LED LIGHTING DEVICE AND SYSTEM, AND ANTENNA ARRANGEMENT METHOD

摘要

A light emitting diode (LED) lighting device comprises a LED light source assembly installed on the top of a heat sink body, a LED driving and power supply unit configured to drive the LED light source assembly and provide electrical power for the LED lighting device, a heat sink (20) including the heat sink body (24) and a heat sink covering (22), and a radio frequency (RF) antenna (30) installed on periphery of the heat sink body. The heat sink covering (22) has an opening (23). A plane including the highest point of the top of the heat sink body (24) is higher than a plane including the opening of the heat sink covering (22) and a plane including the highest point of the RF antenna (30) is at the same level or lower than the plane including the highest point of the top of the heat sink body (24).
