Light source assembly and 3d printer

Abstract

A first light transmitting assembly mainly uniformizes light, and a second light transmitting assembly mainly collimates the light, such that the light projected to a display screen can accurately cure resin. A light source assembly includes a light emitting assembly, the first light transmitting assembly and the second light transmitting assembly. The light emitting assembly and the second light transmitting assembly are arranged on two opposite sides of the first light transmitting assembly respectively, and an outer profile of the second light transmitting assembly is of a cambered plate-like structure. Light emitted by the light emitting assembly is projected after being sequentially refracted by the first light transmitting assembly and the second light transmitting assembly. The light source assembly is mainly used for providing backlight for 3D printing.
