a light path of the light emitted by the illuminant 3.
[0061] The holding section 7 can then preferably have a further support section 73, which supports the received optical element 8 on both sides of the longitudinal axis X, wherein the further support section 73 is arranged offset with respect to the support section 71, preferably towards the front side 21, as is particularly the case with the Fig. 2E , 26 und 27 can be seen.
[0062] The holding section 7 or its (further) support sections 73 can then also have U-shaped rail sections 74, open toward each other, on both sides of the longitudinal axis X for receiving the optical element 8. The two rail sections 74, directed toward each other here, thus delimit a further receiving space on both sides for receiving the illuminant 3 therebetween. The further receiving space can, as shown here, directly adjoin the receiving space delimited by the rail sections 72, so that they preferably form a contiguous space in which the illuminant 3 and the optical element 8 can be arranged; in particular, arranged one behind the other with respect to the main light emission direction H.
[0063] The rail sections 72, 74 preferably each extend parallel to the longitudinal axis X and particularly preferably between the two end faces 22. In a preferred embodiment not shown here, it is conceivable that the rail sections 72, 74 each have rail subsections distributed along the longitudinal axis X.
[0064] As well as in particular the Fig. 2E and 26 As can be seen, two parallel longitudinal edges 32 of the circuit board 30 preferably serve for supporting reception in the holding section 7.
[0065] The support plate 4 has a fastening section 40 with which the support plate 4 can be fastened to the rear side 20 of the light support 2 or is fastened there.

Particularly preferably, the support plate 4 and with it all its functions and preferably also the current-carrying light components 5 can be fastened with just one fastening means (here a central fastening screw 9). It is also conceivable for the support plate 4 and the light support 2 to each have integrally formed fastening structures, which make it possible to fasten the support plate 4 to the light support 2 without separate fastening means. Other known fastening options are also conceivable.
[0066] The fastening section 40 preferably extends in a plane, as can be seen, for example, from the Fig. 4 is evident.
[0067] The fastening section 40 can have any contour suitable for the intended purpose. Fig. 6 and 8 Two different contours of the fastening section 40 are shown as examples.
[0068] As exemplified by the Fig. 4 As can be seen, in particular the fastening section 40 of the support plate 4 has the fastening structures 6. In this respect, the current-carrying luminaire components 5 are preferably directly fastened or fastened to the fastening section 40 - more preferably via its fastening structures 6 - and this is particularly preferably detachable. In this regard, reference is made to the Fig. 1 , 2 , and 5-19 referred to.
[0069] The support plate 4 further comprises a blocking section 41 formed integrally with the fastening section 40. The blocking section 41 may also preferably extend in one plane, as may the Fig. 4 Likewise, the blocking section 41 can have any contour that is suitable for the intended purpose. Fig. 6 and 8 Two different contours of the blocking section 41 are shown as examples.
[0070] The blocking section 41 extends, when the support plate 4 is fastened to the rear side 20 of the lamp carrier 2 via the fastening section 40, at least partially in front of the insertion area 70, so that the illuminant 3 accommodated in the holding section 7 and optionally also the optical element 8 accommodated in the holding section 7 is / are secured against sliding out of the holding section 7 via the insertion area 70 against the insertion direction E. This is particularly evident from the Fig. 1 , 2B , 18 und 19 visible. The blocking section 41 can preferably extend in front of the entire insertion area 7 when the support plate 4 is fastened to the rear side 20 of the lamp support 2 above the fastening section 40. In the exemplary embodiments illustrated here, the blocking section preferably extends at least completely in front of the receiving space accommodating the lamp 3 and further partially in front of the further receiving space accommodating the optical element 8. Thus, at least the lamp 3, which conducts electrical current during operation, can be accommodated in the lamp support 2 in a manner that is safely protected from contact.
[0071] As in particular the Fig. 4 As can be seen, the blocking section 41 and the fastening section 40 can extend away from each other at an angle; here preferably enclose a right angle α, as is particularly the case with the Fig. 4A can be seen.
[0072] The blocking section 41 can preferably extend from a front edge 42, preferably a narrow side, of the fastening section 40, as is also the case with the Fig. 4 can be seen.
[0073] As in particular the Fig. 1 and 19 As can be seen, when the support plate 4 is fastened to the rear side 20 of the lamp support 2 via the fastening section 40, the blocking section 41 can extend from the fastening section 40 to the front side 21 of the lamp support 2.
[0074] The blocking section 41 can preferably have a projection section 43 at an end distal to the fastening section 40, which, when the support plate 4 is fastened to the rear side 20 of the lamp support 2 via the fastening section 40, extends in front of a part of the insertion area 70, preferably at least partially in front of the further receiving space or the further support section 73 and / or in front of the rail sections 72, 74 or - as shown here - into the rail sections 72, 74. In the exemplary embodiment shown here, the projection sections 43 are laterally flared out in a wing-like manner with respect to the longitudinal axis X and, viewed in the direction of the longitudinal axis X, only laterally cover outer, front-side edge regions of the optical element 8 in order to effectively secure the optical element 8 in the holding section 7, while at the same time the light output is impaired as little as possible by the blocking section 41.
