Description

Technical Field

[0001] This utility model belongs to the technical field of double-sided LED lights, and in particular relates to a double-sided LED light with heat dissipation fins on the top. Background Technology

[0002] In large-space lighting scenarios such as industrial lighting, warehouses, supermarkets, and outdoor venues, traditional single-sided LED lights suffer from uneven illumination and numerous shadow areas. Furthermore, under high-power conditions, the core components of the lamp body are prone to heat accumulation, which not only leads to accelerated light decay and color temperature shift but also shortens the lifespan of LED chips and driver power supplies, increasing maintenance costs. At the same time, conventional heat dissipation structures are mostly side-mounted, with limited heat dissipation area and low heat conduction efficiency, making it difficult to meet the heat dissipation requirements of high-power double-sided lighting.

[0003] According to a public announcement (publication number: CN218154118U), an LED lamp with good heat dissipation effect includes an LED lamp body and a mounting base. The LED lamp body is provided on the top of the mounting base, and a heat sink is provided on the top of the mounting base. The heat sink is annular and fits around the LED lamp body. An inner cavity is provided inside the mounting base, and a cooling fan is provided inside the inner cavity. Multiple air slots are provided on the heat sink around the LED lamp body.

[0004] In the aforementioned application, the interaction between components such as the mounting base and cooling fan makes it difficult to solve the problem of increasing the air contact area through serrated grooves, extending the airflow contact time through wave grooves and forming turbulence, which can quickly remove the heat generated by the LED core board, and guiding the hot airflow smoothly out through the inclined block. This results in a reduction of the air contact area, a shortening of the airflow contact time, and the formation of turbulence, making it difficult to quickly remove the heat generated by the LED core board. The hot air is difficult to expel smoothly, causing heat accumulation at the top of the lamp body, accelerating component aging, making it difficult to maintain operation at a suitable temperature, increasing the light decay problem caused by high temperature, and making it difficult to ensure the stability of the luminous brightness and color temperature of the lamp. This needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a double-sided LED light with heat dissipation fins on the top. By enhancing the heat dissipation effect through the cooperation between components such as serrated grooves and inclined blocks inside the component, the existing problem of not being able to solve the problem of increasing the air contact area through serrated grooves, extending the airflow contact time and forming turbulence through wave grooves, which can quickly remove the heat generated by the LED core board, and guiding the hot airflow to be discharged smoothly through inclined blocks.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a double-sided LED light with heat dissipation fins on the top, including a double-sided shell, an LED lamp core board on the inner wall of the double-sided shell, and a heat dissipation enhancement component on the side of the double-sided shell. The heat dissipation enhancement component includes heat dissipation fins, the side of the heat dissipation fins is disposed on the double-sided shell, the surface of the heat dissipation fins has serrated grooves, the surface of the heat dissipation fins has wavy grooves, and an inclined block is fixedly connected to the side of the heat dissipation fins.

[0007] Furthermore, several serrated grooves are provided and are arranged in a linear array on the surface of the heat dissipation fins. Two LED core boards are provided. Serrated grooves and wave grooves are provided on the surface of several heat dissipation fins that were originally flat. They are arranged in an alternating pattern of one serrated fin on one side and one wave groove on one side. The surface of the flat fins is flat, while the serrated fins have added "tooth-like" protrusions on the original basis. This is equivalent to increasing the surface area of ​​air contact by about 15% to 25% under the same fin spacing. More contact area means that heat can be transferred to the air more quickly.

[0008] Furthermore, the heat dissipation fins are arranged in a linear array on the side of the double-sided shell. The corrugated structure of the fins allows the airflow to flow along the corrugated curve as it passes through, prolonging the contact time between the airflow and the fins and allowing for more thorough heat exchange. The undulation of the corrugations causes continuous velocity changes in the airflow at the crests and troughs, forming more obvious turbulence and further weakening the influence of the thermal boundary layer. The heat dissipation efficiency can be improved by about 20% to 30% compared to flat fins. At the same time, the corrugated structure itself can enhance the mechanical strength of the heat dissipation fins and reduce the deformation of the fins caused by thermal expansion and contraction or external forces, making it suitable for long-term use under high-load conditions.

