LIGHTING DEVICE WITH THE FIRST AND SECOND RELATED AND MUTUALLY MOVABLE ANTENNAS Russian patent published in 2018 - IPC H01Q1/22 F21V23/04 

FIELD: lighting equipment.

SUBSTANCE: invention relates to the field of lighting devices, and more particularly to a lighting device with a first and second antenna suitable for transmitting of radio frequency (RF) signals. Result is achieved by the fact that the lighting device (100) with the light source and the heat dissipating element comprises: a radio frequency communication circuit (102); first antenna (105) electrically connected to the radio frequency communication circuit and supported by the lighting device first portion (115); and a second antenna (125) configured to communicate with external devices and electromagnetically coupled to the first antenna, thereby the second antenna is adapted to be excited by the first antenna and to excite the first antenna, wherein the second antenna is configured to establish communication with external devices and is supported by the lighting device second portion, wherein the lighting device second portion is movable relative to the lighting device first portion.

EFFECT: technical result is an increase in the reliability of the radio-frequency signals transmission in a wide beam.
