Description

Technical Field

[0001] The present invention relates to the technical field of photographic equipment, and in particular to an intelligent movie photography light box. Background Art

[0002] In the complex scenes of film shooting, photography light boxes are one of the indispensable equipment for the crew to achieve the ideal lighting effects. Usually, the photography light boxes used by the crew are mainly composed of basic light source components to provide lighting, lampshades to adjust the light to a certain extent, such as gathering, diffusing or softening, and a relatively simple support bracket to fix the position and height of the entire light box.

[0003] However, with the continuous development of film shooting technology and the increasing requirements for picture quality and shooting efficiency, traditional photography light boxes have exposed obvious limitations. In terms of the rotation and adjustment function of the light box, traditional light boxes often only have a relatively single rotation method, generally through simple manual joint adjustment, not only the rotation range is limited, it is difficult to achieve all-round and multi-angle flexible fill light, but also the operation is not convenient and smooth during the rotation process, and it is unable to quickly respond to the frequently changing light angle requirements during the shooting process. For example, when shooting an exciting action scene, it is necessary to quickly adjust the light box angle to follow the actor's movements and position changes. The rotation design of the traditional light box seems to be unable to do so, and it is unable to provide accurate light coordination in time, affecting the shooting effect and progress.

[0004] Under the high-intensity use of film shooting, the large amount of heat generated by the long-term emission of the light source cannot be dissipated in time, which will not only accelerate the aging and damage of the light source, reduce its luminous performance and service life, but also may cause the instability of the light color, resulting in color deviation in the shooting picture. At the same time, due to the lack of a special cleaning design, dust can easily enter the interior through the gap between the lampshade and the light box, accumulate on the surface of the light source and the lampshade, and reduce the transmission efficiency and quality of the light. Moreover, to clean and maintain the traditional light box, it is often necessary to disassemble multiple parts, and the operation is complicated and cumbersome, which is very inconvenient on the busy film shooting site and will take up a lot of valuable shooting time and labor costs.

[0045] In order to make the purpose, technical scheme and advantages of the embodiment of the present invention clearer, the technical scheme of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention. The schematic implementation mode of the present invention and its description are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual research and development stage.

[0046] Unless otherwise defined, the technical terms or scientific terms used in the present invention shall have the usual meanings understood by persons with ordinary skills in the field to which the present invention belongs.

The words "include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0047] With the advancement of film shooting technology, the requirements for picture quality and efficiency are getting higher and higher, and the limitations of traditional photography light boxes are highlighted. In terms of rotation, it has a single method, relying on manual joints, with a narrow range and inconvenient operation, which is difficult to meet the needs of fast light change during shooting, such as the inability to accurately fill in the light in time during action scenes. During use, the heat is difficult to dissipate, which accelerates the aging and damage of the light source, and the unstable light color causes color deviation in the picture. In addition, there is no cleaning design, dust is easy to enter, and cleaning requires disassembling multiple parts, which is cumbersome and inconvenient, taking up shooting time and labor costs.

[0048] Embodiment 1:

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, the present embodiment provides an intelligent movie photography light box, comprising a light source box 10 and a light source 11 arranged on the light source box 10, a frame 21 surrounding the light source 11 is arranged on one side of the light source box 10 where the light source 11 is arranged, a lampshade 20 is arranged between adjacent frames 21, a tripod 22 for supporting the photography light box is arranged below the light source box 10, a bearing platform 30 is arranged below the light source box 10 in the vertical direction, a ring-shaped protrusion 31 is arranged on the bearing platform 30, a ring-shaped opening matching the protrusion 31 is arranged on the light source box 10, and the protrusion 31 and the ring-shaped opening can enable the light source box 10 to rotate on the bearing platform 30; a rotating mechanism capable of driving the light source box 10 to rotate is arranged inside the bearing platform 30; a heat dissipation mechanism is arranged inside the light source box 10, and the heat dissipation mechanism is triggered when the rotating mechanism works to disturb the airflow inside the light source box 10; the intelligent movie photography light box is also provided with a stabilizing mechanism, which is arranged between the light source box 10 and the tripod 22, and is used to adjust the overall center of gravity of the intelligent movie photography light box and enhance the stability of the tripod 22 when the light source box 10 is rotated.

