Description

Technical Field

[0001] This utility model relates to the field of downlight technology, specifically a split downlight cover and the downlight itself. Background Technology

[0002] Downlights are widely used due to their high brightness, safety, energy efficiency, and environmental friendliness. They also add a softer atmosphere to a space, creating a warm feeling and reducing the feeling of confinement. Whether in offices, exhibition spaces, or homes, downlights are commonly used to create comfortable lighting environments. Downlights are mostly installed by embedding them in the ceiling. The specific structure typically involves installing a torsion spring or spring clip on the back of the downlight's cover. The two elastic arms of the torsion spring or the two ends of the spring clip abut against the back of the ceiling, forming a connection between the downlight cover and the ceiling.

[0003] In existing technologies, the most widely used downlight structure is the integrated one-piece design. The downlight cover is typically designed as a single, inseparable unit, requiring a stretching process for integral molding during production. However, integrated downlight covers present significant disadvantages in production and transportation. In terms of production, the integrated structure can only be manufactured using a stretching process, resulting in extremely low production efficiency (3 minutes per piece). Furthermore, uneven stress during stretching can easily damage the cover, and it places extremely high demands on the material's ductility and toughness, thus increasing material costs. In terms of transportation, the inability to disassemble the integrated structure means that each cover occupies a large space, limiting the number that can be loaded within the same transport space. This leads to high packaging material consumption, high logistics costs, and low transportation efficiency. Moreover, due to the fixed structure, the size of the cover cannot be adjusted to meet actual needs, resulting in extremely poor flexibility.

[0004] In view of this, we have introduced a split-type downlight cover and its downlight. Utility Model Content

[0005] The purpose of this utility model is to provide a split downlight cover and downlight thereof to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a split-type downlight cover, comprising: an outer shell;

[0007] The housing includes a detachable upper cover and a lower cover. The surface of the lower cover has a slot for easy insertion. A fastener is integrally provided on one side of the slot on the surface of the lower cover.

[0008] The surface of the upper outer cover is provided with a concave plate for fixing the fastener. The surface of the upper outer cover below the concave plate is provided with a through groove for inserting the fastener. The upper outer cover is installed from the inside of the lower outer cover upwards. The lower outer cover is pushed so that the fastener is fully inserted into the through groove. The upper outer cover is then rotated, and the upper outer cover drives the concave plate to move in the slot so that the fastener fits tightly against the inner wall of the concave plate in the through groove, thus completing the assembly of the upper and lower outer covers.

[0009] Preferably, the surface of the upper outer cover is provided with a locking element on one side of the through groove.

[0010] This utility model also provides a downlight, which includes the above-mentioned split downlight cover.

[0011] Preferably, a lamp cover is detachably connected to the top of the housing, and a receiving cavity is provided inside the housing. The lamp cover is used to seal the top of the housing, and the detachable connection facilitates disassembly and transportation. Furthermore, the receiving cavity and the housing are integrally formed to facilitate the installation of the lamp.

[0012] The cavity also contains an LED board, which is detachably connected to the cavity. The LED board has LED beads in the center of its surface. The detachable connection of the LED board to the cavity facilitates subsequent disassembly, transportation and assembly.

[0013] Inside the housing, at the bottom of the LED board, there is a reflector cup. The reflector cup is used to converge and guide the light emitted by the LED beads on the surface of the LED board, improve the utilization rate of light and the directionality and concentration of the illumination, and at the same time, accurately guide the direction of light illumination, enhance the directionality and concentration of the lighting, and meet the usage needs of specific scenarios such as key area lighting and directional projection.

[0014] Preferably, the bottom surface of the LED board is connected to a screw A, and the top of screw A penetrates through the LED board and connects to the inside of the housing. This screw fixing method provides a firm and stable connection, which can effectively prevent the LED board from shifting due to vibration or other factors during transportation or use. At the same time, when disassembling, the LED board can be separated from the housing simply by unscrewing the screw, which is simple and convenient to operate without the need for complicated tools.

