The Optoelectronic Semiconductor Device Based of the Leds to Improve Plant Growth

Abstract

Significant interest in light emitting diodes (LEDs) is due to the great potential for their application to create a variety of electronic and optoelectronic devices that characterized by low power consumption and the required spectral range of radiation. LEDs are an energy-efficient approach to greenhouse lighting that has technical advantages over traditional light sources. In this regard, a universal multi-wave phytolamp was created with the ability to change the spectral composition of radiation to increase plant growth efficiency at various stages of development. Experimental results showed that additional irradiation of rye seeds with blue InGaN and red AlGaAs LEDs at the germination stage positively affects the development of rye sprouts and allows one to increase all characteristics of the grown material by an average of 1.5 times.
