Description

manual

[0001] The present invention relates to a mounting ring for recessed lighting fixtures, which enables the lighting fixtures to be mounted in recesses of assembly structures such as walls, ceilings, or floors.

[0002] Recessed luminaires are typically used in lighting systems where there are recesses in the ceiling or corresponding walls or floors where the luminaires are mounted. Currently known mounting rings for recessed luminaires are integrally formed, such that components such as the ring element and two rods are integrally formed. The rods enable clamping of the mounting ring because they form guide elements for corresponding latching arms. These guide elements interact with the inner side (top surface) of the corresponding assembly structure and thereby press the flange-like section of the ring element against the visible outer side (bottom surface) of the mounting surface, thus securing the mounting ring. The combination of the latching arms and the mounting ring thus forms the mounting system.

[0003] The general principle of mounting recessed luminaires via a mounting ring is described in EP 3 141 799 B1, which is inserted into a recess before the luminaire unit of the recessed luminaire is attached thereto.

[0004] Figure 11 The diagram illustrates a currently known mounting ring and a known mounting system. The mounting ring 1100 thus includes a ring element 1110 comprising a flange portion 1112 configured to interact with the bottom surface of the assembly structure, and two rods 1120 arranged on the ring element 1110. The mounting ring 1100 is thus integrally formed and protrudes from a circular base portion 1111 of the mounting ring 1100. The mounting system 1010 also includes a corresponding latch arm 1200 coupled to a corresponding rod 1120 and thus height-adjustable along the height of the rod 1120, allowing the latch arm to be moved to an operating position in which the latch arm interacts with the top surface and thereby presses the flange portion 1112 of the ring element 1110 against the bottom surface, thereby clamping and securing the mounting ring 1100, and thus clamping and securing the mounting system 1010. Height adjustability is thus achieved via a connecting element 1121 arranged on the outward-facing surface of each rod 1120. Thus, the latch arm 1200 can be operated by the user via the handle 1230 to push the corresponding latch arm 1200 downward toward the ring element 1110, so that the contact portion 1210 of the corresponding latch arm 1200 contacts the top surface of the assembly structure.

[0005] However, the mounting rings and therefore the mounting systems constructed in this way are inflexible in terms of adaptability to a given scenario. Specifically, because the ring element is integrally connected to the rod, known mounting rings are not suitable for different assembly situations, such as where only a very low mounting depth is available, and therefore a short rod is required; or where the assembly structure has a particularly large width, and therefore a long rod is required; and so on. Therefore, by utilizing known mounting rings, and therefore known mounting systems for recessed luminaires, flexible and situation-specific mounting cannot be achieved.

[0006] Therefore, the present invention relates to providing an improved mounting ring, and further to providing a correspondingly improved mounting system, and a correspondingly improved recessed luminaire, the mounting ring having a flexible configuration and adjustability regarding its installation. This task is accomplished respectively by the mounting ring according to independent claim 1, the mounting system according to independent claim 10, and the recessed luminaire according to independent claim 15. The invention is defined by the respective independent claims. Additional features of the invention are provided in the respective dependent claims.

[0007] According to the present invention, a mounting ring for an embedded luminaire is provided. The mounting ring is thus configured to mount a luminaire unit of the embedded luminaire in a recess of an assembly structure having a top surface and a bottom surface. The mounting ring is also configured to be inserted into the recess in a mounting direction, and the mounting ring comprises:

[0008] - A ring element, wherein the ring element includes a flange portion.

[0009] The flange portion is configured to interact with the bottom surface; and

[0010] - At least two rods are arranged on the ring element.

[0011] Thus, each bar is arranged substantially vertically on the ring element, projecting from the ring element at a height substantially parallel to the mounting direction. Each bar is also configured to engage with a latch arm that interacts with the top surface and retains the mounting ring within the recess. Similarly, each bar has a connecting element for engagement with a corresponding latch arm, allowing the corresponding latch arm to be height-adjustably positioned along the height of the corresponding bar. Furthermore, each bar is a separate element attached to the ring element without tools.

[0012] This type of mounting ring design achieves the most flexible and situation-dependent operable mounting ring, allowing recessed luminaires to be flexibly and situation-dependently installed in corresponding recesses. Thus, different specific implementations of the rod can be flexibly attached to the ring element, making various assembly situations manageable. For example, in scenarios where only low installation depths are available, i.e., where the distance between the assembly structure and the underlying surface such as a wall, floor, or ceiling is small, a rod with a corresponding low height can be attached to the ring element. Similarly, in scenarios where the assembly structure has varying widths, requiring the mounting ring to manage different thicknesses, this type of mounting ring easily adapts to corresponding rods of different heights. Furthermore, due to tool-free attachment, the assembly process of the mounting ring is extremely easy and uncomplicated. Therefore, operational flexibility is greatly improved using this provided mounting ring.

[0013] Furthermore, a mounting system for a recessed luminaire is provided. Similarly, the mounting system is used to mount the luminaire unit of the recessed luminaire in a recess of an assembly structure having a top surface and a bottom surface. The mounting system itself is also configured to be mounted in the recess in a mounting direction. Thus, the mounting system includes:

[0014] - A mounting ring according to any exemplary specific embodiment of the mounting ring described or shown herein; and

[0015] - At least two latching arms, wherein each latching arm is arranged on one of the bars of the mounting ring and is movable from the mounting position to the operating position, and each latching arm is movable along the bar height to reach the operating position.

[0016] Thus, at least two rods of the mounting ring allow for height-adjustable positioning of their respective latch arms, wherein the respective latch arms are configured to interact with the top surface in the operating position, thereby clamping the mounting system within the recess, wherein the flange portion of the mounting ring interacts with the bottom surface.

[0017] This type of installation system similarly benefits from the correspondingly constructed mounting ring, as previously mentioned. Therefore, the installation system can operate in a variety of scenarios, thus providing flexibility in system installation.

[0018] Furthermore, a recessed luminaire for mounting within a recess in an assembly structure is proposed. Thus, the assembly structure still has a top surface and a bottom surface, as previously mentioned. Therefore, the recessed luminaire includes:

[0019] - A lighting unit having a housing and a light-emitting element; and

[0020] - An installation system according to any exemplary specific implementation of the installation system described or shown herein, wherein the luminaire unit is coupled to the installation system.

[0021] This type of recessed luminaire benefits from a corresponding mounting system and mounting ring, similar to those previously mentioned. Thus, the recessed luminaire can operate in a variety of scenarios, providing flexibility in both its construction and installation.

