[0001] This utility model relates to the field of LED lighting fixture technology, and in particular to an assembled LED lighting fixture for dome theaters. Background Technology
[0002] In the lighting system of a dome theater, LED light fixtures are a key component, used to provide uniform and appropriate lighting for the theater;
[0003] Traditional lighting fixtures typically employ welding or integrated designs. This design necessitates cutting and disassembly when components are damaged or maintenance / upgrades are required on-site. The disassembly process is extremely cumbersome and complex, often requiring specialized tools and time, severely impacting cinema operations and increasing maintenance costs. Furthermore, with the increasing use of high-power LED lights in dome theaters, heat generation has become a significant issue. Traditional lighting fixtures lack effective heat dissipation measures, leading to accelerated light decay and shortened lifespan of LED lights due to overheating. This affects the stability and continuity of lighting effects and reduces the overall lifespan of the LED lights. Utility Model Content

[0005] The dome theater assembled LED light stand provided by this utility model includes: a connecting component, a horizontal support rod, a vertical support rod, and a heat dissipation component. The connecting component includes a fixing box, a movable clamp, and a screw. There are three sets of fixing boxes, one set of vertical fixing boxes and two sets of horizontal fixing boxes. A set of horizontal fixing boxes is fixedly connected to each side of the vertical fixing box. The fixing box has an insertion groove and a sliding groove inside. The movable clamp is slidably connected in the sliding groove inside the fixing box. The outer surface of the movable clamp has a through hole, and the screw is movably installed in the through hole. A horizontal support rod is provided on one side of the connecting component. A heat dissipation component is provided on the upper surface of the horizontal support rod. A vertical support rod is provided above the connecting component.
[0006] Preferably, the fixing box has an inlet / outlet groove on each side, and the inlet / outlet groove on both sides of the fixing box is connected to the insertion groove and sliding groove inside the fixing box. A through hole is opened on the outer surface of one end of the fixing box, and the through hole is connected to the sliding groove inside the fixing box. Two sets of telescopic holes are opened on the inner wall of the sliding groove inside the fixing box, and a threaded hole is opened on the inner wall of the sliding groove inside the fixing box, with the threaded hole located between the two sets of telescopic holes.
[0007] Preferably, the movable clamp is fixedly connected to two sets of telescopic rods on the side of the inner wall of the inner slide groove of the fixed box. The outer surface of the two sets of telescopic rods is respectively fitted with springs, and the ends of the two sets of telescopic rods away from the movable clamp are respectively slidably disposed inside the two sets of telescopic holes on the inner wall of the inner slide groove of the fixed box.
[0008] Preferably, one end of the screw passes through the through hole on the outer surface of the movable clamp and is threaded into the threaded hole on the inner wall of the sliding groove inside the fixed box. The other end of the screw is fixedly connected to a knob. The end of the knob away from the screw passes through the through hole on the outer surface of one end of the fixed box and extends to the outer surface of the fixed box. The end of the knob extending to the outer surface of the fixed box has an internal hexagonal groove.
[0009] Preferably, the heat dissipation assembly includes a heat-conducting plate, heat dissipation fins, and a heat dissipation fan. The lower end of the heat-conducting plate is fixedly connected to the upper surface of the horizontal support rod. Several sets of heat dissipation fins are fixedly connected to one side of the heat-conducting plate, and a heat dissipation fan is fixedly connected to one side of the heat-conducting plate. The heat dissipation fan is located on the side of the heat dissipation fins.
[0010] Preferably, both ends of the horizontal support rod are fixedly connected with insertion strips, which are inserted into the insertion slots of the horizontal fixing box, and one side of the movable clamp is clamped on the outer surface of the insertion strip. Similarly, both the upper and lower ends of the vertical support rod are fixedly connected with insertion strips, which are inserted into the insertion slots of the vertical fixing box, and one side of the movable clamp is clamped on the outer surface of the insertion strip.
