Description

Technical Field

[0001] This utility model relates to the field of stage lighting equipment technology, and in particular to a short-throw touch screen follow spot. Background Technology

[0002] Follow spots are core lighting equipment used in stage performances, television broadcasts, and other settings to highlight main actors or targets, requiring high brightness, controllable beam size, and clear focusing capabilities. Traditional follow spots typically use physical knobs, buttons, or external remote controls, making adjustments less intuitive and convenient, especially in stage environments requiring rapid response to changes. Furthermore, many basic models still rely on manually adjusting the zoom lens assembly and / or the relative position of the light source and reflector to achieve zooming and focusing. This method is slow, inaccurate, and difficult to adjust in real-time during performances. In short, traditional follow spots lack a highly integrated, intuitive touchscreen control interface to uniformly manage core functions such as light source switching, focusing, zooming, and heat dissipation. Utility Model Content

[0003] The purpose of this invention is to provide a short-throw touchscreen follow spot that is intuitive and convenient to operate, and allows for precise and rapid adjustment.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a short-throw touch screen follow spot lamp, including a housing and a light source, a reflector, a zoom lens and a heat sink disposed within the housing, and also including a first motor and a second motor disposed within the housing. The first motor is movably connected to the reflector by a first transmission mechanism, and the second motor is movably connected to the zoom lens by a second transmission mechanism. A touch screen is disposed outside the housing. The touch screen is electrically connected to the light source, the first motor, the second motor and the heat sink, and is used to control the opening and closing of the light source and the heat sink, and to control the first motor to drive the reflector closer to or away from the light source through the first transmission mechanism, and to control the second motor to drive the zoom lens closer to or away from the reflector through the second transmission mechanism.

[0005] By adopting the above technical solution, the operator can control the light source and heat sink to turn on and off through the touch screen, and control the first and second motors to rotate forward and backward. The worm gear transmission drives the reflector and zoom lens to move forward and backward, making the operation intuitive and convenient, and the adjustment precise and fast.

[0006] A further feature of this invention is that it includes a first support plate horizontally fixedly disposed at the bottom of the housing, the first support plate and the bottom of the housing together defining a first space for accommodating electrical connection components.

[0007] By adopting the above technical solution, all circuits of the follow spot can be inspected and repaired simply by removing the bottom casing. The layout is reasonable and the maintenance is convenient.

[0008] A further feature of this invention is that: a second support plate and a third support plate are provided on the first support plate, the second support plate and the housing together form a second space to accommodate the radiator, and the top and bottom of the housing are provided with heat dissipation vents corresponding to the positions of the second space.

[0009] By adopting the above technical solution, the heat dissipation vents at the top and bottom of the casing form air convection, enabling the radiator to dissipate heat quickly.

[0010] A further feature of this invention is that it includes a deep atomizing plate, a light atomizing plate, and a third motor disposed on a third support plate. The third motor is movably connected to the deep atomizing plate and the light atomizing plate via a third transmission mechanism, which controls the third motor to drive the deep atomizing plate and the light atomizing plate to rotate, thereby forming a first working state using the deep atomizing plate and a second working state using the light atomizing plate.

[0011] By adopting the above technical solution, the operator controls the third motor to rotate through the touch screen, thereby driving the third transmission mechanism to rotate, so that the illumination position of the light source can switch back and forth between the deep atomizing plate and the light atomizing plate, thus switching between different soft light effects.

[0012] A further feature of this invention is that a first limiting post is fixedly provided on the third support plate, the first limiting post being located on the rotation path of the third transmission mechanism, and used to constrain the rotation angle of the deep atomizing plate and the light atomizing plate.

[0013] By adopting the above technical solution, excessive rotation can be prevented from interfering with other internal parts, which could lead to transmission failure and damage to parts, thus ensuring safe operation.

[0014] A further feature of this invention is that it includes a filter at least partially located within the housing; a slot for accommodating the filter is fixedly provided on the third support plate; the slot extends through to the top of the housing to form an insertion port; and a second limiting post is fixedly provided on the third support plate, located at the end of the slot, for constraining the displacement path of the filter along the slot.

