Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and more specifically, to a patterned disc heat insulation structure for stage lighting fixtures. Background Technology

[0002] In the field of stage lighting technology, rotating pattern discs are typically positioned close to the light source to ensure image clarity. When the light source provides continuous illumination, the emitted light is concentrated on a localized area of ​​the disc, causing a rapid increase in local temperature. Existing heat dissipation systems, limited by installation space and heat transfer efficiency, struggle to effectively cool the rotating components. Prolonged accumulation of high temperatures can cause irreversible deformation of the disc material, leading to malfunctions such as jamming or even stopping of the rotating gear seat, directly impacting the stability of light output.

[0003] Therefore, to prevent the disc from aging and deforming due to continuous light exposure or heat, our company provides a patterned disc heat insulation structure for stage lighting fixtures. Summary of the Invention

[0004] This invention provides a patterned disc heat insulation structure for stage lighting fixtures, which can block direct light from hitting the disc and prevent heat transfer.

[0005] A patterned disc heat insulation structure for stage lighting includes a rotating patterned disc assembly, which sequentially includes a circular disc, a plurality of adjacent rotating gear seats that are equally spaced and mounted on the outer edge of the disc for accommodating an image, and a pressure plate that is mounted on the middle of the disc and inserted into the plurality of rotating gear seats respectively. The outer edge of the disc is provided with a plurality of through holes that are spaced around the central axis of the disc. The rotating gear seats are adapted to at least some of the through holes. The structure also includes a heat insulation plate mounted above the arc-shaped pressure plate and below the rotating gear seats. The projection of the heat insulation plate avoids the plurality of rotating gear seats and substantially covers the interval between each pair of adjacent rotating gear seats. An air heat insulation layer is formed between the heat insulation plate and the disc.

[0006] As a further improvement of this utility model, the disk includes an annular irradiated area for light to shine on. The annular irradiated area includes through holes and multiple fan-shaped intervals of the same shape. The outer diameter of the heat insulation plate is larger than the outer diameter of the annular area.

[0007] As a further improvement of this utility model, the heat insulation plate is disc-shaped, and includes a mounting part located in the middle and a plurality of outwardly extending and evenly spaced fan-shaped shielding parts, the shielding parts being adapted to the shape of the interval area.

[0008] As a further improvement of this utility model, the heat insulation plate is provided with the same number of arc-shaped notches as the rotating gear seat for preventing the rotating gear seat from being obstructed, and the diameter of the arc-shaped notches is slightly larger than the outer diameter of the rotating gear seat.

[0009] As a further improvement of this utility model, the heat insulation plate includes a mounting part located on its inner edge and a plurality of shielding parts located on its outer edge, which are evenly interspersed with the arc-shaped notch and adapted to the shape of the interval area. The number of shielding parts is equal to the number of interval areas.

[0010] As a further improvement of this utility model, the rotating pattern disk assembly also includes an upper gear ring for driving the rotating gear seat to rotate and a lower gear ring for driving the disk to rotate. The inner teeth of the upper gear ring mesh with the outer teeth of the rotating gear seat, and the heat insulation plate is located in the inner circumference of the upper gear ring.

[0011] As a further improvement of this utility model, the distance L between the disc and the heat insulation plate is 2.3mm≤L≤3.8mm.

[0012] As a further improvement of this utility model, the heat insulation board includes, but is not limited to, cold-rolled steel.

[0013] As a further improvement of this utility model, the disc is also provided with a plurality of fixing posts for installing the heat insulation plate. The fixing posts are located between every two adjacent rotating gear seats and are evenly spaced around the central axis.

[0014] As a further improvement of this utility model, the height of the fixing column is greater than the installation height of the pressure plate.

