Description

Technical Field

[0001] This disclosure relates to the technical field of spotlights, and in particular to a high-power spotlight. Background Technology

[0002] Spotlights, as a widely used lighting device, are found in various settings, from bustling commercial spaces and quiet office environments to noisy industrial sites. Especially in areas requiring bright illumination, high-powered spotlights have become an indispensable choice. With their powerful lighting capabilities, they provide ample light, enabling people to clearly see their surroundings and objects, thereby greatly improving work efficiency and safety.

[0003] However, while high-powered spotlights provide bright illumination, they also bring a problem that cannot be ignored—heat generation. Due to their high power, these spotlights consume a lot of electrical energy during operation, which is converted into light energy and generates a lot of heat energy. Excessive temperature will accelerate the aging and damage of the internal components of the spotlight, resulting in a decline in its performance and even causing malfunctions, greatly increasing the maintenance cost of the spotlight.

[0004] Existing technology, such as patent CN103196119A, discloses an LED spotlight, which includes a heat sink, a lamp head, a high-power COB light source, a reflector, a lens, a cover, and a power supply. The heat sink includes a heat sink body and a heat-conducting block. The heat sink body includes a shell and heat sink fins. The shell has a cavity and heat dissipation grooves. A slot is provided on the inner wall of the shell. The heat-conducting block is made of red copper and is inserted into the slot by an interference fit. A receiving cavity is provided on the upper surface of the heat-conducting block. The substrate is pressed into the receiving cavity by an interference fit. A bracket is fixed to the heat-conducting block by a lug on the bracket. The reflector has a flange located above a step. The lens is placed on the reflector. The cover is installed on the upper end of the heat sink and contacts the lens. After the cover is installed, the bracket presses the substrate, causing deformation of the substrate and the heat-conducting block. The structure of the above spotlight can improve heat dissipation efficiency and improve the reliability of LED light source fixation.

[0005] However, the aforementioned spotlights use an aluminum substrate as a heat conduction medium, transferring the heat generated inside to a heat-conducting block, and then from the heat-conducting block to a heat sink. The aluminum substrate has limited thermal conductivity and cannot quickly and effectively dissipate the heat generated by the high-power COB light source, causing heat to accumulate inside the spotlight and the temperature to rise continuously. This accelerates the aging and damage of the internal components of the spotlight, thereby reducing its performance and potentially causing malfunctions, thus significantly increasing the maintenance cost of the spotlight. Furthermore, the aforementioned spotlights have a complex structure and are difficult to assemble. Utility Model Content

[0008] A high-power spotlight includes a light source assembly, an aluminum alloy lamp tube, an aluminum alloy heat sink, and a copper heat-conducting component;

[0009] The first end of the aluminum alloy lamp tube has a light outlet, and the second end of the aluminum alloy lamp tube is fixedly connected to the aluminum alloy heat sink to form a mounting groove, and the light source assembly is installed in the mounting groove.

The copper heat-conducting component passes through the mounting hole and is threadedly connected to the aluminum alloy heat sink.

[0015] In one embodiment, the copper heat-conducting element is provided with a handle.

[0016] In one embodiment, the light source assembly includes a reflector and a light source element. The reflector is installed in the mounting groove, and the light-emitting end of the light source assembly is located at the light source element. The first end of the reflector is located at the light outlet and is detachably connected to the first end of the aluminum alloy lamp tube. The second end of the reflector is fixedly connected to the fixed end of the light source element. The light-emitting end of the light source element is located inside the reflector and faces the light outlet. The fixed end of the light source element is opposite to the first end of the copper heat-conducting component, and the thermal grease is filled between the fixed end of the light source element and the first end of the copper heat-conducting component.

[0017] In one embodiment, the reflector is detachably connected to the aluminum alloy lamp tube.

[0018] In one embodiment, the light source assembly further includes a floodlight lens, which is disposed at the light outlet and fixedly connected to the first end of the reflector.

[0019] In one embodiment, the cross-sectional area of ​​the first end of the reflector is greater than the cross-sectional area of ​​the second end of the reflector.

[0020] In one embodiment, the inner peripheral wall of the first end of the aluminum alloy lamp tube is formed with a third threaded connection surface, and the outer peripheral wall of the first end of the reflector is formed with a fourth threaded connection surface that is adapted to the third threaded connection surface. The reflector is disposed in the mounting groove and is threadedly connected to the aluminum alloy lamp tube.

