博物館展廳和文物庫房中的采光，通常用三種光源——日光燈、白熾燈和射燈。書畫藏品在光的直接照射下，都會受到不同程度的損害。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.
光線對書畫的影響有三方面：
The influence of light on calligraphy and painting has three aspects:
光輻射熱；
Light radiation heat;
光氧化；
Photooxidation;
光能的破壞作用。
The destructive effect of light energy.
1、光具有能量當其向外輻射時會產生熱效應。可見光與紅外線熱效應大，稱為熱射線。光輻射熱對棉、紙等植物纖維素材料的耐久性產生影響，使藏品局部溫度升高，濕度下降，使纖維素聚合度降低，機械強度下降。進而導致紙張、紡織品等材料彈性減弱、變脆，書畫中的紙張變黃、顏料變色、粉化剝落等。
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、聚合物在含氧環境中，受到光的作用會產生光氧化反應，而引起聚合物的斷鏈紙張中的纖維素發生光氧化反應時，生成易粉碎的氧化纖維，使強度和耐久性降低，字跡、顏料等在光氧化作用下也會產生褪色現象。
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.lebigueone.com Look!
