Description

Technical Field

[0001] The invention relates to the field of video recording and video production, in particular to a light adjustment mechanism for fill light of a recorder. Background Art

[0002] In today's era of booming digital media, video recording occupies an extremely important position in many fields. As the core equipment of video recording, the quality of the video recorded by the recorder is directly affected by the lighting conditions. In many video recording scenes, natural light or existing lighting may not provide sufficient brightness, resulting in the dark picture captured by the recorder and the details of the subject are difficult to see. Therefore, fill light is needed to increase the overall brightness, so that the facial expressions of the people being photographed, the appearance of the product and other details can be clearly presented, thereby improving the quality of the recorded picture.

[0003] Existing video recorder fill-in lighting equipment usually includes single-lamp fill-in lighting and dual-lamp fill-in lighting. The dual-lamp fill-in lighting is symmetrically distributed on both sides of the video recorder, which can provide more uniform lighting and reduce shadows. However, many lighting ranges are fixed. For example, some simple fill-in lights have a lampshade and a lamp body that are designed as one piece, and the divergence of the light source cannot be changed. When it is necessary to shoot close-up shots, this fixed-range lighting may cause the area around the subject to be illuminated, distracting the audience's attention from the subject. When shooting a panoramic shot, the fixed small-range lighting cannot meet the need to illuminate the entire scene, and the lighting area cannot be accurately adjusted. The existing solution is to manually adjust the relative positions of the dual-lamp fill-in lighting, and then Then adjust the angle position of the fill light so that the lighting range can meet the needs of different scenes, but the adjustment is cumbersome, which reduces the adjustment efficiency. Secondly, in the horizontal adjustment process of the existing dual-lamp fill light, it is necessary to manually adjust the dual-lamp fill light on both sides symmetrically around the subject, but it takes a lot of time to manually adjust the horizontal position of the dual-lamp fill light, especially when the shooting scene changes frequently or the fill light position accuracy is required to be high. Each adjustment requires the operator to manually move the lamp and repeatedly compare whether the positions of the lamps on both sides are symmetrical. Therefore, it is difficult to ensure that the fill lights on both sides are completely symmetrical around the subject in the horizontal direction, resulting in the inability to accurately present the details and texture of the subject.

[0004] Therefore, it is necessary to propose a light adjustment mechanism for fill light of a recorder to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 4As shown, a light adjustment mechanism for fill light of a recorder includes a base 1, a lifting rod 11 is arranged on one side of the top of the base 1, and an adjustment seat 12 with a locking buckle is arranged in the middle of the lifting rod 11. The lifting rod 11 can change the vertical height position of the illumination lamp 13 to meet the requirements of shooting objects or scenes at different heights. The joint seat 12 can be fixed at different heights on the lifting rod 11 through the locking buckle, and the illumination lamps 13 are arranged on the left and right ends of the adjustment seat 12. A recording stand 14 is arranged on the other side of the top of the base 1 and opposite to the lifting rod 11, for placing recording equipment. The illumination adjustment component 2 is arranged on the adjustment seat 12, and is used to drive the two illumination lamps 13 to move horizontally relative to each other, and at the same time drive the two illumination lamps 13 to rotate vertically at different angles. The illumination adjustment component 2 includes: a linkage block 21, which is provided with two and symmetrically distributed on the left and right sides of the adjustment seat 12. The linkage block 21 is an elongated block, and a T-shaped slide groove is provided inside the linkage block 21; a threaded rod 22, which is provided with two and symmetrically rotated in the slide groove of the linkage block 21, and the thread directions are opposite; a slider 23, which is provided with two and has a T-shaped structure. The two sliders 23 are both slidably connected in the slide groove and are screwed to the end of the threaded rod 22 away from the adjustment seat 12 The light frames 24 are connected in two pieces and are symmetrically distributed at the front end of the linkage block 21. The light frames 24 are U-shaped. The light lamp 13 is arranged on the inner side of the light frames 24. One side of the slider 23 is fixedly connected to the rear end of the light frames 24. The linkage gears 25 are provided in two pieces and are rotatably connected to the rear end of the light frames 24. The rack plates 26 are provided in two pieces and are installed under the linkage block 21. The linkage gears 25 and the rack plates 26 are meshed with each other. The limit plates 27 are grouped in two pieces. One group of limit plates 27 is installed at the rear end of the light frames 24. One group of limit plates 27 is connected to the inner side of the linkage block 21 by means of a slide rail.

