随着现代化生产规模不断扩大和人们生活水平不断提高,电能供需矛盾日益突出,节电呼声日益高涨。通过分析目前住宅公共照明情况和存在的问题及LED灯的特点,提出了采用自感应式LED灯具替代普通灯具,并通过一个具体例子分析了两者的费效比。 With the continuous expansion of modern production scale and continuous improvement of people’s living standards, the contradiction between supply and demand of electric power has become increasingly prominent, and the call for electricity saving has been on the rise. By analyzing the current situation of residential public lighting and existing problems and the characteristics of LED lamps, a self-induction LED lamp is proposed to replace ordinary lamps, and the cost-effectiveness ratio of the two is analyzed through a concrete example.
