Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and more specifically, to a stage light with a centralized aperture heat dissipation system. Background Technology

[0002] During the operation of stage lights, the light source emits a high-temperature beam of light. Optical components exposed to the high-temperature beam are easily damaged by heat. Therefore, in order to avoid damage caused by the high temperature of optical components, heat dissipation treatment is required for the optical components through which the beam passes. However, in the existing technology, some optical components that do not need to be exposed to the beam of light for a long time are not equipped with dedicated heat dissipation devices in order to save space or cost. For example, aperture components. Therefore, the heat dissipation efficiency of existing aperture components is lower than that of other optical components, and even more so, they share heat dissipation devices with other optical components.

[0003] However, with technological advancements, the working time of aperture components has increased, and the time they are exposed to light has lengthened. Existing heat dissipation technologies are no longer sufficient to meet the heat dissipation needs of aperture components. Utility Model Content

[0004] To overcome at least one of the defects described in the prior art, this utility model provides a stage light with centralized aperture heat dissipation, which equips the aperture component with an independent heat dissipation device to cope with the heat accumulated as the aperture component's working time increases, and avoids thermal deformation damage caused by untimely heat dissipation of the aperture component.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a stage light with a centralized aperture heat dissipation, including a support arm, a lamp head, and a base housing. The lamp head is pivotally connected to the support arm, and the support arm is rotatably disposed above the base housing. The lamp head includes a light source that emits a light beam. An aperture assembly and a light-emitting lens assembly are sequentially arranged along the emission direction of the light beam. The lamp head also includes a mounting base fixedly connected to the lamp head for placing the aperture assembly. The lamp head is characterized by further including an aperture cover that covers the aperture assembly and is fixed to the mounting base. The aperture cover has a light-transmitting hole corresponding to the aperture assembly. The lamp head also includes a fan that blows cold air between the mounting base and the aperture cover or draws out hot air between the mounting base and the aperture cover.

[0006] When the light source emits a high-temperature beam of light and projects it onto the aperture assembly, the fan blows out cool air or draws out hot air to remove the heat from the aperture assembly. At the same time, by setting up an aperture cover, the airflow can be concentrated and blown onto the aperture assembly, providing targeted and centralized cooling for the aperture assembly. This improves the heat dissipation efficiency of the aperture assembly and avoids situations such as the aperture assembly deforming due to prolonged exposure to heat.

[0007] Furthermore, the system includes two fans for blowing cool air between the mounting base and the aperture cover. Utilizing two fans to blow cool air increases the airflow, thereby accelerating the efficiency of heat removal.

[0008] Furthermore, the mounting base plate is provided with a mounting hole corresponding to the fan, through which the fan can partially pass. The fan can move and rise through the mounting hole, thereby adjusting the protrusion height of the fan relative to the mounting base plate, adapting to the internal structural space of different stage lights, and providing greater flexibility.

[0009] Furthermore, it also includes an air guide shroud for connecting the air outlet of the fan to the air inlet of the aperture cover. This guides most of the airflow to the aperture assembly, preventing airflow loss and ensuring heat dissipation efficiency.

[0010] Furthermore, it also includes a drive motor for scaling the aperture assembly and a transmission assembly, the transmission assembly being located outside the aperture cover and covered by the air guide cover. The aperture assembly covered by the aperture cover emits extremely high temperatures, causing the temperature of the portion covered by the aperture cover to also increase, thus preventing it from affecting the transmission assembly.

[0011] Furthermore, the drive shaft of the drive motor is connected to a flange, and the air guide shroud has a through hole corresponding to the flange. Since the flange connected to the drive shaft is relatively high, passing the flange through the through hole reduces the overall height of the air guide shroud relative to the mounting base, thereby reducing the amount of internal space occupied by the stage light.

[0012] Furthermore, the air guide shroud is a bent component, with a guide angle at its top near the fan. The airflow from the fan, after passing through the guide angle, reduces wind resistance and improves airflow smoothness.

[0013] Furthermore, the mounting substrate has a boss on the side near the light source, and the aperture assembly is fixed to the boss. This allows for vertical adjustment based on the focal position of the beam emitted by the light source, increasing installation flexibility.

[0014] Furthermore, a guide plate is fixed to the edge of the protrusion near the fan to direct airflow between the mounting base and the aperture cover. This prevents the airflow from the fan from being blocked by the protrusion and unable to reach the aperture assembly, thus avoiding reduced heat dissipation efficiency.

[0015] Furthermore, the system comprises two fans: one fan blows cool air between the mounting substrate and the aperture cover, and the other fan draws hot air out from between the mounting substrate and the aperture cover. The combination of one fan blowing air and the other drawing air creates a gas circulation loop, thereby accelerating the gas flow and improving heat dissipation efficiency.

[0016] Furthermore, the aperture assembly includes an aperture blade turntable, with a protrusion fixed to the outer periphery of the aperture blade turntable. The mounting substrate has a stop post surrounding the aperture blade turntable, and the protrusion and the stop post are positioned by collision. The positioning structure is simple and precise.

Detailed Implementation

[0022] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0023] like Figure 1This utility model provides a stage light with a centralized aperture heat dissipation system, including a support arm 800, a lamp head, and a base housing 900. The lamp head is pivotally connected to the support arm 800, and the support arm 800 is rotatably disposed above the base housing 900. The lamp head includes a light source 100 that emits a light beam. An aperture assembly 300 and a light-emitting lens assembly 700 are sequentially arranged along the emission direction of the light beam. The lamp head also includes a mounting base 200 fixedly connected to the lamp head for placing the aperture assembly 300. The lamp head is characterized by further including an aperture cover 400 that covers the aperture assembly 300 and is fixed to the mounting base 200. The aperture cover 400 has a light-transmitting hole 410 corresponding to the aperture assembly 300. The lamp head also includes a fan 500 that blows cold air into the space between the mounting base 200 and the aperture cover 400 or draws out hot air from the space between the mounting base 200 and the aperture cover 400.

