Title:
DEVICE FOR CONVERTING LASER BEAM INTO BEAMS DIFFUSED IN CURVED PATTERN
Document Type and Number:
WIPO Patent Application WO/2020/009298
Kind Code:
A1
Abstract:
Disclosed is a device for converting a straightly incident laser beam into beams diffusively emitted in a curved pattern on a predetermined plane. The device for converting a laser beam into beams diffused in a curved pattern may comprise a housing and a lens part, wherein the lens part may be coupled to the housing between the inner side walls of the housing while forming a predetermined angle between the center axis of the lens part and the center axis of the housing, so as to allow a laser beam, reflected from or passing through the lens part, to be diffusively emitted in a circular or curved pattern. The housing has a reflection surface formed in an inner side wall portion of the housing, onto which a laser beam reflected from or passing through the lens part is emitted, so as to reflect the laser beam, whereby a laser beam reflected by the reflection surface may overlap, on the predetermined plane, a laser beam emitted without being reflected by the reflection surface.
