LED lighting systems that combine lighting capability, emotional and physiological characteristics are required forlighting source and multifunctional applications. In this work, Simulation studies using optical analysis softwarepackages, Light Tools, are presented. This is done to estimate the uniformity ratio of illuminance and photosyntheticphoton flux density (PPFD) of the periodic 2D lattice arrangements, such as square, diamond, two-way biasquadrangular, hexagonal, and Kagome lattices, under the same transmissivity, absorptance and reflectivity. It has beenfound out that the two-dimensional Kagome lattice arrangement exhibited high uniformity ratio of illuminance andPPFD compared to other lattices. Accordingly, these results can be used to guide a design and improve the lightingenvironment which in turn would maximize the uniform distributions of illuminance
