Abstract
A light bulb apparatus includes a bulb shell, an antenna, a driver, a light source plate and a bulb cap. The light source plate has a first layer and a second layer. The LED module is disposed on the first layer. The second layer includes a metal portion. The metal portion carries heat generated by the LED module for heat dissipation. The antenna is disposed upon the first layer. A bulb cap is connected to an external power. The driver is electrically connected to the antenna for receiving a wireless signal. The driver converts the external power to a driving current supplied to the LED module.
