Description

Technical Field

[0001] This utility model belongs to the field of film and television equipment technology, and in particular relates to a softbox. Background Technology

[0002] A softbox consists of four parts: a reflective cloth, a diffuser cloth, a support rod, and a mount. The softbox connects to the studio light via the mount. It cannot be used alone and is an accessory for the studio light. When mounted on a studio light, a softbox produces even, soft light with good color saturation. Softboxes typically use reflective materials and diffuser cloth to create a larger, more uniform light source, resulting in softer, more vibrant light and sharper colors. This also helps eliminate glare and shadows in videos and photos.

[0003] Existing softboxes, for ease of carrying, have buckles, support rods, and reflective fabric structures similar to umbrellas that can be folded and unfolded. After unfolding, the softbox fabric is then fitted onto the front port of the softbox for easy carrying and use. For example, in an insert-type LED film and television light softbox disclosed in publication number CN109001954A, the inner side of the mounting rod (support rod) is connected to the reflective fabric via a first Velcro fastener; the edge of the softbox fabric is provided with a first elastic ring, which is fitted onto one end of the protective cover. The technical solution involves attaching the softbox to several support rods by setting a first elastic ring at the edge of the softbox. However, in practice, it has been found that softboxes come in various sizes to meet the needs of different films and television programs, ranging from as small as 40 centimeters to as large as over 2 meters. This results in the softbox having a larger weight, making the connection between the softbox and the support rods using the first elastic ring method unstable. This can easily lead to a decrease in the flatness of the softbox and the appearance of wrinkles. Furthermore, sometimes the softbox needs to be tilted downwards at a certain angle, which further reduces the flatness of the softbox and is not conducive to softening the studio lighting.

[0004] To address the shortcomings of existing technologies, this utility model discloses a softbox. By setting reinforcement members at each support rod position along the edge of the softbox fabric and connecting the reinforcement members to the internal threaded holes at the ends of the support rods via fastening bolts, the connection stability between the softbox fabric and the support rods is improved, ensuring the flatness of the softbox fabric. This design is well-suited for use in larger softboxes and when the softbox needs to be tilted downwards at a certain angle. Utility Model Content