[0050] In filming, in order to solve the problems of inconvenient rotation, poor heat dissipation and poor stability of traditional photography light boxes, this solution uses a support platform 30 as a key component. The internal rotating mechanism meshes with the first bevel gear 12 on the light source box 10 through the bevel gear 32 to achieve flexible rotation of the light source box 10. The operator turns the handle 351, and the bevel gear 32 is driven to rotate through the connecting rod 33, so that the light source box 10 can quickly and accurately change the direction of light to meet the needs of different shooting angles. At the same time, the rotating shaft 34 drives the blades 63 on the rotating rod 60 to rotate with the help of the transmission belt 342, and the airflow generated is disturbed in the light source box 10, effectively taking away heat and removing dust, ensuring that the light source 11 emits light stably and prolongs its service life. Furthermore, the second bevel gear 40 in the stabilizing mechanism cooperates with the bevel gear 32, so that the moving rod 50 drives the stabilizing rod 70 and the clamping mechanism to move. When the light box rotates, the center of gravity is adjusted according to the situation and the legs of the tripod 22 are clamped, which enhances the overall stability, prevents tipping, ensures smooth shooting, and comprehensively improves the performance and shooting efficiency of the photography light box.

[0051] like Figure 3 and Figure 4 , a through hole 13 is provided on the light source box 10; the rotating mechanism includes a first bevel gear 12 and a bevel gear 32, the first bevel gear 12 is provided on the light source box 10, and an opening 121 coincident with the axis of the through hole 13 is provided on the first bevel gear 12; the bevel gear 32 is provided inside the carrier 30 and matches with the first bevel gear 12, one end of the bevel gear 32 is provided with a connecting rod 33 passing through the carrier 30, and the other end of the bevel gear 32 is connected to a hollow structured rotating shaft 34, and a fixing rod 36 penetrating into the interior of the rotating shaft 34 is provided on the inner wall of the carrier 30; when the bevel gear 32 rotates, it can drive the light source box 10 to rotate through the first bevel gear 12.

[0052] The first bevel gear 12 is firmly mounted on the light source box 10 by a specific mounting method, and its opening 121 is precisely aligned with the perforation 13 of the light source box 10, ensuring the stability and accuracy of the subsequent transmission. The bevel gear 32 is mounted inside the support platform 30 and is tightly meshed with the first bevel gear 12. This gear transmission method can efficiently transmit power to the light source box 10 and achieve stable rotation. One end of the connecting rod 33 is firmly connected to the bevel gear 32, and the other end is connected to the turntable 35 on which a handle 351 is movably mounted. The operator drives the connecting rod 33 and the bevel gear 32 to rotate by turning the handle 351, and then drives the light source box 10 to rotate, thereby meeting the need for rapid adjustment of different lighting angles during shooting. For example, when shooting a scene of dialogue between characters, the light direction can be quickly adjusted according to the position and expression changes of the actors, thereby enhancing the three-dimensional sense and expressiveness of the picture.

[0053] A further optimization scheme is that the heat dissipation mechanism includes a rotating rod 60, a first pulley 341 and a second pulley 61, one end of the rotating rod 60 is rotatably connected to the inner wall of the light source box 10, and the other end of the rotating rod 60 is rotatably connected to the inner wall on the opposite side of the light source box 10; a fixed shaft 62 is sleeved on the rotating rod 60, and a plurality of blades 63 are provided on the fixed shaft 62; a second pulley 61 is also provided on the rotating rod 60, and a first pulley 341 and a transmission belt 342 are provided on the rotating shaft 34, and the transmission belt 342 passes through the opening 121 and the through hole 13 to connect the first pulley 341 with the second pulley 61; when the rotating shaft 34 rotates, the rotating rod 60 drives the blades 63 to rotate to generate airflow to dissipate heat and remove dust from the light source box 10.

