By a historical analysis, I tried to find a system that enables us to understand symbolic meanings in artificial lighting and gives us a higher standard of discernment of the designings of light. In my view such a system is to be devided into the following two sections: a. The substitution of daylight as a symbol of uniformity and selfcontrol expressed by an always available and constant lighting; b. the differentiating lighting as a symbol of power expressed by beams of light and shining things, as a symbol of individuality and of social esteem expressed by selected scources of light and as a symbol of the positive exeption and of starting new.
