Definitions

  • 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 that accommodates the luminaire.
  • the present invention also relates to a retaining spring for fastening the luminaire in the luminaire support rail.
  • Elongated lights of the type mentioned at the beginning are generally known. These can be, for example, so-called light bars, which are used in elongated light support rail systems. Such lights usually have an elongated light carrier in which an elongated light source, such as an LED module, is accommodated 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 light carrier, the light source can be inserted lengthways into the light carrier. In this case, the light source must then be secured against unwanted slipping out. Additional fastening means such as screws are usually used for this purpose.
  • optical element can, for example, be guided through the light source and fastened in the light carrier in order to fix 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 carrier in a similar way. The optical element can then be provided with additional locking structures, such as locking hooks, which can snap into corresponding locking structures on the side of the light carrier. The optical element can also be fixed in place using the additional fastening means described above, similar to the light source.
  • Such luminaires can have separate elements as a protective barrier against electric shock, which, for example, act as a cover to block corresponding access options (e.g. openings) in the luminaire carrier. These access options are used for assembly or maintenance, for example, but should be blocked when the luminaire is in operation.
  • access options e.g. openings
  • corresponding luminaires usually have fastening or locking elements which are attached to the luminaire carrier in order to lock it into the elongated luminaire support rail to form a luminaire system.
  • the present invention relates to an elongated lamp which extends along a longitudinal axis.
  • the lamp has a lamp carrier with a rear side and a front side.
  • the lamp carrier extends longitudinally with respect to the longitudinal axis between two axially opposite end faces.
  • the lamp also has an elongated lamp for emitting light at least over the front side of the lamp carrier.
  • the lamp also has a support plate for fastening current-carrying lamp components.
  • the lamp carrier has a holding section on its front side for supportingly receiving the lamp.
  • the lamp carrier also has an open insertion area of the holding section on at least one of the end faces, via which the lamp can be slidably inserted into the holding section in an insertion direction oriented parallel to the longitudinal axis in order to 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 fastened or fastened to the rear side of the lamp carrier.
  • the support plate has a blocking section which is formed in one piece with the fastening section and which, when the support plate is fastened to the rear side of the lamp carrier above the fastening section, extends at least partially in front of the insertion region in such a way as to secure the light source received in the holding section against sliding out of the holding section via the insertion region against the insertion direction.
  • the support plate serves to attach current-carrying lamp components, which can therefore preferably be provided together, which in turn facilitates the assembly of these components and their positioning.
  • current-carrying luminaire components are understood to mean in particular those luminaire components which are themselves intended to conduct 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).
  • the support plate serves to secure the position of an inserted lamp, so that complex fastening structures and fastening elements as well as corresponding fastening steps are not necessary.
  • 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 one fastening step.
  • the support plate can also serve as contact protection for the lamp because its blocking section is designed to at least partially cover the inserted lamp on the side.
  • the fastening section which can be designed if necessary in such a way that it can cover corresponding access areas, for example to protect against electric shock.
  • the blocking section can extend in front of the entire insertion area when the support plate is attached to the rear of the lamp carrier via the fastening section. This means that the lamp can be effectively secured against slipping out of the holding section, while at the same time providing effective protection against contact.
  • the support plate can preferably be detachably connected to the lamp body, preferably by means of a screw or a screw connection. In this way, the support plate can be easily installed. The support plate can also be easily removed or replaced if necessary - for example in the event of maintenance.
  • the support plate is preferably made in one piece as a stamped and bent part from a sheet metal material. This means that the support plate can be manufactured in a simple, effective and cost-effective manner.
  • the support plate itself or in the longitudinal section preferably has an L-shape.
  • the support plate therefore has a particularly simple but functionally highly effective shape.
  • the support plate can thus be manufactured easily and inexpensively, while the corresponding functional areas - namely the fastening section and the blocking section - can be easily provided.
  • 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 ⁇ .
  • the two functional sections mentioned can be easily provided oriented to each other as required. If they enclose a right angle, this preferably results in the L-shape described above.
  • the blocking section preferably extends from a front 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 lamp support and can thus be provided over a large area despite the compact design of the lamp.
