Patent ID: 7077979

Claim:
A light emitting semiconductor device, comprising: a GaN based light emitting diode that emits light having a wavelength in the range of 200 nm to 620 nm; a red phosphor that absorbs light of a wavelength in the range of 240 nm to 550 nm and emits red light at a wavelength in the range of 580 nm to 700 nm, having the formula: Bi x Ln 1−x VO 4 :A where x is 0.05 to 0.5, Ln is an element selected from the group consisting of Y, La and Gd, and A is an activator selected from Eu 3+ , Sm 3+ and Pr 3+ , or any combination thereof, with or without Tb 3+ as a co-dopant; a green phosphor; and a blue phosphor.
