System and method for producing and/or using semi-transparent corrugated structures which automatically change their transparency to the Sun's rays during the hours of the day, and the resulting structures

摘要

Corrugated transparent or semi-transparent structures, typically from Polycarbonate or Acrylic, are typically used for creating for example various transparent or semi-transparent walls or roofs for example in large buildings or for creating greenhouses for plants. However, especially for example during the summer, this can cause overheating of the greenhouse effect, so that too much heat is caught inside, which can have undesirable effects. The present invention shows a very cheap solution for automatically regulating the penetration of the Sun's rays through such structures during the day, so that for example at noon the Sun's penetration is automatically lowered. This is preferably achieved by using a sandwich in which two external transparent plates are connected by non-transparent or at least less transparent inner walls (also called bridges) and using appropriate orientations so that when the sun rises or sets the Sun's rays can easily enter more directly and when the sun rises at noon the non-transparent or less transparent inner bridges block direct light from the Sun.
