Description

Technical Field

[0001] This utility model relates to the field of plant lamp technology, specifically to a high-efficiency heat dissipation nine-hole COB integrated plant lamp housing. Background Technology

[0002] In the field of plant cultivation, especially in indoor cultivation, greenhouse cultivation, and plant research, plant lights play a crucial role. Nine-hole COB integrated plant lights, with their advantages such as customized spectral output and a rich variety of wavelengths, can meet the needs of specific plant propagation and growth, accelerate crop breeding, and alter crop growth cycles, thus gaining widespread application. However, in practical use, nine-hole COB integrated plant lights also face some problems that urgently need to be addressed.

[0003] COB light sources generate a significant amount of heat during operation. If this heat cannot be dissipated promptly, it will cause the LED chips to overheat, affecting luminous efficacy and lifespan. For plant lights, reduced luminous efficacy impacts photosynthesis and growth, while frequent replacements increase operating costs and maintenance workload. Existing plant light housings have limitations in heat dissipation. Some housings have simple heat dissipation designs, relying solely on natural convection, resulting in low efficiency and failing to meet the heat dissipation requirements of high-power nine-hole COB integrated plant lights. While some heat dissipation structures employ fins, insufficient optimization in heat conduction and airflow leads to heat accumulation inside the light fixture, preventing rapid and effective dissipation to the surrounding environment. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency heat dissipation nine-hole COB integrated plant lamp housing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat dissipation nine-hole COB integrated plant lamp housing, comprising a protective base plate, a fixed frame, and a top cover. The top cover and the protective base plate are respectively disposed at the upper and lower ends of the fixed frame. A PCB board is installed inside the protective base plate through an inner plate. LED beads are evenly disposed on the top of the PCB board. Encapsulation slots are provided on the outer sides of the LED beads in the same row. Each encapsulation slot has an airflow port one, an airflow port two, and an airflow port three at both ends.

[0006] The inner cover is provided at the position of the LED lamp bead on the inner side of the top cover, and the outer cover is provided on the outer side of the inner cover. An airflow channel is formed between the outer cover and the inner cover, and air vents are provided at both ends of the airflow channel.

[0007] Both ends of the fixed frame are provided with ventilation openings, and an exhaust fan and an intake fan are respectively installed on the inner side of the two ventilation openings at the positions corresponding to the air vents.

[0008] Furthermore, a heat-conducting base plate is also provided on the top of the protective base plate below the inner plate. The two ends of the heat-conducting base plate extend to the outside of the fixed frame and are evenly provided with heat dissipation fins. The two sides of the fixed frame are also evenly provided with slots that match each heat dissipation fin.

[0009] Furthermore, each of the two ventilation openings has a slot, and a protective net is installed inside each slot.

[0010] Furthermore, the opening of the inner cover is provided with a transparent panel for the light from the LED beads to be exposed.

[0011] Furthermore, the opening of the fixed frame is provided with an installation groove for fixing the top cover, and both the upper and lower ends of the side wall of the fixed frame are evenly provided with locking screws that connect to the top cover and the protective base plate.

[0012] Furthermore, sealing gaskets are provided at the connection between the fixed frame and the top cover, as well as at the connection between the fixed frame and the protective base plate.

[0013] Furthermore, a microcontroller and a temperature sensor are also mounted on the PCB board.

[0014] This invention provides a highly efficient heat dissipation nine-hole COB integrated plant lamp housing, which has the following significant advantages compared to existing technologies:

[0015] 1. The airflow channel formed between the inner and outer covers on the inside of the top cover, along with the vents at both ends of the airflow channel, ensures smooth airflow and further improves heat dissipation. The vents at both ends of the fixed frame, in conjunction with the exhaust and intake fans, form an effective forced convection cooling system, allowing internal heat to be quickly dissipated and maintaining the LED beads at a suitable operating temperature. The slots at the vent openings and the internal protective mesh ensure airflow while effectively preventing foreign objects from entering, enhancing safety during use.

[0016] 2. By installing a heat-conducting base plate on top of the protective base plate, and evenly distributing heat dissipation fins extending to both ends of the base plate to the outside of the fixing frame, the heat dissipation area is effectively increased, greatly improving heat dissipation efficiency. The heat-conducting base plate is in close contact with the PCB board, enabling rapid conduction of heat generated by the LED beads to the heat dissipation fins, which are then quickly dissipated through air convection, preventing heat accumulation. The matching slots on both sides of the fixing frame further optimize the heat dissipation structure, ensuring the heat dissipation fins function stably and efficiently.

