| Abstract: | The basic principle of LED-SL based on UV-LED light is introduced.For the feature of UV-LED light,the effect of the beam divergence angle is developed on the shape of resin SL.Based on Jacobs' SL principle,a mathematic model of divergence beam SL single line is set up.The single line shape differece and its effect of different light sources,such as UV-LED,laser and Hg light,are analyzed and comporred.The high accuracy,high efficiency and low cost advantages of LED-SL system were embodied in the comparisons. |