[0009] Furthermore, several inclined blocks are provided, and several wave grooves are opened and arranged in a linear array on the surface of the heat dissipation fins. The inclined blocks are installed at the top edge of the heat dissipation fin assembly and are inclined upward and outward, which can guide the hot airflow to be discharged smoothly in the upward direction, ensuring that the hot airflow will not accumulate at the top of the lamp body, and the heat dissipation effect will be better.

[0010] Furthermore, the side of the LED core board is provided with components for quick replacement. These components include mounting slots, which are formed on the inner wall of the double-sided shell. A thin sheet of neodymium iron boron magnet is provided on the inner wall of the mounting slot. A pin block is fixedly connected to the side of the LED core board, and an iron sheet is fixedly connected to the side of the pin block away from the LED core board. Several mounting slots are formed on the inner wall of the double-sided shell. A pin block is set at the corresponding position of the LED core board, and an iron sheet is set at the end of the pin block near the mounting slot, giving the pin block a certain magnetic attraction. A thin sheet of neodymium iron boron magnet is provided on the inner wall of the mounting slot. When installing the LED core board, several pin blocks are inserted into the mounting slots, and the iron sheet and the thin sheet of neodymium iron boron magnet attract each other in a clockwise direction, allowing for quick double-sided installation.

[0011] Furthermore, the mounting slots are provided in several pairs and are symmetrical to each other along the vertical central axis of the double-sided shell. The mounting slots are located on the displacement trajectory of the pin blocks. This design is beneficial for corresponding to several pin blocks, so that the pin blocks can be inserted into the mounting slots.

[0012] Furthermore, the thin-film neodymium iron boron magnets are arranged in several pairs in a linear array within the mounting groove. This design facilitates the attraction of several iron sheets into the mounting groove.

[0013] This utility model has the following beneficial effects: This invention enhances the heat dissipation effect by utilizing the interplay between components such as serrated grooves and inclined blocks within the heat dissipation assembly. The serrated grooves increase the air contact area, while the wave grooves extend the airflow contact time and create turbulence, quickly removing the heat generated by the LED core board and improving heat dissipation efficiency. This prevents the lamp from overheating, while the inclined blocks guide the hot airflow smoothly out, preventing heat accumulation at the top of the lamp body and accelerating component aging. This efficient heat dissipation maintains the lamp at a suitable operating temperature, reducing light decay caused by high temperatures and ensuring stable luminous brightness and color temperature.

[0014] This invention facilitates quick replacement of components such as internal iron plates and pin blocks, enabling the disassembly and assembly of LED lamp core boards without additional tools or professional personnel. This is achieved through magnetic plugging and unplugging, significantly shortening maintenance time. The simplified replacement process reduces labor costs and avoids problems such as stripping and wear that may occur with traditional screw fixing methods, thus reducing long-term maintenance costs.

[0017] A double-sided LED light with heat dissipation fins on the top includes a double-sided shell 1, an LED lamp core board 2 on the inner wall of the double-sided shell 1, and a heat dissipation enhancement component 3 on the side of the double-sided shell 1. The heat dissipation enhancement component 3 includes heat dissipation fins 31, the side of the heat dissipation fins 31 is disposed on the double-sided shell 1, the surface of the heat dissipation fins 31 has serrated grooves 32 and wavy grooves 33, and an inclined block 34 is fixedly connected to the side of the heat dissipation fins 31.

[0018] A number of serrated grooves 32 are provided and are arranged in a linear array on the surface of the heat dissipation fins 31. Two LED core boards 2 are provided. Serrated grooves 32 and wave grooves 33 are provided on the surface of the originally flat heat dissipation fins 31. The fins are arranged in an alternating pattern of one serrated groove on one side and one wave groove on one side. The surface of the flat fins is flat, while the serrated fins have added "tooth-like" protrusions on the original basis. This is equivalent to increasing the surface area of ​​air contact by about 15% to 25% under the same fin spacing. More contact area means that heat can be transferred to the air more quickly.

