建筑景观照明设计中光源光谱与环境作用的关系

景观照明设计师一般从实践中理解所设计环境要素,而相对缺乏对光源光谱以及景观形成的深刻理解,从而导致不能预期景观照明最终带来的效果,目前景观照明中存在照明情境不符、过度照明、光污染等问题。通过从光谱理论的角度探讨光源色与物体色的关系,以及光谱与物体反射的作用理论,并以某一物体色样作为参考,探讨了传统光源、LED光源以及各种单色光谱对于色样照射产生的效果,分析了光源光谱与环境作用关系,得到景观照明效果的一般性结论。由此可以从理论上对建筑照明设计中照明效果进行预期以及选用合适光谱的光源。基于光谱理论的推导、计算,使得景观照明效果能够完全定量化。

Theoretic Analysis on Effect of Light Sources' Spectrum on Environment in Architecture Landscape Lighting

Generally, lighting designs originated from designer＇s experience, and the lack of understanding spectrum and landscape formation results in unexpected effect, like discrepancies of lighting and landscape, excessive lighting, light pollution, etc. Based on spectrum theory, relationship between illuminant color and object color had been discussed, and through taking an object color sample as a reference, lighting effect of traditional light sources, LED light source and a variety of monochromatic spectrum light sources had been studied. Effect of light sources＇ spectrum on environment had been analyzedand, general rules of landscape lighting effect are achieved. The results make it possible to theoretically predict architectural lighting design effect in the design procedure and help to choose appropriate light spectrum. Based on spectrum theory, landscape lighting effects can be fully quantified.
