Encapsulated white light-emitting device including photoluminescent layered structure |
| abstract |
The present invention provides a white light-emitting package (20) comprising: a solid-state excitation source (LED 30) for generating excitation light with a dominant wavelength in the range of 440nm to 470nm; and a layered photoluminescence structure. The layered photoluminescent structure comprises a first photoluminescent layer (32) comprising 75 wt% to 100 wt% of manganese-activated fluoride light based on the total photoluminescent material content of the first photoluminescent layer a photoluminescent material; and a second photoluminescent layer (34) comprising a photoluminescent material for generating light with a peak emission wavelength in the range of 500 nm to 650 nm. The second photoluminescent layer is disposed on the first photoluminescent layer and the first photoluminescent layer is adjacent to the solid state excitation source than the second photoluminescent layer. |
