Systems for light diffusion through transparent materials: performance indexes related to the containment of luminance and to removal of the UV component
This paper relates the results of some research, the first phase of which has been presented in a CIE Convention in 2002. The subject of the research is the study of the materials usually employed for light diffusion, in particular the commercial and exhibition applications. Altogether, the research involved different types of glass, micro-drilled metal plates, plastic materials and films. The screens have been tested in relation to their performance, in terms of: distribution of surface luminance, energetic power in the visible field, removal of energy in the UV field. The aim of the study is the identification of materials that guarantee a proper distribution of light on the surface, a high performance in the transmission of the light flow and a strong UV removal
