Description

Foldable Shooting Lights}

The present invention relates to lighting for product photography, and more particularly, a bar-shaped first bar in which one or more lighting units are formed, and a second bar-shaped coupling part connected to both ends of the first bar, respectively, to be rotatably connected by a joint and rotating flanges are connected to both ends of each lighting unit so that the lighting unit is rotatable within a certain angular range with the longitudinal direction of the first bar and the second bar as an axis. To secure a light source in at least three directions by adjusting individually, and to a folding photography lighting that can be stored by folding the first bar and the second bar through a joint when the photographing lighting is not in use.

The annual transaction amount through online shopping exceeded KRW 111 trillion in 2018 and is expected to exceed KRW 189 trillion in 2022. With the development of logistics services such as , courier and delivery, the transaction of goods through online shopping is gradually increasing.

In particular, since online shopping malls can be established and operated without a separate store, it is possible to save various expenses such as store rental costs, interior costs, or franchise agreement costs, and consumer access is not restricted depending on the location of the store. As a result, the barrier to entry is significantly lower than that of the existing method of opening a store, and the number of small business owners challenging online startups is gradually increasing.

When a consumer purchases a product from an online shopping mall, he or she decides whether to purchase the product by looking at a photograph or video of the product. It will also require a fitting model or product shooting and editing skills.

However, in the case of a small personal online shopping mall like the one above, the cost of renting a studio or professional shooting equipment such as a camera and lighting, or the labor cost of putting in a professional manpower for shooting or editing, is greatly burdened. The proportion of producing content for sale is gradually increasing.

In addition, as the photo or video service market through SNS or online streaming is recently activated, the number of creators is gradually increasing. In the case of a single creator, the simplification of shooting and lighting equipment is difficult because they have to take charge of video shooting, sound recording, and lighting work by themselves. It is essential.

Therefore, the demand for filming equipment that allows online small business owners or single creators to easily shoot is increasing, and Korean Patent Registration No. 10-2111721 (registered on May 11, 2020) simplifies the connection between LED lights and emits light. We propose an LED lighting device that improves the convenience of fastening for flexible LED lights that can secure the surface.

However, the above LED lighting device is difficult to move and store after use due to the size of the LED light, and the weight is greatly increased because the LED light is combined in a separate stand, and it takes time to install the LED light.

In particular, in the case of lighting, if the light source is placed on one side, a shadow may be formed behind the subject in the opposite direction to the light source. , it can be a huge burden for online small business owners who are not familiar with shooting products for sale, and it was difficult for a single creator to use this to create content without a shooting staff to help with the use of additional lighting or reflectors.
