DEVICE PROVIDING POSITIVE EFFECT IN GROWING PLANTS IN SPECIALLY PROTECTED ENVIRONMENT

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to means of illumination for plants in growing in protected environment. The device comprises: a computer (1) with interface (2), a control unit (3), a unit (4) of power supply, at least one lamp (7), a fan (5) for cooling LED elements and supply of CO₂ or nitrogen (N) from the reservoir (6) connected through the corresponding line (8). And the lamp (7) consists of a rack (17) with the tubular connection (29) and the support (15) with a plafond (14) attached to it, in the centre of the upper surface (21) of which there is an opening (22). On the side surfaces the LED elements (13) are symmetrically located, with LEDs (12) and heat exchangers, the LED driver (27), the ventilation openings (19) and the connecting panel (25). And the control device (3) consists of: a module (9) to create the basic sequence of rectangular pulses with the predetermined frequency and regulation of their duration, that is the ratio of signal/pause; the module (10) to determine the number of pulses corresponding to the individual colours and their position in time intervals Tfs and Tfp for photosynthetic and phyto-prophylactic spectra, as well as the base frequency of radiation fo; and a module (11) for manual selection of mode and data entry.;EFFECT: invention provides an improvement in growth and yield of plants by providing additional lighting with its regulation in greenhouses.;7 cl, 16 dwg
