Abstract
This application provides a lighting accessory and a photographic lamp. The lighting accessory includes a light-transmission member, a light-shielding member and a connection assembly. The light-transmission member and the light-shielding member are both in a shape of a hollow cylinder. The light-transmission member includes a cylindrical first light-transmission surface and a flat second light-transmission surface blocked at one end of the first light-transmission surface. An inner cavity of the hollow cylinder of the light-transmission member is configured to accommodate a lamp body. The light-shielding member is arranged round an outer side of the first light-transmission surface and is spaced from the first light-transmission surface in a radial direction. The light-transmission member, the light-shielding member and the lamp body are connected through the connection assembly. The connection assembly also enables the light-emitting surface of the lamp body to be opposite to the first light-transmission surface.
