Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to a power supply device and system. Background Technology

[0002] In the current LED lighting field, LED luminaires have been widely used in numerous scenarios such as commercial lighting, home lighting, and landscape lighting due to their significant advantages such as high efficiency, energy saving, long lifespan, and rich colors. With the rapid development of IoT technology and the increasing demand for intelligent lighting, remote control and management of LED luminaires, such as remote dimming and color adjustment, timed switching, on-demand lighting, digital management and control, and predictive maintenance, has become an important trend in market development.

[0003] In the development of the outdoor LED lighting market, traditional LED power supplies have adopted a separate design architecture for the power module and control module, each housed in a separate enclosure. One enclosure houses a dimmable power supply, while the other houses a remote lighting controller. These two components work together to achieve remote control and management of the LED lights. However, this approach has significant drawbacks: from a cost perspective, the presence of a separate controller increases costs associated with raw material procurement, production assembly, packaging, and transportation; in terms of installation, the two separate enclosures require more installation space, and the wiring connections are cumbersome, demanding a higher level of technical expertise from installers; during maintenance, the separation of modules increases the difficulty of troubleshooting and repair, resulting in longer maintenance cycles and higher costs. Therefore, this approach is gradually being phased out of the market.

[0004] To overcome the drawbacks of traditional designs, intelligent integrated power supplies have emerged in the market. These power supplies integrate the power module and control module onto the same PCB board and house them in the same casing, simplifying the product structure, reducing installation space requirements and maintenance complexity, and to some extent solving the problems of high cost and difficult installation and maintenance associated with traditional solutions. However, this integrated design also brings new technical challenges.

[0005] During operation, the power module generates a significant amount of heat due to its power conversion characteristics, causing the operating temperature of the control module area to rise significantly, exceeding the upper limit of the operating temperature of commonly used control modules on the market. Key components in the control module, such as the wireless communication chip, are extremely sensitive to temperature. High temperatures severely affect their wireless communication performance, causing problems such as unstable signal transmission, delayed or lost control commands, and frequent device disconnections, significantly reducing product stability. Furthermore, prolonged exposure to high temperatures accelerates the aging of electronic components, shortens product lifespan, and increases after-sales maintenance costs. More importantly, the high-temperature operating environment generated by the power module conflicts with the normal-temperature operating conditions required by the control module. Adding heat dissipation devices or temperature control systems to meet these differing needs would further increase product costs, reduce cost-effectiveness, and impact market competitiveness and performance.

[0006] In summary, designing a power supply device and system that can effectively isolate the power supply module and the control module, and prevent the high temperature generated by the power supply module from affecting the operation of the control module, has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide a power supply device and system to solve the problem of mutual interference between power supply modules and control modules that coexist in the same space in the prior art.

[0008] To achieve the above objectives, this utility model provides the following solution:

[0009] This utility model provides a power supply device, including a power supply housing, the interior of which forms a first hollow cavity, and the interior of the first hollow cavity is provided with a power supply module and a control housing. The power supply module includes a power supply PCB circuit board and a main heat-generating device, and the main heat-generating device is arranged away from the control housing.

[0010] The control housing has a second hollow cavity inside, and a control module is placed inside the second hollow cavity. The control module includes a control PCB circuit board, and the power PCB circuit board and the control PCB circuit board are electrically connected and independent of each other.

[0011] In one embodiment, the area within the first hollow cavity used to house the power module is filled with potting compound, while the second hollow cavity is not filled with potting compound, forming an air gap.

[0012] In one embodiment, the power supply housing includes a power supply housing body and at least one housing end cap covering the power supply housing body. A first mounting hole is provided on one end face of the power supply housing body covering the housing end cap. A second mounting hole is provided on the housing end cap corresponding to the end face with the first mounting hole. A screw passing through the second mounting hole is fixed in the first mounting hole. A grounding wire electrically connected to the power supply PCB circuit board is provided at the end face with the first mounting hole. The screw abuts against the grounding wire.

