FIELD: lighting engineering.
SUBSTANCE: invention relates to the field of lighting engineering, in particular to LED lighting devices and can be used for irradiation of vegetable and green crops. A liquid phyto-emitter for plants contains LED filaments connected to a power source, placed on a profile and fixed inside a sealed transparent housing filled with a transparent heat-conducting dielectric liquid. A protective temperature sensor connected to the power supply unit on which the potentiometer is placed is installed in the central profile. The housing is closed on both sides with sealed flat end caps and sealing rubber rings with a hole for the central profile, the lighting elements are made in the form of LED filaments fixed to the profile with a gap. The volume of the dielectric heat-conducting liquid is 5-10% less than the volume of the bulb.
EFFECT: increase in the service life of LED elements, energy efficiency and reliability of the phyto-emitter.
