Description

Technical Field

[0001] This utility model relates to the field of heat dissipation structure technology, and in particular to an active heat dissipation structure for a high-power track spotlight. Background Technology

[0002] Spotlights are used in exhibition halls, stages, and department store display windows to provide illumination and product lighting effects. Due to their high brightness, long lifespan, and status as a new type of green light source, LEDs are increasingly being used in spotlights. However, most LED spotlights have fixed installation positions and cannot achieve lighting at different angles and heights.

[0003] An existing LED track spotlight with authorized publication number CN203036412U includes a lamp body, a spotlight bracket, and a spotlight electrical box. The lamp body includes a lamp holder, an LED light source, a reflector, and a lens. A rotating connection device I is provided between the lamp body and the spotlight bracket, and a rotating connection device II is provided between the spotlight bracket and the spotlight electrical box. Because rotating connection devices are provided between the lamp body and the spotlight bracket, and between the spotlight bracket and the spotlight electrical box, rotation of the lamp body and the spotlight bracket can be achieved. Furthermore, since the LED light source is located on a lamp holder with a heat dissipation structure, and the lamp holder is connected to the lamp body, and the cylindrical outer shell of the lamp body has a ring of heat dissipation fins, heat dissipation can be effectively achieved. This LED track spotlight has a simple structure, low production cost, and solves the problems of existing LED spotlights that cannot be rotated and have poor heat dissipation.

[0004] Regarding the aforementioned technologies, the existing heat dissipation structures have the following drawbacks: medium and high power LED beads continuously generate a large amount of heat when working. If they rely solely on passive conduction by fins, the heat is easily accumulated inside the lamp body, causing the core temperature (junction temperature) to rise rapidly. When the LED junction temperature exceeds the safety threshold, it will directly trigger a vicious cycle of "thermal runaway"—the higher the temperature, the lower the heat dissipation efficiency, which further exacerbates heat accumulation. Therefore, this utility model provides an active heat dissipation structure for high-power track spotlights. Summary of the Invention

[0005] The purpose of this application is to provide an active heat dissipation structure for a high-power track spotlight to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: an active heat dissipation structure for a high-power track spotlight, comprising a spotlight body, wherein an enhanced heat dissipation component is provided on the outer side of the spotlight body; the enhanced heat dissipation component includes multiple slots formed on both sides of the spotlight body, wherein heat-conducting sheets are disposed in the slots, a heat dissipation frame is provided on the outer side of the spotlight body, a heat-conducting rod is provided through the outer side of the heat dissipation frame, and multiple heat dissipation fins are disposed in the heat dissipation frame, wherein the two ends of the heat-conducting rod are respectively attached to the heat dissipation fins and the heat-conducting sheets.

[0007] Preferably, a plurality of first connecting ears are fixedly connected to the outer side of the heat dissipation frame, and a plurality of second connecting ears adapted to the first connecting ears are fixedly connected to the outer side of the spotlight body.

[0008] Preferably, the heat dissipation frame has a slot on its outer side, and a ventilation filter is installed in the slot.

[0009] Preferably, the heat sink frame has ventilation holes on its outer side, and a matching fan is installed in the ventilation holes.

[0010] Preferably, the heat dissipation frame is fixedly connected to a plurality of hanging ears, and the spotlight body is provided with a plurality of heat dissipation holes on the outer side.

