Description

Technical Field

[0001] The present invention relates to the technical field of stage lights, and more particularly to a flat effect module and a stage light having the same. Background Art

[0002] As an important equipment for rendering atmosphere, stage lights are widely used in various activity venues. Usually, various effect discs for producing light effects are set in stage lights to improve the rendering effect. The effect disc is usually set near the focal position of the stage light source, but the position near the focal point of the light source is very limited, and it is impossible to set up many effect discs. In addition, the effect disc is generally fixed on a slender pivot shaft and driven by a motor through a belt / gear or directly fixed on the shaft of a rotary motor. On the one hand, the pivot shaft and the shaft of the motor will occupy a certain height space in the direction perpendicular to the effect disc. On the other hand, the thickness of the rotary motor itself will also occupy a certain height space, resulting in a limited number of effect discs arranged at the focal position of the light source, and the effect of the stage light is not rich enough. Summary of the invention

[0003] In order to overcome at least one defect of the above-mentioned prior art, the present invention provides a flat effect module, which eliminates the rotating shaft of the motor and reduces the thickness of the motor itself, so that more effect disks can be arranged at the focal position of the light source, making the effect of the stage light more gorgeous.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a flat effect module, including a first flat motor and an effect disk assembly driven by the first flat motor, the first flat motor including a first stator that generates a magnetic field when energized, and a first rotor that is sleeved outside the first stator and driven by the magnetic field, the effect disk assembly is fixed to the first rotor, and the effect disk assembly includes a disk body for generating light effects, and the disk body has an effect area for intercepting a light beam and changing its color and / or shape.

[0005] The flat effect module can be provided with more permanent magnets on the first rotor compared to the traditional shaft-type motor by sleeve-arranging the first rotor outside the first stator. Therefore, even if the height of each permanent magnet is reduced, the power of the motor will not change due to the increase in the number of permanent magnets, thereby reducing the thickness of the motor itself and saving height space; in addition, the first flat motor does not have the shaft of the traditional shaft-type motor, but directly fixes the effect disk assembly to the first rotor, saving the height of the shaft. The flat effect module saves height space by using the flat motor, which is conducive to arranging more effect disks at the focal position of the light source, thereby making the effects of the stage light richer.

[0006] Furthermore, the first stator includes a first core column and a first winding group wound outside the first core column, and the first core column has a through hole along the length direction. A cable for transmitting power or signals can pass through the through hole, which is convenient for cable installation and arrangement.

[0007] Furthermore, a flange for carrying the effect disc assembly is formed on the first rotor, and the outer diameter of the flange is larger than the outer diameter of the first rotor. The effect disc assembly is fixed to the flange, and the height of the effect disc assembly can be flexibly adjusted by changing the position of the flange, without being limited to the end surface of the effect disc assembly, and the outer diameter of the flange is larger than the outer diameter of the first rotor, so that the effect disc assembly can be fixed more firmly and is not easy to shake relative to the first rotor.

[0008] Furthermore, the first rotor supports the effect disc assembly around the rotation center of the effect disc assembly. The first rotor supports the effect disc assembly in a whole circle around the rotation center of the effect disc assembly, so that the rotation of the effect disc assembly is more stable.

[0009] Furthermore, the disk is directly fixed to the first rotor, and the first rotor drives the disk to rotate. The first rotor drives the disk to rotate, so that different effect areas or different parts of the effect areas on the disk intercept the light beam to produce different light effects. For example, the disk can be a fixed pattern disk, a color plate, a CMY disk or an atomized disk.

[0010] Furthermore, the effect disk assembly further includes a bearing plate, the disk body is pivotally connected to the bearing plate, the bearing plate is fixed to the first rotor, and the first rotor drives the disk body to revolve. The first rotor drives the disk body to move to different positions through the bearing plate, so that the disk body cuts into / out of the light path, or different effect areas on the disk body or different parts of the effect areas intercept the light beam. For example, the disk body can be a fire disk or a prism.

[0011] Furthermore, another first flat motor is fixed on the carrier plate, and the disc is fixed to the first rotor of the first flat motor. The combination of the disc and another first flat motor also has the characteristics of low height and stable rotation.

The first flat motor drives the effect sheet to revolve through the disk body, and the second rotor of the second flat motor is connected to a driving wheel to drive the rotating seat provided with the effect sheet to rotate, thereby realizing the self-rotation of the effect sheet, making the effect of the stage light richer. For example, the disk body can be a rotating pattern disk, or a prism disk, that is, the effect sheet can be a pattern sheet or a prism.

[0013] Furthermore, the first rotor includes a ring body and a permanent magnet disposed on the ring body, the ring body is connected to a shroud, the shroud is sleeved outside the second rotor, and the disk is fixed to the top of the shroud. The first flat motor and the second flat motor are arranged in a superimposed manner, and the shroud is sleeved outside the second rotor, and the disk is fixed to the top of the shroud, so that the disk and the driving wheel can be closer, thereby reducing the height of the rotating seat, and the overall height of the flat effect module is still low.

[0014] Furthermore, the first stator includes a first core column and a first winding group wound outside the first core column, the second stator includes a second core column and a second winding group wound outside the second core column, and the first core column and the second core column are designed as one body. By designing the first core column and the second core column as one body, the shell thickness of the first flat motor and the second flat motor can be omitted, and the first flat motor and the second flat motor can be directly designed as one body, which has a more compact structure and a lower height.

[0015] Furthermore, the first stator and the first rotor, and the second stator and the second rotor are connected via bearings, and the inner rings of the two bearings are supported by support rings. The support rings can space the two bearings apart from each other to prevent the rotation of the first rotor and the second rotor from affecting each other.

DETAILED DESCRIPTION

[0031] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0033] The flat effect module sets the first rotor 120 outside the first stator 110. Compared with the traditional shaft-type motor, more permanent magnets 124 can be set on the first rotor 120. Therefore, even if the height of each permanent magnet 124 is reduced, the power of the motor will not change due to the increase in the number of permanent magnets 124, thereby reducing the thickness of the motor itself and saving height space; in addition, the first flat motor 100 does not have the shaft of the traditional shaft-type motor, but directly fixes the effect disk assembly to the first rotor 120, saving the height of the shaft. The flat effect module saves height space by using the flat motor, which is conducive to arranging more effect disks at the focal position of the light source, thereby making the effects of the stage light richer.

[0034] Optionally, the effect disc assembly is fixed to the end surface of the first rotor 120. This prevents the first rotor 120 from protruding from the effect disc assembly and affecting the operation of other components, thereby facilitating modular design.

[0036] In this embodiment, the first stator 110 includes a first core column 111 and a first winding group 112 wound around the first core column 111.
