Seeing and perception 看见和感知
我们获取周边世界信息的主要途径是通过我们的眼睛。光不仅是基本的先决条件，它也是我们能看见的中间媒介。根据它的强度、分布方式和属性，光创造出特定的环境条件，这个环境条件影响着我们的感知。照明设计实际上是对我们视觉环境的规划。好的照明设计旨在创造感性的条件，使我们能够有效地工作，并使自己处于安全的状态，同时促进在特定环境中的幸福感。同时它从美感的角度强化环境。照明状况的物理量是可以计算和测量的。最终决定照明概念是否成功的，是照明对空间的使用者和对他的主观感知产生的影响。
The majority of the information that we receive about the world around us comes through our eyes. Light is not only an essential prerequisite, it is the medium by which we are able to see. Through its intensity, the way it is distributed and through its properties, light creates specific conditions which can influence our perception. Lighting design is, in fact, the planning of our visual environment. Good lighting design aims to create perceptual conditions which allow us to work effectively and orient ourselves safely while promoting a feeling of well-being in a particular environment. At the same time it enhances the environment in an aesthetic sense. The physical qualities of a lighting situation can be calculated and measured. Ultimately, it is the actual effect the lighting has on the user of a space and his subjective perception, that decides whether a lighting concept is successful or not.
