Description

[0002] With the continuous development of stage light technology, in order to achieve diversified stage light functions and meet the requirements of small size and compact internal structure, usually one or more effects such as color, pattern, and light splitting are integrated onto a composite effect disc to form a multi-ring light transmission ring. For current different light effect requirements, the visual effects required by stage lights are becoming more and more demanding. The stage visual effects are mainly composed of brightness changes and pattern effects, and the pattern effects are changed by changing the patterns projected by lighting equipment, which makes the transmission mechanism of the pattern pieces extremely important for the overall stage visual effects. How smoothly the pattern disc rotates without jitter is particularly important for current stage light products. Currently, most intelligent stage lighting equipment uses single-gear transmission, resulting in the pattern disc being prone to jamming and jitter due to long-term use, and it is difficult to improve the overall user experience.

[0038] Figure 4 is the exploded schematic diagram of the first pattern component 2 and the second pattern component 3 shown in the embodiments of the present utility model.

[0039] Please refer to Figures 1 to 4 , a combined pattern disc for stage lights provided by the embodiments of the present utility model includes a shaft body 1;

[0040] The first pattern component 2 includes a first turntable 21 rotatably connected to the shaft body 1 and a plurality of pattern modules 22 provided on the first turntable 21. The plurality of pattern modules 22 are arranged in a ring around the shaft body 1;

[0041] The second pattern component 3 includes a second turntable 31, a first driving gear disk 32, a second driving gear disk 33, and a plurality of pattern modules 34. The second turntable 31, the first driving gear disk 32, and the second driving gear disk 33 are all rotatably connected to the shaft body 1. The plurality of pattern modules 34 are provided at both ends of the second turntable 31 and correspond to the pattern modules 22. A pattern gear disk 341 is rotatably provided on the pattern module 22. The pattern gear disks 341 at both ends of the second turntable 31 respectively surround the first driving gear disk 32 and the second driving gear disk 33, and the first driving gear disk 32 and the second driving gear disk 33 are meshed with each other;

[0042] At least four transmission systems 4 respectively drive the first turntable 21, the second turntable 31, the first driving gear disk 32, and the second driving gear disk 33 to rotate around their own axes;

[0043] Wherein, light-transmitting holes 8 are provided on both the first turntable 21 and the second turntable 31.

[0044] Specifically, after the device is installed on the stage light, the user can control the four transmission systems 4 through an externally connected control platform or software program. In this embodiment, various pattern pieces of different shapes can be provided on each pattern module 22. The pattern gear disks 341 at both ends of the second turntable 31 can be provided with the same pattern pieces or different pattern disks.

[0045] Therefore, under the above settings, the device can achieve the following light effects.

[0046] When the user needs a single-pattern light effect, it can be achieved through the first pattern component 2 or the second pattern component 3. The specific control process can be carried out in the following manner: If the required single-pattern light effect is provided by the pattern module 22, at this time, the transmission systems 4 are used to drive the first turntable 21 and the second turntable 31 respectively, align the light-transmitting hole 8 of the second turntable 31 with the stage light source, and align the current required pattern module 22 with the light-transmitting hole 8 of the second turntable 31, and the first driving gear disk 32 and the second driving gear disk 33 are not controlled.

[0047] When the user needs a double-pattern light effect, it can be achieved through the cooperation between the pattern gear discs 341 at both ends of the second turntable 31 or the cooperation between the first turntable 21 and the second turntable 31. Specifically, the control process can be carried out as follows. When the cooperation between two opposite pattern gear discs 341 is required, the first turntable 21 is controlled to rotate so that the through holes of the first turntable 21 can correspond to the stage light source. The second turntable 31 is controlled to rotate so that the pattern module 34 that can form a double-pattern light effect at present corresponds to the light-transmitting holes 8 of the first turntable 21. Then, the corresponding pattern gear discs 341 are rotated through the first drive gear disc 32 and the second drive gear disc 33, so that the pattern gear discs 341 cross each other, thereby forming a corresponding pattern light effect. Or, by rotating the first turntable 21 and the second turntable 31 simultaneously, the pattern module 22 corresponds to the pattern module 34, and at this time, the pattern gear discs 341 configured by the pattern modules 34 on the upper and lower layers (i.e., at both ends of the second turntable 31) are the same. At this time, through the first drive gear disc 32 and the second drive gear disc 33, the pattern gear discs 341 on the upper and lower layers are overlapped, and then a pattern effect is formed. Under the irradiation of the stage light source, the light effect of the double-pattern combination is realized.

[0048] When the user needs a triple-pattern light effect, at this time, the first turntable 21, the second turntable 31, and the pattern modules 34 on the upper and lower layers are respectively controlled to rotate through the transmission system 4 to achieve the triple-pattern light effect.

[0049] In practical applications, the number of the pattern modules 22 provided on the first turntable 21 and the pattern modules 34 provided on the second turntable 31 can be set according to the size of the stage light and the actual needs of the user. For example, when the pattern module 22 is set to 6 and the pattern modules 34 on the upper and lower layers are also 6, by using the stage light combined pattern disc provided by the present utility model, up to hundreds of different light effects can be achieved.

[0050] In a possible implementation scheme, please refer to Figure 4 and Figure 5 and in combination with Figure 3 The first pattern component 2 of the above-mentioned stage light combined pattern disc further includes a first transmission wheel 23 and a fastener 24.

The transmission system 4 drives the first driving gear disc 32 and the second driving gear disc 33 to rotate around their own axes through the small-diameter annular tooth 32b.

[0053] In a possible implementation, please refer to Figure 7 , and in combination with Figure 1 and Figure 2 , the transmission system 4 of the above stage light combined pattern disc includes a motor 41, a belt pulley 42, and a synchronous belt 43. The motor 41 is connected to the belt pulley 42. The first end of the synchronous belt 43 meshes with the belt pulley 42, and the second end of the synchronous belt 43 is meshed and connected to the first transmission wheel 23, the second transmission wheel 36, and the small-diameter annular tooth 32b respectively.

[0054] In a preferred embodiment, the motor 41 can be a stepper motor 41.

[0055] A stepper motor 41 is a motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. For each input pulse signal, the rotor rotates an angle or moves forward one step. Its output angular displacement or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency.
