Light module is made up of light guide plate, expelling plate, light source.
Light guide panel material mainly has optics acryl, Merlon, styrol copolymer, cyclic olefin polymer, with optics
Acrylic is base material, and on side illuminator is loaded onto, using the high light line in back light model setting technology in sheet material bottom surface light guiding points after energization
Conductivity, when making the illumination through light guide plate be mapped to each light guiding points, reflected light can be to different angular spreads, to destroy transmitting bar
Part and projected by light guide plate front, the light guiding points that light guide plate is mainly differed by various densitys, size, and reflected into by various
Area source, the whole plane of acrylic plate will send bright, uniform, soft light, and the effect of sheet emitting is that back light is anti-
It is emitted back towards in light guide plate, to improve efficiency of light.
Preparation method in conventional light guiding plate mainly has three kinds：Screen printing ink, injection and laser engraving.Silk
Wire mark brush has little, relatively wide to sheet material applicability equipment investment, production efficiency height, is suitable for the excellent of single product production in enormous quantities
Gesture, but, serigraphy exist many auxiliary material input big, complex manufacturing technology, time-consuming, quality control link, fraction defective height,
Luminous efficiency be not easy lifted, Luminescence Uniformity be difficult adjustment, easily occur xanthochromia, ink easily come off and turn to be yellow, light decay it is tight
