Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically a high-power LED lighting fixture that dissipates heat through conduction and convection. Background Technology

[0002] As an emerging green light source, LEDs offer numerous advantages such as energy saving and environmental friendliness, leading to their increasing application in various lighting fields. LEDs are solid-state light sources that directly convert electrical energy into visible light output. With the continuous development of LED technology, current LED light sources boast high power, emitting high-brightness light. These high-power LEDs are now used in lighting equipment for various large venues. High-power LED lamps are primarily used for lighting plants no taller than 1 meter, as well as for assisting the growth of plants taller than 1 meter during their growth stage, and for floor-standing lighting. One of the key factors affecting the lifespan of LED lamps is heat dissipation; effective heat dissipation methods are crucial for extending the lifespan of LED lamps.

[0003] In existing technologies, high-power LED lamps mostly use conduction, convection, and forced cooling by fans for heat conduction and dissipation. Convection often uses heat pipes and coolant to dissipate heat from the lamp, while forced cooling by fans uses fan suction and blowing to dissipate heat from the LED light source. Both of these methods require heat dissipation devices and the space and location needed to install them, which increases the cost and size of the lamps. Furthermore, traditional lamp assembly usually involves using several screws, which results in relatively low assembly efficiency and poor practicality. Utility Model Content

[0004] The purpose of this invention is to provide a high-power LED lamp that conducts heat through convection to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-power LED lamp with self-convection heat dissipation, comprising a transparent lampshade, a lamp body disposed on the inner side of the transparent lampshade, a plurality of slots symmetrically opened on the outer wall of the lamp body, a light source plate disposed in the slots, a plurality of heat sinks symmetrically arranged on the inner wall of the light source plate, an upper cover and a lower cover disposed at the upper and lower ends of the transparent lampshade respectively, a silicone sealing gasket disposed on the inner side of the upper cover and the lower cover respectively, a fixing post disposed below the lower cover, a base disposed at the lower end of the fixing post, brackets symmetrically disposed on the outer side of the base, the two ends of the lamp body being connected to the upper cover and the lower cover respectively through connecting mechanisms, the two ends of the fixing post being connected to the base and the upper cover respectively through connecting mechanisms, and a power supply control component disposed inside the fixing post.

[0006] Furthermore, the connecting mechanism includes a fixed base, a connecting column movably mounted on the inner side of the fixed base, and a handle connected to the upper end of the connecting column. The top surface of the handle has a hexagonal groove. The inner wall of the fixed base has symmetrically formed storage grooves. A locking rod is rotatably mounted in the upper part of the storage groove. The side of the locking rod away from the locking groove is fixedly connected to the inner wall of the storage groove by a spring. The outer wall of the connecting column has symmetrically formed limiting grooves that match the locking rod. The design of the connecting mechanism allows the upper and lower covers to be quickly connected to the lamp body, and facilitates quick assembly and connection between the fixed column, the base, and the upper cover, improving the assembly efficiency of the lamp and enhancing its practicality.

[0007] Furthermore, a limiting strip is fixedly installed in the upper part of the storage groove, and the limiting strip is located on the side of the clamp rod away from the connecting column. A limiting block adapted to the limiting strip is connected to the upper end of the clamp rod near the limiting strip, and the limiting block is located above the limiting strip, so as to limit the clamp rod and improve the limiting and fixing effect of the clamp rod on the connecting column.

[0008] Furthermore, the inner wall of the fixed base is symmetrically provided with guide bars, and the outer wall of the connecting column is symmetrically provided with rail grooves adapted to the guide bars. The two rail grooves are arranged perpendicularly to the two storage grooves to guide and limit the connecting column, and facilitate the transmission of power to the fixed base when the connecting column is twisted.

[0009] Furthermore, the inner wall of the lamp body and one end of the fixing column are each provided with several mounting slots, and the mounting slots penetrate the lamp body and the fixing column respectively. The mounting slots are adapted to the fixing seat. The inner walls at both ends of the lamp body are provided with several internal threads, and the outer wall of the fixing seat is provided with several external threads, so as to install the fixing seat and make it detachable.

