LED LAMP WITH THERMOSYPHON COOLING AND LIGHTER ON ITS BASIS Russian patent published in 2018 - IPC F21S8/00 

FIELD: lighting.

SUBSTANCE: invention relates to high-power LED/LED/lamps and lighting fixtures based on them, having a high degree of environmental protection and local cooling of the lamp's LED module. The LED bulb contains a hollow volumetric LED module with a thermosyphon installed in thermal contact with the walls of the cavity with an extended tubular sheath with zones of evaporation and/or boiling, transportation, cooling and condensation of the heat transfer fluid vapour curved at an acute angle from 6 to 90° parts of said shell, surrounding the zone of cooling and condensation of the heat carrier vapour, with the radiator. At the same time, the LED module is provided with a supporting flange with mounting elements on the object on which a flat annular hinge is assembled, movably connecting the shell of the thermosyphon with this flange with the possibility of azimuthal rotation of its curved part with the cooling zone and condensation of the heat carrier vapour for gravitational orientation of the thermosiphon in space, providing transportation of condensate by gravity to the evaporation zone during operation of the lamp. The ring hinge of the lamp is made in the form of a union nut that surrounds the tubular shell of the thermosyphon and is screwed onto the annular flange of the flange of the LED module through an intermediate ring seal with locking and fixing the angular position of the thermosyphon in the lamp module; in space. The illuminator on the basis of this lamp provides for the implementation of the housing with sockets with openings outwards, paired with fixed support flanges of the LED modules, in the cavities of which there are thermosyphons with a curved shell on the outside and with a cooling coil for the condensation zone of the heat carrier vapour, space and fixing the position with the union nut of the hinge.

EFFECT: minimizes the size of the lamp and illuminator and improves performance due to the possibility of an arbitrary orientation of the thermosiphon, cooling the LED lamp module and the illuminator in space, when the lamp is operated in hermetically sealed and protected devices, and providing efficient heat removal to the surrounding area.
