Description

Technical Field

[0003] The optical components of existing stage lights generally include structures such as a light source, a color mixing sheet, a focusing structure, and a light output lens. Among them, the focusing module is an important part of the stage light.

The focusing structure generally includes a focusing lens, a prism, and an atomization lens. The inventor found that: since the existing focusing lens is controlled to move independently and the stroke is detected by a stroke detection Hall, when actually moving the focusing lens, the height positions of the atomization lens and the prism are fixed. In order to prevent the focusing lens from hitting the atomization lens or the prism, the stroke of the focusing lens will be shortened, resulting in a poor light and shadow effect; or in order to achieve a better light and shadow effect, the stroke of the focusing lens is not limited, and the focusing lens will hit the atomization lens or the prism during movement, resulting in damage to the atomization lens or the prism.

[0029] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1

[0031] Please refer to Figures 1 - 3, the focus adjustment structure for stage lights of the present application includes a mounting base plate 1, a fixed base plate 2, a focus lens 3, a prism 4, a diffusing lens 5, and a lifting drive assembly. Both the mounting base plate 1 and the fixed base plate 2 are made of aluminum alloy or stainless steel to enhance the load-bearing capacity of the mounting base plate 1 and the fixed base plate 2. The focus lens 3, the prism 4, and the diffusing lens 5 are all arranged on the fixed base plate 2, and the prism 4 and the diffusing lens 5 are arranged above the focus lens 3. Specifically, the focus lens 3, the prism 4, and the diffusing lens 5 are arranged in sequence from bottom to top, or the focus lens 3, the diffusing lens 5, and the prism 4 are arranged in sequence from bottom to top. The lifting drive assembly is connected to the fixed base plate 2 and is used to drive the fixed base plate 2 to move up and down, thereby driving the focus lens 3, the prism 4, and the diffusing lens 5 to move up and down synchronously to achieve the focus adjustment function. Specifically, in order to prevent the focus lens 3 from hitting the prism 4 or the diffusing lens 5 during the focus adjustment movement, which may cause damage to the prism 4 or the diffusing lens 5, the distance between the prism 4, the diffusing lens 5 and the focus lens 3 is a constant. Exemplarily, during the focus adjustment process, the distance between the prism 4 and the focus lens 3 always remains a constant a, and the distance between the diffusing lens 5 and the focus lens 3 always remains b.

[0032] Specifically, an opening is provided in the central area of the mounting base plate 1, and the fixed base plate 2 is movably arranged at the opening and is adapted to the opening, that is, when the fixed base plate 2 moves to the lowest point, the fixed base plate 2 exactly covers the opening and is on the same horizontal plane as the mounting base plate 1. When the fixed base plate 2 moves upward, the fixed base plate 2 is higher than the mounting base plate 1.

[0033] To facilitate the installation of the focus lens 3, a mounting through hole is provided on the fixed base plate 2, and the focus lens 3 is arranged through the mounting through hole and is fixedly connected to the fixed base plate 2. That is, the top end of the focus lens 3 is higher than the fixed base plate 2, the bottom end of the focus lens 3 is lower than the fixed base plate 2, and it can move up and down synchronously with the movement of the fixed base plate 2.

[0034] To facilitate the installation of the lifting drive assembly, the focus adjustment structure for stage lights further includes a mounting side plate 7. The mounting side plate 7 is arranged at the outer edge of the mounting base plate 1, and the bottom end of the mounting side plate 7 is connected to the mounting base plate 1. At the same time, the plane where the mounting side plate 7 is located is perpendicular to the plane where the mounting base plate 1 is located, so that the mounting base plate 1 and the mounting side plate 7 can form a receiving cavity, and the diffusing lens 5 and the prism 4 are both arranged in the receiving cavity.

[0035] Specifically, the lifting drive assembly includes a first drive motor 61, a first gear set 62, and a first conveyor belt 63. The first drive motor 61 is disposed outside the mounting side plate 7, and the first gear set 62 is disposed inside the mounting side plate 7 and connected to the output end of the first drive motor 61. Exemplarily, the first gear set 62 includes a first driving gear and a first driven gear, which are mounted on the inner side wall of the mounting side plate 7 in a vertically juxtaposed manner. Both ends of the first conveyor belt 63 are respectively disposed on the first gear set 62. To drive the fixed bottom plate 2 to move, the first conveyor belt 63 is connected to the fixed bottom plate 2. Exemplarily, the lifting drive assembly further includes a connecting block, which is simultaneously connected to the first conveyor belt 63 and the fixed bottom plate 2.

