FIELD: lighting equipment.
SUBSTANCE: invention relates to the field of lighting technology and can be used for LED light fixture (10) in a livestock room. LED light comprises base plate (13) provided with at least one first LED device (21–25) configured to emit light during operation, which simulates the daylight conditions. First LED device comprises a plurality of first type LEDs (28) that have at least one peak wavelength in the wavelength range between 500 nm and 600 nm, and at least one second type LED (27), which is a blue LED with a peak wavelength in the wavelength range between 440 and 480 nm. Luminaire is provided with optical system (30) made in the form of a lens in such a way that the intensity of the light emitted by the LEDs is distributed according to distribution (40), which has a peak intensity at an angle of more than zero degrees from the optical axis of the luminaire, said intensity distribution (40) having a generally bat wing shape.
EFFECT: increase of radiation efficiency.
