The design of this new concept street lamp, use the theory of raindrop-potential energy converter. A magnet is fixed under the coil in a board. When the rain occurs, the raindrop taps the board and makes it vibrate. So the coil moves in the magnetic field and produce electricity. The coil can output stable electricity by connecting a regulator. Moreover, the top of the lamp is funnel shaped. It can collect the raindrops. Through the filtering system, the raindrops can be second time used to wash the road surface or irrigate the pasture. This design greatly decreases the waste of water and use the water source immediately when it rains.
