Planar film construction for airports, has several perforations occupying specific area to transmit light separated by land area that reflects specific amount of incident light

摘要

The construction (30) has an intermediate layer (34) arranged between a color layer (32) and an adhesive layer (36), and several perforations occupying 10-35% of the construction. About 50% of normal incident light is reflected by the land area, at adhesive layer separating the perforations and remaining light is transmitted through the perforations.
