Active diffusing light pipes (such as hollow tubular lighting) are means of directing and diffusion light (daylight or electrical light) into interior spaces. The two principal objectives of this paper are : 1) to show the development of an advanced new light pipe simulation model and 2) to compare this optical model with another Visual Ergonomics lighting simulation model. The optical model of a diffusing light pipe was realized for the facility of the simulation using the Apilux software. This optical model is created by reflective mirrors with variable transparence. The Apilux optical model are designed from the analytical models of efficiency calculation (see section 1). The Visual Ergonomics lighting model are designed by starting from measurement results (photometrical characterization of a diffusing light pipe).
