LIGHTING SYSTEM Russian patent published in 2018 - IPC F21V7/00 F21V9/02 

FIELD: lighting.

SUBSTANCE: invention relates to the field of lighting technology and is intended to simulate natural sunlight. Lighting system (1), comprising light source (2) for providing light beam (3) of directional nondiffusive light with a first correlated color temperature along main direction (4) of the light beam, the direction of propagation of directional nondiffusive light is modified across light beam (3) and substantially parallel to main direction (4) of the light beam in the inner region and tilt to an increasing degree relative to main direction (4) of the light beam as the distance from the inner region increases, and lampshade-like structure (10) comprising lower block (12), which is illuminated from light source (2) on one side, and screen structure (14), provided on the opposite side, lower block (12) and screen structure (14) define light path (46). Lower block (12) comprises diffuse light generator (20) for generating diffuse light at a second correlated color temperature, which is greater than the first correlated color temperature, is at least partially transparent to the directional nondiffusive light of light beam (3), and is configured such that at least one divergent portion (53) of the light beam of light beam (3) enters the light passage (46), and screen structure (14) is spatially oriented with respect to main direction (54) of the light beam of divergent portion (53) of the light beam so as to be illuminated, at least part of divergent portion (53) of the light beam, thereby providing illuminated screen section (394, 395), acting as a source of scattered light. In addition, a lighting system with inclined diffusion light generators (20) and a system, uniting several lighting systems (20).

EFFECT: technical result is higher efficiency of illumination.
