Abstract: A LED driving arrangement has a main converter stage and a power commutation stage in parallel with an LED unit. An energy divert mode of operation is used during which a set current is provided to the LED unit, and the main converter stage is used to deliver a current larger than the set current.

This enables deeper dimming than the dimming level applied to the main converter stage, but without requiring an additional switch mode power converter.

Abstract: A LED lighting circuit has a plurality of LED segments connected in series. A switching arrangement is used to selectively bypass at least one LED segment to implement a tapped linear driver approach. Degrading of a component in the LED lighting circuit is detected, so that a first TLD current modulation scheme is implemented when no such degrading is detected whereas a second current modulation scheme, different from the first current modulation scheme, is implemented to compensate for said degrading. Said degrading is leading to an increase in a turning on voltage of one LED segment, and compared to said first current modulation scheme, said second current modulation scheme has a higher voltage threshold at which said LED segment is switched. In this way, protection may be provided for circuit components and the light output may be maintained at the desired level in the event of component degrading, such as LED chip failure or contact resistance changes.
