Description

Technical Field

[0001] This application relates to the field of outdoor lighting technology, specifically to a modular outdoor lighting fixture. Background Technology

[0002] With the diversification of outdoor lighting scenarios, various outdoor lighting fixtures such as courtyard lights, wall lights, pillar lights, and lawn lights are widely used in landscape beautification, public spaces, and family courtyards.

[0003] Lighting source modules, waterproof sealing structures, and connection structures adapted to the installation carrier generally adopt independent customized designs. For each type of lamp, a dedicated light source component needs to be developed. Furthermore, the core components of different types of lamps cannot be interchanged, resulting in a lack of universality among the core components of various types of lamps.

[0004] Therefore, how to break the fixed pairing relationship between lighting components and base components, and achieve flexible adaptation of at least two different base components with the same lighting component through modular design, has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The present invention aims to at least solve the problem in the related art of the fixed pairing relationship between lighting components and base components, and the problem that different types of lamp bases cannot be used for the same lighting component.

[0006] To this end, the first aspect of this utility model provides a modular outdoor lighting fixture, comprising: a lighting component; at least two types of base components; and a connecting component, which can be detachably installed on any one of the at least two types of base components and detachably connected to the lighting component; wherein, the base component includes a base tube, a first mounting structure is provided on the side wall of the base tube, and a second mounting structure is provided on the connecting component, the second mounting structure cooperating with the first mounting structure to enable any base component to be detachably connected to the connecting component.

[0007] This utility model provides a modular outdoor lighting fixture, including a lighting component, at least two types of base components, and a connecting component. The various components cooperate with each other through a detachable structure, thereby achieving flexible adaptation and convenient replacement between the lighting component and different types of base components. Specifically, the at least two types of base components may include a ground light base and a wall light base. The ground light base and the wall light base can be detachably connected to the lighting component. Both the ground light base and the wall light base are provided with a base sleeve, which serves as the main support structure of the base component. Its function is to fix it to the mounting base and provide a stable connection to the components above. The side wall of the base sleeve has a first mounting structure, which can be in the form of a slot, buckle, threaded hole, positioning pin hole, or guide rail, etc. Users select the required type of base component according to the installation scenario; for example, a ground light base for a courtyard walkway and a wall light base for a building exterior wall. The second mounting structure on the connecting component is then fitted and fixed with the first mounting structure on the side wall of the base sleeve, and the lighting component and connecting component are then detachably connected. Alternatively, the lighting component and the connecting component can be connected first, and then the connecting component can be installed on the base component through the second mounting structure. When it's necessary to replace the lighting components or change the installation scenario, simply disconnect the connecting component from the base component to replace the lighting component individually or replace it with a different type of base component, without having to replace the entire luminaire. Compared to existing independently designed outdoor luminaires, the lighting components in this solution are compatible with different types of base components. Users only need to prepare one model of lighting component to install on different base components, which not only reduces the types of parts that need to be stored, but also allows users to replace damaged lighting components themselves by disassembling the connecting component, reducing maintenance difficulty and costs, and avoiding the situation where the entire luminaire is scrapped due to the failure of a single component.

[0008] In some embodiments, the first mounting structure may optionally include at least two guide ribs extending along the axial direction of the base tube, each guide rib having a radial first through hole; the second mounting structure includes a sliding groove that corresponds to and engages with the at least two guide ribs; the modular outdoor luminaire may further include at least two first fasteners, which pass through the first through hole and are pressed against the surface of the connecting component to connect the lighting component and any base component.

[0009] In this embodiment, the base assembly has a first mounting structure on its seat sidewall. The first mounting structure includes at least two guide ribs extending along the seat axis. Multiple guide ribs are symmetrically or evenly distributed around the outer periphery of the seat, thereby guiding the connecting assembly to smoothly slide into a predetermined position along the axial direction of the seat and providing circumferential limiting to prevent rotational displacement of the connecting assembly during installation. Each guide rib has a radial first through hole penetrating the thickness direction of the guide rib, allowing a first fastener to pass through after installation, thereby axially fixing the connecting assembly to the base assembly.

[0010] The connecting component is equipped with a second mounting structure, which includes a sliding groove that corresponds to and engages with at least two guide ribs. The groove shape matches the cross-section of the guide rib, allowing for sliding engagement when the guide rib is inserted and restricting the circumferential movement of the connecting component relative to the base component, thus ensuring the stability of the connecting component and the base in the circumferential direction. The modular outdoor lighting fixture also includes at least two first fasteners. After passing through the first through hole on the guide rib, the first fastener presses its end against the surface of the connecting component, forming an axial lock through elastic pressing, thereby making the lighting component, connecting component, and any base component a strong and detachable whole. Dividing the lighting fixture into three parts—base component, connecting component, and lighting component—is easier for users to operate than the traditional integrated structure. The parts are only connected by plugging and a few fasteners. During disassembly, it is not necessary to completely remove the first fasteners; simply loosening the engagement with the sliding groove is sufficient to disassemble the lighting component. Compared with existing independently designed outdoor lighting fixtures, the guide ribs and sliding grooves in this solution ensure directional accuracy and positional consistency during installation, while the first fasteners restrict the axial movement of the lighting component and the base component. Furthermore, the opposing arrangement of multiple first through holes and multiple first fasteners ensures balanced force distribution, preventing tilting or loosening caused by unilateral locking. Therefore, this application reduces the types of spare parts and maintenance costs, and also avoids the scrapping of the entire lamp due to partial damage, thus saving resources and improving the assembly flexibility of the lamp.