[0010] Furthermore, the lamp body is a hexagonal structure made of aluminum. Both the upper and lower covers have through holes, and one end of each of the upper and lower covers has a mounting hole corresponding to the mounting groove. The bottom surface of the base has an opening. The upper end of the bracket is inserted into a slot in the side wall of the fixing column, and the lower end of the bracket is fixedly connected to the base by screws, so as to make the connection between the bracket and the fixing column firm and improve the stability of the lamp.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When the lamp of this utility model is powered on and emits light, the LED beads on the light source board generate a large amount of heat. The heat is conducted through the lamp body to multiple heat sinks on the corresponding six sides inside, thereby heating the surrounding air. The hot air rises and flows into the outside air through the through hole in the middle of the upper cover. At the same time, the outside cold air flows into the lamp body through the base, the mounting groove and the through hole in the middle of the lower cover, forming air convection. This carries away the large amount of heat generated by the LED beads, making its heat conduction and heat dissipation functions simple and effective, saving costs and reducing the materials required for heat dissipation and the overall volume of the lamp.

[0023] 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.

[0024] Example: Figure 1 - Figure 7As shown, this utility model provides a technical solution: a high-power LED lamp with heat dissipation through conduction and convection, including a transparent lampshade 1, a lamp body 2 inside the transparent lampshade 1, a plurality of slots 11 symmetrically opened on the outer wall of the lamp body 2, a light source plate 3 inside the slots 11, a plurality of heat sinks 4 symmetrically arranged on the inner wall of the light source plate 3, an upper cover 5 and a lower cover 6 at the upper and lower ends of the transparent lampshade 1 respectively, silicone sealing gaskets 7 on the inner side of both the upper cover 5 and the lower cover 6, a fixing post 8 below the lower cover 6, a base 9 fitted at the lower end of the fixing post 8, and brackets 10 symmetrically arranged on the outer side of the base 9, the two ends of the lamp body 2 being connected to the upper cover 5 and the lower cover 6 respectively through connecting mechanisms, and the two ends of the fixing post 8 respectively The fixed column 8 is connected to the base 9 and the top cover 5 via a connecting mechanism. The fixed column 8 is equipped with a power supply control component. In this example, the power supply control component includes a drive power supply, a control board, thermally conductive potting compound, a power input line, a power output line, a signal input line, a signal output line, and connecting wires. The drive power supply and the control board are installed inside the aluminum fixed column 8 and sealed with thermally conductive potting compound. The power input line, the signal input line, and the signal output line are fixed on the fixed column 8. The power input line is connected to the drive power supply, the power output line is connected to the control board, and the signal input line and the signal output line are connected to the control board. The six light source boards 3 are connected to the control board respectively via connecting wires. In this example, the connecting mechanism includes a fixed base 13, a connecting column 14 is movably installed inside the fixed base 13, and a handle is connected to the upper end of the connecting column 14. A hexagonal groove is opened on the top surface of the handle. A storage groove 19 is symmetrically opened on the inner wall of the fixed base 13. A locking rod 15 is rotatably installed in the upper part of the storage groove 19. The side wall of the locking rod 15 away from the locking groove 11 is fixedly connected to the inner wall of the storage groove 19 by a spring 16. A limiting groove 20 adapted to the locking rod 15 is symmetrically opened on the outer wall of the connecting column 14. The setting of the connecting mechanism allows the upper cover 5 and the lower cover 6 to be quickly connected to the lamp body 2, and facilitates the quick assembly connection between the fixed column 8, the base 9 and the upper cover 5, improving the assembly efficiency of the lamp and making it more practical. In this example, a limiting strip 17 is fixedly installed in the upper part of the storage slot 19, and the limiting strip 17 is located on the side of the clamping rod 15 away from the connecting column 14. A limiting block 18 adapted to the limiting strip 17 is connected to the upper end of the clamping rod 15 near the limiting strip 17, and the limiting block 18 is located above the limiting strip 17, so as to limit the clamping rod 15 and improve the limiting and fixing effect of the clamping rod 15 on the connecting column 14. In this example, guide strips 21 are symmetrically provided on the inner wall of the fixing base 13, and rail grooves 22 adapted to the guide strips 21 are symmetrically opened on the outer wall of the connecting column 14. The positions of the two rail grooves 22 are perpendicular to the positions of the two storage slots 19, so as to guide and limit the connecting column 14 and facilitate the transmission of power to the fixing base 13 when the connecting column 14 is twisted.

