Description

Technical Field

[0001] This application relates to the technical field of lighting fixtures, and in particular to a light-sensing LED lamp with automatically adjustable brightness. Background Technology

[0002] With the popularization of LED lighting technology, light-sensitive automatic dimming LED lights are widely used in various lighting scenarios due to their energy-saving, environmentally friendly, intelligent and convenient characteristics.

[0003] Traditional LED lights are typically installed and fixed using bolts or clips, which results in cumbersome assembly and disassembly processes and poor adjustment flexibility. This inflexibility is particularly problematic in applications requiring frequent relocation or maintenance, significantly reducing efficiency. Furthermore, the substantial heat generated by LED lights during prolonged operation places high demands on heat dissipation. While common cooling fan designs with direct exhaust vents can accelerate airflow, they are prone to drawing in dust in dusty environments due to negative pressure. This leads to dust accumulation on fan blades, reduced heat dissipation efficiency, and even damage to internal components, severely impacting the lifespan and stability of the light fixture. Although existing technologies offer localized improvements to fixing or heat dissipation, a comprehensive solution that organically combines a convenient and adjustable mechanical fixing mechanism with an efficient dustproof heat dissipation design is lacking. This makes it difficult to simultaneously meet users' needs for installation flexibility, maintenance convenience, and long-term operational reliability.

[0004] To address the above problems, this utility model proposes a light-sensing LED lamp with automatically adjustable brightness. Utility Model Content

[0005] To address the problems mentioned in the background section, this application provides a light-sensitive LED lamp with automatically adjustable brightness.

[0006] This application provides a light-sensing LED lamp with automatically adjustable brightness, employing the following technical solution:

[0007] Optionally, the main body includes a fixing structure, and a heat dissipation structure is provided below the fixing structure;

[0008] The fixing structure includes a fixing column, a slot is provided on the outer side of the fixing column, a locking block is movably sleeved inside the slot, a moving block is provided on one side of the locking block, a fixing block is provided on one side of the moving block, and wedge blocks are provided on both sides of the fixing block.

[0009] The heat dissipation structure includes a cooling fan, a fan cover is provided on the outside of the cooling fan, and an air outlet is provided on one side of the fan cover.

[0010] Optionally, the slot of the fixing post matches the protrusion of the locking block to enhance locking stability.

[0011] Optionally, the wedge block can be adjusted to lock or release the locking block from the slot by adjusting the position of the moving block, thus forming an adjustable fixing mechanism.

[0012] Optionally, the fixing column is made of high-strength alloy steel and its surface is treated with rust prevention.

[0013] Optionally, the air outlet has an upward-sloping structure to prevent dust from entering the interior.

[0014] Optionally, the airflow direction of the cooling fan is consistent with the tilt direction of the air outlet.

[0015] Optionally, the displacement of the wedge block drives the moving block to press the locking block, causing the locking block to extend radially out of the slot to form a locking state.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] 1. The fixed structure uses a moving block to drive a wedge block, controlling the radial expansion and contraction of the locking block within the slot of the fixed column, achieving rapid locking or releasing. This simplifies the installation and disassembly process and significantly enhances connection stability through the mechanical self-locking effect of the wedge surface and the locking block, effectively avoiding the risk of loosening and falling off during the use of the lamp.

[0018] 2. The upward-sloping air outlet of the heat dissipation structure, combined with the airflow guidance of the cooling fan, efficiently dissipates heat while forming a physical barrier, significantly preventing dust from flowing back into the interior from the air outlet. This reduces the probability of decreased heat dissipation efficiency or circuit failure due to dust accumulation. In terms of materials and manufacturing processes, the mounting posts are made of high-strength alloy steel with rust-proof treatment, ensuring that load-bearing components are corrosion-resistant and wear-resistant in humid environments, extending the overall structural lifespan. In summary, this LED light integrates convenient installation and disassembly, high stability, active dust prevention, and long-term heat dissipation, meeting the installation needs of diverse scenarios while reducing maintenance costs at the source, ultimately achieving product excellence.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a light-sensitive LED lamp with automatically adjustable brightness. For example... Figure 1-5 As shown, the main body 1 includes a fixing structure 2, and a heat dissipation structure 3 is provided below the fixing structure 2;

[0027] The fixed structure 2 includes a fixed column 201. A slot 202 is provided on the outer side of the fixed column 201. A locking block 203 is movably sleeved inside the slot 202. A moving block 204 is provided on one side of the locking block 203. A fixed block 205 is provided on one side of the moving block 204. Wedge blocks 206 are provided on both sides of the fixed block 205.

[0028] The heat dissipation structure 3 includes a heat dissipation fan 301, a fan cover 302 is provided on the outside of the heat dissipation fan 301, and an air outlet 303 is provided on one side of the fan cover 302.

[0029] It should be noted that the fixing structure 2 drives the wedge block 206 through the moving block 204, controlling the radial extension and retraction of the locking block 203 within the fixing post 201 and the slot 202, forming an adjustable mechanical locking mechanism. This enables quick assembly and disassembly of the lamp, and the wedge block 206 and locking block 203 enhance installation stability, avoiding the risk of loosening. Simultaneously, the high-strength, rust-resistant alloy steel fixing post 201 ensures the durability of load-bearing components in humid environments. The heat dissipation structure 3 utilizes the upwardly designed air outlet 303 and the airflow guidance of the cooling fan 301 to efficiently dissipate heat and prevent dust backflow through physical barriers, reducing the decrease in heat dissipation efficiency or circuit failure caused by dust accumulation, thereby improving the long-term operational reliability of the lamp.

