LED LAMP Russian patent published in 2020 - IPC F21V23/00 F21V19/00 F21Y101/00 

FIELD: lighting engineering.

SUBSTANCE: invention relates to lighting engineering and specifically to LED lamps having a printed-circuit board and a threaded base (Edison base) for connection to a power supply network. LED lamp comprises a hollow radiator housing; optically transparent diffuser fixed on radiator housing; light-emitting diodes mounted on printed-circuit board installed on end of radiator housing with possibility of heat exchange; an elongated dielectric circuit mounted longitudinally to the axis of the lamp; power supply; threaded base made in the form of a hollow thin-walled cylinder, at the bottom of which a contact element is fixed, is characterized by that the first remote part of the elongated board has two ledges made with possibility of mechanical connection to the LED board; second remote part of the elongated board is placed in the socket cavity, is equipped with perforation made with possibility of threaded connection with the base. Projections on the first remote part of the elongated board can be metallized for electromechanical connection with contact tracks of the LED board.

EFFECT: simplification of the lamp design due to reduction of the number of structural and fastening elements.