[0017] 3. The transparent panel at the opening of the inner cover ensures uniform light transmission from the LED beads, avoids light scattering, and improves the lighting effect. The nine-hole COB integrated design makes the LED beads more evenly distributed, the light coverage area larger, and the light efficiency higher, making it particularly suitable for the uniform light required for plant growth.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-5 The present invention provides an embodiment of a high-efficiency heat dissipation nine-hole COB integrated plant lamp housing, comprising a protective base plate 9, a fixed frame 1 and a top cover 7. The top cover 7 and the protective base plate 9 are respectively disposed at the upper and lower ends of the fixed frame 1, and a PCB board 11 is installed inside the protective base plate 9 through an inner plate 10. A microcontroller controller and a temperature sensor are also installed on the PCB board 11.

[0026] The top of the protective base plate 9 below the inner plate 10 is also provided with a heat-conducting base plate 3. The two ends of the heat-conducting base plate 3 extend to the outside of the fixed frame 1 and are evenly provided with heat dissipation fins 301. The two sides of the fixed frame 1 are also evenly provided with slots 103 that match each heat dissipation fin 301.

[0027] The top cover 7 and the protective base plate 9 are respectively set at the upper and lower ends of the fixed frame 1, forming a closed space for installing and protecting the internal electronic components.

[0028] The protective base plate 9 is located at the bottom of the entire outer shell, serving a supporting and protective function. A PCB board 11 is mounted inside the protective base plate 9 via an inner plate 10. A microcontroller and a temperature sensor are mounted on the PCB board 11 to control the operating status of the plant light and monitor its internal temperature.

[0029] The inner plate 10 is fixed above the protective base plate 9 to support the PCB board 11. The inner plate 10 is made of a board material with good insulation and thermal conductivity to ensure the safe and stable operation of the PCB board 11.

[0030] A heat-conducting base plate 3 is also provided on the top of the protective base plate 9 below the board 10. The main function of the heat-conducting base plate 3 is to quickly conduct the heat generated by the PCB board 11 to the outside, thereby achieving efficient heat dissipation. The two ends of the heat-conducting base plate 3 extend to the outside of the fixing frame 1, and heat dissipation fins 301 are evenly arranged on its surface.

[0031] The heat dissipation fins 301 are evenly distributed on both sides of the heat-conducting base plate 3, increasing the heat dissipation area and improving heat dissipation efficiency. The shape and size of each heat dissipation fin 301 are optimized to ensure the best heat dissipation effect.

[0032] The fixed frame 1 is the main structure of the entire shell, and its two sides are evenly provided with slots 103 that match each heat dissipation fin 301. The design of the slots 103 allows the heat dissipation fin 301 to be firmly embedded in them, ensuring the safety of the heat dissipation fin 301 during transportation and use.

[0033] The top cover 7 is located above the fixed frame 1, forming a closed space together with the protective base plate 9.

[0034] LED beads 6 are evenly arranged on the top of the PCB board 11. Each row of LED beads 6 has a packaging slot 2 on its outer side. Each packaging slot 2 has an airflow port 1 201, an airflow port 202 and an airflow port 3 203 at both ends.

[0035] An inner cover 704 is provided on the inside of the top cover 7 at the position corresponding to the LED light bead 6. A transparent panel 702 is provided at the opening of the inner cover 704 for the light of the LED light bead 6 to be exposed.

[0036] An outer cover 703 is provided on the outside of the inner cover 704. An airflow channel 705 is formed between the outer cover 703 and the inner cover 704. An air outlet 701 is provided at both ends of the airflow channel 705.

[0037] Multiple LED beads 6 are evenly arranged on the top of the PCB board 11. The LED beads 6 are arranged in a certain row and column to form a matrix structure. Each column of LED beads 6 has a packaging slot 2 on its outer side for cooperating with the inner cover 704 and the outer cover 703.

[0038] Each packaging tray 2 has three airflow ports at both ends: airflow port one 201, airflow port two 202, and airflow port three 203. This optimizes heat dissipation and ensures that the temperature of the LED beads 6 is effectively controlled during long-term operation.

[0039] An inner cover 704 is provided on the inner side of the top cover 7 at the position corresponding to each LED bead 6. A transparent panel 702 is provided at the opening of the inner cover 704 to allow light from the LED bead 6 to pass through, while preventing dust and impurities from entering the interior of the inner cover.