[0022] Optionally, the ring element also includes a circular base portion extending substantially parallel to the mounting direction, and a flange portion projecting substantially distally from the circular base portion in a direction substantially perpendicular to the mounting direction, thereby forming a contact surface for interaction with the bottom surface. This construction of the mounting ring is extremely durable and stable, and provides improved stiffness.

[0023] Optionally, each rod is reversibly connected to the base portion. This configuration of the mounting ring further improves its flexibility, operational safety, and sustainability. Maintenance of the mounting ring becomes easier, as only the damaged portion needs replacement; for example, a damaged rod or a rod with worn connecting elements can be easily replaced with a new rod. Furthermore, management of changing scenarios is further simplified, as rods of different heights can be provided, for example, depending on the specific situation. Thus, the reversible connection holds the respective rod with a force equal to or greater than the force applied to the connector via the clamping of the mounting ring within the recess. Specifically, the force acting on the connection between the base portion and each rod during the securing of the mounting ring within the recess—that is, the force acting on the rod in the mounting direction—is less than the force required to connect the respective rod to the ring element, where the latching arm pushes the respective rod away from the top surface of the assembly structure (correspondingly, the annular support element) while the ring element (correspondingly, the flange portion or the enlarged flange portion) contacts the bottom surface of the assembly structure. Therefore, the reversible connection is durable and stable, enabling operational safety of the luminaire.

[0024] Optionally, each rod is connected to the ring element via a connecting mount. The assembly and durability of the mounting ring are further improved by providing specific elements for the separate components used to connect the mounting ring. Thus, the connecting mount can be specifically constructed for a proper mating attachment of the respective rod to the ring element, ensuring maximum rigidity of the connection and preventing play or even wobbling. Preferably, the connecting mount allows for a latching connection. This further simplifies the connection and disconnection of the individual rods from the mounting ring, and thus improves the assembly and maintenance of the mounting ring. More preferably, the connecting mount is arranged on the base portion. This further improves the durability and rigidity of the connection between the rod and the ring element. More preferably, the connecting element of the rod is formed by a height-adjustable latching mechanism. This further improves the operability of the mounting system and thus simplifies the installation of the mounting ring. Simultaneously, the installation of the mounting system is also simplified.

[0025] Optionally, each lever has a retaining mechanism on its top side for holding the corresponding latch arm in the mounting position, wherein preferably, the top side is arranged opposite to the side of the lever connected to the ring element. This configuration of the mounting ring allows for further convenient installation of the system. Thus, the corresponding latch arm can be engaged with the mounting ring in the mounting position, which allows the mounting ring to be installed in a recess.

[0026] Optionally, the retaining mechanism is further configured to enable a folding movement of the respective latch arm from its mounting position to an outward-facing position, in which the respective latch arm can move along the height of the respective bar to its respective operating position. Specifically, each latch arm folds over the top of the respective bar until it is no longer outside the diameter of the ceiling cutout (i.e., the diameter of the recess), but inside the mounting frame or mounting ring. Thus, preferably, the retaining mechanism is configured to enable the folding movement by tilting the latch arm, wherein specifically, the tilt from the mounting position has an angle of approximately 270°, approximately 180°, approximately 160°, or any angle between 160° and 270°. This configuration of the mounting ring and the correspondingly configured mounting system allows for a further convenient installation process. Thus, while the mounting ring is mounted in the recess in the mounting direction, the latch arms are arranged on the mounting ring such that the user only needs to reposition the respective latch arm from its mounting position to the operating position, in which the respective latch arm interacts with the top surface of the assembly structure. In the case of folding movement from the inside / proximal side of the corresponding latch arm to the position (i.e., the mounting position), it is further exemplarily provided that the external dimensions of the mounting system are primarily influenced by the mounting ring. Therefore, the insertion and installation of the mounting ring, and thus the insertion and installation of the mounting system, is particularly simple for the user.

[0027] Optionally, rods of different heights can be connected to the ring element. As previously mentioned, due to the modular arrangement of the mounting ring, where individual rods can be individually connected to the ring element, different configurations of the corresponding rods are also conceivable. Thus, different heights may be required depending on the installation situation. In special cases, it is also conceivable that at least one of at least two rods has a different height from at least one of the remaining rods. This can be useful when the installation depth is uneven, i.e., when the distance from the top surface of the assembly structure to the underlying element (e.g., floor, ceiling, or wall) varies in the mounting area of ​​the respective recessed luminaire, and therefore in the mounting area of ​​the mounting system, and therefore in the mounting area of ​​the mounting ring. Therefore, specifically, rod heights can be in the range of 20 mm to 120 mm, preferably in the range of 25 mm to 100 mm, and more preferably 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 95 mm, 100 mm, 105 mm, and / or 110 mm. These heights allow for different installation depths for mounting rings / mounting systems and recessed luminaires.

[0028] Optionally, each latch arm of the mounting system includes a connecting portion and a contact portion, wherein the connecting portion is the part of the latch arm attached to the corresponding rod, and the contact portion is disposed on the end of the latch arm opposite to the connecting portion, and the contact portion is the part of the corresponding latch arm that interacts with the top surface of the assembly structure. This configuration of the latch arms further facilitates the assembly of the mounting system and its installation in the recess.

[0029] Optionally, each lever has two elongated sides extending along the height of the respective lever, wherein these elongated sides form a guide for guiding the corresponding latch arm. This further simplifies the installation of the mounting system.

[0030] Optionally, each latching arm thus includes a corresponding guide element for guiding movement along the height of the corresponding rod, wherein preferably, the guide element interacts with a guide rail of the corresponding rod. This further simplifies the installation process of the mounting system. Furthermore, this embodiment achieves a synergistic effect between these components.

[0031] Optionally, each lever has an elongated slot extending in a direction parallel to the height of the respective lever, the slot dividing the connecting element of the respective lever, and wherein the slot forms a conduit for a guide pin for the respective latch arm. This further simplifies the installation of the mounting system because the interaction between the respective latch arm and the respective lever is improved.

[0032] Optionally, each latching arm includes a guide pin that interacts with a corresponding rod, and preferably with a corresponding slot in the corresponding rod, wherein the guide pin is also configured to disengage the corresponding latching arm from the connecting element of the corresponding rod upon actuation of the guide pin. This allows for the easiest and most flexible disengagement of the mounting system from the corresponding recess.