[0011] Compared with related technologies, the dome theater assembled LED light stand provided by this utility model has the following advantages:
[0012] Beneficial effects:
[0013] 1. The system is equipped with connecting components, a horizontal support rod, and a vertical support rod. The insertion strips at both ends of the horizontal support rod are inserted into the insertion slots of the horizontal fixing box, and the insertion strips at both ends of the vertical support rod are inserted into the insertion slots of the vertical fixing box. At this point, the movable clamp is in its initial position under the action of the spring and the telescopic rod. By rotating the knob, the knob drives the screw to rotate. When the screw rotates, it engages with the threaded hole on the inner wall of the sliding groove inside the fixing box, allowing the screw to enter the threaded hole. Simultaneously, the knob moves with the screw, pushing the movable clamp to slide along the sliding groove towards the insertion strip. Under the push of the knob, the movable clamp tightly clamps the insertion strip, ensuring a stable connection between the horizontal and vertical support rods. When disassembly is required, simply use a simple tool to rotate the knob and drive the screw to easily release the movable clamp from the insertion strip, quickly separating the components. This eliminates the need for complex cutting and disassembly procedures, significantly shortening maintenance and repair time, reducing reliance on professional technicians, and effectively lowering maintenance costs.
[0014] 2. With the heat dissipation components, the heat generated by the LED light during operation is transferred to the heat dissipation fins through the heat conduction plate. The heat dissipation fins use their large surface area to exchange heat with the surrounding air. After the cooling fan is started, the airflow is accelerated, which quickly blows away the hot air around the heat dissipation fins. Cold air is continuously replenished, continuously removing heat and maintaining the LED light within a suitable operating temperature range. This effectively slows down the light decay of the LED light and effectively extends its service life. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The assembly includes: a connecting component 1, a horizontal support rod 2, a vertical support rod 3, and a heat dissipation component 4. The connecting component 1 includes a fixed box 5, a movable clamp 6, and a screw 7. There are three sets of fixed boxes 5, one set of fixed boxes 5 being vertical and two sets of fixed boxes 5 being horizontal. A set of horizontal fixed boxes 5 is fixedly connected to each side of the vertical fixed box 5. The fixed box 5 has an insertion groove and a sliding groove inside. The movable clamp 6 is slidably connected to the sliding groove inside the fixed box 5. The outer surface of the movable clamp 6 has a through hole, and the screw 7 is movably installed inside the through hole. The screw 7 can rotate and slide inside the through hole on the outer surface of the movable clamp 6. A horizontal support rod 2 is provided on one side of the connecting component 1. A heat dissipation component 4 is provided on the upper surface of the horizontal support rod 2. The heat dissipation component 4 is used to dissipate heat from the installed LED lights. A vertical support rod 3 is provided above the connecting component 1. A complete LED light frame can be formed by connecting and combining several sets of connecting components 1, horizontal support rods 2, and vertical support rods 3.
[0022] In the specific implementation process, the fixed box 5 has an inlet and outlet groove on both sides, which facilitates the installation and connection of the horizontal support rod 2 and the vertical support rod 3. The inlet and outlet grooves on both sides of the fixed box 5 are connected to the insertion groove and sliding groove inside the fixed box 5. A through hole is opened on the outer surface of one end of the fixed box 5, which is connected to the sliding groove inside the fixed box 5. Two sets of expansion holes are opened on the inner wall of the sliding groove inside the fixed box 5, and a threaded hole is opened on the inner wall of the sliding groove inside the fixed box 5. The threaded hole is located between the two sets of expansion holes.
[0023] Two sets of telescopic rods 8 are fixedly connected to the side of the movable clamp 6 near the inner wall of the inner slide groove of the fixed box 5. Springs 9 are respectively sleeved on the outer surface of the two sets of telescopic rods 8. The ends of the two sets of telescopic rods 8 away from the movable clamp 6 are respectively slidably set inside the two sets of telescopic holes in the inner wall of the inner slide groove of the fixed box 5. When the movable clamp 6 approaches the inner insertion slot of the fixed box 5, the telescopic rods 8 enter the two sets of telescopic holes in the inner wall of the inner slide groove of the fixed box 5. At the same time, the springs 9 are compressed and generate elastic force. When the movable clamp 6 is reset, the elastic force of the springs 9 pushes the movable clamp 6 to reset.
[0024] One end of the screw 7 passes through the through hole on the outer surface of the movable clamp 6 and is threaded into the threaded hole on the inner wall of the slide groove inside the fixed box 5. The other end of the screw 7 is fixedly connected to a knob 10. The end of the knob 10 away from the screw 7 passes through the through hole on the outer surface of one end of the fixed box 5 and extends to the outer surface of the fixed box 5. The end of the knob 10 extending to the outer surface of the fixed box 5 has an internal hexagonal groove. The knob 10 allows the user to manually apply force to rotate the screw 7. The internal hexagonal groove on the end of the knob 10 extending to the outer surface of the fixed box 5 makes it easy to use an internal hexagonal wrench to rotate the knob 10, thereby causing the knob 10 to drive the screw 7 to rotate. When the screw 7 rotates, it is threaded into the threaded hole on the inner wall of the slide groove inside the fixed box 5. At the same time, the screw 7 enters the threaded hole on the inner wall of the slide groove inside the fixed box 5. When the screw 7 enters the threaded hole on the inner wall of the slide groove inside the fixed box 5, the movable clamp 6 is pushed to slide along the slide groove inside the fixed box 5 by the knob 10.