[0015] As a further improvement of this utility model, the heat insulation plate is mounted on the pressure plate, and a heat insulation sheet for heat insulation is also provided between the heat insulation plate and the pressure plate. Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) The present invention installs a heat insulation plate above the platen. The heat insulation plate blocks the direct irradiation of the light source by physical shielding, so as to avoid the heat accumulation on the surface of the platen due to continuous irradiation. At the same time, a non-contact air heat insulation layer is formed between the heat insulation plate and the platen. The low thermal conductivity of air medium blocks the heat transfer path between the heat insulation plate and the platen, effectively controlling the working temperature of the platen. Therefore, the heat insulation plate can effectively prevent the platen from aging and deformation caused by direct irradiation of light or long-term heating. Attached Figure Description

Detailed Implementation

[0025] Combined with appendix Figure 1 Appendix Figure 3 and attached Figure 6 A heat insulation structure for a patterned disc used in stage lighting includes a rotating patterned disc assembly 10, which sequentially comprises a circular disc 1, a plurality of rotating gear seats 2 mounted on the outer edge of the disc 1 for accommodating an image, and an arc-shaped pressure plate 3 mounted on the inner circumference of the disc 1 and respectively inserted into the plurality of rotating gear seats 2. The disc 1 is a circular flat plate, and the outer edge of the disc 1 is provided with a plurality of through holes arranged at intervals around the central axis 13 of the disc. The rotating gear seats are adapted to at least some of the through holes. One end of the rotating gear seat 2 is a gear, and its interior is provided with a groove for accommodating the image. The rotating gear seat 2 is installed in the through hole 111 of the disc 1 and can rotate relative to the disc 1. The pressure plate 3 is an arc-shaped flat plate, which is fixed to the middle of the disc 1 by fasteners and is coaxial with the disc 1. It does not block the through hole 111 on the disc 1, preventing the pressure plate 3 from blocking light and affecting the light output effect of the rotating patterned disc assembly 10.

[0026] Traditional rotating pattern disk assemblies typically do not have heat insulation plates, and the spacing areas on the disk are directly exposed to the light source; continuous irradiation by the light source causes the disk temperature to rise, and the disk is prone to aging and deformation when exposed to high temperature direct sunlight for a long time.

[0027] This invention adds a heat insulation plate 4 mounted above the arc-shaped pressure plate 3. The projection of the heat insulation plate 4 avoids the space between multiple rotating gear seats 2 and roughly covers the gap 112 between each pair of adjacent rotating gear seats 2. An air insulation layer 8 is formed between the heat insulation plate 4 and the disc 1. By adding the heat insulation plate 4, the problem of aging and deformation of the disc under the illumination of the light source can be effectively solved. The heat insulation plate 4 is mounted between each pair of adjacent rotating gear seats 2. The size of the heat insulation plate 4 can effectively block the gap 112 between each pair of adjacent rotating gear seats 2 and does not interfere with the rotating gear seats 2. If the size of the heat insulation plate is small, its projection cannot completely cover the gap area, causing light to shine on the gap area of ​​the disc through the gap between the rotating gear seat and the heat insulation plate, which cannot effectively prevent the disc from aging and deforming due to illumination or heat. If the size of the heat insulation plate is large, it will interfere with the rotating gear seats or other components, making the rotating pattern disc assembly unable to operate normally.

[0028] The heat insulation plate 4 does not directly contact the disc 1, but there is a certain gap, namely the air heat insulation layer 8. As can be understood by those skilled in the industry, the thermal conductivity of air is reduced, making it difficult to transfer heat through the air. Therefore, after the heat insulation plate 4 is exposed to light and its temperature rises, its heat will not be transferred to the disc 1, effectively preventing the disc 1 from aging and deforming due to high temperature.

[0029] The beneficial effect of this embodiment is that by adding a heat insulation plate 4, light is prevented from directly shining on the disk 1; and an air insulation layer 8 is placed between the heat insulation plate 4 and the disk 1 to prevent the heat insulation plate 4 from being heated by light and transferring the temperature to the disk 1; thus, the aging and deformation of the disk 1 caused by light exposure and continuous high temperature can be effectively avoided.

