Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology, specifically to a faceplate optical module and a downlight equipped with the optical module. Background Technology
[0002] The existing downlight cover structure has two main defects:
[0003] First, the faceplate cannot be compatible with different optical components (such as diffuser plates, lenses, etc.) at the same time. Faceplates that are adapted to specific types of optical components need to be designed separately, which leads to an increase in the number of molds and a longer development cycle.
[0004] Second, the waterproof structure of the cover can only meet a single protection level (such as IP20 or IP54), and cannot achieve different protection levels through simple assembly structure adjustments.
[0005] The aforementioned defects result in insufficient product versatility and low production flexibility, significantly increasing mold and development costs. Summary of the Invention
[0006] To address the aforementioned issues, the primary objective of this invention is to provide a faceplate optical module that is compatible with both diffuser plates and lenses, and also compatible with two levels of protection.
[0007] Another objective of this invention is to provide a downlight equipped with the aforementioned optical module with a faceplate.
[0008] For the main purpose of this utility model, this utility model provides a faceplate optical module, which includes a faceplate and an optical component. The faceplate has a ring portion, a flange portion and a retaining portion. The flange portion and the retaining portion are both connected to the inner ring of the ring portion. The retaining portion surrounds the flange portion and forms a waterproof groove with the flange portion. The optical component is located inside the retaining portion and adjacent to the flange portion. The optical component covers the opening of the waterproof groove.
[0009] As can be seen from the above, the design of the flange and the enclosure allows them to be assembled with different optical components (such as diffusers and lenses), enabling the faceplate to be compatible with different types of optical elements, improving the faceplate's compatibility and versatility, and reducing the number of molds, development cycle, and production costs. Furthermore, since the faceplate can be compatible with different types of optical elements such as diffusers and lenses, it can also improve the flexibility of product production and reduce the risk of inventory backlog. In addition, depending on the product's protection level (including waterproof and dustproof levels), it is possible to choose whether to install a seal in the waterproof groove, allowing the faceplate optical module to change its protection level without changing the faceplate structure, thus meeting the usage requirements of different scenarios.
[0010] In a preferred embodiment, the faceplate optical module further includes a first sealing ring, which is detachably installed in a waterproof groove and abuts against the optical component.
[0011] As can be seen from the above, by setting the first sealing ring in the waterproof groove, the protection level of the optical module of the faceplate can be improved; and this design also facilitates the disassembly and replacement of the first sealing ring.
[0012] A further embodiment is that the ring portion has a first connecting post on the outer periphery of the enclosure portion; the enclosure portion has a first clearance opening at the first connecting post, and the first clearance opening penetrates the enclosure portion; the faceplate optical module also includes a first locking member, the first locking member having a first connecting portion and a first pressing portion, the first connecting portion being connected to the first connecting post, and a portion of the first pressing portion passing through the first clearance opening and forming a first clamping position with the flange portion and the enclosure portion.
[0013] As can be seen from the above, this design can improve the robustness of the diffuser plate or lens after assembly with the faceplate, and can better ensure the protective effect when the first sealing ring is provided in the waterproof groove.
[0014] A further alternative is that the optical component is a diffuser plate; or the optical component is a lens with an apex that covers the opening and can be clamped and fixed in a first clamping position.
[0015] As can be seen from the above, the rim on the lens can improve the reliability and firmness of the locking mechanism in locking the lens onto the faceplate.
[0016] A further embodiment includes a second connecting post on the outer periphery of the enclosure portion; the enclosure portion has a second clearance opening at the second connecting post, the second clearance opening penetrating the enclosure portion; the faceplate optical module also includes a second locking member, the second locking member having a second connecting part and a second pressing part, the second connecting part being connected to the second connecting post, and a portion of the second pressing part passing through the second clearance opening and forming a second clamping position with the flange portion and the enclosure portion; one of the diffuser plate and the eaves portion can be clamped and fixed in the first clamping position, and the other can be clamped and fixed in the second clamping position.
[0017] As can be seen from the above, by adding a second locking component and a second connecting post on the faceplate, one of the first locking component and the second locking component can be used to lock and fix the diffuser plate in a targeted manner, and the other can be used to lock and fix the lens in a targeted manner, thereby improving the locking and fixing effect of the diffuser plate and the lens.
[0018] Another preferred embodiment is that the optical component is a diffuser plate, which is welded and fixed to the enclosure and / or the flange.
[0019] As can be seen from the above, this design makes it easier to fix the diffuser plate and the cover, and can effectively reduce the number of assembly parts, thereby improving assembly efficiency and reducing costs.
[0020] A further design is that the inner wall of the ring portion is formed as a first frustum, with the top of the first frustum close to the inner side of the cover; the flange portion and the enclosure portion are connected to the top of the first frustum, and the flange portion is located on the extension surface of the first frustum and is formed as a second frustum.
