Description

PCB board mounting lampshade, screwless mounting light panel plant light Technical Field

[0001] This utility model relates to the fields of PCB board mounting structure and plant light technology, and in particular to a lampshade for PCB board mounting and a screwless mounting lamp board type plant light. Background Technology

[0002] Currently, the PCB board in LED plant lights is typically fixed to the heat sink and lamp housing using bolts or screws to ensure a tight fit between the board and the heat sink, thus facilitating heat conduction and dissipation. For example, Chinese utility model patent CN211176487U discloses a plant lighting fixture in which the board is mounted on a mounting frame using screws. The board needs to be connected to the metal frame one by one with screws, requiring individual unscrewing during assembly and disassembly, which is inefficient.

[0003] In addition, Chinese utility model patent CN210630258U proposes a modular assembly plant growth light. Although its structure is relatively simple and the number of parts is relatively small, and only a few screws need to be tightened by hand to fix the light fixture during installation, the installation of the light panel still relies on screw tightening. This fails to eliminate the inherent cumbersome operation problem of screw connection. At the same time, there is a risk of local warping due to inconsistent screw tightening force, which affects the flatness of the light panel and the overall heat dissipation efficiency.

[0004] To avoid problems caused by screw installation, some technical solutions use adhesive or clips to fix components. For example, CN204300839U proposes using hot melt adhesive and clips to fix the driver power supply box, avoiding the use of screws. Although this structure can achieve screwless fixing, hot melt adhesive is prone to aging and falling off at high temperatures, resulting in insufficient reliability. Furthermore, this type of fixing method is mainly used for non-heat-dissipating, close-fitting components such as power supply boxes, and is difficult to apply directly to PCB lighting boards that require high adhesion.

[0005] For example, CN207006052U uses a PC transparent cover to enclose the light source. The cover and the main structure still rely on screws or clips for installation and removal, requiring tools and failing to achieve truly quick, screwless installation. Furthermore, this structure does not consider providing a clamping effect on the PCB board through the cover itself.

[0006] CN210950962U proposes a structure combining clips and screws for connecting light strips and crossbeams. Although this reduces the number of screws to some extent, it does not completely eliminate the reliance on screws.

[0007] Furthermore, the infrared supplementary light device disclosed in CN218782497U uses screws to lock the light plate with a T-shaped exhaust pipe, which continues the traditional screw fixing method. There is still room for improvement in terms of assembly efficiency, heat bonding performance, and ease of maintenance.

[0008] In summary, most existing PCB light board installation methods still rely on screws or hot melt adhesives, which generally suffer from problems such as complex assembly, uneven stress, low heat dissipation efficiency, and inconvenient maintenance. There is an urgent need for a new installation method that is simple in structure, has high assembly efficiency, and can ensure a reliable fit between the light board and the heat sink. Summary of the Invention

[0009] The purpose of this utility model is to provide a PCB board mounting lampshade and a screwless mounting lamp board type plant light to address the shortcomings of the existing technology. The aim is to design a PCB board mounting lampshade structure that allows the PCB lamp board to be quickly and firmly snapped onto the heat sink without any screws. This ensures a flat and close fit between the lamp board and the heat sink and efficient heat dissipation. It also integrates a lens in the cover to achieve light path refraction or focusing, while simplifying the structure, reducing costs, and facilitating later maintenance.

During maintenance, simply unlocking the clips is sufficient to replace the lamp board, greatly improving assembly and maintenance efficiency.

[0029] 2. Flat fit and optimized heat dissipation: The overall squeezing force applied by the pressure leg avoids the problem of uneven force in local screw fixing, ensuring that the PCB light board is always in close contact with the heat sink, ensuring efficient heat conduction and improving heat dissipation performance.

[0030] 3. Simplified structure and reduced cost: Eliminating multiple fasteners such as bolts and washers and their corresponding processes reduces the types of parts, making the production and assembly process simpler and reducing material and labor costs.

The terminology used in this specification is only for the purpose of describing specific embodiments and is not intended to limit the invention.

[0064] As shown in Figures 1-13, a retractable plant light 100 is provided in this embodiment of the utility model. Referring to Figures 2-6, the retractable plant light 100 includes: a support 1, a heat sink 2, a mounting base 3, a connecting rod, and a power supply 5. Wherein:

[0065] The bracket 1 consists of two brackets arranged side by side. Each bracket 1 includes two legs that are hinged to each other, and the two legs are foldable by means of hinge. The two brackets 1 are the first bracket 11 and the second bracket 12. The two legs of the first bracket 11 are the first leg 111 and the second leg 112, and the two legs of the second bracket 12 are the third leg 121 and the fourth leg 122. The third leg 121 and the first leg 111 are on the same side, and the fourth leg 122 and the second leg 112 are on the same side.

