Exhibits protection in light environment design of Art gallery

Light displays a vital role in the exhibition environment especially in Art gallery. Illumination, show of the exhibits´ colour & details, and atmosphere creation can´t work without light. But both natural light and artificial light do harm to the exhibits, which will reduce the strength of the paint and material, even cause the paint fading and paper curl. The damage can´t be recovered , and the exhibits will not exist anymore if the light design is ignored. So the relationship between the exhibits protection and the art visual will become one of the core issues of Art gallery design research.
