Description

Technical Field

[0001] The utility model relates to the field of stage lamps, in particular to a high-efficiency heat dissipation stage lamp. Background Art

[0002] A stage light typically includes a base and a rotatable lamp head assembly. During the design process, consideration must be given to both the heat dissipation of the light-emitting unit within the lamp head assembly and the heat dissipation of the base. In the prior art, heat dissipation is achieved by using a cooling fan to blow air directly onto the heat-generating area. However, stage lights typically also require a certain degree of waterproofing, so cooling fans typically cannot blow directly onto the heat-generating area. Instead, they must be sealed, transfer heat to the radiator via heat transfer, and then dissipate heat using a cooling fan. Therefore, achieving efficient heat dissipation while ensuring waterproofing is a challenge in this field. Utility Model Content

[0033] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; it may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model in specific circumstances.

[0034] For example, please refer to Figure 1-8 As shown:

[0035] A high-efficiency heat dissipation stage lamp includes a base 300; a lamp head assembly 100 is rotatably connected to opposite sides of the base 300 via arms 200; a heat sink 110 is sealedly connected to the bottom of the lamp head assembly 100; a first heat dissipation fan 140 is connected to the bottom of the heat sink 110; the heat sink 110 includes a connecting plate 111 and a plurality of first heat dissipation fins 120 arranged at intervals on the bottom of the connecting plate 111; the top of the heat sink 110 is a flat connecting plate 111; the term "flat" generally refers to having a relatively flat surface; for example, Figure 2 In the figure, the connecting plate 111 is a plane, the upper plane is the mounting surface, and the lower plane is used to mount the first heat dissipating fin 120. When the mounting surface provides a complete plane, it can ensure better contact with the heat generating part, ensure rapid heat transfer, and facilitate installation.

[0036] A main air duct 130 is formed in the middle of the bottom of the connecting plate 111; a plurality of first heat dissipation fins 120 are spaced apart on the sides of the main air duct 130; the first heat dissipation fins 120 are usually arranged on opposite sides of the main air duct 130; a first air duct 123 is formed between two adjacent first heat dissipation fins 120; the first air duct 123 is connected to the main air duct 130; the extension direction of the main air duct 130 is preferably consistent with the length direction of the connecting plate 111, so that the length of the first heat dissipation fins 120 on both sides of the main air duct 130 can be shortened, and the length of the first air duct 123 is also shortened. Figure 5 As shown, the length of the first heat dissipation fin 120 is Figure 5 The left-right dimensions in the middle allow the air blown by the first cooling fan 140 to pass through the first air duct 123 more quickly, thereby improving the cooling effect. At the same time, the connecting structure between the main air duct 130 and the first air duct 123 allows the first air ducts 123 between the first cooling fins 120 to communicate with each other. The air blown by the first cooling fan 140 can cover the entire bottom of the connecting plate 111 as much as possible, reducing the existence of blind spots and effectively improving the uniformity of heat dissipation.

[0037] The base 300 has an enclosed accommodating space formed therein. A top plate 311 is formed on the top of the base 300. A first circuit board 340 is fixedly connected to the inside of the top plate 311 and is located within the accommodating space and spaced apart from the top plate 311. A second cooling fan 360 is fixedly connected to the side of the first circuit board 340. Air from the second cooling fan 360 passes through the first circuit board 340 and is directed in the longitudinal direction of the top plate 311. The bottom of the second cooling fan 360 is suspended in the accommodating space.

[0038] In one embodiment, a plurality of first grooves 112 are provided on the top of the connecting plate 111. The first grooves 112 can be used to install structures such as a lifting motor to provide an accommodation space therefor.

[0039] In one embodiment, a sealing ring installation groove 113 is provided on the circumference of the connecting plate 111. A sealing ring is provided in the sealing ring installation groove 113. The sealing ring installation groove 113 can limit the position of the sealing ring and improve the sealing effect. The heat sink 110 is sealed to the lamp holder assembly 100 via the sealing ring.

