OPTICAL SIMULATION OF LIGHTING BY HOLLOW LIGHT PIPES

摘要

Active diffusing light pipes (such as hollow tubularrnlighting) are means of directing and diffusion lightrn(daylight or electrical light) into interior spaces.rnThe two principal objectives of this paper are : 1) tornshow the development of an advanced new lightrnpipe simulation model and 2) to compare thisrnoptical model with another Visual Ergonomicsrnlighting simulation model.rnThe optical model of a diffusing light pipe wasrnrealized for the facility of the simulation using thernApilux software. This optical model is created byrnreflective mirrors with variable transparence.rnThe Apilux optical model are designed from thernanalytical models of efficiency calculation (seernsection 1).rnThe Visual Ergonomics lighting model arerndesigned by starting from measurement resultsrn(photometrical characterization of a diffusing lightrnpipe).
