Abstract

The invention provides a high-color rendering property multispectral LED light source, which comprises an LED light source chip, a light source installation substrate and an LED drive module. The multispectral LED light source is provided with dozens of different LED light source chips; each LED light source chip has different spectral wavelength and spectral bandwidth; and the LED drive module is provided with a power supply module, a microprocessor module, a multichannel separation module and a computer interface module. The invention further provides an exhibition lighting lamp of museum exhibits and an exhibits arrangement and lighting method. The high-color rendering property multispectral LED light source has the characteristics that the multispectral LED light source has high color rendering property and sensitive spectrums of cultural relics exhibits are avoided; the photo-oxidation action in exhibition can be avoided or reduced; precision control on light intensity of different bands in a lighting source can be achieved through a spectral independent drive technology and a multispectral light source test and automatic control system; the high-color rendering property multispectral LED light source adapts to the requirements of different cultural relics; the influence of the light source on the cultural relics is reduced while the color rendering property of the light source is ensured and the cultural relics exhibits are fully displayed.

Description

technical field [0001] The invention relates to a high-color-rendering multi-spectrum LED light source, in particular to an LED multi-spectrum lighting source for illumination of light-sensitive cultural relics, and an exhibition arrangement and lighting method for museum exhibits. [0002] The color rendering ability of the light source to the object is called color rendering, which is compared with the appearance color of the object under the reference or reference light source of the same color temperature. The spectral content emitted by the light determines the light color of the light source, but the same light color can be composed of many, few or even only two monochromatic light waves, and the color rendering of each color is also very different. Light sources with the same light color will have different spectral compositions, and light sources with wider spectral composition may provide better color rendering quality. When there is little or no main wave reflected ...

AI Technical Summary

Problems solved by technology

[0009] Although relevant studies have given the spectral sensitivity bands of cultural relics, the current lighting sources cannot be used for cultural relics of specific materials. They can not only achieve better lighting effects and color rendering of light sources to meet the needs of museum cultural relics exhibitions, but also reduce fragility. The photoaging of cultural relics achieves the purpose of protecting cultural relics

[0010] For example, although the conventional RGB mixed-light LED light source can adjust the output energy of red light, green light, and blue light, excessive reduction of one component in RGB will cause a significant decrease in color rendering index, which will seriously affect the display effect

Moreover, the RGB-LED light source itself has some energy output in ultraviolet and infrared, which is not conducive to the protection of cultural relics; the color rendering index of the RGB-LED light source itself is generally below 80, which cannot meet the lighting needs of cultural relics color restoration; Synthesize the spectral types of light sources such as halogen lamps, and it is difficult to adjust the spectral characteristics for different types of cultural relics

[0011] Therefore, the current LED light source still cannot replace the halogen lamp as cultural relic lighting, but can only be used as daily lighting in the exhibition hall. For different cultural relics, there is no exhibition lighting that takes into account the protection of cultural relics and the needs of exhibitions.
