Technical Field

[0001] The utility model relates to the technical field of photographic equipment, in particular to a fabric background component with built-in lighting. Background Art

[0002] A photo backdrop is a material placed behind the subject during photography. As a crucial component of the image, it serves to highlight the subject, create atmosphere, and enhance the visual impact. There are many different types of backdrops, with varying materials, colors, sizes, and patterns to suit different themes and styles.

[0003] Common photography background cloths are mostly simple fabric structures. Some background cloths for outdoor use can be folded, while some background cloths for indoor use require a supporting structure such as a bracket to be hung when laid out. However, such brackets can only play a supporting role when installing the background cloth. When not in use, staff need to manually remove the background cloth to prevent dust from falling, which is very inconvenient. In view of this, we propose a fabric background component with built-in lighting. Utility Model Content

The design of the pull plate 19 allows the user to conveniently operate the slide 17 and insert 18 by pulling on the pull plate 19, making operation more convenient. The pull hole 191 provides a better grip for the user, enhancing comfort and accuracy.

[0037] It should be added that the reinforcing layer 231 in this embodiment is made of non-woven fabric material, which has the advantages of light weight, easy cleaning and high structural strength. The base fabric layer 232 in this embodiment is made of polyester fabric material, which has the characteristics of wrinkle resistance, non-fading resistance, and long service life. The material has strong light transmittance and is conducive to reflection; the light-transmitting layer 233 in this embodiment is made of gauze material, which has the advantages of fine yarn, soft texture and good light transmittance, which is conducive to light transmission to provide background light effect for taking pictures.

[0038] During specific use, the user first pulls the limit bar 24 to the front side, and the limit bar 24 drives the background cloth 23 to move to the front side. The background cloth 23 drives the rotating shaft 21 to rotate, and the spiral spring 22 is compressed. Then the user passes the connecting block 25 through the vertical plate 11 on the front side, and at the same time the user pulls the pull plate 19, and the pull plate 19 drives the slide plate 17 to slide along the two connecting rods 15. The spring 16 is compressed by the slide plate 17, and the insert block 18 is retracted into the shell 14 at the same time. When the slot moves to one side of the insert block 18, the user releases the pull plate 19, and under the elastic action of the spring 16, the insert block 18 is inserted into the slot, the limit bar 24 is fixed, and the background cloth 23 is unfolded. Finally, the user turns on the power of the LED light bar 26, and the LED light bar 26 starts to work and emits light.