[0022] It should be noted that the illumination lamp 13 rotates horizontally: when the threaded rod 22 rotates, the slider 23 moves linearly along the axial direction of the threaded rod 22 in the slide groove, and the slider 23 drives the illumination frame 24 to move relatively close to or away from it. At the same time, a set of limit plates 27 at the rear end of the illumination frame 24 is connected to the inner side of the linkage block 21 by means of a slide rail, which guides and stabilizes the movement of the illumination frame 24, ensuring the stability and accuracy of the movement. The illumination lamp 13 rotates vertically: when the illumination frame 24 moves horizontally relative to the slider 23, the linkage gear 25 rolls along the rack plate 26, thereby realizing the self-rotation of the linkage gear 25. The self-rotation of the linkage gear 25 can drive the illumination lamp 13 to rotate vertically; Specifically, in the initial stage, the two lighting racks 24 are located at the end of the threaded rod 22 away from the adjustment seat 12, and are arranged in an inclined manner toward the base 1. When it is necessary to adjust the lighting to adapt to the photographed object, the threaded rod 22 is driven to rotate, so that the slider 23 moves along the slide groove toward the direction close to the adjustment seat 12. During the horizontal approach of the lighting racks 24 on both sides, the linkage gear 25 will rotate counterclockwise along the rack plate 26, thereby driving the lighting lamp 13 to rotate vertically around the photographed object. The lighting direction of the lighting lamp 13 originally arranged in an inclined manner toward the base 1 gradually changes, and is gradually adjusted from a relatively diffuse state to a state of gathering on the base 1, that is, the lighting angle gradually concentrates on the area where the photographed object is located. The lighting rack 24 and the lighting lamp 13 are driven by the threaded rod 22 to approach the photographed object, and during the horizontal approach process, the linkage gear 25 cooperates with the rack plate 26 to realize the vertical rotation of the lighting lamp 13, which can accurately position the lighting on the photographed object, and can make the light accurately cover the required area, avoid wasting light in unnecessary places, and improve the effectiveness of fill light.

[0023] like Figure 2 , Figure 5 and Figure 6 As shown, a linkage slot is provided on the inner side of the adjustment seat 12, and a linkage assembly 211 is arranged in the inner cavity of the adjustment seat 12, and is used for the rotation of the recording frame 14 to drive the two illumination lamps 13 to move relative to each other. The linkage assembly 211 includes: a first bevel gear 212, which is rotatably connected to the bottom wall of the linkage slot; a second bevel gear 213, of which there are two, and the two second bevel gears 213 are symmetrically rotatably connected to the left and right sides of the linkage slot, and the two second bevel gears 213 are meshed with the first bevel gear 212; a limiting strip block 214, which is rotatably connected to the bottom of the adjustment seat 12, and is fixedly connected to the bottom of the first bevel gear 212 through a connecting rod, and its cross section is hexagonal, which plays a role in transmitting torque, and transmits the power from the linkage driving wheel 217 and the limiting sleeve block 216 to the first bevel gear 212, so as to ensure the accuracy and Stability, fixed block 215, which is fixedly installed at the bottom of the lifting rod 11; the limiting sleeve block 216, which is rotatably connected to the side of the fixed block 215 away from the lifting rod 11, and the lower part of the limiting strip block 214 is slidably connected to the upper inner side of the limiting sleeve block 216; the linkage driving wheel 217, which is rotatably connected to the lower part of the fixed block 215, and the upper part is fixedly connected to the limiting sleeve block 216 through a connecting rod; the fixed gear 218, which is fixedly connected to the upper middle part of the base 1 for storing the filming products; the turntable 219, which is hollow, the turntable 219 is rotatably connected to the upper part of the base 1, and is located on the outer side of the fixed gear 218, and the lower part of the lifting rod 11 is installed on the rear end of the turntable 219; the connecting base plate 2191, which is installed at the front end of the turntable 219, and the end of the connecting base plate 2191 away from the turntable 219 is fixedly connected to the recording frame 14.