  • the blocking section and/or the fastening section preferably each extend in one plane.
  • the two sections can therefore be designed like plates, for example. This results in a simple structure of the carrier with an overall compact but effectively functional design.
  • the blocking section preferably extends from the fastening section to the front of the lamp support when the support plate is fastened to the rear of the lamp support above the fastening section.
  • the lamp can preferably also have an elongated optical element for influencing the light emitted by the lamp.
  • the optical element can, for example, have lenses and/or diffusers or form these.
  • the lamp carrier is then further designed such that the optical element can be inserted into the holding section in a sliding manner along the insertion area in the insertion direction, in order to be held therein in a form-fitting manner perpendicular to the longitudinal axis and then preferably in a light path of the light emitted by the lamp.
  • both the lamp and the optical element can be held in the same way in the lamp carrier. This simple holding enables simple and preferably automated production or assembly.
  • the blocking section can preferably also be designed in such a way that, when the support plate is fastened to the rear of the lamp carrier via the fastening section, it extends at least partially in front of the insertion area in order to also secure the optical element held in the holding section against sliding out of the holding section via the insertion area against the insertion direction.
  • the support plate can be used not only to secure the light source, but also to secure the optical element. This means that the functionality of the support plate can be further increased.
  • the structure of the lamp as a whole can be simplified and its manufacture and assembly can be further simplified.
  • the holding section preferably has a support section which supports the received illuminant on both sides of the longitudinal axis.
  • the holding section can preferably have a further support section which supports the accommodated optical element on both sides of the longitudinal axis. This means that an optionally provided optical element can also be supported simply and effectively in the same way as the light source.
  • the further support section can preferably be arranged offset towards the front with respect to the support section, so that when the light source and the optical element are provided, they can be placed in a defined and functionally coordinated arrangement. This simplifies assembly and reduces the risk of incorrect installation.
  • the holding section or, if present, its support section or sections can preferably have U-shaped rail sections that are open towards each other on both sides of the longitudinal axis for receiving the light source or the optical element. This makes it possible to provide a simple structure for safely and effectively receiving the corresponding components.
  • the rail sections can preferably each extend parallel to the longitudinal axis; this is particularly preferred between the two end faces. This enables the corresponding components to be held effectively and securely via the rail sections. Alternatively or additionally, it is also conceivable for the rail sections to each have rail sections distributed along the longitudinal axis. This enables the corresponding components to be stored effectively in the holding section in a way that protects the material.
  • the blocking section can have a projection section at an end distal to the fastening section, which extends in front of a part of the insertion area when the support plate is fastened to the rear of the light carrier via the fastening section. This means that desired areas of the insertion area can be covered in a defined manner even when the support plate is manufactured in a way that protects the material.
  • the projection sections preferably extend at least partially in front of the further support section and/or in front of the rail sections or into the rail sections. This means that the projection sections can be provided in a targeted and effective manner.
  • the elongated light source can preferably have at least one LED module.
  • LED modules are particularly characterized by high efficiency and durability as well as a compact design.
  • the LED module preferably has an elongated circuit board and at least one LED arranged thereon. If the LED module has several 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 for supporting accommodation in the holding section. The light source can thus be accommodated effectively in the light carrier in a simple and compact manner.
  • the support plate and preferably at least its fastening section can preferably have fastening structures for fastening current-carrying lighting components. These make it easier to provide corresponding components on the support plate.
  • the fastening structures can have through-openings and/or recesses in the support plate, which are particularly preferably formed in the support plate by means of separation processes.
  • simple and easy-to-provide fastening structures can be provided directly during the manufacture of the support plate (for example in a common punching and bending process).
  • through-openings can preferably also be used as an orientation aid for the correct positioning of the support plate on the light carrier. For example, an operator can see an assembly marking provided behind it on the light carrier through the through-openings and thus ensure that the support plate is in the correct position.
  • the luminaire can also have current-carrying luminaire components which can be or are directly fastened to the support plate and preferably its fastening section.
  • the current-carrying luminaire components can preferably be or be fastened detachably 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 fastening (preferably positive and/or non-positive).