[0040] An outer cover 703 is provided on the outer side of the inner cover 704. An airflow channel 705 is formed between the outer cover 703 and the inner cover 704, and an air vent 701 is provided at both ends of the airflow channel 705. The design of the air vent 701 ensures air circulation within the airflow channel 705, further improving the heat dissipation effect.

[0041] Ventilation openings 102 are provided at both ends of the fixed frame 1. An exhaust fan 5 and an intake fan 8 are respectively installed on the inner side of the two ventilation openings 102 at the positions corresponding to the air inlet 701.

[0042] Both ventilation openings 102 have slots 104 at their openings, and each slot 104 has a protective net 4 installed inside.

[0043] The fixing frame 1 of this utility model has an overall rectangular parallelepiped structure, with ventilation openings 102 at both ends. The design of the ventilation openings 102 is intended to ensure air circulation and improve the ventilation efficiency of the device.

[0044] Inside the ventilation openings 102 at both ends of the fixed frame 1, corresponding to the positions of the air inlets 701, an exhaust fan 5 and an intake fan 8 are respectively installed. The installation positions of the exhaust fan 5 and the intake fan 8 are carefully designed to ensure smooth and efficient airflow. Specifically, the exhaust fan 5 is installed inside the ventilation opening 102 at one end of the fixed frame 1, and its function is to exhaust hot or stale air from inside; the intake fan 8 is installed inside the ventilation opening 102 at the other end of the fixed frame 1, and its function is to introduce fresh air from outside.

[0045] Furthermore, each of the two vents 102 has a slot 104 at its opening. The slot 104 not only increases the structural stability of the vent 102, but also facilitates the subsequent installation of the protective net 4. A protective net 4 is installed inside each slot 104. The function of the protective net 4 is to prevent external debris from entering the vent 102, thereby protecting the normal operation of the exhaust fan 5 and the intake fan 8.

[0046] The protective net 4 can effectively block debris without significantly obstructing airflow.

[0047] During use, the intake fan 8 starts first, introducing fresh outside air into the fixed frame 1 through the vent 102. As the air passes through the protective net 4, external debris is effectively intercepted, ensuring that the air entering the interior is clean. Subsequently, the exhaust fan 5 starts, expelling hot or stale air from inside the fixed frame 1 through the vent 102 at the other end.

[0048] Through the coordinated operation of the exhaust fan 5 and the intake fan 8, continuous and efficient air circulation can be achieved inside the fixed frame 1, thereby maintaining a fresh and comfortable internal environment.

[0049] The fixed frame 1 has an installation groove 101 for fixing the top cover 7 at the opening, and the upper and lower ends of the side wall of the fixed frame 1 are evenly provided with locking screws that connect to the top cover 7 and the protective base plate 9.

[0050] Sealing gaskets are provided at the connection between the fixed frame 1 and the top cover 7, as well as at the connection between the fixed frame 1 and the protective base plate 9.

[0051] The mounting slot 101 is rectangular in shape to ensure that the top cover 7 can be securely embedded therein.

[0052] The fixed frame 1 has locking screw holes evenly distributed at both the upper and lower ends of its side wall for connecting to the top cover 7 and the protective base plate 9. Specifically, the upper locking screw hole is located near the edge of the opening, and the lower locking screw hole is located near the bottom edge.

[0053] Sealing gaskets are provided at the connection between the top cover 7 and the fixed frame 1, and at the connection between the protective base plate 9 and the fixed frame 1. The sealing gaskets are preferably made of high-temperature resistant and corrosion-resistant rubber. The function of the sealing gaskets is to improve the sealing performance of the connections and prevent external moisture, dust, and other contaminants from entering the internal structure.

[0054] In this embodiment, when the plant light is turned on, the microcontroller controller controls the working state of the LED beads 6 based on the internal temperature information monitored by the temperature sensor. The intake fan 8 starts, introducing fresh external air into the fixed frame 1 through the vent 102. As the air passes through the protective mesh 4, debris is intercepted. After entering the fixed frame 1, the air circulates through the airflow ports at both ends of the encapsulation tray 2 and the airflow channel 705 between the inner cover 704 and the outer cover 703. The heat generated by the LED beads 6 is conducted through the PCB board 11 to the heat-conducting base plate 3, and then from the heat-conducting base plate 3 to the heat dissipation fins 301, dissipating the heat through air convection. The exhaust fan 5 starts, expelling hot or polluted air from inside the fixed frame 1 through the vent 102 at the other end, forming a forced convection cooling system to maintain a suitable internal temperature and ensure that the LED beads 6 operate at a suitable working temperature.
