Study on the Improvement of Microprism Retroreflective Material

In this paper, the microprism reflective structure is optimized by theoretical research and simulation calculations, and based on the current technology of V-shaped diamond blade manufacturing mode, an improved microprism retroreflective material is designed. By adjusting the intensity distribution and angle of the light cone, we can control the style of light cone which is formed by the reflected light for optimal reflective effect. The microprism reflective structure contains the positive unit and negative unit. The negative unit relative to the positive unit is rotated 60° for producing phase superposition to reduce the non-uniform of the material orientation. Cutting along a straight line by V-shaped diamond blade, the technology creates a plurality of higher-precision and smaller reflective elements and enhances the retroreflective performance. Meanwhile, the overall processing technology which reduces labor force greatly is beneficial to the cost control and highly practical during the fabrication process.