[0021] As can be seen from the above, the first frustum of the ring and the second frustum of the flange can improve the lighting effect of the lamp equipped with the optical module of this face cover, so that the lamp has a wider illumination range.
[0022] A further proposed solution is to install a third connecting post on the outer perimeter of the enclosure.
[0023] As can be seen above, the third connecting post is used to assemble the faceplate with other components of the lamp (such as the heat sink).
[0024] To achieve another objective of this utility model, this utility model provides a downlight, including a heat sink and a light source assembly. The light source assembly is installed inside the heat sink. The downlight also includes the aforementioned faceplate optical module. The heat sink is connected to the faceplate, and the light-emitting end of the light source assembly is positioned facing the optical component.
[0025] As can be seen from the above, by adopting the aforementioned faceplate optical module, the downlight can selectively be configured with a diffuser plate or lens to achieve the switching of different product models. This eliminates the need to design a faceplate for each model, improves product production flexibility, reduces the risk of inventory backlog, and also reduces the number of molds, development cycle and production costs.
[0026] A further design includes a mounting groove at the end of the radiator near the downlight; the downlight also includes a second sealing ring, which is installed in the mounting groove and abuts against the cover.
[0027] As can be seen from the above, this design can further improve the protective effect of the downlight, prevent external moisture from entering the downlight through the gap between the radiator and the cover, better protect the light source components and other electronic components, avoid damage to electronic components due to moisture, short circuits, etc., ensure the safety of the downlight and extend its service life.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation
[0037] Downlight Example
[0038] Reference Figure 1 , Figure 2 and Figure 6 The downlight 100 includes a faceplate optical module 1, a heat sink 2, a light source assembly 3, and a third locking member 4. The faceplate optical module 1 includes, but is not limited to, a faceplate 11, optical components, a first sealing ring 14, and a first locking member 15; wherein, the optical components can be a diffuser plate 12 or a lens 13, that is, the faceplate 11 can be assembled with different types of optical components, thereby improving the versatility of the faceplate 11.
[0039] Combination Figure 3The cover 11 has a ring portion 111, a flange portion 112 and a retaining portion 113. The flange portion 112 and the retaining portion 113 are both connected to the inner ring of the ring portion 111 and integrally formed with the ring portion 111, and the retaining portion 113 surrounds the flange portion 112; wherein, a waterproof groove 114 is formed between the retaining portion 113 and the flange portion 112. Preferably, the inner wall of the ring portion 111 is provided as a first frustum 1113. The top of the first frustum 1113 (i.e., the small diameter end of the first frustum 1113) is close to the inner side of the cover 11 (i.e., the end of the cover 11 close to the radiator 2). It can be understood that the bottom of the first frustum 1113 (i.e., the large diameter end of the first frustum 1113) is preferably provided close to the bottom of the cover 11 (i.e., the outer side of the cover 11, the end from which the light source assembly 3 emits light). The flange portion 112 and the enclosure portion 113 are connected to the top of the first frustum 1113, and the enclosure portion 113 preferably extends in the height direction of the downlight 100. The flange portion 112 is located on the extension surface of the first frustum 1113 and is provided as a second frustum 1121. The inner ring wall of the ring portion 111 and the flange portion 112 are designed in the shape of a frustum to avoid the inner ring wall of the ring portion 111 and the flange portion 112 blocking the light source assembly 3, so that the downlight 100 can have a wider illumination range and improve the lighting effect of the downlight 100.
[0040] When the diffuser plate 12 is assembled with the cover 11, the diffuser plate 12 is located inside the enclosure portion 113 and adjacent to the flange portion 112, and the diffuser plate 12 covers the opening of the waterproof groove 114. In this embodiment, two or more first connecting posts 1111 are formed on the ring portion 111. The two or more first connecting posts 1111 surround the outer periphery of the enclosure portion 113, and the enclosure portion 113 is provided with a first clearance opening 1131 at each first connecting post 1111. The first clearance opening 1131 penetrates the enclosure portion 113. In addition, the faceplate optical module 1 also includes a first locking member 15. The first locking member 15 has a first connecting portion 151 and a first pressing portion 152. The first connecting portion 151 is connected to the first connecting post 1111. A portion of the first pressing portion 152 passes through the first clearance opening 1131 and forms a first clamping position with the flange portion 112 and the enclosure portion 113. The diffuser plate 12 is clamped and fixed in the first clamping position. When the diffuser plate 12 is clamped, the portion of the first pressing portion 152 passing through the first clearance opening 1131 presses and fixes the edge of the diffuser plate 12 to the flange portion 112 to prevent the diffuser plate 12 from loosening. This design helps to better ensure the secure installation of the diffuser plate 12 onto the cover 11, and also better ensures the protective effect when the first sealing ring 14 is provided in the waterproof groove 114. Preferably, the first locking member 15 is a bolt, that is, the first connecting part 151 is a stud and the first clamping part 152 is a nut. Furthermore, in the height direction of the downlight 100, the projection of the portion of the first clamping part 152 passing through the first clearance opening 1131 is located within the projection of the waterproof groove 114, so as to avoid the first clamping part 152 blocking the light source assembly 3 and ensuring the lighting effect.