[0021] In one embodiment, a fastener is provided on both sides of the aluminum alloy lamp tube.

[0022] In one embodiment, the aluminum alloy heat sink also forms a plurality of heat dissipation holes, each of which is connected to the mounting slot.

[0023] Compared with the prior art, this disclosure includes, but is not limited to, the following advantages:

[0024] 1. The aforementioned high-power spotlight has a light outlet at the first end of the aluminum alloy lamp tube, and the second end of the aluminum alloy lamp tube is fixedly connected to the aluminum alloy heat sink to form a mounting groove. The light source assembly is installed in the mounting groove, and the aluminum alloy heat sink has mounting holes that communicate with the mounting groove. This allows the high-power spotlight to reduce its overall weight through the aluminum alloy lamp tube and aluminum alloy heat sink, while also ensuring that the high-power spotlight has good structural strength.

[0025] 2. Since the copper heat-conducting component passes through the mounting hole and connects to the aluminum alloy heat sink, part of the copper heat-conducting component is located in the mounting groove and abuts against the light-emitting end of the light source assembly. The copper heat-conducting component is used to transfer the heat generated by the light-emitting end of the light source assembly to the aluminum alloy heat sink. Compared with the method of using an aluminum substrate to transfer the heat generated by the high-power COB light source to the heat sink in the LED spotlights mentioned above, the thermal conductivity of copper is higher than that of aluminum. This allows the high-power spotlight of this disclosure to transfer the heat generated by the light-emitting end of the light source assembly to the aluminum alloy heat sink more quickly through the copper heat-conducting component, thereby greatly improving the heat dissipation efficiency of the high-power spotlight and avoiding the accelerated aging and damage of its internal components due to excessive internal temperature, thus greatly reducing the maintenance cost of the high-power spotlight.

[0037] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0038] like Figures 1 to 6 As shown, a high-power spotlight 10 in one embodiment includes a light source assembly 100, an aluminum alloy lamp barrel 200, an aluminum alloy heat sink 300, and a copper heat-conducting component 400. The first end of the aluminum alloy lamp barrel 200 has a light outlet 210, and the second end of the aluminum alloy lamp barrel 200 is fixedly connected to the aluminum alloy heat sink 300 to form a mounting groove 500. The light source assembly 100 is installed in the mounting groove 500, and the aluminum alloy heat sink 300 has a mounting hole 310 that communicates with the mounting groove 500. This allows the high-power spotlight 10 to reduce its overall weight through the aluminum alloy lamp barrel 200 and the aluminum alloy heat sink 300, while also ensuring that the high-power spotlight 10 has good structural strength.

[0039] like Figures 1 to 6As shown, further, a copper heat-conducting component 400 passes through the mounting hole 310 and is connected to the aluminum alloy heat sink 300. A portion of the copper heat-conducting component 400 is located within the mounting groove 500 and abuts against the light-emitting end of the light source assembly 100. The copper heat-conducting component 400 is used to transfer the heat generated by the light-emitting end of the light source assembly 100 to the aluminum alloy heat sink 300. Compared with the method in the aforementioned related technologies where an aluminum substrate is used to transfer the heat generated by a high-power COB light source to the heat sink, the thermal conductivity of copper is higher than that of aluminum. This makes the high-power light source of this disclosure... The lamp 10 can more quickly transfer the heat generated at the light-emitting end of the light source assembly 100 to the aluminum alloy heat sink 300 through the copper heat-conducting component 400, thereby greatly improving the heat dissipation efficiency of the high-power spotlight 10 and avoiding accelerated aging and damage of its internal components due to excessive internal temperature, thus greatly reducing the maintenance cost of the high-power spotlight 10. At the same time, compared with the LED spotlights in the above-mentioned related technologies, the high-power spotlight 10 of this disclosure has a simpler and more compact overall structure, thereby greatly reducing the assembly difficulty of the high-power spotlight 10 of this disclosure.

[0040] In this embodiment, when the high-power spotlight 10 is in operation, the light-emitting end of the light source assembly 100 generates a large amount of heat. The copper heat-conducting component 400 can quickly transfer the heat generated by the light-emitting end of the light source assembly 100 to the aluminum alloy heat sink 300. The heat generated by the high-power spotlight 10 is then transferred to the external environment through the aluminum alloy heat sink 300. At the same time, the aluminum alloy lamp tube 200 can also transfer some of the heat generated by the high-power spotlight 10 to the external environment, which greatly improves the heat dissipation efficiency of the high-power spotlight 10.

