FIELD: lighting engineering.SUBSTANCE: invention relates to lighting devices, providing lighting with light, the most appropriate spectrum of sunlight at the expense of use of light-emitting diodes. Luminary contains a set of LEDs with different emission spectra simulating the photosynthetically active part of the solar spectrum equipped with power drivers. Use LEDs whose maximum radiation amplitudes are in the wavelength range 430–650 nm. Spectra of used LEDs overlap each other in different spectral regions of the range, preferably at a level of 0.4–0.6 of the maximum amplitude at the central wavelength of the radiation. Six types of LEDs of different spectrum are used: Warm White, Royal Blue, Blue, Sky Blue, Green and Growing Light, with a possible deviation from the central wavelength at ±15 nm. Drivers of said LEDs are configured to supply power of such a value that the level of the light flux from the corresponding LEDs is equal 0.94; 0.22; 0.57; 0.81; 0.89 from the level of the light flux emitted b
