Description

Technical Field

[0001] This utility model belongs to the field of LED lighting technology, specifically, it relates to a modularly designed LED wall washer light device. Background Technology

[0002] Among existing high-power recessed spotlights, those used to achieve wall-washing effects generally suffer from design and functional limitations. Firstly, most fixtures adopt an integrated structural design, with the wall-washing angle determined by the fixed structure at the factory. If the wall-washing angle needs to be adjusted to suit different scenarios (such as changes in wall height or decorative style), the entire fixture must be replaced. It is not possible to make local adjustments only to meet the angle adjustment needs, resulting in poor flexibility and increased equipment replacement costs.

[0003] Secondly, while some luminaires employ a "lens + reflector" combination to attempt to optimize wall washing effects, the manufacturing process of the reflector has significant shortcomings. Limited by a single spinning or stamping process, the shape design of the reflector is relatively simple, mostly limited to structural processing around a coaxial direction. It cannot achieve the design and manufacturing of eccentric structures or other complex contours, making it difficult to adjust the light path through structural optimization of the reflector itself. Furthermore, the single-process design makes it difficult for the reflector to balance "connection stability" and "shape complexity"—if emphasis is placed on the toughness of the connection to prevent breakage during installation or use, complex shapes cannot be achieved; if a simple shape is pursued to fit the process, the connection points are prone to damage due to insufficient toughness.

[0004] Third, the wall-washing effect of existing wall washer lights mainly relies on the optical design of the internal lens. The reflector cup only plays an auxiliary role in focusing the light and cannot substantially change the light path through its own structure. This results in a single dimension of wall-washing effect adjustment, making it difficult to meet the diverse needs of different scenarios for light spot width, uniformity, and illumination angle.

[0005] Furthermore, due to the limitations of the integrated design and reflector function, existing luminaires require the entire lamp to be discarded and replaced even if only the wall washing angle does not meet the requirements or the reflector is damaged during maintenance. This not only significantly increases maintenance costs but also wastes resources of undamaged components (such as lamp holders and power modules), failing to meet the requirements for energy conservation and consumption reduction. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a modularly designed LED wall washer light device.

[0007] The reflector cup assembly can be replaced and maintained independently without discarding the lamp head module. Operations can be performed only on the damaged or adjustable reflector cup parts, which greatly reduces user maintenance costs and the resource consumption caused by replacing the entire lamp. This is an important practical value derived from the core innovative function of the device, and effectively improves the product's economic efficiency.

[0008] "Separate connection" refers to the reflector cup connecting bracket and cup body being a detachable assembly structure. The two are not integrally formed and can be disassembled or fixedly assembled through a preset connection structure.

[0009] To achieve the aforementioned objectives, the technical solution adopted by this utility model includes: Lamp head module and reflector cup assembly; the lamp head module includes a module body and at least one reflector cup connector, the reflector cup connector being connected to the module body; the reflector cup assembly includes a reflector cup connecting bracket and a cup body, the reflector cup connecting bracket being detachably connected to the reflector cup connector, and the reflector cup connecting bracket being separately connected to the cup body; It should be noted that the cup body is equipped with multiple curved contour structures for changing the light emission path, and these multiple curved contour structures are arranged sequentially along the light emission direction of the cup body. Specifically, the multiple curved contour structures are made by sequentially arranging and combining multiple cup body sidewalls with different curvatures. Furthermore, the multiple curved contour structures are arranged sequentially along the axial direction of the cup body (i.e., the light emission direction from the lamp head module to the light emission port of the cup body), and the light is "gradually refracted and reflected" through different curved contours to achieve a step-by-step adjustment of the light emission angle; secondly, they are respectively set in different circumferential or radial areas of the cup body sidewalls to perform differentiated reflection of incident light from different directions of the cup body, and collaboratively optimize the width and uniformity of the wall washing light spot, ultimately achieving a precise change in the light emission path.

[0010] This invention achieves two key improvements: First, by detachably connecting the lamp head module and the reflector cup assembly, it overcomes the limitations of traditional integrated lamps that require fixed angles and replacement of the entire lamp, enabling modular platform expansion by allowing for adjustment of the wall-washing angle through the selection of different reflector cup accessories. Second, by separating the reflector cup connecting bracket from the cup body and employing multiple curved contour structures within the cup body, it solves the problem of traditional reflector cups having "single spinning / stamping processes that cannot balance connection stability and complex shape processing," while ensuring product installation reliability and the feasibility of processing complex reflector cup shapes, thus providing a structural foundation for optimizing wall-washing effects.

[0011] Preferably, the reflective cup connecting bracket is provided with a connecting part for cooperating with the reflective cup connector, and the cup body has multiple arc contour structures integrally formed.

