Description

Technical Field

[0001] This application relates to the technical field of lighting accessories, and in particular to an integrated cutting system for stage lights. Background Technology

[0002] Stage lights typically have a cutting system inside, which is used to partially block and trim the beam of light emitted by the light source, thereby projecting triangular, quadrilateral, polygonal or other irregular geometric shapes of light effects onto the stage surface.

[0003] In related technologies, the cutting system consists of a cutting assembly and a cutting drive assembly. The cutting assembly has a shutter installed in the center of the cutting disc, and several cutting blades are arranged at the bottom of the cutting disc, each blade correspondingly embedded in a strip-shaped track groove. The cutting drive assembly is installed on top of the cutting disc, and each cutting blade has two drive motors. These two drive motors, along with connecting rods, are connected to the two ends of the corresponding cutting blades. During operation, the two drive motors, in conjunction with the connecting rods, drive the cutting blades to move back and forth along the corresponding strip-shaped track grooves. By controlling the entry step distance and deflection angle of different cutting blades, the light beam can be cut into various different shapes and lighting effects.

[0004] Regarding the aforementioned technologies, existing stage lighting cutting systems typically have an open structure and are directly integrated into the optical path inside the stage light. On one hand, they are exposed to direct sunlight during operation, resulting in a continuous high-temperature environment. On the other hand, the drive motor itself generates heat during operation, which can easily lead to overheating and burnout of the cutting blades, as well as overheating and damage to the drive motor. Therefore, there is room for improvement. Summary of the Invention

[0005] In order to better dissipate heat from the stage lighting cutting system and reduce the risk of overheating damage to the cutting blades and drive motor, this application provides an integrated cutting system for stage lighting.

[0006] This application provides an integrated cutting system for stage lights, which adopts the following technical solution: An integrated cutting system for stage lights, comprising a cutting system body and a heat dissipation structure; The cutting system body includes a cutting component and a cutting drive component. The cutting component includes a cutting disk, and an optical shutter is installed in the middle of the cutting disk. The cutting drive component includes a drive support plate. The cutting disk is installed on the bottom side of the drive support plate. The heat dissipation structure includes a heat dissipation plate and a heat dissipation box. The heat dissipation box is installed on the bottom side of the heat dissipation plate and forms an installation cavity with the heat dissipation plate. The heat dissipation plate and the heat dissipation box are respectively provided with a first light-transmitting hole and a second light-transmitting hole. The cutting system body is installed in the installation cavity. The first light-transmitting hole and the second light-transmitting hole are both arranged opposite to the light shutter of the cutting disk. The heat dissipation plate is provided with two first heat dissipation vents. Each of the first heat dissipation vents is equipped with a first cooling fan. The two first cooling fans are used to cooperate in dissipating heat from the cutting system body located in the installation cavity.

[0007] By adopting the above technical solution, when the lamp is working, the light beam emitted by the light source passes through the first light-transmitting hole, the light shutter and the second light-transmitting hole in sequence through the mounting cavity. The cutting component and the cutting drive component work together to cut and shape the light beam. By installing the cutting system body in the mounting cavity formed by the heat sink plate and the heat sink box, on the one hand, the two first cooling fans on the heat sink plate work together with the air in the mounting cavity to exchange heat and cool down, which effectively reduces the situation of the cutting component cutting blade overheating and burning and the driving motor of the cutting drive component overheating and failing. On the other hand, the heat sink plate and the heat sink box can be used to prevent external dust and impurities from adhering to the surface of the cutting blade of the cutting component.

[0008] Preferably, the cutting assembly further includes four cutting blades disposed at the bottom of the cutting disk; the four cutting blades are arranged around the optical shutter; The drive support plate has two second heat dissipation vents on its bottom side, and the second heat dissipation vents are equipped with second cooling fans, which are used to dissipate heat from the cutting blade.

[0009] By adopting the above technical solution, and using two second cooling fans to dissipate heat from the cutting blade, the heat dissipation effect of the cutting blade area of ​​the cutting disc is improved.

[0010] Preferably, both of the first cooling fans are first row fans, which are used to exhaust air to the outside of the mounting cavity; Both of the second cooling fans are second-row fans, with the air inlets of the second-row fans facing the four cutting plates; and the air outlets of the second-row fans facing the second heat dissipation vents.

