Abstract
A jewelry lighting lamp has a lighting part, a rotating part and a mounting part, the mounting part has a lamp barrel which accommodates the lighting part and rotating part. The rotating part has a driving motor, which drives the lighting part to rotate along the central axis of the lamp barrel; the lighting part has a main light source arranged on the central axis and one or more secondary light sources arranged around the main light source, the main light source and the secondary light source are driven by the rotating part to rotate along the central axis circumferentially. A jewelry lighting method using the jewelry lighting lamp is also provided. By varying luminance, the lamp solves the problem of visible light and shadows at the edge of the aperture when there are main and auxiliary light sources with different luminance.