[0030] As a new implementation method, combined with the appendix Figure 2 and attached Figure 5The disk 1 includes an annular irradiated area 11 for light illumination. The irradiated area 11 includes through holes 111 and multiple identical fan-shaped intervals 112. The outer diameter of the heat insulation plate 4 is larger than the outer diameter of the irradiated area 11. A rotating gear seat 2 for accommodating the image object is mounted on the through holes 111 of the disk 1. The boundary of the interval 112 between every two through holes 111 is an arc-shaped fan-shaped area. When the disk 1 rotates on the main optical axis, i.e., when alternating image objects, the path formed by the light emitted from the light source on the disk 1 is the irradiated area 11. Because the disk 1 is circular, the irradiated area 11 formed by the light on the disk 1 is annular. When light shines on the through holes 111, the rotating pattern disk assembly 10 can create different light emission effects. The outer tooth diameter of the rotating gear seat 2 is larger than the diameter of the through holes 111, therefore the rotating gear seat 2 will block part of the irradiated area 11 outside the through holes 111. The light rays illuminate the interval 112 between every two adjacent rotating gear seats 2. During this time, the disk 1 absorbs heat from the light, leading to aging and deformation. When the rotating gear seats 2 containing the imaging object alternate, the light emitted by the light source directly illuminates the interval 112, causing the interval 112 to have a relatively high temperature and making it more prone to aging and deformation. Therefore, a heat insulation plate 4 is provided on the side of the disk 1 facing the light source. Its main function is to block the light directly illuminating the interval 112 of the disk. Since the outer diameter of the heat insulation plate 4 is larger than the outer diameter of the irradiated area 11, it can effectively block the interval 112, preventing the light emitted from the light source from illuminating the disk 1 and causing it to age and deform. The beneficial effect of this embodiment is that it can completely block the interval 112, preventing the light from directly illuminating the interval 112 of the disk 1, effectively avoiding deformation of the disk 1 due to high-temperature irradiation.

[0031] As a new implementation method, combined with the appendix Figure 2 and attached Figure 6The heat insulation plate 4 is disc-shaped and includes a mounting portion 42 in the center and multiple outwardly extending and evenly spaced fan-shaped shielding portions 43. The shielding portions 43 are adapted to the shape of the interval area 112. The mounting portion 42 of the heat insulation plate 4 is located between the pressure plate 3 and the rotating gear seat 2. The multiple shielding portions 43 are respectively located between the interval area 112 and the rotating gear seat 2, and are embedded in the gap between each two adjacent rotating gear seats 2, and never come into contact with the rotating gear seat 2. The projection of the shielding portion 43 in the direction of the disc 1 can cover the interval area 112, so that the light emitted by the light source cannot directly shine on the interval area 112 of the disc, but can only shine on the heat insulation plate 4 mounted above the interval area 112. The mounting portion 42 enables the heat insulation plate 4 to be mounted above the disc 1 without contacting the disc 1, that is, there is a certain gap between the heat insulation plate 4 and the disc 1, and the heat absorbed by the heat insulation plate 4 cannot be transferred to the disc 1. The beneficial effect of this embodiment is that the shielding part 43 can prevent light from shining on the disk spacer area 112 located below it, and the mounting part 42 allows the heat insulation plate 4 to be mounted above the disk 1, which can effectively prevent the disk 1 from aging and deforming due to light exposure or heat.

[0032] As a new implementation method, combined with the appendix Figure 2 and attached Figure 5 The heat insulation plate 4 has the same number of arc-shaped notches 41 as the rotating gear seat 2 to avoid interference with the rotating gear seat 2. The diameter of the arc-shaped notches 41 is slightly larger than the outer diameter of the rotating gear seat 41. The heat insulation plate 4 is a disc with four arc-shaped notches 41, and the heat insulation plate 4 is mounted on the disc 1. The arc-shaped notches 41 are evenly spaced on the outer edge of the heat insulation plate 4, and the rotating gear seat 2 is located in the arc-shaped notches 41. The outer edge of the rotating gear seat 2 is an external gear, that is, the outer diameter of the rotating gear seat 2 is the diameter of the tip circle of the external gear. When the rotating gear seat 2 is located in the arc-shaped notch 41, the external gear of the rotating gear seat 2 will not interfere with the heat insulation plate 4, that is, the heat insulation plate 4 hinders the rotation of the rotating gear seat 2. The beneficial effect of this embodiment is that the rotating gear seat 2 does not interfere with the heat insulation plate 4, the heat insulation plate 4 avoids the rotating gear seat 2 through the arc-shaped notches 41, and at the same time blocks the gap area 112 between adjacent gear seats.

