Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a faceplate, a downlight with the faceplate, and a lighting system including the downlight. Background Technology

[0002] Currently, downlight frames are typically made of plastic, and are mainly fastened to the heat sink using self-tapping screws. After the downlights are manufactured and assembled, quality inspection is required, and products that fail the inspection must be disassembled and repaired. However, the existing connection method has the following problems:

[0003] First, the connecting posts and self-tapping screws of the faceplate are prone to stripping and damage during repeated disassembly and assembly, reducing the reliability of the connection between the faceplate and the heat sink during secondary assembly and increasing the risk of the faceplate detaching from the heat sink. Second, some downlights require the installation of optical components (such as diffusers or lenses) on the faceplate, increasing the overall weight of the faceplate and further exacerbating the load on the connection structure, significantly increasing the risk of detachment. When the connecting posts cannot guarantee connection strength due to stripped or damaged threads, the faceplate must be scrapped, thus increasing the product's repair costs. Summary of the Invention

[0004] The main purpose of this utility model is to provide a faceplate that can significantly improve the connection strength with the heat sink, effectively reduce the risk of detachment after repair, and reduce the scrap rate of the faceplate due to connection failure, thereby reducing product repair costs.

[0005] Another objective of this invention is to provide a downlight with the aforementioned face frame.

[0006] Another object of this utility model is to provide a lighting system equipped with the above-mentioned downlight.

[0007] To achieve the main objective of this utility model, this utility model provides a face frame with a connecting post. The connecting post has a first connecting hole, the axis of which is parallel to the height direction of the face frame. The face frame has a mounting rib formed on the side facing away from the light source. The mounting rib has a second connecting hole that passes through the mounting rib and is perpendicular to the height direction.

[0008] As can be seen from the above, after adding the mounting rib, the faceplate can be fixed by screws passing through the connecting holes on the radiator and the second connecting hole of the mounting rib in sequence, which further strengthens the fixing effect between the faceplate and the radiator. The screws connected to the mounting rib can act as limit pins to prevent the faceplate from falling off due to stripping or damage of the first connecting hole during repeated disassembly and assembly.

[0009] A further option is to use two mounting ribs, which are evenly distributed along the circumference of the face frame.

[0010] As can be seen from the above, by designing the number and position of the mounting ribs, the mounting ribs can be connected to the connecting holes on the radiator used for mounting the side springs, thus eliminating the need to set additional connecting holes on the radiator.

[0011] A further improvement is to provide a reinforcing rib at the fixed end of the mounting rib, with the reinforcing rib located on the side of the mounting rib near the middle of the face frame.

[0012] As can be seen above, the screw may exert a thrust on the mounting rib during the process of passing through the second connecting hole. Setting a reinforcing rib on the back side of the mounting rib can increase the strength of the mounting rib and prevent excessive deformation and breakage at the fixed end of the mounting rib due to the thrust.

[0013] A further proposed solution is that the inner contour of the faceplate is in the shape of a truncated cone, with the lower base of the truncated cone located on the light-emitting side.

[0014] As can be seen from the above, this design helps to improve the lighting effect of the downlight and make the illumination range of the downlight wider.

[0015] To achieve another objective of this utility model, this utility model provides a downlight, including a heat sink and a light source assembly. The heat sink has a through hole, and the light source assembly is installed inside the heat sink. The downlight also includes the aforementioned face frame, a first screw, and a second screw. The light-emitting end of the light source assembly is positioned facing the face frame. The first screw passes through the through hole and is threadedly connected to the first connecting hole. The heat sink also has a third connecting hole, and the second screw is threadedly connected to the third connecting hole and passes through the second connecting hole.

[0016] As can be seen from the above, by setting the face frame, the second screw can act as a pin, and together with the mounting rib on the face frame, it restricts the movement of the face frame in its own height direction. Even if the first connecting hole experiences stripping or broken threads during repeated disassembly and assembly, the face frame can still be prevented from falling off the heat sink under the cooperation of the second screw and the mounting rib. This improves the connection strength and reliability between the face frame and the heat sink, thereby reducing the scrap rate of the face frame when the downlight is repaired, and thus reducing the repair cost.

[0017] A preferred embodiment is that the second screw is also threaded into the second connecting hole.