[0041] In some embodiments, the first connecting post 1111 may not be provided on the ring portion 111, and the faceplate optical module 1 may not include the first locking member 15. In this case, the diffuser plate 12 may be press-fitted with the inner peripheral surface of the enclosure portion 113 through its own outer peripheral surface, and / or the diffuser plate 12 may be pressed and fixed by the components inside the downlight 100, so that the diffuser plate 12 is pressed and fixed on the flange portion 112; or the diffuser plate 12 may be welded and fixed to the flange portion 112 and / or the enclosure portion 113. This design makes the fixed connection between the diffuser plate 12 and the faceplate 11 more convenient, and can effectively reduce the number of assembly parts, thereby improving assembly efficiency and reducing costs.
[0042] The protection level (including waterproof and dustproof levels) of the downlight 100 and the optical module 1 of the faceplate can be changed by whether or not a first sealing ring 14 is provided in the waterproof groove 114. This allows the protection level of the downlight 100 and the optical module 1 of the faceplate to be changed according to the usage scenario and usage requirements, and the protection level can be changed without changing the structure of the faceplate 11, meeting the usage requirements of different scenarios and improving the versatility and practicality of the faceplate 11. Figure 2As shown, in some embodiments, when the first sealing ring 14 is not installed in the waterproof groove 114, an IP20 protection level can be achieved through the cooperation between the waterproof groove 114 and the diffuser plate 12. Figure 4 and Figure 5 As shown, in some embodiments, when the first sealing ring 14 is installed in the waterproof groove 114, the first sealing ring 14 abuts against the flange portion 112, the enclosure portion 113 and the diffuser plate 12 respectively. Through the cooperation of the waterproof groove 114, the diffuser plate 12 and the first sealing ring 14, the protection level of IP54 can be achieved.
[0043] Combination Figures 6 to 8 When the lens 13 is assembled with the cover 11, the lens 13 is inserted into the enclosure portion 113 and adjacent to the flange portion 112, and the lens 13 covers the opening of the waterproof groove 114. In this embodiment, the lens 13 and the diffuser plate 12 can share the same connecting post (i.e., the first connecting post 1111) and the same locking member (i.e., the first locking member 15). Preferably, the large-diameter end of the lens 13 has an eave 131, such that when the lens 13 is inserted into the enclosure portion 113, the eave 131 is adjacent to the flange portion 112 and covers the opening of the waterproof groove 114. When the first locking member 15 cooperates with the flange portion 112 and the enclosure portion 113 to lock and fix the lens 13, the first pressing part 152 of the first locking member 15 passes through the first clearance opening 1131 and presses the eave 131 onto the flange portion 112 to prevent the lens 13 from loosening. The lens 13 is provided with an eave 131, which can improve the reliability and firmness of the locking member in locking the lens 13 onto the cover 11, and ensure the protective effect when the first sealing ring 14 is provided in the waterproof groove 114. In the height direction of the downlight 100, the projection of the portion of the first pressing part 152 passing through the first clearance opening 1131 and the projection of the eave 131 are both located within the projection of the waterproof groove 114 to ensure the lighting effect.
[0044] Similarly, in some embodiments, when the first connecting post 1111 is not provided on the ring portion 111 and the faceplate optical module 1 does not include the first locking member 15, the lens 13 can be pressed and fixed on the flange portion 112 by the interference fit between the outer peripheral surface of the eaves portion 131 and the inner peripheral surface of the enclosure portion 113, and / or by the pressing and fixing of the components inside the downlight 100. Of course, in some embodiments, a second connecting post can also be added to the ring portion 111. Similarly, the enclosure portion is provided with a second clearance opening at the second connecting post, the second clearance opening penetrates the enclosure portion 113, and the faceplate optical module 1 also includes a second locking member. The second locking member has a second connecting portion and a second pressing portion. The second connecting portion is connected to the second connecting post, and part of the second pressing portion passes through the second clearance opening and forms a second clamping position with the flange portion 112 and the enclosure portion 113. Since the setting method of the second locking member is similar to the setting method of the first locking member 15, it will not be described again here. In this design, one of the diffuser plate 12 and the lens 13's eaves 131 can be clamped and fixed in the first clamping position, and the other can be clamped and fixed in the second clamping position. Although this design will increase the structural complexity and production cost of the cover 11 to some extent, by adding a second locking member and a second connecting post on the cover 11, one of the first locking member 15 and the second locking member can be used to lock and fix the diffuser plate 12, and the other can be used to lock and fix the lens 13, thereby improving the locking and fixing effect of the diffuser plate 12 and the lens 13.