[0036] Due to the relatively large weight of the fixed bottom plate 2, to further improve the stability of the fixed bottom plate 2 during movement, the focus adjustment structure for stage lights further includes a linear slide rail. The linear slide rail includes a linear track 81 and a slider 82. The linear track 81 is disposed on the inner side wall of the mounting side plate 7, and the extending direction of the linear track 81 is the up-and-down direction. Exemplarily, the extending direction of the linear slide rail is parallel to the conveying direction of the first conveyor belt 63; the slider 82 is slidably disposed on the linear track 81 and connected to the fixed bottom plate 2. When the first conveyor belt 63 moves, it drives the fixed bottom plate 2 to move synchronously, and then drives the slider 82 connected to the fixed bottom plate 2 to slide on the linear track 81.

[0037] To fix the prism 4 and the atomizing mirror 5 on the fixed bottom plate 2, the focus adjustment structure for stage lights further includes a fixed shaft 9. The fixed shaft 9 is vertically disposed on the fixed bottom plate 2 and is located beside the focus adjustment mirror 3. The prism 4 and the atomizing mirror 5 are respectively rotatably fixed on the fixed shaft 9 through a prism fixing plate 41 and an atomizing mirror fixing plate 51, which is convenient for adjusting the light and shadow effects. Exemplarily, when only the atomizing mirror 5 is needed after the light emitted by the light source passes through the focus adjustment mirror 3, only the atomizing mirror 5 needs to be rotated to the directly above the focus adjustment mirror 3; when only the prism 4 is needed after the light emitted by the light source passes through the focus adjustment mirror 3, only the prism 4 needs to be rotated to the directly above the focus adjustment mirror 3; when both the atomizing mirror 5 and the prism 4 are needed after the light emitted by the light source passes through the focus adjustment mirror 3, only the atomizing mirror 5 and the prism 4 need to be rotated to the directly above the focus adjustment mirror 3 simultaneously to achieve the corresponding light and shadow effects.

[0038] Further, in order to implement the rotation operation of the prism 4, the focus adjustment structure for the stage light further includes a prism transmission assembly 10. The prism transmission assembly 10 includes a second driving motor 101, a second gear set 102, and a second conveyor belt 103. The second driving motor 101 is disposed at the bottom end of the fixed base plate 2. Exemplarily, a through hole is provided on the fixed base plate 2, and the second driving motor 101 is fixed below the through hole, and the output shaft of the second driving motor 101 faces upward and passes through the through hole to reach above the fixed base plate 2. The second gear set 102 is disposed on the fixed base plate 2 and is connected to the second driving motor 101 and the fixed shaft 9. Both ends of the second conveyor belt 103 are respectively disposed on the second gear set 102. Exemplarily, the second gear set includes a second driving wheel and a second driven wheel. The second driving wheel is sleeved on the output shaft of the second driving motor 101 and can rotate with the rotation of the output shaft of the second driving motor 101. The second driven wheel is sleeved on the fixed shaft 9 and is power-connected to the first driving wheel through the second conveyor belt 103. The prism 4 is disposed above the second gear set and is fixedly connected to the second gear set. Exemplarily, the prism 4 is disposed on a prism fixing plate 41. The prism fixing plate 41 and the second driven wheel are sleeved on the fixed shaft 9 from top to bottom in sequence, and the bottom end of the prism fixing plate 41 is fixedly connected to the second driven wheel. When it is necessary to move the prism 4, the second driving motor 101 is driven to drive the second driving wheel, the second conveyor belt, and the second driven wheel to rotate synchronously, thereby driving the prism fixing plate 41 to move synchronously, and further driving the prism 4 to move.

[0039] In order to implement the rotation operation of the atomizing mirror 5, the focus adjustment structure for the stage light further includes a transmission shaft 11 and an atomizing mirror transmission assembly 12. The atomizing mirror transmission assembly 12 includes a third driving motor 121, a third gear set 122, and a third conveyor belt 123. The third driving motor 121 is disposed at the bottom end of the fixed base plate 2. The third gear set 122 is respectively disposed on the fixed shaft 9 and the transmission shaft 11. The transmission shaft 11 is connected to the output end of the third driving motor 121. The atomizing mirror 5 is disposed above the third gear set 122 and is fixedly connected to the third gear set 122. Both ends of the third conveyor belt 123 are respectively disposed on the third gear set 122. When it is necessary to move the atomizing mirror, the third driving motor 121 is driven to drive the third gear set 122 and the third conveyor belt 123 to rotate synchronously, thereby driving the atomizing mirror 5 to move synchronously.

