Abstract

We propose a molecular dynamics method dot generation scheme incorporating the periodic boundary and fixed-cell boundary geometrical conditions to generate random dot distribution on the order of several million dots for use in the base of a thin light guide. In addition, the generation scheme can be used to easily adjust the dot density at any local region from illuminance causing feedback in the optical design phase. Based on the incorporation of these two geometrical conditions, the generation of the random dots for the whole LED light guide can be simplified to just three subdomains, one domain represented by the periodic boundary condition, and the other two domains represented by the fixed-cell boundary condition. Employing these conditions significantly shortens the computational time necessary to obtain optimal random dot distribution and subsequent optical optimization on a PC using optical commercial software.