[0015] Preferably, the surface of the LED board has a screw hole for screw A to pass through. The preset position of the screw hole is precisely matched with the screw hole on the inner wall of the housing cavity, ensuring that screw A can pass through smoothly and be stably fixed, avoiding installation difficulties due to hole position deviation, and improving the accuracy and efficiency of assembly.

[0016] Preferably, screws B are connected to the top two sides of the lamp cover, and the bottom of the screws B extends through the lamp cover and into the housing. The symmetrical arrangement of screws B on both sides can make the connection between the lamp cover and the housing evenly stressed, enhance the tightness of the top seal, and the symmetrical structure also facilitates quick alignment of the holes during installation, further simplifying the operation process.

[0017] Preferably, the surface of the outer shell is connected to a lighting spring clip by bolts. The bolt connection ensures that the spring clip is stably connected to the outer shell and is not easy to fall off. The lighting spring clip can adapt to different sizes of mounting holes by its own elastic deformation, so as to quickly fix the downlight to the ceiling and other mounting carriers without the need for additional drilling or welding, and is suitable for a variety of installation environments.

[0018] Preferably, the interior of the receiving cavity is further provided with a support plate at the bottom of the reflector cup, and the surface of the support plate is provided with a through groove A for installation. The bottom of the support plate is connected to the inner ring of the downlight, and the surface of the inner ring of the downlight is provided with a through groove B for aligning with the through groove A. The support plate can provide stable support for the reflector cup, preventing the reflector cup from shifting and affecting the light focusing effect. The precise alignment of through groove A and through groove B facilitates the firm connection between the support plate and the inner ring of the downlight through bolts or other connecting parts, ensuring the overall stability of the assembled components.

[0019] Preferably, the bottom of the outer shell is provided with a light-transmitting lamp cover plate at the bottom of the inner ring of the downlight. The light-transmitting lamp cover plate can shield and protect the internal components of the housing cavity without affecting the light output, preventing foreign objects from directly contacting the reflector cup, LED plate and other core components. At the same time, it can also soften the light and improve the comfort of lighting.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] (1) The split structure design of the upper and lower outer covers allows each component to be produced separately and assembled flexibly. The production of the integrated type takes 3 minutes per piece, while the stamping of the split type takes 5 seconds per piece. The integrated type can only be stretched, which is easy to break and has high material requirements. The split type can be directly stamped. The split type can be assembled together, which greatly reduces the space occupied. Compared with the integrated type, the downlights can be transported in 3 times more quantities, reducing the packaging and logistics costs during transportation and improving transportation efficiency and economy. The size of the shell of the split type can be varied.

[0022] (2) By centering the LED beads on the LED board to ensure symmetrical light output, and with the reflector cup with high reflectivity on the inner wall, the scattered light emitted by the LED beads can be effectively gathered, reducing the ineffective loss of light and significantly improving the light utilization rate; the bottom light-transmitting lamp cover plate is made of high light transmittance material, which can not only ensure efficient light transmission, but also filter stray light, making the output light soft and uniform, avoiding direct glare, and creating a comfortable lighting environment;

[0023] (3) The downlight can be quickly fixed by the elastic deformation of the light fixture spring clip, without complicated installation procedures. Whether it is the initial installation or the later adjustment, it can save a lot of manpower and time costs and adapt to the needs of various installation scenarios.

[0024] (4) The housing cavity provides a closed installation space for all core components. The lamp cover seals the top, which can effectively prevent dust, moisture and other impurities from entering the interior, protect the LED board, lamp beads and other electronic components, and extend the service life of the downlight.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0037] Please see Figures 1-8 This utility model provides a technical solution: a split downlight cover, including: an outer shell 1, the outer shell 1 is split by a detachable connection between an upper outer cover 110 and a lower outer cover 114, the cooperation logic of the two revolves around "precise positioning and stable locking", the holes and grooves 115 on the surface of the lower outer cover 114 provide a channel for the movement of the concave plate 111 of the upper outer cover 110; and the fastener 116 integrally formed with the lower outer cover 114 is the core "bridge" connecting the upper and lower outer covers, the integral forming process ensures its structural strength and avoids the problems of breakage and loosening during long-term use;