[0011] By adopting the above technical solution, when the stage light is working, the two first-row fans work in sync to exhaust air out of the mounting cavity, forming a continuous heat exhaust channel inside the mounting cavity. This helps to remove the heat generated by the light source and drive motor, thereby cooling the cutting blade and drive motor. By setting up two second-row fans, the heat from the cutting blade area is concentrated and drawn away to the upper part of the mounting cavity, so that the two first-row fans can better exhaust the heat, which helps to concentrate and remove the heat from the surface of the cutting blade, improving the heat dissipation effect of the cutting blade.

[0012] Preferably, the two first cooling fans are a first blowing fan and a first exhaust fan, respectively; the first blowing fan is used to blow air into the mounting cavity, and the first exhaust fan is used to exhaust air out of the mounting cavity; Both of the second cooling fans are second-row fans, with the air inlets of the second-row fans facing the four cutting plates; and the air outlets of the second-row fans facing the second heat dissipation vents.

[0013] By adopting the above technical solution, the first blower blows cold air into the mounting cavity, while the first row of fans simultaneously exhausts air out of the mounting cavity, forming a directional airflow channel within the mounting cavity. This helps to better cover the internal area of ​​the mounting cavity, thus facilitating the directional exhaust of heat from the mounting cavity to the outside. With the installation of two second rows of fans, the heat from the cutting area is concentrated and drawn away to the upper part of the mounting cavity, so that the directional airflow channel formed by the first blower and the first row of fans can better carry away the heat.

[0014] Preferably, the air inlets of the two second row fans are staggered.

[0015] By adopting the above technical solution, it is beneficial to enable the two second-row fans to better cover the cutting blade area, so that the second-row fans can better exhaust the heat located in the cutting blade area. At the same time, it can avoid the mutual interference of the suction airflow of the two second-row fans, which would affect the heat exhaust of the cutting blade area.

[0016] Preferably, the two second row fans are respectively arranged opposite to the two first row fans.

[0017] By adopting the above technical solution, the hot air extracted by the two second-row fans can be concentrated and transported to the bottom of the two first-row fans, and directly discharged through the two first-row fans. This helps to shorten the heat transport path inside the mounting cavity, reduce the residence time of heat from the light source and the drive motor in the mounting cavity, and improve the heat dissipation efficiency of the cutting system body.

[0018] Preferably, the second row of fans is staggered from the first air blower.

[0019] By adopting the above technical solution, and by staggering the second row of fans with the first blowing fan, it is beneficial to avoid the airflow from the second row of fans and the first blowing fan from colliding, reduce the turbulence and pressure loss of the airflow in the installation cavity, and allow the heat in the upper part of the installation cavity to be better discharged through the directional airflow channel formed by the first blowing fan and the first row of fans.

[0020] Preferably, the first blower fan outlet is equipped with an air duct, which extends into the mounting cavity.

[0021] By adopting the above technical solution, the first blower fan is used to guide the outside cold air into the installation cavity through the air duct. This helps to reduce the diffusion loss of cold air at the top of the installation cavity, and further helps the directional airflow channel formed by the first blower fan and the first exhaust fan to better cover the cutting system body, so as to better remove heat.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By installing the cutting system body in the mounting cavity formed by the heat sink and the heat sink box, and with the first exhaust fan at both ends of the heat sink to exhaust air into the mounting cavity, the cutting system body located in the mounting cavity can be cooled by convection, which can effectively reduce the heat on the cutting system body and reduce the possibility of overheating and damage to the cutting blade and drive motor of the cutting system body.

[0023] 2. By setting two second-row fans on the cutting disc, the heat from the cutting disc area can be drawn upwards by the two second-row fans, which helps to improve the heat dissipation efficiency of the cutting disc area.

[0024] 3. The first blower and the first exhaust fan on the heat sink form a directional airflow channel in the mounting cavity. The directional airflow channel helps to better remove the heat from the cutting system body to the outside of the mounting cavity, thereby improving the heat dissipation efficiency of the cutting system body.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses an integrated cutting system for stage lights. Example

[0034] An integrated cutting system for stage lights, as shown in the reference. Figure 1 and Figure 2 It includes a cutting system body and a heat dissipation structure. The cutting system body is used to cut and shape the stage light beam, and the heat dissipation structure is used to dissipate heat from the cutting system body.

[0035] Reference Figure 1 and Figure 2 The cutting system body includes a cutting component 1 and a cutting drive component 2.