[0040] In one embodiment, the heat dissipation fin 120 includes a first heat dissipation portion 121 and a second heat dissipation portion 122; the first heat dissipation portion 121 is arranged near the edge of the connecting plate 111; the second heat dissipation portion 122 is arranged near the main air duct 130; the height of the second heat dissipation portion 122 is less than the height of the first heat dissipation portion 121 to form a fan mounting slot; by lowering the height of the second heat dissipation portion 122 to form an installation space for accommodating the first heat dissipation fan 140, the space of the radiator 110 can be effectively utilized and the occupation of the external space can be reduced. Although lowering the height of the second heat dissipation portion 122 will reduce the contact area between the heat dissipation fin 120 and the air, due to the main air duct 130 The connection structure with the first air duct 123 improves the fluidity of the airflow, and the heat exchange rate is higher, which can still ensure that the radiator 110 has a good heat dissipation effect. At the same time, because the second heat dissipation portion 122 is closest to the first heat dissipation fan 140, the wind blown by the first heat dissipation fan 140 has the highest wind speed at the second heat dissipation portion 122, and the wind speed will decrease further to the first heat dissipation portion 121. The higher the wind speed, the better the heat dissipation effect. Correspondingly, reducing the height of the second heat dissipation portion 122 can also ensure that the heat dissipation effects of the first heat dissipation portion 121 and the second heat dissipation portion 122 are closer, thereby achieving consistent heat dissipation at all locations of the first heat dissipation fins 120.

[0041] In one embodiment, a first cooling fan 140 is fixedly connected to the fan mounting slot; a plurality of the first cooling fans 140 are provided and fixedly connected to the fan mounting slot via a fan bracket 210; the first cooling fan 140 is arranged opposite the main air duct 130; three first cooling fans 140 are provided and arranged sequentially along the length of the main air duct 130, covering the main air duct 130 as much as possible to ensure efficient heat dissipation; a fan protection cover 150 is provided outside the first cooling fan 140 and fixedly connected to the first cooling fins 120 to prevent debris from entering the first cooling fan 140 and improve safety;

[0042] In one embodiment, the angle between the first heat dissipation portion 121 and the second heat dissipation portion 122 is α, wherein 120°≤α≤180°. In one embodiment, α=150°. A large angle helps guide the wind, and the wind blown by the first heat dissipation fan 140 is more easily guided to flow into the first air duct 123. In one embodiment, the second heat dissipation portion 122 is tilted toward the center of the main air duct 130. Figure 4 As shown, the second heat dissipation parts 122 are all inclined toward the center; the inclined setting of the second heat dissipation parts 122 can not only increase the available length, thereby increasing the contact area with the air, but also can be used to guide the wind; in one embodiment, the first heat dissipation fan 140 is provided, which is arranged in the middle of the main air duct 130, and can make full use of the guide structure formed by the second heat dissipation parts 122 inclined toward the center of the main air duct 130, so as to maximize the air outlet utilization of the first heat dissipation fan 140.

[0044] The first circuit board 340 is spaced apart from the mounting plate 320 so that the air blown out by the second cooling fan 360 can pass through the upper and lower end surfaces of the first circuit board 340, thereby increasing the contact area with the first circuit board 340 and taking away heat more quickly; the second cooling fan 360 is arranged on one side of the first circuit board 340; the air outlet direction of the second cooling fan 360 passes through the first circuit board 340 and is toward the length direction of the top plate 311; the bottom of the second cooling fan 360 is spaced apart from the bottom plate 301; the air outlet direction of the second cooling fan 360 is along the length direction of the top plate 311, which can reduce the obstruction of the internal components to the wind, so that the air outlet of the second cooling fan 360 can travel a longer distance and blow along the length direction, which has relatively better wind fluidity; the first circuit board 340 is directly facing the air outlet of the second cooling fan 360, and the first circuit board 340 is arranged parallel to the top plate 311, with a small wind blocking area, which is conducive to air outlet;

[0045] The second cooling fan 360 is mounted on the mounting plate 320; the bottom of the second cooling fan 360 is suspended in the accommodating space. It can be understood that the bottom of the second cooling fan 360 is spaced apart from the bottom plate 301, and the wind blown by the second cooling fan 360 is more likely to form a Figure 8 The circulating air in the direction indicated by the black line in the middle makes the internal air flow better and can ensure a faster flow speed, which is beneficial to heat transfer. The heat can be better transferred to the outside through the base cover 310 and the bottom plate 301;

[0046] In one embodiment, a second circuit board 350 is connected to the bottom of the first circuit board 340 via connecting posts 341. Four connecting posts 341 are provided, one at each corner of the first circuit board 340. This design enables a double-layer circuit board arrangement, and the double-layer circuit board structure, combined with the second cooling fan 360, provides a better heat dissipation effect. It should be noted that the bottom of the second circuit board 350 is also spaced apart from the bottom plate 301, so that both the upper and lower end surfaces of the second circuit board 350 can be used for heat dissipation. The first circuit board 340 can be spaced apart from the mounting plate 320 by using shorter connecting posts 341 or by using a sleeve. For example, a sleeve having an internal thread is provided at the bottom of the mounting plate 320, and the first circuit board 340 is fixed to the mounting plate 320 by screws connected to the internal thread of the sleeve.