[0030] Please see Figure 4-5 The slot 202 of the fixing post 201 matches the protrusion of the locking block 203, enhancing the locking stability.

[0031] It should be noted that when locked, the locking block 203 forms a stable fit with the slot 202, and the mechanical self-locking effect enhances the anti-loosening ability of the fixed structure 2, thereby enhancing the overall installation reliability and load-bearing stability.

[0032] Please see Figure 4-5The wedge block 206 locks or releases the locking block 203 and the slot 202 by adjusting the position of the moving block 204, forming an adjustable fixing mechanism.

[0033] It should be noted that the moving block 204 drives the wedge block 206 to move, and the mechanical properties of the wedge-shaped inclined surface are used to convert the linear motion into the radial expansion and contraction of the locking block 203, so as to achieve rapid locking and release. At the same time, the self-locking effect of the wedge structure is used to improve the fixation reliability and prevent the lamp from loosening during use.

[0034] Please see Figure 4 The fixed column 201 is made of high-strength alloy steel and its surface is treated with rust prevention.

[0035] It should be noted that the fixing column 201, through the dual protection of material strength and surface protection, ensures the long-term stability of the fixing structure 2 in terms of load-bearing, resistance to mechanical stress and humid environment, thereby improving the overall service life of the lamp.

[0036] Please see Figure 1-2 The air outlet 303 has an upward-sloping structure to prevent dust from entering the interior.

[0037] It should be noted that the air outlet 303 prevents external dust from flowing back into the lamp. Its upward-sloping opening, combined with the airflow guidance of the cooling fan 301, forms a barrier while efficiently expelling hot air. By utilizing the airflow direction and gravity, it prevents dust from reversing its intrusion from the air outlet 303, thereby protecting internal components from dust accumulation and ensuring heat dissipation efficiency and the long-term stability of the equipment.

[0038] Please see Figure 1-3 The airflow direction of the cooling fan 301 is consistent with the tilt direction of the air outlet 303.

[0039] It should be noted that the airflow direction of the cooling fan 301 is consistent with the tilt direction of the upward-sloping air outlet 303, forming a directional airflow channel. While efficiently dissipating heat, it uses the positive pressure of the airflow to prevent external dust from flowing back in, thus balancing heat dissipation efficiency and dust prevention effect.

[0040] Please see Figure 5 The displacement of the wedge block 206 drives the moving block 204 to press the locking block 203, causing the locking block 203 to extend radially out of the slot 202 to form a locked state.

[0041] It should be noted that the displacement of the wedge block 206 is converted into radial compression of the locking block 203, causing the locking block 203 to extend from the slot 202 of the fixing post 201 and lock with the external mounting structure, thereby achieving fast and stable fixing of the lamp. At the same time, the structure can be conveniently released from the locking state through reverse operation.

[0042] The implementation principle of an automatically adjustable brightness light-sensing LED lamp according to an embodiment of this application is as follows: A fixing post 201 is vertically installed on the top of the lamp body 1, and a locking block 203 is movably fitted into a slot 202 on its outer side. A moving block 204 is connected to one side of the locking block 203, and the end of the moving block 204 is fixed to the fixing block 205. Wedge-shaped blocks 206 symmetrically arranged on both sides of the fixing block 205 contact the inclined surfaces of the locking block 203. During installation, pushing the moving block 204 causes the fixing block 205 to move axially. At this time, the inclined surfaces of the wedge-shaped blocks 206 press against the locking block 203, forcing it to extend radially out of the slot 202 and lock with the external mounting base. When the fixing block 205 is moved in the opposite direction, the wedge-shaped blocks 206 release pressure, and the locking block 203 retracts into the slot 202 to achieve disassembly. The fixing post 201 is made of high-strength alloy steel and is rust-proofed. The slot 202 matches the protruding contour of the locking block 203 to ensure locking stability.

[0043] The cooling fan 301 is embedded in the bottom of the main body 1 and covered by a fan cover 302. The air outlet 303 on one side of the fan cover 302 is designed with an upward-sloping structure, and its tilt direction is completely consistent with the axial airflow discharge direction of the cooling fan 301. When the fan is running, the airflow is ejected at high speed along the upward-sloping path, forming a positive air pressure barrier at the air outlet 303, effectively preventing external dust from flowing back into the lamp due to negative pressure, while improving the efficiency of hot airflow discharge.

[0044] During installation, the wedge block 206 is driven by adjusting the moving block 204, causing the locking block 203 to expand radially and lock the installation position; disassembly is achieved by reversing the operation to quickly release the lock. During operation, the cooling fan 301 directs heat out from the upward-sloping exhaust port 303, and the dustproof structure reduces the risk of dust accumulation. The adjustability of the fixing structure 2 and the dustproof characteristics of the cooling structure 3 work synergistically to balance ease of installation, mechanical stability, and long-term heat dissipation reliability.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
