Abstract
A photographic apparatus having ring light module includes a camera, a support base and a plurality of light units. The camera has a lens having an optical axis. The support base is connected to the camera and surrounds the lens. The support base includes an outer peripheral wall, an inner peripheral wall, and a bottom wall connected the outer peripheral wall and the inner peripheral wall. The bottom wall and the outer peripheral wall and the inner peripheral wall cooperatively define an accommodating groove. The angle between the bottom wall and the inner peripheral wall is an acute angle. The light units are arranged in the accommodating groove and fixed on the bottom wall and emit light beams in an oblique direction with respect to the optical axis.