[0013] In one embodiment, a mounting groove is formed on the end face where the first mounting hole is formed. The region of the mounting groove extending axially along the first mounting hole is connected to the first mounting hole. The grounding wire is inserted into the region of the mounting groove extending axially along the first mounting hole and abuts against the portion of the screw extending axially along the first mounting hole.

[0014] In one embodiment, the control housing includes a control housing body, a housing end cap, and a control end cap, wherein the housing end cap and the control end cap are detachably connected to the control housing body.

[0015] In one embodiment, an independent integrated antenna is also included, one end of which is electrically connected to the control PCB circuit board, and the other end extends to the outside of the power supply housing and is connected to the lamp housing.

[0016] In one embodiment, the independent integrated antenna includes an antenna connecting line, a guard coil, and an antenna housing with an internal antenna body. One end of the antenna connecting line is electrically connected to the control PCB circuit board, and the other end is electrically connected to the antenna body. The guard coil is sleeved on the antenna connecting line. A first through hole is provided on the end cap of the housing that makes up the control housing. The guard coil is installed in the first through hole and is sealed to the first through hole. The antenna housing is located outside the power supply housing and is connected to the lamp housing.

[0017] In one embodiment, the antenna connection line and the protective coil are integrally injection molded.

[0018] In one embodiment, the antenna housing is provided with a slot and / or double-sided adhesive, and the slot and / or the double-sided adhesive are respectively connected to the lamp housing.

[0019] This utility model also provides a power supply system, including a light source and the power supply device, wherein the light source is electrically connected to the power supply device.

[0020] The present invention achieves the following technical advantages over the prior art:

[0021] 1. Independent Partition Design: The power module and control module are placed in the first hollow cavity and the second hollow cavity respectively. The heat dissipated by the main heat-generating components of the power module during operation is efficiently dissipated primarily through the first hollow cavity and the power module housing. Simultaneously, the control housing isolates and prevents heat dissipated by the power module from entering the second hollow cavity. This physical isolation shields the power module from heat and electromagnetic interference. This independent partition design effectively avoids mutual interference between the high temperatures caused by the main heat-generating components of the power module and the control module, which requires low-temperature operation. This ensures the control module remains in a stable operating state, significantly improving product stability and lifespan.

[0022] The other technical solutions of this utility model have achieved the following technical effects compared with the prior art:

[0023] 2. Enhanced Heat Dissipation and Insulation: During operation, the heat generated by the main heat-generating components of the power module is efficiently dissipated through the potting compound filling the first hollow cavity and the metal outer casing. The potting compound has excellent thermal conductivity, rapidly transferring heat to the metal casing, which then dissipates it into the surrounding environment. Simultaneously, the second hollow cavity acts as an air-insulated cavity. Air, with its relatively low thermal conductivity, prevents heat generated by the main heat-generating components from being conducted to the control module area through the air within the second hollow cavity. The first hollow cavity, where the power module is housed, is filled with potting compound, while the second hollow cavity remains unfilled. This effectively dissipates the high temperatures generated by the main heat-generating components of the power module and prevents high-temperature radiation from reaching the second hollow cavity, where the control module requires a low-temperature operating environment. This ensures the control module remains in a stable operating state, significantly improving the product's operational stability and lifespan.

[0024] 3. Simplified assembly structure: The design of the mounting slot allows the grounding wire to be fixed to the end face of the power supply housing body while the screws are fixing the end cover of the housing. The screw located in the first mounting hole is in close contact with the grounding wire in the mounting slot, realizing grounding conduction. No additional grounding parts are required, which further reduces the cost of parts and the difficulty of assembly.

