The invention discloses a water surface advertisement projection device, comprising an emission source and a
refraction projection device, wherein the emission source and the
refraction projection device are arranged in a box, and the emission source comprises an LED high-frequency flashing bar, an advertisement storage
database and an intelligent
processing circuit board , the intelligent
processing circuit board reads the content of the advertisement storage
database, drives the LED high-frequency flashing bar to perform high-frequency flashing according to the content of the advertisement storage
database, and then projects it onto the polygonal lens through the concentrating plate, and the polygonal lens is reflected to the water surface. superior. The device refracts the dynamic image of the advertisement on the
oil film on the water surface through the high-speed rotation of the polygonal lens, so that the advertisement image is more clearly presented in front of people's eyes, which not only saves users a lot of advertising costs, but also helps users avoid A lot of propaganda paper saves resources and protects the environment.