[0033] As a new implementation method, combined with the appendix Figure 1The rotating pattern disk assembly 10 also includes an upper gear ring 5 for driving the rotating gear seat 2 to rotate and a lower gear ring 6 for driving the disk 1 to rotate. The internal teeth of the upper gear ring 5 mesh with the external teeth of the rotating gear seat 2, and the heat insulation plate 4 is located within the inner circumference of the upper gear ring 5. The upper gear ring 5 has external teeth and internal teeth. Its external teeth mesh with an external drive device to drive the upper gear ring 5 to rotate; its internal teeth mesh with multiple rotating gear seats 2 respectively. When the upper gear ring 5 rotates, it drives multiple rotating gear seats 2 to rotate. The lower gear ring 6 is connected to the disk 1. The external teeth of the lower gear ring 6 mesh with an external drive device, so that the disk 1 drives the rotating gear seat 2 to revolve. The disk 1 is located within the inner circumference of the upper gear ring 5 and the lower gear ring 6. The heat insulation plate 4 is used to shield the disk 1, and the outer diameter of the heat insulation plate 4 is smaller than the outer diameter of the disk 1. When the disk 1 rotates, the heat insulation plate 4 will not interfere with the upper gear ring 5 or the lower gear ring 6. The beneficial effect of this embodiment is that the heat insulation plate 4 and the upper gear ring 5 are coaxially coupled to ensure that the disc 1 drives the rotating gear seat 2 to revolve normally.

[0034] As a new implementation method, combined with the appendix Figure 4 and attached Figure 7 The distance L between the disc 1 and the heat insulation plate 4 is 2.3mm ≤ L ≤ 3.8mm. In this embodiment, the rotating pattern disc assembly 10 is provided with a locator for positioning the image object, which is located above the rotating gear seat 2. When L > 3.8mm, the heat insulation plate 4 will interfere with the locator; that is, when the disc 1 drives the rotating gear disc 2 to revolve, the heat insulation plate 4 is higher than the rotating gear seat 2 and interferes with the locator located above it, hindering the rotation of the disc 1. When L < 2.3mm, the heat insulation plate 4 will contact the pressure plate 3 located between the heat insulation plate 4 and the disc 1, and the heat on the heat insulation plate 4 will be transferred to the disc 1 through the pressure plate 3, resulting in a significant decrease in heat insulation efficiency. The beneficial effect of this embodiment is that the height h of the air insulation layer 8 is 2.3mm ≤ h ≤ 3.8mm, which can effectively block the heat transfer on the heat insulation plate 4 and prevent the heat insulation plate 4 from interfering with the locator and hindering the rotation of the rotating gear disc 2.

[0035] As a new implementation method, combined with the appendix Figure 1 The heat insulation plate 4 includes, but is not limited to, cold-rolled steel. In this embodiment, the heat insulation plate 4 is made of cold-rolled steel. Compared to ceramic materials, cold-rolled steel is more resilient, and it will not break when fasteners lock it onto the disc 1. Compared to plastic, cold-rolled steel has no risk of melting at high temperatures. Under long-term operating conditions below 200°C, the thermal stability of cold-rolled steel meets the requirements, and its cost is relatively low. It is understood that other materials can also be used for the heat insulation plate 4. The beneficial effect of this embodiment is that cold-rolled steel can meet current assembly requirements and is inexpensive.

