    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 (VLow) which is also derived from the rectified AC mains voltage (4), wherein the low supply voltage (VLow) is generated from unutilized voltage of the LED-string (2′).

    Abstract: An LED module, having a carrier, a first group and a second group of LED chips arranged on the carrier, optionally one or more further groups of LED chips, and a layer covering all LED chips and containing at least one color conversion material, which converts the spectrum of the LEDs of one or all groups into a spectrum with a different dominant wavelength. Every group comprises at least one LED chip, preferably a plurality of LED chips. The LED chips of one group are preferably connected in series and can be supplied starting from the same electrical supply. The LED chips of different groups can be supplied independently of one another, starting from different electrical supplies.
