Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to a high-power integrated LED lamp. Background Art

[0002] High-power integrated LED lamps refer to lamps that use high-power LEDs as light sources and integrate multiple LED light source modules, drive circuits, heat dissipation systems, etc. into one through integrated design. They have the characteristics of high power, high brightness and high efficiency. Although high-power integrated LED lamps have many advantages, there are still some problems in the use of existing high-power integrated LED lamps. That is, high-power LED lamps will generate more heat during operation. If the heat dissipation system is not designed reasonably or the heat dissipation material performance is poor, it is easy to cause the LED temperature to rise, thereby affecting the luminous efficiency and service life. In addition, some LED lamps may absorb a lot of dust inside when dissipating heat, which will further affect the heat dissipation efficiency of the LED lamp, so further improvement is needed. Utility Model Content

[0003] The main purpose of the present invention is to provide a high-power integrated LED lamp, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A high-power integrated LED lamp, comprising a lamp housing, wherein the upper end of the lamp housing is movably connected to screws on all four sides, the upper end of the lamp housing is fixedly connected to a thermal grease layer, the lamp housing is detachably connected to the lamp heat dissipation structure by four screws, the upper front and upper rear ends of the lamp housing are fixedly connected to magnetic magnets, the inner upper wall of the lamp housing is fixedly connected to the LED lamp body, the lower front and lower rear ends of the lamp housing are both provided with heat dissipation grooves, dust-proof and ventilation structures are respectively clamped in the two heat dissipation grooves, a through insertion cavity is provided at the lower left end of the lamp housing, a light-transmitting plate is inserted in the insertion cavity, and the light-transmitting plate is located on the lower side of the LED lamp body.

[0006] The heat dissipation structure of the lamp includes a copper heat dissipation fin, which is fixedly connected to the upper end of the thermal grease layer 1. The left and right ends of the copper heat dissipation fin are fixedly connected to two ear blocks, and the middle parts of the upper ends of the four ear blocks are each provided with a through screw hole. The middle part of the upper end of the copper heat dissipation fin is fixedly connected to the thermal grease layer 2, and the upper end of the thermal grease layer 2 is fixedly connected to the radiator.

[0007] Preferably, the four screw holes are respectively adapted to the sizes of the four screws, and the copper heat dissipation fin is located between the two magnetic magnets.

[0008] By adopting the above technical solution: the copper heat sink is mainly used to absorb and conduct the heat generated by the lamp. Its good thermal conductivity helps to quickly transfer the heat. The first thermal grease layer is filled between the lamp housing and the copper heat sink, which can enhance the efficiency of heat conduction and reduce thermal resistance. The second thermal grease layer is located between the copper heat sink and the radiator, which can further optimize the effect of heat transfer from the copper heat sink to the radiator. In addition, the radiator can dissipate the heat conducted by the copper heat sink to the surrounding environment, thereby achieving effective heat dissipation of the lamp.

[0009] Preferably, the copper heat dissipation fins are detachably connected to the lamp housing via four ear blocks and four screws.

[0010] By adopting the above technical solution: this detachable connection method is used to facilitate the installation and disassembly of the heat dissipation structure. When the heat dissipation fins are damaged or need maintenance, they can be easily replaced or repaired.

[0011] Preferably, the dustproof ventilation structure includes a dustproof net frame, and the upper front part and the upper rear part of the dustproof net frame are fixedly connected with iron blocks.

[0012] By adopting the above technical solution: the main function of the dustproof net frame is to prevent dust and other impurities from entering the interior of the lamp, while not affecting the circulation of air, thereby ensuring ventilation effect.

[0013] Preferably, the two dustproof net frames are distributed in left and right mirror images, and the sizes of the dustproof net frames match those of the heat dissipation slots.

[0014] By adopting the above technical solution: two dustproof net frames distributed in left and right mirror images, this symmetrical distribution method can more comprehensively cover the heat sink, ensuring that dust entering from all directions can be effectively blocked, while ensuring uniform ventilation. The dustproof net frame matches the size of the heat sink, so that the dustproof net frame can be installed exactly at the heat sink, without gaps causing dust to enter, and without affecting the ventilation effect due to size mismatch, thereby achieving efficient dustproof and ventilation functions, and providing good environmental conditions for normal heat dissipation and stable operation of the lamp.