[0025] 4. Low-cost antenna design: A standalone integrated antenna replaces the traditional SMA adapter and SMA connector antenna combination, reducing assembly complexity and product cost. The antenna connection components are attached to the lamp housing via slots and double-sided adhesive, facilitating installation. Traditional SMA adapter and SMA connector antenna combinations are relatively complex, requiring the assembly and connection of multiple components, increasing assembly difficulty and time costs, and resulting in higher product costs due to the large number of parts. The standalone integrated antenna combines the antenna body, guard coil, and other components, reducing the number of parts and lowering assembly difficulty and product cost.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1 to 4 As shown, this embodiment provides a power supply device, including a power supply housing 10. A first hollow cavity 11 is formed inside the power supply housing 10. A power module 12 and a control housing 20 are disposed inside the first hollow cavity 11. The power module 12 includes a power PCB circuit board 121 and a main heat-generating device 122. The main heat-generating device 122 is arranged away from the control housing 20. A second hollow cavity 21 is formed inside the control housing 20. A control module 22 is placed inside the second hollow cavity 21. The control module 22 includes a control PCB circuit board 221. The power PCB circuit board 121 and the control PCB circuit board 221 are electrically connected and independent of each other.

[0041] It is understandable that by creating a control housing 20 with a second hollow cavity 21 inside the first hollow cavity 11, the requirements for product miniaturization are met. This achieves the division of the internal space of the power supply housing 10, giving both the power module 12 and the control module 22 independent spaces. Furthermore, the main heat-generating components 122 of the power module 12 are kept away from the control housing 20, ensuring that both the power module 12 and the control module 22 are in suitable working environments. This prevents heat radiation from the main heat-generating components 122 from radiating onto the control PCB circuit board 221, thus affecting the operation of the control module 22. It should be noted that the power PCB circuit board 121 contains multiple electrical components 123, not just the main heat-generating component 122.

[0042] In some specific embodiments, the area within the first hollow cavity 11 used to house the power module 12 is filled with potting compound, while the second hollow cavity 21 is not filled with potting compound, forming an air gap. Heat emitted by the main heat-generating device 122 and other electrical components 123 is conducted to the power housing 10 through the potting compound and then dissipated into the air through the power housing 10. To improve heat dissipation, the power housing body 13, which constitutes the power housing 10, is preferably made of metal. The air in the air gap has a lower heat transfer coefficient than the potting compound, effectively isolating the heat radiation generated by the main heat-generating device 122 and other electrical components 123, and preventing high temperatures from affecting the operation of the control module 22.

[0043] Regarding the grounding design of the power supply PCB circuit board 121, the traditional approach is to assemble the nuts on the end cap and then use an electric screwdriver to install screws to tighten the grounding pads or grounding springs, thereby achieving grounding of the power supply PCB circuit board 121. This method not only increases the labor costs in the power supply assembly process but also requires additional nuts, grounding pads, or grounding springs, further increasing the component costs.

[0044] like Figures 5 to 8 As shown, in some specific embodiments, the power supply housing 10 includes a power supply housing body 13 and at least one housing end cap covering the power supply housing body 13. A first mounting hole 131 is formed on one end face of the power supply housing body 13 with the housing end cap, and a second mounting hole 141 is formed on the housing end cap corresponding to the end face with the first mounting hole 131. A screw 16 passing through the second mounting hole 141 is fixed in the first mounting hole 131. A grounding wire 15 electrically connected to the power supply PCB circuit board 121 is provided at the end face with the first mounting hole 131, and the screw 16 abuts against the grounding wire 15. The grounding wire 15 is fixed at the position where it abuts against the screw 16 by the tight fit between the housing end cap and the end face of the power supply housing body 13 with the first mounting hole 131, and the grounding of the power supply PCB circuit board 121 is achieved by the abutment between the screw 16 and the grounding wire 15.

[0045] In addition, for ease of use, a second through hole 143 is provided on the end cap of the housing. The second through hole 143 is used for the wires electrically connected to the power PCB circuit board 121 to pass through. To increase the sealing performance, a sealing element can be provided on the second through hole 143. The sealing element has a central hole for the wires to pass through, and the edge of the sealing element is used to seal the second through hole 143. Slots 133 located on the same horizontal plane are provided on the two inner side walls of the power housing body 13, which are opposite to each other. The power PCB circuit board 121 is inserted into the slots 133 to prevent the power PCB circuit board 121 from shaking in the first hollow cavity 11. A sealing element is provided between the end cap of the housing and the end face of the power housing body 13 to prevent potting compound from overflowing out of the power housing body 13 when injected into the area of ​​the first hollow cavity 11 for placing the power module 12.

