陕西省血液中心LED节能灯具改造分析

目的:为降低中心血站照明能耗,对隔栅灯具及其他传统灯具进行改造,并保证相同或相近的照度.方法:选择更换不同功率的LED节能灯,并用功率分析仪对改造前后的灯具功率分别进行测试.结果:改造后各种灯具节电50.01%~76.75%,其中60×60格栅灯改造更换成LED节能灯后,节电达76.75%,是所有灯具改造中最高的;9 W节能灯更换为4 W LED节能灯后,节电50.01%,是所有改造中最低的;平均电费降低65.46%.本次灯具改造共花费12.1108万元,改造后每年节约电费15.44万元,不到10个月收回全部改造成本,并得到政府节能专项补助5万元.结论:LED节能灯照明效果较好,质量可靠,改造后节电效果显著

Analysis of LED light illumination upgrading in Shaanxi Blood Center

Objective： To reduce the energy consumption of lighting units. Methods： We replaced the grille lamps and other conventional lighting with LED lights, and compared the results by using a power analyzer. Results： The use of LED lighting had remarkable advantages： -the energy efficiency rate of replaced lighting ranges between 50.01% - 76.75%; -the maximum energy efficiency rate of replaced lighting is 76.75%;the minimum energy efficiency rate of replaced lighting is 50.0%;-the average cost of electricity was reduced by 65.46%：- the cost of refurbishment was 12,1108.00 RMB; - 154,400.00 RMB could be savedannually on the electricity bill by using the converted lighting;- the full cost of refurbishment will be recovered within 10 months. Conclusion： LED lighting has higher quality, is more efficient, and enables remarkable energy savings.
