Abstract
A light emitting diode (LED) filament light bulb is disclosed. The LED filament light bulb includes a plurality of LED filaments, an RF driver, an antenna, and a cover. The antenna defines a first end portion and a second end portion, where the first end portion of the antenna is electrically connected and in signal communication with the RF driver. The cover defines an external wall and a support structure. The external wall defines an interior volume and the support structure defines an evacuation passageway and a cavity. The evacuation passageway and the antenna are both received within the cavity of the support structure and the evacuation passageway is fluidly connected to the interior volume of the cover.
