Study on chromatic light reappeared digital technology in architectural lighting environment

With using digital image technology, and in standardizing chromatic display device, the paper framed a mathematical conversion model based on computers and televisions. It put forward a quantitative restituting method of chromatic light for the research work on architectural lighting environment and design in practice. It made lighting scene and designing effect as true as possible restitute in the laboratory, so it can better apply to urban landscape illumination and design even more.
