Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and more specifically, to a patterned sheet heat dissipation device and a lamp having the same. Background Technology

[0002] In the field of stage lighting technology, stage lighting imaging is primarily achieved through a rotating pattern disk assembly. This assembly contains multiple pattern pieces, any one of which can be switched to the main optical axis position for projection. Due to the requirements of image clarity, the rotating pattern disk assembly is usually located close to the light source. However, the light emitted by the light source generates significant heat, causing the pattern piece located on the main optical axis to overheat and rise in temperature, leading to problems such as distorted light effects, color shifts, or uneven light spots. Currently, existing heat dissipation technologies mainly target the entire rotating pattern disk assembly, making it difficult to precisely reduce the temperature of the pattern piece located on the main optical axis, thus failing to effectively solve the imaging problems caused by pattern piece overheating. Summary of the Invention

[0003] This invention provides a pattern sheet heat dissipation device and a lamp having the same, which can accurately dissipate heat from any pattern sheet located on the main optical axis.

[0004] On one hand, a pattern plate heat dissipation device includes a rotating pattern plate assembly, a heat dissipation component located on the side of the rotating pattern plate for heat dissipation of the rotating pattern plate assembly, a first mounting plate, and a second mounting plate; the rotating pattern plate assembly is located between the first mounting plate and the second mounting plate, and the heat dissipation component includes a fan and an air guide connected to the fan outlet, the air guide including an air inlet and an air outlet; the air outlet faces the intersection of the main optical axis and the rotating pattern plate assembly, and the fan blows the air above the rotating pattern plate assembly through the air outlet to the intersection of the main optical axis and the rotating pattern plate assembly.

[0005] As a further improvement of this utility model, the air guide includes an air guide part one that communicates with the air outlet of the fan and an air guide part two that is located below the air guide part one and smoothly transitions thereto. The air guide part one is parallel to the main optical axis, and the air outlet end of the air guide part two faces the intersection of the main optical axis and the rotating pattern disk assembly.

[0006] As a further improvement of this utility model, the first air guide is perpendicular to the second air guide.

[0007] As a further improvement of this utility model, the air guide component is integrally formed.

[0008] As a further improvement of this utility model, the air guide part one and the air guide part two of the air guide are inserted and connected.

[0009] As a further improvement of this utility model, the second air guide is located below the rotating pattern disk assembly.

[0010] As a further improvement of this utility model, both the first air guide section and the second air guide section are elongated structures, and the width of both the first air guide section and the second air guide section is smaller than the width of the fan.

[0011] As a further improvement of this utility model, the rotating pattern disk assembly includes a revolving disk and a pattern piece mounted on the disk that can rotate on its own axis, wherein the straight-line distance between the air outlet end and the main optical axis is greater than the radius of the pattern piece.

[0012] As a further improvement of this utility model, the rotating pattern disk assembly also includes a drive motor mounted on the mounting plate 2, the drive motor being used to drive the disk.

[0013] On the other hand, a lamp includes a patterned sheet heat dissipation device as described in any of the above claims, and further includes a housing, a light source, and a lens assembly, wherein the light source, the lens assembly, and the heat dissipation device are located within a cavity enclosed by the housing.

[0014] This utility model proposes a patterned sheet heat dissipation device and a lamp having the same, which has the following advantages compared with traditional patterned sheet heat dissipation devices:

[0015] (1) The heat dissipation device in this technical solution draws in cold air from inside the lamp through a fan, and blows it towards the intersection of the main optical axis and the rotating pattern disk through the air guide. When the rotating pattern disk assembly is in operation, the intersection of the main optical axis and the rotating pattern disk assembly is the pattern piece, that is, the technical solution achieves precise heat dissipation of the pattern piece. (2) The heat dissipation component is installed on the side of the mounting plate one, and the air guide part one is parallel to the main optical axis. Both the air guide part one and the air guide part two are long strip structures, so that the volume occupied by the heat dissipation component in the direction perpendicular to the main optical axis is relatively minimized, saving space inside the lamp.

Detailed Implementation

[0020] Combined with appendix Figure 1 and attached Figure 2 A patterned plate heat dissipation device and a lamp having the same, comprising a rotating patterned plate assembly 2, a heat dissipation assembly 1, a mounting plate 3, and a mounting plate 4.

