摘要
大尺度媒体立面作为新的照明方式在各级城市中广泛建设,因建设周期、建设主体、灯具参数等因素导致大尺度画面普遍存在光色偏差,影响景观照明整体联动的效果。本文初步分析光色差异产生的原因与主要影响因素,建议在项目流程不同阶段进行控制;对于不可避免的光色偏差,从基色光和混合光两个角度构建光色偏差校正理论模型,初步实现在相同的控制系统指令下,不同灯具呈现相同的光色和亮度。光色偏差校正理论的模型技术复杂、难度较大,但符合当前数据时代的技术路线,在智慧城市或数字孪生的照明领域会逐渐得到广泛应用。
As a new lighting method,large-scale media facade is widely constructed in many cities.Due to the construction period,construction subjects,lighting parameters and other factors,the color deviation is common,which affects the unified dynamic effect of large-scale media facade.This study preliminarily analyzes the causes and main factors of light-color difference and suggests to get it under control at different stages of the project process.For the inevitable light color deviation,the theoretical model of light color deviation correction is constructed from primary lights and mixed lights perspectives,which is preliminarily realized that different lamps show the same color and brightness under the same instructions of a control system.The theoretical model of light color deviation correction is complicated and difficult,however,it is in line with the technical route of DT,and will gradually be widely used in the lighting technology of smart city or digital twin.
