SAW-TEETH SHAPE PROCESSING DEVICE FOR A LIGHT ENTRANCE OF A LIGHT GUIDE PANEL USING A LASER, CAPABLE OF DIFFERENTLY FORMING THE ANGLES OF THE SAWTEETH SHAPES FROM ONE ANOTHER BY IRRADIATING A LASER BEAM FOCUSED ON ONE SIDE OF THE LIGHT GUIDE PANEL

摘要

PURPOSE: A saw-teeth shape processing device for a light entrance of a light guide panel using a laser is provided to uniformly disperse a light, which is emitted to the saw-teeth shapes of the light entrance of the light guide panel from an LED(Light Emitting Diode) light source, inside the light guide panel.;CONSTITUTION: A saw-teeth shape processing device for a light entrance of a light guide panel(210) using a laser includes a laser oscillating part for processing the saw-teeth shapes of the light entrance of the light guide panel by irradiating a laser beam to one side of the light guide panel. The laser oscillating part irradiates the laser beam with a Z-axis rotary motion and a Z-direction linear motion on an X-Y plane, so that the direction of the light which is emitted from a light source at the one side of the light guide panel can be matched with the direction of each vertex of the saw-tooth shape of the light guide panel to be processed in order to form the saw-teeth shapes on the light entrance of the light guide panel. The laser oscillating part includes the laser, which generates the laser beam, and a laser irradiating part, which irradiates the laser beam to the light guide panel. The Z-axis rotary motion and linear motion of the laser irradiating part is implemented on the X-Y plane. The cross sections of the saw-teeth shapes of the light entrance of the light guide panel is a triangle or a half circle.;COPYRIGHT KIPO 2013
