博物馆展厅和文物库房中的采光，通常用三种光源——日光灯、白炽灯和射灯。书画藏品在光的直接照射下，都会受到不同程度的损害。下面

The lighting in museum exhibition halls and cultural relics warehouses usually uses three kinds of light sources - fluorescent lamps, incandescent lamps and spotlights. Calligraphy and painting collections will be damaged to varying degrees under the direct illumination of light. The following is the introduction of celebrities' calligraphy and painting personnel.
光线对书画的影响有三方面：
The influence of light on calligraphy and painting has three aspects:
光辐射热；
Light radiation heat;
光氧化；
Photooxidation;
光能的破坏作用。
The destructive effect of light energy.
1、光具有能量当其向外辐射时会产生热效应。可见光与红外线热效应大，称为热射线。光辐射热对棉、纸等植物纤维素材料的耐久性产生影响，使藏品局部温度升高，湿度下降，使纤维素聚合度降低，机械强度下降。进而导致纸张、纺织品等材料弹性减弱、变脆，书画中的纸张变黄、颜料变色、粉化剥落等。
1. Light has energy. When it radiates outward, it will produce a thermal effect. Visible light and infrared light have large thermal effects, which are called thermal rays. Light radiation heat has an impact on the durability of cotton, paper and other plant cellulose materials, which increases the local temperature of the collection, decreases the humidity, reduces the degree of polymerization of cellulose, and decreases the mechanical strength. This in turn leads to the weakening and embrittlement of the elasticity of paper, textiles and other materials, yellowing of the paper in calligraphy and painting, discoloration of pigments, powdering and peeling, etc.
2、聚合物在含氧环境中，受到光的作用会产生光氧化反应，而引起聚合物的断链纸张中的纤维素发生光氧化反应时，生成易粉碎的氧化纤维，使强度和耐久性降低，字迹、颜料等在光氧化作用下也会产生褪色现象。
2. In the oxygen containing environment, the polymer will produce photooxidation reaction under the action of light. When the cellulose in the broken chain paper of the polymer undergoes photooxidation reaction, it will generate oxidized fibers that are easy to crush, reducing the strength and durability. The handwriting and pigments will also fade under the action of photooxidation.
The influence of light on the storage of calligraphy and painting has three aspects, so here we go. You should pay more attention to this. For more information, please come to our website http://www.jinandayatang.com Look!