[0046] In some specific embodiments, a mounting groove 132 is formed on the end face where the first mounting hole 131 is provided. The area of ​​the mounting groove 132 extending axially along the first mounting hole 131 is connected to the first mounting hole 131. The grounding wire 15 is inserted into the area of ​​the mounting groove 132 extending axially along the first mounting hole 131 and abuts against the portion of the screw 16 extending axially along the first mounting hole 131. By adding the mounting groove 132 connected to the first mounting hole 131, the contact area between the screw 16 and the grounding wire 15 is increased, thereby improving grounding reliability.

[0047] It should be noted that the power supply housing 10, including the power supply housing body 13 and at least one housing end cover fitted onto the power supply housing body 13, can have several configurations. For example, in configuration one, when the power supply housing 10 includes the power supply housing body 13 and a housing end cover fitted onto the power supply housing body 13, the housing end cover forms part of the control housing 20, and this housing end cover is referred to as housing end cover A14. The other end of the power supply housing body 13 is a closed structure. A first sealing element 17 is provided between the housing end cover A14 and the end face of the power supply housing body 13. The first sealing element 17 is to prevent potting compound from overflowing out of the power supply housing body 13 through the gap between the housing end cover A14 and the end face of the power supply housing body 13 when it is injected into the area of ​​the first hollow cavity 11 used to place the power module 12. In configuration two, when there is no mounting groove 132 on the end face of the power supply housing body 13, the grounding wire 15 is located on the end face of the power supply housing body 13 and abuts against a screw 16 to achieve grounding of the power supply PCB circuit board 121. When there is a mounting groove 132 on the end face of the power supply housing 13, the grounding wire 15 is inserted into the area of ​​the mounting groove 132 extending axially along the first mounting hole 131, and abuts against the portion of the screw 16 extending axially along the first mounting hole 131 to achieve grounding of the power supply PCB circuit board 121.

[0048] In scenario two, when the power supply housing 10 includes a power supply housing body 13 and housing end caps covering both ends of the power supply housing body 13, the housing end cap covering the front end of the power supply housing body 13 is housing end cap B19, and the housing end cap covering the rear end of the power supply housing body 13 and forming part of the control housing 20 is housing end cap A14. A second sealing element 18 is provided between the housing end cap B19 and the end face of the power supply housing body 13. The second sealing element 18 is to prevent potting compound from overflowing out of the power supply housing body 13 through the gap between the housing end cap B19 and the front end face of the power supply housing body 13 when it is injected into the area of ​​the first hollow cavity 11 used to place the power module 12. A first sealing element 17 is provided between the housing end cap A14 and the end face of the power supply housing body 13. The first sealing element 17 is to prevent potting compound from overflowing out of the power supply housing body 13 through the gap between the housing end cap A14 and the rear end face of the power supply housing body 13 when it is injected into the area of ​​the first hollow cavity 11 used to place the power module 12. In scenario two, when there is no mounting groove 132 on the end face of the power supply housing 13, the grounding wire 15 is located on the end face of the power supply housing 13 (which can be the rear end face of the power supply housing 13 corresponding to end cover A14, or the front end face of the power supply housing 13 corresponding to end cover B19), and abuts against a screw 16 to ground the power supply PCB circuit board 121. When there is a mounting groove 132 on the end face of the power supply housing 13, the grounding wire 15 is inserted into the area of ​​the mounting groove 132 (which can be located on the rear end face of the power supply housing 13 corresponding to end cover A14, or the front end face of the power supply housing 13 corresponding to end cover B19) extending axially along the first mounting hole 131, and abuts against the portion of the screw 16 extending axially along the first mounting hole 131 to ground the power supply PCB circuit board 121. The "front end" mentioned in the text refers to... Figure 3 , Figure 4 The left end face of the power supply housing 13 (i.e., the end without the independent integrated antenna 30 in the figure), the rear end refers to Figure 3 , Figure 4 The right end face of the power supply housing 13 (i.e. the end where the independent integrated antenna 30 is set in the figure), and the front and rear ends are similar in the following text.

