Abstract

This study presents the light-spectrum modification of warm white-light-emitting diodes ( w -WLEDs) with 3D colloidal photonic crystals (3D CPhCs) to approximate candlelight. The study measures the angular-resolved transmission properties of the w -WLEDs with CPhCs, which exhibit photonic stop bands based on the CPhC photonic band structures. The w -WLEDs with 3D CPhCs produce a low correlated color temperature of 1963 K, a high color-rendering index of 85, and a luminous flux of 22.8 lm (four times that of a candle). This study presents the successful development of a novel low-cost technique to produce candlelight w -WLEDs for use as an indoor light source.
