Abstract: A scanning light source module for providing a pattern beam to a target object on a work plane is provided. The scanning light source module includes a light emitting device for providing a beam, a beam reducing/expanding device for adjusting an outer diameter of the beam, a shaping lens set for converting the beam into a pattern beam, a scanning reflective mirror set for reflecting the pattern beam to move along at least one direction, and a telecentric flat-field focusing element having an incident surface. The pattern beam has multiple parts. There is a spacing between the parts. The pattern beam is reflected to different positions on the incident surface by the rotation of the scanning reflective mirror set. There is a distance between the work plane and a focal plane of the telecentric flat-field focusing element.

Abstract: A light emitting method includes passing a laser beam through at least one offset assembly and a focusing assembly in sequence, and actuating, by a control-manipulating mechanism, the offset assembly to cause the laser beam to be offset, so that the laser beam can quickly produce a controllable opening of any shape in a drilling process.