[0036] Example 1

[0037] Combined with appendix Figure 2 To be continued Figure 4 The disc 1 is also provided with a plurality of fixing posts 12 for mounting the heat insulation plate 4. The fixing posts 12 are located between every two adjacent rotating gear seats 2 and are evenly spaced around the central axis 13. In this embodiment, the disc 1 is provided with four fixing posts 12, which are evenly distributed around the pressure plate 3; the heat insulation plate 4 is fastened to the four fixing posts 12 of the disc 1 by fasteners, and an air insulation layer 8 is formed between the heat insulation plate 4 and the disc 1 through the fixing posts 12; the heat insulation plate 4 does not come into contact with the disc 1, so the heat on the heat insulation plate 4 cannot be transferred to the disc 1 through contact. The beneficial effect of this embodiment is that the heat insulation plate 4 can be stably installed on the disc 1, and the air insulation layer 8 formed between the fixing posts 12 and the disc 1 effectively isolates the heat transfer on the heat insulation plate 4.

[0038] As a new implementation method, combined with the appendix Figure 4 The height of the fixing post 12 is greater than the installation height of the pressure plate 3. The installation height of the pressure plate 3 is the distance from the upper surface of the pressure plate 3 to the disc 1. That is, when the heat insulation plate 4 is installed on the fixing post 12, the heat insulation plate 4 does not directly contact the pressure plate 3, but there is a certain gap between the heat insulation plate 4 and the pressure plate 3. The heat insulation plate 4 cannot transfer heat to the disc 1 through the pressure plate 3, and the air insulation layer 8 between the heat insulation plate 4 and the pressure plate 3 and the disc 1 can effectively hinder the heat transfer of the heat insulation plate 4. The beneficial effect of this embodiment is that when the height of the fixing post 12 is greater than the installation height of the pressure plate 3, the heat insulation plate 4 cannot transfer heat through direct or indirect contact, which can prevent the high temperature of the heat insulation plate 4 from being transferred to the disc 1 and causing it to deform due to high temperature.

[0039] Example 2

[0040] The difference between Example 2 and Example 1 is that the installation position of the heat insulation board 4 is different.

[0041] Combined with appendix Figure 5 To be continued Figure 6 The heat insulation plate 4 is mounted on the pressure plate 3, and a heat insulation sheet 7 for heat insulation is also provided between the heat insulation plate 4 and the pressure plate 3. In this embodiment, the heat insulation plate 4 is fastened to the pressure plate 3 by fasteners. The pressure plate 3 has four outwardly extending rectangular mounting ears, and the mounting ears have mounting holes for mounting the heat insulation plate 4. The mounting holes are threaded. The heat insulation sheet 7 is a ring-shaped mica sheet, which is located between the heat insulation plate 4 and the pressure plate 3. The disc 1 is also provided with through holes for avoiding the fasteners for mounting the heat insulation plate 4. The beneficial effect of this embodiment is that the heat insulation plate 4 is mounted on the pressure plate 3 and separated from the pressure plate 3 by the heat insulation sheet 7. The heat insulation plate 4 does not contact the disc 1, which helps to hinder the heat transfer of the heat insulation plate 4 and prevent the high temperature of the heat insulation plate 4 from being transferred to the disc 1, causing it to deform due to high temperature.

[0042] The working principle of the technical solution of this utility model is explained as follows, as shown in the appendix. Figure 1 To be continued Figure 7 As shown, the heat insulation plate 4 is installed above the pressure plate 3. The projection of the heat insulation plate 4 can cover the gap area 112, effectively blocking the light from directly shining on the surface of the disk 1. There is a gap between the heat insulation plate 4 and the disk 1, forming an air heat insulation layer 8. The low thermal conductivity of air medium blocks the heat transfer path between the heat insulation plate 4 and the disk 1, so that the heat absorbed by the heat insulation plate 4 cannot be transferred to the disk 1. This prevents the disk 1 from aging and deforming due to heat or continuous irradiation.