[0021] Mounting plate 3 is a rectangular flat plate with a circular through hole in the middle. Mounting plate 3 includes two opposite sides for mounting and fixing and a side 31 for mounting heat dissipation component 1. All three sides are provided with mounting holes for mounting. The two sides for mounting and fixing on mounting plate 3 are fixedly connected to mounting plate 4 through two identical rectangular flat plates, so that mounting plate 3 is stably mounted on mounting plate 4.

[0022] Mounting plate 2 4 is located below mounting plate 1 3. Mounting plate 2 4 is a flat plate with four bent edges, two of which have mounting holes for fixing mounting plate 1 3 on two opposite bent edges. Mounting plate 2 4 also has multiple mounting holes for fixing to the inside of the lamp. Mounting plate 2 4 is installed inside the lamp through multiple mounting holes.

[0023] The rotating pattern disk assembly 2 is located between mounting plate 3 and mounting plate 4, and includes a circular disk 21 that can revolve and multiple pattern pieces 22 that can rotate on the disk. The multiple pattern pieces 22 alternately cut into the main optical axis 7 through the revolution of the disk 21, ensuring that only one pattern piece 22 is on the main optical axis 7 at the same time. The pattern piece 22 can also rotate on its own axis.

[0024] The heat dissipation assembly 1 is installed on the side of the rotating pattern disk assembly 2, and a mounting plate is provided on it. The mounting plate is locked to the fan 12 and is installed on the side 31 of the mounting plate 3 by fasteners. The heat dissipation assembly 1 includes an air guide 11 and a fan 12. The air guide 11 includes an air inlet 113 and an air outlet 114. The air inlet 113 of the air guide 11 is connected to the air outlet 122 of the fan 12. The air outlet 114 is a funnel shape that is inclined towards the intersection of the main optical axis 7 and the rotating pattern disk assembly 2. The fan 12 can blow air accurately to the intersection of the main optical axis 7 and the rotating pattern disk assembly 2 through the air outlet 114.

[0025] Air above the rotating pattern disk assembly 2 enters the air guide 11 through the fan 12, and is then transported to the air outlet 114 through the air guide 11. Finally, the fan 12 blows the air from the air outlet 114 to the intersection of the main optical axis 7 and the rotating pattern disk assembly 2. When the rotating pattern disk assembly is in operation, the intersection of the main optical axis 7 and the rotating pattern disk assembly 2 is the pattern piece. At this time, the fan 12 continuously delivers air to the pattern piece 22 located on the main optical axis 7 through the air outlet 114, thereby achieving all-round heat dissipation of the pattern piece 22.

[0026] The beneficial effect of this embodiment is that the fan 12 can accurately blow the air above the rotating pattern disk assembly 2 toward the pattern piece 22 located on the main optical axis 7, effectively reducing the temperature of the pattern piece 22; and the heat dissipation assembly 1, which is vertically installed on the side of the rotating pattern disk assembly 2, can save space to the greatest extent.

[0027] As a new implementation method, combined with the appendix Figure 1 and attached Figure 2 The air guide 11 includes an air guide section 111 and an air guide section 112. The fan 12 includes an air inlet 121 and an air outlet 122. The fan 12 is vertically mounted above the air guide section 111, which is parallel to the main optical axis 7 and vertically mounted on the side of the rotating pattern disk assembly 2, thus optimizing the space occupied by the heat dissipation component 1 inside the lamp. The air guide section 111 is connected to the air outlet 122 of the fan 12. The air guide section 111 is located above the air guide section 112 and smoothly transitions with it. The air outlet 114 of the air guide section 112 faces the intersection of the main optical axis 7 and the rotating pattern disk assembly 2. The air inlet 121 of the fan 12 draws air from above the rotating pattern disk assembly 2 into the fan 12. The air inside the fan 12 is then transported through the air inlet 113 of the air guide section 111 to the interior of the air guide section 111 by the air outlet 122. The air in the air guide section 111 flows through the air guide section 212, and the fan 12 blows the air to the intersection point through the air outlet 114 of the air guide section 2. When the rotating pattern disk assembly 2 is in operation, the intersection point is the pattern piece 22 located on the main optical axis 7, which achieves targeted heat dissipation of the pattern piece 22 located on the main optical axis 7. The beneficial effect of this embodiment is that the fan 12, the first air guide 111 and the second air guide 112 are connected, which allows the air drawn in by the fan 12 to flow smoothly through the first air guide 111 and the second air guide 112, and then blown through the air outlet 114 to the intersection of the main optical axis 7 and the rotating pattern disk assembly 2; the first air guide is parallel to the main optical axis, so that the volume occupied by the heat dissipation component inside the lamp is relatively minimized.