[0033] Optionally, the flange portion is equipped with plaster holes. Therefore, the flange portion is formed with a porous surface. This is particularly advantageous if it is desired to plaster the corresponding bottom surface of the assembly structure, such as plastering the corresponding wall, ceiling, or floor. This further improves the connection between the mounting ring and the assembly structure. Furthermore, it improves the aesthetics of the recessed luminaire achieved in this way. Alternatively, the flange portion is formed with a continuous and smooth surface, i.e., a surface without such plaster holes. In this specific embodiment, the smooth lower surface of the flange portion is most aesthetically pleasing when subsequent plastering of the assembly structure is not required, and further surrounds the recess from the bottom side.

[0034] Optionally, the flange portion is coupled to a plate-shaped circular frame element disposed on a surface of the flange portion opposite to the surface facing the bottom surface of the assembly structure, wherein the frame element extends the flange portion and thus forms an enlarged flange portion. With this embodiment, the gap between the mounting ring and the bottom surface of the assembly structure can be closed. This further improves aesthetics. Preferably, the frame element has an outer diameter of approximately 100 mm, 150 mm, or 200 mm, and more preferably, the frame element has an inner diameter substantially corresponding to the inner diameter of the ring element. This allows for the retrofitting of recessed luminaires in a given (too) large recess, wherein the diameter of the recess extends the outer diameter of the flange portion.

[0035] Optionally, the flange portion has a width of approximately 5 mm to 10 mm. This width allows for a stable contact surface with the bottom surface of the assembled structure. Of course, any width in between is conceivable, i.e., approximately 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. Furthermore, this provides an extremely slender, elegant, and practical flange portion.

[0036] Optionally, the mounting ring, and specifically the ring element, and further specifically the flange portion, has an inner diameter in the range of 50 mm to 250 mm, specifically in the range of 50 mm to 100 mm, or 100 mm to 150 mm, or 150 mm to 200 mm, or 200 mm to 250 mm, and preferably in the range of 55 mm to 95 mm, or 105 mm to 145 mm, or 155 mm to 195 mm, or 205 mm to 245 mm; and further preferably, it has a diameter of 50 mm, 55 mm, 60 mm, 65 mm, 90 mm, 95 mm, 100 mm, or 105 mm, or 145 mm, or 150 mm, or 155 mm, or 195 mm, or 200 mm, or 205 mm, or 245 mm, or 250 mm. These configurations of the mounting ring further enhance flexibility because various recess sizes are operable. Therefore, it further improves the flexibility of assembly and installation of recessed lighting fixtures.

[0037] Optionally, the mounting ring is used for installation in a recess in an assembly structure formed by a wall, ceiling, or floor. Therefore, no limitations are given regarding the positioning and orientation of the recessed luminaire. Thus, the luminaire can be a wall-mounted luminaire, a ceiling-mounted luminaire, or a floor-standing luminaire. Therefore, the luminaire can be used in scenarios such as downlights, spotlights, or wall washers.

[0038] Optionally, the recess is circular. This further simplifies the installation of the mounting ring, and thus the installation of the mounting system. In the case where the recess is square, the aforementioned plate-like frame can be used to cover the excess corner portions of the recess. Thus, the frame element can be circular, elliptical, or even rectangular in shape. Preferably, the mounting ring, and therefore the mounting system, has a circular base area.

[0039] Optionally, the mounting ring is made of plastic. This allows for a cost-effective yet still stable, durable, and rigid configuration for the mounting ring and mounting system. Moreover, this implementation reduces the weight of the corresponding mounting ring, mounting system, and therefore the weight of the recessed luminaire.

[0040] Alternatively, the components of the mounting ring can be formed by injection molding. Specifically, the ring element and the rod can be formed by injection molding (in a separate mold, since the rod and ring element are separate parts). This allows for cost and material savings, and further enables the repeatable production of the mounting ring.

[0041] Optionally, the mounting ring also includes a portion of a reversible fastening mechanism configured to interact with a corresponding mating element arranged on the luminaire unit. Thus, preferably, the luminaire unit is connected to the mounting system by means of the reversible fastening mechanism, specifically by means of a bayonet connection. This allows for the easiest and most flexible connection between the luminaire unit of the recessed luminaire and the mounting ring, and therefore with the mounting system, further facilitating the installation of the recessed luminaire.

[0042] Optionally, the connecting element of the rod is configured to position the portion of the corresponding latch arm that interacts with the top surface at a distance spaced from the flange portion along the mounting direction. This allows for different heights of the corresponding latch arms relative to the mounting ring and specifically relative to the flange portion, enabling the handling of different thicknesses / widths of the assembled structure. Since the flange portion and the corresponding portions of the latch arms are interacting elements of the mounting system, involving the clamping and securing of the mounting ring / system within the recess, the distance between these portions along the mounting direction corresponds to the corresponding width of the assembled structure. Therefore, allowing a range to further increase flexibility is further advantageous. Preferably, this distance ranges from approximately 1 mm to 25 mm, or from approximately 1 mm to 40 mm, or from approximately 1 mm to 100 mm, or from approximately 35 mm to 100 mm.

[0043] Optionally, in the mounting position of the latch arm, the diameter of the mounting system at its maximum point is achieved by the flange portion of the ring element of the mounting ring, while in the operating position of the latch arm, the diameter of the mounting system at its maximum point is achieved by the latch arm itself. This allows for extremely simple installation of the mounting system within the recess.

[0044] Optionally, after the mounting system is installed in the recess, the luminaire unit of the recessed luminaire is inserted into the mounting system. Using this method, the mounting ring is first inserted, then the latch arm is positioned in the operating position to secure the mounting system within the recess, and subsequently the luminaire unit is joined to form a complete recessed luminaire, achieving an extremely easy installation process. Thus, before inserting the mounting ring, the appropriate required rod (with its corresponding configuration, specifically in terms of height) can be selected and connected to the ring element. Therefore, a highly flexible recessed luminaire and its corresponding mounting system / mounting ring are provided.

[0066] Figure 1 An embedded luminaire 1 is shown, wherein the luminaire unit 20 is mounted in a mounting ring 100, and correspondingly mounted in a mounting system 10. Figures 2A to 2E Different exemplary embodiments of the mounting system 10 are shown, which further illustrate various exemplary specific embodiments of the rods 120 with respect to their heights h, h1, h2, h3. Thus, each rod 120 is a separate element that is attached without tools to the ring element 110 of the mounting ring 100. Figure 3A and Figure 3B Exemplary installation processes, respectively focusing on the exemplary mounting ring 100 of the exemplary mounting system 10 within the recess 990 of the corresponding assembly structure 900. Figure 4 Further enlarged detail views of the connection between the ring element 110 and the corresponding rod 120 are provided, illustrating an exemplary embodiment of the connecting mount 113. Figures 12A to 12C The connection process for attaching the corresponding rod 120 to the ring element 110 is shown in detail. Furthermore, in... Figure 4 and Figure 12C The mounting ring 100 of the mounting system 10 is shown clamping at the assembly structure 900, illustrating the interaction between the corresponding latch arm 200 connected to the corresponding rod 120 and the top surface 991 of the assembly structure 900 (correspondingly, the annular support element 400 arranged thereon), and the interaction between the flange portion 112 and the bottom surface 992 of the assembly structure 900 (correspondingly, the interaction between the plate-like frame element 300 attached to the flange portion 112 and the bottom surface 992). Thus, the flange element 112, the corresponding plate-like frame element 300, and the latch arm 200, and the latch arm correspondingly coupled to the annular support element 400, perform clamping and fixing of the mounting system 10 within the recess 990.

