Innovation Solution
The use of VIVID lighting with a more negative D uv value in addition to existing VIVID lighting and conventional white LED lighting to maintain a consistent color appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If VIVID lighting with greatly negative D uv is used to illuminate display items, then color saturation and visual impact are improved, but the space appears pale pinkish and incongruous when adjacent to conventionally lit spaces
Solution Approach 1:
The illumination system is divided into multiple light sources with different D uv characteristics. Some light sources provide VIVID lighting with greatly negative D uv for color saturation, while other light sources provide compensation lighting with less negative or positive D uv values. This segmentation allows each light source to perform its specialized function while the combined effect resolves the color incongruity problem.
Solution Approach 2:
The system changes the D uv parameter of different light sources to achieve the desired effect. By controlling some light sources to have greatly negative D uv values and others to have less negative or positive D uv values, the system maintains both color saturation and natural appearance. The compensation lighting sources effectively adjust the overall D uv parameter of the illumination environment.
2Manufacturing precision
If only VIVID lighting with greatly negative D uv is used in a space, then display items achieve enhanced color appearance, but the overall space color temperature shifts toward pale pinkish
Solution Approach 1:
The compensation lighting sources act as a counterweight to the VIVID lighting sources. While VIVID sources strongly influence color saturation with greatly negative D uv values, the compensation sources with less negative or positive D uv values counterbalance this effect. This counterweight approach prevents excessive color temperature shift while preserving the color rendering benefits of VIVID lighting.
Solution Approach 2:
The illumination system uses a composite approach by combining multiple light sources with different spectral characteristics. Rather than using a single light source type, the system integrates VIVID lighting sources and compensation lighting sources to create a composite illumination environment that achieves both color accuracy and natural color temperature.
3Manufacturing precision
If VIVID lighting with greatly negative D uv is used adjacent to conventional white LED lighting, then display items in the VIVID space achieve enhanced color saturation, but the boundary between spaces shows noticeable color discontinuity
Solution Approach 1:
The compensation lighting sources function as intermediaries between the VIVID lighting sources and the conventional lighting in adjacent spaces. These intermediate light sources with moderate D uv values create a transition zone that smooths the color gradient at space boundaries, reducing noticeable discontinuities while allowing the VIVID lighting to maintain its color saturation benefits.
