Abstract:
The present utility model discloses a composite effect disc device and a stage lamp having same. The composite effect disc device comprises an effect disc, a first driving unit for driving the effect disc to rotate, and a second driving unit for driving the effect disc to shift, the effect disc comprises a plurality of circles of light-transmitting rings surrounding the center of a disc body of the effect disc, each of the light-transmitting rings has an effect band for generating a light effect, and at least two of the light-transmitting rings are provided with light through holes allowing light beams to pass through freely. The at least two of the light-transmitting rings are provided with the light through holes; when an intersection part of the effect disc and an optical path needs to be switched from the effect band to the light through holes, under driving of the first driving unit and the second driving unit, the effect disc can select to switch, to the optical path, the light through hole closest to the optical path, so that the switching time is greatly reduced, enabling the light beam effect of the stage lamp to be smoothly switched.