[0015] Preferably, the dustproof net frame is inserted into the heat dissipation slot, and the dustproof net frame is magnetically connected to the magnetic magnet through two iron blocks, and the dustproof net frame is communicated with the interior of the lamp housing.

[0016] By adopting the above technical solution: the dustproof net frame plays a dual role of dust prevention and ventilation, preventing dust from entering the inside of the lamp housing, while allowing air circulation to assist in heat dissipation. The iron block cooperates with the magnetic magnet to achieve rapid installation and fixation of the dustproof net frame, ensuring that it will not loosen or fall off when the lamp is working, and also facilitating the installation and disassembly of the dustproof net frame. In addition, the dustproof net frame is connected to the inside of the lamp housing, ensuring air exchange between the inside of the lamp and the outside world, helping to dissipate the heat generated by the lamp while effectively blocking dust.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, copper heat dissipation fins are used as the main heat dissipation elements. Due to its high thermal conductivity, copper can quickly transfer the heat generated inside the lamp to the heat dissipation fins with a larger area, and then effectively dissipate it to the environment through air convection or radiation, which greatly reduces the working temperature of the lamp. A first thermal grease layer is provided between the copper heat dissipation fins and the LED lamp housing, and a second thermal grease layer is provided between the copper heat dissipation fins and the radiator, so that these two layers of thermal grease can fill the tiny gaps between the contact surfaces, reduce thermal resistance, improve heat conduction efficiency, and ensure that heat can be smoothly transferred from the heat source to the heat dissipation fins and the radiator. The heat dissipation structure and the lamp housing can be detachably connected by four ear blocks and four screws, which is convenient for personnel to install and disassemble the heat dissipation structure, and also convenient for later maintenance and replacement. Therefore, the working temperature inside the lamp is reduced through effective heat dissipation design.

[0019] 2. In the utility model, the dust-proof net frame can effectively prevent external dust, insects and other impurities from entering the interior of the lamp by being provided with a dust-proof net frame. The size of the dust-proof net frame is matched with that of the heat dissipation slot, and the plug-in method ensures good sealing and prevents dust and other impurities from penetrating from the gap. At the same time, the mesh structure of the dust-proof net frame ensures good ventilation without affecting the heat dissipation effect of the lamp, thereby achieving the dual functions of dustproof and ventilation. The magnetic adsorption connection between the iron block and the magnetic magnet not only provides a convenient installation method, but also enhances the stability of the dust-proof net frame in the heat dissipation slot, avoids loosening or falling off due to vibration or external force, and ensures the stable operation of the lamp.

[0028] See also Figure 1-4 , the utility model provides a technical solution:

[0029] A high-power integrated LED lamp comprises a lamp housing 1, the upper end of the lamp housing 1 is movably connected with screws 2 on all sides, the upper end of the lamp housing 1 is fixedly connected to a thermal grease layer 3, the lamp housing 1 is detachably connected to a lamp heat dissipation structure 4 by four screws 2, the upper front and upper rear ends of the lamp housing 1 are fixedly connected to a magnetic magnet 7, the inner upper wall of the lamp housing 1 is fixedly connected to an LED lamp body 10, the lower front and lower rear ends of the lamp housing 1 are provided with heat dissipation grooves 8, and dust-proof ventilation structures 9 are respectively clamped in the two heat dissipation grooves 8, a through insertion cavity 5 is provided at the lower left end of the lamp housing 1, a light-transmitting plate 6 is inserted in the insertion cavity 5, and the light-transmitting plate 6 is located on the lower side of the LED lamp body 10.

[0030] In this embodiment, the lamp heat dissipation structure 4 includes a copper heat dissipation fin 41, which is fixedly connected to the upper end of the thermal grease layer 3. The left and right ends of the copper heat dissipation fin 41 are fixedly connected to two ear blocks 42, and the middle parts of the upper ends of the four ear blocks 42 are each provided with a through screw hole 43. The middle part of the upper end of the copper heat dissipation fin 41 is fixedly connected to the thermal grease layer 2 44, and the upper end of the thermal grease layer 2 44 is fixedly connected to the radiator 45. The four screw holes 43 are respectively adapted to the sizes of the four screws 2. The copper heat dissipation fin 41 is located between the two magnetic magnets 7. The copper heat dissipation fin 41 is detachably connected to the lamp housing 1 through the four ear blocks 42 and the four screws 2.

