Laminate structure with embedded cavities and related method of manufacture

An integrated laminate structure adapted for application in the context of solar technology, wafer technology, cooling channels, greenhouse illumination, window illumination, street lighting, traffic lighting, traffic reflectors or security films, said integrated laminate structure comprising at least two elements laminated together such that at least one surface relief pattern of either element has been embedded within the laminate structure.

A method for constructing an integrated structure for optical applications in the context of solar technology, wafer technology, cooling channels, greenhouse illumination, window illumination, street lighting, traffic lighting, traffic reflectors or security films, the method comprising:

• obtaining a first carrier element;
• obtaining a second carrier element provided with at least one surface relief pattern comprising a number of surface relief forms and having at least one predetermined optical function relative to incident light, said second carrier element preferably comprising optically substantially transparent material enabling light transmission therethrough, and
• laminating, optionally in a roll-to-roll fashion, the first and second carrier elements together such that the at least one surface relief pattern is embedded within the established laminate structure and a number of cavities are formed at the interface of said first and second carrier elements.