[0066] Heat sink 2 is arranged between the first bracket 11 and the second bracket 12. The heat sink 2 includes at least two heat sinks arranged side by side. Each heat sink 2 is provided with a PCB light board 23, and the PCB light board 23 is provided with a plurality of LED beads 231. The at least two heat sinks 2 are a first heat sink 21 and a second heat sink 22. One end of the first heat sink 21 is installed on the first support leg 111 and the other end is installed on the third support leg 121. One end of the second heat sink 22 is installed on the second support leg 112 and the other end is installed on the fourth support leg 122.

[0067] Mounting base 3 is arranged between the first heat sink 21 and the second heat sink 22;

[0068] The connecting rod includes a first connecting rod 41 and a second connecting rod 42; one end of the first connecting rod 41 is hinged to the first heat sink 21, and the other end of the first connecting rod 41 is hinged to one end of the mounting base 3; one end of the second connecting rod 42 is hinged to the second heat sink 22, and the other end of the second connecting rod 42 is hinged to the other end of the mounting base 3.

[0069] Power supply 5 is detachably mounted on mounting base 3.

[0070] Existing plant lights 100 typically consist of a heat sink 2 and a lamp plate arranged between two side-by-side supports 1, with the lamp plate fixed to the heat sink 2 and perpendicular to the lamp frame. For ease of transport and storage, the plant light 100 often needs to be designed as a foldable structure. Furthermore, for ease of wiring and design cost considerations, the power supply 5 is often placed precisely in the middle of the two supports 1 of the plant light 100. Currently, there are two main folding methods for achieving folding in these existing plant lights 100:

[0071] The first method (see Figure 1A) divides each of the two brackets 1 into three sections: a middle section and two side sections. The power supply 5 is placed in the middle section. Folding involves folding the side sections towards the middle section. The advantage of this method is that the power supply 5 can be folded and unfolded without removing it. The disadvantage is that folding the side sections will result in higher wiring and manufacturing costs.

[0072] The second type (see Figure 1B) divides each of the two supports 1 into two retractable sections, with the folding position at the middle of the support 1. The power supply 5 is located in the retractable position. The advantage of the second type is lower wiring and manufacturing costs. The disadvantage is that the power supply 5 needs to be disassembled and reassembled before retraction, otherwise retraction is not possible, resulting in low retraction efficiency for the plant light 100.

[0073] This solution overcomes the shortcomings of the two solutions mentioned above, achieving both the lower wiring and manufacturing costs of the second solution and the ability to fold the plant light 100 without disassembling the power supply 5, resulting in high folding efficiency. Furthermore, the power supply 5 can be removed from the mounting base 3, facilitating maintenance of the plant light 100 and allowing for easy replacement of the damaged power supply 5 without replacing the entire plant light 100, thus extending its lifespan and reducing costs. Specifically, it utilizes a double-bracket system 1 with parallel heat sinks 2. Two brackets 1 are arranged side-by-side, each consisting of two hinged legs. At least two heat sinks 2 are arranged side-by-side between the two brackets 1, fixing the power supply 5 between them. Synchronous folding is achieved through a connecting rod hinge, with two connecting rods respectively hinged to the two ends of the heat sink 2, forming a synchronous folding mechanism. This results in the following beneficial effects:

[0074] 1. The power supply 5 can be folded up without disassembling it. The power supply 5 and the heat sink 2 are hinged together by a connecting rod. When folding up, the entire structure folds up synchronously, eliminating the need to disassemble and assemble the power supply 5, and significantly improving folding up efficiency.

[0075] 2. Reduce wiring and manufacturing costs. The power supply 5 is centrally located between the two heat sinks 2, with short and concentrated wiring, eliminating the need for multiple wiring points on the bracket 1, simplifying the production process, reducing connection points, and lowering material and assembly costs.

[0076] 3. Easy maintenance and long service life. Although the power supply 5 is hinged to the heat sink 2, it can be completely removed from between the two heat sinks 2. When replacing or repairing, only the power supply 5 needs to be removed, without disassembling the bracket 1 or the heat sink 2, making maintenance more convenient and extending the life of the lamp.

[0077] In one embodiment, the heat sink 2 is perpendicular to the bracket 1, and the PCB lamp board 23 is arranged at the bottom of the heat sink 2.

[0078] Heat sink 2 is a heat-dissipating metal component, specifically a heat-dissipating aluminum component.

[0079] In another embodiment, the bottom of the heat sink 2 is provided with a lamp board mounting position 211 and a lamp board limiting part 212, with the lamp board limiting part 212 respectively disposed on both sides of the lamp board mounting position 211. The lamp board limiting part 212 is a lamp board limiting hook. The PCB lamp board 23 is placed in the lamp board mounting position 211.

