Abstract
It is difficult to describe the luminous intensity distribution (LID) of louver lighting analytically because the louver is composed of a lot of reflection sides which reflect each other. A widely used luminaire, twin fluorescent lamp with louver, is modeled and the influence of louver shape on LID is studied and investigated by means of the Monte Carlo (MC) simulation method. The theoretical analysis and research results show that the surface reflectance, pitch size, and depth of louver have a great influence on LID and the effect of lighting. A verification test done in a model room shows that the simulation results agree with the measured data well. This paper supplies a new way for the research and optimum design of louver lighting.
