Description

Technical Field

[0001] This utility model relates to the field of ceiling light technology, specifically a modular dimmable ceiling light. Background Technology

[0002] Ceiling lights, as important indoor lighting equipment, are widely used in various places such as shopping malls, office buildings, and large exhibition halls. Traditional ceiling lights are mostly limited in function, often only providing basic lighting and failing to meet the diverse lighting needs of different scenarios. As people's requirements for lighting environments continue to increase, dimmable ceiling lights are gradually gaining popularity in the market. By adjusting the brightness and color temperature of ceiling lights, comfortable lighting environments that meet different usage needs can be created.

[0003] However, existing dimmable ceiling lights have many problems in practical applications. On the one hand, their structural design is not reasonable enough, and the overall integration is high, making it difficult to repair and replace parts when a fault occurs. This not only increases maintenance costs but also reduces the efficiency of the ceiling light. On the other hand, poor heat dissipation is a prominent problem. During the dimming process, the internal electronic components and light source of dimmable ceiling lights generate a lot of heat. If the heat cannot be dissipated in time, the internal temperature of the ceiling light will rise, affecting the normal operation of the electronic components, shortening the lifespan of the light source, and even potentially causing safety hazards. For example, under prolonged high-brightness lighting conditions, the LED light source of traditional ceiling lights suffers from poor heat dissipation, resulting in significant light decay, a marked reduction in brightness, and a substantial decrease in lighting effect.

[0004] Therefore, there is an urgent need for a modular dimmable awning light with a reasonable structure, easy maintenance and replacement of parts, and good heat dissipation performance to solve the above-mentioned problems in the existing technology. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a modular dimmable ceiling light that is easy to use and has good heat dissipation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular dimmable ceiling light, including a top cover, a heat dissipation cylinder below the top cover, a lampshade below the heat dissipation cylinder, a lamp body module fixedly connected inside the lampshade, a heat-conducting plate fixedly connected to the top of the lamp body module extending into the heat dissipation cylinder, a heat dissipation fin fixedly connected to the top of the heat-conducting plate, the number of heat dissipation fins being several, the heat dissipation fins being evenly distributed in a ring on the top of the heat-conducting plate, a support frame fixedly connected to the inner wall of the heat dissipation cylinder, a micro motor fixedly connected to the bottom of the support frame, a fan blade rotatably connected inside the support frame, the output end of the micro motor being fixedly connected to the fan blade, an air inlet opening on the top of the top cover, the number of air inlets being several, an air outlet opening on the surface of the lampshade, the number of air outlets being several, the air outlets being evenly distributed in a ring on the surface of the lampshade, and an installation opening on the top of the top cover.

[0008] As a preferred embodiment of this invention, both the air inlet and the air outlet are fixedly connected with dustproof nets.

[0009] As a preferred embodiment of this utility model, a protective cylinder is fixedly connected to the bottom of the lamp body module, and a transparent sheet is fixedly connected inside the protective cylinder.

[0013] 1. This utility model employs a heat-conducting plate and heat dissipation fins on the top of the lamp body module, combined with a micro motor and fan blade structure inside the heat dissipation cylinder, as well as the design of the air inlet on the top cover and the air outlet on the lamp cover, forming a highly efficient heat dissipation circulation system. When the lamp body module generates heat during operation, the heat-conducting plate quickly conducts the heat to the heat dissipation fins. The micro motor drives the fan blades to rotate, accelerating airflow. External cool air enters from the air inlet, passes through the heat dissipation fins to remove heat, and then the hot air is discharged from the air outlet, effectively reducing the lamp body temperature, ensuring the stable operation of electronic components and the light source, extending the service life of the ceiling light, and significantly improving the heat dissipation effect. This device has the advantages of being easy to use and having a good heat dissipation effect.

