FIELD: lighting.
SUBSTANCE: invention relates to lighting equipment, in particular, to lighting units with a cooling apparatus using high-power LEDs. Proposed is a LED light fixture with liquid cooling, comprising a body 1 made of a heat-conducting material filled with a heat removal liquid, a hermetically sealable cover 7 with a hole 8 for pouring a liquid, and a printed circuit board 2 with orientation in the longitudinal direction. The body 1 is made according to the blowing technology, wherein a part of the longitudinal surface thereof is made wave-like in the cross-section 6, the printed circuit board 2 with electronic components located inside the transparent body has through heat removal holes 4.
EFFECT: increased efficiency of heat removal from LEDs due to the increased heat dissipation surface area of the light fixture; simplification of the design of the LED light fixture.
