AC LED lamp

The invention discloses an AC LED lamp, including AC input end and connected to the AC input AC LED filament between end, the AC LED filament comprises a light-emitting diode array in parallel at least two groups of conduction in the opposite direction. The AC LED filament can also have an integrated structure.

The invention has the advantages that the filament in the AC LED AC input between direct access to at least two columns of conduction in the opposite direction, save the existing circuit in AC / DC rectifier, voltage regulator, filter driver circuit without switch power supply more expensive, only need to work in tandem (by the filament voltage all of the LED tube core number and the working voltage of V < sub > F < / sub > to determine, can carry out standardized design, suitable for different applications) to adapt the AC LED lamp is directly connected to the AC power supply can be economical and efficient LED lighting.
