    Optimized pattern design of a light guide using 2D ray-tracing simulation
    (SPIE, 2023) Medrano Gurrea, Mario; Jiménez Martínez, Unai; Tainta Ausejo, Santiago; Erro Betrán, María José; Arnedo Gil, Israel; Beato López, Juan Jesús; Izura, J.; Zabala, S.; Institute of Smart Cities - ISC
    We propose the use of a simplified model for the analysis of the scattering elements used in edge-lit systems. By modelling their behaviour as lambertian light sources whose properties depend on the size and geometry of the scatterer and LGP, it is possible to simulate the illuminance map of the edge-lit structure using only 2D ray-traced simulation. This reduces the computational complexity in the optimisation process used to calculate the scatterers distribution to achieve maximum uniformity in light extraction. The results obtained by comparison between the proposed algorithm and a commercial software demonstrate the validity of the proposal.
