GREENHOUSE IRRADIATOR Russian patent published in 2024 - IPC A01G9/14 

FIELD: lighting.

SUBSTANCE: invention relates to control over operating modes of lighting equipment in industrial greenhouses with mixed (hybrid) type of light sources. Irradiation installation for greenhouses includes light sensors 1, connected to a device for controlling and collecting data on illumination indicators, connected to actuators 3, connected to irradiation elements 4 and 5. Control device 2 is made with possibility of collection, processing and fixation of illumination indicators, taken by light sensors 1 on current state of illumination, comparison of obtained values with optimal illumination values corresponding to natural illumination cycles, reflecting phases of dawn, day and dusk, determining the necessary corrections based on the obtained data and transmitting them to actuating devices 3 associated with irradiating elements 4 and 5. Latter are made in the form of a set of unregulated high-pressure sodium lamps 5 (HPSL) and adjustable light-emitting diodes 4 (LED) in such a way that the light flux from them in total corresponds to the illumination optimum for growing plants in each of the phases of dawn, day and dusk. Light flux of LED 4 is greater than or equal to power of HPSL 5, and the number of each of the irradiation elements HPSL 5 and LED 4 is at least one. Emitted light flux of the irradiating element with HPSL lamp 5 does not exceed 50% of the maximum established for the given type of plants. Irradiation elements HPSL 5 and LED 4 are connected in parallel.

EFFECT: invention will make it possible to provide illumination of plants with the help of artificial light sources, corresponding to natural cycles of illumination, including modes of dawn, daytime and dusk, at a specified time of the year with optimization of lighting costs.
