Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting fixtures, and in particular to an optimized structure for heat dissipation fins in lighting fixtures. Background Technology
[0002] Lighting fixtures are devices used to provide illumination and are widely used in homes, businesses, industries, public facilities, and other fields. They not only meet basic lighting needs but also serve decorative, ambiance-creating, and aesthetic enhancement functions. During use, lighting fixtures often generate a significant amount of heat, requiring heat sinks to dissipate this heat and ensure the internal temperature of the fixture does not become excessively high, thus guaranteeing its normal operation.
[0003] In existing lighting fixtures, the heat sink fins are integrated with the fixture's housing for heat dissipation. However, in current lighting fixtures, the heat sink fins cannot be removed from the main body. When the fins are damaged, they cannot be replaced, affecting the normal operation of the lighting fixture. Furthermore, if there are too many fins, airflow will be obstructed; if there are too few fins, the heat dissipation area will be too small, resulting in mediocre heat dissipation. Utility Model Content
[0004] The main purpose of this invention is to provide an optimized structure for heat dissipation fins in lighting fixtures, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An optimized structure for heat dissipation fins in a lighting fixture includes a heat-conducting mounting sleeve with spiral heat dissipation fins. A fixing sleeve is provided on the top of the heat-conducting mounting sleeve, and a clamping bolt is installed on the fixing sleeve. A flow-blocking structure is provided on the spiral heat dissipation fins.
[0007] Preferably, the lighting body is connected inside the heat-conducting mounting sleeve, and a lampshade is fixed to the lower end of the lighting body, while a threaded connector is provided at the upper end of the lighting body.
[0008] Preferably, the spiral heat dissipation fins are fixed to the outer surface of the heat-conducting mounting sleeve, and the two clamping bolts are threadedly connected to the fixing sleeve, and the clamping bolts are symmetrically arranged on the fixing sleeve.
[0009] Preferably, the flow-blocking structure includes a U-shaped mounting hole, a connecting post, a limiting pressure plate, a fixing plate, a threaded joint, and an L-shaped flow-blocking rod. The U-shaped mounting hole is formed on the spiral heat dissipation fins. The connecting post is fixedly connected to the limiting pressure plate and is located in the U-shaped mounting hole on the spiral heat dissipation fins. The lower end of the connecting post is provided with a connecting screw hole. The limiting pressure plate contacts the upper surface of the spiral heat dissipation fins. The fixing plate is fixedly connected to the threaded joint, and the threaded joint is threadedly connected to the connecting screw hole at the lower end of the connecting post. The threaded joint contacts the lower surface of the spiral heat dissipation fins. The L-shaped flow-blocking rod is fixedly connected to the limiting pressure plate.
[0010] Compared with the prior art, this utility model has the following beneficial effects: The optimized structure of the heat dissipation fins of this lighting fixture, by setting spiral heat dissipation fins on the heat-conducting mounting sleeve, increases the heat dissipation contact area and ensures a large space for heat dissipation, thereby improving the overall heat dissipation effect. At the same time, the spiral heat dissipation fins are installed using the heat-conducting mounting sleeve, the fixing sleeve, and the clamping bolts, which can be quickly disassembled and installed, making it easy to replace and highly flexible in use. The flow obstruction structure set on the spiral heat dissipation fins, using the L-shaped flow obstruction rod, can disrupt the flow of gas in the spiral channel at the spiral heat dissipation fins, forcibly changing the airflow direction and achieving the effect of disrupting the gas boundary layer, further improving the heat dissipation effect. The flow obstruction structure is detachable, making it easy to disassemble and replace. Attached Figure Description

Detailed Implementation
[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] like Figures 1-3As shown, an optimized structure for heat dissipation fins in a lighting fixture includes a heat-conducting mounting sleeve 1, on which spiral heat dissipation fins 2 are provided. A fixing sleeve 3 is located at the top of the heat-conducting mounting sleeve 1, and clamping bolts 4 are installed on the fixing sleeve 3. A flow-blocking structure 5 is provided on the spiral heat dissipation fins 2. The spiral structure of the spiral heat dissipation fins 2 increases the gas flow path and expands the heat dissipation contact area without affecting the spacing between adjacent fins, thus improving the heat dissipation effect and giving the lighting fixture the advantage of efficient heat dissipation during use. A lighting fixture body 6 is connected inside the heat-conducting mounting sleeve 1, and a lampshade 7 is fixed to the lower end of the lighting fixture body 6. A threaded connector 8 is provided at the upper end of the lighting fixture body 6. The spiral heat dissipation fins 2 are fixed to the outer surface of the heat-conducting mounting sleeve 1, and two clamping bolts 4 are threadedly connected to the fixing sleeve 3, with the clamping bolts 4 symmetrically arranged on the fixing sleeve 3. The symmetrically arranged clamping bolts 4 can ensure the effective fixed connection between the fixing sleeve 3 and the lighting body 6. At the same time, the symmetrical arrangement can ensure the uniformity of contact as much as possible, and avoid the heat-conducting mounting sleeve 1 being subjected to uneven lateral force and being in a diagonal state for a long time. This ensures the normal contact installation of the heat-conducting mounting sleeve 1 and ensures the heat dissipation effect.
