High color rendering multi-spectral LED light source, exhibition lighting lamps for museum exhibits, exhibition arrangement and lighting methods

Abstract

The invention provides a high-color-rendering multi-spectrum LED light source, which includes an LED light source chip, a light source mounting substrate, and an LED driving module. There are dozens of different LED light source chips in the multi-spectral LED light source of the present invention, each LED light source chip has different spectral wavelengths and spectral bandwidths, and the LED drive module is provided with a power supply module, a microprocessor module, and multiplex separation module, computer interface module. The invention also provides an exhibition illuminating lamp for museum exhibits and a method for arranging and illuminating them. The invention not only has high color rendering, but also has the characteristics of avoiding the sensitive spectrum of cultural relics exhibits, can avoid or reduce the photooxidation suffered during the exhibition, and can achieve accurate detection through independent spectrum driving technology, multi-spectral light source testing and automatic control system. The precise control of the light intensity of different bands in the lighting source can meet the needs of different cultural relics, and can reduce the impact of the light source on the cultural relics while ensuring the color rendering of the light source to fully display the cultural relics exhibits.

Description

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

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.
