滿足電量限制之DALI智慧型燈光情境控制系統

Abstract

燈光控制中最重要的兩個目標就是情境亮度需求與節約能源，在本文中，基於DALI 燈控協定於室內環境提出了一個智慧型燈光控制系統。燈控演算法會在燈具開啟時同時也考慮到電量限制，在滿足電量限制下，盡量達到情境亮度的需求。此外，燈控系統也能隨著室內環境光源的亮度動態調整燈具亮度。而DALI 是近年新興的燈控協定，透過DALI 可以獨立設址的優點，讓我們的系統可以更方便於燈具的控制，同時也減少了佈建的成本。

Scene illumination preference and energy conservation are two major issues in the field of light control. In this paper, we propose and implement an intelligent light control system based on DALI-based approach for indoor scenes. A decision algorithm is designed to determine the proper illuminations of lighting devices to satisfy the desired scene illumination preference and the power constraint at the same time. Additionally, our system can dynamically adjust proper illuminations of devices according to changes of natural light. Benefit from exploiting individual controllability of the DALI lighting systems, we can realize various lighting configurations for desired scene and power constraint without any physical rewiring and training and thus lower cost.
