FIELD: electricity.SUBSTANCE: invention relates to the lighting system, which includes light source designed to emit primary emission, emission-converting element designed to convert at least a part of primary emission to secondary emission, and filter designed to block emission generated in the system and having wave length shorter than the preset value of wave length cutoff. According to the invention the filter is intended to block a part of secondary emission due to placement of the wave length cutoff filter within emission spectrum of the emission-converting element.EFFECT: invention is oriented towards development of the lighting system that covers narrow emission spectrum within some area of electromagnetic spectrum, especially in red subspectrum.5 cl, 4 dwg, 1 tbl |
