Abstract：Domestic lighting design standards mainly evaluate indoor space brightness based on horizontal illuminance.However,evaluating brightness solely using horizontal illuminance while neglecting the three-dimensional spatial brightness does not accurately reflect the true brightness of the indoor space.For this purpose,Panasonic Corporation and Japanese academic researchers jointly proposed the Spatial Brightness Evaluation Standard(FEU),a new method used to evaluate the three-dimensional spatial brightness of indoor architectural spaces.This paper adopts the FEU evaluation standard and combines it with the"Architectural Lighting Design Standard"(GB 50034-2013).Three different lighting schemes for the three-dimensional spatial brightness of a typical office building lobby were designed and compared.The results indicate that the lighting design for office building lobbies integrates horizontal and vertical lighting methods,creating a visually comfortable three-dimensional spatial lighting environment.Using LED linear ceiling wash lights provides a more uniform lighting effect on the facade,with the Unified Glare Rating(UGR)at lower values,creating a more pleasant and comfortable visual atmosphere in the office building lobby.Adopting a reliable dimming system design for the desired lighting scenes can achieve a lighting energy saving of 52.27%.The lighting design method for three-dimensional spaces is an advanced and modern approach to illuminating office building lobbies,enriching the content of the"Lighting Design"course and enhancing its teaching effectiveness.
