Patent ID: 8519611

Claim:
A white light emitting device comprised of a first LED having a peak emission in the range 400 to 480 nm and a phosphor material radiationally coupled to said first LED, said phosphor material comprising a phosphor having a general formula of [(Sr 1−z M z ) 1(x+w) A w Ce x ] 3 (Al 1−y Si y )O 4+y+3(x−w) X 1−y−3(x−w) , wherein 0<x≦0.10 and 0≦y≦0.5, 0≦z≦0.5, 0≦w≦x, A is Li, Na, K, Rb, or any combinations thereof, M is Ca, Ba, Mg, Zn, or any combinations thereof, and X is a monovalent anion; a second LED having a peak emission in the range >615; and a third LED having a peak emission in the range of 580 to less than 610 nm and wherein said second LED has a peak emission between 35 and 40 nm greater than said third LED.
