Description

Technical Field

[0001] The utility model relates to the technical field of backlight source equipment, in particular to a multi-angle adjustable backlight source structure. Background Art

[0002] Fill lights and backlights are widely used in photography. Backlight, also known as rim light, projects light onto the subject's head and shoulders, making them stand out against the background. It's often used in darker scenes to prevent the subject from blending into the background. The height and distance of the backlight can be adjusted to ensure a clear outline of the subject.

[0003] However, most of the existing backlights on the market are only composed of a backlight panel and a bracket. By adjusting the bracket, the height and distance of the backlight panel can be changed, and the contour light can be projected onto the subject. However, this method has insufficient adjustment ability and cannot make the backlight panel illuminate the subject from all angles. The adjustment needs to be done manually, which is very troublesome and inconvenient. It is also impossible to move and adjust the position and angle of the backlight panel during the shooting process, which has limitations. Utility Model Content