[0018] As can be seen from the above, this design can further improve the firmness of the connection between the faceplate and the heat sink, and better prevent the faceplate from shifting relative to the heat sink.

[0019] Another preferred embodiment is that the downlight also includes an optical element mounted on the faceplate, located between the light source assembly and the light-emitting side; the optical element is a diffuser or a lens.

[0020] As can be seen from the above, the arrangement of optical elements can improve the illumination effect of the light source assembly.

[0021] A further solution is to provide a side spring at each of the third connection holes of the heat sink. The side spring has a connection slot. The second screw passes through the connection slot and then connects to the third connection hole and the second connection hole. The face frame has an eave near the light-emitting side, and the eave and the side spring form a clamping position.

[0022] As can be seen from the above, the side spring can be assembled through the third connecting hole and the second screw, thus eliminating the need to add connecting holes and screws to the radiator, effectively reducing the processing steps of the radiator and lowering production costs.

[0023] A further improvement is that the face frame has a slot at the mounting rib, and the slot extends along the height direction from the top side of the face frame to the light-emitting side; the side spring includes a connecting piece, a clamping piece and a torsion spring, the connecting piece and the clamping piece are hinged, the connecting slot is provided on the connecting piece and passes through the connecting piece, the connecting piece also has a flange structure, the flange structure is inserted into the slot, and the torsion spring is connected between the connecting piece and the clamping piece, and the torsion spring forces the clamping piece to rotate towards the eaves.

[0024] As can be seen from the above, the design of the slot and the flange structure, and their cooperation, allow the side spring to be fixed to the heat sink with only a second screw, simplifying the side spring installation steps and helping to improve production efficiency.

[0025] To achieve another objective of this utility model, this utility model provides a lighting system, which includes the aforementioned downlight.

[0026] As can be seen from the above, lighting systems equipped with the aforementioned downlights offer higher safety. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0032] Downlight Example

[0033] Reference Figure 1 and Figure 2The downlight 100 includes a face frame 1, a heat sink 2, a light source assembly 3, a first screw 4, a second screw 5, an optical element 6, and a side spring 7.

[0034] Combination Figure 3 and Figure 4 In this embodiment, the face frame 1 is annular in shape and has a ring portion 11. A connecting post 12 is formed on the ring portion 11, and a first connecting hole 121 is provided on the connecting post 12. The axis of the first connecting hole 121 is parallel to the height direction of the face frame 1 (i.e., parallel to the axial direction of the ring portion 11), and the opening of the first connecting hole 121 is located on the inner side of the face frame 1 (i.e., the side of the face frame 1 closer to the heat sink 2). The first connecting hole 121 is connected to the heat sink 2 by a first screw 4 to achieve a fixed connection between the face frame 1 and the heat sink 2. Specifically, the heat sink 2 is provided with a through hole 21 that penetrates itself, and the axis of the through hole 21 is parallel to the height direction of the face frame 1. The through hole 21 is matched with the connecting post 12 on the face frame 1, so that when the heat sink 2 and the face frame 1 are assembled, the through hole 21 and the matched first connecting hole 121 are coaxially arranged. When assembling the face frame 1 and the heat sink 2, the first screw 4 is threaded through the through hole 21 and then threaded into the first connecting hole 121. Preferably, the through hole 21 is a countersunk hole to accommodate at least part of the head of the first screw 4. The number of first connecting posts 12 is equal to the number of through holes 21 and the number of first screws 4. The number of first connecting posts 12 is preferably between two and four, which ensures the firmness of the normal connection between the face frame 1 and the heat sink 2, simplifies the structure of the face frame 1 and / or the heat sink 2, and reduces the production cost of the face frame 1 and / or the heat sink 2.

[0035] Since the faceplate 1 is made of plastic, when the downlight 100 is inspected or repaired, the threads formed in the first connecting hole 121 of the first connecting post 12 are prone to stripping or breaking during repeated disassembly and assembly. This weakens the connection between the faceplate 1 and the heat sink 2, posing a risk that the faceplate 1 may detach from the heat sink 2. This risk is especially high when optical elements 6 are also installed on the faceplate 1, as their overall weight increases. To address this, the faceplate 1 is also provided with a mounting rib 13, located on the inner side of the faceplate 1 and at the end of the ring portion 11. The mounting rib 13 has a second connecting hole 131, which penetrates the mounting rib 13 and is parallel to a radial direction of the ring portion 11, such that the axis of the second connecting hole 131 is perpendicular to the height direction of the faceplate 1.