[0025] The heat dissipation component 4 includes a heat-conducting plate 11, heat dissipation fins 12, and a cooling fan 13. The lower end of the heat-conducting plate 11 is fixedly connected to the upper surface of the horizontal support rod 2. During LED lamp installation, the back of the LED lamp is attached to the outer surface of the heat-conducting plate 11, so that the heat generated by the LED lamp during operation can be transferred to the heat-conducting plate 11. Several sets of heat dissipation fins 12 are fixedly connected to one side of the heat-conducting plate 11. Both the heat-conducting plate 11 and the heat dissipation fins 12 are made of metal materials with good heat dissipation, such as copper. The heat dissipation fins 12 are fixedly connected to one side of the heat-conducting plate 11 and have a large surface area, which can increase the contact area with the surrounding air. After the heat is conducted through the heat-conducting plate 11, it is dissipated by the heat dissipation fins. The heat exchange between the heat sink 12 and the air accelerates the dissipation of heat into the surrounding environment, improving heat dissipation efficiency. A cooling fan 13 is fixedly connected to one side of the heat conduction plate 11. The cooling fan 13 is located on the side of the heat sink 12 and is electrically connected to an external power supply. When the cooling fan 13 is started, the rotation of its own blades drives the surrounding air to flow, so that the hot air around the heat sink 12 can be quickly blown away and carried away, and the cold air can be replenished in time, further enhancing the heat exchange effect between the heat sink 12 and the air, accelerating the entire heat dissipation process, and more effectively reducing the temperature of the LED light.
[0026] The horizontal support rod 2 has two fixed ends with insertion strips 14, which are inserted into the insertion slots of the horizontal fixing box 5. The movable clamp 6 is clamped on one side of the outer surface of the insertion strip 14. The vertical support rod 3 has two fixed ends with insertion strips 14, which are inserted into the insertion slots of the vertical fixing box 5. The movable clamp 6 is clamped on one side of the outer surface of the insertion strip 14. The movable clamp 6 is engaged with the screw 7 through the through hole on its outer surface. Under the rotation of the screw 7, the knob 10 is driven to push the movable clamp 6 to slide along the sliding groove inside the fixing box 5. One side of the movable clamp 6 can clamp the outer surface of the insertion strips 14 at the ends of the horizontal support rod 2 and the vertical support rod 3. The clamping force of the movable clamp 6 enhances the tightness of the connection between the insertion strip 14 and the fixing box 5.
[0027] The working principle of this utility model is as follows: During the assembly of the LED lamp holder, multiple sets of connecting components 1 and multiple sets of horizontal support rods 2 and vertical support rods 3 are prepared. The insertion strips 14 at both ends of the horizontal support rod 2 are inserted into the insertion slots of the horizontal fixing box 5, and the insertion strips 14 at both ends of the vertical support rod 3 are inserted into the insertion slots of the vertical fixing box 5. At this time, the movable clamp 6 is in the initial position under the action of the spring 9 and the telescopic rod 8. By rotating the knob 10, the knob 10 drives the screw 7 to rotate. When the screw 7 rotates, it engages with the threaded hole on the inner wall of the slide groove inside the fixing box 5, so that the screw 7 enters the threaded hole. At the same time, the knob 10 moves with the screw 7, and the knob 10 pushes the movable clamp 6 to slide along the slide groove toward the insertion strip 14. The movable clamp 6 tightly clamps the insertion strip 14 under the push of the knob 10, so that the horizontal support rod 2 and the vertical support rod 3 are firmly connected, thus building a complete LED light frame structure. When the LED light is installed, it is attached to the heat conduction plate 11. The heat generated by the LED light when it is working is transferred to the heat dissipation fins 12 through the heat conduction plate 11. The heat dissipation fins 12 use their large surface area to exchange heat with the surrounding air. After the cooling fan 13 is started, the air flow is accelerated, so that the hot air around the heat dissipation fins 12 is quickly blown away, and the cold air is continuously replenished, continuously removing heat and maintaining the LED light within a suitable working temperature range, ensuring its stable and efficient operation, and achieving good lighting effects and reliable operation of the dome theater.