[0012] In this utility model, by defining the "connecting part of the reflector cup connecting bracket" and the "integrated molding of multiple arc contour structures of the cup body", the process adaptation logic is further clarified: the connecting part can be adapted to tough processes such as aluminum plate spinning to ensure the fracture resistance when connected with the lamp head module; the integrated molding of the cup body is adapted to complex shaping processes such as die casting to ensure the processing accuracy of multiple arc contours and strengthen the dual guarantee effect of "separate design" on "connection toughness" and "complex shape".

[0013] Preferably, a docking post is fixedly connected to the reflector cup connector, and a right-angle groove adapted to the docking post is provided in the reflector cup connecting bracket, and the docking post is engaged with the right-angle groove.

[0014] In this utility model, the specific structure of "connecting post and right angle slot" realizes the "detachable connection" into an operable quick disassembly and assembly solution: no complicated tools are required, and the connection / disassembly of the reflector cup assembly and the lamp head module can be completed by "insertion-rotation", which greatly improves the convenience of replacing reflector cup accessories and further supports the core function of "module platform expansion".

[0015] Preferably, the reflective cup connecting bracket is provided with a skirt component, which is sleeved with the cup body; a fixing screw is threadedly connected to the skirt component, and a threaded fixing hole adapted to the fixing screw is opened in the cup body, and the skirt component is connected to the cup body through the fixing screw.

[0016] In this utility model, the stability of the "separate connection between the reflector cup connecting bracket and the cup body" is enhanced by "skirt component sleeve + two threaded connection of fixing screws": the skirt component increases the contact area between the two, and the two fixing screws achieve rigid fastening, avoiding loosening of the connection due to vibration during long-term use, ensuring the stability of the wall washing angle, and improving the overall service life of the device.

[0017] Preferably, the skirt component has a positioning notch, and the cup body has a positioning boss that matches the positioning notch, and the positioning boss is inserted into the positioning notch.

[0018] In this invention, the "positioning notch and positioning boss insertion" provides a precise positioning reference for the assembly of the reflector cup connecting bracket and the cup body: avoiding circumferential misalignment during assembly, ensuring that the multi-arc contour of the cup body is precisely matched with the light output direction of the lamp head module, and preventing deviations in the wall washing effect caused by misalignment, such as uneven light spots and angle shifts.

[0019] Preferably, the cup body is provided with a fixed boss, and the fixed boss is provided with at least two positioning protrusions; the reflective cup assembly also includes a spring assembly, the spring assembly cooperates with the fixed boss, and the positioning protrusions are used to limit the lower edge of the spring assembly from warping; the fixed boss is also provided with a threaded hole.

[0020] In this utility model, the problem of spring assembly displacement after installation is solved by "fixed boss + positioning protrusion + spring assembly cooperation": the positioning protrusion can effectively limit the lower edge of the spring assembly from tilting up, and avoid the spring from affecting the stability of the ceiling installation due to displacement; at the same time, the threaded hole of the fixed boss provides a reliable connection base for the spring assembly, further ensuring the structural stability of the device after installation.

[0021] Preferably, the reflector cup connector is internally threaded with a fixing screw, and the module body has a threaded blind hole that matches the fixing screw. The fixing screw is screwed into the threaded blind hole to fix the reflector cup connector and the module body. The bottom of the module body is provided with an optical kit.

[0022] In this invention, the stability of the reflector cup connector and the module body is ensured by "fixing screws and threaded connection", avoiding the displacement of the reflector cup assembly caused by loose connection; by "covering the bottom of the module body with an optical kit", the light output path of the lamp head module is optimized, so that the light enters the multi-arc contour of the cup body more accurately, further improving the uniformity of the wall washing effect.

[0023] Preferably, the reflector cup assembly further includes sealing foam, which is fixedly connected to the end of the cup body away from the lamp head module; The spring assembly includes a connecting frame, a spring body, and a ceiling mounting bracket. One side of the connecting frame has a folded edge plate, which is fixedly connected to the cup body. A rotating shaft is fixedly connected to the top of the connecting frame. The spring body is sleeved on the rotating shaft. The ceiling mounting bracket is rotatably connected to the rotating shaft, and both ends of the spring body are fixedly connected to the ceiling mounting bracket. The ceiling mounting bracket has mounting holes, into which fixing screws are inserted. The connecting frame is screwed into the cup body and fixed thereto by the fixing screws. The fixing screws pass through the mounting holes and are screwed into the threaded holes of the fixing boss to fix the connecting frame and the cup body.

