Embodiment Construction

[0084] For reaching purpose, the technical scheme that the present invention takes is as follows:

[0085] For the technical solution process, see figure 1 .

[0086] 1. Model test piece

[0087] The model specimens for the experiment were made with Chinese fragile cultural relic pigments, and the types of pigments are shown in Table 2.

[0089]

[0090]

[0091] 2. Experimental light source

[0092] Since the lighting of China's fragile cultural relics requires that the light source should not contain ultraviolet and infrared spectra, 10 typical bands of monochromatic light in the visible spectrum range were selected, and the experimental light source was prepared with LED monochromatic chips. The information of the 10 monochromatic light sources is shown in Table 3, and the SPD is shown in Figure 2.

Abstract

The invention belongs to the interdisciplinary field of cultural relic protection and light source technologies in order to obtain the minimum damage spectrals respectively adopted by different typesof Chinese fragile cultural relic lighting. The invention provides an LED spectral adjustment technology applicable to Chinese fragile cultural relic lighting. The minimum lighting damage for different fragile cultural relics is achieved under the premise of meeting viewing requirements. Therefore, the technical scheme adopted by the invention is that the LED spectral adjustment method applicableto Chinese fragile cultural relic lighting comprises the steps of firstly selecting the most suitable spectral power distribution (SPD) according to material characteristics of an illuminated object,and then inputting the SPD into an LED controller; when the illuminated object is changed, the most suitable SPD is selected according to material characteristics of the new illuminated object, and the spectral is adjusted into the new SPD in the LED controller, thereby achieving the minimum lighting damage for the new illuminated object under the condition of meeting the viewing requirements. TheLED spectral adjustment method is mainly applied to the occasion of cultural relic protection.

Description

technical field [0001] The invention belongs to the interdisciplinary field of cultural relics protection and light source technology, and in particular relates to how to use LED spectrum adjustment technology for highly sensitive Chinese fragile cultural relics such as calligraphy and painting, rare books of ancient books, and colorful paintings of ancient buildings in the lighting of exhibits in museums and other places , On the basis of ensuring the viewing effect, the lowest lighting radiation damage of cultural relics can be realized. Specifically, it involves an LED spectrum adjustment method suitable for the lighting of China's fragile cultural relics. Background technique [0002] The current situation of cultural relics protection is not optimistic. Shan Jixiang, member of the National Committee of the Chinese People's Political Consultative Conference and director of the Palace Museum, pointed out in the proposal of the two sessions: Due to problems in protection,...