This utility model utilizes positioning rings at the bottom of the top cover and the top of the lampshade to connect threadedly with positioning grooves at the top and bottom of the heat dissipation cylinder. This design makes the installation and disassembly of the various components of the ceiling light more convenient. During maintenance or replacement of parts, no complex tools are required; components can be separated and assembled simply by turning, greatly reducing maintenance difficulty and improving maintenance efficiency. It also facilitates product transportation and storage, enhancing the practicality and versatility of the ceiling light. Attached Figure Description

[0020] 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.

[0021] like Figures 1 to 4As shown, the modular dimmable ceiling light includes a top cover 1, a heat dissipation cylinder 2 below the top cover 1, a lampshade 3 below the heat dissipation cylinder 2, a lamp body module 4 fixedly connected inside the lampshade 3, a heat-conducting plate 5 fixedly connected to the top of the lamp body module 4 extending into the heat dissipation cylinder 2, and a heat dissipation fin 6 fixedly connected to the top of the heat dissipation plate 5. The heat dissipation fins 6 are numerous and evenly distributed in a ring on the top of the heat dissipation plate 5. A support frame 9 is fixedly connected to the inner wall of the heat dissipation cylinder 2, and a support frame 9 is fixedly connected to the bottom of the support frame 9. The micro motor 10 has a fan blade 11 rotatably connected inside the support frame 9. The output end of the micro motor 10 is fixedly connected to the fan blade 11. The top of the cover 1 has an air inlet 7, and there are several air inlets 7. The surface of the lamp cover 3 has an air outlet 8, and there are several air outlets 8. The air outlets 8 are evenly distributed in a ring on the surface of the lamp cover 3. The top of the cover 1 has an installation port 16. The dimming principle of the lamp module 4 can be PWM (Pulse Width Modulation) dimming. By adjusting the duty cycle of the pulse signal, the average current of the LED is controlled, thereby changing the brightness.

[0022] refer to Figure 4 The bottom of the top cover 1 and the top of the lampshade 3 are both fixedly connected with positioning rings 12, and the top and bottom of the heat sink 2 are both provided with positioning grooves, and the positioning rings 12 are threadedly connected to the positioning grooves.

[0023] As a technical optimization of this utility model, the positioning rings 12 at the bottom of the top cover 1 and the top of the lampshade 3 are threadedly connected to the positioning grooves at the top and bottom of the heat dissipation cylinder 2. This design makes the installation and disassembly of the various components of the ceiling light more convenient. When repairing or replacing parts, no complicated tools are required; the parts can be separated and assembled simply by turning, greatly reducing the difficulty of maintenance, improving maintenance efficiency, and also facilitating the transportation and storage of the product, thus enhancing the practicality and versatility of the ceiling light.

[0024] refer to Figure 4 Dustproof nets 13 are fixedly connected inside both the air inlet 7 and the air outlet 8.

[0025] As a technical optimization of this utility model, the dustproof mesh 13 inside the air inlet 7 and air outlet 8 effectively prevents dust and debris from entering the ceiling light. This avoids dust adhering to components such as the lamp body module 4 and heat dissipation fins 6, preventing dust accumulation from affecting heat dissipation and normal operation of the lamp, reducing the frequency of cleaning and maintenance, ensuring long-term stable operation of the ceiling light, extending the overall service life of the ceiling light, and reducing operating costs.

[0026] refer to Figure 4 A protective cylinder 14 is fixedly connected to the bottom of the lamp body module 4, and a transparent sheet 15 is fixedly connected inside the protective cylinder 14.

[0027] As a technical optimization of this utility model, the protective cylinder 14 at the bottom of the lamp body module 4 and the internal transparent sheet 15 provide physical protection for the lamp body. The protective cylinder 14 can prevent external objects from colliding and damaging the lamp body module 4, while the transparent sheet 15 protects the internal light source without affecting the normal emission of light, ensuring the lighting effect. This protective structure improves the impact resistance of the ceiling light, making it suitable for more complex environments and enhancing the reliability and safety of the ceiling light.

[0028] refer to Figure 2 The top cover 1 and lampshade 3 are both made of iron, while the heat sink 2 and heat sink fins 6 are both made of aluminum.

