Description

Technical Field

[0001] This utility model relates to the field of video shooting auxiliary structure technology, specifically to a lighting device for video shooting. Background Technology

[0002] During video shooting, lighting conditions directly affect the image quality, and professional lighting equipment is one of the core pieces of equipment in film and television production.

[0003] In the existing technology, lighting devices have the following defects: harsh light and easy overexposure: existing fill lights mostly adopt a direct light emission design, the light intensity is concentrated and directly acts on the subject, which easily leads to local overexposure of the image (such as the blown-out highlights on the face of the person), while producing harsh shadows (such as the background and the shadow of the subject edge being separated), which destroys the overall texture of the image.

[0004] Limited functionality and poor expandability: Most devices only have basic light-emitting functions, and angle adjustment relies on manual disassembly or simple brackets. They cannot quickly switch between horizontal, tilt, and other multi-angle light effects. When switching between scenarios such as "portrait close-up - group photo" and "product front - side detail", it is necessary to replace the device or make repeated adjustments, which is inefficient.

[0005] Fixed lighting range with limited adaptability: The lighting range is determined by the light emission angle of the lamp itself, and cannot be adjusted according to the size of the subject being photographed (such as a single person's face or full body, small products or large scenes). This results in redundant lighting in small scenes and insufficient lighting in large scenes, limiting the applicable scenarios. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a lighting device for video shooting, addressing the shortcomings mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a video shooting lighting device, including a support structure and a lighting structure, wherein the support structure includes a fixed box, the top of the fixed box is provided with a damped lifting rod, the top of the lifting rod is provided with a damped bearing seat, and the damped bearing seat is provided with a connecting piece connected to the lighting structure for damped rotation.

[0008] The lighting structure includes a main pole, with multiple hinges around the center of the main pole. A fan-shaped reflector is hinged to each hinge, and a reflective film layer is provided on the inner side of the fan-shaped reflector. An electric push rod is hinged between the rear end of the main pole and the top rear side of the fan-shaped reflector. A lamp structure is provided on one side of the fan-shaped reflector extending from the main pole to the inner side of the fan-shaped reflector.

[0009] Furthermore, the main rod body has a fixing member at its rear end, a damping hinge member at the rear side of the fixing member, and a connecting rod at the end of the connecting member that is damped and hinged to the damping hinge member.

[0010] Furthermore, the lamp structure is a frustum-shaped structure, and multiple lighting lamps are provided on the side of the lamp structure facing the fan-shaped reflector.

[0011] Furthermore, the fixed box is provided with a limiting sliding cavity, the lifting rod extends into the limiting sliding cavity and is provided with a limiting lifting plate, and the bottom of the limiting lifting plate is provided with a damper structure.

[0012] Furthermore, the damping bearing seat is provided with auxiliary plates on both sides, and the bottom of the auxiliary plates is provided with a limiting rod structure extending into the fixed box. The fixed box is provided with a limiting groove that matches the limiting rod structure.

[0013] The advantages of this utility model compared with the prior art are: softer light and improved image quality: by combining the fan-shaped reflector with the high reflective film layer, the direct light of the LED beads is converted into diffused reflected light, avoiding local overexposure and harsh shadows. It is especially suitable for portrait face lighting and product detail shooting, and can restore the true color and texture of the subject.

[0014] Multi-angle adjustment and strong scene adaptability: The damped bearing seat enables 360° horizontal rotation, and the damped hinge enables 0°-90° pitch adjustment. With the electric push rod controlling the opening and closing of the fan-shaped reflector, it can quickly switch between various lighting effects such as "front soft light - side light shaping - backlight contour light", adapting to different shooting scenarios without changing equipment.

[0015] Adjustable range and height, high flexibility: The damping lifting design of the lifting rod adapts to the shooting height, and the opening and closing adjustment of the fan-shaped reflector covers the lighting needs, taking into account both small product shooting and group photo lighting.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Combined with appendix Figure 1-3 A video shooting lighting device includes a support structure 1 and a lighting structure 2. The support structure 1 includes a fixed box 3. The fixed box 3 has a damped lifting rod 4 at its top. The fixed box 3 has a limiting sliding cavity 17. The lifting rod 4 extends into the limiting sliding cavity 17 and has a limiting lifting plate 18. The limiting sliding cavity 17 is used to limit the sliding trajectory of the limiting lifting plate 18 to ensure stable lifting. The bottom of the limiting lifting plate 18 has a damper structure 19. The damper structure 19 can be locked at any height to adapt to different shooting height requirements (such as desktop live streaming and floor portrait shooting).

[0022] The top of the lifting rod 4 is provided with a damping bearing seat 5. The damping bearing seat 5 is provided with a connecting piece 6 connected to the lighting structure 2 for damping rotation. The damping bearing seat 5 is provided with auxiliary plates 20 on both sides. The bottom of the auxiliary plates 20 is provided with a limiting rod structure 21 extending into the fixed box 3. The fixed box 3 is provided with a limiting slide groove 22 that cooperates with the limiting rod structure 21. The damping bearing seat 5 can drive the lighting structure 2360° to rotate horizontally. The limiting rod structure 21 slides along the limiting slide groove 22 to avoid shaking during lifting and rotation and improve stability.

