WIRELESS LED TUBULAR LAMP DEVICE Russian patent published in 2019 - IPC F21K99/00 F21V23/00 F21Y101/00 F21Y103/00 

FIELD: lighting engineering.

SUBSTANCE: wireless LED tubular lamp device (100) comprises at least partially transparent tube (7), at least one light-emitting diode (1) arranged inside said tube, at least one LED driver (4), controller (5) of LED (1), radio-frequency antenna (30, 40), connected to controller, for reception and sending of wireless commands. Radio-frequency antenna is a bent antenna having antenna elements (31, 32, 33; 41, 42, 43) located in common curved plane, wherein said antenna comprises a grid of a semi-loop wire antenna, and the grid of the semi-loop wire antenna comprises a plurality of coils of the line, wherein a plurality of coils of the line is spirally continuous along the axial direction as a whole, wherein the axial direction is parallel to the axis of tube (7), and each rotation of the coils of the line extends along the entire perimeter of tube (7).

EFFECT: technical result is higher radiation efficiency.