[0067] also, Figure 4 and Figure 8 An exemplary embodiment of a plate-shaped frame element 300 attached to the lower surface of the flange portion 112 of the mounting ring 100 is shown. Thus, the plate-shaped frame element 300 can be ultrasonically brazed 500 to the flange portion 112, thereby forming an enlarged flange portion 112x. Figure 8 The ultrasonic brazing connection 500 between the flange portion 112 and the frame element 300 is shown in further detail. The frame element 300 is in... Figure 10Shown separately. In the illustrated embodiment, the frame element 300 is circular in shape; however, other shapes, such as elliptical or rectangular, are also conceivable. In the illustrated example, the plate-shaped frame element 300 is attached to the ring element 110 because the recessed lamp 1 will be inserted into the recess 990 of the assembly structure 900, which has a diameter larger than the outer diameter of the flange portion 112. Therefore, the connection between the bottom surface 992 of the assembly structure 900 and the top surface 991 of the flange portion 112 will not be possible along the entire length of the flange portion 112. Depending on the size of the latch arm 200, a mating element is also required on the top surface 991 of the assembly structure 900 to ensure reliable clamping. Therefore, if the latch arm 200 is not long enough to contact the top surface 991, the annular support element 400 can be inserted into the recess 990 and placed on the top surface 991, such that the inner diameter of the contact surface of the corresponding latch arm 200 is reduced, as... Figure 4 as well as Figure 5 , Figure 6A and Figure 6B As shown. Figures 7 to 9 The attachment of the plate-shaped frame element 300 to the flange element 112 is further illustrated.

[0068] Therefore, the illustrated embodiment provides a specific implementation of the mounting system 10, the corresponding mounting ring 100, and thus the recessed luminaire 1, thereby improving its operational flexibility.

[0069] In each exemplary embodiment of the mounting ring 100, respectively in Figures 1 to 9 as well as Figure 12A , Figure 12B and Figure 12C In the mounting system 10, the correspondingly shown rod 120 is a separate element that is attached to the ring element 110 without tools. Furthermore, different further embodiments of the rod 120 and the mounting ring 100 are shown and discussed herein.

[0070] Different specific implementations of the mounting system 10 and mounting ring 100, as well as the recessed luminaire 1, are compatible with each other, but not necessarily combined with each other. However, when combined, they can interact synergistically with each other.

[0071] This application thus focuses on the structure of the mounting system 10, and correspondingly the structure of the mounting ring 100, to improve the insertion and installation of the mounting ring 100 in the recess 990, and correspondingly the insertion and installation of the mounting system 10 in the recess, to further simplify the installation of the corresponding recessed luminaire 1, whose luminaire unit 20 is attached to the corresponding mounting system 10 after it is installed in the recess 990.

[0072] Figure 1The complete setup of an recessed luminaire 1 according to an exemplary embodiment is shown. The luminaire unit 20 is thus attached to a mounting system 10. As shown in other figures, the mounting system 10, and specifically the mounting ring 100, includes a fixing mechanism 117, specifically components of the reversible fixing mechanism 117. In the illustrated exemplary embodiment, the fixing mechanism 117 is implemented via a bayonet connection 117. Thus, the luminaire unit 20 includes corresponding components of the fixing mechanism 117, such as bolts, which are configured to interact with recesses at the inner surface of the mounting ring 100, such as, for example... Figures 2A to 2E , Figure 7 or Figure 9 As shown.

[0073] Mounting ring 100, correspondingly mounting system 10 is inserted into recess 990 in mounting direction D, such as Figure 3A and Figure 3B As specifically shown in the diagram. The luminaire unit 20 is then inserted into the mounting system 10 in the same mounting direction D, wherein the luminaire unit is then secured via the fixing mechanism 117.

[0074] Typically, the mounting system 10 includes a mounting ring 100 (in any embodiment disclosed herein) and a corresponding latching arm 200 that interacts with a lever 120 to clamp the mounting ring 100 (and correspondingly the mounting system 10) within a recess 990. Thus, each latching arm 200 is arranged on one of the levers 120 and is movable from a mounting position M to an operating position O, and each latching arm 200 is movable along heights h, h1, h2, h3 of the lever 120 to reach the operating position O. Therefore, the lever 120 of the mounting ring 100 allows for height-adjustable positioning of its corresponding latching arm 200, wherein the corresponding latching arm 200 is configured to interact with a top surface 991 in the operating position O, thereby clamping the mounting system 10 within the recess 990, wherein a flange portion 112 of the mounting system 10 (or an enlarged flange portion 112x having a frame element 300 attached to the flange portion 112, depending on the scenario) interacts with a bottom surface 992 of the recess 990. The recessed luminaire 1 includes a luminaire unit 20 having a housing and a light-emitting element, and a mounting system 10 (in any of the embodiments disclosed herein) wherein the luminaire unit 20 is coupled to the mounting system 10.

[0075] Mounting ring 100 includes ring element 110 and at least two rods 120 arranged on ring element 110. For example... Figure 2A As shown (and in Figure 6A and Figure 6B In the corresponding right-hand exemplary embodiment, a specific embodiment with three rods 120 is also conceivable. Similarly, and specifically, as the diameter of the recessed luminaire 1 further increases, a specific embodiment with four rods 120, etc., is also conceivable. Figure 1 , Figures 2B to 2E , Figure 3A , Figure 3B , Figure 5 , Figure 6A , Figure 6B , Figure 7 and Figure 9 Other exemplary embodiments shown illustrate a corresponding specific implementation with two rods 120. It is further shown that each rod 120 is attached as a separate element to the ring element 110, and this attachment is performed without tools.