[0038] The upper outer cover 110 is structurally designed to perfectly fit the lower outer cover 114: the concave plate 111 is used to fit tightly with the fastener 116, achieving dual longitudinal and lateral limiting; the through groove 113 provides an insertion channel for the fastener 116, ensuring the accuracy of the initial insertion. During assembly, the upper outer cover 110 is installed upward from inside the lower outer cover 114. After pushing, the fastener 116 is fully inserted into the through groove 113. Then, by rotating the upper outer cover 110, the concave plate 111 is moved within the slot 115, ultimately allowing the fastener 116 to fit tightly against the inner wall of the concave plate 111, completing a stable assembly.

[0039] In addition, the locking element 112 on the surface of the upper outer cover 110 can further strengthen the connection and prevent the upper and lower outer covers from loosening in the event of vibration, collision and other scenarios, thereby improving the overall structural reliability.

[0040] This utility model also provides a downlight, which includes the above-mentioned split downlight cover.

[0041] As the core frame of the downlight cover, the outer shell 1 plays a crucial role in supporting the various components and protecting the internal structure. Its design takes into account both the convenience of separation and structural stability. The top of the outer shell 1 and the lamp cover 2 are detachably connected. On the one hand, the lamp cover 2 can tightly seal the top of the outer shell 1, effectively preventing external impurities such as dust and moisture from entering the interior and avoiding contamination or damage to the internal lighting components. On the other hand, the detachable design greatly reduces the difficulty of transportation. The one-piece molded cavity 4 inside the outer shell 1 is the installation base for the core components of the lighting fixture.

[0042] The cavity 4 is also equipped with an LED board 5. The LED board 5 is detachably connected to the cavity 4, and the LED bead 15 is located in the center of the surface of the LED board 5. The detachable connection of the LED board 5 to the cavity 4 facilitates subsequent disassembly, transportation and assembly.

[0043] The LED board 5 inside the housing 4 is the core of the downlight. It is fixed by a detachable connection method. The screw A6 passes through the screw hole 13 on the surface of the LED board 5 and is connected to the inside of the housing 1. This ensures that the LED board 5 is firmly installed and facilitates subsequent disassembly, replacement or maintenance. At the same time, the detachable design also reduces the risk of damage during transportation. The LED beads 15, which are set in the center of the surface of the LED board 5, can provide a concentrated and uniform light source to meet the basic lighting needs.

[0044] The reflector cup 7 located at the bottom of the LED panel 5 plays a key role in "light optimization": through its special curved structure, it can converge and guide the scattered light emitted by the LED beads 15, effectively reducing light waste and improving light utilization. At the same time, the directional guidance function can concentrate the light on the target area, enhance the directionality and concentration of the lighting, and avoid the problem of poor lighting effect caused by light dispersion. It is suitable for scenarios that require precise lighting, such as living rooms, studies, and office areas.

[0045] The light fixture spring clip 3 is bolted to the surface of the outer shell 1 and is the core component for connecting the downlight to the mounting carrier such as the ceiling or suspended ceiling. The elastic structure of the light fixture spring clip 3 can adapt to mounting carriers of different thicknesses. During installation, simply compress the spring clip and insert it into the mounting hole. After releasing, it can be firmly fixed by the elastic force, without the need for complicated drilling or welding operations, which greatly improves the convenience of installation.

[0046] The support plate 8 is located at the bottom of the reflector cup 7. The through groove A9 on its surface is aligned with the through groove B11 on the surface of the inner ring 10 of the downlight. The two work together to form a stable internal support structure, which can not only fix the reflector cup 7, the light-transmitting lamp cover plate 12 and other components, but also disperse external pressure and protect the core components such as the internal LED board 5 from external damage. At the same time, through grooves A9 and B11 also reserve space for wiring and accessory installation, improving structural flexibility.

