摘要
在民用建筑工程照明设计时,用常规的利用系数计算平均照度和照明功率密度比较繁琐。为便于计算,将光通量、利用系数、维护系数统一成有效光通量;将光效、利用系数、维护系数统一成模糊系数。如已知某类建筑的房间数量、面积,查标准照度和功率密度值,即可由简化计算表中,查出有效光通量和模糊系数,通过简化计算法可算出照度、照明功率密度值。
In civil building engineering lighting design, it is very tedious to use conventional productivity to calculate average illuminance and lighting power density. To make the calculation easy, this paper introduces a method to bring luminous flux, utilization factor and maintenance factor into valid luminous flux, and to bring luminous efficiency, utilization factor and maintenance factor into fuzzy factor. For example, if the room quantity and area of a sort of building is known, find its standard illuminance and power density, then its valid luminous flux and fuzzy factor could be found in that simplified calculation table. Through the simplified calculation method, the illuminance and lighting power density can be calculated.