[0041] The aforementioned high-power spotlight 10 has a light outlet 210 formed at the first end of the aluminum alloy lamp tube 200, and the second end of the aluminum alloy lamp tube 200 is fixedly connected to the aluminum alloy heat sink 300 to form a mounting groove 500. The light source assembly 100 is installed in the mounting groove 500, and the aluminum alloy heat sink 300 has a mounting hole 310 that communicates with the mounting groove 500. This allows the high-power spotlight 10 to reduce its overall weight through the aluminum alloy lamp tube 200 and the aluminum alloy heat sink 300, while also ensuring that the high-power spotlight 10 has good structural strength.

[0042] Furthermore, since the copper heat-conducting component 400 passes through the mounting hole 310 and is detachably connected to the aluminum alloy heat sink 300, and part of the copper heat-conducting component 400 is located in the mounting groove 500 and abuts against the light-emitting end of the light source assembly 100, the copper heat-conducting component 400 is used to transfer the heat generated by the light-emitting end of the light source assembly 100 to the aluminum alloy heat sink 300. Compared with the method of using an aluminum substrate to transfer the heat generated by the high-power COB light source to the heat sink in the LED spotlights mentioned above, the thermal conductivity of copper is higher than that of aluminum. This allows the high-power spotlight 10 of this disclosure to transfer the heat generated by the light-emitting end of the light source assembly 100 to the aluminum alloy heat sink 300 more quickly through the copper heat-conducting component 400, thereby greatly improving the heat dissipation efficiency of the high-power spotlight 10 and avoiding the accelerated aging and damage of its internal components due to excessive internal temperature, thus greatly reducing the maintenance cost of the high-power spotlight 10.

[0043] Compared with the LED spotlights in the aforementioned related technologies, the high-power spotlight 10 of this disclosure has a simpler and more compact overall structure, which greatly reduces the assembly difficulty of the high-power spotlight 10 of this disclosure.

[0044] like Figure 2 As shown, in one embodiment, a thermally conductive silicone grease block (not shown) is filled between the copper heat-conducting component 400 and the light-emitting end of the light source assembly 100 to increase the heat-conducting area between the copper heat-conducting component 400 and the light-emitting end of the light source assembly 100. This avoids the obstruction of heat transfer due to gaps in the contact surfaces between the copper heat-conducting component 400 and the light-emitting end of the light source assembly 100, thereby greatly improving the heat dissipation efficiency of the high-power spotlight 10, effectively reducing the aging and damage rate of the internal components of the high-power spotlight 10, and thus greatly reducing the maintenance cost of the high-power spotlight 10.

[0045] like Figures 1 to 3 As shown, in one embodiment, the aluminum alloy lamp tube 200 and the aluminum alloy heat sink 300 are integrally formed to improve the structural compactness of the high-power spotlight 10.

[0046] like Figure 3 and Figure 5 As shown, in one embodiment, the copper heat-conducting component 400 is detachably connected to the aluminum alloy heat sink 300 to reduce the assembly and maintenance difficulty of the high-power spotlight 10.

[0047] like Figure 3 and Figure 5As shown, in one embodiment, the outer peripheral wall of the copper heat-conducting component 400 is formed with a first threaded connection surface 410, and the inner peripheral wall of the mounting hole 310 is formed with a second threaded connection surface 320 that is adapted to the first threaded connection surface 410. The copper heat-conducting component 400 passes through the mounting hole 310 and is threadedly connected to the aluminum alloy heat sink 300, so as to facilitate the installation and disassembly of the copper heat-conducting component 400. This not only reduces the assembly difficulty of the high-power spotlight 10, but also makes it convenient and quick to replace the thermal grease block when the high-power spotlight 10 is used, thereby greatly improving the ease of use of the high-power spotlight 10.

[0048] As shown in Figure 5, in one embodiment, the copper heat-conducting component 400 is provided with a handle 420 to facilitate the user to rotate the copper heat-conducting component 400 relative to the aluminum alloy heat sink 300, making it more convenient and faster for the user to replace the thermal grease block of the high-power spotlight 10, and further improving the ease of use of the high-power spotlight 10.

