Description

Technical Field

[0001] This utility model relates to the field of LED lamp post technology, and in particular to a waterproof and dustproof LED lamp post. Background Technology

[0002] LED lamp core column is the core component inside an LED lamp that carries and fixes the light-emitting chip and related conductive structure, and provides them with electrical connection and physical support. By integrating circuit connection and structural support functions, it ensures the stable operation of the light-emitting chip. At the same time, it plays a role in connecting various key components and maintaining the overall structural stability inside the lamp. It is an important basic component for realizing the photoelectric conversion and structural integration of LED lamps.

[0003] However, existing lamps are prone to dust accumulation during prolonged use, which reduces their brightness during illumination.

[0004] An existing patent (publication number: CN212080888U) discloses a sealed dustproof lamp core, including a lamp housing, an LED light fixedly mounted on the surface of the lamp housing, a dustproof cover fitted onto the surface of the LED light, an installation hole in the inner wall of the lamp housing, a first sealing gasket fixedly mounted inside the installation hole, a movable groove in the lower end of the lamp housing, a second sealing gasket fixedly mounted inside the movable groove, an adjusting bolt fixedly connected to the upper end of the inner part of the lamp housing, a connecting post screwed to the lower end of the adjusting bolt, and a connecting head fixedly connected to the lower end of the connecting post. This utility model has a simple structure and novel design, effectively ensuring the overall sealing during use, preventing dust from entering, and making cleaning more convenient.

[0005] To address the aforementioned issues, existing patents offer solutions. However, most existing LED lamp posts suffer from a dilemma in balancing waterproofing, dustproofing, and heat dissipation. Either the protective components are not sufficiently sealed, allowing water and dust to easily penetrate, or excessive sealing hinders heat dissipation, leading to excessively high operating temperatures and shortened lifespan. Furthermore, the connection stability between the protective structure and the lamp holder is poor, easily loosening due to installation deviations or external forces, affecting the durability of the protective effect and failing to meet the comprehensive usage requirements of LED lamp posts in complex environments.

[0006] To address this, a waterproof and dustproof LED lamp core column is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a waterproof and dustproof LED lamp post, which can solve the problem that existing LED lamp posts often have the problem of not being able to balance waterproofing and dustproofing with heat dissipation. Either the protective components are not sealed enough, allowing water and dust to easily enter, or the excessive sealing affects heat dissipation, causing the lamp post to operate at too high a temperature and shorten its lifespan. At the same time, the connection stability between the protective structure and the lamp holder is not good, and it is easy to loosen due to installation deviation or external force, affecting the durability of the protective effect and making it difficult to meet the comprehensive use requirements of LED lamp posts in complex environments.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a waterproof and dustproof LED lamp core column, including a lamp holder, a lamp core column structure on the top of the lamp holder, a protective mechanism threadedly connected to the surface of the lamp holder, a sealing ring bonded to the inner wall of the protective mechanism, the surface of the sealing ring engaging with the inner wall of the lamp holder, cooling fins on the surface of the protective mechanism, a protective sleeve on the surface of the lamp holder, the protective mechanism including a glass cover, an aluminum alloy mounting bracket fixedly connected to the bottom of the glass cover, the inner wall of the aluminum alloy mounting bracket threadedly connected to the surface of the lamp holder, a first positioning block fixedly connected to the surface of the aluminum alloy mounting bracket, and the inner wall of the protective sleeve movably connected to the surface of the first positioning block.

[0009] Preferably, a fixing bracket is fixedly connected to the surface of the aluminum alloy mounting bracket, and the surface of the fixing bracket is fixedly connected to the inner wall of the cooling fins.

[0010] Preferably, the inner wall of the fixing frame is provided with a mounting groove for use with the aluminum alloy mounting bracket, and the inner wall of the cooling fins is provided with ventilation holes.

[0011] Preferably, a second positioning block is fixedly connected to the surface of the lamp holder, and the top of the second positioning block contacts the bottom of the first positioning block.

[0012] Preferably, the inner wall of the protective sleeve is movably connected to the surface of the second positioning block, and the inner wall of the protective sleeve is provided with a fixing groove.

[0013] Preferably, the inner wall of the protective sleeve is provided with a through hole, and the protective sleeve is made of rubber.

[0014] Preferably, the inner wall of the aluminum alloy mounting bracket is provided with internal threads, and the surface of the lamp holder is provided with external threads.

