00925njm 22002777a 4500 dc García Fernández, Berta author Álvarez Fernández-Balbuena, Antonio author Vázquez Moliní, Daniel author 2019-09-09 Prismatic film offer advantages such as the possibility of transmit light effectively in lighting applications with the benefit of reducing energy consumption. This paper presents several developments based on their characteristics which allow direct light suitably in several fields as architecture, road and automotive lighting and signaling. A mathematical model is presented to provide a quantitative estimation of the influence of numerous factors that affect the transport of light in order to easily predict light extraction while avoiding heavy software calculations. The deformation produced in a prismatic film induced by changes in the curvature of the cylindrical guide is characterized by image analysis. This method shows the relationship between the curvature of the film, the deformation and the flux of transmitted light. 0277-786X 10.1117/12.2529254 https://hdl.handle.net/20.500.14352/13617 https://doi.org/10.1117/12.2529254 https://www.spiedigitallibrary.org/conference-proceedings-of-spie/11120/111200R/Developments-for-lighting-applications-by-using-prismatic-film/10.1117/12.2529254.full Developments for lighting applications by using prismatic film
