MULTISPECTRAL PHYTORADIATOR Russian patent published in 2024 - IPC A01G9/20 A01G9/26 A01G7/04 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, in particular to closed type plant growing. Multispectral phyto-irradiator comprises 1₁-1_M light-emitting diodes, 2₁-2_M light-emitting diode radiation intensity control drivers implemented on the basis of controlled current sources, 3₁-3_M current meters, 4 port controllers, a central controller and a memory unit. First outputs 4 of the port controllers are connected to the corresponding inputs of the central controller, the input of which is connected to the output of the memory unit, the input of which is connected to the output of the central controller, first outputs of which are connected to inputs of corresponding LEDs radiation intensity control drivers, outputs of which are connected to inputs of corresponding current meters, first outputs of which are connected to inputs of corresponding groups of light-emitting diodes, second outputs of current meters are connected to inputs of central controller. First outputs of all 4 port controllers and first 4 inputs of the central controller are bidirectional. Second input of each of 4 port controllers is bidirectional and is 4th input-output of the device, which includes 7₁-7_M temperature sensors, a switch, an analogue-to-digital converter, a clock generator and a binary counter. Outputs 7₁-7_M of temperature sensors are connected to information inputs of the switch, the output of which is connected to the input of the analogue-to-digital converter, the output of which is connected to the input of the central controller, the control output of which is connected to the control input of the switch. Output of the binary counter is connected to the input of the central controller. Output of the clock generator is connected to clock inputs of the central controller, a memory unit, a binary counter, an analogue-to-digital converter and all 4 port controllers, wherein M>N, where N is monochrome radiation.

EFFECT: device provides expansion of functional capabilities due to realization of reproduction of dynamic radiation and increase of reliability due to measurement of temperature of selected groups of light-emitting diodes.