[0019] Several heat dissipation fins 31 are arranged in a linear array on the side of the double-sided shell 1. The corrugated structure of the fins allows the airflow to flow along the corrugated curve as it passes through, prolonging the contact time between the airflow and the fins and allowing for more complete heat exchange. The undulation of the corrugations causes continuous velocity changes in the airflow at the crests and troughs, forming more obvious turbulence and further weakening the influence of the thermal boundary layer. The heat dissipation efficiency can be improved by about 20% to 30% compared to straight fins. At the same time, the corrugated structure itself can enhance the mechanical strength of the heat dissipation fins 31 and reduce the deformation of the fins caused by thermal expansion and contraction or external forces, making it suitable for long-term use under high load conditions.

[0020] Several inclined blocks 34 are provided, and several wave grooves 33 are provided, which are arranged in a linear array on the surface of the heat dissipation fins 31. The inclined blocks 34 are installed on the top edge of the heat dissipation fins 31 group and are inclined upward and outward, which can guide the hot airflow to be discharged smoothly in the upward direction, ensuring that the hot airflow will not accumulate on the top of the lamp body, and the heat dissipation effect will be better.

[0021] The LED core board 2 has a quick-replacement component 4 on its side. The quick-replacement component 4 includes a mounting groove 41, which is opened on the inner wall of the double-sided shell 1. A thin sheet neodymium iron boron magnet 43 is provided on the inner wall of the mounting groove 41. A pin block 42 is fixedly connected to the side of the LED core board 2. An iron sheet 44 is fixedly connected to the side of the pin block 42 away from the LED core board 2. Several mounting grooves 41 are opened on the inner wall of the double-sided shell 1. A pin block 42 is set at the corresponding position of the LED core board 2. An iron sheet 44 is set at the end of the pin block 42 near the mounting groove 41, so that the pin block 42 has a certain magnetic attraction. The thin sheet neodymium iron boron magnet 43 is provided on the inner wall of the mounting groove 41. When installing the LED core board 2, several pin blocks 42 are inserted into the mounting groove 41, corresponding to the mounting groove 41. The iron sheet 44 and the thin sheet neodymium iron boron magnet 43 are attracted in time, and double-sided installation is quickly performed.

[0022] The mounting slots 41 are provided in several pairs and are symmetrical to each other along the vertical central axis of the double-sided outer shell 1. The mounting slots 41 are located on the displacement trajectory of the pin blocks 42. This design is beneficial to correspond to several pin blocks 42 so that the pin blocks 42 can be inserted into the mounting slots 41.

[0023] Several thin-film neodymium iron boron magnets 43 are arranged in pairs and linearly arrayed in the mounting groove 41. This design facilitates the attraction of several iron pieces 44 into the mounting groove 41.

[0024] A specific application of this embodiment is as follows: the double-sided outer shell 1 serves as the supporting and protective structure for the entire lamp. Two LED core boards 2 installed on its inner wall emit light when powered on, generating a large amount of heat. This heat is first transferred to the double-sided outer shell 1. The sides of the double-sided outer shell 1 are connected to a heat dissipation enhancement component 3, composed of several heat dissipation fins 31. The heat is further conducted to the heat dissipation fins 31. At this point, several serrated grooves 32 and wavy grooves 33 on the surface of the heat dissipation fins 31 play a crucial role. They are arranged in an alternating pattern of one side being serrated and the other side being wavy. The serrated groove 32, with its "tooth-like" protrusions, increases the surface area for air contact by approximately 15% to 25% at the same fin spacing, enabling faster heat transfer. The corrugated groove 33, with its wave-like structure, allows airflow to follow a corrugated curve as it passes through, extending the contact time between the airflow and the fins for more thorough heat exchange. It also creates continuous velocity variations at the crests and troughs, resulting in more pronounced turbulence and further weakening the thermal boundary layer effect. This improves heat dissipation efficiency by approximately 20% to 30% compared to straight fins. Furthermore, the corrugated structure of the corrugated groove 33 itself enhances… The mechanical strength of the heat dissipation fins 31 reduces deformation caused by thermal expansion and contraction or external forces, making them suitable for long-term use under high-load conditions. Additionally, several inclined blocks 34 fixedly connected to the side of the heat dissipation fins 31 are installed at the top edge of the fin assembly and tilted upwards and outwards, guiding the hot airflow smoothly upwards and ensuring it doesn't accumulate at the top of the lamp body. Ultimately, through the layered cooperation of the double-sided shell 1, the LED core board 2, and the heat dissipation fins 31, serrated grooves 32, wave grooves 33, and inclined blocks 34 within the enhanced heat dissipation component 3, the lamp's overall performance is ensured. It not only emits light continuously but also achieves efficient heat dissipation. The serrated groove 32 increases the air contact area, and the wave groove 33 extends the airflow contact time and forms turbulence. The heat dissipation efficiency is about 20% to 30% higher than that of flat fins. It can quickly remove the heat generated by the LED core board 2 and prevent the lamp from overheating. At the same time, the inclined block 34 guides the hot airflow to be discharged smoothly, preventing heat accumulation on the top of the lamp body from accelerating the aging of components. Efficient heat dissipation can maintain the LED core board 2 at a suitable temperature, reduce the light decay problem caused by high temperature, ensure the stability of the lamp's brightness and color temperature, and extend the effective service life of the light source.