[0076] The ring element 110 thus has a flange portion 112, which is configured to interact with the bottom surface 992, wherein in Figure 1 , Figure 4 , Figure 5 , Figure 6A , Figure 6B , Figure 7 , Figure 8 and Figure 9 In the exemplary embodiment shown, the corresponding mounting ring 100 is designed to be mounted in a recess 990 having a diameter larger than the outer diameter of the flange portion 112, such that in these scenarios, the aforementioned plate-like circular frame element 300 is used to achieve interaction with the bottom surface 992. Therefore, the circular frame element 300 thereby enlarges the flange element 112, resulting in an enlarged flange portion 112x configured to interact with the bottom surface 992.

[0077] Regarding the illustrated embodiment of the mounting ring 100, the ring element 110 may include a circular base portion 111 extending substantially parallel to the mounting direction D. Thereby, a flange portion 112 protrudes substantially distally from the circular base portion 111 in a direction substantially perpendicular to the mounting direction D, and forms a contact surface (upper surface of the flange portion 112) for interacting with the bottom surface 992, or at least forms an attachment surface (lower surface of the flange portion 112) for attaching the previously mentioned frame element 300 thereto to interact with the bottom surface 992.

[0078] Each rod 120 may be arranged substantially vertically on the ring element 110, and protrude substantially parallel from the ring element 110 at heights h, h1, h2, h3 in the mounting direction D. For example, in Figures 2A to 2E As illustrated in various exemplary embodiments, different heights h, h1, h2, h3 of the rod 120 are possible. Although Figures 2A to 2EThe exemplary embodiments shown are intended for use only in exceptional circumstances, but these illustrations are primarily intended to show that the rod 120 can have different heights h, h1, h2, h3. The design of the ring element 110 (on which the rod 120 is mounted as a separate component) makes the mounting ring 100, and therefore the mounting system 10, particularly flexible. This makes it particularly easy to respond to correspondingly limited mounting depths or particularly thick or thin thicknesses w of the assembly structure 900, and to produce and use mounting rings 100 or mounting systems 10 of appropriate design.

[0079] Therefore, rods 120 of different heights h, h1, h2, and h3 can be connected to the ring element 110. Preferably, the heights h, h1, h2, and h3 of the rods 120 are in the range of 20 mm to 120 mm, more preferably in the range of 25 mm to 100 mm, and even more preferably 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 95 mm, 100 mm, 105 mm, or 110 mm.

[0080] An example of the actual use of rods 120 with different heights in mounting ring 100 is a scenario in which the mounting depth of assembly structure 990 (i.e., the distance of assembly structure 990 from the underlying surface) and / or the thickness w of assembly structure 990 itself is not constant, so that different heights h, h1, h2, h3 of rod 120 can be used to respond to this in a particularly flexible and simple manner.

[0081] As shown, each lever 120 is configured to engage with a latch arm 200, which interacts with the top surface 991 and retains the mounting ring 100 within the recess 990. In embodiments where the recessed luminaire 1 is inserted into an excessively large recess 990, i.e., the diameter of the recess extends the outer diameter of the flange portion 112, it is typically necessary to extend the top surface 991 via a corresponding annular support element 400 of the mounting system 10, as previously mentioned. In embodiments where the corresponding latch arm 200 is long enough to reach the top surface 991, the addition of the corresponding annular support element 400 may not be necessary even in the corresponding scenario where the outer diameter of the flange portion 112 is smaller than the diameter of the recess 990.

[0082] Furthermore, as shown in the exemplary embodiment, each lever 120 may have a connecting element 121 for engagement with a corresponding associated latching arm 200. Thus, the connecting element 121 allows the corresponding latching arm 200 to be height-adjustably positioned along the heights h, h1, h2, h3 of the corresponding lever 120. Specifically, the connecting element 121 of the corresponding lever 120 may be formed by a height-adjustable latching mechanism, as in... Figure 4 The enlarged diagram provides a more detailed example.

[0083] In the exemplary embodiment shown, each rod 120 has two elongated sides extending along the height h, h1, h2, h3 of the respective rod 120, wherein these elongated sides form guide rails 129 for guiding the respective latch arm 200.

[0084] As also exemplarily shown, each rod 120 may have an elongated slot 123 extending in a direction parallel to the height h, h1, h2, h3 of the respective rod 120, wherein the elongated slot 123 may separate the connecting element 121 of the respective rod 120, and thereby form a conduit for the guide pin 240 of the respective latch arm 200.

[0085] In view of the accompanying drawings, but specifically in view of Figure 4 It is evident that, in the exemplary embodiment shown, each latch arm 200 may include a connecting portion 220 and a contact portion 210, wherein the connecting portion 220 is the portion of the latch arm 200 attached to the corresponding rod 120, and the contact portion 210 is disposed on the end of the latch arm 200 opposite to the connecting portion 220, and the contact portion 210 is the portion of the corresponding latch arm 200 that interacts with the top surface 991 of the assembly structure 900 (or, in the corresponding scenario, at least with the aforementioned annular support element 400).

[0086] like Figure 4 As shown in the enlarged view, the contact portion 210 may be provided with a gripping surface 211, which provides special holding of the mounting system 10 on the top surface 991 and correspondingly on the support element 400.

[0087] Given Figure 3A , Figure 3B and Figure 4It is evident that the connecting element 121 of the lever 120 can be configured to position the portion of the corresponding latch arm 200 that interacts with the top surface 991 (or the corresponding support element 400) at a distance spaced from the flange portion 112 along the mounting direction D. Specifically, the connecting element 121 thereby allows the corresponding latch arm 200 to latch in a corresponding position where the contact portion 210 of the corresponding latch arm 200 contacts the top surface 992 (or at least the support element 400 arranged on the top surface 992). Thus, the distance between the portion of the corresponding latch arm 200 that interacts with the top surface 991 (or the corresponding support element 400) (i.e., the contact portion 210) and the flange portion 112 substantially corresponds to the width w of the corresponding assembly structure 900. Therefore, different levers 120 (specifically, with respect to their different heights h, h1, h2, h3) allow for different widths w of the assembly structure 900. Specifically, it may be desirable to be able to handle a certain range of distances (achieving clamping on different assembly structures 900 with corresponding widths w, and thus providing adaptability in terms of the width range w of the assembly structure 900). Therefore, this distance (correspondingly, the width w) is preferably a range from approximately 1 mm to 25 mm, or from approximately 1 mm to 40 mm, or from approximately 1 mm to 100 mm, or from approximately 35 mm to 100 mm (correspondingly, the width range w). This distance further relates to the corresponding set height of the corresponding rod 120 for engagement with the corresponding latch arm 200, and the difference between the possible range of set heights of the corresponding rod 120 and the height of the corresponding latch arm 200 corresponds to the width w of the corresponding assembly structure 900, such as... Figure 4 As shown. Therefore, it is also conceivable that the corresponding range for setting the height could be from 1 mm to 25 mm, or from 1 mm to 40 mm, or from 35 mm to 100 mm, etc.

