A light emitting diode (LED) lighting device is provided. The device includes an LED light source assembly installed on the top of a heat sink body, and an LED driving and power supply unit configured to drive the LED light source assembly and provide electrical power for the LED lighting device. The device also includes a heat sink including the heat sink body and a heat sink covering, where the heat sink covering has an opening; and a plane including the highest point of the top of the heat sink body is higher than a plane including the opening of the heat sink covering. Further, the device includes a radio frequency (RF) antenna installed on periphery of the heat sink body. A plane that includes the highest point of the RF antenna is at the same level or lower than the plane that includes the highest point of the top of the heat sink body.

LED lighting device and system, and antenna arrangement method

Antenna-containing LED lighting devices, systems and configuring methods are provided. An exemplary LED lighting device includes an LED light source component unit and an LED driving circuit and power supply unit configured to drive the LED light source component unit and to power the LED lighting device. The LED lighting device further includes a heat sink, an RF antenna, and an RF circuit. The RF antenna is configured to have an antenna top plane containing a highest point of the RF antenna coplanar with or lower than a heat sink top plane containing a highest point of the heat sink. The RF antenna is configured without affecting a light-emitting path from the LED light source component unit.