[0080] In another embodiment, the bottom of the heat sink 2 is further provided with a lampshade mounting position 213, which is respectively provided on both sides of the lamp panel mounting position 211 and located on the side of the lamp panel limiting part 212 away from the lamp panel mounting position 211. A retaining part 214 is provided on the lampshade mounting position 213.

[0081] In another embodiment, a plant lampshade 6 is also provided at the bottom of the heat sink 2. Hook portions 61, which are hooked onto the holding portion 214, are provided on both sides of the plant lampshade 6. Pressure legs 62, which abut against the PCB lamp board 23, are also provided on both sides of the plant lampshade 6. Specifically, in a traditional plant lamp 100, the lamp board is fastened to the heat sink 2 using multiple screws. This not only makes lamp board installation difficult and reduces assembly efficiency, but also causes the lamp board to warp or arch in some areas, resulting in unevenness and preventing it from fully adhering to the surface of the heat sink 2, thus affecting the overall heat dissipation effect of the lamp board. In this solution, as shown in Figures 7-9, by providing a lamp board mounting position 211 at the bottom of the heat sink 2 to accommodate the PCB lamp board 23, and a plant lampshade 6 that can press the PCB lamp board 23 firmly, screwless installation of the PCB lamp board 23 is achieved. This facilitates easy assembly and disassembly, effectively improving the installation efficiency of the PCB lamp board 23, and also avoids the problem of unevenness caused by multiple screws affecting heat dissipation. In detail, the PCB lamp board 23 is installed in the lamp board mounting position 211, and the PCB lamp board 23 is first-level limited by the lamp board limiting parts 212 on both sides of the lamp board mounting position 211. Then, the plant lampshade 6 is installed on the bottom of the heat sink 2. Specifically, the hook part 61 of the plant lampshade 6 is snapped into the lampshade mounting position 213 and held in place by the holding part 214. At this time, the pressure leg 62 of the plant lampshade 6 will press against the PCB lamp board 23, forming a certain compressive force on the PCB lamp board 23, thereby making the PCB lamp board 23 fully fit against the surface of the heat sink 2, effectively improving the heat dissipation effect. The installation of the plant lampshade 6 and the full fixation of the PCB lamp board 23 are effectively combined synchronously, improving assembly efficiency. This effectively avoids the problem of the lamp board partially lifting due to different screw tightness, which would affect the heat dissipation effect.

[0082] In another embodiment, as shown in Figures 2, 6 and 13, each bracket 1 is provided with 6 lamp mounting positions, and the end of the heat sink 2 is matched and installed on the lamp mounting position. That is, each bracket 1 is connected to 6 heat sinks 2, and each heat sink 2 is matched and installed with a PCB lamp board 23. Each plant lamp 100 is equipped with 6 PCB lamp boards 23.

[0083] The plant lampshade 6 is also equipped with a convex lens 63 for refracting the light path. Specifically, as shown in Figures 10-13, since the planting area 200 and the plant lamp 100 are of the same length, the light emitted by the LED beads 231 on the plant lamp 100 easily overflows into the planting area 200, resulting in wasted light energy. The convex lens 63 on the plant lampshade 6 is used to refract the 120-degree light angle emitted by the LED beads 231 on the PCB lamp board 23 into a 90-degree light angle (see Figures 11 and 13), thereby preventing the light paths emitted by the middle four of the six PCB lamp boards 23 from overflowing into the planting area 200, maximizing the utilization of light energy and avoiding light source waste. The two outermost of the six PCB lamp boards 23 are polarized to one side by a convex lens 63 (see Figures 12 and 13). This is also to avoid the light source overflowing out of the planting area 200 and causing light source waste. Specifically, one side of the light angle is perpendicular to the planting area 200, and the other side is at a certain angle to the planting area 200.

[0084] A screwless mounting structure for a PCB board, as shown in Figures 7-9, includes: a heat sink 2 and a plant lampshade 6. Wherein:

[0085] The heat sink 2 has a lamp board mounting position 211 placed on the PCB board at the bottom, and lamp cover mounting positions 213 respectively arranged on both sides of the lamp board mounting position 211.

[0086] The plant lampshade 6 has hooks 61 on both sides that are fastened to the lampshade mounting position 213, and pressure legs 62 on both sides for abutting against the PCB board. The bottom of the heat sink 2 also has lamp board limiting parts 212 arranged on both sides of the lamp board mounting position 211, with the lampshade mounting position 213 located on the side of the lamp board limiting parts 212 away from the lamp board mounting position 211. The lampshade mounting position 213 has a locking part 214 hooked by the hooks 61. This screwless PCB board mounting structure also includes a PCB board placed in the lamp board mounting position 211. The PCB board is a PCB lamp board 23 with a plurality of LED beads 231. This screwless PCB board mounting structure can achieve the following beneficial effects:

[0087] 1. Screwless quick-release snap-fit ​​fixing. By setting a lamp board mounting position 211 and a lampshade mounting position 213 at the bottom of the heat sink 2, the hook part 61 of the plant lampshade 6 snaps into the lampshade mounting position 213, and the pressure leg 62 forms a uniform pressing force on the PCB board, which can realize screwless quick assembly and disassembly, greatly improving assembly efficiency. During maintenance, the PCB board can be removed simply by loosening the snap, making replacement convenient.

