摘要
焦散是一种在自然界中普遍存在的光学现象,在勒·柯布西耶设计的圣皮埃尔教堂中曾得到精彩应用,但其规律和在建筑光线设计中的应用仍待总结。经由光学分析,光线在经过导光棒时以反射的形式传播,据此可得圆柱形导光棒焦散以近似光圆锥形式投射的基本规律,但实际设计中大量导光棒的焦散效果预判则更为复杂。数值模拟和实体模型验证是建筑设计中最常用的研究方法,对于它们在导光棒焦散光线设计上的运用,可以通过光线追踪、几何计算、试样验证、缩尺模型等方法进行。运用这4种方法,以一个项目案例的设计过程为例,探讨并总结了导光棒焦散设计的基本方法和设计中需考虑的影响因素。
Caustics is an optical phenomenon commonly found in nature,brilliantly applied in Le Corbusier's design of the Sainte-Pierre Church,yet its patterns and applications in architectural light design remain to be explored.Through optical analysis,it is found that light propagates in the form of reflection when passing through a light guide rod,and based on this,the basic law that the caustics of a cylindrical light guide rod is projected in the form of an approximate light cone can be obtained.However,predicting the caustics of a large number of light guide rods in practical design is a more complex problem.Numerical simulation and physical model verification are the most commonly used research methods in architectural design.For their application in the design of light guide rod caustics,methods such as ray tracing,geometric calculation,sample verification,and scale modeling can be used.Using these four methods and taking the design process of a project case as an example,this paper discusses and summarizes the basic methods of caustics design and the main factors that should be considered.
