Stage lamp optical system having beam and pattern effects and light projecting device

摘要

The present invention discloses a stage lamp optical system having beam and pattern effects comprising a laser light source, a first light guide component, an LED light source, a second light guide component and a plurality of optical lens components, which are sequentially arranged along a main optical axis, wherein both the LED light source and the second light guide component are provided with an opening at a position directly facing the first light guide component; and after the light from the laser light source passes through the first light guide component or after the light from the LED light source passes through the second light guide component, the light sequentially passes through the plurality of optical lens components to form a light output in a beam mode or in a pattern mode.
