Abstract:

The article discusses one of the ways to obtain a contrasting boundary between the illuminated and unlit areas of the object (illumination technology Flat Beam) in LED lighting systems using secondary optics in the form of a flat mirror surface. The results of studies of high-power LED light sources with different emitting surface areas and with three proposed options for fixing a flat mirror surface are presented. It is shown experimentally that the optical system for LED light sources in the form of a flat mirror surface allows changing the luminous intensity curve of LED light sources, converting it in a given plane from a cosine to a concentrated one. This is how the Flat Beam lighting technology is realized. Variants of the practical application of this lighting technology obtained by using a flat mirror surface with LEDs are also proposed.
