Abstract: In an auto vibrancy mode, a vibrancy value for a lighting load may be automatically determined based on a selected color setting for the lighting load. The automatically determined vibrancy value may also be configured to emit light from the lighting load at or above a target CRI value for the selected color setting. The selected color setting may be a CCT value on the black-body curve or an x-y chromaticity value. If the selected color setting is CCT value on the black-body curve, the automatically determined vibrancy value may be a pre-defined vibrancy value that is configured to emit light from the lighting load at or above the target CRI value for the selected CCT value. If the selected color setting is an x-y chromaticity value, the automatically determined vibrancy value may be based on the distance between the selected x-y chromaticity value and the black-body curve.

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.
