    Abstract: An AC LED module with an improved power factor for coupling with an AC source includes a plurality of LED strings and a plurality of connecting-to-middle drive elements. The LED strings are coupled in parallel between two ends of the AC source, and each of the LED strings further includes a respective number of LEDs connected in series. The connecting-to-middle drive element assigned to a respective LED string has two connection point, one connected to one end of the AC source while another being connected with a middle point between two consecutive LEDs in the same LED string.

    Abstract: An AC LED module includes a substrate, a bridge rectifier unit a constant current unit and an LED chip set. The bridge rectifier unit mounted on the substrate further includes an output and an input coupled with an AC source. The constant current unit, mounted on the substrate and coupled with the output of the bridge rectifier unit, further includes at least one current regulative diode. The LED chip set mounted also on the substrate is electrically coupled with the constant current unit.