[0015] By adopting the above technical solution, the filter can be installed and removed by simply plugging and unplugging it, making the operation convenient.

[0016] A further feature of this invention is that a gripping part is movably provided at the bottom of the housing, the gripping part having a movable state relative to the housing and a locked state fixed on the housing.

[0017] By adopting the above technical solution, the fulcrum of the grip is changed, thereby achieving a more effortless grip and simpler, less strenuous operation.

[0018] A further feature of this invention is that the gripping part includes a movable plate that abuts against the housing, a bolt is fixedly provided at the bottom of the housing, and a knob is provided below the movable plate. The knob and the bolt together form a locked state and a movable state of the movable plate relative to the housing.

[0019] By adopting the above technical solution, and by setting knobs and bolts to control the locking and moving states of the movable plate relative to the housing, the operation is simple and labor-saving.

[0020] A further feature of this invention is that a third limiting post is fixedly provided at the bottom of the housing, and a groove is provided on the movable plate to accommodate the third limiting post. The groove and the third limiting post together form a path that constrains the displacement of the movable plate along the groove.

[0021] By adopting the above technical solution, the gripping part is prevented from detaching from the housing during the sliding process, ensuring a more stable and safe sliding operation.

[0022] A further feature of this invention is that a fourth support plate is vertically arranged on the first support plate, the fourth support plate being located to the right of the third support plate. The first support plate, the third support plate, and the fourth support plate together define a third space for accommodating the zoom lens, and the first support plate and the fourth support plate together define a fourth space for accommodating the reflector. The third support plate and the fourth support plate together form a path that constrains the zoom lens along the axial direction of the follow spot lamp, and the fourth support plate forms a path that constrains the reflector along the axial direction of the follow spot lamp.

[0023] By adopting the above technical solution, the zoom lens slides in the third space and the reflector slides in the fourth space, preventing mutual interference and resulting in a reasonable layout.

[0024] In summary, this utility model has the following beneficial effects:

[0025] 1. It adopts a touch screen display, which allows the operator to control the light source and heat sink to turn on and off, as well as control the first and second motors to rotate forward and backward. The transmission mechanism drives the reflector and zoom lens forward and backward, making the operation intuitive and convenient, and the adjustment precise and fast.

[0026] 2. A first support plate is installed at the bottom inside the housing, and an electrical connection assembly is installed between the first support plate and the bottom of the housing. All electrical connection assemblies are concentrated in the first space. All circuits of the follow spot can be inspected and repaired simply by removing the bottom housing. The layout is reasonable and the maintenance is convenient.

[0027] 3. The grip is movable at the bottom of the casing, which can change the fulcrum of the grip, thereby achieving a more effortless grip and simple operation. Attached Figure Description

[0037] The present invention will be further described below with reference to the accompanying drawings.

[0038] A short-throw touchscreen follow spot, such as Figure 1-8As shown, the device includes a housing 11 and a light source 12, a reflector 13, a zoom lens 14, and a heat sink 15 disposed within the housing 11. It also includes a first motor 21 and a second motor 31 disposed within the housing 11. A first transmission mechanism 22 is movably connected between the first motor 21 and the reflector 13, and a second transmission mechanism 32 is movably connected between the second motor 31 and the zoom lens 14. A touch screen 4 is disposed outside the housing 11. The touch screen 4 is electrically connected to the light source 12, the first motor 21, the second motor 31, and the heat sink 15, and is used to control the opening and closing of the light source 12 and the heat sink 15, as well as to control the first motor 21 to move the reflector 13 closer to or away from the light source 12 via the first transmission mechanism 22, and to control the second motor 31 to move the zoom lens 14 closer to or away from the reflector 13 via the second transmission mechanism 32. The heat sink 15, light source 12, zoom lens 14, and reflector 13 are arranged sequentially from left to right inside the housing 11. The first transmission mechanism 22 and the second transmission mechanism 32 are both worm gear drives. The reflector 13 and the zoom lens 14 are located on the transmission path of the worm gear drive. The touch screen 4 is located in the same circuit as the heat sink 15, the light source 12, the zoom lens 14, the reflector 13, the first motor 21, and the second motor 31. The operator controls the light source 12 and the heat sink 15 to turn on and off through the touch screen 4, and controls the first motor 21 and the second motor 31 to rotate forward and backward. The worm gear drive pushes the reflector 13 and the zoom lens 14 forward and backward. The operation is intuitive and convenient, and the adjustment is precise and fast.

