Description

Technical Field

[0001] The present invention relates to the technical field of electronic products, and specifically to an adjustable fill light device for short video live broadcast and a method of using the same. Background Art

[0002] Fill lighting for short video live streaming is a key auxiliary device for improving image quality during live streaming. It can compensate for insufficient ambient light, especially in dim or backlit scenes. By providing even, soft light, it eliminates facial shadows, making the host's image clearer and more three-dimensional, avoiding dim and blurry images and improving the overall visual experience. Proper use of fill lighting can adjust the brightness and brightness, and the warm and cool tones, to create different atmospheres. For example, warm light creates a warm and friendly feeling, while cool light brings a professional and calm feeling. Suitable for live streaming scenarios such as food, beauty, and knowledge sharing, it makes the images more attractive and appealing.

[0003] A fill light device usually consists of a bracket and a light ring. However, the height, pitch angle, and horizontal angle of some current fill light devices cannot be adjusted, which will cause the following problems. For example, the height and body shape of anchors vary greatly. For tall anchors, a fill light ring with a fixed height may only illuminate the forehead or chin, resulting in uneven lighting on the face and a "yin-yang face"; for short anchors, the light may be too strong and glaring, or it may not fully illuminate the face, affecting the anchor's image. Live broadcasts are diverse, including sitting broadcasts, standing broadcasts, close-ups, and panoramic views. When broadcasting while sitting, a fill light with a fixed height may not be able to take into account the anchor's face. Compared with the fill light of desktop products; when broadcasting standing up, the light circle is too low, the light is only concentrated on the legs, and the face and upper body are underexposed. When there is a strong light source such as a window behind the anchor, the fixed-angle fill light cannot adjust the pitch angle to offset the backlight, resulting in the anchor's face being too dark, the background being too bright, the main body of the picture not being prominent, and the audience having difficulty seeing the anchor's expression and movements. Different live broadcast themes require different lighting atmospheres. For example, beauty live broadcasts require warm light to highlight the makeup texture, and knowledge sharing live broadcasts require cold light to create a sense of professionalism. The fill light with non-adjustable angle cannot switch the atmosphere through changes in light angle and brightness, and the live broadcast effect is single and lacks appeal.

During the up and down movement of the movable column 3, the slide blocks 23 can drive the slide blocks 23 to slide along the inner wall of the vertical groove 24, so that the movable column 3 can only move up and down, and limit the up and down movement range of the movable column 3. A partition 5 is bolted to the inner wall of the shell 1, and a first motor 6 is bolted to the surface of the partition 5. A screw 7 is also rotatably connected to the surface of the partition 5. The output shaft of the first motor 6 is connected to the screw 7 through a gear transmission. A threaded groove 4 is provided inside the movable column 3 , and the screw 7 is threadedly connected to the inner wall of the thread groove 4, the top of the movable column 3 is bolted to the box body 8, and the surface of the box body 8 is rotatably connected to the rotating column 9. The inside of the box body 8 is also bolted to a second motor 10, and the output shaft of the second motor 10 is connected to the rotating column 9 through a gear transmission. Both ends of the rotating column 9 extend to the outside of the box body 8 and are bolted to a connecting plate 12. A locking assembly 22 is also provided inside the box body 8, and the other side of the connecting plate 12 is bolted to a box body 13. The inner wall of the box body 13 is rotatably connected to a rotating rod 14, and the inside of the box body 13 is also bolted to a third motor 15. The output shaft of the third motor 15 is connected to the rotating rod 14 through a gear transmission. The top of the rotating rod 14 extends to the top of the box body 8 and is bolted to the bottom of the lamp ring body 16. A horizontal cylinder 17 is provided on all three sides of the shell 1. The inner wall of the horizontal cylinder 17 is slidably connected to a horizontal plate 18. The bottom of the horizontal plate 18 is bolted to a roller 19.

[0031] The transmission assembly 27 includes a vertical rod 271, a connecting plate 272 and a transmission rod 273. The vertical rod 271 and the bottom end of the screw 7 are welded to each other, the connecting plate 272 is bolted to the inside of the horizontal cylinder 17, and the transmission rod 273 is rotatably connected to the surface of the connecting plate 272.

A button is set on the surface of the device, and control can be implemented through the button.

[0034] A method for using an adjustable fill light device for short video live broadcasting, the method comprising the following steps:

[0035] Step a: First, turn on the first motor 6. Its output shaft drives the screw 7 to rotate through the gear. The movable column 3 drives the box body 8, the box body 13 and the upper lamp ring body 16 to rise synchronously under the action of the thread, thereby adjusting the height of the lamp ring body 16.

[0036] Step b: The screw 7 drives the vertical rod 271 to rotate, and drives the transmission gear 276 to rotate through the transmission rod 273 and the transmission column 275, so that the horizontal plate 18 moves toward the outside of the horizontal tube 17, increasing the extension length of the horizontal plate 18. The horizontal plate 18 drives the roller 19 to move synchronously, so that the support point of the roller 19 is moved away from the center of the housing 1. While raising the height of the lamp ring body 16, the support point can be moved away from the center of the device, thereby increasing the stability of the device.

[0037] Step c: Turn on the second motor 10 to drive the rotating column 9 to rotate. The rotating column 9 drives the connecting plate 12 and the box 13 to make a circular motion, thereby driving the upper light ring body 16 to change the pitch angle;

[0038] Step d: Turn on the electric push rod 221 to extend its output shaft, thereby driving the clamping plate 222 to press against the surface of the rubber ring 223, thereby locking the rotating column 9 through friction to prevent the rotating column 9 from rotating freely;

[0039] Step e: Turn on the third motor 15 , and its output shaft drives the rotating rod 14 to rotate through the gears. Then the rotating rod 14 drives the upper light ring body 16 to rotate synchronously, so as to adjust the horizontal angle of the light ring body 16 .

[0040] Through 360° horizontal rotation and ±90° pitch angle adjustment, the direction of light projection can be precisely controlled to solve the problems of uneven facial shadows or dark backgrounds caused by the fixed angles of traditional fill lights. It should be used in scenes such as standing / sitting switching and multiple people in the same frame to avoid chin shadows caused by low-position fill light or the "top-light ghost face" effect caused by high-position fill light. When multiple lights are linked, three-point lighting (main light + auxiliary light + contour light) can be achieved by adjusting the height and pitch angle of each light, which improves the picture texture. Moreover, when the height of the light ring is increased, the corresponding support points expand outward to increase stability.

[0041] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.