[0054] The two ends of the rotating rod 60 are flexibly connected to the inner walls of the two opposite sides of the light source box 10 by means of bearings, etc., to ensure smooth rotation. The multiple blades 63 on the fixed shaft 62 have suitable shapes and angles to ensure that sufficient and uniform airflow can be generated during rotation. When the rotating shaft 34 of the rotating mechanism rotates, the power is transmitted to the second pulley 61 on the rotating rod 60 through the transmission belt 342 (made of rubber material, with good flexibility and friction, ensuring the reliability of transmission), driving the rotating rod 60 to rotate at high speed, and the blades 63 rotate rapidly therewith, and the generated airflow forms an effective disturbance inside the light source box 10. On the one hand, it can take away a large amount of heat generated by the light source 11 in time to avoid the performance degradation and shortened life of the light source 11 due to overheating. On the other hand, it can blow out the dust accumulated inside the light source box 10, keep the interior clean, maintain a stable light output quality, and reduce the shooting interruption and repeated shooting times caused by light problems.

[0055] like Figure 3 , Figure 5 and Figure 6, a circular hole is provided on the carrier 30; the stabilizing mechanism includes a second bevel gear 40 and a moving rod 50, the second bevel gear 40 is arranged inside the carrier 30 and matches with the bevel gear 32, the second bevel gear 40 is provided with a rotating cylinder 42 coaxial with the second bevel gear 40, and a through hole 41 penetrating the second bevel gear 40 is provided at the center of the second bevel gear 40; the rotating cylinder 42 matches with the circular hole so that the second bevel gear 40 can rotate around the center of the circular hole; an internal thread section 52 is provided on the inner wall of the rotating cylinder 42, and an external thread section 51 matching with the internal thread section 52 is provided on the outer wall of the moving rod 50; when the bevel gear 32 drives When the second bevel gear 40 rotates, the moving rod 50 can be moved along the axial direction of the rotating drum 42 by matching the internal thread section 52 with the external thread section 51; the tripod 22 is composed of three legs, and three stabilizing rods 70 are provided at one end of the moving rod 50 away from the supporting platform 30, each stabilizing rod 70 is respectively sleeved on the corresponding leg, and the intersection of the axes of the three stabilizing rods 70 intersects with the axis of the moving rod 50 at one point; each stabilizing rod 70 is provided with a clamping mechanism for clamping the legs; in the vertical direction, when the moving rod 50 moves downward, the overall center of gravity is lowered and the stability of the tripod 22 is enhanced by the clamping mechanism.

[0056] During the shooting process, especially when the light source box 10 rotates, the center of gravity of the light box will change, causing the entire device to lose balance and fall over, damaging expensive photographic equipment. When the bevel gear 32 rotates to drive the second bevel gear 40 to rotate, the internal thread section 52 on the inner wall of the rotating drum 42 cooperates with the external thread section 51 on the outer wall of the moving rod 50, so that the moving rod 50 moves along the axis of the rotating drum 42. When the moving rod 50 moves downward, the rounded corners at its end contact the wedge-shaped surface 741 of the clamping block 74 in the upper chamber of the stabilizing rod 70, pushing the clamping block 74 to move in the direction close to the stabilizing block 73, overcoming the elastic force of the second spring 75, and at the same time, the stabilizing block 73 also generates a clamping force on the legs under the action of the first spring 72, thereby clamping the legs of the tripod 22, thereby lowering the center of gravity and enhancing stability.

[0057] like Figure 1 and Figure 7The stabilizing rod 70 is provided with a slot 71 for the supporting leg to pass through and a chamber connected to the slot 71; the clamping mechanism includes a clamping block 74 and a second spring 75 arranged in the chamber, the clamping block 74 is provided with a wedge-shaped surface 741 at one end close to the moving rod 50, the second spring 75 is arranged between the end of the moving rod 50 close to the chamber and the inner wall of the chamber, one end of the second spring 75 is movably connected to the end of the moving rod 50, and the other end of the second spring 75 is connected to the inner wall of the chamber; a first spring 72 and a stabilizing block 73 are also provided in the slot 71, one end of the first spring 72 is connected to the inner wall of the slot 71, and the other end of the first spring 72 is connected to the stabilizing block 73; in the vertical direction, when the moving rod 50 moves downward, the clamping block 74 is moved toward the direction close to the stabilizing block 73 by squeezing the wedge-shaped surface 741, thereby clamping the supporting leg.

