LED灯管与直管荧光灯在办公室中的照明效果对比

为了对比LED灯管与直管荧光灯在办公室中的照明效果,选择了14间布灯方式和家具布置均相似的办公室分别安装2种光源进行对比测试,其中4间办公室安装长度为1 200 mm、功率为18 W的LED灯管,另外10间办公室安装长度为1 200 mm、功率为32 W的T8直管荧光灯,经过约300 h的运行后,测量办公桌面的照度,结果表明,用LED照明的办公桌面平均照度比用T8直管荧光灯照明的办公桌面照度高,且采用LED灯管能比采用T8直管荧光灯节能43.75%。

Contrast of Lighting Effect of LEDs and Fluorescent in Office

In order to contrast the lighting effect of LEDs and fluorescent in office,we selected 14 office rooms with similar lamp layout and fitment layout,their lighting source are either LEDs or fluorescent.Among 14 office rooms,there are 4 office rooms’ lighting source are LEDs with 18 W power,and other 10 rooms’ lighting source of fluorescent with 32 W power.When these lamp worked about 300 hours,we measured the illuminance upon the tables in these office rooms,the results indicates that the illuminace upon the tables lighting with LEDs is higher than illuminance upon the tables lighting with fluorescent,and lighting with LEDs will save energy 43.75% than lighting with fluorescent.