[0024] It should be noted that when the operator drives the recording stand 14 to rotate, the turntable 219 is driven to rotate on the base 1 through the connection base plate 2191. The rotation of the turntable 219 will cause the linkage drive wheel 217 to rotate on the fixed gear 218. The rotation of the linkage drive wheel 217 drives the limit sleeve block 216 to rotate through the connecting rod. Since the limit sleeve block 216 and the limit strip block 214 are in a limit sliding connection, the rotation of the limit sleeve block 216 will drive the limit strip block 214 to rotate. The rotation of the limit strip block 214 will then drive the first bevel gear 212 to rotate. At the same time, the first bevel gear The rotation of 212 will drive the second bevel gears 213 on both sides to rotate, and finally the second bevel gears 213 will drive the threaded rod 22 connected thereto to rotate, thereby realizing the relative movement of the two lighting lamps 13. As before, through the cooperation of the threaded rod 22 and the slider 23 and other components, the lighting frame 24 can drive the lighting lamp 13 to move toward or away horizontally and rotate vertically. The rotation of the recording frame 14 can indirectly drive the adjustment of the lighting lamp 13, so that the operator can conveniently adjust the lighting while operating the recording equipment, which greatly improves the convenience of operation and shooting efficiency.

[0025] like Figure 2 As shown, a semi-arc-shaped arc groove 2192 is provided at the top of the base 1 and on the right side of the turntable 219, and a torsion rod 2193 is threadedly connected to the bottom plate 2191 on one side of the arc groove 2192, and the fixation of the turntable 219 is controlled by squeezing the arc groove 2192 by the torsion rod 2193.

[0026] It should be noted that when the turntable 219 needs to be fixed, the operator rotates the torsion bar 2193 that is threadedly connected to the connecting bottom plate 2191, and it moves along the thread straight line close to the arc groove 2192 and squeezes to generate friction. If the friction is large enough, the turntable 219 is prevented from rotating relative to the base 1. When releasing the fixation, the torsion bar 2193 is rotated in the opposite direction to move it away from the arc groove 2192 to reduce the friction, and the turntable 219 can rotate freely. This method can fix or release the turntable 219 through a simple squeezing operation, without the need for complex locking devices or tools. The operator can quickly fix the recording frame 14 when it needs to be fixed (i.e., the position of the turntable 219), and quickly release the fixation when adjusting the recording angle, effectively improving the operational flexibility and efficiency of the recording equipment.

[0027] like Figure 3 and Figure 7As shown, a limit rod 251 slidably connected to the lighting lamp 13 is rotatably connected at the bottom of the lighting frame 24, and a movable plate 252 slidably connected to the limit rod 251 is installed at the front end of the lighting lamp 13. An arc-shaped limit bar 254 with a semi-arc shape is provided on the inner side of the lighting frame 24. The longitudinal section of the arc-shaped limit bar 254 is a concave structure. The outer edge of the movable plate 252 extends out and is slidably connected to the concave inner side of the arc-shaped limit bar 254. An arc-shaped opening is opened at the front end of the arc-shaped limit bar 254, and a limit slider 253 slidably connected in the opening is installed on the top of the movable plate 252.

[0028] During the operation of the light adjustment assembly 2, when the light lamp 13 is driven to perform horizontal relative motion, the linkage gear 25 will rotate due to the meshing with the rack plate 26. Since the lower portion of the light frame 24 is rotatably connected to a limit rod 251 that is slidably connected to the light lamp 13, and the linkage gear 25 drives the limit rod 251 to rotate synchronously, under the action of the limit rod 251 and the light lamp 13, the light lamp 13 can rotate vertically around the photographed object. At the same time, the front end of the light lamp 13 The movable disk 252 cooperates with the arc-shaped limit strip 254 on the inner side of the illumination frame 24. When the illumination lamp 13 rotates, the movable disk 252 rotates accordingly. The sliding of the limit slider 253 in the opening limits and restricts the vertical rotation of the illumination lamp 13, thereby determining the vertical rotation range of the illumination lamp 13. Through the sliding connection between the limit rod 251 and the illumination lamp 13 and the cooperation between the movable disk 252 and the arc-shaped limit strip 254, the vertical rotation angle of the illumination lamp 13 can be accurately controlled.