[0011] Optionally, the first fastener may be a screw or a bolt, and the number of them corresponds to the number of guide ribs.

[0012] In some embodiments, the connecting assembly may optionally include a connecting ring, the connecting ring including: an upper ring portion sleeved on a portion of the lighting assembly; a lower ring portion connected to the upper ring portion; a groove disposed on the outer wall of the lower ring portion; and a seat sleeve sleeved on the outer side of the lower ring portion through the cooperation of a guide rib and the groove. The diameter of the lower ring portion is smaller than the diameter of the upper ring portion.

[0013] In this embodiment, the connecting ring includes an upper ring portion and a lower ring portion coaxially arranged. The upper ring portion is annular, and its inner diameter matches a portion of the outer contour of the lighting assembly, allowing it to be fitted onto a designated section of the lighting assembly. The inner wall of the upper ring portion may be provided with a first snap-fit ​​structure, which cooperates with a second snap-fit ​​structure on the lighting assembly to fix the connecting ring onto the lighting assembly.

[0014] The lower ring is connected to the lower end of the upper ring. The diameter of the lower ring is smaller than that of the upper ring, thus providing guiding space for the fitted connection. The outer wall of the lower ring has a groove, which corresponds one-to-one with the guide ribs on the base tube. The base tube can be fitted onto the outside of the lower ring along the extension direction of the groove with the help of the guide ribs, thus forming an insertion fit between the base assembly and the connecting assembly. During installation, first, the upper ring of the connecting ring is fitted onto the corresponding position of the lighting assembly, and the connection and fixation of the two are completed. Then, the lower ring is aligned with the base tube of the base assembly, and the guide ribs on the base tube slide into the groove of the lower ring until the base tube is completely fitted onto the outside of the lower ring. Then, the first fastener passes through the first through hole of the guide rib and is pressed against the outer wall of the lower ring to achieve axial locking. Compared with the ordinary straight cylindrical connecting ring, the lower ring diameter of this solution is smaller, making it easier to align the base tube when fitted. The nested design also improves the connection reliability between the lighting assembly and the base assembly.

[0015] Optionally, the upper ring and the lower ring are integrally formed.

[0016] In some embodiments, the lighting assembly may optionally include a light source module, with a latch and a radial second through hole on the inner wall of the lower ring portion. The connecting assembly may also include a bottom cover base for connecting the light source module, with a locking groove on the outer wall of the bottom cover base, and the locking groove and the latch being detachably connected. The modular outdoor lighting fixture may also include at least two second fasteners, which pass through the second through hole and are pressed against the surface of the bottom cover base to connect the bottom cover base and the connecting ring.

[0017] In this embodiment, the lighting assembly includes a light source module, which is the main body of the lamp that emits light and is fixed to the base. That is, the base serves as both the load-bearing structure for the light source module and the connecting bridge between the lighting assembly and the connecting ring. The inner wall of the lower ring of the connecting ring has a latch and a radial second through hole. The position of the latch corresponds to the locking groove on the outer wall of the base, and the shape of the locking groove matches the latch. The two can achieve a detachable mechanical engagement, thus providing initial positioning and a certain degree of anti-detachment. The modular outdoor lamp also includes at least two second fasteners, the number of which is the same as the number of second through holes. After passing through the second through hole of the lower ring, the second fastener's end presses against the surface of the base. By pressing the base and the connecting ring together, axial fixation is achieved, thereby securely connecting the base and the light source module to the connecting ring. Compared to solutions that rely solely on threaded fastening or snap-fit, this solution combines both locking snap-fit ​​and secondary fastener clamping. Snap-fit ​​provides quick positioning and initial anti-loosening, reducing assembly difficulty, while the fastener provides reliable axial locking, improving assembly strength. The two installation methods complement each other, avoiding both the loosening caused by wear or external impact during long-term use of a single snap-fit ​​and the inconvenience of frequent tightening and disassembly due to relying solely on fasteners.

[0018] In some embodiments, the locking groove may optionally include: a guide groove disposed on the outer wall of the bottom cover base along the axial direction of the seat cylinder; and a limiting groove communicating with the end of the guide groove and extending at an angle to the guide groove. The limiting groove is used to accommodate the latch after it has slid into and rotated through the guide groove, and the side wall of the limiting groove is used to restrict the latch from sliding along the axial direction of the seat cylinder.

[0019] In this embodiment, the locking groove is located on the outer wall of the base cover and consists of a guide groove and a limiting groove. The guide groove extends along the axial direction of the seat cylinder, and its inlet width matches the cross-sectional shape of the latch, allowing the latch to slide smoothly into the axial direction during assembly. The assembly process is intuitive and has high fault tolerance. The limiting groove is connected to the end of the guide groove, and its extension direction forms a certain angle with the guide groove. This angle is preferably an approximate right angle or another angle that effectively prevents axial movement. When the latch slides to the end of the guide groove, rotating the base cover or connecting ring allows the latch to enter the limiting groove. The side wall of the limiting groove blocks the latch, thus restricting further sliding or disengagement along the axial direction of the seat cylinder, achieving rotational locking. Compared to solutions using only a direct-insertion snap-fit ​​or only threaded fastening, this rotational locking structure provides a more defined stop in the axial direction. During installation, the user only needs to push in and rotate once to achieve a secure connection, and during disassembly, simply rotate in the opposite direction and pull out. Therefore, the installation and disassembly of the bottom cover base and connecting ring are relatively simple, making them easy for users to operate and reducing the difficulty of installation and disassembly.

