title = "Color rendering ability and luminous efficacy enhancements in white light-emitting diodes",
abstract = "There exists a fundamental trade-off relation between color rendering index (CRI) and luminous efficacy; in other words, improvements in one are generally detrimental to the other. We analyze and demonstrate through simulation that phosphor-converted white LEDs with dual-blue emitting active regions, as opposed to single-blue emitting active regions, significantly enhance color rendering ability while maximizing the output luminous flux. The improvements are achieved over a broad range of correlated color temperatures.",