[0036] The second connecting hole 131 is connected to the radiator 2 via the second screw 5 to prevent the faceplate 1 from falling off the radiator 2. Specifically, the radiator 2 is also provided with a third connecting hole 22 that passes through it. The axis of the third connecting hole 22 is parallel to the axis of the second connecting hole 131, so that the third connecting hole 22 and the second connecting hole 131 are matched. When the radiator 2 and the faceplate 1 are assembled, the third connecting hole 22 and the second connecting hole 131 are arranged coaxially. When the second screw 5 is assembled with the faceplate 1 and the radiator 2, it first passes through the third connecting hole 22 and is threaded into the third connecting hole 22, and then passes through the third connecting hole 22, so that the second screw 5 acts as a limiting pin. With the cooperation of the second screw 5 and the mounting rib 13, the faceplate 1 is hung on the second screw 5, so as to solve the problem that the faceplate 1 falls off the radiator 2 when the first connecting hole 121 is stripped or damaged.

[0037] In this embodiment, the diameter of the second connecting hole 131 is preferably greater than or equal to the outer diameter of the thread of the second screw 5. It is understood that in some embodiments, the diameter of the second connecting hole 131 may also be smaller than the outer diameter of the thread of the second screw 5, so that when the second screw 5 passes through the second connecting hole 131, it is threadedly connected to the second connecting hole 131. This design can improve the firmness of the connection between the faceplate 1 and the heat sink 2, and better prevent the faceplate 1 from shifting relative to the heat sink 2 after installation.

[0038] Preferably, there are two mounting ribs 13, and the two mounting ribs 13 are evenly distributed along the axial direction of the face frame 1. Correspondingly, there are two third connecting holes 22 on the radiator 2, and the two third connecting holes 22 correspond one-to-one with the second connecting holes 131 of the two mounting ribs 13. Similarly, there are two second screws 5, and one second screw 5 is connected to one second connecting hole 131 and one third connecting hole 22. By designing the number and position of the mounting ribs 13, the second connecting holes 131 of the radiator 2 can be used to assemble with the side spring 7, thereby eliminating the need for additional connecting holes on the radiator 2 to assemble with the side spring 7. This reduces the processing steps of the radiator 2, simplifies the structure of the radiator 2, reduces the processing cost of the radiator 2, and shortens the processing cycle of the radiator 2.

[0039] Furthermore, a reinforcing rib 14 is provided at the fixed end of the mounting rib 13 (i.e., the connection between the mounting rib 13 and the ring portion 11), and the reinforcing rib 14 is located on the side of the mounting rib 13 near the middle of the face frame 1, that is, along the direction in which the second screw 5 is inserted into the second connecting hole 131, and the reinforcing rib 14 is located on the back side of the mounting rib 13. Since the second screw 5 may exert a thrust on the mounting rib 13 during the process of passing through the second connecting hole 131, especially when the second screw 5 is threadedly connected to the second connecting hole 131, the thrust on the mounting rib 13 is relatively large. Therefore, by providing a reinforcing rib 14 on the back side of the mounting rib 13, the reinforcing rib 14 can increase the structural strength of the mounting rib 13, thereby preventing the fixed end of the mounting rib 13 from breaking due to force, and preventing excessive deformation of the mounting rib 13, ensuring that the second screw 5 reliably passes through the second connecting hole 131.

[0040] The light source assembly 3 is installed in the heat sink 2, and the light-emitting point of the light source assembly 3 is oriented towards the face frame 1. The heat sink 2 is preferably made of aluminum alloy to ensure effective heat dissipation of the light source assembly 3, so as to ensure stable operation of the light source assembly 3 and extend the service life of the light source assembly 3.

