本文对恒定和变动照明两种设计进行了实验性观察。恒定照明为工作场所300lx照度,调查了3～5个班;为选择无窗房间最有效照明方式,变动照明安排两种类型,调查3～4个班,①种是在8小时期间的照度最初2小时200lx,之后4小时300lx,再后2小时500lx,②种是连续2、2、2、2小时照度分别为200、300、500、300lx。视觉作业能力等观察指标原有水平以开始工作
In this paper, two kinds of constant and variable lighting design were observed experimentally. Constant lighting for the workplace 300lx illumination, surveyed 3 to 5 classes; to choose the most efficient room without window lighting, lighting arrangements for the two types of changes, the investigation of 3 to 4 classes, ① species is the illumination in the first 8 hours 2 hours 200lx, then 4 hours 300lx, then 2 hours 500lx, ② species is continuous 2,2,2,2 hours illumination were 200,300,500,300 lx.
