The invention discloses an energy-saving and environment-friendly road lighting device comprises a fixed shell arranged in a foundation, the upper surface of the fixed shell is fixedly connected with a street lamp pole through bolts, the side face of the street lamp pole is provided with an LED lamp and an annular pipe, and the outer surface of the annular pipe is provided with a plurality of air outlet holes. A plurality of grooves are formed in the upper surface of the fixed shell, rubber piston rings are slidably connected to the inner walls of the grooves, and T-shaped pedals are fixedly connected to the upper surfaces of the rubber piston rings. According to the energy-saving and environment-friendly road lighting device, by arranging the T-shaped pedals, the communicating pipe, the rubber piston rings, the power generator and the rotating blades, pedestrians can conveniently tread the T-shaped pedals, the rubber piston rings extrude air in a grooves in the fixed shell and push the air into the communicating pipe in a one-way mode, generated airflow drives the rotating blades to rotate, the power generator generates electric energy, therefore, electric energy is generated only when pedestrians pass by, more energy is saved, and meanwhile air is exhausted through the air outlet holes of the annular pipe to blow away dust and winged insects on the surface of the LED lamp.