[0088] In addition, each latch arm 200 may also include a corresponding guide element 230 for guiding movement along the heights h, h1, h2, h3 of the corresponding rod 120, wherein preferably, the guide element 230 interacts with the guide rail 129 of the corresponding rod 120.

[0089] An exemplary configuration of a latch arm 200 is also shown in an exemplary embodiment, the latch arm including a guide pin 240 that interacts with the corresponding rod 120 and preferably with the corresponding slot 123 of the corresponding rod 120. Thus, the guide pin 240 can also be configured not only to guide movement of the latch arm 200 in a direction parallel to (or opposite to) the mounting direction D, but also to disengage the corresponding latch arm 200 from the connecting element 121 of the corresponding rod 120 upon actuation of the guide pin 240. Therefore, the previously configured positioning of the corresponding latch arm 200 can be readjusted by further moving the latch arm 200 toward the top surface 991 (or toward the aforementioned annular support element 400 in the respective scenario) or by moving the latch arm 200 in the mounting direction D (i.e., upward) to release the previously performed clamping of the mounting ring 100 of the corresponding mounting system 10.

[0090] The position of the latch arm 200 that contacts the top surface 991 (correspondingly, the support element 400) and thereby clamps the corresponding mounting ring 100 of the mounting system 10 in the recess 990 is also referred to as the operating position O of the corresponding latch arm 200. This is in Figure 3B This is specifically shown in the text.

[0091] The mounting position M of the corresponding latch arm 200 (e.g.) Figure 3A (Exemplary example shown) is the position of the latch arm 200, at which the mounting system 10 can be mounted within the recess 990. Figure 3A As exemplarily illustrated, this can be achieved via a rearward folding of the corresponding latch arm 200 in the proximal direction (i.e., toward the mounting ring 100, and correspondingly the center of the mounting system 10). Using this exemplary embodiment, the mounting system 10 can be further and more easily inserted into the corresponding recess 990 without colliding with the corresponding edge of the assembly structure 900, which could potentially prevent insertion of the mounting system 10. Therefore, in the mounting position M of the latch arm 200, the external dimensions of the corresponding mounting system 10 can be primarily influenced by the mounting ring 100, further simplifying insertion.

[0092] In this respect, each of the illustrated levers 120 has a retaining mechanism on its top side 122. The retaining mechanism is used to hold the respective latching arm 200 in its respective mounting position M, wherein the top side 122 is arranged opposite to the side of the lever 120 connected to the ring element 110. Thus, in the respective mounting position M of the latching arm 200, the diameter of the mounting system 10 at its maximum point can be achieved by the flange portion 112 (which, depending on the scenario, is formed by the plate-shaped circular frame element 300 attached to the flange portion, creating an enlarged flange portion 112x). In the operating position O of the latching arm 200, the diameter of the mounting system 10 at its maximum point can be achieved by the latching arm 200, at least as long as the frame element 300 and the annular support element 400 are not required, since these (as shown in the respective figures) further extend the diameter of the mounting ring 100 and the mounting system 10.

[0093] like Figure 3A and Figure 3B As specifically shown in its summary, the retaining mechanism can also be configured to allow the corresponding latch arm 200 to fold from its mounting position M to an outward-facing position, in which the corresponding latch arm 200 is movable along the heights h, h1, h2, h3 of the corresponding rod 120. Thus, as the corresponding latch arm 200 moves along the heights h, h1, h2, h3 of the corresponding rod 120 (i.e., in a direction substantially opposite to the mounting direction D), the latch arm 200 is brought into its corresponding operating position O, in which the latch arm interacts with the top surface 991 (or with the support element 400 interacting with the top surface 991). As exemplarily shown, the retaining mechanism can be configured to achieve folding movement by tilting the latch arm 200. Different tilt angles are thus conceivable, wherein specifically, the tilt from the mounting position M can have an angle of approximately 270°, approximately 180°, approximately 160°, or any angle between 160° and 270°. Figure 3A and Figure 3B As shown, the tilt angle implemented in the illustrated exemplary embodiment is approximately 180°.

[0094] Figure 5 An exemplary embodiment of the mounting system 10 is shown, wherein the mounting system 10 is inserted into a recess 990 that requires the use of the support element 400 because the diameter of the recess is too large for the mounting ring 100 and therefore the mounting system 10. Specifically, this is illustrated in scenarios where older recessed luminaires are replaced by modern recessed luminaires that require particularly little space. In these scenarios, the support element 400 and the frame element 300 allow for the mating installation of such modern recessed luminaires 1 because the excessive clearance of the recess 990 is bridged via the support element 400 on the top surface side and via the frame element 300 on the bottom surface side. This also improves the aesthetics of the recessed luminaire 1.

[0095] Specifically, such as Figure 4 As shown, each rod 120 can be reversibly coupled to the base portion 111, and as illustrated, the rod 120 can be coupled to the ring element 110 via a corresponding coupling mount 113, which, in the presented exemplary embodiment, is positioned on the base portion 111. The coupling mount 113 allows for a particularly simple and direct connection between the corresponding rod 120 and the ring element 110, and further enhances the structural rigidity of the mounting ring 100. Thus, the rod 120 includes a corresponding engaging element 124 at its lower end portion for coupling with the ring element 110. These engaging elements 124 thus interact with the coupling mount 113 for a durable and rigid connection. The rod 120 can be inserted into the corresponding coupling mount 113 with the engaging element 124 in front, and furthermore, the engaging element 124 can preferably interact with the ring element 110 in a latching manner (e.g., via a snap-fit ​​engagement), and thus secure the rod 120. Figure 4 As can be seen, the coupling mount 113 specifically allows for a latching connection between the corresponding rod 120 and the ring element 110, which creates a particularly rigid and stable connection, but is also preferably reversible. The coupling mount 113 may also include an actuator for disengaging the corresponding connecting rod 120 from the ring element 110.

