      • Phosphor-Converted Light-Emitting Diodes of Preferential Color Properties

        Current development and optimization of LEDs spectral power distributions (SPDs) usually are focused on achieving the highest color fidelity in terms of CIE color rendering index CRI as well as the luminous efficacy for energy-saving reasons. Therefore we report on an alternative approach and innovative color rendering paradigm, where light sources, of preference color rendering SPD are presented to be competitive and even surpassing the high fidelity light sources in terms of subjective ranking. The designed prototype PrefLED lamp of 2900 K correlated color temperature (CCT), with moderate color saturation ability was developed and psychophysically validated by a side-by-side comparison with a halogen lamp (CCT = 2912K) under quasi-identical experimental conditions. PrefLED was found to be perceived as more bright, vivid and attractive, therefore preferred for offices, grocery stores, shopping malls and restaurants as well as kitchen or bathroom. However, the halogen lamp was claimed to be more peaceful and natural and preferred for illumination of sleeping room.
