Description

Technical Field

[0002] CMY devices are indeed widely used as a color adjustment device in stage lighting. Its core function is to be able to switch colors quickly and accurately as needed. The main way for CMY devices to achieve this function is by moving the position of CMY sheets. CMY sheets are used to absorb or transmit light of a specific color to achieve color adjustment. When the CMY sheet cuts into the stage light beam, it absorbs the light of the corresponding color in the beam, thereby changing the color of the beam. Conversely, when the CMY sheet cuts out of the beam, the color of the beam will be restored. In this way, the CMY device can accurately control the color of the beam and achieve rapid color switching.

[0003] The CMY device in the prior art often occupies a large space because it includes CMY sheets and corresponding drive devices. This is mainly because the CMY sheets need to have a certain area to effectively filter light, and the drive device needs enough space to ensure the accurate and stable movement of the CMY sheets.

DETAILED DESCRIPTION Embodiment 1

[0024] Combination Figure 1 and Figure 2The CMY device comprises a mounting plate 4, a CMY component 1 and a CMY component 2. The mounting plate 4 is used to mount the CMY component 1 and the CMY component 2; the CMY component 1 is located on one side of the mounting plate, and comprises a first drive motor 11, a first transmission component 12 and at least one pair of CMY sheets (121, 122) that move in opposite directions under the action of the first drive motor 11 and the first transmission component 12; the CMY component 2 is located on the other side of the mounting plate opposite to the CMY component 1, and comprises a second drive motor 21, a second transmission component 22 and at least one pair of CMY sheets (221, 222) that move in opposite directions under the action of the second drive motor 21 and the second transmission component 22; and the first drive motor output shaft 111 is perpendicular to the second drive motor output shaft 211. The conventional CMY device occupies a large space in the X direction due to the design that the first drive motor output shaft 111 is parallel to the second drive motor output shaft 211, which makes the structure of the entire device appear not compact enough. The utility model changes the design of the output shaft of the driving motor so that the first driving motor output shaft 111 is perpendicular to the second driving motor output shaft 211, thereby effectively compressing the occupied space in the X direction. This design innovation not only makes the CMY device more compact in structure, but also improves its applicability in a limited space. The beneficial effect of the utility model is that the occupied space in the X direction is effectively compressed, thereby improving the utilization rate of the space.

[0025] As a new implementation method, combined with Figure 2 and Figure 5 , the CMY sheets (121, 122, 221, 222) are staggered up and down in the light emitting direction. The beneficial effect of this embodiment is that the design of staggered distribution of CMY sheets (121, 122, 221, 222) up and down can increase the stroke of CMY sheets (121, 122, 221, 222), so that each CMY sheet can move and adjust the position more effectively. CMY sheets can overlap each other, thereby achieving more accurate and complex filtering of the light beam. In addition, the design of staggered distribution of CMY sheets (121, 122, 221, 222) up and down can also place as many CMY sheets as possible in a limited space.

[0026] As a new implementation method, combined with Figure 2 and Figure 5, the mounting plate 4 is provided with a long strip opening 41 for avoiding the CMY component 1. Conventional CMY devices are generally directly mounted on the mounting plate 4, and no long strip opening 41 is provided for avoiding the CMY component 1. The long strip opening 41 designed in the utility model provides another option, and it is obvious that this option saves more space. The beneficial effect of this embodiment is that the design of the long strip opening 41 allows the CMY component 1 to be mounted on the mounting plate 4 in an indirect manner, which is conducive to reducing the space occupied by the CMY component 1 in the Y direction and reducing the height of the CMY component 1 in the Y direction.

[0027] As a new implementation method, combined with Figures 2 to 3 The CMY component 1 also includes a support plate 13 for installing the first drive motor 11 and the first transmission component 12, and the support plate 13 is inserted into the long strip opening 41. The support plate 13 is not only the basis for installing the first drive motor 11 and the first transmission component 12, but also ensures the stability of the entire system. The first drive motor 11 is installed on one side of the support plate 13, and the first drive motor 11 is equipped with a synchronous pulley 123. When the first drive motor 11 is in motion, it will drive the synchronous pulley 123 to rotate, and the synchronous pulley 123 transfers kinetic energy to the slider through the first belt 124. The CMY sheets (121, 122) fixed on the slider move with the translation of the slider. In this way, the position of the CMY sheets (121, 122) can be accurately controlled. The support plate 13 of the CMY component 1 is perpendicular to the horizontal plane and inserted into the long strip opening 41. The beneficial effect of this embodiment is that the design of the support plate 13 inserted into the long strip opening 41 does not increase the occupied space in the Y direction.

