Prismatic film offer advantages such as the possibility of transmit light effectively in lighting applicationswith the benefit of reducing energy consumption. This paper presents several developments based on theircharacteristics which allow direct light suitably in several fields as architecture, road and automotivelighting and signaling. A mathematical model is presented to provide a quantitative estimation of theinfluence of numerous factors that affect the transport of light in order to easily predict light extractionwhile avoiding heavy software calculations. The deformation produced in a prismatic film induced bychanges in the curvature of the cylindrical guide is characterized by image analysis. This method shows therelationship between the curvature of the film, the deformation and the flux of transmitted light.