[0041] Preferably, the inner ring 111 of the face frame 1 has a truncated cone shape, with the lower base of the truncated cone located on the light-emitting side. This design helps to improve the lighting effect of the downlight 100 and make the illumination range of the downlight 100 wider. As in this embodiment, the face frame 1 is annular, so the outline of the inner ring 111 of the ring portion 11 is frustum-shaped. It is understood that in other embodiments, the face frame 1 may be designed as a polygonal frame, in which case the outline of the inner ring 111 of the face frame 1 is correspondingly frustum-shaped.

[0042] Optical element 6 is mounted on face frame 1 and is located between the light source assembly 3 and the light-emitting side of face frame 1 to improve the illumination effect of light source assembly 3. In this embodiment, optical element 6 is a lens, with the large-diameter end of the lens connected to face frame 1 and the small-diameter end of the lens inserted into heat sink 2 and close to or attached to light source assembly 3; of course, as other optional solutions, in some embodiments, optical element 6 may also be a diffuser plate.

[0043] There are two side springs 7, each corresponding to one of the two third connecting holes 22. This means that one side spring 7 is installed in one third connecting hole 22, eliminating the need for additional connecting holes on the radiator 2 for connecting the side springs 7, and reducing the number of screws. This streamlines the processing steps of the radiator 2 and lowers production costs. In this embodiment, the side spring 7 includes a connecting piece 71, a clamping piece 72, and a torsion spring 73.

[0044] The connecting piece 71 has a connecting slot 711, which extends parallel to the height direction of the face frame 1. When the side spring 7 is assembled with the radiator 2, the second screw 5 first passes through the connecting slot 711, then through the third connecting hole 22 and is threaded into it, and finally passes through the second connecting hole 131. The design of the connecting slot 711 allows the position of the side spring 7 in the height direction of the face frame 1 to be adjustable, so as to ensure that the installation height of the two side springs 7 is consistent. It is understood that, as another optional solution, a through hole can also be used to replace the connecting slot 711.

[0045] Preferably, the face frame 1 has a slot 15 at the mounting rib 13, and the slot 15 extends along the height direction of the face frame 1 from the top side (i.e., the inner side of the face frame 1) to the light-emitting side of the face frame 1. A flange structure 712 is also formed on the connecting piece 71, so that when the side spring 7 is assembled, the flange structure 712 of the side spring 7 is also inserted into the slot 15 of the face frame 1, to prevent the side spring 7 from shifting position after installation and to ensure the firmness of the downlight 100 installed on the ceiling; wherein, the slot 15 can be injection molded together with the face frame 1, without the need for subsequent separate processing, making production more convenient. Furthermore, the design of the slot 15 and the flange structure 712, and their cooperation, allows the side spring 7 to be fixed to the heat sink 2 with only one second screw 5, simplifying the installation steps of the side spring 7 and improving the overall assembly efficiency of the downlight 100.

[0046] The clamping piece 72 of the side spring 7 is hinged to the connecting piece 71, allowing the clamping piece 72 to rotate relative to the connecting piece 71. An eaves 112 is formed on the face frame 1 near its light-emitting side, creating a clamping position between the eaves 112 and the clamping piece 72 of the side spring 7. The cooperation between the side spring 7 and the eaves 112 allows the downlight 100 to be clamped and fixed to the ceiling with mounting holes, eliminating the need for additional connectors to connect the downlight 100 to the ceiling. This simplifies the installation of the downlight 100, reduces installation costs, and improves installation efficiency.

[0047] A torsion spring 73 is connected between the connecting piece 71 and the clamping piece 72. The torsion spring 73 is used to force the clamping piece 72 to rotate toward the eaves 112 of the face frame 1 to ensure the reliability of the downlight 100 being clamped and fixed to the ceiling.

[0048] In summary, the design of the downlight 100 allows the second screw 5 to act as a pin, which, together with the mounting rib 13 on the faceplate 1, restricts the movement of the faceplate 1 in its height direction. This ensures that even if the first connecting hole 121 experiences stripping or damage during repeated disassembly and reassembly, the faceplate 1 can still be prevented from detaching from the heat sink 2 thanks to the combined action of the second screw 5 and the mounting rib 13. This improves the connection strength and reliability between the faceplate 1 and the heat sink 2, thereby reducing the scrap rate of the faceplate 1 during downlight 100 repairs and thus lowering repair costs.
