Представлен прототип твердотельной лампы на основе светодиодов InGaN с максимумами излучения 440, 460, 530 нм и AlInGaP с максимумами излучения 590, 630 и 660 нм, оснащенный источником стабилизированного тока и оптимизированным радиатором. Спектр излучения светодиодного осветителя представляет собой результат численного моделирования с применением экспериментально полученного спектра поглощения листа растения. Проведено сравнение эффекта применения светодиодов с воздействием натриевой трубчатой лампы. На основе оценки результатов биометрических измерений, которые проводили на протяжении всего эксперимента, показана возможность воздействия спектра предложенного светодиодного осветителя на рост растений.</p></abstract><trans-abstract xml:lang="en"><p>Solid−state lighting technology based on LEDs offers ample opportunities in plant lighting. This article presents a prototype of a solid−state lamp based on InGaN LEDs with radiation peaks of 440, 460, 530 and AlInGaP with radiation peaks at 590, 630 and 660 nm, equipped with a source of stabilized current and an optimized radiator. The emission spectrum of the LED illuminator is the result of numerical simulation using an experimentally obtained absorption spectrum of a leaf of a plant. The effect of using LEDs was compared to the effect of a sodium tubular lamp. Evaluation of the results of biometric measurements that were made throughout the experiment showed the possibility of the effect of the spectrum of the proposed LED illuminator on plant growth.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>светодиодный осветитель</kwd><kwd>твердотельный</kwd><kwd>спектр излучения</kwd><kwd>спектр поглощения</kwd><kwd>адаптивный светильник</kwd></kwd-group><kwd-group xml:lang="en"><kwd>light−emitting diode</kwd><kwd>solid−state lighting</kwd><kwd>illumination spectrum</kwd><kwd>absorption spectrum</kwd><kwd>adaptive lamp</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Massa G.