[0028] As a new implementation method, combined with Figure 4 and Figure 5 , the mounting plate 4 is provided with a reserved space 43 for installing other effect disk 42 components, and the reserved space 43 is located at the outer edge of the support plate 13 and the mounting plate 4. The components of the traditional CMY device are generally installed in a manner that the first drive motor output shaft 111 is perpendicular to the horizontal plane, so the space occupied in the X direction is large, and it is difficult to reserve space for installing other effect disk 42 components. The CMY device is installed in combination with other effect disks. Often due to the limitations of structural design and spatial layout, the combined height of the two is the superposition of the single heights, resulting in an overall height that is too large. The beneficial effect of this embodiment is that, if Figure 4 As shown, by optimizing the structural design, space for installing other effect discs 42 is reserved, so that other effect discs 42 can be embedded in the device for installation. This design ensures that the height of the CMY device and the effect disc combination is significantly less than the simple addition of the heights of the CMY device and the effect disc.

[0029] As a new implementation method, combined with Figure 4 The CMY assembly 12 further includes a connecting plate 14, one end of which is connected to the mounting plate 4, and the other end of which is connected to the support plate 13. The connecting plate 14 is a key component for fixing the CMY assembly 1, and the main function of the connecting plate 14 is to firmly fix the CMY assembly 1 installed on the support plate 13 on the mounting plate 4. The beneficial effect of this embodiment is that when the first transmission assembly 12 is working, the connecting plate 14 can ensure that the support plate is fixed at a specific position through its structural characteristics, so that the first transmission assembly 12 can drive the CMY sheets (121, 122) to move smoothly without any interference.

[0030] As a new implementation method, combined with Figures 1 to 3 , the first transmission assembly 12 includes a first belt 124, and the second transmission assembly 22 includes a second belt 224, and the motion path plane of the first belt 124 is perpendicular to the motion path plane of the second belt 224. The working principle of the first transmission assembly 12 and the second transmission assembly 22 is mainly to transmit kinetic energy by the meshing movement between the synchronous pulley (123, 125 or 223, 225) and the belt (124 or 224), and drive the CMY sheet (121, 122 or 221, 222) fixed on the slider to move. There are some problems in the design of the belt motion path of the traditional CMY device. Specifically, when the motion path planes of the first belt 124 and the second belt 224 are parallel, the space they occupy in the X direction will be relatively large. In order to solve this problem, the utility model proposes an innovative solution: the motion path plane of the first belt 124 is designed to be perpendicular to the motion path plane of the second belt 224. The beneficial effect of this embodiment is that this design effectively reduces the occupied space in the X direction, and this vertical design also has another important advantage: it ensures the parallelism of the CMY sheets (121, 122, 221, 222) on the CMY device. Since the movement path planes of the two belts (124, 224) are vertical, the CMY sheets (121, 122, 221, 222) driven by them can be distributed in an up-and-down staggered manner without collision or interference during the movement.

[0031] As a new implementation method, combined with Figure 5 The mounting plate 4 is provided with a light hole 44 located in the direction of the main optical axis. The light hole 44 is located in the center of the mounting plate 4 and serves as a key passage for light to pass through. The beneficial effect of this embodiment is that it ensures that the light emitted by the light source can be located on the same main optical axis, and they can form a more concentrated and clear light beam.

[0032] The utility model provides a stage light having a CMY device, which is generally located between the light source and the light-emitting lens of the stage light and is used to mix the colors of the light emitted by the light source to achieve a more colorful light spot effect. In addition, the CMY device can also be matched with other effect disks, such as pattern disks, cutting disks, apertures, etc. Embodiment 2

[0033] The difference between the second embodiment and the first embodiment is that the second embodiment, in addition to any one of the implementation modes of the first embodiment, further includes a third component 3, combined with Figure 6 and Figure 7 The CMY component three 3 includes a third drive motor 31 and a third transmission component 32. The third drive motor 31 is arranged opposite to the second drive motor 21, and the third drive motor 31 is connected to the second transmission component 22 and the third transmission component 32 respectively. The third drive motor 31 and the third transmission component 32 work in coordination to achieve the translational movement of the CMY sheets (321, 322) in opposite or opposite directions. The beneficial effect of adding the CMY component three is that one more set of CMY sheets (321, 322) is added to the CMY device, and more types of filtering can be performed on the light emitted by the light source, thereby expanding the functional range of the filtering system. Different combinations of CMY sheets can produce various unique color combinations, thereby creating a rich variety of color mixing effects.

[0034] In addition, it can be understood that the CMY sheets (121, 122, 221, 222, 321, 322) of the CMY device in the present invention are general terms, and in practical applications include but are not limited to C / M / Y filters, and can also be M / K filters.
