光可以显现空间，我们在用理性去认识表象空间(即现实空间)你是否知道光也可以用来显现意象空间呢？人们一直以来都专注表象空间的探索，而往往忽略对自己意向空间的开发，所以人判断空间繁简难免局限于表象空间，并以为意识上的空间状态只是表象空间的倒影，意识空间与表象空间被强迫的以一种人为的线性关系联系着。

事实是人们认识空间的同时，意象与表象存在着某种差延(differance)，而这种差延又使我们对空间的认识进入一个新的阶段。正如英国诗人威廉·布莱克（William Blake）所说：“To see a World in a Grain of Sand\And a Heaven in a Wild Flower\Hold Infinity in the palm of your hand\And Eternity in an hour.”

我们所认识的空间涵盖着各种片段性的信息，人对空间的理解就是通过将部分的信息消解出来，从而达到对空间的认知。一个片段信息所衍射出来的意象是非常丰富的，但随着片段信息的不断增加，多种意象相互消减，整体印象反而不明确了。正如无影灯原理，随着光源的不断增加，物体影子却变得越来越模糊，最终达到消影。一般情况下，光无差别的显现空间。美的丑的、需要的不需要的-----这便造成了空间的模糊性。作为设计师，所要做的就是如何利用光来提炼表象空间，引导设计者进入意象空间。

如果把由各种片段信息所组成的表象空间称为第一空间，那么由这些片段信息所衍射出来的意向空间就是第二空间了。由于第一空间与第二空间此消彼长，我们不难对人们传统的空间认识提出质疑。传统的空间理论停留在对第一空间（表象空间）的认知，并认为第一空间的极繁性等同于第二空间(意象空间)的复杂性，但往往第一空间的极简反而能够营造出一个现实所不能达到的丰富的第二空间，而光则是连通第一空间与第二空间的纽带。于是我们认为未来在光的运用上应该更加突出光对第二空间的营造。在第一空间里，物象与光的相遇，即产生光影。光影作为高度概括后的物象，需要观者自己去发掘隐藏的信息并进行再创造。而最终在观者脑中形成的空间便是第二空间。

在中国北部某些地方，由于人们环境保护意识的薄弱，造成土地荒漠化，植物大量灭绝。为了唤起人们对环境保护的重视，我们利用一小块现存的绿地设计了这个反思空间，并命名为——“最终幻想”。建筑环绕小块绿地而建，成圆环形，绿地与建筑之间有延伸到室内的水带相隔。光照下，树影通过水面反射到室内，在室内形成自然意象。与外界几乎隔绝的室内空间却可以透过光影，想象到外界的绿树成荫、清波荡漾、微风徐徐、细雨绵绵------。室内空间的纯粹性增强了意象空间的清晰性。但当参观者由室内到室外时，对外界美好的幻想却被室外荒凉的现状无情打破，意识与现实的强烈落差，人对大自然的美好追忆化作对当前破败不堪的生态现状的深刻反思。

意象一：光照在水面，不管水有多污浊，水影投射到墙上，晃动的光影总是那么清澈透明。

意象二：随风游弋的树影，把观者带进一片绿树葱葱的树林，微风扑面，阵阵清凉。

意想三：墙上的水影随着外界的雨珠荡出阵阵涟漪，把观者带进细雨绵绵中。

Light can visualize space. As we rationally acquainted ourselves with the representation space, we may lose sight of the fact that the light can also visualize the image space. For a long time people have been concentrating on the exploration of representational space while ignoring the image space. As a result, an factitious linear relationship has been set between image space and representation space in a compulsive way, in which space cognition constrained in representation space while image space is only a mirror as to representation space.

But the fact is, when getting to know space, we see a differance between representation space and image space. And it is this differance that leads space cognition to a new phase. As william Blake, a famous British poet, put in his lines: “To see a world in a grain of sand /And a heaven in a wild flower /Hold infinity in the palm of your hand /And eternity in an hour.”

The space we see contains a variety of decodable fragmental information which makes space cognition attainable. As one piece of fragmental information can have abundant images, more information may diminish the images and obscure the overall impression. Like shadowless lamp, with the accumulation of lights, the shadow becomes weaker and weaker and finally disappears. Under normal circumstances, the light visualizing objects, beautiful or ugly, need or not, with no differance that results in the space ambiguity. As an architect, the very job is to utilize the light effect to help people cultivating an image space from representation space.

If we take the representation space containing all kinds of fragmental information as first space, the second space shall be the image space constructed from the decodig of those fragmental information. Through wane and wax intercommunication of the first and sencond space, it is possible to doubt our traditional space cogition, which restricts the research to the stage of first space cognition and takes the complexity of the two as the same. But it is technically the simplicity of the first space that forms a virtual informative second space with the media of light. In this regard we believe that the light application in near future shall highlight the cultivating of the second space under light effect. In first space, the objects and the light work out a highly abstract matter, shadow, through which the observer makes up a second space with imagination.

In North China, We design in a greenery patch an “Final Fantasy” as a introspection space to call people’s consciousness of environmental protection since desertification and extinction of vegetation are mostly due to the ignorance of it. The loop-shaped building centers around the greenery patch to which an extended indoor water stripes attached. With the light effect, the shadows of the trees cast indoors through water reflection and produce a wonderful natural image  with which in the blocked indoor space one can still have an imagination of trees in breezes, ripples and the romantic drizzles. While the simplicity indoor space makes the image in focus, it is significant to point out that in a steep contrast, people may feel frustrated by the gloomy outdoors scenery once they step outdoors. It is this frustration that enables people to find a way in changing the unpleasant outdoor environment as against the pleasant indoor images.

The pleasant indoor images could be as follows:

Image A: Clean and clear fluids on the wall contributes to a clean and clear mood.

Image B: Shadows of leaves fluttering in the kissing of breezes make a carefree and blissful moment.

Image C: Fluids swaying ripple-like in a raining day provides a harmonious picture of people walking in a refreshing indoor drizzle.
