Abstract To implement glareless and pleasant indoor luminous environment, this study analyze the unified glare rating (UGR), average illuminance and uniformity ratio of illuminance with installation depth and angle of LED flat panel luminaires using AGI 32 lighting simulation software. According to simulation results, maintaining average illuminance, the UGR and uniformity ratio of illuminance were significantly decreased, when the installation angle was changed. On the contrary, maintaining uniformity ratio of illuminance, the UGR and average illuminance were significantly decreased, when the installation depth was changed.
