现在的路灯都是使用电厂发出来的电进行照明的,每年不仅浪费许许多多的电能,也给国家浪费许多钱。我想,如果有一种太阳能路灯就好了。这种路灯安装上太阳能转换装置,能将白天的太阳能聚集起来,储存在“能量储蓄器”里。到夜晚,路灯就会自动亮起来,到了第二天太阳一出来就会自动熄灭。如果碰到阴雨天,也没关系,能量储蓄器中的多余能量仍旧可以使路灯在晚上亮起来。
Current street lights are all powered by electricity from the power plants, not only wasting a lot of energy each year but also wasting a lot of money for the country. I think if there is a solar streetlight just fine. This kind of street lamp is installed with solar energy conversion device, which can gather the daytime solar energy and store it in “energy storage device”. By night, the street light will automatically light up, and the next day the sun will go out automatically. If you encounter rainy days, it does not matter, the excess energy in the energy storage device still lights can make the street light at night.