[0020] In some embodiments, the modular outdoor lighting fixture may optionally include: an annular groove, which is disposed around the inner side of the upper ring along the circumferential direction of the connecting ring; and a lower sealing ring, which is disposed in the annular groove and is press-fitted with the bottom cover base and the connecting ring respectively.

[0021] In this embodiment, an annular groove is arranged around the inner side of the upper ring along the circumference of the connecting ring. The lower sealing ring is made of elastic waterproof material and is placed in the annular groove during installation. One side is press-fitted with the groove wall of the connecting ring, and the other side is press-fitted with the outer wall of the bottom cover base, forming a double-contact compression seal, which improves the sealing performance of the lighting component. Even if the outdoor lamp is in a spray, immersion, or high humidity environment, it can effectively prevent liquid intrusion, thereby improving the service life of the light source module.

[0022] In some embodiments, the connecting assembly may optionally include: a bracket assembly detachably disposed on the side of the bottom cover base facing the lighting assembly; a lamp holder detachably connected to the bracket assembly, wherein the light source module is mounted on the lamp holder; the modular outdoor luminaire may also include: a heat sink disposed on the side of the bottom cover base away from the lighting assembly.

[0023] In this embodiment, the connecting assembly further includes a bracket assembly and a lamp holder. The bracket assembly is detachably disposed on the side of the bottom cover base facing the lighting component, serving as a support and positioning structure for the lamp holder and connecting the lamp holder and the bottom cover base into a stable assembly. The modular outdoor lighting fixture also includes a heat sink, which is disposed on the side of the bottom cover base facing away from the lighting component, i.e., opposite to the light source module. The heat sink can be finned or multi-channel ribbed to increase the heat dissipation area. The heat sink is located inside the base, which is in communication with the external environment. The heat sink absorbs heat from the lamp holder through thermally conductive contact with the bottom cover base, and then dissipates the heat to the external environment through natural convection or auxiliary airflow, achieving indirect heat dissipation for the light source module.

[0024] Optionally, the bracket assembly includes a lamp holder bracket and a connecting bracket, both of which are standard parts.

[0025] In some embodiments, the modular outdoor lighting fixture may optionally include: a vent valve located on the side of the base away from the light source module for exchanging gas within the lighting assembly and the base assembly to balance the air pressure; and a waterproof cable passage assembly located on the side of the base away from the light source module and spaced apart from the vent valve, the waterproof cable passage assembly being used to allow cables to pass through and seal the internal space of the lighting assembly.

[0026] In this embodiment, a vent valve and a waterproof cable routing assembly are added to the side of the base of the modular outdoor luminaire facing away from the light source module. This addresses the sealing issues caused by pressure differences between the inside and outside of the luminaire due to changes in ambient temperature and humidity, as well as the sealing problems caused by cable entry points. The vent valve, located on the side of the base facing away from the light source module, balances the gas pressure inside the lighting component and the base assembly during temperature and humidity changes or when the luminaire is switched on and off. This prevents deformation of the sealing structure or condensation due to excessive pressure differences, and also allows for the release of any small amount of heat generated internally, maintaining a stable operating environment for the light source module and drive circuit. The waterproof cable routing assembly is also located on the side of the base facing away from the light source module and is spaced apart from the vent valve to avoid mutual interference. External cables are introduced through the waterproof cable routing assembly, and the sealing structure prevents liquids and dust from penetrating into the lighting component along the cables. Therefore, compared to a sealed structure without a vent valve, this application avoids the problems of internal condensation or seal bulging failure due to temperature changes caused by complete sealing, thus helping to maintain a high level of protection and extend the life of the seal. At the same time, compared to solutions without independent waterproof wiring components, it prevents the vent valve from being affected by moisture along the wiring, improving the reliability of the overall waterproof design.

[0027] In some embodiments, the lighting assembly may optionally include: a top cover; a light-transmitting cover connected to the top cover and the connecting ring respectively, the light source module being located inside the light-transmitting cover, and the light source module being housed within a sealed space formed by the top cover, the light-transmitting cover and the bottom cover base.

[0028] In this embodiment, the lighting assembly further includes a top cover and a light-transmitting cover. The light-transmitting cover is a cylindrical body open at both ends, and the top cover is located on top of the light-transmitting cover. The top cover can be a disc cover or a cover with outward-flaring edges, used to seal the top of the lamp and form the exterior surface. The lower end of the light-transmitting cover is sealed by a bottom cover base. The light-transmitting cover, top cover, and bottom cover base together form a sealed space, isolating the light source module from external water, dust, and pollutants. An upper sealing ring is located between the top cover and the light-transmitting cover. The light source module is located inside the light-transmitting cover. Together with the lower sealing ring at the bottom cover base and the waterproof wiring assembly, the overall protection level is improved. Therefore, the lighting assembly of this application is an independent and sealed light-emitting unit, which can prevent moisture and dust from the outdoor environment from entering the interior of the lighting assembly, and can be quickly opened through snaps and modular connections when maintenance is required, thus balancing protection reliability and maintenance convenience.

