FIELD: electricity.
SUBSTANCE: invention relates to lighting engineering. A lighting instrument and a light-emitting element for acceleration of growth of plants. The instrument includes a single emission source in the form of a light-emitting diode that provides at least two emission peaks at the wave length interval of 300-800 nm, with that, at least one of the above emission peaks has width at half-height, which is equal to at least 50 nm. The above emission peaks of the light-emitting diode coincide with a spectrum of photosynthesis reactions of plants.
EFFECT: improving plant irradiation efficiency.