[0036] Reference Figure 2 and Figure 3 The cutting assembly 1 includes a cutting disk 11, with a light shutter 12 installed in the center of the cutting disk 11. The cutting assembly 1 also includes four cutting blades 13 disposed at the bottom of the cutting disk 11, evenly surrounding the light shutter 12. Two cutting blades 13 form a group, forming two cutting blade groups, which are arranged vertically. The cutting disk 11 is supported by two limiting plates 14 corresponding to the two cutting blade groups. Each limiting plate 14 has a first light-transmitting hole in its center, opposite to the light shutter 12. The two cutting blade groups are located between and correspond to the two limiting plates 14. Each limiting plate 14 has two strip-shaped track grooves 141 corresponding to the two cutting blades 13 in each group. The center of each cutting blade 13 is embedded in the corresponding strip-shaped track groove 141 via a connecting pin.

[0037] Reference Figure 2 and Figure 3The cutting drive assembly 2 includes a drive support plate 21. A second light-transmitting hole opposite to the light shutter 12 is opened in the middle of the drive support plate 21. The cutting disk 11 is fixed to the bottom side of the drive support plate 21 by bolts. Two drive motors 22 are installed on the drive support plate 21 for each cutting blade 13. The output ends of the two drive motors 22 are respectively connected to the two ends of the corresponding cutting blade 13 through connecting rods 15. The two drive motors 22 corresponding to each cutting blade 13 work together to drive the cutting blade 13 to swing in the sliding arm of the strip track groove 141, so as to adjust the cutting step and deflection angle of the cutting blade 13, and realize the cutting of the beam into various different shapes and light effects.

[0038] Reference Figure 1 and Figure 4 The heat dissipation structure includes a heat sink 3 and a heat sink box 4. The heat sink 3 is located at the top opening of the heat sink box 4 and seals the opening. The heat sink box 4 and the heat sink 3 cooperate to form an installation cavity. Specifically, several ear plates protrude from the outer side of the opening of the heat sink box 4. The ear plates are all bolted to the bottom side of the heat sink 3 to achieve a stable connection between the heat sink box 4 and the heat sink 3. A first light-transmitting hole 30 is opened in the middle of the heat sink 3, and a second light-transmitting hole 40 is opened at the bottom of the heat sink box 4. The first light-transmitting hole 30 and the second light-transmitting hole 40 are arranged opposite to each other.

[0039] Reference Figure 1 and Figure 4 The cutting system body is installed in the mounting cavity formed by the heat sink 3 and the heat sink box 4. The first light-transmitting hole 30 and the second light-transmitting hole 40 are both set opposite to the light shutter 12 of the cutting disk 11 so that the light beam emitted by the light source can pass through the first light-transmitting hole 30, the light shutter 12 and the second light-transmitting hole 40 in sequence.

[0040] Reference Figure 1 and Figure 2 A support ring 300 is coaxially protruding from the bottom of the heat sink 3; the support ring 300 is located on the outer periphery of the first light-transmitting hole 30. A connecting pipe 20 is coaxially connected to the drive support plate 21 corresponding to the support ring 300, and the connecting pipe 20 is coaxially rotatably connected to the inner periphery of the support ring 300 through a bearing 302. An arc-shaped rack 301 is coaxially connected to the outer periphery of the support ring 300; a swing motor 23 is installed on the drive support plate 21 corresponding to the arc-shaped rack 301, and a drive gear is coaxially connected to the output shaft of the swing motor 23, which meshes with the arc-shaped rack 301. This allows the cutting system body to be stably installed on the bottom side of the heat sink 3, and the drive motor 22, in conjunction with the arc-shaped rack 301, can drive the cutting system body to swing around the support ring 300, which is beneficial to enriching the visual effects of stage lighting.

[0041] Reference Figure 1 and Figure 2The heat sink 3 also has two first heat dissipation vents, which are symmetrically distributed about the first light-transmitting hole 30. Each first heat dissipation vent is equipped with a first cooling fan, which is a first row fan 31, specifically an axial flow fan. The air inlet of the first row fan 31 faces the inside of the mounting cavity, and the air outlet of the first row fan 31 faces the first heat dissipation vent.

[0042] During subsequent stage lighting operation, two first exhaust fans 31 are used to exhaust air from the inside of the mounting cavity, so as to remove the heat from the light source acting on the cutting blade 13 and the drive motor 22, as well as the heat generated by the drive motor 22 during operation, effectively reducing the possibility of overheating damage to the cutting blade 13 and the drive motor 22.

