Title:
LIGHT BEAM CUTTING DEVICE CAPABLE OF PRECISELY PERFORMING POSITIONING AND STAGE LAMP COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/021825
Kind Code:
A1
Abstract:
A light beam cutting device capable of precisely performing positioning. The light beam cutting device capable of precisely performing positioning comprises a base plate (100), a plurality of cutting blades (200) mounted on the base plate (100), and a driving mechanism driving the cutting blades (200) to move. A first light through hole (110) for a light beam to pass through is provided in the base plate (100), the plurality of cutting blades (200) are arranged around the first light through hole (110), the driving mechanism drives the cutting blades (200) to reciprocate between shielding and opening the first light through hole (110), each of the cutting blades (200) is provided with at least two driving mechanisms, each driving mechanism comprises a driving gear (320) and a driving plate (330), the driving plate (330) is hinged to the cutting blade (200), and the driving plate (330) is provided with a rack (331) meshing with the driving gear (320). According to the light beam cutting device, the driving mechanism with the driving gear (320) and the rack (331) in transmission is used to drive the cutting blades (200), the position of the cutting blade (200) in a cutting process can be precisely controlled, the cutting precision of the cutting blade (200) in the cutting process is effectively improved, and the consistency and accuracy of cutting patterns are ensured. Further disclosed is a stage lamp.