[0025] In this example, several mounting slots 12 are respectively provided on the inner wall of the lamp body 2 and one end of the fixing post 8, and the mounting slots 12 penetrate the lamp body 2 and the fixing post 8 respectively. The mounting slots 12 are adapted to the fixing seat 13. Several internal threads are provided on the inner walls of both ends of the lamp body 2, and several external threads are provided on the outer wall of the fixing seat 13. In this example, the height position of the fixing seat 13 installed in the mounting slot 12 can be selected and set according to the actual situation without affecting the later disassembly, so as to install the fixing seat 13 and make it removable. In this example, the lamp body 2 is an aluminum hexagonal structure. The upper cover 5 and the lower cover 6 are both provided with through holes. One end of the upper cover 5 and the lower cover 6 is provided with mounting holes corresponding to the mounting slots 12. The bottom surface of the base 9 is provided with an opening. The upper end of the bracket 10 is inserted into the slot opened in the side wall of the fixing post 8. The lower end of the bracket 10 is fixedly connected to the base 9 by screws, so as to make the connection between the bracket 10 and the fixing post 8 firm and improve the stability of the lamp.

[0026] The working principle of this utility model is as follows: When the lamp is powered on and illuminates, the LED beads on the lamp body 2 generate a large amount of heat. This heat is conducted through the lamp body 2 to multiple heat sinks 4 on its six corresponding sides. The heat sinks 4 heat the surrounding air, causing the generated hot air to rise and flow into the outside air through the through hole in the middle of the upper cover 5. At the same time, the cold air at the bottom of the outside flows in through the through hole in the middle of the base 9, the aluminum fixing post 8, and the lower cover 6, forming air convection, which carries away the large amount of heat generated by the LED beads. In addition, the heat generated by the driver power supply and control board is conducted to the aluminum fixing post 8 through the thermally conductive potting compound. The generated heat is also carried away by the self-convection of the lamp, thus achieving heat dissipation. This makes the heat conduction and heat dissipation functions of the device not only simple and effective, but also greatly saves costs, optimizes the structure of the lamp, and reduces the materials required for heat dissipation and the overall volume of the lamp.

[0027] When assembling the lamp, taking the connection between the upper cover 5 and the lamp body 2 as an example, the fixing seat 13 is first installed into the mounting groove 12 opened in the lamp body 2. Then, after placing the silicone sealing gasket 7 inside the upper cover 5, one end of the upper cover 5 is placed on the outside of the lamp body 2 and the transparent lampshade 1. Then, the lower end of the connecting post 14 is passed through the mounting hole on the upper cover 5 and inserted into the inner side of the fixing seat 13. The lower end of the fixing seat 13 will squeeze and push the locking rod 15 to rotate around its rotating connection with the inner wall of the storage groove 19, so that the locking rod 15 gradually moves into the storage groove 19. At the same time, the locking rod 15 will squeeze the spring 16 until the locking rod 15 is completely moved into the storage groove 19. Then, the connecting post 14 continues to move down. When the limiting groove 20 opened on the side wall of the connecting post 14 and the limiting groove 20 are connected to the lamp body 2, the connecting post 14 continues to move down. When the locking rod 15 is aligned, the lower end of the locking rod 15 will be reset and rotated under the elastic force of the spring 16, so that the lower end of the locking rod 15 moves into the limiting groove 20 until the lower end of the locking rod 15 abuts against the inner wall of the limiting groove 20. At this time, the limiting block 18 connected to the upper end of the locking rod 15 will also fit against the top surface of the limiting strip 17, thereby limiting the limiting strip 17. This allows the locking rod 15 to limit and fix the connecting post 14, and then the connecting post 14 can connect and fix the upper cover 5 and the lamp body 2, thereby completing the assembly connection between the lamp body 2 and the upper cover 5. After that, the above steps can be repeated to connect the lamp body 2 and the upper cover 5, the upper cover 5 and the fixing post 8, and the base 9 and the fixing post 8, making the lamp assembly quick, improving assembly efficiency, and enhancing practicality.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