[0029] As a technical optimization of this utility model, the top cover 1 and lampshade 3 are made of iron, which has high strength and durability, can withstand a certain amount of external force, and protect the internal structure from damage; the heat dissipation cylinder 2 and heat dissipation fins 6 are made of aluminum, which utilizes the good thermal conductivity and light weight of aluminum to reduce the overall weight of the ceiling light while ensuring efficient heat dissipation, making it easier to install and transport, and reducing material costs, thus achieving an optimal balance between performance and cost.

[0030] refer to Figure 1 The surface of lampshade 3 is powder coated.

[0031] As a technical optimization of this utility model, the powder coating treatment on the surface of the lampshade 3 not only makes the lampshade 3 more beautiful and enhances the decorativeness of the ceiling light, but also forms a protective film on the surface of the lampshade 3, which enhances the wear resistance, corrosion resistance and oxidation resistance of the lampshade 3, effectively prevents the surface of the lampshade 3 from rusting and fading, extends the service life of the lampshade 3, and enables the ceiling light to maintain a good appearance and performance for a long time.

[0032] The working principle and usage process of this utility model are as follows: When using this modular dimmable ceiling light, the first step is installation. Align the mounting opening 16 on the top of the upper cover 1 with the installation position on the ceiling, and fix the upper cover 1 to the ceiling using screws or other connectors passing through the mounting opening 16. Next, use the positioning ring 12 at the bottom of the upper cover 1 to connect with the positioning groove at the top of the heat sink 2, installing the heat sink 2 below the upper cover 1; then screw the positioning ring 12 at the top of the lampshade 3 into the positioning groove at the bottom of the heat sink 2, completing the installation of the lampshade 3. This process is simple and convenient, achieving a stable connection of all components without the need for complex tools. The lamp body module 4 is fixed inside the lampshade 3, and its top heat-conducting plate 5 and heat dissipation fins 6 extend into the heat sink 2, laying the foundation for subsequent heat dissipation.

[0033] After installation and commissioning, users can adjust the brightness and color temperature of the lamp module 4 through the dimming control system of the ceiling light according to their actual lighting needs, meeting the lighting requirements of different scenarios. During the operation of the ceiling light, the heat generated by the lamp module 4 is quickly conducted to the heat dissipation fins 6 through the heat conduction plate 5. At this time, the micro motor 10 at the bottom of the support frame 9 on the inner wall of the heat dissipation cylinder 2 drives the fan blades 11 to rotate, accelerating the airflow. External cold air enters the heat dissipation cylinder 2 from the air inlet 7, and carries away the heat as it passes through the heat dissipation fins 6. The hot air is discharged from the air outlets 8 distributed in a ring on the surface of the lampshade 3, forming an efficient heat dissipation cycle, ensuring that the lamp body temperature is maintained within a reasonable range, and ensuring the stable operation of electronic components and light source.

[0034] In daily use, the dustproof mesh 13 inside the air inlet 7 and air outlet 8 effectively prevents dust and debris from entering the ceiling light, reducing heat dissipation problems and lamp malfunctions caused by dust accumulation, and lowering the frequency of cleaning and maintenance. If the lamp body module 4 malfunctions, due to its modular design, the lamp cover 3 can be disassembled by unscrewing the threaded connection between the positioning ring 12 and the positioning groove, allowing for repair or replacement of the lamp body module 4 without disassembling the entire ceiling light, greatly improving maintenance efficiency. Meanwhile, the protective cylinder 14 and transparent sheet 15 at the bottom of the lamp body module 4 effectively prevent damage to the lamp body from external objects, and the transparent sheet 15 does not affect light emission, ensuring lighting effect. Furthermore, the iron material of the top cover 1 and lamp cover 3 ensures structural strength, while the aluminum material of the heat dissipation cylinder 2 and heat dissipation fins 6 balances heat dissipation and lightweight design. The powder coating on the surface of the lamp cover 3 enhances aesthetics and durability, ensuring the ceiling light maintains good performance and appearance during long-term use.
