The design specifics of the diffused lighting system of premises based on LEDs

Abstract

In the article the design specifics of the diffused lighting system of premises based on LEDs is being considered, which is determined by such problems of the designing LEDs lighting systems: formation of multiple shadows using groups of open LEDs in luminaires direct light; the need for vision protection of the users from the direct light of LEDs as the high light efficiency and miniature sizes of modern LEDs lead to the significant luminous flux in one point.In the process of work it was defined that the promising solution to the problems outlined above is using the diffused lighting, which is considered to be one of the most comfortable in terms of avoidance of disability glare and discomfort glare. However, the diffused lighting has such a disadvantage as monotony. As a result, the study suggests ways to avoid the monotony of the light environment which is formed by the diffused lighting: the main one is the enrichment of the shape of the luminaires and lighting systems through the use of complex and structured light diffusing surfaces to form them; the additional one is the enriching the colour of the light due to the nuanced differences in colour temperature of separate luminaires among the variety of those, which are in the general lighting system.The theoretical position outlined above are practically applied in: the series designed shades (PU 112427, PU 130594), which construction is based on regular (hexahedron or cube, octahedron, icosahedron) and semi-regular (cuboctahedron, rhombicuboctahedron) polyhedrons; the series LED luminaires for lighting of shades (PU 128832) and for forming the systems of diffused lighting (PU 121313). Also, it was found, that contemporary design of the luminaires with diffused light have frequent use OLED on a rigid or flexible lining as light sources.
