Most of the lighthouses are similar to the shape of a tower, through the lens system on the top of the tower, the light is directed to the sea to illuminate. Modern navigation equipment has been very advanced, and the number of man-operated lighthouses has been greatly reduced. The design idea of this tower comes from California pigeon Point the lighthouse. This tower was built in 1817 and has a special shape and historical significance. Now we will place the tower lamp on the desk as a decoration.