[0075] With reference to the Fig. 18 und 19 The present invention is further directed to a lighting system 100 which, in addition to the previously described luminaire 1, also has an elongated luminaire support rail 101 for receiving the luminaire 1. In the exemplary embodiment shown here, the elongated luminaire support rail 101 is provided as an elongated, U-shaped profile element 101. For this purpose, the profile element or the luminaire support rail 101 preferably has two lateral side legs 103 and a connecting leg 104 connecting these at the rear. The luminaire support rail 101 defines an interior space I in which the luminaire 1 is completely received. For this purpose, the luminaire support rail 101 can have structural sections 105 directed towards its interior space I or projecting into the interior space I, which structural sections can preferably be used to fasten the luminaire 1 and / or other elements.The luminaire 1 is preferably provided with its main light emission direction H directed toward the opening 102 defined by the luminaire support rail 101 or, in this case, its U-shaped profile, in order to emit the light emitted by the luminaire 1 for illumination via the opening 102. Optical luminaire elements 108 can be provided in the light path of the luminaire 1—and preferably in the opening 102—such as, for example, a simple luminaire cover or a diffuser plate or a lens or lens plate, and the like.
[0076] The light support 2 can have light-directing elements 23, such as a reflector here, on its front side 21. The light-directing elements 23 are formed integrally with the light support 2, for example. The light-directing elements 23 serve to provide defined light direction from the light source 3 supported in the holding section 7.
[0077] As in particular the Fig. 18 but also the Fig. 26 und 27 As can be seen, the lighting system 100 can further comprise a retaining spring 10 with a fastening leg 11 for fastening to the lighting support 2 and at least one and here two (preferably opposite with respect to the fastening leg 11) locking legs 12 for lockingly receiving the lighting device 1 in the lighting support rail 101 - here, for example, via the structural sections 105. In a preferred embodiment not shown here, the retaining spring 10 can be formed integrally in one piece with the support plate 4, in which case the fastening section 40 then preferably has or forms the fastening leg 11.
[0078] The retaining spring 10 is described in more detail below.
[0079] The retaining spring 10 is made of a single piece of spring steel. For example, the retaining spring 10 can be produced in a stamping and bending process. Fig. 20 bis 25 show two embodiments of a retaining spring 10 according to the invention (cf. Fig. 20 , 22 , 24, 25 ) or stamped parts S for producing a corresponding retaining spring 10 after a stamping process (and embossing process) and before a corresponding bending process (cf. Fig. 21 and 23 ).
[0080] The retaining spring 10 has the fastening leg 11, which here extends longitudinally along an extension axis Y.
[0081] The retaining spring 10 further comprises two locking legs 12 extending axially on both sides of the fastening leg 11 at an angle to the same side with respect to the extension axis Y. The locking legs 12 have a locking contour 13, by means of which the retaining spring 10 can be locked, for example, in the luminaire support rail 101 or with its structural sections 105, in order to fasten a component fastened via the fastening leg 11 (here the luminaire 1 or its luminaire support 2) in a locking manner. Since the fastening leg 11 can be fastened to the component 1 / 2 to be fastened, the fastening leg 11 then preferably forms a counterbearing for a resilient pivoting out of the locking legs 12 or their locking contours, which can thus act as detents.
[0082] In the transition area between the fastening leg 11 and the locking leg 12, stabilizing embossments 14 can preferably be provided in order to improve the spring force of the locking legs 12 for securing them against the lamp support 2. The stabilizing embossments 14 act here as a type of stiffening structure.
[0083] As in particular the Fig. 20 and 22C As can be seen, the fastening leg 11 can have a through-opening 15, which is intended to receive a screw shaft 91 of a Fig. 26 und 27 shown fastening screw 90 for fastening the retaining spring 10 - here, for example, to the lamp 1 or its lamp holder 2.
[0084] The fastening leg 11 further has a slot 16 extending away from the through-opening 15. In the embodiment of the Fig. 20 bis 22 this slot 16 is designed as a cross slot. In the embodiment of the Fig. 23 bis 25 is the slot, as in particular the Fig. 23 can be seen, here designed as a longitudinal slot.
[0085] The fastening leg 11 has an embossing 17 in the area of the slot 16, which is provided in such a way that an underside of a screw head 92 of a fastening screw 90 received with its screw shaft 91 in the through-opening 15 rests on the slotted embossing 17 when the retaining spring 10 is fastened, as can be seen from the Fig. 26 und 27 can be seen.
[0086] The embossing 17 is preferably provided on a side 18 of the fastening leg 11 facing away from the locking legs 12.
[0087] As in particular the Fig. 20 As can be seen, the fastening leg 11 can have flank sections 19 projecting on both sides with respect to the extension axis Y and in the same direction as the embossing 17, which flank sections 19, together with the fastening leg 11, have a receiving space R for receiving the screw head 92 of the fastening screw 90 received with its screw shaft 91 in the through opening 15.
[0088] The lighting system 100 equipped with the retaining spring 10 or the luminaire 1 equipped therewith preferably further comprises the aforementioned fastening screw 90 for fastening the retaining spring 10 to the luminaire body 2, as is particularly the case with Fig. 26 und 27 can be seen. The retaining spring 10 can then preferably be designed as described above. The fastening leg 11 then has the through-opening for receiving the screw shaft 91 of the fastening screw 90. The fastening leg then in turn has the slot 16 extending away from the through-opening 15. The fastening leg 11 then in turn has the embossing 17 in the area of the slot 16, which is provided in such a way that the underside of the screw head 92 of the fastening screw 90, which has its screw shaft 91 received in the through-opening 15, rests on the slotted embossing 17 when the retaining spring 10 is fastened, as well as the Fig. 26 und 27can be seen. The underside of the screw head 92 can preferably have a lower head serration (not shown), with which it then rests on the slotted embossing 17, whereby in conjunction with the slotted embossing 17 a particularly high tightening torque of the screw 90 can then be achieved.