[0029] In some embodiments, the base assembly may optionally include a first base, the first base including: a first pedestal including a first mounting hole; a first mounting bracket disposed opposite to the lighting assembly, the first mounting bracket including a second mounting hole; and a third fastener passing through the first mounting hole and the second mounting hole to fix the first pedestal and the first mounting bracket.

[0030] In this embodiment, a first base is used to mount the lamp on the ground, enabling it to be used as a garden lamp. The first base includes a first pedestal and a first mounting bracket. The first pedestal has a first mounting hole, which can be a through hole or a threaded hole. The first mounting bracket is positioned opposite the lighting assembly, located above the first pedestal or facing the lighting assembly. The first mounting bracket has a second mounting hole, and a third fastener passes through both the first and second mounting holes, fixing the first pedestal and the first mounting bracket together. This application separates the first pedestal and the first mounting bracket and connects them via a third fastener, eliminating the need to replace the entire base, thus improving the base's adaptability and maintainability, and also increasing the application range and installation flexibility of the modular outdoor lighting fixture.

[0031] In some embodiments, the base assembly optionally includes a second base, the second base including: a first base; a fixing connector disposed on the outer side wall of the first base, the fixing connector including: a second mounting bracket including a third mounting hole; a second base including a fourth mounting hole; a fourth fastener passing through the third mounting hole and the fourth mounting hole to fix the second base and the second mounting bracket; and a base connector connecting the second base and the first base.

[0032] In this embodiment, the second base is used to mount the lamp on the wall, enabling it to be used as a wall lamp. The second base includes a first base, a second base, a second mounting bracket, and a base connector. The first base cooperates with the connecting component; the first base is also the base sleeve. A first mounting structure is provided on the side wall of the base sleeve for insertion into the sliding groove of the connecting component and locked by a first fastener. The fixing connector is located on the outer side wall of the first base. The second mounting bracket faces the wall mounting position and has a third mounting hole. The second base body has a fourth mounting hole. The fourth fastener passes through the third and fourth mounting holes, fixing the second base and the second mounting bracket together. This design makes the first base and the fixing connector independently fixable to the wall. The separate design of the fixing connector and the base connector allows for replacement or adjustment of only the corresponding components when wall conditions change, without having to replace the entire lamp's connecting and lighting components. Simultaneously, the first base and the fixing connector enable the modular outdoor lamp to be stably installed on a vertical surface in the form of a wall lamp, maintaining the convenience of modular assembly and disassembly.

Detailed Implementation

[0044] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0045] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0046] like Figure 1 and Figure 2 As shown, the first aspect of this utility model provides a modular outdoor lighting fixture 1, including: a lighting component 11; at least two types of base components 12; and a connecting component 13, which can be detachably installed on any one of the at least two types of base components 12 and detachably connected to the lighting component 11; wherein, the base component 12 includes a base 121, a first mounting structure 122 is provided on the side wall of the base 121, and a second mounting structure 131 is provided on the connecting component 13, the second mounting structure 131 cooperating with the first mounting structure 122 to enable any base component 12 to be detachably connected to the connecting component 13.

[0047] The modular outdoor lighting fixture 1 provided by this utility model includes a lighting component 11, at least two types of base components 12, and a connecting component 13. The various components cooperate with each other through a detachable structure, thereby achieving flexible adaptation and convenient replacement between the lighting component 11 and different types of base components 12. Specifically, the at least two types of base components 12 may include a ground light base and a wall light base. The ground light base and the wall light base can be detachably connected to the lighting component 11. Both the ground light base and the wall light base are provided with a base sleeve 121. The base sleeve 121 serves as the main support structure of the base component 12, its function being to fix it to the mounting base and provide a stable connection to the components above. The side wall of the base sleeve 121 is provided with a first mounting structure 122, which can be in the form of a slot, a buckle, a threaded hole, a positioning pin hole, or a guide rail, etc. Users select the required type of base component 12 according to the installation scenario. For example, a ground light base can be selected for a courtyard walkway, and a wall light base can be selected for a building exterior wall. The second mounting structure 131 on the connecting component 13 is then matched and fixed with the first mounting structure 122 on the side wall of the base 121. The lighting component 11 and the connecting component 13 are then detachably connected. Alternatively, the lighting component 11 and the connecting component 13 can be connected first, and then the connecting component 13 can be installed on the base component 12 through the second mounting structure 131. When it is necessary to replace the lighting component 11 or change the installation scenario, it is only necessary to disconnect the connection between the connecting component 13 and the base component 12 to replace the lighting component 11 individually or replace it with another type of base component 12, without replacing the entire lighting fixture. Compared with existing independently designed outdoor lighting fixtures, the lighting component 11 of this solution can be adapted to different types of base components 12. Users only need to prepare one type of lighting component 11 to install on different base components 12. This not only reduces the types of parts that need to be stored, but also allows users to replace the lighting component 11 themselves by disassembling the connecting component 13 when it is damaged, reducing maintenance difficulty and cost, and avoiding the situation where the entire lighting fixture is scrapped due to the damage of a single component.

[0048] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, the first mounting structure 122 includes at least two guide ribs 1221 extending along the axial direction of the base 121, and each guide rib 1221 has a radial first through hole 1222; the second mounting structure 131 includes a sliding groove 1311 that corresponds to and engages with the at least two guide ribs 1221; the modular outdoor lamp 1 also includes at least two first fasteners 14, which pass through the first through hole 1222 and are pressed against the surface of the connecting component 13 to connect the lighting component 11 and any base component 12.

