对于由蓝色氮化铟镓芯片、黄色铝酸盐荧光粉和红色磷化铝镓铟芯片组成的类似烛光的三峰白色发光二极管（LED），其显色指数（CRI）和发光效率（LE）之间的权衡已被研究。
The tradeoff between the color rendering index (CRI) and the luminous efficacy (LE) for candle-like three-hump white light-emitting diodes (LEDs), which consist of blue InGaN chip, yellow aluminate phosphors, and red AlGaInP chip, has been investigated. Spectral models have been separately developed for the optimization process after experimentally measuring spectral power distributions of phosphor materials and semiconductor chips. By filtering billions of defective spectral data with a nonlinear program, optimal values of LE of 272 lm/W and CRI of 96 (CRI No.9 of 98) at a correlated color temperature of 2000 K can be achieved, while LE and CRI are 0.1 lm/W and 83 for candles. These three-humps LEDs are capable of achieving excellent photometric and chromatic performances of candle-like white light. Finally, this study can serve as a critical guide for manufacturing high-CRI candle-like white LEDs.
