Technical Field

[0001] The utility model relates to the technical field of underwater photography, in particular to an underwater camera with an angle-adjustable lighting function. Background Art

[0002] As a device specially designed for underwater photography, underwater cameras are widely used in many fields, including oil, deep-water exploration, underwater operations, marine fisheries and other underwater fields. Since part of the sunlight will be reflected back above the water surface after entering the water, less light actually enters the water body, and the deeper the depth, the less light enters the water body. Therefore, underwater photography is usually equipped with additional lighting for light compensation to improve the clarity of the photography.

[0003] However, current underwater cameras usually fix the lighting lamp on the outside of the body, and the light direction of the camera lens and the lighting lamp is consistent. This design cannot adjust the illumination angle of the lighting lamp, and the actual lighting range of the lighting lamp is limited. When the photographic object is large, the lighting lamp can only illuminate the central area of ​​the photographic object, and cannot provide good lighting for the edge of the photographic object, resulting in unsatisfactory photographic effect. In addition, due to the complex underwater light conditions, fixed lighting lamps may cause insufficient light or excessive light during underwater photography, which may cause color distortion of the photographic object, and the efficiency and quality of underwater photography are low.

Four groups of lighting lamps 6 are respectively arranged on the outer side of the support seat 2 at intervals of 90 degrees, that is, the four lighting lamps 6 are circumferentially arranged on the outer side of the photographic lens 3, providing good lighting conditions for the photographic lens 3. By controlling the driving component, the driving component drives the rotating rod 5 and the lighting lamp 6 fixed on the rotating rod 5 to rotate together with the center of the first connecting seat 4 as the axis, adjusts the illumination angle of the lighting lamp 6, and expands the illumination range of the lighting lamp 6.