[0049] In this embodiment, a first mounting structure 122 is provided on the side wall of the seat 121 of the base assembly 12. The first mounting structure 122 includes at least two guide ribs 1221 extending along the axial direction of the seat 121. The multiple guide ribs 1221 are symmetrically or evenly distributed on the outer periphery of the seat 121, thereby guiding the connecting assembly 13 to slide smoothly into a predetermined position along the axial direction of the seat 121 and providing circumferential limiting to prevent the connecting assembly 13 from rotating or shifting during installation. Each guide rib 1221 has a radial first through hole 1222 that penetrates the thickness direction of the guide rib 1221, allowing the first fastener 14 to pass through after installation, thereby fixing the connecting assembly 13 to the base assembly 12 in the axial direction.

[0050] The connecting component 13 is provided with a second mounting structure 131, which includes a sliding groove 1311 that corresponds to and engages with at least two guide ribs 1221. The groove shape of the sliding groove 1311 matches the cross-section of the guide rib 1221, allowing for sliding engagement when the guide rib 1221 is inserted, and restricting the circumferential movement of the connecting component 13 relative to the base component 12, thereby ensuring the stability of the connecting component 13 and the base 121 in the circumferential direction. The modular outdoor lighting fixture 1 also includes at least two first fasteners 14. After passing through the first through hole 1222 on the guide rib 1221, the first fastener 14 presses its end against the surface of the connecting component 13, forming an axial lock through elastic pressing, thereby making the lighting component 11, the connecting component 13 and any base component 12 a firm and detachable whole. The luminaire is divided into three parts: a base assembly 12, a connecting assembly 13, and a lighting assembly 11. Compared to the traditional integrated structure, this design is easier for users to operate. The parts are only connected by plug-in joints and a few fasteners. Disassembly does not require completely removing the first fastener 14; simply releasing its contact with the slide groove 1311 allows disassembly of the lighting assembly 11. Compared to existing independently designed outdoor luminaires, the guide rib 1221 and slide groove 1311 in this design ensure directional accuracy and positional consistency during installation. Simultaneously, the first fastener 14 restricts the axial movement of the lighting assembly 11 and the base assembly 12. Furthermore, the opposing arrangement of multiple first through holes 1222 and multiple first fasteners 14 ensures balanced force, preventing tilting or loosening caused by unilateral locking. Therefore, this application reduces the types of spare parts and maintenance costs, and avoids the scrapping of the entire luminaire due to partial damage, thus saving resources and improving the assembly flexibility of the luminaire.

[0051] Optionally, the first fastener 14 may be a screw or a bolt, and the number of them corresponds to the number of guide ribs 1221.

[0052] In some embodiments, optionally, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connecting assembly 13 includes a connecting ring 132, which includes an upper ring portion 1321, sleeved on a portion of the lighting assembly 11; a lower ring portion 1322, connected to the upper ring portion 1321; a sliding groove 1311 is provided on the outer wall of the lower ring portion 1322; and a seat cylinder 121 is sleeved on the outside of the lower ring portion 1322 through the cooperation of the guide rib 1221 and the sliding groove 1311. The diameter of the lower ring portion 1322 is smaller than the diameter of the upper ring portion 1321.

[0053] In this embodiment, the connecting ring 132 includes an upper ring portion 1321 and a lower ring portion 1322 coaxially arranged. The upper ring portion 1321 is annular, and its inner diameter matches a portion of the outer contour of the lighting assembly 11, allowing it to be fitted onto a designated section of the lighting assembly 11. The inner wall of the upper ring portion 1321 may be provided with a first snap-fit ​​structure, which cooperates with a second snap-fit ​​structure on the lighting assembly 11 to fix the connecting ring 132 onto the lighting assembly 11.

[0054] The lower ring portion 1322 is connected to the lower end of the upper ring portion 1321. The diameter of the lower ring portion 1322 is smaller than that of the upper ring portion 1321, thereby providing guiding space for the sleeved connection. The outer wall of the lower ring portion 1322 is provided with a sliding groove 1311, which corresponds one-to-one with the guide ribs 1221 on the seat cylinder 121. The seat cylinder 121 can be sleeved on the outside of the lower ring portion 1322 along the extending direction of the sliding groove 1311 with the help of the guide ribs 1221, thereby forming an insertion fit between the base assembly 12 and the connecting assembly 13. During installation, first, the upper ring portion 1321 of the connecting ring 132 is fitted onto the corresponding position of the lighting assembly 11, and the connection and fixation of the two are completed. Then, the lower ring portion 1322 is aligned with the seat cylinder 121 of the base assembly 12, so that the guide rib 1221 on the seat cylinder 121 slides into the groove 1311 of the lower ring portion 1322 until the seat cylinder 121 is completely fitted onto the outside of the lower ring portion 1322. Subsequently, the first fastener 14 passes through the first through hole 1222 of the guide rib 1221 and is pressed against the outer wall of the lower ring portion 1322 to achieve axial locking. Compared with the ordinary straight cylindrical connecting ring, the lower ring portion 1322 of this solution has a smaller diameter, making it easier to align the seat cylinder 121 when it is fitted. The nested design also improves the connection reliability between the lighting assembly 11 and the base assembly 12.

