Increased luminaire gamut as well as increase in luminous efficiency is found when the LED based luminaire is driven
by a hybrid PWM/AM dimming technique. This technique is applicable to any n-chromaticity luminaire but it is especially
suitable for trichromatic RGB luminaires that do not have inherent degrees of freedom. Diodes' properties under
the hybrid dimming method were measured and used in nonlinear optimization routine to find the driving conditions that
yield e.g. the highest possible efficacy for a given color point.
