| 摘要 |
The present invention relates to a stage lighting optical system including spot and beam effects simultaneously, comprising a light source assembly from which condensed light can be emitted (1), an object assembly, and a zoom lens assembly, which are located in a same primary optical axis direction. The light from said light source assembly (1) is cast by the object assembly and the zoom lens assembly. Wherein, said object assembly include an object for beam mode assembly (21) and an object for gobo mode assembly (22) that can be switched with each other and enter to the primary optical axis. Said light source assembly (1) can move forward or backward along the primary optical axis with respect to the object assembly. When the light source assembly moves forward to a first position with respect to the object assembly, the beam design assembly (21) is switched to the primary optical axis. When the object for beam mode assembly (1) moves backward to a second position with respect to the design assembly, the object for gobo mode assembly (22) is switched into the primary optical axis. The present invention possesses advantages such as low light loss and high utilization efficiency. |
