â€œHey, this street lamp will have a 'conch' that will turn around.â€ â€œThere is a solar cell below!â€ Recently, a new scene was added to the marina of the Bishuiwan Port in Zhangzhou City on the southern bank of Hengshui Lake. The street lights are particularly eye-catching.
It was learned from the Ganzhou Municipal Science and Technology Bureau that this is a new energy-saving complementary lighting street lamp newly developed in the city. It uses the effective combination of wind energy and solar energy to maximize the use of natural energy for lighting. (Reporter: Guo Wei, Correspondent: Yang Wanning, Editor: Guo Kai)
