LED LAMP WITH COOLING BY HEAT PIPE AND ILLUMINATOR ON ITS BASIS Russian patent published in 2017 - IPC F21S8/00 

FIELD: lighting.

SUBSTANCE: lamp comprises a volumetric LED module in the form of a right prism or two conjugate bases of truncated pyramids with LEDs of 0.5-3 W power assembled at the edges, made or installed in thermal contact on the jacket of the evaporation zone of a heat pipe (HP) with a wick having a capillary structure, and a biphase heat-transfer fluid partially filling the pipe. The evaporation zone of the HP is connected through the adiabatic zone to the vapour condensation zone of this heat carrier, cooled by a removable finned annular radiator cooling system mounted on the thread and/or by sliding fit. The specified area of the HP jacket with a removable radiator cooling system, when installing the lamp in the illuminator, is taken from its housing into the surrounding space for cooling. The elements of the current lead and lamp mounting in the illuminator are assembled on a supporting flange made on the jacket at the point where the FP adiabatic zone adjoins the vapour condensation zone, with connection to the LED module and to the converter of the power network discharged from the lamp into the illuminator compartment or installed on the jacket of the adiabatic zone inside the lamp. The supporting flange is made with holes for the bayonet mechanical fastening of the lamp on a flat wall with a hole of the illuminator socket in thermal contact with it by pressing it with a removable HP radiator. In an illuminator based on a LED lamp with HP cooling, containing a protected or unventilated housing with one or two sockets for mounting the lamp with the LED module protected by an optically transparent bulb, each lamp is mounted in a socket with a flat wall perpendicular to the main optical axis of the reflector and with an axial hole for placing the jacket of the vapour condensation zone of the HP heat carrier, taken out of the protected or unventilated housing into the surrounding space with sealing and thermal contact of the mentioned housing wall between the supporting flange and its removable annular jacket radiator cooling system, providing high cooling efficiency.

EFFECT: improving performance by improving the efficiency of lamp cooling when working in illuminators with a high degree of environmental protection and in unventilated devices.