[0028] As a new implementation method, combined with the appendix Figure 2The air guide 11 includes an air guide section 111 and an air guide section 112, with the air guide section 111 and the air guide section 112 perpendicular to each other. In conventional heat dissipation devices, two opposing fans are usually installed on both sides of the rotating pattern disk. However, due to the compact installation space of the rotating pattern disk, the air blown by the two fans cannot effectively reach the intersection of the rotating pattern disk and the main optical axis, i.e., to provide targeted heat dissipation for the pattern pieces located on the main optical axis. In this embodiment, the air guide 11 has an L-shaped structure, which perfectly matches the installation structure of the rotating pattern disk assembly 2. The air outlet 114 of the air guide section 112 faces the intersection of the main optical axis 7 and the rotating pattern disk assembly 2. After being guided by the air guide section 111 and the air guide section 112, the air blown by the fan 12 can directly reach the intersection of the rotating pattern disk assembly 2 and the main optical axis 7, i.e., to provide targeted heat dissipation for the pattern pieces 22 located on the main optical axis 7. The beneficial effect of this embodiment is that the vertically installed air guide part 111 and air guide part 112 are more compatible with the installation structure between the rotating pattern disk assembly 2, the mounting plate 13 and the mounting plate 24, and can accurately guide the air to the intersection of the rotating pattern disk assembly 2 and the main optical axis 7, that is, can perform targeted heat dissipation on the pattern piece 22 located on the main optical axis 7.

[0029] As a new implementation method, combined with the appendix Figure 1 The air guide component 11 is integrally formed. The air guide component 11 has an L-shaped structure, with air guide section one 111 mounted on the side of mounting plate one 3, and air guide section two 112 located between mounting plate one 3 and mounting plate two 4. The advantage of this embodiment is that the integrally formed air guide component 11 avoids the connection and assembly between air guide section one 111 and air guide section two 112, and only air guide section one 111 needs to be mounted on mounting plate one 3, while air guide section two 112 does not need to be installed and fixed, simplifying the installation steps of the air guide component 11.

[0030] As a new implementation method, combined with the appendix Figure 2 and attached Figure 3 The air guide section 111 and the air guide section 112 are connected by an insertion. In this embodiment, the air guide section 112 is mounted on the mounting plate 2 4, and the lower surface of the air guide section 111 is in close contact with the upper surface of the mounting plate 2 4, which makes the installation of the air guide section 111 more stable; the dimensions of the air guide section 111 and the air guide section 112 are compatible, and the air guide section 111 can be smoothly inserted into the air guide section 112; the cross-sectional area of ​​the lower end of the air guide section 111 is smaller than the cross-sectional area of ​​the left end of the air guide section 112, so that all the air flowing through the air guide section 111 can enter the air guide section 112, avoiding air leakage. The beneficial effect of this embodiment is that, due to the compact installation structure of the rotating pattern disk assembly 2 and the insertion connection of the air guide section 111 and the air guide section 112, the installation of the air guide section 112 and the air guide section 111 is more convenient.

[0031] As a new implementation method, combined with the appendix Figure 3 The second air guide section 112 is located below the rotating pattern disk assembly 2. When the air guide component 11 is integrally formed, the second air guide section 112 is suspended below the rotating pattern disk assembly 2, and the air guide component 11 can guide the air above the rotating pattern disk assembly 2 to its lower part. In this embodiment, the first air guide section and the second air guide section are inserted and connected, and the second air guide section 112 is directly welded to the second mounting plate 4. The second mounting plate 4 is provided with a rectangular through hole, and the second air guide section 112 is adjacent to the rectangular through hole. The second air guide section 112 is located within the range of the second mounting plate 4, and the second air guide section 112 is installed in the gap between the rotating pattern disk assembly 2 and the second mounting plate 4, and does not interfere with the rotating pattern disk assembly 2. It can be understood that the second air guide section 112 can also be installed on the second mounting plate 4 in other ways. The beneficial effect of this embodiment is that the second air guide section 112 is located below the rotating pattern disk assembly 2, and the air guide component 11 can guide the air above the rotating pattern disk assembly 2 to its lower part.

[0032] As a new implementation method, combined with the appendix Figure 1 and attached Figure 2 Both air guide section 111 and air guide section 112 are elongated structures, and their widths are smaller than the width of the fan 12. The cross-sectional shape of both air guide section 111 and air guide section 112 is rectangular, allowing air guide section 111 to fit more closely to the side 31 of the mounting plate 3. Furthermore, the width design of air guide section 111 ensures that while installed on the side 31, it does not exceed the area enclosed by the boundary of the mounting plate 3.

