Using triple-layer remote phosphor structures LaVO4:Eu3+ and ZnS:Cu,Sn to improve the chromatic uniformity and luminous quality of WLEDs
This research paper investigates the novel triple remote phosphor layer for improving the remote phosphor’s angular chroma uniformity (ACU) of down-light lamps by using remote micro-patterned phosphor layers (RMPP). In addition, introducing the…

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…

The options in remote phosphor structure for better white LEDs color quality
The WLEDs configuration with remote phosphor layers has higher
luminescent performance than WLEDs with dispense coating or conformal coating and is applied for many modern devices. However, managing the chromatic performance of lighting structure…

Multilayer phosphor-in-glass packaging for the development in WLED color uniformity
When mentioning the remote phosphor structure, the most noticeable
advantage is its higher luminous flux than any other structure’s. However,
there are existing flaws in their color uniformity and color rendering index
(CRI). Thus, the…

The application of (Y,Gd)BO3:Tb3+ and CaGa2S4:Mn2+ phosphors to remote white light-emitting diodes
The remote phosphor structure is superior to the conformal phosphor and the in-cup phosphor in terms of lighting efficiency; however, managing the color quality of the remote phosphor structure has been a nuisance to the manufacturers. To address…
