Chroma consistency and luminous efficacy for a WLED using remote phosphor configuration with a tri-layer design
The light quality of white-light-emitting diodes (WLEDs), an essential
element for the improvement of WLEDs performance, can now be estimated by the angular color uniformity (ACU). In this study, a single
micro-patterned layer is used to compare…
