陕西省血液中心LED节能灯具改造分析

Analysis of LED light illumination upgrading in Shaanxi Blood Center

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;9W节能灯更换为4WLED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。

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.