[0039] Preferably, it further includes a first support plate 16 horizontally fixedly disposed at the bottom of the housing 11. The first support plate 16 and the bottom of the housing 11 together define a first space 111 for accommodating electrical connection components. The first space 111 is the area between the bottom of the first support plate 16 and the top of the housing 11. All electrical connection components of the follow spot are concentrated in the first space 111. All circuits of the follow spot can be inspected and repaired simply by removing the bottom housing 11. The layout is reasonable and the maintenance is convenient.

[0040] Preferably, the first support plate 16 is provided with a second support plate 17 and a third support plate 18. The second support plate 17 and the housing 11 together form a second space 222 to accommodate the heat sink 15. The top and bottom of the housing 11 are provided with heat dissipation vents 151 corresponding to the positions of the second space 222. The second support plate 17 and the third support plate 18 are vertically fixed on the housing 11. The second space 222 is the area between the left side of the second support plate 17 and the housing 11. The heat dissipation vents 151 at the top and bottom of the housing 11 form air convection, allowing the heat sink 15 to dissipate heat quickly.

[0041] Preferably, it also includes a deep atomizing plate 51, a light atomizing plate 52, and a third motor 53 disposed on the third support plate 18. The third motor 53 is movably connected to the deep atomizing plate 51 and the light atomizing plate 52 by a third transmission mechanism 54, which controls the third motor 53 to drive the deep atomizing plate 51 and the light atomizing plate 52 to rotate through the third transmission mechanism 54, forming a first working state using the deep atomizing plate 51 and a second working state using the light atomizing plate 52. The deep atomizing plate 51 and the light atomizing plate 52 are components used for stage lighting and have different atomization effects. The third transmission mechanism 54 is a fan-shaped disk connected to the shaft of the third motor 53. The deep atomizing plate 51 and the light atomizing plate 52 are located on different rotation radii of the fan-shaped disk and do not overlap with each other. The touch screen 4 and the third motor 53 are located in the same circuit. The operator controls the operation of the third motor 53 through the touch screen 4, which drives the third transmission mechanism 54 to rotate, thereby switching the illumination position of the light source 12 back and forth between the deep atomizing plate 51 and the light atomizing plate 52, thus switching different soft light effects.

[0042] Preferably, a first limiting post 181 is fixedly provided on the third support plate 18. The first limiting post 181 is located on the rotation path of the third transmission mechanism 54 and is used to constrain the rotation angle of the deep atomizing plate 51 and the light atomizing plate 52. The first limiting post 181 is located on the rotation path of the sector disk and is used to limit the angle of the sector disk to prevent excessive rotation from interfering with other internal parts, which could lead to transmission failure and damage to parts, thus ensuring safe operation.

[0043] Preferably, the device further includes a filter 6 located at least partially within the housing 11. A slot 182 for accommodating the filter 6 is fixedly provided on the third support plate 18. The slot 182 extends through to the top of the housing 11, forming an insertion port 112. A second limiting post 183 is fixedly provided on the third support plate 18. The second limiting post 183 is located at the end of the slot 182 and is used to constrain the displacement path of the filter 6 along the slot 182. The filter 6 is a CRI enhancement filter used to correct color rendering defects of the light source 12, making the colors under the light more natural and realistic. The slot 182 is configured to be vertically continuous, and the second limiting post 183 is located below the slot 182 and abuts against the filter 6. Installation and removal can be completed by inserting and removing the filter 6, making operation convenient.