[0024] In this invention, the "cup end fixed sealing foam" achieves gap sealing and buffering when the device is installed with the ceiling; the "spring assembly rotation shaft + ceiling mounting bracket" structure allows the ceiling mounting bracket to rotate flexibly to adapt to different ceiling installation angles, improving the adaptability of the device installation, while the spring body provides elastic support to ensure the stability after installation.

[0025] Compared with the prior art, the advantages of this utility model include: (1) The modular LED wall washer light device provided by this utility model has a core structure of “detachable connection between lamp head module and reflector cup assembly”. Without replacing the whole lamp, the wall washer angle can be quickly adjusted by selecting different specifications of reflector cup assembly to meet the needs of diverse usage scenarios. (2) This utility model provides a modular LED wall washer device with a "separate connection between the reflector cup connecting bracket and the cup body," which allows both to be adapted to different processes: the reflector cup connecting bracket can be matched with a tough process to ensure the fracture resistance when connected to the lamp head module; the cup body can be matched with complex shaping processes such as die casting to achieve the processing of "multiple arc contour structures." This design not only meets the dual requirements of "connection position toughness" and "complex shape of the main body," but also provides a structural foundation for optimizing the wall washer effect, which is the key to the implementation of the device's core function. (3) The present invention provides a modular LED wall washer device with a cup body having a variety of arc contour structures for changing the light output path. The light output path of the lamp head module can be directly adjusted through contour reflection. It can achieve diversified and high-precision wall washer effects such as light spot width and uniformity adjustment without excessive reliance on internal lenses. It simplifies the internal optical design of the lamp and improves the controllability of the wall washer effect. It is the direct functional carrier for the device to achieve "wall washer effect optimization". Attached Figure Description

Unless otherwise specified, the dimensions, materials, and manufacturing processes of each component in the modular LED wall washer light device of this utility model embodiment can be selected according to specific circumstances, and no special limitations or explanations are made here.

[0035] Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0036] Example 1

[0037] Please see Figure 1 and Figure 2 This embodiment discloses a modularly designed LED wall washer light device, including a lamp head module 1.

[0038] Furthermore, the lamp head module 1 includes a module body 11, a reflector cup connector 12 is connected to the bottom of the module body 11, a fixing screw 13 is internally threaded to the reflector cup connector 12, a threaded blind hole adapted to the fixing screw 13 is opened in the module body 11, and an optical kit 14 is provided at the bottom of the module body 11.

[0039] It is understood that the specific structure of the optical kit 14 is the same as that of the existing LED wall washer lamps, and will not be described in detail here. The core function of the optical kit 14 in this embodiment is to perform preliminary light uniformity and direction correction on the light emitted by the lamp head module 1, so that the light enters the cup body 23 at a more uniform angle. It works in conjunction with the various arc contour structures of the cup body 23 to further improve the uniformity and angle controllability of the wall washer light spot through the combination of preliminary correction and precise reflection.

[0040] Specifically, a docking post 15 is fixedly connected to one side of the reflector cup connector 12, and there are two reflector cup connectors 12 in total.

[0041] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 This embodiment discloses a modularly designed LED wall washer light fixture, including a reflector cup assembly 2.

[0042] Furthermore, the reflective cup assembly 2 includes a reflective cup connecting bracket 21, a second fixing screw 22, a cup body 23, a spring assembly 24, a third fixing screw 25, and a sealing foam 26.

[0043] Specifically, the reflector cup connecting bracket 21 has a right-angle groove 27 for connecting with the docking post 15. When the reflector cup connecting bracket 21 is connected to the reflector cup connector 12, the docking post 15 is inserted into the groove of the right-angle groove 27, and then the reflector cup connecting bracket 21 is rotated to screw it into the other end of the right-angle groove 27 to complete the connection. The right-angle groove 27 of the reflector cup connecting bracket 21 is formed by spinning an aluminum plate. The toughness of the aluminum plate makes the L-shaped right-angle groove 27 less prone to breakage.

[0044] Understandably, the aluminum plate spinning process was chosen to process the reflector cup connecting bracket 21 in order to adapt to the structural toughness required when connecting it to the lamp head module 1, and to avoid breakage during installation or use; while the cup body 23 adopts the die casting one-piece molding process to meet the complex shape processing requirements of various arc contour structures, and to ensure the dimensional accuracy and reflection effect stability of different arc contours.

