Angular color distribution uniformity has been one of the most relevant properties in the development of white light-emitting diodes (WLEDs), since color consistency and uniformity are crucial factors in quality evaluation of a WLED. Here, particularly considering the need to overcome the poor chromaticity usually associated with WLED, we introduce a new design for the remote-phosphor package, namely...
In this paper, we propose a method to enhance luminous efficacy and color quality of the multi-chip white LED lamps (MCW-LEDs) at high color correlated temperature. This can be done by the incorporation (La, Ce, Tb)PO4:Ce:Tb green phosphor (LaTb) with YAG:Ce yellow phosphor compounding. Index, the employment this green phosphor into MCW-LEDs could bring a great effect on the optical performance of...