[0096] Figure 12A , Figure 12B and Figure 12C An exemplary embodiment of the connection process between a corresponding exemplary embodiment of the rod 120 and a corresponding exemplary embodiment of the ring element 110 of the mounting ring 100 is shown. Thus, it is shown that the rod 120 can be mounted from the bottom side of the mounting ring 100 (wherein the bottom side is the side of the mounting ring 100, the corresponding mounting system 10, and the corresponding luminaire 1 that is visible to the user when mounted in the recess 990). The connecting mount 113 can be formed as a conduit with a locking element. Thus, the rod 120 first enters the connecting mount 113 of the ring element 110 with its top side 122, as... Figure 12A As shown, the entire rod 120 then passes through the connecting mount 113, as... Figure 12B As shown. The connection process is completed when the connecting element 124 of the rod 120 reaches the bottom side of the connecting mount 113 and interlocks with the corresponding element of the connecting mount 113, as indicated. Figure 12CAs shown. Then, through this connection process and the interaction of the connecting element 124 and the connecting mount, the rod 120 is securely attached to the ring element 110. This is applicable to various specific embodiments of the rod 120 with different heights h, h1, h2, h3. As further exemplarily shown, the connecting mount 113 may have a release element to release the connection between the rod 120 and the ring element 110, making the connection reversible. A guide rail 129 formed by the elongated side of the respective rod 120 can further facilitate the installation process of the respective rod 120. To remove a previously installed rod 120, the aforementioned steps are performed in reverse, causing the rod 120 to move in a downward direction.

[0097] The number of connecting mounting pieces 113 can be selected depending on the size of the mounting ring 100. For example... Figure 6A and Figure 6B as well as Figures 2A to 2E As exemplified in the summary, the larger mounting ring 100 is equipped with a larger number of rods 120, and therefore can be equipped with a larger number of connecting mounts 113. However, it is also conceivable that if a particular heavy-duty lighting unit 20 (e.g., due to a heavy heat sink or other electronic equipment) will be inserted into the corresponding mounting ring 100, the smaller mounting ring 100 will be equipped with a greater number of rods 120 (and therefore possibly a greater number of connecting mounts 113), and vice versa. Similarly, the corresponding rods can be selected according to the corresponding possible range of heights h, h1, h2, h3 of the corresponding rods 120 and the set height of the connection between the corresponding rod and the corresponding latch arm 200. Therefore, the selection of the configuration of the corresponding mounting ring 100 is possible.

[0098] For example Figure 4 and Figure 8 As exemplarily illustrated, frame element 300 may provide additional contact surfaces for interacting with the lower surface of the corresponding rod 120, thereby further enhancing the stability and rigidity of the connection between rod 120 and ring element 110. Therefore, the coupling element 124 of rod 120 may be provided with certain contact elements to provide not only a rigid connection with ring element 110, but also further interaction with frame element 300.

[0099] As further illustrated in the various figures, the flange portion 112 can be obtained in different configurations. Thus, the flange portion 112 can be equipped with a hole 119 and therefore have a porous surface 112b, or alternatively, it can be provided with a continuous and smooth surface 112a. While a smooth surface 112a is preferred in scenarios where the flange portion 112 is visible to the user, a porous surface 112b is preferred in scenarios where plastering of the assembly structure 900 (specifically, the bottom side 992 of the assembly structure 900) is required after the installation of the mounting system 10 (correspondingly the recessed luminaire 1). Therefore, the hole 119 can be a plastering hole 119.

[0100] Both configurations of the surface of the flange portion 112 are suitable for attaching corresponding plate-shaped circular frame elements 300. The connection between these components can thus be performed via adhesive bonding, brazing, welding, or preferably ultrasonic brazing 500. Therefore, the specific implementation of the connection depends on the respective materials of the components. Since the components are preferably made of plastic, ultrasonic brazing 500 provides the most durable and rigid connection.

[0101] Therefore, as Figure 1 , Figure 4 , Figure 5 , Figure 6A , Figure 7 , Figure 8 and Figure 9 As exemplified in the example, the frame element 300 is preferably mounted on the flange portion 112 having a porous structure 112b. This further enhances the durability of the connection. Figure 4 and Figure 8 As shown, this specifically applies to the ultrasonic brazing connection 500, because the hole 119 thereby provides a further beneficial connection between the flange portion 112 and the frame element 300. Therefore, in the preferred embodiment where the frame element 300 is joined to the flange portion 112 via ultrasonic brazing 500, a porous surface 112b is present.

[0102] The mounting ring 100 of this configuration (whose flange portion 112 is connected to a plate-shaped circular frame element 300, which is arranged on the surface of the flange portion 112 opposite to the surface facing the bottom surface 992 of the assembly structure 900) therefore includes an enlarged flange portion 112x, in which the frame element 300 extends the flange portion 112. Thus, the frame element 300 then extends the flange portion 112 distally, and thereby forms a contact surface for interacting with the bottom surface 992.

[0103] like Figure 6A and Figure 6B As exemplified in the example, frame element 300 can be obtained in different sizes, wherein the size differs with respect to its diameters d, d1, d2, d3. Thus, it is conceivable that frame element 300 may have an outer diameter d, d1, d2, d3 of approximately 100 mm (e.g., diameter d1), or an outer diameter of 150 mm (e.g., diameter d2), or an outer diameter of 200 mm (e.g., diameter d3). More preferably, frame element 300 has an inner diameter that substantially corresponds to the inner diameter of ring element 110. The diameters d, d1, d2, d3 of frame element 300 can thus substantially correspond to the corresponding diameters d, d1, d2, d3 of support element 400, as well as... Figure 4 , Figure 5 , Figure 6A and Figure 6B This is exemplified by way of example. While the frame element 300 is necessary when the recess 990 is larger than the outer diameter of the flange portion 112, since clamping at the bottom surface 992 would otherwise be impossible, the necessity of the support element 400 is not always apparent. Specifically, the necessity of the support element 400 depends on the configuration of the corresponding latch arm 200. Thus, it is conceivable that a specific implementation in which the latch arm 200 is long enough to reach the top surface 991 of the recess structure 900 is conceivable. However, in scenarios where the latch arm 200 is not long enough, the support element 400 is required to ensure proper clamping of the mounting system 10, and correspondingly the mounting ring 100, and thus to ensure proper clamping of the recessed luminaire 1 within the recess 990.

[0104] The flange portion 112 may have a width of approximately 5 mm to 10 mm, which is sufficient to provide a stable clamping contact with the bottom surface 992 and is also aesthetically pleasing to the user. Similarly, this width provides sufficient surface for attachment to the corresponding frame element 300.