[0017] When installing the optimized heat sink structure, the thermally conductive mounting sleeve 1 is placed on the lighting body 6, and a clamping bolt 4 is installed on the fixing sleeve 3. The clamping bolt 4 rotates and moves on the fixing sleeve 3 until its end abuts against the lighting body 6, thus completing the installation of the entire optimized heat sink structure. During lighting installation, the lighting body 6 is connected to the connector at the end of the cable using the threaded connector 8. After power is turned on, the LED at the lower end of the lighting body 6 illuminates and emits light, which is diffused through the lampshade 7 while protecting the LED. During use, the heat generated is transferred and diffused to the spiral heat sink 2 through the thermally conductive mounting sleeve 1. External air forms a spiral circulation on the spiral heat sink 2, effectively exchanging heat and dissipating heat from the lighting fixture. During this process, the flow-blocking structure 5 can forcibly change the direction of airflow, disrupting the boundary layer and further improving the heat dissipation effect.
[0018] According to the above implementation scheme, the flow-blocking structure 5 includes a U-shaped mounting hole 501, a connecting post 502, a limiting pressure plate 503, a fixing plate 504, a threaded joint 505, and an L-shaped flow-blocking rod 506. The U-shaped mounting hole 501 is opened on the spiral heat dissipation fin 2. The connecting post 502 is fixedly connected to the limiting pressure plate 503, and the connecting post 502 is located in the U-shaped mounting hole 501 on the spiral heat dissipation fin 2. The lower end of the connecting post 502 is provided with a connecting screw hole. The limiting pressure plate 503 contacts the upper surface of the spiral heat dissipation fin 2. The fixing plate 504 is fixedly connected to the threaded joint 505, and the threaded joint 505 is threadedly connected to the connecting screw hole at the lower end of the connecting post 502. The threaded joint 505 contacts the lower surface of the spiral heat dissipation fin 2. The L-shaped flow-blocking rod 506 is fixedly connected to the limiting pressure plate 503.
[0019] When installing the flow-blocking structure 5, the connecting post 502 is placed into the U-shaped mounting hole 501 on the spiral heat sink fin 2. The limiting pressure plate 503 contacts the upper surface of the spiral heat sink fin 2. The threaded connector 505 on the fixing plate 504 is screwed into the connecting screw hole at the lower end of the connecting post 502 until the fixing plate 504 contacts the spiral heat sink fin 2. Under the combined action of the fixing plate 504 and the limiting pressure plate 503, the connecting post 502 is stably set on the spiral heat sink fin 2, thus completing the installation of the entire flow-blocking structure 5. At this time, the L-shaped flow-blocking rod 506 is displaced between the spiral channels on the spiral heat sink fin 2. When using lighting fixtures, the airflow flows in the spiral channels on the spiral heat sink fin 2. When it encounters the L-shaped flow-blocking rod 506, the spiral flow of gas is forced to change direction, thereby destroying the boundary layer and increasing the heat dissipation effect. When needed, the fixing plate 504 can be removed to remove the entire flow-blocking structure 5 from the spiral heat sink fin 2 for quick replacement. The structure is simple and easy to use.
[0020] It should be noted that by setting spiral heat dissipation fins 2 on the thermally conductive mounting sleeve 1, the spiral structure of the fins increases the heat dissipation contact area and ensures a large space for heat dissipation, thereby improving the overall heat dissipation effect. At the same time, the spiral heat dissipation fins 2 are installed using the thermally conductive mounting sleeve 1, the fixing sleeve 3, and the clamping bolts 4, which can be quickly disassembled and replaced, making it highly flexible in use. The flow obstruction structure 5 is set on the spiral heat dissipation fins 2. The L-shaped flow obstruction rod 506 can disrupt the flow of gas in the spiral channel of the spiral heat dissipation fins 2, forcibly changing the airflow direction and achieving the effect of disrupting the gas boundary layer, further improving the heat dissipation effect. The flow obstruction structure 5 is detachable, making it easy to disassemble and replace.
