Example Embodiment

[0086] 1. Model test piece production

[0087] (1) According to Chinese traditional techniques and crafts, four organic pigments, cyan (cyan), garcinia (yellow), rouge (red), and pine ink (black) are used, as well as azurite (cyan), orpiment (yellow), Five inorganic pigments, cinnabar (red), clam powder (white), and graphite (black), draw the color of the specimen.

[0088] (2) Using rice paper and silk to make the test piece substrate.

[0089] (3) The paste made of wheat starch is manually mounted in accordance with classical techniques.

[0090] 2. Preparation of experimental light source

[0091] (1) Using a 150W halogen tungsten lamp, 482nm, 510nm, 583nm, 650nm narrow band filters and infrared filters, the four main monochromatic light sources constituting the WLED spectrum are made. At the same time, a spectrophotometer is used to detect the spectrum of the monochromatic light source to ensure the accuracy of the experiment and obtain the SPD of the monochromatic light source.

Abstract

The invention belongs to the field of protective lighting for cultural relic, and provides a white LED spectrum acquiring method applicable to drawing color protective lighting. By the aid of the white LED spectrum acquiring method, problems of deficiency of scientific experiment WLED (white light emitting diode) spectrum acquiring methods with the lowermost color damage and incapability of accurately evaluating influence of monochromatic light on color conditions of the traditional Chinese drawing at present can be solved. The technical scheme includes that the white LED spectrum acquiring method applicable to drawing color protective lighting comprises steps of 1), manufacturing model test specimens; 2), preparing experiment light sources; 3), carrying out illumination experiment processes, to be more specific, (1) carrying out experiments in all-dark optical laboratories, (2) placing the drawing test specimens under the light sources and perpendicularly illuminating the test specimens by the aid of the light sources and (3) periodically illuminating the color test specimens; 4), carrying out parameter detection processes. The white LED spectrum acquiring method has the advantage that the white LED spectrum acquiring method is mainly applied to design and manufacture places.

Description

Technical field [0001] The invention belongs to the field of protective lighting for cultural relics, and in particular relates to a method for acquiring white light LED spectrum with minimal damage to painting illumination and color in exhibition lighting of museums and art galleries. Background technique [0002] Traditional Chinese painting is the artistic treasure of the Chinese nation and an important part of the world cultural heritage. At present, there are 3,993 historical and art museums in my country that preserve painting exhibits, including more than 640,000 traditional painting collections, with a huge stock. At the same time, a large number of national treasure-level painting treasures have been preserved for thousands of years, which have extremely high artistic and cultural value. [0003] The optical radiation in the light source is an important factor that causes damage to the exhibits. Therefore, the quality of the artificial light environment is an important te...