[0011] Preferably, the heat dissipation frame has a connecting hole on its outer side, and a matching filter screen is provided in the connecting hole. The filter screen is located on the outer side of the multiple heat dissipation holes.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] In this invention, by strengthening the heat dissipation components, the heat of the spotlight body is quickly guided to the heat dissipation fins through the heat-conducting rod, thereby enhancing the heat conduction and dissipation efficiency of the spotlight body and preventing the core components from failing due to high temperature. In addition, the setting of multiple heat-conducting plates increases the heat dissipation area on the outside of the spotlight body, assisting in the initial diffusion of heat. Furthermore, the setting of the heat dissipation frame enables the fan to achieve centralized cooling of the heat dissipation fins inside the heat dissipation frame. 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. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1: Reference Figure 1-4The diagram illustrates an active heat dissipation structure for a high-power track spotlight. It includes a spotlight body 7, serving as the core load-bearing component and integrating key components such as the light source and circuitry, providing a mounting base for each heat dissipation component. An enhanced heat dissipation assembly is installed on the outer side of the spotlight body 7. Through the coordinated action of multiple components, it enhances the heat conduction and dissipation efficiency of the spotlight body 7, preventing core components from failing due to high temperatures. The enhanced heat dissipation assembly includes multiple slots 12 on both sides of the spotlight body 7 for fixing heat-conducting plates 9, while simultaneously increasing the heat dissipation area on the outer side of the spotlight body 7 to assist in initial heat diffusion. Heat-conducting plates 9 are installed within the slots 12, tightly fitting against the sidewalls of the spotlight body 7 for rapid heat dissipation. The heat dissipation frame 1 quickly absorbs the heat generated inside the spotlight body 7 and conducts it to the heat-conducting rod 8. A heat dissipation frame 1 is provided on the outer side of the spotlight body 7 as an outer support structure to strengthen the heat dissipation components, providing a mounting carrier for components such as the heat-conducting rod 8 and heat dissipation fins 10. Simultaneously, its own structure assists in heat dissipation. A heat-conducting rod 8 is threaded through the outer side of the heat dissipation frame 1, with one end attached to the heat-conducting plate 9 to receive heat, and the other end conducting heat to the heat dissipation fins 10, achieving long-distance heat transfer from the spotlight body 7 to the heat dissipation fins 10. Multiple heat dissipation fins 10 are provided inside the heat dissipation frame 1 to increase the heat dissipation contact area and quickly disperse the heat transferred by the heat-conducting rod 8 into the air. To accelerate heat dissipation, the two ends of the heat-conducting rod 8 are respectively attached to the heat dissipation fins 10 and the heat-conducting plate 9, ensuring a seamless heat transfer path, reducing thermal resistance, and improving heat conduction efficiency. Multiple first connecting ears 5 are fixedly connected to the outer side of the heat dissipation frame 1, which cooperate with second connecting ears 6 to achieve precise docking between the heat dissipation frame 1 and the spotlight body 7. Multiple second connecting ears 6, which are adapted to the first connecting ears 5, are fixedly connected to the outer side of the spotlight body 7. Through assembly with the first connecting ears 5, the heat dissipation frame 1 is stably fixed to the outer side of the spotlight body 7, ensuring a firm connection between the heat dissipation component and the main structure, preventing loosening that could affect the heat dissipation effect. An opening is provided on the outer side of the heat dissipation frame 1. The slot 11 provides installation space for the ventilation filter 2 and also serves as the inlet for air circulation. The ventilation filter 2 is installed inside the slot 11 to filter the air entering the heat sink frame 1, preventing dust and impurities from adhering to the surface of the heat sink fins 10 and avoiding blockage of the heat sink channel, which would reduce the heat dissipation efficiency. Ventilation holes are opened on the outside of the heat sink frame 1 as inlets and outlets for air circulation, forming a heat dissipation airflow channel. A matching fan 4 is installed in the ventilation hole, which drives the airflow by actively rotating, accelerating the discharge of hot air inside the heat sink frame 1 and the entry of cold air from the outside, forming forced convection, which significantly improves the heat dissipation speed and meets the high heat dissipation requirements of high-power spotlights.

[0023] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment also proposes that multiple hanging ears 3 are fixedly connected to the outer side of the heat dissipation frame 1. The hanging ears 3 are used to achieve a stable connection between the heat dissipation frame 1 and the external mounting structure, which facilitates the positioning and fixing of the overall device and ensures that the device is not easily moved during use. Multiple heat dissipation holes 14 are opened on the outer side of the spotlight body 7. The heat dissipation holes 14 can quickly dissipate the heat generated inside the spotlight body 7 during operation, reduce the working temperature of the internal components, and avoid affecting the service life and working stability of the spotlight body 7 due to high temperature. A connecting hole is opened on the outer side of the heat dissipation frame 1. The connecting hole is used to provide a channel for air circulation and assist the heat dissipation inside the heat dissipation frame 1 to dissipate the heat outward. A matching filter screen 13 is set in the connecting hole. The filter screen 13 can block external dust and impurities from entering the interior of the heat dissipation frame 1, prevent dust accumulation from affecting the heat dissipation effect and the normal operation of internal components. The filter screen 13 is set on the outer side of the multiple heat dissipation holes 14, which can filter the air before it enters the heat dissipation holes 14, further improving the protection effect on the interior of the spotlight body 7.

[0024] The working principle of this utility model is as follows: The heat dissipation frame 1 and the spotlight body 7 are connected through the first connecting ear 5 and the second connecting ear 6. The heat of the spotlight body 7 is directed to the heat dissipation fins 10 through the heat conduction rod 8 and the heat conduction plate 9. The fan 4 is controlled to dissipate heat inside the heat dissipation frame 1 and heat dissipation fins 10, thereby accelerating the heat dissipation of the spotlight body 7.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
