Title:
TILED LIGHT SOURCE FOR MULTI-SIZED PHOTOCURING 3D PRINTER
Document Type and Number:
WIPO Patent Application WO/2021/258524
Kind Code:
A1
Abstract:
A tiled light source for a multi-sized photocuring 3D printer, comprising an optical lens assembly (12) and lamp panel assemblies (31, 32, 33); the lamp panel assemblies (31, 32, 33) are located below the optical lens assembly (12), the lamp panel assemblies (31, 32, 33) comprise several independent lamp panels, and the independent lamp panels are arranged side by side. Multiple small-sized light sources are used to be tiled into a large-sized light source for use, facilitating production and maintenance; and multiple driving chips are used for simultaneous driving, and each small lamp panel can be adjusted independently, achieving good uniformity of the light sources. Split-type lenses achieve simple production and low cost, and are used in a tiling manner so as to be applicable to photocuring 3D printers of different sizes. Optical lenses are used for shaping light rays, so as to obtain a photocuring 3D printer which has good collimated light rays and a small angle, and is compatible with both a color screen and a black-and-white screen.