[0055] Optionally, the upper ring portion 1321 and the lower ring portion 1322 are integrally formed.

[0056] In some embodiments, optionally, such as Figure 1 , Figure 3 and Figure 4As shown, the lighting assembly 11 includes a light source module 111, and a latch 1323 and a radial second through hole 1324 are provided on the inner wall of the lower ring portion 1322. The connecting assembly 13 also includes a bottom cover base 133, which connects to the light source module 111. A locking groove 1332 is provided on the outer wall of the bottom cover base 133, and the locking groove 1332 and the latch 1323 are detachably connected. The modular outdoor lamp 1 also includes at least two second fasteners 15. After the second fasteners 15 pass through the second through hole 1324, they are pressed against the surface of the bottom cover base 133 to connect the bottom cover base 133 and the connecting ring 132.

[0057] In this embodiment, the lighting assembly 11 includes a light source module 111, which is the main body for emitting light and is fixed to the bottom cover base 133. That is, the bottom cover base 133 serves as both the supporting structure for the light source module 111 and the connecting bridge between the lighting assembly 11 and the connecting ring 132. The inner wall of the lower ring portion 1322 of the connecting ring 132 is provided with a latch 1323 and a radial second through hole 1324. The position of the latch 1323 corresponds to the locking groove 1332 on the outer wall of the bottom cover base 133, and the shape of the locking groove 1332 matches the latch 1323. The two can achieve a detachable mechanical engagement, thereby providing initial positioning and a certain degree of anti-detachment function. The modular outdoor lighting fixture 1 also includes at least two second fasteners 15, the number of which is the same as the number of second through holes 1324. After the second fastener 15 passes through the second through hole 1324 of the lower ring 1322, its end presses against the surface of the bottom cover base 133. By pressing the bottom cover base 133 and the connecting ring 132 together, axial fixation is achieved, thereby firmly connecting the bottom cover base 133 and the light source module 111 to the connecting ring 132. Compared with solutions that only use threaded fastening or only rely on snap-fit, this solution combines the snap-fit ​​of the latch 1323 and the pressing of the second fastener 15. The snap-fit ​​provides quick positioning and initial anti-dislodgement, reducing assembly difficulty, while the fastener provides reliable axial locking, improving the firmness of the assembly. The two installation methods complement each other, avoiding both the loosening caused by wear or external impact during long-term use of a single snap-fit ​​and the inconvenience of frequent tightening and disassembly caused by relying solely on fasteners.

[0058] In some embodiments, optionally, such as Figure 1 , Figure 5 and Figure 6 As shown, the lock groove 1332 includes: a guide groove 1333, which is disposed on the outer wall of the bottom cover base 133 along the axial direction of the seat 121; and a limiting groove 1334, which communicates with the end of the guide groove 1333 and extends at an angle to the guide groove 1333. The limiting groove 1334 is used to accommodate the latch 1323 after it has slid into and rotated through the guide groove 1333. The side wall of the limiting groove 1334 is used to restrict the latch 1323 from sliding along the axial direction of the seat 121.

[0059] In this embodiment, the locking groove 1332 is located on the outer wall of the bottom cover base 133 and consists of a guide groove 1333 and a limiting groove 1334. The guide groove 1333 extends along the axial direction of the seat cylinder 121, and its inlet width matches the cross-sectional shape of the latch 1323, allowing the latch 1323 to slide smoothly into the axial direction during assembly. The assembly process is intuitive and has high tolerance for errors. The limiting groove 1334 is connected to the end of the guide groove 1333, and its extension direction forms a certain angle with the guide groove 1333. Preferably, the angle is an approximate right angle or other angle that effectively prevents axial movement. After the latch 1323 slides to the end along the guide groove 1333, the latch 1323 enters the limiting groove 1334 by rotating the bottom cover base 133 or the connecting ring 132. The side wall of the limiting groove 1334 will block the latch 1323, thereby restricting the latch 1323 from continuing to slide or disengage along the axis of the seat 121, thus achieving rotational locking. Compared with solutions that only use direct insertion or threaded fastening, the rotational locking structure of this solution provides a clearer stop in the axial direction. During installation, the user only needs to push in and rotate once to achieve a stable connection, and during disassembly, it is only necessary to rotate in the opposite direction and pull out. Therefore, the installation and disassembly of the bottom cover base 133 and the connecting ring 132 are relatively simple, convenient for users, and reduce the difficulty of installation and disassembly.

[0060] In some embodiments, optionally, such as Figure 1 , Figure 3 and Figure 4 As shown, the modular outdoor lighting fixture 1 also includes: an annular groove 1325, which is arranged around the inner side of the upper ring 1321 along the circumferential direction of the connecting ring 132; and a lower sealing ring 16, which is disposed in the annular groove 1325 and is interference-fitted with the bottom cover base 133 and the connecting ring 132 respectively.

[0061] In this embodiment, the annular groove 1325 is arranged around the inner side of the upper ring 1321 along the circumferential direction of the connecting ring 132. The lower sealing ring 16 is made of elastic waterproof material and is placed in the annular groove 1325 during installation. One side is press-fitted with the groove wall of the connecting ring 132, and the other side is press-fitted with the outer wall of the bottom cover base 133, forming a double contact surface compression seal, which improves the sealing performance of the lighting component 11. Even if the outdoor lamp is in a spray, immersion or high humidity environment, it can effectively prevent liquid intrusion, thereby improving the service life of the light source module 111.

