A lighting apparatus includes a LED module, a light source plate, a heat sink, an antenna, a driver and a light housing. The light source plate is used for holding the LED module. The heat sink has a bottom plate and a lateral wall. The light source plate is placed on the bottom plate. The antenna is disposed on the lateral wall. The driver is used for generating a driving current to the LED module. The driver has a wireless circuit. The wireless circuit is electrically connected to the antenna for transmitting a wireless signal. The light housing is used for holding the heat sink so that the LED module emits light toward a light opening of the light housing.