[0058] The slot 71 on the stabilizing rod 70 provides installation space for the legs. The clamping block 74 in the chamber is provided with a wedge-shaped surface 741 at one end close to the moving rod 50. When the moving rod 50 moves downward, its end (provided with a rounded corner matching the wedge-shaped surface 741 to facilitate better contact and push the wedge-shaped surface 741) squeezes the wedge-shaped surface 741 of the clamping block 74, so that the clamping block 74 overcomes the elastic force of the second spring 75 and moves toward the stabilizing block 73. At the same time, the stabilizing block 73 also generates a certain clamping force on the legs under the action of the first spring 72. Through this double clamping action, the legs of the tripod 22 can be firmly clamped, effectively enhancing the stability of the tripod 22. During shooting, even if the center of gravity of the light box changes due to rotation, or it is used on an uneven ground, it can prevent the light box from tipping over.

[0059] like Figure 1 and Figure 2 One end of the connecting rod 33 is connected to the bevel gear 32 , and the other end of the connecting rod 33 is connected to a turntable 35 coaxial with the connecting rod 33 , and a handle 351 is movably connected to the turntable 35 .

[0060] One end of the connecting rod 33 is firmly connected to the bevel gear 32 to ensure reliable transmission of power, and the turntable 35 connected to the other end is movably connected to the handle 351, so that the operator can easily and flexibly apply force when turning the handle 351, and the existence of the turntable 35 can increase the force arm, so that the operator can drive the bevel gear 32 to rotate more effortlessly, thereby driving the light source box 10 to rotate. For example, when the light box angle needs to be frequently and quickly adjusted at the shooting site, the operator can conveniently operate the handle 351 to quickly realize the multi-angle rotation of the light source box 10, meet the light requirements of different shooting angles, improve shooting efficiency, and make the shooting process smoother.

[0061] Operation process:

[0062] When using the photographic light box, the operator first holds the handle 351 on the turntable 35 connected to the connecting rod 33, and turns the handle 351 to drive the bevel gear 32 to rotate. Since the bevel gear 32 is meshed with the first bevel gear 12 in the support platform 30, the light source box 10 starts to rotate through the matching structure of the annular protrusion 31 on the support platform 30 and the annular opening, thereby achieving rapid and accurate angle adjustment to meet the light direction required for the shooting scene; at the same time, the rotating shaft 34 rotates with the bevel gear 32, and the blade 63 assembly on the rotating rod 60 is driven to rotate through the transmission belt 342, and the air generated by the rotation of the blade 63 The flow is disturbed in the light source box 10, taking away the heat generated by the light source 11 and removing dust, ensuring that the light source 11 emits light stably; and in the rotation process, the bevel gear 32 will also drive the second bevel gear 40 matched thereto to rotate, so that the moving rod 50 moves along the axial direction of the rotating cylinder 42, and the stabilizing rod 70 and the clamping mechanism at the lower end of the moving rod 50 clamp the legs of the tripod 22, automatically adjust the center of gravity according to the rotation of the light box and stabilize the tripod 22 to prevent the light box from tipping over due to changes in the center of gravity. The various mechanisms work together to provide stable, efficient, and high-quality lighting conditions for film shooting, ensuring that the shooting work proceeds smoothly.

[0063] Embodiment 2:

[0064] like Figure 3 and Figure 8 On the rotating rod 60, the blades 63 and the rotating shaft 34 located on the same side are combined into a heat dissipation component. Based on the length direction of the transmission belt 342, a plurality of heat dissipation components are provided on the rotating rod 60. The blades 63 in each heat dissipation component have a specific shape, size and angle, and the rotating shaft 34 provides a stable rotation support and power transmission basis for it. When the rotating mechanism drives the rotating shaft 34 to rotate, the heat dissipation components operate synchronously, and the multiple components work together to generate a stronger and more uniform airflow, which efficiently dissipates heat and removes dust from the inside of the light source box 10, ensuring that during the shooting process, no matter what the environment is, good light output can be maintained, and the quality of the shooting picture is protected from interference from heat and dust.