[0029] like Figure 8-Figure 10 As shown, the symmetrical adjustment component 3 is arranged on the adjustment seat 12, and is used to adjust the two lighting lamps 13 to rotate horizontally at different angles along one side of the axis of the base 1. The symmetrical adjustment component 3 includes: a support frame 31, which is provided in two numbers and is installed above the adjustment seat 12; a worm 32, which is rotatably connected between the two support frames 31, and the support frame 31 located at the front end is rotatably connected to a handle fixedly connected to the worm 32; a bearing plate 33, which is provided in two numbers and is symmetrically installed at the left and right ends of the adjustment seat 12; a worm wheel 34, which is provided in two numbers, And it is symmetrically rotatably connected above the bearing plate 33; there are two rotating plates 35, which are symmetrically installed on the side of the linkage block 21 close to the adjustment seat 12. The rotating plate 35 is rotatably connected below the bearing plate 33, and the top of the rotating plate 35 is fixedly connected to the worm gear 34 through a connecting rod; the universal joint 36, one end of which is close to the adjustment seat 12, rotates through the inner side of the adjustment seat 12 through the connecting rod and is fixedly connected to the second bevel gear 213, and the end of which is away from the adjustment seat 12, rotates through the inner side of the linkage block 21 through the connecting rod and is fixedly connected to one end of the threaded rod 22.

[0030] The operator turns the handle to rotate the worm 32 between the two support frames 31. The rotation of the worm 32 will drive the two worm wheels 34 to rotate. The rotation of the worm wheel 34 drives the rotating plate 35 to rotate through the connecting rod fixedly connected to the top thereof. The rotating plate 35 rotates around a specific axis under the bearing plate 33. The rotation of the rotating plate 35 will cause the linkage block 21 to rotate at an angle. The linkage block 21 and the adjustment seat 12 as well as the linkage block 21 and the threaded rod 22 are connected by a universal joint 36. When the linkage block 21 rotates at an angle, the universal joint 36 can bridge the spatial position difference caused by the angle change, and stably transmit the power of the second bevel gear 213 to the threaded rod 22, thereby driving the illumination lamp 13 to rotate horizontally at different angles along one side of the axis of the base 1 on both sides of the photographed object, so as to quickly and accurately adjust the horizontal rotation angle of the illumination lamp 13. Compared with the existing manual adjustment method, it greatly saves adjustment time, especially suitable for situations where the shooting scenes are frequently changed or the fill light position accuracy is required to be high. The operator only needs to turn the handle to make the two side lights 13 rotate horizontally synchronously and symmetrically according to the preset linkage relationship. There is no need to repeatedly move the lamps manually and compare the positions, which effectively improves work efficiency and adjustment accuracy.

[0031] It is worth noting that the meshing mode of the worm 32 and the worm wheel 34 makes them have better stability during the transmission process, and due to the self-locking characteristics of the worm 32 and the worm wheel 34, the lighting lamp 13 will not rotate accidentally, thereby maintaining the adjusted fill light position and improving the reliability of the equipment during use.

[0032] like Figure 8 As shown, a limiting arc cover 311 is installed at one end of the two bearing plates 33 away from the adjustment seat 12, a bending groove is opened in the limiting arc cover 311, an expansion spring rod 312 is installed in the bending groove, and a curved slider 313 slidably connected to the expansion spring rod 312 is installed above the rotating plate 35.

[0033] When the rotating plate 35 rotates, whether accelerating or decelerating, the elastic force of the expansion spring rod 312 can make its rotation more stable, reducing the vibration and shaking that may be caused by sudden starting or stopping. The elastic force provided by the expansion spring rod 312 plays a buffering and stabilizing role during the rotation of the rotating plate 35.

[0034] like Figure 3 and Figure 7 As shown, a cross-shaped groove 241 is provided at the front end of the illumination frame 24, a cross-shaped block 242 is slidably connected inside the front end of the cross-shaped groove 241, the top of the cross-shaped block 242 extends out of the top of the illumination frame 24 and is installed with an L-shaped block 243, the bottom of the cross-shaped block 242 extends out of the outside of the illumination frame 24 and is fixedly connected to the top of the arc-shaped limit strip 254, and symmetrically distributed magnetic strips 244 are installed on the top of the illumination frame 24, and the L-shaped block 243 and the magnetic strip 244 attract each other.