[0045] The reflective cup connecting bracket 21 is provided with a skirt component 28 for contacting the cup body 23. The skirt component 28 is sleeved on the cup body 23, and the second fixing screw 22 is threadedly connected to the skirt component 28. The cup body 23 has a threaded fixing hole that matches the second fixing screw 22. The skirt component 28 is fastened to the cup body 23 by the second fixing screw 22. The skirt component 28 has a positioning notch 29, and the cup body 23 has a positioning boss 210 that matches the positioning notch 29. The positioning boss 210 is inserted into the positioning notch 29. The positioning notch 29 and the positioning boss 210 are highly dimensionally matched, with a very small fit clearance and negligible positioning error. This high-precision fit ensures that when the reflector cup connecting bracket 21 and the cup body 23 are assembled, the various arc contour structures of the cup body 23 are precisely aligned with the light output direction of the lamp head module 1, avoiding the deviation of the light reflection path due to assembly misalignment, thereby preventing problems such as uneven wall washing spot and angle deviation, and ensuring the stability of the wall washing effect.

[0046] Furthermore, the cup body 23 has various curved contour structures inside. The light irradiated by the module body 11 is reflected through its internal contours, changing the light path to achieve the effect of washing the wall. The various curved contour structures inside the cup body 23 are integrally formed by die casting, and the various curved contours are made by integrally forming side walls with various different curved contours through die casting.

[0047] Specifically, the cup body 23 is provided with a fixed boss 211, and the fixed boss 211 is provided with two positioning protrusions, which can effectively prevent the lower edge of the spring assembly 24 from tilting up. Furthermore, the positioning protrusions are provided along the edge of the fixed boss 211, and their height is adapted to the thickness of the lower edge of the spring assembly 24. By abutting against the side of the lower edge of the spring assembly 24, the spring assembly 24 is restricted from tilting up in a direction perpendicular to the fixed boss 211. The fixed boss 211 is also provided with a threaded hole.

[0048] The spring assembly 24 includes a connecting frame 212, a spring body 213, and a ceiling mounting bracket 214. The connecting frame 212 has a folded edge plate 215 on one side, which is fixedly connected to the cup body 23. A rotating shaft is fixedly connected to the top of the connecting frame 212, and the spring body 213 is sleeved on the rotating shaft. The ceiling mounting bracket 214 is rotatably connected to the rotating shaft, and both ends of the spring body 213 are fixedly connected to the ceiling mounting bracket 214. The ceiling mounting bracket 214 has mounting holes, and fixing screws 25 are inserted into these holes. After passing through the mounting holes, the fixing screws 25 thread the connecting frame 212 and the cup body 23. Sealing foam 26 is fixedly connected to the end of the cup body 23 away from the lamp holder module 1, mainly serving to seal and buffer the gap during ceiling installation.

[0049] Please see Figure 7 , Figure 8 and Figure 9The core difference between the small, medium, and large models of the reflector cup assembly 2 lies in the size and internal curvature contour parameters of the cup body 23: the small model has a smaller overall size and a gentler internal curvature contour, suitable for narrow wall washing scenarios (such as small decorative walls or partial lighting for display cases), with a wall washing angle range of approximately 15° to 30°; the medium model has a moderate size and curvature contour of the cup body 23, suitable for conventional indoor walls (such as living room or corridor walls), with a wall washing angle range of approximately 30° to 60°; the large model has a larger size and a steeper internal curvature contour, suitable for wide wall washing scenarios (such as large exhibition hall walls or outdoor building facades), with a wall washing angle range of approximately 60° to 90°. The reflector cup connecting bracket 21 of the three models has the same structure and can all be adapted to the reflector cup connector 12 of the same lamp head module 1, achieving modular replacement.

[0050] Working principle: When the device is powered on, the light source in the lamp head module 1 emits light, which first undergoes preliminary light equalization and direction correction through the optical kit 14 at the bottom of the module body 11, so that the light enters the cup body 23 of the reflector cup assembly 2 at a uniform angle. The various arc contour structures within the cup body 23 perform stepped refraction and differentiated reflection of the light, precisely changing the light path and thus forming a wall-washing light spot that meets the needs of the scene (such as adjusting the width and uniformity of the light spot). If it is necessary to change the wall-washing angle, simply rotate the reflector cup connecting bracket 21 to disengage the docking post 15 from the right-angle slot 27, remove the original reflector cup assembly 2, replace it with a reflector cup assembly 2 with a cup body 23 of the corresponding arc contour, and re-connect and fix it to the right-angle slot 27 via the docking post 15. There is no need to replace the entire lamp. Meanwhile, the spring assembly 24 cooperates with the ceiling mounting bracket 214 through the rotating shaft, which can flexibly adapt to different ceiling installation angles. The positioning protrusion restricts the lower edge of the spring assembly 24 from tilting up, ensuring the structural stability after installation. The sealing foam 26 fills the gap between the cup body 23 and the ceiling to prevent dust and moisture from entering.

[0051] It should be understood that the above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. It should not be considered that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
