An optical system for stage lamp comprises a light source (10), a light condensing device (20), an effect component (30), a lens (40) and a multi-reflection mirror surface optical component (50) fixed on the upper part of the lens (40). Light emitted by the light source (10) is reflected by the light condensing device (20) and converged to become a main light beam (11) along the transmission direction of the light. The main light beam (11) sequentially passes through the effect component (30) and the lens (40) and is reflected by the multi-reflection mirror surface optical component (50). The multi-reflection mirror surface optical component (50), at least comprising three reflection mirror surfaces, is connected with at least three stage of linkage mechanisms which can drive the multi-reflection mirror surface optical component (50) to move to achieve a three-dimensional dynamic light spot effect. When the optical system is applied to the stage lamp, a lighting effect that multiple dynamic light spots are simultaneously shown by a single lamp is achieved. |
