LAMINATE STRUCTURE WITH INNER CAVITIES AND METHOD OF ITS MANUFACTURING Russian patent published in 2016 - IPC B32B33/00 H01L31/48 H01L31/52 G02B5/00 

FIELD: construction.

SUBSTANCE: structure comprises the first bearing component, such a part from plastic or glass, comprising an optically transparent material, which may transmit radiation, and the second bearing component equipped with at least one surface relief pattern, which comprises multiple elements of surface relief, and made as capable of realisation of at least one specified optical function in respect to falling radiation. The second bearing material comprises optionally an optically transparent material capable of radiation transmission. At the same time the first and second bearing components are connected by lamination so that inside the produced laminate structure there is at least one surface relief pattern, and between the first and second bearing components there are functional cavities connected optically with the specified pattern. The optical function is provided and configured by dimensions, material, position and/or matching of internal elements of the relief.

EFFECT: development of a laminate structure making it possible to increase efficiency of radiation supply.
