Abstract. Discussed in the article is the possibility to create a wall-mounted LED luminaire with a built-in cooling system for a volumetric LED module put in the enclosed volume of the diffuser. The use of aluminum heat pipe with a threaded capillary structure has been proposed for cooling high-power LEDs of the volumetric module in the luminaire design. It has been shown that the use of heat pipe with a simple capillary structure allows the heat flux from the LED module to be efficiently transferred outside the light diffusing area to the decorative radiator located on the top of the lamp and to disperse it into the surrounding air. The proposed design of the wall lamp with heat pipe allows to increase the luminous flux and durability of the luminaire.

Keywords: LED, wall lamp, cooling of LED modules, heat pipe.
