White light led spectrum acquisition method suitable for painting color protection lighting

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 white light LED spectrum acquisition method that minimizes damage to the color of painting illumination in the exhibition lighting of museums and art galleries. Background technique [0002] Traditional Chinese painting is an artistic treasure of the Chinese nation and an important part of 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, a huge stock. At the same time, a large number of national treasure-level painting treasures have been preserved for thousands of years, with extremely high artistic and cultural value. [0003] The optical radiation in the light source is an important factor causing damage to the exhibits. Therefore, the quality of the artificial light environment is an important technica...

Problems solved by technology

[0019] 2. Propose an analysis and evaluation method to quantitatively evaluate the influence of different wavelengths of monochromatic light on painting colors based on the decay of color parameter values ​​in traditional Chinese paintings, so as to solve the problem that the influence of monochromatic light on the color of traditional Chinese paintings cannot be accurately evaluated at present question
