Patent ID: 6936857

Claim:
A lighting apparatus comprising: a semiconductor light source emitting radiation having a wavelength in the range of about 430 nm; a phosphor blend comprising Sr 4 Al 14 O 25 :Eu 2+ (SAE) and a second phosphor having the formula(Tb 1-x-y A x RE y ) 3 D z O 12 , where A is a member selected from the group consisting of Y, La, Gd, and Sm; RE is a member selected from the group consisting of Ce, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, and Lu; D is a member selected from the group consisting of Al, Ga, and In; x is in the range from 0 to about 0.5, y is in the range from about 0 to about 0.2, and z is in the range from about 4 to about 5; the phosphor blend radiationally coupled to the semiconductor light source; wherein the phosphor is capable of absorbing the radiation emitted by the semiconductor light source and converting the radiation into white light.
