LIGHT-EMITTING DIODE LAMP Russian patent published in 2024 - IPC F21S8/00 F21V29/83 

FIELD: lighting engineering.

SUBSTANCE: invention relates to the field of lighting engineering, namely to light-emitting diode lamps with a volumetric light-emitting diode module cooled by an external gas medium, the movement of which is organized by natural draft. LED lamp comprises a light-transmitting bulb with a volumetric LED module based on two, three or more LED filaments or LED lines, electrically connected to each other, with the power supply device located in the base, and with the lamp base, having heat-conducting bases, cooled coaxially installed in the bulb pipeline – conductive-convective heat exchanger with pipeline fittings of round, polygonal or star-shaped cross section, tightly connected on one side with a hole in the bulb wall, on the other side – with one end of the tubular base coaxially installed in the bulb, which other end is tightly connected to the bulb neck and the base, the base is perforated, so that the perforation holes in the base, the tubular base inner channel, pipeline and a hole in the bulb wall form a longitudinal channel passing coolant air.

EFFECT: creation of a light-emitting diode lamp in the standard size of an incandescent lamp with simultaneous provision of initial lighting characteristics of standard lighting fixtures – lamps, chandeliers, et cetera when installing LED lamps in them when replacing the incandescent lamp.