  • the luminaire can thus be equipped with corresponding components in any manner. Since these are advantageously combined on the support plate, handling these components while maintaining their relative positioning and orientation to one another is particularly easy. A luminaire equipped with them can therefore also be easily manufactured, preferably in an automated manufacturing or assembly process.
  • 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 (as an element that preferably corresponds to the fastening structures), such as a retaining hook or a retaining wire, which is then fastened accordingly in the support plate. This can then, for example, be hooked into the fastening structures accordingly in order to hold the status LED securely in a defined position - for example facing the front. The functionality of the support plate can thus be increased even further.
  • the present invention further relates to a lighting system (also referred to as a "lighting support rail system" in the context of the present invention), which, in addition to the previously described light according to the invention, also has an elongated light support rail for receiving the light. The light is then preferably received in the light support rail accordingly.
  • a lighting system also referred to as a "lighting support rail system” in the context of the present invention
  • 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 automatically.
  • the lighting system preferably also has a retaining spring with a fastening leg for fastening to the lighting support and at least one (preferably two opposing) locking legs for lockingly holding the lighting in the lighting support rail. This provides a simple way of securely holding the lighting in the lighting support rail.
  • the retaining spring can particularly preferably be formed integrally with the support plate.
  • the fastening section can preferably have or form the fastening leg. Since further functions can thus be integrated into the support plate, the overall structure of the lamp or the lighting system is further simplified.
  • the lighting system can also have a fastening screw for fastening the retaining spring to the lighting body.
  • the fastening leg can then preferably have a through-opening for receiving or for passing through a screw shaft of the fastening screw.
  • the fastening leg can also have a slot extending away from the through-opening.
  • the fastening leg can have an embossing in the area of the slot, which is provided in such a way that an underside of a screw head of the fastening screw, which has its screw shaft received in the through-opening, rests on the slotted embossing when the retaining spring is fastened.
  • This slotted embossing in the area 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.
  • the underside of the screw head can preferably have a underhead serration, which in conjunction with the slotted embossing allows a particularly high tightening torque of the screw to be achieved.
  • the present invention further relates to a retaining spring, for example for the latching fastening of a lamp in a lamp support rail.
  • the retaining spring is made in one piece from spring steel.
  • the retaining spring has a fastening leg extending longitudinally along an extension axis.
  • the retaining spring has two latching legs extending axially on both sides of the fastening leg to the same side at an angle with respect to the extension axis, with a locking contour.
  • the retaining spring thus has a substantially C-shape or U-shape.
  • the fastening leg has a through-hole 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-hole.
  • the fastening leg also 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.
  • This slotted embossing can be used to provide a secure support for a screw head to achieve a defined tightening torque. This means that even when using a retaining spring made of spring steel, the screw can be prevented from slipping during tightening (a so-called perpetual handling) in a safe and simple manner and a defined target torque can be achieved. Since the embossing is slotted, the edges of the embossing that are created in this way and flank the slot form a secure support edge in the direction of rotation of the screw, which allows a high tightening torque. By using the integrally provided slotted embossing, additional components such as washers for inserting between the screw head and the retaining spring can also be dispensed with.
  • the retaining spring in manufacturing or production can be significantly improved, since the slotted embossing enables a constant and reproducible tightening torque. If the retaining spring is preferably manufactured from a corresponding spring steel by a punching and bending process, the slotted embossing can be provided directly in the manufacturing process of the spring.
  • the embossing can preferably be provided on a side of the fastening leg facing away from the locking legs.
  • the embossing can thus be provided on a side which is easily accessible for a fastening screw to be provided for fastening the retaining spring.
  • the fastening leg can preferably have flank sections protruding on both sides with respect to the axis of extension and in the same direction as the embossing, which flank sections have a receiving space with the fastening leg for receiving the screw head of the fastening screw received with its screw shaft in the through-opening.
  • the screw head can thus be countersunk in a simple manner to save space.
  • the connection point of the fastening means with the retaining spring is thus provided in a safely protected manner.
  • the retaining spring described above can correspond to the retaining spring of the lighting system or the associated light also described above.