[0035] When the operator holds the L-shaped blocks 243 on both sides with both hands, and the L-shaped blocks 243 drive the cross-shaped blocks 242 to slide along the inner side of the cross-shaped groove 241, the cross-shaped blocks 242 will drive the connected L-shaped blocks 243 and the arc-shaped limit strips 254 to move synchronously. When the arc-shaped limit strips 254 move synchronously with the sliding of the cross-shaped blocks 242, the moving plate 252 will be prompted to move along the axial direction (front and back direction) of the limit rod 251, thereby driving the illumination lamp 13 to move forward and backward along the limit rod 251. In this way, by manually operating this series of components, the position adjustment of the illumination lamp 13 on the limit rod 251 is realized, so that the position can be changed in the front and back direction, so as to cooperate with the symmetrical adjustment component 3 to perform more comprehensive illumination adjustment; When the operator completes the sliding operation of the L-shaped block 243 and the cross-shaped block 242 and releases both hands, the attraction of the magnetic strip 244 to the L-shaped block 243 will take effect, stabilizing the L-shaped block 243 at the current position; The front and rear positions of the illumination lamp 13 on the limit rod 251 can be flexibly adjusted through manual operation, which adds a new dimension to the illumination adjustment. Combined with the horizontal rotation adjustment of the illumination lamp 13 by the symmetrical adjustment component 3, the illumination lamp 13 can be flexibly adjusted in two dimensions: horizontal rotation and front and rear movement, so as to more accurately adapt to different shooting scenes, the shape and position of the shooting object and other factors, and realize a more diversified and refined illumination layout to meet the best fill light effect under various shooting requirements.

[0036] like Figure 3 and Figure 7 As shown, a pointer 245 is installed on the side of the cross block 242 close to the axis of the base 1, and a scale 246 is installed below the side of the illumination frame 24 close to the axis of the base 1.

[0037] By using the scale indicated by the pointer 245 on the scale 246, the current front-to-back position of the lighting lamp 13 relative to the axis of the base 1 can be accurately known, so that when adjusting another lighting lamp 13, it can be used as a reference to move it to a position symmetrical to the first lighting lamp 13, ensuring that the layout of the two lighting lamps 13 in the front-to-back direction is more accurately symmetrical, thereby achieving a more uniform and coordinated fill light effect.

[0038] The working principle of the present invention is that the illumination adjustment mechanism for fill light of a recorder is used as follows: when the operator rotates the recording frame 14 and rotates along one side of the base 1, the turntable 219 is driven to rotate above the base 1 through the connecting bottom plate 2191. The rotation of the turntable 219 causes the linkage driving wheel 217 below it that cooperates with the fixed gear 218 to rotate. After the linkage driving wheel 217 rotates, it drives the upper fixedly connected limiting sleeve block 216 to rotate through the connecting rod. Since the limiting sleeve block 216 and the limiting strip block 214 are limitedly slidably connected, the rotation of the limiting sleeve block 216 will drive the limiting strip block 214 to rotate together. The limiting strip block 214 drives the first bevel gear 212 to rotate through the connecting rod. At the same time, the rotation of the first bevel gear 212 drives the second bevel gears on both sides to rotate. The second bevel gear 213 rotates synchronously. Since each second bevel gear 213 is connected to one end of the threaded rod 22 in the light adjustment assembly 2 through a universal joint 36, the rotation of the second bevel gear 213 will drive the threaded rod 22 to rotate. When the threaded rod 22 rotates, the T-shaped slider 23 is threadedly connected to the end of the threaded rod 22 away from the adjustment seat 12 and slides in the T-shaped slide groove of the linkage block 21. The slider 23 moves linearly along the axial direction of the threaded rod 22. The movement of the slider 23 drives the illumination frame 24 to move relatively closer or farther away, so as to adjust the horizontal position of the illumination lamp 13, thereby changing the illumination coverage and intensity distribution. At the same time, during the horizontal movement of the illumination frame 24, the linkage gear 25 at its rear end rolls and rotates along the rack plate 26, so that the illumination lamp 13 rotates vertically around the photographed object. The operator rotates the turning handle fixedly connected to the worm 32 on the front support frame 31 of the symmetrical adjustment component 3. The turning of the turning handle drives the worm 32 to rotate between the two support frames 31. Since the worm 32 is meshed with the two worm wheels 34 above the bearing plate 33, the rotation of the worm 32 causes the two worm wheels 34 to rotate synchronously. The rotation of the worm wheel 34 drives the rotating plate 35 to rotate through the connecting rod. The rotating plate 35 is symmetrically mounted on the side of the linkage block 21 close to the adjustment seat 12 and rotates around a specific axis below the bearing plate 33. Its rotation will cause the linkage block 21 to produce an angular rotation, thereby driving the lighting lamp 13 to rotate horizontally at different angles on both sides of the photographed object along one side of the axis of the base 1. The horizontal rotation angle of the lighting lamp 13 can be quickly and accurately adjusted to meet the needs of different scenes.