[0044] Preferably, a gripping part 7 is movably provided at the bottom of the housing 11. The gripping part 7 has an active state that is displaced relative to the housing 11, and a locked state that is fixed to the housing 11. When the first motor 21 and the second motor 31 rotate in both directions, causing the worm gear to rotate and push the reflector 13 and zoom lens 14 forward and backward, the center of gravity of the entire follow spot will shift. When the gripping part 7 is in the active state, it moves in the direction of the center of gravity shift, changing the fulcrum of the grip, thereby achieving a more effortless gripping effect. When the optimal effort-saving position is reached, the gripping part 7 is locked and fixed to the housing 11 to prevent slippage, making operation simple and effortless.

[0045] Preferably, the gripping part 7 includes a movable plate 71 that abuts against the housing 11. A bolt 114 is fixedly installed at the bottom of the housing 11, and a knob 712 is provided below the movable plate 71. The knob 712 and the bolt 114 together form a locked state and a movable state of the movable plate 71 relative to the housing 11. The movable plate 71 is movably connected to the housing 11. When the knob 712 and the bolt 114 are tightened, the movable plate 71 is pressed against the bottom of the housing 11, and at this time the movable plate 71 and the housing 11 are fixed to each other, forming the locked state. When the knob 712 and the bolt 114 are loosened, the movable plate 71 returns to the movably connected state with the housing 11. At this time, the movable plate 71 can slide at the bottom of the housing 11, forming the movable state, which is simple and labor-saving to operate.

[0046] Preferably, a third limiting post 113 is fixedly provided at the bottom of the housing 11, and a groove 711 is provided on the movable plate 71 to accommodate the third limiting post 113. The groove 711 and the third limiting post 113 together form a path that constrains the displacement of the movable plate 71 along the groove 711. An annular protrusion 115 is provided circumferentially on the side wall of the third limiting part. The diameter of the annular protrusion 115 is larger than the diameter of the groove 711. The groove 711 is opened along the axis of the follow spot. The third limiting post 113 holds the movable plate 71 between the top of the annular protrusion 115 and the bottom of the housing 11. When the knob 712 and the bolt 114 are loosened, the movable plate 71 returns to the movable connection state with the housing 11. At this time, the movable plate 71 slides above the annular protrusion 115 through the groove 711. The direction of sliding is the opening direction of the groove 711, which prevents the grip 7 from falling out of the housing 11 during the sliding process and ensures that the sliding operation is more stable and safe.

[0047] Preferably, a fourth support plate 19 is also vertically disposed on the first support plate 16. The fourth support plate 19 is located to the right of the third support plate 18. The first support plate 16, the third support plate 18 and the fourth support plate 19 together define a third space 333 for accommodating the zoom lens 14. The first support plate 16 and the fourth support plate 19 together define a fourth space 444 for accommodating the reflector 13. The third support plate 18 and the fourth support plate 19 together form a path that constrains the zoom lens 14 to move along the axial direction of the follow spot lamp. The fourth support plate 19 forms a path that constrains the reflector 13 to move along the axial direction of the follow spot lamp. The fourth support plate 19 is vertically fixed to the housing 11. The third space 333 is the area enclosed by the first support plate 16, the third support plate 18, the fourth support plate 19, and the housing 11. The fourth space 444 is the area enclosed by the right side of the first support plate 16, the fourth support plate 19, and the housing 11. The zoom lens 14 slides within the third space 333. The worm gear of the second transmission mechanism 32 is arranged along the axis of the follow spot lamp. The zoom lens 14 is displaced along the axis of the follow spot lamp under the drive of the worm gear transmission structure. The third support plate 18 and the fourth support plate 19 are located at the beginning and end of the axial displacement path of the zoom lens 14, forming a barrier. The reflector 13 slides within the fourth space 444. The worm gear of the first transmission mechanism 22 is arranged along the axis of the follow spot lamp. The reflector 13 is displaced along the axis of the follow spot lamp under the drive of the worm gear transmission structure. The fourth support plate 19 is located at the beginning of the axial displacement path of the reflector 13, forming a barrier to prevent mutual interference. The layout is reasonable.