[0025] The inner wall of the double-sided outer shell 1 has several symmetrical mounting slots (41) arranged in pairs along the vertical central axis. The inner wall of each mounting slot (41) has several thin neodymium iron boron magnets (43) arranged in pairs in a linear array. The side of the LED core board 2 is fixedly connected to several pin blocks (42). The side of each pin block away from the LED core board 2 is fixedly connected to a 44 iron sheet. When installing the LED core board 2, simply align the pin blocks (42) with the corresponding mounting slots (41) on the inner wall of the double-sided outer shell 1 and insert them. At this time, the 44 iron sheets on the pin blocks will engage with the 43 thin neodymium iron boron magnets in the mounting slots (43). The boron magnets quickly attract each other, and the LED core board 2 can be quickly fixed on both sides of the double-sided outer shell 1 by relying on magnetic attraction. When it is necessary to replace the LED core board 2, simply pull the LED core board 2 outward with a little force to separate the 44 iron sheet from the 43 thin neodymium iron boron magnet, and then pull the 42 pin block out of the 41 mounting slot to complete the disassembly. The whole process does not require any additional tools. Relying on the cooperation of the 41 mounting slot, 42 pin block, 43 thin neodymium iron boron magnet, and 44 iron sheet in the 4 easy-to-replace component, the LED core board 2 can be quickly disassembled and replaced, which simplifies the operation steps and improves the replacement efficiency.

[0026] On the inner wall of the double-sided housing 1, several mounting slots 41 are provided in pairs and symmetrically distributed along the vertical central axis. Each mounting slot 41 has several thin neodymium iron boron magnets 43 arranged in pairs in a linear array on its inner wall. On the side of the LED core board 2 to be installed, several pin blocks 42 are fixedly connected. Each pin block 42 has an iron piece 44 fixed to its end away from the LED core board 2. When the LED core board 2 needs to be installed, simply align the pin block 42 on the LED core board 2 with the corresponding mounting slot 41 on the inner wall of the double-sided housing 1 and insert it. The iron piece 44 on the pin block 42 will quickly attract the thin neodymium iron boron magnets 43 in the mounting slot 41. The magnetic attraction quickly completes the double-sided fixation of the LED core board 2 on the double-sided housing 1. The entire installation process is completed in one step. No additional tools are required. When it is necessary to replace the LED lamp core board 2, simply pull the LED lamp core board 2 outward with a little force to separate the iron piece 44 from the thin neodymium iron boron magnet 43, and then pull the pin block 42 out of the mounting slot 41 to complete the disassembly. It is precisely because of the cooperation between the mounting slot 41, pin block 42, thin neodymium iron boron magnet 43, and iron piece 44 in the component 4 that the disassembly and assembly process of the LED lamp core board 2 is simple and quick, which can be completed without professional personnel. This greatly improves the maintenance efficiency of the lamp. No additional tools or professional personnel are required. The disassembly and assembly of the LED lamp core board 2 can be completed by magnetic plugging and unplugging, which greatly shortens the maintenance time. The simplified replacement process reduces labor costs and avoids problems such as stripping and wear that may occur with traditional screw fixing methods, thus reducing long-term maintenance costs.
