In this paper, radial LSFs for direct-lit BLUs are modelled with three parameters and can render different shapes for a same influence. Diverse LSF shapes are analyzed in terms of robustness in production as well as power saving capabilities regarding local-dimming. Characteristic measures for an optimum shape are proposed.