[0031] Through the above scheme: the LED lamp body 10 will generate heat when working. The heat is first quickly conducted to the copper heat sink fin 41 through the thermal grease layer 3. Due to its good thermal conductivity, the copper heat sink fin 41 can quickly absorb and disperse the heat. Then, the heat is further conducted to the radiator 45 through the thermal grease layer 44 on the upper end of the copper heat sink fin 41. The radiator 45 increases the contact area with the air, so that the heat can be effectively dissipated into the surrounding environment. In addition, the lamp housing 1 will also absorb part of the heat and exchange heat with the outside air through its outer surface to assist in heat dissipation. At the same time, the copper heat sink fin 41 is detachably connected to the lamp housing 1 through the ear block 42 and the screw 2. This connection method can not only ensure good heat conduction, but also facilitate disassembly and maintenance by personnel, thereby achieving effective heat dissipation of the LED lamp body 10 and ensuring the normal operation and service life of the lamp.

[0032] In this embodiment, the dustproof ventilation structure 9 includes a dustproof net frame 91, and the upper front and upper rear parts of the dustproof net frame 91 are fixedly connected with iron blocks 92. The two dustproof net frames 91 are distributed in left and right mirror images. The dustproof net frame 91 matches the size of the heat dissipation slot 8. The dustproof net frame 91 is inserted into the heat dissipation slot 8. The dustproof net frame 91 is magnetically adsorbed and connected to the magnetic magnet 7 through two iron blocks 92 respectively, and the dustproof net frame 91 is connected to the interior of the lamp housing 1.

[0033] Through the above scheme: the LED lamp body 10 generates heat when working, and the heat will be transferred to the heat dissipation groove 8 through the lamp housing 1. Since the dust-proof net frame 91 matches the size of the heat dissipation groove 8 and is inserted into it, and is connected to the interior of the lamp housing 1, air can enter the interior of the lamp housing 1 through the dust-proof net frame 91, and the dust-proof net on the dust-proof net frame 91 can prevent dust and other impurities from entering the interior of the lamp housing 1, thereby realizing the dust reduction function. The other two dust-proof net frames 91 distributed in left and right mirror images increase the ventilation area and improve the ventilation efficiency, so that the air entering the interior of the lamp housing 1 absorbs heat and is discharged from the heat dissipation groove 8 with the heat, thereby realizing ventilation and heat dissipation of the lamp, and the dust-proof net frame 91 is magnetically adsorbed and connected to the magnetic magnet 7 through the iron block 92. This connection method ensures the stable installation of the dust-proof net frame 91 and is easy to disassemble and clean.

[0034] It should be noted that the present invention is a high-power integrated LED lamp. During use, the LED lamp body 10 generates heat when it is working. The heat is first transferred to the lamp housing 1. The thermal grease layer 3 on the lamp housing 1 enhances the efficiency of heat conduction to the lamp heat dissipation structure 4. The heat will be conducted from the thermal grease layer 3 to the copper heat dissipation fin 41. The copper heat dissipation fin 41 quickly absorbs and disperses the heat due to its good thermal conductivity. Then, the heat is further conducted to the radiator 45 through the thermal grease layer 2 44. The radiator 45 dissipates the heat into the air due to its large contact area with the surrounding air. At the same time, the hot air inside the lamp housing 1 needs to be discharged, and the cold air will pass through the dustproof mesh frame. 91 enters the interior of the lamp housing 1, the dustproof net frame 91 can prevent dust from entering, and the two dustproof net frames 91 distributed in left and right mirror images increase the ventilation volume. In addition, the dustproof net frame 91 is plugged into it by matching the size of the heat dissipation slot 8, and the magnetic adsorption of the iron block 92 and the magnetic magnet 7 can be used to achieve a stable installation with the lamp housing 1, so that it is convenient for personnel to subsequently disassemble and clean the dust attached to the dustproof net frame 91, and a light-transmitting plate 6 is inserted in the insertion cavity 5 at the lower left end of the lamp housing 1, which can be used to transmit the light emitted by the LED lamp body 10. Therefore, through the synergistic effect of the above-mentioned components, the efficient heat dissipation, dustproof and light transmission functions of the lamp are realized, ensuring the normal and stable operation of the lamp.