[0023] The lighting structure 2 includes a main pole 10. Multiple hinges 11, numbering 3-6 (preferably 4, evenly distributed around the circumference of the main pole 10), are arranged around the center of the main pole 10. A fan-shaped reflector 12 is hinged to the center of the main pole 10 via the hinges 11, and a reflective film layer 16 (high-reflectivity aluminum film or PET reflective film with a reflectivity ≥90%) is pasted on its inner side. The fan-shaped reflector 12 converts the direct light from the lamp into soft reflected light, avoiding harsh light. An electric push rod 13 is hinged between the rear end of the main pole 10 and the top rear side of the fan-shaped reflector 12. The opening and closing angle of the fan-shaped reflector 12 (opening and closing range 30°-120°) can be controlled by extending and retracting the electric push rod 13, thereby adjusting the lighting. The light range (small angle opening and closing is suitable for close-up lighting, large angle opening and closing is suitable for wide scene lighting), the electric push rod 13 needs to be equipped with a power cord and controller for convenient power supply and control. The fan-shaped reflector 12, the main rod body 10 extends to the inner side of the fan-shaped reflector 12 and is provided with a lamp structure 14, which is a frustum-shaped structure, fixed to the side of the main rod body 10 extending to the inner side of the fan-shaped reflector 12. Multiple lighting lamps 15 are installed on the side facing the fan-shaped reflector 12. The lighting lamps 15 use color temperature adjustable LED beads, with a color temperature adjustment range of 3000K-6500K (3000K warm light is suitable for human skin tone, 6500K cool light is suitable for product color reproduction), and the brightness supports 0-100% stepless adjustment.

[0024] The main rod 10 has a fixing member 8 at its rear end, and a damping hinge member 9 (with a damping plate inside for easy positioning adjustment when adjusting the angle) is provided on the rear side of the fixing member 8. The end of the connecting member 6 has a connecting rod 7 that is damped and hinged to the damping hinge member 9, so as to realize the pitch angle adjustment of the lighting structure (adjustment range 0°-90°).

[0025] Support structure assembly:

[0026] The limiting lifting plate 18 is welded and fixed to the bottom of the lifting rod 4. Then the lifting rod 4 is inserted into the limiting sliding cavity 17 of the fixed box 3 to ensure that the damper structure 19 at the bottom of the limiting lifting plate 18 fits against the inner wall of the bottom of the limiting sliding cavity 17.

[0027] The damping bearing seat 5 is fixed to the top of the lifting rod 4 with bolts. The auxiliary plate 20 is symmetrically welded to both sides of the damping bearing seat 5 so that the limiting rod structure 21 at the bottom of the auxiliary plate 20 is aligned with the limiting slide groove 22 on the inner wall of the fixed box 3 and inserted.

[0028] Connector 6 is connected to damping bearing seat 5 via damping shaft. One end of connecting rod 7 is welded and fixed to connector 6, and the other end is reserved with a hinge hole to cooperate with damping hinge 9.

[0029] Lighting structure assembly:

[0030] A fixing component 8 is welded to the rear end of the main rod 10, and a damping hinge component 9 is installed on the rear side of the fixing component 8 by bolts. The free end of the connecting rod 7 is hinged to the damping hinge component 9 to ensure that the pitch angle can be smoothly adjusted.

[0031] Along the circumferential direction of the middle part of the main pole 10, a hinge 11 is welded every 90°. Each hinge 11 is hinged to one end of the fan-shaped reflector 12. The reflective film layer 16 is pasted on the inside of the fan-shaped reflector 12 with high-temperature resistant adhesive.

[0032] The fixed end of the electric push rod 13 is hinged to the bracket at the rear end of the main rod 10, and the telescopic end is hinged to the ear plate at the top rear side of the fan-shaped reflector 12 to ensure that the electric push rod can drive the fan-shaped reflector to open and close when it extends or retracts.

[0033] A frustum-shaped lamp structure 14 is welded to one side of the main pole 10 extending to the inside of the fan-shaped reflector 12, and 12-16 LED beads are evenly installed on the inclined surface of the lamp structure 14. The power supply lines connecting the LED beads can be threaded through the inside of the main pole to ensure aesthetics.

[0034] II. Actual Use

[0035] Height Adjustment: Depending on the shooting scene, manually pull the lifting rod 4 up or down. The limiting lifting plate 18 slides along the limiting sliding cavity 17. The damping force generated by the damper structure 19 can lock the lifting rod at any height, preventing slippage. The limiting rod structure 21 slides synchronously along the limiting slide groove 22, ensuring smooth lifting.

[0036] Angle adjustment:

[0037] Horizontal angle adjustment: Rotate the damping bearing seat 5 to drive the lighting structure 2 to rotate around the central axis of the lifting rod 4. After adjusting to the target direction, the damping force of the damping bearing seat can lock the angle.

[0038] Pitch angle adjustment: Manually push the lighting structure 2 to rotate around the damping hinge 9 to adjust the pitch angle of the lamp structure 14. The damping force can lock the current angle.

[0039] Light range and softness adjustment:

[0040] The opening and closing of the fan-shaped reflector 12 is controlled by the extension and retraction of the electric push rod 13: when a narrow range of strong light is needed, the electric push rod is controlled to retract, reducing the opening and closing angle of the reflector by 30°, and the light is concentrated and reflected by the reflective film; when a wide range of soft light is needed, the electric push rod is controlled to extend, increasing the opening and closing angle of the reflector, and the light is diffused and reflected.

[0041] Adjust the color temperature and brightness of the lighting fixture 15 according to the scene requirements: set it to 3000K color temperature and 70% brightness when shooting warm-toned portraits; set it to 6500K color temperature and 100% brightness when shooting cool-toned products.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
