Abstract
A lighting apparatus includes multiple LED modules, a driver and a wireless circuit. The driver for converting an external power to a driving current. The light source plate includes a first metal layer, an insulation layer and a second metal layer. The second metal layer has a larger thickness than the first metal layer. The first metal layer has a first portion and a second portion. The first portion is used for electrically connecting the multiple LED modules. The second portion forms an antenna radiation part. The insulation layer is between the first metal layer and the second metal layer. The wireless circuit electrically connected to the second portion of the first metal layer. The antenna radiation part is used as an antenna for receiving a wireless signal.
