Description

Technical Field

[0001] This application belongs to the field of green screen lighting technology, specifically relating to a lighting structure that assists in replacing green screen backgrounds. Background Technology

[0002] A green screen is essentially a backdrop using green as its background color, typically made of a special non-reflective, uniformly light-absorbing material. It primarily achieves background replacement based on optical principles: because the colors of common objects like human skin and clothing differ significantly from green, during filming, the camera captures the image of a person or object in front of the green screen. Later, video editing software uses color keying technology to identify and remove the specific green background color from the image, creating a transparent channel. Other pre-prepared background materials are then filled in, achieving the background replacement effect. This technology is widely used in film and television special effects production, allowing actors to "immerse" themselves in virtual fantasy worlds and vast universes; in television program production, it can create diverse virtual studio scenes; and in the field of online live streaming, anchors can use green screens to switch between different styles of live streaming backgrounds at any time. Using green screen backdrops not only reduces the cost and difficulty of building physical sets but also greatly expands creative space, allowing creators to easily realize their wildest imaginations.

[0003] Currently, it has been found that lighting effects play a crucial role in the quality of green screen chroma keying when using green screen backgrounds. Traditional lighting structures used to replace green screen backgrounds typically employ fixed installations or simple manual adjustments. Fixed installations cannot be flexibly adjusted according to changes in the shooting scene, actor positioning, and shooting angle, easily leading to uneven lighting on the green screen, resulting in shadows or reflections, which seriously affect the chroma keying effect and post-production quality. Simple manual adjustments are not only cumbersome and time-consuming, requiring repeated manual adjustments, but also difficult to achieve precise angle and height control, failing to meet the needs of precise lighting positioning in complex shooting scenes.

[0024] Example 1:

[0025] Please see Figure 1 As shown, a lighting structure for assisting in green screen background replacement includes:

[0026] The housing 1 has reflectors 2 rotatably connected to all four sides of its bottom. A supplementary light 3 is installed inside the bottom side of the housing 1. An adjustment component 4 is provided on the top of the housing 1.

[0027] As can be seen from the above, after the green screen background is replaced, the position of the fill light 3 inside the housing 1 is adjusted by adjusting component 4 so that the fill light 3 can illuminate the replaced green screen background. When the fill light 3 is illuminating, the light illuminating the fill light 3 is focused by the reflectors 2 around the perimeter.

[0028] Specifically, regarding the aforementioned adjustment component 4, please refer to... Figure 2 and Figure 3 As shown, the adjustment component 4 includes an electric telescopic rod 41, a base 42 is fixedly connected to the end of the electric telescopic rod 41, a plurality of through holes 43 are provided on the base 42, a mounting bracket 44 is fixedly connected to the telescopic end of the electric telescopic rod 41, a servo motor 45 is installed inside the mounting bracket 44, and a suspension bracket 46 is provided on the housing 1.

[0029] As can be seen from the above, before use, the device is installed in the corresponding position through the multiple through holes 43 on the base 42; during subsequent adjustment, the suspension frame 46 and the housing 1 are moved up and down by the extension and retraction of the electric telescopic rod 41. After the suspension frame 46 and the housing 1 are moved to the appropriate area, the suspension frame 46 and the housing 1 are rotated by the servo motor 45 to adjust the position of the supplementary light 3 at the bottom of the housing 1.

[0030] Preferably, the electric telescopic rod 41 is vertically mounted on the top of the suspension frame 46, and the suspension frame 46 is drivenly connected to the output end of the servo motor 45;

[0031] As can be seen from the above, the suspension frame 46 moves up and down following the electric telescopic rod 41 as it extends and retracts. After moving to the corresponding position, the suspension frame 46 is driven to rotate by the servo motor 45.

[0032] Example 2:

[0033] refer to Figure 3 and Figure 4 As shown, a rotating shaft 47 is fixedly connected to the inner side of the housing 1, and a gear 48 is fixedly connected to the rotating shaft 47. A self-locking motor 49 is provided inside the housing 1, and a gear 410 is fixedly connected to the output end of the self-locking motor 49.

[0034] As can be seen from the above, during adjustment, the self-locking motor 49 drives the gear 2 410 to rotate, and the rotation of the gear 2 410 will drive the gear 1 48 to rotate, which in turn drives the rotating shaft 47 to rotate. At this time, the rotating shaft 47 drives the housing 1 to deflect and adjust inside the suspension frame 46.

[0035] Preferably, the rotating shaft 47 is rotatably connected to the suspension bracket 46, and the rotating shaft 47 is arranged laterally inside the housing 1;

[0036] As can be seen from the above, the rotating shaft 47 is horizontally arranged inside the housing 1, and the rotating shaft 47 is rotatably connected to the suspension frame 46, so that the rotating shaft 47 can rotate on the suspension frame 46, and the rotating shaft 47 will drive the housing 1 to rotate when it rotates.

[0037] Preferably, gear 48 is disposed on one side of gear 410, and gear 48 meshes with gear 410;

[0038] As can be seen from the above, by meshing gear 48 and gear 410, gear 410 will transmit power to gear 48 when it rotates.

[0039] Preferably, the self-locking motor 49 is disposed on one side of the rotating shaft 47, and the self-locking motor 49 is fixed inside the housing 1 by the fixing bracket 411;

[0040] As can be seen from the above, the self-locking motor 49 is installed inside the housing 1 by the fixing bracket 411, and the self-locking motor 49 is set on one side of the rotating shaft 47 to facilitate the subsequent driving of the rotating shaft 47 to rotate.

[0041] Working principle: Before use, the device is installed in the corresponding position through the multiple through holes 43 on the base 42. During subsequent adjustment, the electric telescopic rod 41 is used to extend and retract, which drives the suspension frame 46 and the housing 1 to move up and down. After the suspension frame 46 and the housing 1 are moved to the appropriate area, the servo motor 45 drives the suspension frame 46 and the housing 1 to rotate. Then, the self-locking motor 49 drives the gear 2 410 to rotate. When the gear 2 410 rotates, it will drive the gear 1 48 to rotate, which will drive the rotating shaft 47 to rotate. At this time, the rotating shaft 47 drives the housing 1 to deflect and adjust inside the suspension frame 46, thereby adjusting the height, horizontal angle and deflection angle of the supplementary light 3.

[0042] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