[0024] When the light source 100 emits a high-temperature beam and projects it onto the aperture assembly 300, the fan 500 blows out cold air or draws out hot air to remove the heat from the aperture assembly 300. At the same time, by setting the aperture cover 400, the airflow can be concentrated and blown onto the aperture assembly 300, providing targeted and centralized cooling for the aperture assembly 300. This improves the heat dissipation efficiency of the aperture assembly 300 and avoids the aperture assembly 300 from deforming due to prolonged exposure to heat.

[0025] like Figure 3 In a preferred embodiment of this invention, two fans 500 are provided for blowing cool air between the mounting base plate 200 and the aperture cover 400. The use of two fans 500 to blow cool air increases the airflow, thereby accelerating the efficiency of heat removal.

[0026] Preferably, the air outlet directions of the two fans 500 are not the same; one fan 500 has an air outlet direction perpendicular to the light beam, while the other fan 500 has an air outlet direction parallel to the light beam.

[0027] Optionally, the two fans 500 have the same air outlet direction, which is either perpendicular to the light beam or parallel to the light beam.

[0028] like Figure 3 In a preferred embodiment of this utility model, the mounting base plate 200 is provided with a mounting hole 210 corresponding to the fan 500, through which the fan can partially pass. The fan 500 can move and rise through the mounting hole 210, thereby adjusting the protrusion height of the fan 500 relative to the mounting base plate 200, adapting to the internal structural space of different stage lights, and thus providing greater flexibility.

[0029] Preferably, the outer side of the fan 500 is provided with a threaded post 510, which is used to fix the fan 500 to the mounting base plate 200.

[0030] Optionally, a connecting plate is fixed to the top of the fan 500, the edge of the connecting plate protruding beyond the maximum outer edge of the fan 500, and the connecting plate extends outward to have a threaded post 510, which is fixedly connected to the mounting base plate 200.

[0031] like Figure 2 and Figure 3 In a preferred embodiment of this invention, an air guide shroud 600 is further included to connect the air outlet of the fan 500 and the air inlet of the aperture shroud 400. This guide shroud can direct most of the airflow to the aperture assembly 300, preventing airflow loss and ensuring efficient heat dissipation.

[0032] Preferably, the air guide cover 600 is fixedly connected to the edge of the aperture cover 400.

[0033] Preferably, the air guide shroud 600 has a wire passage hole 630 for connecting electrical wires.

[0034] like Figure 3 In a preferred embodiment of this invention, the device further includes a drive motor for scaling the aperture assembly 300 and a transmission assembly. The transmission assembly is located outside the aperture cover 400 and is covered by the air guide cover 600. The aperture assembly 300 covered by the aperture cover 400 emits extremely high temperatures, causing the temperature of the portion covered by the aperture cover 400 to also increase, thus preventing it from affecting the transmission assembly.

[0035] Preferably, the transmission assembly is a linkage drive.

[0036] Optionally, the transmission component is a belt drive.

[0037] like Figure 3 In a preferred embodiment of this utility model, the drive shaft of the drive motor is connected to a flange 310, and the air guide shroud 600 is provided with a through hole 610 corresponding to the flange 310. Since the flange 310 connected to the drive shaft is relatively high, passing the flange 310 through the through hole 610 can reduce the overall height of the air guide shroud 600 relative to the mounting base plate 200, thereby reducing the amount of internal space occupied by the stage light.

[0038] like Figure 3In a preferred embodiment of this utility model, the air guide shroud 600 is a bent component, and its top end near the fan 500 has an air guide angle 620. The airflow from the fan 500, after passing through the air guide angle 620, can reduce wind resistance and improve airflow smoothness.

[0039] Preferably, the air guide angle 620 is between 30 and 60 degrees.

[0040] Optionally, the air guide angle 620 is 45 degrees.

[0041] like Figure 1 and Figure 3 In a preferred embodiment of this invention, the mounting substrate 200 has a boss 220 on the side near the light source 100, and the aperture assembly 300 is fixed to the boss 220. This allows for vertical adjustment based on the focal position of the light beam emitted by the light source 100, increasing installation flexibility.

[0042] like Figure 3 In a preferred embodiment of this invention, the edge of the protrusion 220 near the fan 500 is fixed with a guide plate 221 that directs airflow to the space between the mounting base 200 and the aperture cover 400. This prevents the airflow from the fan 500 from being blocked by the protrusion 220 and thus unable to reach the aperture assembly 300, thereby reducing heat dissipation efficiency.

[0043] Preferably, the boss 220 is a bent part, and the boss 220 and the diversion plate are integrally formed.

[0044] like Figure 3 In a preferred embodiment of this invention, two fans 500 are provided. One fan 500 blows cold air between the mounting substrate 200 and the aperture cover 400, while the other fan 500 draws hot air out of the space between the mounting substrate 200 and the aperture cover 400. The combination of one fan blowing air and the other drawing air creates a gas circulation loop, thereby accelerating the gas flow and improving heat dissipation efficiency.

[0045] like Figure 3 In a preferred embodiment of this invention, the aperture assembly 300 includes an aperture blade turntable 320, with a protrusion 330 fixed to the outer periphery of the aperture blade turntable 320. The mounting base plate 200 has a stop post 340 surrounding the aperture blade turntable 320, and the protrusion 330 and the stop post 340 are positioned by collision. The positioning structure is simple and precise.
