PROJECTION IMAGING FILM FOR GLASS CURTAIN WALL OF BUILDING

摘要

A projection imaging film for a glass curtain wall of a building. The projection imaging film comprises a base film layer, a plurality of light transmitting elements is arrayed on the base film layer, a plurality of reflecting elements is further arrayed on the base film layer, and the light transmitting elements and the reflecting elements are mutually spaced. With the plurality of light transmitting elements and the plurality of reflecting elements arrayed on the base film layer and mutually spaced, the light transmitting elements can transmit light, so that the normal illumination intensity inside a building can be kept; and the reflecting elements can reflect projection light, so that the projection quality of a glass curtain wall of the building is improved.
