Abstract

The present disclosure discloses a projection lamp. The projection lamp includes a light-emitting assembly including at least one first non-coherent light source, a light-reflection medium, a first condensing lens, a driving device, a driving gear, and a driven gear. An inner wall surface of the light-reflection medium is formed by mutually connecting a plurality of irregular light reflection surfaces; the first non-coherent light source is arranged in the light-reflection medium; the first condensing lens is arranged above the light-reflection medium; the driving gear is connected to the driving device; and the driven gear is arranged on the light-reflection medium and is engaged with the driving gear to drive the light-reflection medium to rotate. The technical solution of the present disclosure effectively improves the diversity of the light effect of the projection lamp.
