ILLUMINATED PANEL FOR ESCALATOR, MOVING SIDEWALK OR LIFT Russian patent published in 2018 - IPC F21V8/00 

FIELD: lighting.

SUBSTANCE: panel (20) illuminated by at least one lighting device has a structure comprising a plurality of layers (61, 62, 63, 64, 65). The side surfaces (61A, 61B, 62A, 62B, 63A, 63B, 64A, 64B, 65A, 65B) of each layer (61, 62, 63, 64, 65) are limited in their planar extension by the section (61C, 62C, 63C, 64C, 65C) of the edge. The layers (61, 62, 63, 64, 65) of the structure are adjacent to each other by their side surfaces (61A, 62A, 62B, 63A, 63B, 64A, 64B, 65B). The first layer (61) is a reflective coating (61), the second layer (62) is a transparent plate (62) made of polymer material, with the possibility of illumination along the edges containing light-scattering particles, the third layer (63) is the first glass plate (63), the fourth layer (64) is a transparent polymer layer (64), and the fifth layer (65) is the second glass plate (65).

EFFECT: increased uniformity of lighting.