[0033] The structure of the second air guide 112 allows for a more stable installation on the second mounting plate 4, and its width design ensures that the second air guide 112 will not interfere with the rotating pattern disk assembly 2. The advantages of this embodiment are that the first air guide 111 can be installed more closely to the side of the first mounting plate 3, and the second air guide 112 will not interfere with the rotating pattern disk assembly 2 when installed on the second mounting plate 4; the shapes of the first air guide 111 and the second air guide 112 facilitate targeted heat dissipation of the pattern sheet 22 while using minimal space.

[0034] As a new implementation method, combined with the appendix Figure 1 and attached Figure 2The rotating pattern disk assembly 2 includes a revolving disk 21 and a rotatable pattern piece 22 mounted on the disk 21. The distance between the air outlet 114 and the main optical axis 7 is greater than the radius of the pattern piece 22. The air outlet 114 is located between the mounting plate 2 and the rotating pattern disk assembly 2, i.e., at the edge of the through hole in the mounting plate 2. The projection of the air outlet 114 in the direction of the disk 21 is located on the periphery of the pattern piece 22 on the main optical axis 7. This ensures that the air outlet 114 does not block the emitted light rays projected onto the pattern piece 22 on the main optical axis 7, thus not affecting the imaging of the pattern piece 22 on the main optical axis 7. The beneficial effect of this embodiment is that it can effectively dissipate heat from the pattern piece 22 on the main optical axis 7 while ensuring that the air outlet 114 does not affect the normal imaging of the pattern piece 22.

[0035] As a new implementation method, combined with the appendix Figure 1 The rotating pattern disk assembly 2 also includes a drive motor 23 mounted on a mounting plate 2 3, which drives the disk 21. The mounting plate 2 3 has two circular through holes for mounting the drive motor, and the drive motor 23 is mounted on the lower surface of the mounting plate 2 3. When the drive motor 23 is working, the disk 21 revolves, causing multiple pattern pieces 22 to alternately engage with the main optical axis 7. Simultaneously, the pattern pieces 22 mounted on the disk 21 can also rotate. When the disk 21 revolves, the heat dissipation assembly 1 can precisely dissipate heat from the pattern pieces 22 engaging with the main optical axis 7. The beneficial effect of this embodiment is that the drive motor 23 drives the disk 21 to rotate, allowing the heat dissipation assembly 1 to flexibly dissipate heat from any pattern piece 22 located on the main optical axis 7 on the rotating pattern disk assembly 2.

[0036] This utility model provides a lamp, including the heat dissipation device described in any of the above claims, and further including a housing 10, a light source 5, and a lens assembly 6. The light source 5, the lens assembly 6, and the heat dissipation device are located within the cavity enclosed by the housing 10. The light source assembly 5 is located below the through hole of the mounting plate 4, and the lens assembly 6 is located above the rotating pattern disk assembly 2. The light emitted by the light source 5 passes through the through hole of the mounting plate 3 and is projected onto the pattern piece 22 located on the main optical axis 7, causing the temperature of the pattern piece 22 to rise rapidly. To effectively address this situation, the heat dissipation assembly 1 can transport the air above the rotating pattern disk assembly 2 to the pattern piece 22 located on the main optical axis 7, forming a complete airflow path within the cavity enclosed by the housing 10.

[0037] In summary, the fan 12 has air inlets 121 on both sides, which draw air in from above the rotating pattern disk assembly 2. The air outlet 122 then delivers the drawn-in air through the air inlet 113 of the first air guide section 111. Since the lower end of the first air guide section 111 is connected to the left end of the second air guide section 112, the air inside the first air guide section 111 flows smoothly to the second air guide section 112. The air outlet 114 of the second air guide section 112 faces the intersection of the main optical axis 7 and the rotating pattern disk assembly 2, i.e., towards the pattern piece 22 located on the main optical axis 7. Therefore, the air flowing through the second air guide section 112 is precisely blown onto the pattern piece 22 located on the main optical axis 7 via the air outlet 114, thereby achieving targeted heat dissipation for the pattern piece 22.

[0038] It is understandable that the drive motor 23 drives the rotating pattern disk assembly 2 to rotate, so the pattern pieces 22 on the rotating pattern disk assembly 2 alternately cut into the main optical axis 7, that is, the heat dissipation assembly 1 can perform targeted heat dissipation on any pattern piece 22 located on the main optical axis 7.