[0045] like Figures 6 to 8 As shown, in some embodiments, when the first sealing ring 14 is installed in the waterproof groove 114, the first sealing ring 14 abuts against the flange portion 112, the enclosure portion 113, and the eaves portion 131, respectively. Through the cooperation of the waterproof groove 114, the lens 13, and the first sealing ring 14, an IP54 protection level can be achieved. In some embodiments, when the first sealing ring 14 is not installed in the waterproof groove 114, an IP20 protection level can be achieved through the cooperation of the waterproof groove 114 and the lens 13.
[0046] In addition, two or more third connecting posts 1112 are formed on the ring portion 111. The two or more third connecting posts 1112 surround the outer periphery of the enclosure portion 113. The third connecting posts 1112 are used to connect with the radiator 2. Specifically, the radiator 2 is provided with connecting holes. When the radiator 2 is assembled with the cover 11, the radiator 2 and the cover 11 are fixedly connected by passing the third locking member 4 through the connecting hole and connecting it with the third connecting post 1112.
[0047] Preferably, the heat sink 2 has a mounting groove 21 at one end near the downlight 100; the downlight 100 also includes a second sealing ring 5, which is installed in the mounting groove 21 and abuts against the cover 11. This design can further improve the protective effect of the downlight 100, preventing external moisture from entering the downlight 100 through the gap between the heat sink 2 and the cover 11, so as to better protect electronic components such as the light source assembly 3, avoid damage to electronic components due to moisture, short circuits, etc., ensure the safety of the downlight 100 in use, and extend the service life of the downlight 100.
[0048] The light source assembly 3 is installed inside the heat sink 2, allowing the heat sink 2 to dissipate heat from the light source assembly, ensuring the stability of the light source assembly 2's operation and helping to extend its service life. The light-emitting end of the light source assembly 3 is positioned facing an optical element (such as a diffuser plate 12 or a lens 13), enabling the diffuser plate 12 or lens 13 to improve the lighting effect of the downlight 100.
[0049] In this embodiment, the heat sink 2 is preferably made of aluminum alloy, which allows the downlight 100 to be designed to be more compact and / or the light source component 3 to have greater power. It is understood that in some embodiments, the heat sink 2 may also be an injection molded part. It should be noted that even if the heat sink 2 is an injection molded part, it can still ensure that the light source component 3 is effectively cooled. Injection molded heat sink 2 is also widely used in the prior art. However, the disadvantage of using injection molded heat sink 2 is that the downlight 100 needs to be designed to be larger and the power of the light source component 3 cannot be too high.
[0050] In summary, the design of the faceplate optical module 1 allows the flange 112 and the enclosure 113 to be assembled with different types of optical components such as the diffuser plate 12 or the lens 13, enabling the faceplate 11 to be compatible with different types of optical components. This improves the compatibility and versatility of the faceplate 11, and reduces the number of molds, development cycle, and production costs. Furthermore, since the faceplate 11 is compatible with different types of optical components such as the diffuser plate 12 and the lens 13, it also enhances the flexibility of product manufacturing and reduces the risk of inventory backlog. In addition, depending on the product's protection level (including waterproof and dustproof levels), it is possible to choose whether to install a seal in the waterproof groove 114, allowing the faceplate optical module 1 to change its protection level without altering the structure of the faceplate 11, thus meeting the usage requirements of different scenarios. By adopting the aforementioned faceplate optical module 1, the downlight 100 can selectively be configured with a diffuser plate 12 or a lens 13 to achieve switching between different product models. This eliminates the need to design a faceplate 11 for each model, thereby improving product production flexibility, reducing the risk of inventory backlog, and also reducing the number of molds, development cycle, and production costs.

[0052] The lighting system includes a control terminal and the downlights described in the above-described downlight embodiments. The control terminal is electrically connected to the control unit of the downlight, and / or the control terminal interacts with the control unit. Wherein:
[0053] The control terminal can be a conventional control panel (such as a mechanical switch panel), an intelligent control panel, or a remote control. When the control terminal is a conventional control panel, the control terminal is electrically connected to the control unit.
[0054] When the control terminal is an intelligent control panel or a remote control, the control unit is equipped with a first wireless communication module and the control terminal is equipped with a second wireless communication module; the control terminal and the control unit are electrically connected; and / or the first wireless communication module and the second wireless communication module exchange information.
[0055] Furthermore, the control terminal can also be a smart mobile terminal (such as a mobile phone, tablet, smart belt-wearing device, etc.) or an artificial intelligence robot. By setting up the aforementioned downlights, the lighting system allows users to adjust the lighting effect of the downlights by replacing the diffuser or lens themselves, improving the user experience and helping to reduce operating and maintenance costs.
