Abstract

This study proposes an effective algorithm that can simulate a lighting environment, especially an LED backlight unit, using the photon mapping method. For higher reliable simulation, we modeled spectral and optical characteristics of LEDs, light sources, and optical sheets. From rendered images, we confirmed that the proposed algorithm can effectively simulate the lighting distribution of LED backlight unit.