[0047] The light-transmitting lamp cover 12 is located at the bottom of the outer shell 1 and below the inner ring 10 of the downlight. It is made of a high light-transmitting material, which can not only allow the light optimized by the reflector cup 7 to pass through efficiently, but also block dust, insects and other objects from entering the housing cavity 4, avoid contaminating the LED panel 5 and the reflector cup 7, ensure the long-term stable lighting effect of the downlight, and at the same time play a certain role in anti-glare, improving the comfort of use.

[0048] The lamp cover 2 extends into the housing 1 through the screw B14. Compared with a simple snap-fit ​​connection, the screw fixation can further improve the sealing performance between the lamp cover 2 and the housing 1, effectively preventing moisture and dust from entering the receiving cavity 4. At the same time, the detachability of the screw connection is still retained, which makes it convenient to open the lamp cover 2 for subsequent maintenance of internal components.

[0049] From the lamp cover 2 and outer shell 1, the upper outer cover 110 and lower outer cover 114, to the LED board 5 and the receiving cavity 4, all adopt a detachable design, forming a unified "modular" structure. This design not only allows for disassembly and packaging during transportation, reducing transportation costs and the risk of damage, but also allows for the removal of only the corresponding parts during later maintenance, without the need for overall disassembly, greatly improving maintenance efficiency and reducing maintenance costs.

[0050] Specifically, in use, the outer shell 1 consists of an upper outer cover 110 and a lower outer cover 114, which are detachably connected to form a split structure. The surface of the lower outer cover 114 not only has holes and slots 115 for inserting external components, but also has a fastener 116 integrally formed on one side of the holes and slots 115. The fastener 116 is the core "connector" connecting the upper and lower outer covers. The surface of the upper outer cover 110 is provided with a concave plate 111 and a through groove 113. The concave plate 111 is used to fit and limit the fastener 116, and the through groove 113 is used for the fastener 116 to be inserted. Together, they constitute the "connection and adaptation structure" of the upper outer cover 110, providing a precise fit basis for subsequent assembly.

[0051] During assembly, an "inside-up installation" orientation method is adopted: the upper outer cover 110 is placed upward from the inside of the lower outer cover 114, so that the through groove 113 of the upper outer cover is aligned with the fixing member 116 of the lower outer cover. Then, the lower outer cover 114 is pushed or the upper outer cover 110 is pushed in the opposite direction, so that the fixing member 116 of the lower outer cover is fully inserted into the through groove 113 along the opening direction of the through groove 113. At this time, the fixing member 116 is wrapped by the through groove 113, and the upper outer cover 110 and the lower outer cover 114 achieve preliminary insertion and positioning, avoiding lateral displacement during the assembly process.

[0052] After the fastener 116 is inserted, rotate the upper outer cover 110: when the upper outer cover 110 rotates, it will drive the concave plate 111 on its surface to move synchronously. Since the concave plate 111 is set to correspond to the slot 115 of the lower outer cover, the concave plate 111 will rotate with the upper outer cover 110 within the range of the slot 115. When rotated to a specific angle, the fastener 116 inserted into the through slot 113 will fit tightly against the inner wall of the concave plate 111. The groove structure of the concave plate 111 will form a "wrap-type limit" for the fastener 116, restricting the longitudinal movement and rotation of the fastener 116 in the through slot 113, so that the upper outer cover 110 and the lower outer cover 114 transition from "initial insertion" to "stable assembly" state, completing the core assembly process of the outer shell 1.

[0053] After the fastener 116 is attached to the concave plate 111, the fastener 116 contacts the locking member 112, thereby further restricting the movement space of the fastener 116 and preventing the upper outer cover 110 and the lower outer cover 114 from loosening due to external vibration or collision, thus forming a "double fixing" effect.

[0054] The split structure design of the upper outer cover 110 and the lower outer cover 114 allows each component to be produced separately and assembled flexibly. The production of the integrated unit takes 3 minutes per piece, while the stamping of the split unit takes 5 seconds per piece. The integrated unit can only be stretched, which is easy to break and has high material requirements. The split unit can be directly stamped. The split units can be assembled together, which greatly reduces the space occupied. Compared with the integrated downlight, it can transport 3 times more, reduce packaging and logistics costs during transportation, and improve transportation efficiency and economy. The size of the split outer shell 1 is variable.

