DEVICE FOR IRRADIATING PLANTS IN HOTHOUSE WITH MULTITIER NARROW-RACK HYDROPONIC INSTALLATION Russian patent published in 1994 - IPC

FIELD: agricultural engineering. SUBSTANCE: device comprises radiation source and reflector. Device has a drive for reversible motion of radiation source 9 around plant 6. Reflector has the form of horizontal pipe 1 secured on rack 3 and has circular guides 7,8 on its ends, said guides corresponding to trajectories of movement of radiation source 9. The latter is constituted by luminescent lamp. The holder at one end of lamp is connected to the drive 10 while that at the other end of the circular guide 8 is disposed on the opposite end of reflector. This device reduces power expenditure and light losses and improves productivity of plants in hothouse. EFFECT: improved design. 4 cl, 3 dwg
