A uv index rating indication system and its use
By setting multiple ultraviolet indicator blocks on the substrate surface and using photochromic materials with different concentrations of UV-resistant agents, accurate indication from UV index 1 to 4 is achieved, solving the problem of inaccurate UV level judgment in existing technologies and improving the accuracy and intuitiveness of UV level judgment.

Abstract
本发明涉及紫外线检测技术领域，尤其涉及一种紫外线指数等级指示系统及其应用。本发明包括基底、设置在基底上的紫外线指示层，紫外线指示层包括多个紫外线指示区块，各个紫外线指示区块远离基底一侧表面分别印刷有含不同浓度抗UV剂的光致变色材料；其中，当照射至各个紫外线指示区块表面的紫外线指数等级达到该紫外线指示区块对应的紫外线指数等级时，各个紫外线指示区块表面产生不同的颜色或图案变化，从而实现对照射至各个紫外线指示区块表面的紫外线指数等级的识别。本发明为能够提供直观、精准的紫外线强度参考。
