Description

Technical Field

[0001] The invention relates to the field of stage lights, and in particular to a tower-type color mixer used for stage lights. Background Art

[0002] Stage lighting, also known as "stage illumination" or "lighting" for short, is one of the means of stage art modeling. Using stage lighting equipment (such as lighting fixtures, slides, control systems, etc.) and technical means, with the development of the plot, light color and its changes are used to display the environment, render the atmosphere, highlight the central characters, create a sense of stage space and time, shape the external image of the stage performance, and provide necessary lighting effects.

[0003] The color mixer is one of the important components used in stage lights to produce different light color changes. The color mixer is used to switch different layers of color filters in the light path to achieve changes in light color. At present, CMY color mixers are usually used in stage lights to change the color of light. CMY color mixers generally contain four groups of color filters: magenta, cyan, yellow, and CTO color temperature. The control system of the stage light needs to control these four groups of color filters separately to mix different colors of light. Since four different groups of color filters need to be driven separately, and each group of color filters contains multiple combined lenses, this leads to a relatively complex driving structure of the traditional color mixer. On the one hand, the failure rate is high and it is not easy to disassemble and repair. On the other hand, the volume is large and it takes up a lot of space inside the stage light. Summary of the invention

[0019] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 3As shown, an embodiment of the present invention provides a tower-structured color mixer for a stage light, comprising a color mixer fixing plate 2, a motor fixing plate 1, a tower drive assembly 3, a first color mixing disk 41, a second color mixing disk 42, a third color mixing disk 43, a fourth color mixing disk 44, a first motor 51, a second motor 52, a third motor 53 and a fourth motor 54.

[0021] The tower drive assembly 3 includes a fixed shaft 30, a first rotating shaft 31, a second rotating shaft 32, a third rotating shaft 33 and a fourth rotating shaft 34; the lower end of the fixed shaft 30 is vertically fixedly connected to the color mixer fixed plate 2, the third rotating shaft 33 is sleeved on the middle and lower part of the fixed shaft 30 and is rotatably connected to the fixed shaft 30 through a bearing, the second rotating shaft sleeve 32 is in the middle part of the third rotating shaft 33 and is rotatably connected to the third rotating shaft 33 through a bearing, the first rotating shaft 31 is sleeved on the middle part of the second rotating shaft 32 and is rotatably connected to the second rotating shaft 32 through a bearing, and the fourth rotating shaft 34 is sleeved on the upper part of the fixed shaft 30 and is rotatably connected to the fixed shaft 30 through a bearing.

[0023] like Figure 2 As shown, a motor driving circuit board 21 is fixedly connected to a side of the color mixer fixing plate 2 facing away from the motor fixing plate 1, and the motor driving circuit board 21 is electrically connected to the first motor 51, the second motor 52, the third motor 53 and the fourth motor 54 respectively, for driving each motor to work in coordination.

[0024] Furthermore, four positioning sensors 6 are provided on the motor fixing plate 1, and the four positioning sensors 6 are respectively arranged at corresponding heights of the first color mixing disk 41, the second color mixing disk 42, the third color mixing disk 43 and the fourth color mixing disk 44, and are respectively used for positioning sensing of the rotational orientation of the first color mixing disk 41, the second color mixing disk 42, the third color mixing disk 43 and the fourth color mixing disk 44.

[0025] Combination Figures 3 to 7 As shown, the axial height of the second rotating shaft 32 is greater than that of the first rotating shaft 31, so that the upper and lower ends of the second rotating shaft 32 are respectively exposed at the upper and lower ends of the first rotating shaft 31; the axial height of the third rotating shaft 33 is greater than that of the second rotating shaft 32, so that the upper and lower ends of the third rotating shaft 33 are respectively exposed at the upper and lower ends of the second rotating shaft 32; the third rotating shaft 33 and the fourth rotating shaft 34 are separated by a shaft sleeve 35; The upper ends of the first rotating shaft 31, the second rotating shaft 32 and the third rotating shaft 33 are respectively provided with a radially protruding first flange 81, a second flange 82 and a third flange 83, and the lower end of the fourth rotating shaft 34 is provided with a radially protruding fourth flange 84; the first rotating shaft 31 is fixedly connected to the first color mixing disk 41 through the first flange 81, the second rotating shaft 32 is fixedly connected to the second color mixing disk 42 through the second flange 82, the third rotating shaft 33 is fixedly connected to the third color mixing disk 43 through the third flange 83, and the fourth rotating shaft 34 is fixedly connected to the fourth color mixing disk 44 through the fourth flange 84; The lower ends of the first rotating shaft 31, the second rotating shaft 32 and the third rotating shaft 33 are respectively provided with a first pulley 91, a second pulley 92 and a third pulley 93, and the upper end of the fourth rotating shaft 34 is provided with a fourth pulley 94; the first rotating shaft 31 is connected to the first motor 51 through the first pulley 91 and the first synchronous belt 71, the second rotating shaft 32 is connected to the second motor 52 through the second pulley 92 and the second synchronous belt 72, the third rotating shaft 33 is connected to the third motor 53 through the third pulley 93 and the third synchronous belt 73, and the fourth rotating shaft 34 is connected to the fourth motor 54 through the fourth pulley 94 and the fourth synchronous belt 74.

Taking the fourth color mixing disk 44 as an example, three independent color filters 45 and a 0-100% gradient color mixing disk 46 are distributed along the circumferential direction on the fourth color mixing disk 44.

[0027] When the present invention is working, the motor driving circuit board 21 can be used to drive each motor to work in coordination, and the first motor 51, the second motor 52, the third motor 53 and the fourth motor 54 respectively drive the first color mixing disk 41, the second color mixing disk 42, the third color mixing disk 43 and the fourth color mixing disk 44 to rotate independently. When the independent color filter 45 of the color mixing disk rotates to above the light-through hole 10, the light can be processed into the corresponding color; when the 0-100% gradient color mixing disk 46 of the color mixing disk rotates to above the light-through hole 10, the light transparency (intensity) can be adjusted, and when the notch of the color mixing disk rotates to above the light-through hole 10, no processing is done to the light. By mixing and superimposing the four color mixing disks, the color mixing processing of the stage lights can be realized, and lights of any color can be mixed.

[0028] The tower structure color mixer for stage lights provided by the present invention realizes a superimposed color mixing structure of multiple color mixing disks through a tower drive assembly, which has a high degree of integration, can effectively reduce the volume of the color mixer, reduce the space occupied by the color mixer, and improve the space utilization rate inside the stage light. At the same time, the multiple color mixing disks in the present invention are connected to the tower drive assembly by stacking, and the connection structure is simple and highly stable, and has the advantages of easy disassembly and easy maintenance.
