STAGE LIGHTING OPTICAL SYSTEM HAVING PATTERNING AND LIGHT BEAM EFFECTS

Title:

STAGE LIGHTING OPTICAL SYSTEM HAVING PATTERNING AND LIGHT BEAM EFFECTS

Document Type and Number:

WIPO Patent Application WO/2015/135256

Kind Code:

A1

Abstract:

A stage lighting optical system having at the same time patterning and light beam effects, and comprising, arranged on a same principal light axis, a light source component (1) capable of emitting focused light, a patterning component, and a focusing lens component, the light rays of said light source component (1) being projected through the patterning component and the focusing lens component. The patterning component comprises a light-beam patterning component (21) and a graphics patterning component (22) able interchangeably to be switched into the principal light axis; the light source component (1) is movable back and forth along the principal light axis relative to the patterning component; when the light source component moves forward relative to the patterning component to a first position, the light-beam patterning component (21) is switched into the principal light axis; when the light source component (1) moves rearward relative to the patterning component to a second position, the graphics patterning component (22) is switched into the principal light axis. The present stage lighting optical system features low light consumption and a high light utilization rate.