[0049] In both of the above cases, the housing end caps A14 and B19 can be provided with a second mounting hole 141 and a second through hole 143. Of course, if the power supply housing body 13 has more than two ports, a corresponding number of housing end caps need to be provided according to the number of ports. The housing end caps can be provided with a second mounting hole 141 and a second through hole 143 as needed.

[0050] In some specific embodiments, the control housing 20 includes a control housing body, a housing end cap, and a control end cap 23, which are detachably connected to the control housing body. The control housing 20 and the power housing 10 share a housing end cap, which is the housing end cap A14 in the two cases described above. This eliminates the need for connecting parts to fix the position of the control housing 20, saving costs. The control housing body is an open-end housing. The housing end cap A14 covers one end face of the control housing body, and the control end cap 23 covers the other end face. The internal space is a second hollow cavity 21.

[0051] Combination Figure 5 , Figure 7 It is understood that the control housing body may include a housing wall 144 circumferentially fixed to the housing end cover A14 and a control wall 233 circumferentially fixed to the control end cover 23. The housing end cover A14 and the housing wall 144 may be integrally formed, and the control end cover 23 and the control wall 233 may be integrally formed. The housing wall 144 and the control wall 233 are detachably connected and connected together. The internal space is a second hollow cavity 21.

[0052] For ease of use, the control end cover 23 mentioned above may be provided with a first clearance space 231 and a second clearance space 232. The first clearance space 231 is used to connect the first hollow cavity 11 and the second hollow cavity 21, facilitating the electrical connection of the ribbon cable 222 on the control PCB circuit board 221 to the power PCB circuit board 121. The second clearance space 232 is used for the wires electrically connected to the power PCB circuit board 121. The control end cover 23 is preferably designed in a convex shape.

[0053] The traditional combination of SMA adapters and SMA connector antennas is costly due to its complex structure and numerous components, which hinders product cost control and market promotion.

[0054] like Figure 7As shown, in some specific embodiments, an independent integrated antenna 30 is also included. One end of the independent integrated antenna 30 is electrically connected to the control PCB circuit board 221, and the other end extends to the outside of the power supply housing 10 and connects to the lamp housing. In one embodiment, the independent integrated antenna 30 includes an antenna connecting line 31, a guard coil 32, and an antenna housing 33 with the antenna body built in. One end of the antenna connecting line 31 is electrically connected to the control PCB circuit board 221, and the other end is electrically connected to the antenna body. The guard coil 32 is sleeved on the antenna connecting line 31. A first through hole 142 is opened on the housing end cover (i.e., housing end cover A14) that makes up the control housing 20. The guard coil 32 is installed in the first through hole 142 and is sealed to the first through hole 142. The antenna housing 33 is located outside the power supply housing 10 and is connected to the lamp housing. In some specific embodiments, the antenna connecting line 31 and the guard coil 32 are integrally injection molded. In some specific embodiments, the antenna housing 33 is provided with a slot 331 and / or double-sided adhesive 332, which are respectively connected to the lamp housing. In practical applications, the slot 331 and / or double-sided adhesive 332 can be located at opposite ends of the antenna housing 33 and connected to the lamp housing respectively. The specific location of the slot 331 and / or double-sided adhesive 332 is not unique.

