FIELD: lighting. SUBSTANCE: LED lighting device contains a printed circuit board (PCB) of a planar structure, an LED chip mounted on the PCB surface, a support connected to another PCB surface, and a radiator connected to the support and intended to dissipate the heat emitted by the LED chip. The support is made with a non-continuous through hole, passing through both surfaces of the support, and is connected to the radiator. The radiator comprises a heat pipe circuit formed as capillary tubes in which the working fluid is disposed and has a heat conducting portion to transfer heat from the support and a heat dissipating portion to dissipate heat. At that, the radiator heat pipe circuit is connected to the support when the radiator heat absorbing portion, inserted from the support surface into the said non-continuous through hole, comes into contact with the PCB. EFFECT: simplified design and increased efficiency of heat sinking. 4 cl, 5 dwg

Изобретение относится к области светотехники. Техническим результатом является упрощение конструкции и повышение эффективности теплоотвода. Светодиодный осветительный прибор содержит печатную плату (ПП) планарной структуры, светодиодный чип, установленный на поверхности ПП, опору, связанную с другой поверхностью ПП, и радиатор, связанный с опорой и предназначенный для рассеивания тепла, выделяемого светодиодным чипом. Опора выполнена с несплошным сквозным отверстием, проходящим через обе поверхности опоры, и связана с радиатором. Радиатор содержит контур тепловой трубки, сформированной в виде капиллярных трубок, в которых расположена рабочая текучая среда, и имеет теплопроводящий участок, предназначенный для передачи тепла от опоры, и теплорассеивающий участок для рассеяния тепла. При этом контур тепловой трубки радиатора связан с опорой, когда теплопоглощающий участок радиатора, вставленный от поверхности опоры в указанное несплошное сквозное отверстие, входит в контакт с ПП. 3 з.п. ф-лы, 5 ил.
