Максимальная плотность мощности излучения матрицы составила ~18 Вт/см2 при непрерывном токе инжекции. Выполнена компьютерная модель, описывающая распределение температуры в матрице светодиодов в зависимости от потребляемой электрической мощности.

The maximum emission power density of the matrix was ~ 18 W/cm2 at continuous injection current. A computer model describing the temperature distribution in the matrix of LEDs depending on the supplied electrical power was developed. The simulation results are consistent with the results of measurement of the matrix LEDs temperature by a thermal imager, as well as with the results of determination of the LED active region temperature by the optical method.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>матрица светодиодов</kwd><kwd>температура активной области</kwd><kwd>распределение температуры</kwd><kwd>тепловая модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>LED matrix</kwd><kwd>active region temperature</kwd><kwd>temperature distribution</kwd><kwd>thermal model</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">http://www.digikey.com/en/articles/techzone/2015/aug/the-incredible-shrinking-led</mixed-citation><mixed-citation xml:lang="en">http://www.digikey.com/en/articles/techzone/2015/aug/the-incredible-shrinking-led</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Study of a QCW light-emitting-diode (LED)-pumped solid-state laser / K.
