초록

유물에 대한 조명의 변색 영향을 파악하기 위해서는 유물을 구성하는 재질에 대한 빛의 반응특성을 우선 분석하여야 한다. 본 연구에서는 회화유물의 채색층을 구성하는 대표적인 전색제인 동물성 아교와 린시드유를 대상으로 하였으며, 파장 특성이 다른 White LED와 Blue LED 조명을 사용한 가속열화실험을 통해 변색 영향 정도를 확인하였다. 실험 결과, 동물성 아교 및 린시드유는 Blue LED 조명을 사용한 가속열화실험 조건에서 변색이 두드러지게 나타났으며, 두 종류의 LED 조명 중에서 전복사속(mW) 값이 큰 Blue LED에서 재질 변색 정도가 크게 나타났다. 이상의 결과로, 동물성 아교 및 린시드유 등 회화유물 전색제의 변색에 미치는 광원의 영향은 전광선속(lm)보다 전복사속(mW)이 주요하게 작용함을 파악하였다.

In order to understand the influence of light artifact discoloration, priority must be given to the reaction characteristics of the light the materials constituting the product. In this study, we focus on two representative medium, animal glue and linseed oil which constitute the colored layer of the painting relics. This study is based on an accelerated degradation test using two types of light emitting diods (LEDs) with different wavelength characteristics. In the experiments, discoloration appeared markedly in the animal glue and linseed oil under accelerated aging test conditions using Blue LED. Among the two types of LEDs, the degree of discoloration of the material was much higher with the Blue LED having the total radiation flux (mW). This indicates that the discoloration of painting artifacts such as animal glue and linseed oil is more significantly influenced by the total radiation flux (mW) of the light source than the total luminous flux (lm).