[0015] Preferably, the inner wall of the aluminum alloy mounting bracket is provided with a positioning groove for use with the sealing ring, and the inner wall of the lamp holder is provided with a sealing groove for use with the sealing ring.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application incorporates a protective mechanism. The glass cover within the protective mechanism has high light transmittance, ensuring that the lighting effect of the lamp core column structure is not obstructed. The threaded connection between the aluminum alloy mounting bracket and the lamp holder achieves a stable assembly and facilitates subsequent disassembly and maintenance. Its excellent thermal conductivity can efficiently conduct the heat generated by the lamp core column structure during operation. Combined with the cooling fins on the surface, the heat dissipation area is increased, accelerating heat dissipation and preventing high temperatures from affecting the performance of the lamp core column structure. The first positioning block provides installation positioning for the subsequent installation of the protective sleeve, improving the structural stability after assembly.

[0018] 2. By setting a sealing ring and a protective sleeve, the lamp holder provides a stable installation foundation for the lamp core column structure, ensuring its fixed position during operation and preventing the impact of shaking on photoelectric performance. The protective sleeve provides additional protection for the surface of the lamp holder and the connection with the protective mechanism, reducing damage to the lamp holder caused by external environmental erosion, further enhancing the connection firmness after the protective mechanism and the lamp holder are assembled, preventing loosening of the connection due to long-term use or external force, ensuring the protective effect is durable and reliable, thereby extending the overall service life of the lamp core column structure.

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] A waterproof and dustproof LED lamp core column includes a lamp holder 1, a lamp core column structure 3 on the top of the lamp holder 1, a protective mechanism 2 threadedly connected to the surface of the lamp holder 1, a sealing ring 4 bonded to the inner wall of the protective mechanism 2, the surface of the sealing ring 4 engaging with the inner wall of the lamp holder 1, cooling fins 5 on the surface of the protective mechanism 2, a protective sleeve 6 on the surface of the lamp holder 1, the protective mechanism 2 including a glass cover 201, an aluminum alloy mounting bracket 202 fixedly connected to the bottom of the glass cover 201, the inner wall of the aluminum alloy mounting bracket 202 threadedly connected to the surface of the lamp holder 1, a first positioning block 203 fixedly connected to the surface of the aluminum alloy mounting bracket 202, and the inner wall of the protective sleeve 6 movably connected to the surface of the first positioning block 203.

[0029] In this embodiment: by setting up a protective mechanism 2, the glass cover 201 in the protective mechanism 2 has high light transmittance characteristics, which can ensure that the lighting effect of the lamp core column structure 3 is not obstructed. The aluminum alloy mounting bracket 202 and the lamp holder 1 are connected by threads to achieve a stable assembly and facilitate subsequent disassembly and maintenance. Its excellent thermal conductivity can efficiently conduct the heat generated by the lamp core column structure 3 during operation. Combined with the cooling fins 5 on the surface, the heat dissipation area is increased, the heat dissipation is accelerated, and the high temperature is prevented from affecting the performance of the lamp core column structure 3. The first positioning block 203 provides installation positioning for the subsequent installation of the protective sleeve 6, and improves the structural stability after assembly. By setting the sealing ring 4 and the protective sleeve 6, the lamp holder 1 provides a stable installation foundation for the lamp core column structure 3, ensuring that its position is fixed during operation and avoiding the impact of shaking on photoelectric performance. The protective sleeve 6 provides additional protection for the surface of the lamp holder 1 and the connection part with the protective mechanism 2, reducing the damage caused by external environmental corrosion to the lamp holder 1, further enhancing the connection firmness after the protective mechanism 2 and the lamp holder 1 are assembled, preventing the connection from loosening due to long-term use or external force, ensuring the protective effect is durable and reliable, thereby extending the overall service life of the lamp core column structure 3.

[0030] Specifically, such as Figure 4 As shown, a fixing bracket 7 is fixedly connected to the surface of the aluminum alloy mounting bracket 202, and the surface of the fixing bracket 7 is fixedly connected to the inner wall of the cooling fins 5.

[0031] Specifically, such as Figure 4As shown, the inner wall of the fixing frame 7 is provided with a mounting groove 8 that is used in conjunction with the aluminum alloy mounting frame 202, and the inner wall of the cooling fins 5 is provided with ventilation holes 9.

[0032] Specifically, such as Figure 2 As shown, a second positioning block 10 is fixedly connected to the surface of the lamp holder 1, and the top of the second positioning block 10 contacts the bottom of the first positioning block 203.