[0055] The independent integrated antenna 30, as the core component for wireless signal transmission and reception, is responsible for data communication between the entire power supply device and external devices (such as intelligent control systems, mobile apps, etc.). It is key to realizing remote control, intelligent dimming, and color adjustment of light sources (such as LED lamps). Through precise signal reception and transmission, the independent integrated antenna 30 ensures accurate transmission of control commands, providing users with a convenient and intelligent lighting experience. The antenna body built into the antenna housing 33 can be an antenna circuit board, an EPC antenna, or an external rod antenna, etc. The antenna connecting cable 31 is sealed to the first through hole 142 of the housing end cover A14 via the protective coil 32. The antenna housing 33 is quickly connected to the lamp housing via the slot 331 and / or double-sided adhesive 332. Compared with the traditional SMA adapter and antenna requiring precise alignment and screw fixing, this simplifies the installation process, shortens product assembly time, and improves production efficiency. The design of the antenna connecting cable 31 and the protective coil 32 being integrally injection molded makes the overall structure of the independent integrated antenna 30 more compact, reducing instability caused by gaps and looseness between components.

[0056] This utility model also provides a power supply system, including a light source and a power supply device, wherein the light source and the power supply device are electrically connected. The power module 12 provides a stable power supply and converts the power supply into a specific voltage and current to drive the light source to emit light; the control module 22 receives control commands from the system cloud platform and transmits the commands to the system cloud platform to realize functions such as dimming, switching, and acquiring operational data of the lamp. The light source includes, but is not limited to, LED lights.

[0057] Installation of the power supply unit with end caps at both ends of the power supply housing 13: Slowly insert the power PCB circuit board 121 into the slot 133 on the inner side wall of the power supply housing 13, ensuring that the circuit board is fully embedded in the slot 133 and has a clearance fit with the slot 133, thus restricting the position of the power PCB circuit board 121 and preventing it from shaking significantly within the first hollow cavity 11. Before inserting the power PCB circuit board 121, ensure that the main heat-generating components 122 on the power PCB circuit board 121 are arranged in an area away from the installation position of the subsequent control module 22, leaving reasonable space for heat dissipation. Place the grounding wire 15, which is electrically connected to the power PCB circuit board 121, into the mounting groove 132 on the corresponding end face (which can be either the front end face or the rear end face of the power supply housing 13), ensuring that the grounding wire 15 fully abuts against the screw 16 to be installed later.

[0058] Electrically connect the power module 12 to the control module 22, and electrically connect the independent integrated antenna 30 to the control module 22. Place the control module 22 into the second hollow cavity 21 inside the control housing 20. Align the protective coil 32 of the independent integrated antenna 30 with the first through hole 142 on the housing end cover A14, and slowly press it in to seal the connection. Ensure that the slot 331 and / or double-sided adhesive 332 on the antenna housing 33 are correctly oriented to facilitate subsequent connection with the lamp housing. Install the control housing by connecting the housing wall 144 to the control wall 233.

[0059] The control housing 20, with the control module 22 and antenna installed, is placed into the first hollow cavity 11 of the power supply housing 13. Its position is adjusted to ensure it is logically aligned with the power module 12 and does not interfere with it. The housing end cap A14, which constitutes the control housing 20, is then placed on the rear end face of the power supply housing 13 and secured with screws 16. Potting compound is slowly injected from the front end of the power supply housing 13 until the area within the first hollow cavity 11 used to house the power module 12 is completely filled with potting compound. After the potting compound injection is complete, the housing end cap B19 is quickly aligned with the front end face of the power supply housing 13 and secured with screws 16.

[0060] It should be noted that one of the screws 16 abuts against the grounding wire 15 in the mounting groove 132 to achieve grounding.

[0061] It should be noted that the power supply device is not limited to a power supply device with end caps at both ends of the power supply housing body 13.

[0062] Advantages of this utility model:

[0063] Structural innovation: The power supply housing has two independent cavities designed to achieve efficient space utilization and space isolation, thus enabling product miniaturization; the design of the heating element location, combined with potting compound and air cavity design, optimizes heat dissipation performance.

[0064] Cost reduction: The innovative installation design of the grounding wire 15 reduces the number of parts and processes; the independent integrated antenna 30 replaces the traditional combination, simplifying the structure and reducing production, assembly and maintenance costs.