[0043] Reference Figure 1 and Figure 5 Two second heat dissipation vents are provided at the drive support plate 21, symmetrically distributed about the second light-transmitting hole. The second heat dissipation vents are staggered from the drive motor 22 and the swing motor 23. A second cooling fan is installed on the bottom side of each second heat dissipation vent; these are all second-row fans 5, specifically vortex fans. The side air inlets of the second-row fans 5 face outwards from the four cutting plates 13, and the air outlets of the second-row fans 5 face the second heat dissipation vents.

[0044] Subsequently, while the heat is dissipated by the two first-row fans 31 on the heat sink 3, the heat in the area of ​​the cutting blade 13 is concentrated and drawn away to the upper cavity of the mounting cavity by the two second-row fans 5. This improves the heat dissipation efficiency of the cutting blade 13 and makes it easier for the first-row fans 31 to dissipate the heat better.

[0045] Reference Figure 1 and Figure 5 The staggered arrangement of the air inlets of the two second-row fans 5 helps to better cover the cutting blade 13 area, thus facilitating the removal of heat from the cutting blade 13 area. At the same time, it reduces the mutual interference of the suction airflow of the two second-row fans 5, which could affect the suction effect of the second-row fans 5.

[0046] Reference Figure 1 and Figure 5 The two second-row fans 5 are respectively positioned opposite the two first-row fans 31, which helps to concentrate the hot air drawn out by the two second-row fans 5 to the bottom of the two first-row fans 31 and directly discharge it through the two first-row fans 31, effectively shortening the transport path of hot air inside the installation cavity and further improving the heat dissipation efficiency of the cutting system body.

[0047] The implementation principle of Embodiment 1 is as follows: When the stage light is working, the two second-row fans 5 on the drive support plate 21 work together to directionally draw the heat acting on the four cutting blade areas to the upper area of ​​the mounting cavity, and the two first-row fans 31 on the heat sink 3 exhaust the heat generated by the light source and drive motor 22 to the outside of the mounting cavity, thereby achieving heat exchange and cooling of the air in the mounting cavity. This effectively reduces the possibility of overheating damage to the cutting blade 13 of the cutting assembly 1 and the drive motor 22 of the cutting drive assembly 2, which is beneficial to improving the service life and stability of the cutting system body. Example

[0048] The difference between Example 2 and Example 1 is that: (Refer to...) Figure 1 and Figure 6 The two first cooling fans are a first blowing fan 32 and a first exhaust fan 31, both of which are axial flow fans. The air inlet of the first blowing fan 32 faces the first heat dissipation port, and the air outlet of the first blowing fan 32 faces into the mounting cavity; the first blowing fan 32 is used to blow air into the mounting cavity. The air inlet of the first exhaust fan 31 faces into the mounting cavity, and the air outlet of the first blowing fan 32 faces the first heat dissipation port. The first exhaust fan 31 is used to exhaust air out of the mounting cavity.

[0049] When the stage lights are in operation, the first blower fan 32 blows air into the mounting cavity, while the first row fan 31 simultaneously exhausts air out of the mounting cavity, thus forming a directional airflow channel within the mounting cavity; the circulating airflow through the directional airflow channel is used to promptly dissipate the heat generated by the operation of the light source and the drive motor 22.

[0050] Reference Figure 1 and Figure 6 The first blower fan 32 has an air duct installed at its outlet, extending into the mounting cavity, and the duct is offset from the cutting system body. Using the duct to direct the airflow from the first blower fan 32 into the mounting cavity reduces diffusion loss of the cold air at the top of the mounting cavity, allowing the cold air to enter the cavity more effectively. This, in turn, ensures that the directional airflow channel formed by the first blower fan 32 and the first exhaust fan 31 better covers the cutting system body, facilitating better heat dissipation.

[0051] Reference Figure 1 and Figure 6 Both second-row fans 5 are staggered from the first blower fan 32. This is to prevent the airflow from directly colliding with the first blower fan 32, which could cause airflow turbulence and air pressure loss. It also allows the heat in the upper part of the mounting cavity to be better discharged through the directional airflow channel formed by the first blower fan 32 and the first row fan 31.

[0052] The implementation principle of Example 2 is as follows: When the stage light is working, the two second-row fans 5 on the drive support plate 21 work together to directionally draw the heat acting on the four heat sink areas to the upper area of ​​the mounting cavity. The first blower fan 32 and the first row fan 31 on the heat sink plate 3 form a directional airflow channel to exhaust the heat generated by the light source and drive motor 22 to the outside of the mounting cavity, thereby achieving heat exchange and cooling of the air inside the mounting cavity.

[0053] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
