Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of International Application No. PCT/CN2023/128374, filed on Oct. 31, 2023, and claims priority to Chinese Patent Application No. 202222950143.1, filed on Nov. 4, 2022, the entire disclosures of which are hereby incorporated herein by reference. TECHNICAL FIELD The present application relates to the technical field of a photographic equipment, and particularly to an air bag and an air bag lamp. BACKGROUND With the development of the information age, people's requirement for photography and videography is increasing. During the existing photography and videography processes, various soft light devices are often required. As a new type of soft light device, the air bag lamp is equipped with a airbag, such that the light emitted by the LED light source can to be scattered through the air in the airbag and the soft light cloth on the outer side of the airbag, with a better soft light effect, and it only needs to be inflated before use, and the operation is relatively convenient. Therefore, due to its good soft light performance, portability, simple operation and other characteristics, the air bag lamp in the market become more and more popular. The light source of the existing air bag lamp is usually installed on portion of the side surface of the airbag. The light emitted by the light source is directed into the airbag, and then passes through the air in the airbag and is emitted from the side surface of the other portion of the airbag. As a result, the light cannot be emitted outward from the side surface of the air bag where the light source is installed, resulting in a smaller illuminated surface of the air bag lamp, which makes the air bag lamp impossible to emit light comprehensively, leading to a poor lighting effect and affecting the user experience. SUMMARY There are provided an air bag and an air bag lamp according to embodiments of the present application. The technical solution is as below: According to a first aspect of embodiments of the present application, there is provided an air bag, which includes: an outer cylinder and an inner cylinder provided inside the outer cylinder; where the inner cylinder is transparent, a cavity is provided inside the inner cylinder, and a side surface of the outer cylinder is a soft light surface;an annular and enclosed inflation cavity is formed between the outer cylinder and the inner cylinder;where the air bag is provided with an inflation opening in communication with the inflation cavity for inflating the air into the inflation cavity, to make the air bag expand;an installation opening is opened at an end of the air bag and corresponds to an end of the inner cylinder; andthe installation opening is in communication with the cavity inside the inner cylinder for installment of the light source, and the light emitted by the light source is capable of passing through the inflation cavity and the soft light surface in sequence and then emitted out of the air bag. According to a second aspect of embodiments of the present application, there is provided an air bag lamp, including a light source and the air bag as mentioned above, where the light source is provided at the installation opening of the air bag.
