Abstract
A ceiling lamp may include: a base plate and a light emitting component arranged on the base plate. The ceiling lamp further includes a diffusing structural member, arranged outside the light emitting component and configured to evenly diffuse light emitted by the light emitting component; and a light transmitting structural member, arranged outside the diffusing structural member. The light transmitting structural member is provided with a microprism structure, and is configured to allow the light evenly diffused by diffusing structural member to form into a pattern corresponding to the microprism structure on the light transmitting structural member.
