The invention discloses an anti-fouling interactive reflection type landscape decoration light wall which comprises a decoration wall body, a plurality of light-transmitting plates are arranged on the decoration wall body, a plurality of glass sleeves are further arranged on the decoration wall body, a plurality of through holes are formed in the side walls of the glass sleeves, a plurality of magnetic plugs are connected into the glass sleeves in a sliding mode, and the through holes are communicated with the magnetic plugs. An air inlet pipe is installed on the decorative wall, a pulse valve is installed in the air inlet pipe, an elastic corrugated pipe communicated with the air inlet pipe is fixedly arranged at the bottom in the glass sleeve, the upper end of the elastic corrugated pipe is communicated with an air guide pipe, and the upper end of the air guide pipe is sealed. The pulse airflow is injected into the air inlet pipe, the magnetic plug can be pushed to move up and down, then the spiral coil generates current to light the LED lamp beads, meanwhile, the airflow is continuously blown to the light-transmitting plates on the two sides, the lamplight projection decoration effect of the landscape wall can be achieved, meanwhile, dust attached to the light-transmitting plates can be blown away, and the service life of the landscape wall is prolonged. And the light-transmitting plate is kept clean.