[0065] like Fig. 9 , the light source box 10 is provided with an opening 14 for allowing the heat dissipation airflow to enter the interior of the lampshade 20. The light source box 10 is provided with an opening 14 for allowing the heat dissipation airflow to enter the interior of the lampshade 20. The position, size and shape of this opening 14 match the airflow path generated by the heat dissipation mechanism, ensuring that the heat dissipation airflow generated from the interior of the light source box 10 can smoothly enter the interior of the lampshade 20. When shooting, the light source 11 in the lampshade 20 will generate a lot of heat and easily accumulate dust. Through this opening 14, the heat dissipation airflow can directly act on the interior of the lampshade 20, dissipate the heat of the light source 11 more effectively, and blow out the dust in the lampshade 20 at the same time, further improving the heat dissipation and cleaning effect of the entire light box.

[0066] In this embodiment, the material of the transmission belt 342 is rubber. During the long-term filming process, the light box may experience multiple rotations and heat dissipation operations. The rubber transmission belt 342 can withstand repeated stretching, bending and friction, and is not prone to breakage, wear or deformation, thereby ensuring the reliability and durability of the entire system.

[0067] Embodiment 3:

[0068] like Figure 7 The end of the moving rod 50 close to the clamping block 74 is provided with a chamfer that matches the wedge-shaped surface 741. The chamfer design at the end of the moving rod 50 further optimizes the contact mode with the wedge-shaped surface 741 of the clamping block 74, and when the moving rod 50 moves up and down, it can push the clamping block 74 to move more smoothly, reduce jamming and friction, improve the response speed and reliability of the clamping mechanism, and ensure that during the rotation of the light box, the stabilizing mechanism can play a role in a timely and effective manner to stabilize the posture of the light box.

[0069] The present invention also provides an intelligent control system, which is applied to the intelligent movie photography light box of the present invention. The control system of the intelligent photography light box mainly consists of the following parts:

[0070] Sensor module: The light sensors are distributed around the lampshade 20, and are used to detect parameters such as light intensity and color temperature in the shooting scene in real time, and convert the optical signals into electrical signals for transmission to the controller; the angle sensor is installed at the rotating connection between the light source box 10 and the supporting platform 30, accurately measures the rotation angle of the light source box 10, and feeds back to the controller; the temperature sensor is placed inside the light source box 10, close to the light source 11, monitors the temperature changes of the light source 11 when it is working, and sends an alarm signal to the controller when the temperature exceeds the set threshold.

[0071] Controller: Uses a high-performance microprocessor, such as Arduino or Raspberry Pi, to receive and process various signals from sensors, and sends control instructions to the actuator according to preset programs and algorithms to achieve intelligent control of the light box.

[0072] Actuator module: The motor drive circuit and the motor are connected to the connecting rod 33 of the bevel gear 32 of the rotating mechanism. According to the instructions of the controller, the rotation speed and direction of the motor are precisely controlled, thereby driving the light source box 10 to rotate to the specified angle to achieve precise light angle adjustment; the dimming circuit and components are connected to the light source 11. According to the information fed back by the light sensor, the controller automatically adjusts the brightness and color temperature of the light source 11 through the dimming circuit to adapt to the light requirements of different shooting scenes. For example, when shooting night scenes, the color temperature is automatically lowered and the brightness is increased to create a realistic night atmosphere; the cooling fan control circuit and fan, when the temperature sensor detects that the temperature in the light source box 10 is too high, the controller starts the cooling fan control circuit to accelerate the fan to enhance the heat dissipation effect, ensure the normal working temperature of the light source 11, and prevent overheating damage.

[0073] The working process is as follows:

[0074] During the filming process, the light sensor continuously monitors the light conditions of the shooting scene and transmits the data to the controller. The controller calculates the required brightness, color temperature and angle adjustment of the light source 11 according to the preset shooting scene mode (such as indoor, outdoor, daytime, night, etc.) or the user-defined light parameters. Then, the controller sends instructions to the motor drive circuit to drive the motor to rotate, driving the light source box 10 to adjust to the appropriate angle through the rotating mechanism; at the same time, the brightness and color temperature of the light source 11 are adjusted through the dimming circuit to match the light requirements of the shooting scene. In addition, the temperature sensor monitors the temperature inside the light source box 10 in real time. Once the temperature exceeds the safety threshold, the controller immediately starts the cooling fan to speed up the air flow, take away the heat, and ensure that the temperature inside the light source box 10 is stable within the normal range, thereby realizing the intelligent, efficient and stable operation of the photography light box, providing high-quality lighting effects for movie shooting, and improving shooting efficiency and picture quality.
