Abstract:
The invention relates to a direct AC driving circuit and a luminaire for driving at least one LED, the driving circuit comprises a LED string ( 2 ) that comprises a series connection of at least two LEDs, wherein the LED string ( 2 ) is directly powered from a rectified AC mains voltage and a LED string switching unit ( 1 ) that is configured to control at least one LED shortening unit ( 1 ′) that is arranged in parallel to at least one LED of the LED string ( 2 ′). According to the invention, the driving circuit comprises means configured to provide a low supply voltage (V Low ) which is also derived from the rectified AC mains voltage ( 4 ), wherein the low supply voltage (V Low ) is generated from unutilized voltage of the LED-string ( 2 ′).

Claim (Index 6):
The driving circuit according to  claim 5 , wherein the further regulation means is a further LED or a Zener diode.
