Abstract
A ring-shaped light-distribution component includes a light-distribution component body that has a ring-shaped accommodation space and a light incident surface and a light emergent surface respectively located on two sides of the light-distribution component body. The ring-shaped accommodation space accommodates at least two light-emitting units distributed along its circumference. An inner wall of the ring-shaped accommodation space is the light incident surface, the light incident surface including an inner light incident surface near the center of the ring light-distribution component and an outer light incident surface away from the center. A deflection angle of light projected by the light-emitting unit and deflected by a portion of the light-distribution component body corresponding to the inner light incident surface is a first deflection angle, and a deflection angle of light deflected by a portion of the light-distribution component body corresponding to the outer light incident surface is a second deflection angle.
