Description

Technical Field

[0001] This utility model relates to the field of bulb technology, specifically a rotary-type bulb. Background Technology

[0002] With the continuous development of lighting technology, bulb lamps, as a common lighting device, have been widely used in various fields such as daily life and industrial production.

[0003] Traditional LED bulbs also have limitations in heat dissipation. During operation, LED bulbs generate a significant amount of heat. If this heat cannot be dissipated effectively, the LED chips will overheat, reducing their luminous efficiency and lifespan. Existing heat dissipation structures, such as heat sinks, are often inadequately designed, with limited heat dissipation area and unsatisfactory cooling performance. This problem is particularly pronounced in higher-power LED bulbs. For example, in commercial spaces requiring high-brightness lighting, high-power LED bulbs frequently experience severe light decay due to poor heat dissipation, increasing maintenance costs. Therefore, it is necessary to redesign and modify the cassette-type LED bulb to effectively prevent poor heat dissipation. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model employs a fixed connection between the lamp holder and the heat sink, and a threaded connection between the lamp cover and the heat sink.

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.

[0020] like Figures 1 to 4 As shown, a rotary-type bulb lamp includes a rotary lamp holder 1. A heat sink 2 is fixedly connected to the bottom of the rotary lamp holder 1. A lamp cover 3 is threadedly connected to the bottom of the heat sink 2. A lamp body module 4 is fixedly connected inside the lamp cover 3. A heat-conducting block 5 is fixedly connected to the top of the lamp body module 4. The heat-conducting block 5 is frustum-shaped. A first heat dissipation fin 6 and a second heat dissipation fin 7 are fixedly connected to the surface of the heat-conducting block 5. There are several of the first heat dissipation fins 6 and the second heat dissipation fins 7. The first heat dissipation fins 6 are evenly distributed in a ring on the surface of the heat-conducting block 5. A fan 8 is fixedly connected to the inner wall of the heat sink 2 through a bracket. An air inlet 9 and an air outlet 10 are opened on the surface of the heat sink 2. There are several of both the air inlet 9 and the air outlet 10.

[0021] refer to Figure 2 A flow guide shroud 12 is fixedly connected to the inner wall of the heat sink 2.

[0022] As a technical optimization of this utility model, by setting the air guide shroud 12, the air guide shroud 12 can effectively guide the airflow blown out by the fan 8, so that it flows more concentratedly over the heat conduction block 5 and the surface of the heat dissipation fins, thereby enhancing the airflow and heat dissipation effect, and further improving the heat dissipation performance of the entire bulb lamp.

[0023] refer to Figure 2 The air inlet 9 is fixedly connected to a first dustproof mesh, and the heat sink 2 is fixedly connected to a second dustproof mesh 11.

[0024] As a technical optimization of this utility model, the dual protection of the first dustproof net and the second dustproof net 11 can effectively prevent dust and debris from entering the heat sink 2 and avoid them from adhering to the heat sink fins and fan 8, thereby ensuring the cleanliness of the heat dissipation structure, maintaining a good heat dissipation effect, reducing the failure rate caused by dust accumulation, and extending the maintenance cycle and service life of the bulb lamp.

[0025] refer to Figure 3 A heat dissipation pipe 13 is fixedly connected to the surface of the second heat dissipation fin 7.

[0026] As a technical optimization of this utility model, the application of the heat dissipation pipe 13 can quickly and evenly conduct the heat on the second heat dissipation fin 7 to the entire heat dissipation structure, eliminate local hot spots, make heat dissipation more uniform and efficient, and further improve the working stability and reliability of the lamp module 4.

[0027] refer to Figure 1 The heat sink 2 is made of aluminum, and the lampshade 3 is made of plastic.

[0028] As a technical optimization of this utility model, the heat sink 2 is made of aluminum, which has good thermal conductivity and light weight, so it can quickly conduct heat and is easy to install and use; the lampshade 3 is made of plastic, which has good light transmission and insulation, so as to ensure the lighting effect while providing a safe use environment.

[0029] refer to Figure 3 The shroud 12 is made of plastic, the heat-conducting block 5 and the heat-spreading pipe 13 are both made of beryllium copper, and the first heat dissipation fin 6 and the second heat dissipation fin 7 are both made of copper.

[0030] As a technical optimization of this utility model, the heat guide shroud 12 is made of plastic, which is lightweight and low-cost, while also possessing a certain degree of temperature resistance; the heat conduction block 5 and the heat spreader 13 are made of beryllium copper, which has excellent thermal conductivity and can quickly transfer heat; the first heat dissipation fin 6 and the second heat dissipation fin 7 are made of copper, which has good thermal conductivity and is easy to process and shape. This reasonable combination of materials fully utilizes the advantages of each material, ensuring heat dissipation performance while reducing production costs and improving the product's cost-effectiveness.

[0031] The working principle and usage process of this utility model are as follows: When using this rotary-clamp bulb, firstly, install the rotary-clamp lamp holder 1 onto a suitable lamp interface to complete the fixed installation of the bulb. Next, the lamp body module 4 begins to emit light, generating heat, which is quickly conducted to the frustum-shaped heat-conducting block 5 at its top. At this time, the first heat dissipation fins 6, evenly distributed in a ring on the surface of the heat-conducting block 5, and the fixedly connected second heat dissipation fins 7 begin to function, significantly increasing the heat dissipation area and assisting in heat dissipation. Simultaneously, the fan 8, fixed to the bracket on the inner wall of the heat dissipation cylinder 2, starts operating. Air flows in from the air inlet 9 on the surface of the heat dissipation cylinder 2. The first dustproof mesh inside the air inlet 9 effectively blocks dust and debris from entering. After passing through the fan 8, the air, guided by the air guide shroud 12, flows more concentratedly across the surface of the heat-conducting block 5 and the heat dissipation fins, carrying away heat and dissipating it from the air outlet 10. During this process, the second dustproof mesh 11 inside the heat dissipation cylinder 2 further prevents dust from entering and affecting the heat dissipation effect. The heat dissipation pipe 13 fixed to the surface of the second heat dissipation fin 7 can quickly and evenly conduct heat, eliminating local hot spots and making heat dissipation more efficient. In this way, the entire bulb achieves good heat dissipation through the coordinated work of multiple heat dissipation structures, ensuring the stable operation of the lamp module 4 and extending the life of the LED chips.

[0032] The aforementioned rotary lamp holder 1 and lamp body module 4 are both existing common technologies and are common knowledge to those skilled in the art, and will not be described in detail here. The lamp body module 4 is electrically connected to the rotary lamp holder 1. The circular holes allow air to flow more smoothly between the heat dissipation fins, forming more air channels. When the fan is running, air can enter the interior of the heat dissipation fins through these circular holes, carrying away more heat and thus improving heat dissipation efficiency. Without affecting the basic structure and heat dissipation function of the heat dissipation fins, the presence of the circular holes can reduce the amount of material used in the heat dissipation fins, thereby reducing the weight of the entire bulb and making the installation and use of the bulb more convenient.