[0105] The inner portion of the mounting ring 100 (and correspondingly the mounting system 10) is used to accommodate the luminaire unit 20 to form a recessed luminaire 1. Thus, the inner diameter of the mounting ring 100, and specifically the inner diameter of the ring element 110, and even more specifically the inner diameter of the flange portion 112, is adapted to the common diameter of such luminaire units 20. Specifically, the corresponding inner diameter can be approximately in the range of 50 mm to 250 mm, specifically in the range of 50 mm to 100 mm, or 100 mm to 150 mm, or 150 mm to 200 mm, or 200 mm to 250 mm, and preferably in the range of 55 mm to 95 mm, or 105 mm to 145 mm, or 155 mm to 195 mm, or 205 mm to 245 mm; and more preferably, the diameter is 50 mm, 55 mm, 60 mm, 65 mm, 90 mm, 95 mm, 100 mm, or 105 mm, or 145 mm, or 150 mm, or 155 mm, or 195 mm, or 200 mm, or 205 mm, or 245 mm, or 250 mm.

[0106] Figure 10 A plate-shaped circular frame element 300 is shown, which may be attached to the flange portion 112 of the mounting ring 100, depending on the specific scenario. Thus, the frame element 300 may include a plurality of connecting portions 310 arranged proximal to the surface of the frame element 300 facing the ring element 110, wherein these connecting portions 310 are positioned near the flange portion 112. Specifically, six connecting portions 310 are provided, with small gaps between them. This is... Figure 4 , Figure 7 and Figure 8 This is specifically illustrated. Preferably, if such connection portions 310 are present, these connection portions are used for an ultrasonic brazing connection 500 between the flange portion 112 and the frame element 300. This provides a further stable and rigid connection. The ultrasonic brazing 500 is... Figure 7 , Figure 8 and Figure 9 The combined view is shown exemplarily, illustrating the attachment of the frame element 300 to the flange portion 112, thereby magnifying the flange portion 112x.

[0107] Furthermore, the frame element 300 may be provided with a protruding edge 320, which is positioned distally and thus on the outer edge of the frame element 300. Specifically, the protruding edge 320 may form the outer surface of the frame element 300, which defines the outer diameter of the frame element 300. Thus, the edge 320 (preferably slightly) protrudes toward the corresponding bottom surface 992 in the mounting direction D, such that when the mounting ring 100 or the corresponding mounting system 10 is mounted in the recess 990, the protruding edge 320 contacts the assembly structure 900. Therefore, this can enclose the bottom side of the recessed luminaire 1, the corresponding mounting system 10, and the corresponding mounting ring 100 toward the assembly structure 900.

[0108] As further shown in the various figures, the frame element 300 may also be provided with a bracket 330 extending radially from its proximal region toward its distal region. Specifically, the bracket 330 may extend from the connecting portion 310 to the protruding edge 320. Thus, the bracket 330 provides additional stiffness to the frame element 300, and furthermore, their upper surfaces (facing the recess 990 and the bottom surface 992, respectively) provide additional contact surfaces for the frame element 300 toward the bottom surface 992, and preferably, when the mounting ring 100, and correspondingly the mounting system 10, is mounted in the recess 990, the bracket 330 is at least partially in contact with the bottom surface 992.

[0109] In the illustrated embodiment, the frame element 300 is circular and therefore annular; however, other frame shapes, such as rectangular, elliptical, etc., are also conceivable. Thus, the shape of the frame element 300 can be adapted to the shape of the corresponding recess 990.

[0110] For details regarding the ring support element 400, please refer to [link / reference]. Figure 4 , Figure 5 , Figure 6A and Figure 6BAs previously mentioned, scenarios requiring an annular support element 400 are conceivable. This support element 400 thus forms part of the mounting system 10. The annular support element 400 is then positioned on the top surface 991 of the assembly structure 900 of the recess 990 to expand the corresponding contact surface of the respective latching arm 200. Thus, the respective latching arm 200 is configured to interact with the annular support element 400 in the operating position O, thereby clamping the mounting system 10 within the recess 990, where the frame element 300 of the mounting ring 100 interacts with the bottom surface 992. Furthermore, the annular support element 400 has an outer diameter larger than that of the recess 990 and an inner diameter smaller than that of the recess 990, thereby providing a support surface for interaction with the respective latching arm 200. The inner diameter can be configured to allow insertion of the mounting ring 100, and correspondingly its rod 120, in the mounting position in the mounting direction D, where the latching arm 200 is preferably attached to the rod.

[0111] Therefore, the outer diameters d, d1, d2, and d3 of the annular support element 400 can approximately correspond to the outer diameters d, d1, d2, and d3 of the frame element 300, as previously mentioned. Furthermore, the inner diameter of the annular support element 400 can approximately correspond to the inner diameter of the frame element 300.

[0112] like Figure 5 , Figure 6A and Figure 6B As further exemplarily depicted, the annular support element 400 may include a hinge portion 410 that allows the annular support element 400 to fold into a folded shape during mounting in the recess 990. Thus, the support element 400 can be folded compactly so that it can be inserted into the recess 990. Since the support element 400 is larger than the recess 990 in the unfolded configuration, this embodiment provides simple configuration possibilities. The hinge portion 410 may be implemented via material weakening (e.g., through a corresponding notch), or alternatively via additional elements connecting the respective two-part support elements 400.

[0113] As previously mentioned regarding the interaction between the latch arm 200 and the top surface 991, it is also conceivable that the lever 120 is configured to position the portion of the corresponding latch arm 200 that interacts with the annular support element 400 (i.e., the contact portion 210) at a distance spaced from the frame element 300 along the mounting direction D. This distance substantially corresponds to the width w of the assembly structure 900, and in this scenario, the width of the support element 400 is also taken into consideration. Preferably, this distance is in the range of approximately 1 mm to 25 mm, or approximately 1 mm to 40 mm, or approximately 1 mm to 100 mm, or approximately 35 mm to 100 mm.

[0114] Furthermore, it may be desirable that the annular support element 400 is centrally positioned in the recess 990, such that the mounting system 10 is then similarly centrally arranged in the recess 990.

[0115] The components of mounting ring 100, and corresponding mounting system 10, can be manufactured by injection molding. This is particularly applicable to ring element 110 and corresponding rod 120.

[0116] The recess 990 can be circular, but of course it can also be other shapes. Depending on the size of the recess 990, the mounting ring 100, the mounting system 10, and the recessed luminaire 1 can be implemented individually or in combination for the application.

[0117] As previously mentioned, the assembly structure 900 can form the walls, floors, or ceilings of a corresponding environment or room, and the assembly structure 900 has a corresponding recess 990 with a specific diameter. An improved insertion and installation in the corresponding recess is provided through the specific implementation of the presented recessed luminaire 1, mounting system 10, and mounting ring 100. Thus, different application scenarios for this type of recessed luminaire 1 (and therefore, similarly for the mounting ring 100 and mounting system 10) are conceivable. Furthermore, in the specific scenario where the recessed luminaire 1 operates as a wall washer, downlights, spotlights, etc., are possible.
