摘要： A method of applying at least two phosphors to an LED, wherein a first phosphor material having a lower absorption, shorter luminescence decay time, and/or lower thermal quenching than a second phosphor material is positioned closer to the LED than the second phosphor. Such an arrangement provides a light emitting device with improved lumen output and color stability over a range of drive currents.

摘要： Halophosphate luminescent materials co-activated with europium and manganese ions and having the general formula of (Ca,Sr,Ba,Mg)5(PO4)3:Eu2+,Mn2+ are disclosed. The inclusion of manganese shifts the peak emission to longer wavelengths and, thus, is beneficial in generating a bright yellow-to-orange light. White-light sources are produced by disposing a halophosphate luminescent material, optionally with a blue light-emitting phosphor, in the vicinity of a near UV/blue LED. Blue light-emitting phosphors that may be used in embodiments of the present inventions are Sr4Al14O25:Eu2+, Sr6P6BO20:Eu2+, BaAl8O13:Eu2+, (Sr,Mg,Ca,Ba)5(PO4)3Cl:Eu2+, and Sr2Si3O6.2SrCl2:Eu2+.
