LIGHTING DEVICE Russian patent published in 2017 - IPC F21S8/00 

FIELD: lighting.

SUBSTANCE: lighting device comprises one or more LEDs or one or more LED matrices for generating a light flux emitting in the ultraviolet or blue regions of the optical spectrum, and of two or more secondary remote lenses or multilenses for controlling the light flux, cascaded or cascaded and parallel to the direction of the optical axis of the emission of LED or several LEDs or of one or more LED matrices. In this lighting device luminophor particles or mixtures, converting the emission of the LEDs or LED matrices into the emission of missing parts of the spectrum of the visible range or required wavelengths, are introduced onto the surface of the optically transparent binder or its part or directly into the volume of the multilenses or its part.

EFFECT: extended scope of application of the lighting device by increasing light output, decreasing glare effect, luminophor consumption, increasing reliability and manufacturability.
