Title:
STAGE LAMP OPTICAL SYSTEM WITH LIGHT BEAM AND PATTERN EFFECTS, AND LIGHT PROJECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/223959
Kind Code:
A1
Abstract:
The present invention relates to a stage lamp optical system with light beam and pattern effects, and a light projecting device. The optical system comprises a laser light source, a first light guide assembly, an LED light source, a second light guide assembly, and a plurality of optical lens assemblies which are sequentially arranged along a principal optical axis. Openings are formed on the LED light source and the second light guide assembly at positions directly facing the first light guide assembly; after light of the laser light source penetrates through the first light guide assembly or light of the LED light source penetrates through the second light guide assembly, the light sequentially passes through the plurality of optical lens assemblies, thus forming a light beam outlet mode or a pattern light outlet mode. According to the stage lamp optical system in the present invention, lasers transmitted from the first light guide assembly and LED light transmitted from the second light guide assembly sequentially pass through the plurality of optical lens assemblies and then can form the light beam outlet mode or the pattern light outlet mode, and switching between the light beam effect and the pattern effect can be implemented by switching work of the laser light source and work of the LED light source; the structure is simple, manufacturing costs are reduced, and operations are quite convenient during switching between the light beam effect and the pattern effect.
