LAYER PACKET CONTAINING LUMINESCENT MATERIAL, LAMP, ILLUMINATOR AND METHOD OF MANUFACTURE OF LAYER PACKAGE Russian patent published in 2017 - IPC H05B33/14 H05B33/08 H05B33/04 B82Y30/00 F21V9/16 H01L33/58 

FIELD: lighting.

SUBSTANCE: layer stack (100) comprises a first outer layer (102), a second outer layer (106), and a fluorescent layer (104). The first outer layer (102) and the second outer layer (106) are a polymeric material transmitting light, with an oxygen transmission rate below 30 cm³/(m²⋅day), measured at standard temperature and pressure (STP). The luminescent layer (104) is disposed between the first outer layer (102) and the second outer layer (106) and comprises a matrix light transmitting polymer and a luminescent material (108) adapted to absorb light in accordance with the absorption and conversion spectrum of a portion of the absorbed light into the light spectrum of light radiation.

EFFECT: increase the longevity of the light source with organic luminescent materials.
