Abstract

The paper investigates the possibility of creating a device that allows you to adjust the radiation spectrum. The validity of this work lies in the fact that the creation of a phyto-emitter with a variable irradiation spectrum allows you to set the necessary spectra required by certain crops and depending on the stage of vegetation of the plant, without any additional installation and the use of several phyto-emitters, and also allows you to save electricity due to the effects of certain spectra required by certain crops. During the experiment, a power source for a phyto-emitter based on the LM-317 chip and a resistor ballast was developed. A multi-crystal LED with crystals of different spectrum was chosen as a light source. In this paper, the spectral distribution and chromaticity coordinates of LED crystals were investigated at different values of the current strength. Spectral intensity of the wavelength range and chromaticity coordinates were studied as spectral characteristics. The measurements were carried out for each LED crystal, at different current values; for all LED crystals turned on at the same time, at different current values.