[0049] like Figures 1 to 3 As shown, in one embodiment, the light source assembly 100 includes a reflector 110 and a light source element 120. The reflector 110 is installed in the mounting groove 500. The light-emitting end of the light source assembly 100 is located at the light source element 120. The first end of the reflector 110 is located at the light outlet 210 and is detachably connected to the first end of the aluminum alloy lamp tube 200. The second end of the reflector 110 is fixedly connected to the fixed end of the light source element 120. The light-emitting end of the light source element 120 is located inside the reflector 110 and faces the light outlet 210, so that the light-emitting end of the light source element 120 can illuminate the target area through the light outlet 210. At the same time, the reflector 110 can also reflect light that would otherwise be unable to pass through the light outlet 210. The light illuminating the target area improves the light utilization rate of the high-power spotlight 10, thereby greatly enhancing the lighting effect of the high-power spotlight 10. The fixed end of the light source component 120 abuts against the first end of the copper heat-conducting component 400, and the thermal grease is filled between the fixed end of the light source component 120 and the first end of the copper heat-conducting component 400 to increase the heat conduction area between the copper heat-conducting component 400 and the light source component 120. This avoids the heat transfer being hindered due to gaps in the contact surface between the copper heat-conducting component 400 and the light source component 120, thus greatly improving the heat dissipation efficiency of the high-power spotlight 10 and effectively reducing the aging and damage rate of the internal components of the high-power spotlight 10, thereby greatly reducing the maintenance cost of the high-power spotlight 10.

[0050] like Figures 2 to 4 As shown, in one embodiment, the reflector 110 is detachably connected to the aluminum alloy lamp tube 200 to further reduce the assembly and maintenance difficulty of the high-power spotlight 10.

[0051] like Figure 2As shown, in one embodiment, the light source assembly 100 further includes a floodlight lens 130, which is disposed at the light outlet 210 and fixedly connected to the first end of the reflector 110, so that the floodlight lens 130 can evenly diffuse the light emitted from the light-emitting end of the light source 120, making the illumination of the high-power spotlight 10 softer and more comfortable, reducing glare and shadows, and also helping to improve the overall lighting quality, making the illuminated objects clearer and more three-dimensional.

[0052] like Figure 2 and Figure 4 As shown, in one embodiment, the cross-sectional area of ​​the first end of the reflector 110 is larger than the cross-sectional area of ​​the second end of the reflector 110, so as to expand the illumination range of the high-power spotlight 10, ensure that more areas receive sufficient light, improve the uniformity of light, reduce shadow areas in the illumination, and thus improve the overall lighting quality of the high-power spotlight 10.

[0053] like Figures 2 to 4 As shown, in one embodiment, the inner peripheral wall of the first end of the aluminum alloy lamp tube 200 is formed with a third threaded connection surface 220, and the outer peripheral wall of the first end of the reflector 110 is formed with a fourth threaded connection surface 111 that is adapted to the third threaded connection surface 220. The reflector 110 is disposed in the mounting groove 500 and threadedly connected to the aluminum alloy lamp tube 200, so as to greatly reduce the difficulty of installing and disassembling the reflector 110, reduce the difficulty of assembling and replacing the reflector 110, and at the same time, it can also make the fixed end of the light source 120 reliably abut against the first end of the copper heat-conducting component 400, so as to avoid the phenomenon that the fixed end of the light source 120 separates from the first end of the copper heat-conducting component 400 due to the influence of external factors on the high-power spotlight 10, and ensure that the high-power spotlight 10 can maintain stable normal operation, greatly improving the stability of the high-power spotlight 10.

[0054] like Figures 1 to 3 As shown, in one embodiment, a buckle 230 is provided on both sides of the aluminum alloy lamp tube 200 so that the high-power spotlight 10 can be snapped and fixed to the building body by the buckle 230.

[0055] like Figures 2 to 3As shown, in one embodiment, the aluminum alloy heat sink 300 also forms a plurality of heat dissipation holes 330, each of which is connected to the mounting groove 500 to increase the contact area between the aluminum alloy heat sink 300 and the air, thereby improving the heat dissipation capacity of the aluminum alloy heat sink 300. At the same time, it promotes the airflow between the mounting groove 500 and the external environment, forming convection heat dissipation. When the air flows through the heat dissipation holes 330, it will carry away the heat on the aluminum alloy heat sink 300, thereby reducing the temperature on the aluminum alloy heat sink 300. This further improves the heat dissipation efficiency of the high-power spotlight 10, effectively reduces the aging and damage rate of the internal components of the high-power spotlight 10, and thus greatly reduces the maintenance cost of the high-power spotlight 10.

[0056] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