[0033] In this embodiment: By setting a fixing frame 7, the fixing frame 7 provides a stable mounting carrier for the cooling fins 5. The mounting groove 8 opened in the inner wall of the fixing frame 7 facilitates the fixing frame 7 to be installed on the surface of the aluminum alloy mounting frame 202. The ventilation opening opened in the inner wall of the cooling fins 5 can promote air circulation, accelerate the heat exchange between the cooling fins 5 and the external environment, improve heat dissipation efficiency, and prevent the lamp core column from degrading due to heat accumulation. The contact and cooperation between the second positioning block 10 and the first positioning block 203 further improves the positioning accuracy of the assembly of the protective mechanism 2 and the lamp holder 1, prevents relative displacement between the two, ensures sealing performance and structural stability, and enhances heat dissipation effect and installation reliability.

[0034] Specifically, such as Figure 6 As shown, the inner wall of the protective sleeve 6 is movably connected to the surface of the second positioning block 10, and the inner wall of the protective sleeve 6 is provided with a fixing groove 11.

[0035] Specifically, such as Figure 6 As shown, the inner wall of the protective sleeve 6 is provided with a through hole 12, and the protective sleeve 6 is made of rubber.

[0036] In this embodiment: the fixing groove 11 opened in the inner wall of the protective sleeve 6 can limit the first positioning block 203 and the second positioning block 10 to prevent them from shifting during use, and enhance the protection of the connection between the lamp holder 1 and the protective mechanism 2. The through hole 12 provided in the inner wall of the protective sleeve 6 makes it easy to install the protective sleeve 6 on the surface of the first positioning block 203 and the second positioning block 10. The rubber protective sleeve 6 has good elasticity and sealing performance, can fit tightly with each connecting part, further prevent water and dust from entering, and at the same time buffer external impacts to improve the vibration resistance of the overall structure.

[0037] Specifically, such as Figure 2 , Figure 5 As shown, the inner wall of the aluminum alloy mounting bracket 202 is provided with an internal thread 13, and the surface of the lamp holder 1 is provided with an external thread 14.

[0038] Specifically, such as Figure 2 , Figure 5 As shown, the inner wall of the aluminum alloy mounting bracket 202 is provided with a positioning groove 15 that cooperates with the sealing ring 4, and the inner wall of the lamp holder 1 is provided with a sealing groove 16 that cooperates with the sealing ring 4.

[0039] In this embodiment: the internal thread 13 of the aluminum alloy mounting bracket 202 and the external thread 14 of the lamp holder 1 are matched to achieve precise meshing between the two, ensuring a firm connection and good sealing performance. This facilitates control of the assembly depth to ensure the protective effect. The positioning groove 15 and the sealing groove 16 respectively limit the sealing ring 4, preventing the sealing ring 4 from shifting or deforming during assembly or use. This ensures that the sealing ring 4 can always tightly fill the gap between the aluminum alloy mounting bracket 202 and the lamp holder 1, greatly improving the waterproof and dustproof performance of the connection between the two and ensuring the stable operation of the lamp core column structure 3.

[0040] Working principle: During the use of lamp holder 1, a protective mechanism 2 is set up. The glass cover 201 in the protective mechanism 2 has high light transmittance, which can ensure that the lighting effect of the lamp wick column structure 3 is not obstructed. The aluminum alloy mounting bracket 202 is threadedly connected to the lamp holder 1 to achieve a stable assembly and facilitates subsequent disassembly and maintenance. Its excellent thermal conductivity can efficiently conduct the heat generated by the lamp wick column structure 3 during operation. Combined with the cooling fins 5 on the surface to increase the heat dissipation area, it accelerates heat dissipation and avoids the high temperature from affecting the performance of the lamp wick column structure 3. The first positioning block 203 provides installation positioning for the subsequent installation of the protective sleeve 6. To improve the structural stability after assembly, the lamp holder 1 provides a stable installation base for the lamp core column structure 3 by setting the sealing ring 4 and the protective sleeve 6, ensuring that its position is fixed during operation and avoiding the impact of shaking on photoelectric performance. The protective sleeve 6 provides additional protection for the surface of the lamp holder 1 and the connection part with the protective mechanism 2, reducing the damage caused by external environmental erosion to the lamp holder 1, further enhancing the connection firmness between the protective mechanism 2 and the lamp holder 1 after assembly, preventing the connection from loosening due to long-term use or external force, ensuring the protective effect is durable and reliable, thereby extending the overall service life of the lamp core column structure 3.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