[0062] In some embodiments, optionally, such as Figure 1As shown, the connecting component 13 also includes: a bracket assembly 134, which is detachably disposed on the side of the bottom cover base 133 facing the lighting component 11; a lamp holder 135, which is detachably connected to the bracket assembly 134, and the light source module 111 is mounted on the lamp holder 135; the modular outdoor lamp 1 also includes: a heat sink 17, which is disposed on the side of the bottom cover base 133 facing away from the lighting component 11.

[0063] In this embodiment, the connecting assembly 13 further includes a bracket assembly 134 and a lamp holder 135. The bracket assembly 134 is detachably disposed on the side of the bottom cover base 133 facing the lighting assembly 11, serving as a support and positioning structure for the lamp holder 135, and connecting the lamp holder 135 and the bottom cover base 133 into a stable assembly. The modular outdoor lighting fixture 1 also includes a heat sink 17, which is disposed on the side of the bottom cover base 133 facing away from the lighting assembly 11, i.e., in the opposite direction to the light source module 111. The heat sink 17 can be finned or multi-channel ribbed to increase the heat dissipation area. The heat sink 17 is located inside the base 121, which is in communication with the external environment. The heat sink 17 absorbs the heat transmitted from the lamp holder 135 through thermally conductive contact with the bottom cover base 133, and then dissipates the heat to the external environment through natural convection or auxiliary airflow, thereby achieving indirect heat dissipation for the light source module 111.

[0064] Optionally, the bracket assembly 134 includes a lamp holder 135 bracket and a connecting bracket, both of which are standard parts.

[0065] In some embodiments, optionally, such as Figure 1 and Figure 4 As shown, the modular outdoor lighting fixture 1 also includes: a vent valve 18, located on the side of the bottom cover base 133 facing away from the light source module 111, for exchanging gas in the lighting component 11 and the base assembly 12 to balance the air pressure; and a waterproof cable passage assembly 19, located on the side of the bottom cover base 133 facing away from the light source module 111 and spaced apart from the vent valve 18, for allowing cables to pass through and sealing the internal space of the lighting component 11.

[0066] In this embodiment, a vent valve 18 and a waterproof cable guide assembly 19 are added to the side of the base 133 facing away from the light source module 111 to solve the sealing problems caused by the pressure difference between the inside and outside of the modular outdoor light fixture 1 due to changes in ambient temperature and humidity, as well as the sealing problems caused by the cable inlet. The vent valve 18 is located on the side of the base 133 facing away from the light source module 111. Its function is to balance the gas pressure inside the lighting component 11 and the base assembly 12 during ambient temperature rises and falls, humidity changes, or when the light fixture is switched on and off. This prevents deformation of the sealing structure or condensation due to excessive pressure difference, and also allows for the release of any small amount of heat that may be generated inside, maintaining a stable working environment for the light source module 111 and the drive circuit. The waterproof cable guide assembly 19 is also located on the side of the base 133 facing away from the light source module 111 and is spaced apart from the vent valve 18 to avoid mutual interference. External cables are introduced through the waterproof cable guide assembly 19, and the sealing structure prevents liquids and dust from penetrating into the lighting component 11 along the cables. Therefore, compared to a sealed structure without a vent valve, this application avoids the problems of internal condensation or seal bulging failure due to temperature changes caused by complete sealing, thus helping to maintain a high level of protection and extend the life of the seal. At the same time, compared to solutions without independent waterproof wiring components, it prevents the vent valve 18 from being affected by moisture along the wiring, improving the reliability of the overall waterproof design.

[0067] In some embodiments, optionally, such as Figure 1 As shown, the lighting assembly 11 also includes: a top cover 112; a light-transmitting cover 113, which is connected to the top cover 112 and the connecting ring 132 respectively, and the light source module 111 is located inside the light-transmitting cover 113; and an upper sealing ring 114, which is disposed between the top cover 112 and the light-transmitting cover 113, and the light source module 111 is housed in a sealed space formed by the top cover 112, the light-transmitting cover 113 and the bottom cover base 133.

[0068] In this embodiment, the lighting assembly 11 further includes a top cover 112 and a light-transmitting cover 113. The light-transmitting cover 113 is a cylindrical body with openings at both ends. The top cover 112 is located on top of the light-transmitting cover 113. The top cover 112 can be a disc cover or a cover with outward-flaring edges, used to close the top of the lamp and form the exterior surface. The lower end of the light-transmitting cover 113 is sealed by a bottom cover base 133. The light-transmitting cover 113, the top cover 112, and the bottom cover base 133 together form a sealed space, isolating the light source module 111 from external water, dust, and pollutants. An upper sealing ring 114 is located between the top cover 112 and the light-transmitting cover 113. The light source module 111 is located inside the light-transmitting cover 113. Together with the lower sealing ring 16 at the bottom cover base 133 and the waterproof wiring assembly 19, the overall protection level is improved. Therefore, the lighting component 11 of this application is an independent and sealed light-emitting unit, which can prevent moisture and dust in the outdoor environment from entering the interior of the lighting component 11, and can be quickly opened through the snap-fit ​​and modular connection when maintenance is required, thus taking into account both protection reliability and maintenance convenience.