[0055] The outer shell 1 serves as the core load-bearing structure, and its top is detachably connected to the lamp cover 2 via screw B14. During installation, the lamp cover 2 is placed over the opening at the top of the outer shell 1, aligning the screw holes of the lamp cover 2 with the pre-set screw holes at the top of the outer shell 1. Then, screw B14 is inserted through the lamp cover 2 and screwed into the interior of the outer shell 1 to complete the top seal. During disassembly, screw B14 is simply unscrewed in the reverse direction to separate the two. This structure ensures the airtightness of the interior of the outer shell and provides convenience for subsequent maintenance and transportation.

[0056] LED board 5 is fixed to the receiving cavity 4 of housing 1 by screw A6. During installation, the screw hole 13 on the surface of LED board 5 is aligned with the screw hole on the inner wall of receiving cavity 4. Screw A6 is screwed into housing 1 through screw hole 13 from the bottom of LED board 5 to achieve stable fixation of LED board 5. When disassembling, screw A6 is unscrewed to remove LED board 5, which is convenient for replacing or repairing LED beads 15.

[0057] The components are assembled in layers in the cavity 4 in the order of "light source - reflection - support - light transmission": LED plate 5 is fixed to the upper part of cavity 4, and the lamp bead 15 in the center of it serves as the core of the light source; reflector cup 7 is placed directly below LED plate 5 and is precisely aligned with lamp bead 15; support plate 8 is located at the bottom of reflector cup 7, its top supports reflector cup 7, and its bottom is connected to the inner ring 10 of downlight, and the through groove A9 of support plate 8 is aligned with the through groove B11 of inner ring 10 of downlight, and the two can be fixed by bolts or other connecting parts passing through the double through grooves; finally, light transmission cover plate 12 is installed at the bottom of housing 1, covering the bottom of inner ring 10 of downlight, forming a closed light output channel;

[0058] The lighting spring clip 3, which is bolted to the surface of the outer shell 1, is used for the overall installation of the downlight. During installation, the downlight is embedded in the ceiling or a pre-set mounting hole. The tension generated by the elastic deformation of the lighting spring clip 3 makes the spring clip fit tightly against the inner wall of the mounting hole, thereby fixing the downlight stably. Installation can be completed without complicated tools.

[0059] When the external circuit is powered on, the current is transmitted to the LED board 5 through the wires. The LED beads 15 on the LED board 5 convert electrical energy into light energy and emit initial light. The centered placement of the LED beads 15 ensures the symmetry of the light output. The light emitted by the LED beads 15 diffuses in all directions. The light emitted downward and to the side will illuminate the inner wall of the reflector cup 7. The reflector cup 7 adopts a parabolic or conical reflective structure. Its inner wall is treated with high reflectivity (such as aluminum plating, polishing, etc.), which can reflect and converge the scattered light that illuminates the surface into a parallel or nearly parallel beam. At the same time, it guides the light to concentrate in the downward light transmission direction, reducing the ineffective loss of light.

[0060] After being converged by the reflector cup 7, the light passes downward through the gap between the support plate 8 and the inner ring 10 of the downlight, and is finally output through the light-transmitting lamp cover plate 12. The light-transmitting lamp cover plate 12 is made of high light transmittance material (such as acrylic, glass, etc.), which can filter some stray light while ensuring efficient light transmission, making the output light softer and more uniform, and avoiding direct glare.

[0061] When the downlight is turned on, the LED beads 15 of the LED board 5 provide the light source, and the reflector 7 immediately converges and guides the scattered light. The regulated light passes through the cooperation space between the support plate and the inner ring of the downlight, and is finally output to the environment by the light-transmitting cover plate 12. The housing cavity 4 of the outer shell 1 provides a closed installation space for all core components, the lamp cover 2 seals the top to prevent dust and moisture from entering, and the lamp spring clip 3 ensures the stability of the overall structure in the installation position. Each component has a clear division of labor and works together to achieve the complete function of "stable light source output - efficient light regulation - safe and fixed structure".

[0062] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
