A Network Control System for Scene Adaptive Semiconductor Lighting

This paper presents a design for intelligent control system of scene adaptive semiconductor lighting. The new design contains the host computer and the terminal in a control network. The lighting effect patterns are edited by the software on the host computer, then the lighting scene data is transported to the terminal through network. The terminal is a sub-controller based on the embedded system which is consisting of the ARM920T architecture processor and FPGA programmable logic devices, to control the lighting effects of LEDs carried on it with DMX512 signal to realize digital light regulating. The control system can be applied to many kinds of semiconductor landscape lighting, such as the surfaces of buildings and indoor hall spaces, while it can realize remote scenery setting and LED screen real-time playing through combination with the lighting effects editing software in the host computer. It will contribute to the lighting control in the future.