[0069] In some embodiments, optionally, such as Figure 1 and Figure 7 As shown, the base assembly 12 includes a first base 123, which includes: a first base 124 including a first mounting hole 1241; a first mounting bracket 125 disposed opposite to the lighting assembly 11, the first mounting bracket 125 including a second mounting hole 1251; and a third fastener 126 passing through the first mounting hole 1241 and the second mounting hole 1251 to fix the first base 124 and the first mounting bracket 125.

[0070] In this embodiment, the first base 123 is used to install the lamp on the ground, enabling the lamp to be used as a garden lamp. The first base 123 includes a first base 124 and a first mounting bracket 125. The first base 124 has a first mounting hole 1241, which can be a through hole or a threaded hole. The first mounting bracket 125 is disposed opposite to the lighting component 11, located above the first base 124 or on the side facing the lighting component 11. The first mounting bracket 125 has a second mounting hole 1251, and a third fastener 126 passes through the first mounting hole 1241 and the second mounting hole 1251, fixing the first base 124 and the first mounting bracket 125 together. This application separates the first base 124 and the first mounting bracket 125 and connects them through the third fastener 126, eliminating the need to replace the entire base, improving the adaptability and maintainability of the base, and also increasing the application range and installation flexibility of the modular outdoor lamp 1.

[0071] In some embodiments, optionally, such as Figure 2 , Figure 8 and Figure 9As shown, the base assembly 12 includes a second base 128, which includes: a first base 124; a fixing connector 127 disposed on the outer side wall of the first base 124, the fixing connector 127 including: a second mounting bracket 1271 including a third mounting hole 1272; a second base 1273 including a fourth mounting hole 1274; a fourth fastener 1275 passing through the third mounting hole 1272 and the fourth mounting hole 1274 to fix the second base 1273 and the second mounting bracket 1271; and a base connector 1276 connecting the second base 1273 and the first base 124.

[0072] In this embodiment, the second base 128 is a wall lamp base, used to install the lamp on the wall, allowing the lamp to be used as a wall lamp. The second base 128 includes a first base 124, a second base 1273, a second mounting bracket 1271, and a base connector 1276. The first base 124 cooperates with the connecting assembly 13. The first base 124 is also known as the seat 121. The side wall of the seat 121 is provided with a first mounting structure 122 for insertion into the sliding groove 1311 of the connecting assembly 13 and locked by a first fastener 14. The fixing connector 127 is provided on the outer side wall of the first base 124. The second mounting bracket 1271 faces the wall mounting position and has a third mounting hole 1272. The second base 1273 has a fourth mounting hole 1274 on its body. The fourth fastener 1275 passes through the third mounting hole 1272 and the fourth mounting hole 1274, fixing the second base 1273 and the second mounting bracket 1271 together. This design makes the first base 124 and the fixing connector 127 independently fixable to the wall. The separate design of the fixing connector 127 and the base connector 1276 allows for replacement or adjustment of only the corresponding components when wall conditions change, without needing to replace the entire lamp's connecting assembly 13 and lighting assembly 11. Simultaneously, the first base 124 and the fixing connector 127 enable the modular outdoor lamp 1 to be stably installed on a vertical surface in the form of a wall lamp, maintaining the convenience of modular assembly and disassembly.

[0073] In a specific application, such as Figures 1 to 9 As shown, the modular outdoor lighting fixture 1 includes a lighting component 11, a garden light base (first base 123) and a wall light base (second base 128).

[0074] The lighting assembly 11 includes a bowl-shaped base 133. A bracket assembly 134 is provided on one side of the base 133. The bracket assembly includes a mounting bracket and a lamp holder fixing bracket. The mounting bracket is fixed to the base 133 with screws. The lamp holder fixing bracket is fixed to the mounting bracket with screws.

[0075] Two pairs of slots (locking slots 1332) are provided on the back of the base 133 of the bottom cover. A buckle (buckle 1323) matching the slot is provided on the mating surface of the middle ring (connecting ring 132) of the bottom cover. The slot of the lighting assembly is aligned with the buckle on the middle ring of the bottom cover and pushed in. Then, by rotating it a certain angle, the buckle slides into the locking position of the slot, achieving mechanical fixation. The screw (second fastener 15) is aligned with the screw hole (second through hole 1324) to achieve a second locking, preventing the middle ring of the bottom cover from loosening from the base 133 of the bottom cover.

[0076] An annular groove 1325 is provided on the mating surface of the bottom cover ring, and a waterproof sealing ring (lower sealing ring 16) is embedded therein. When the lighting assembly 11 is rotated and locked, the back of the bottom cover base 133 will compress the lower sealing ring 16 to form a reliable waterproof barrier.

[0077] like Figure 7 and Figure 8 As shown, the same lighting component 11 is connected to both the wall lamp base and the courtyard lamp base, wherein, as Figure 1 As shown, the anti-foolproof strip (guide rib 1221) and the anti-foolproof groove (slide groove 1311) are interlocked and secured with screws (first fastener 14). The installation method of the garden light base is exactly the same.

[0078] Figure 3 and Figure 4 The demonstration shows how to remove the lighting assembly 11. First, loosen the screw (second fastener 15) from the screw hole (second fastener 15), then rotate the lighting assembly 11 counterclockwise to remove it, and finally remove the old light source module and connect the new light source module to achieve quick replacement.
