Through the atomizing piece of different thickness or material, can realize different degree of atomizing effect, thereby creating multi-level light effect from soft to heavy on the same stage. Atomizing piece can help to soften direct light, reduce hard edge shadow, makes stage lighting more natural and harmonious, improves overall visual experience. Proper atomizing effect can create dream, romantic or mysterious stage atmosphere, has important auxiliary role to drama, concert, dance performance and other various performance forms.