[0040] Further, in order to enrich the light and shadow effects, the focusing structure for the stage light further includes a magnifying glass 13 and a transmission assembly. The magnifying glass 13 is arranged above the atomizing mirror 5 and the prism 4, that is, the light emitted by the light source passes through the focusing lens 3, the prism 4, the atomizing mirror 5 and the magnifying glass 13 in sequence and then is emitted.

[0041] In order to be able to adjust the height of the magnifying glass 13, the transmission assembly includes a fourth driving motor 141, a fourth gear set 142 and a fourth transmission belt 143. The fourth driving motor 141 is arranged outside the mounting side plate 7. Exemplarily, the fourth driving motor 141 and the first driving motor 61 are arranged side by side on the mounting bottom plate 1, and the output end of the fourth driving motor 141 faces the inner side of the mounting side plate 7. The fourth gear set 142 is arranged inside the mounting side plate 7 and is connected to the output end of the fourth driving motor 141. The two ends of the fourth transmission belt 143 are respectively arranged on the fourth gear set 142 and are connected to the magnifying glass 13. Exemplarily, the fourth gear set 142 includes a third driving wheel and a third driven wheel. The third driven wheel is arranged directly above the third driving wheel and is connected by the fourth transmission belt 143 to achieve power connection. The magnifying glass 13 is connected to the fourth transmission belt 143 through a clamp block clamped on the fourth transmission belt 143. When it is necessary to adjust the height of the magnifying glass 13, the fourth driving motor 141 rotates forward to drive the third driving wheel, the third driven wheel and the fourth transmission belt 143 to move synchronously, thereby driving the magnifying glass 13 to descend; conversely, the fourth driving motor 141 rotates reversely to drive the magnifying glass 13 to ascend. In order to further improve the stability of the magnifying glass 13 during operation, the magnifying glass 13 is fixedly connected to the upper slider 83. The upper slider 83 is slidably arranged on the linear track 81 and is located directly above the slider 82. By arranging the upper slider 83 and the slider 82 on the same linear track 81, it is beneficial to simplify the structure and save space.

[0042] Principle:

[0043] For the focusing structure for the stage light provided in the present application, when focusing the light emitted by the light source, only the first driving motor 61 needs to be started to drive the fixed bottom plate 2 to move up and down based on the mounting bottom plate 1, thereby driving the focusing lens 3, the prism 4 and the atomizing mirror 5 to move up and down synchronously to form a clear light spot within different range of illumination of the lamp. Then, when it is necessary to superimpose the light and shadow effects of the prism 4 and / or the atomizing mirror 5, only the second driving motor 101 and / or the third driving motor 121 need to be started to move the prism 4 and / or the atomizing mirror 5 directly above the focusing lens 3. By starting the fourth driving motor 141, the height adjustment of the magnifying glass 13 is realized, thereby further enriching the light and shadow effects of the lamp.

[0044] In the first embodiment of the present application, for the focusing structure of the stage light, a movable fixed base plate is provided on the mounting base plate, and the focusing lens, the prism and the atomizing lens are all fixedly arranged on the fixed base plate, so that the focusing lens, the prism and the atomizing lens can move synchronously with the movement of the fixed base plate, effectively simplifying the focusing steps and improving the focusing efficiency. By setting the distance from the prism / atomizing lens to the focusing lens as a constant, it can effectively prevent the focusing lens from colliding with the prism / atomizing lens when the focusing lens moves, resulting in damage to the prism / atomizing lens. By setting a linear slide rail on the mounting side plate and arranging both the upper slider and the slider on the linear slide rail, it not only further improves the stability of the movement of the fixed base plate and the magnifying glass, but also simplifies the structure and saves space. Compared with the existing focusing structure of the stage light, the focusing structure of the stage light in the present application can avoid shortening the stroke of the focusing lens, effectively preventing the focusing lens from hitting the atomizing lens or the prism, thereby effectively protecting the prism or the atomizing lens from damage. Moreover, the focusing structure of the stage light is simple and compact, easy to adjust, and effectively improves the focusing efficiency.

[0049] In the description of the present application, it should be understood that the orientation or positional relationship indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description. Without contrary explanation, these orientation terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present application; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0050] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "above-mentioned", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to cover different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations are made for the spatial relative descriptions used here.
