A lighting system which consists of a 32×32×RGB LED matrix and an 8×8 Fresnel lens array is proposed and demonstrated. It accomplishes a localized lighting with 4×4 addressable regions for power saving. It projects colorful patterns on the ground or a wall for atmosphere heightening. Device parameters were studied and optimized taking account of power saving and lighting effect.