[0088] 2. Smooth fit and optimized heat dissipation. The overall compressive force generated by the pressure leg 62 avoids the problem of lamp board warping caused by uneven local force in traditional bolt-type systems, ensuring that the PCB board is always in close contact with the heat sink 2, ensuring efficient heat conduction and improving heat dissipation.

[0089] 3. Simple structure and reduced cost. Eliminating parts such as bolts, nuts, and washers reduces the types of components and inventory, simplifies production and assembly processes, and lowers material and labor costs.

[0090] 4. High reliability and compatibility. The snap-fit ​​+ pressure leg 62 structure requires no additional bonding materials, has excellent high temperature resistance and vibration resistance, and is compatible with common PCB light board 23 size, giving it strong versatility and mass production advantages.

[0091] A plant light 100 includes the aforementioned PCB board screwless mounting structure.

[0092] A lampshade for mounting a PCB board includes: a main body, with hook portions 61 on both sides and pressure legs 62 on both sides for abutting against the PCB board. The main body also has a lens 63 for refracting light. The lens 63 is a convex lens. The main body is a plant lampshade 6. The PCB board is a PCB board 23 for a plant lamp 100, which is equipped with a plurality of LED beads 231. This lampshade for mounting a PCB board can achieve the following beneficial effects:

[0093] 1. Screwless quick assembly and disassembly: By pre-setting lamp board mounting position 211 and lamp cover mounting position 213 at the bottom of the heat sink 2, and with the hooks 61 on both sides of the lamp cover snapping into the mounting position, and the pressure leg 62 generating uniform extrusion force on the PCB board, screwless quick fixing and disassembly can be achieved. During maintenance, the lamp board can be replaced simply by unlocking the clips, which greatly improves assembly and maintenance efficiency.

[0094] 2. Flat fit and optimized heat dissipation: The overall squeezing force applied by the pressure leg 62 avoids the problem of uneven force in local screw fixing, so that the PCB lamp board 23 is always in close contact with the heat sink 2, ensuring efficient heat conduction and improving heat dissipation performance.

[0095] 3. Simplified structure and reduced cost: Eliminating multiple fasteners such as bolts and washers and their corresponding processes reduces the types of parts, making the production and assembly process simpler and reducing material and labor costs.

[0096] 4. High-temperature reliability: No hot melt adhesive, does not rely on adhesives or screws, the buckle + 62-leg structure remains firm and reliable in high-temperature and vibration environments, with strong applicability and long maintenance cycle.

[0097] 5. Integrated lens 63 to improve light efficiency: A convex lens 63 is set in the lampshade body to refract or focus the diffused light of the LED to the planting area, as shown in the application of lens 63 in the modular intelligent plant light 100, which effectively reduces light energy waste and improves lighting utilization.

[0098] A screwless mounting light panel type plant light includes: a plant lampshade 6, a PCB light board 23, and a heat sink 2, wherein:

Wherein:

[0105] The bracket 1 consists of two units arranged side by side, each bracket 1 including two legs that are hinged to each other;

It can be folded as a whole without disassembling any parts, making transportation and installation more convenient.

[0113] 2. Precise light source coverage. Continuous lamp board mounting positions 211 are set at the bottom of the side-by-side heat sink 2, and the maximum distance between any two PCB lamp boards 23 is limited to no more than the length of the planting area 200, ensuring that the output beam of each lamp board uniformly covers the entire planting area without any waste of light energy.

[0114] 3. Tool-free and screw-free quick maintenance. The PCB lamp board 23 and power supply 5 are fixed to the mounting base 3 by the snap-on lampshade mounting position 213. The hook part 61 and the pressure leg 62 generate uniform pressure, which can be disassembled and assembled without screws or tools, making maintenance and replacement more efficient.

[0115] 4. Optimize thermal management and reliability. The bottom of the heat sink 2 is also provided with a lamp board limiting part 212 and a lamp cover mounting position 213. The PCB lamp board 23 is further limited and squeezed by the pressure leg 62 to avoid local warping, enhance heat dissipation efficiency, and maintain structural reliability under long-term high temperature environment.

[0116] 5. Adjustable illumination height. The optimal distance between the support 1 and the planting area 200 is preset to 30 cm-50 cm. With the help of LED beads 231 and lens 63 (optional), the light path can be refracted or focused, which can meet the needs of plant photosynthesis while taking into account energy consumption and light uniformity.
