Patent ID: 8884512

Claim:
A white light emitting lamp, comprising: a board; a semiconductor light emitting element on the board, which emits ultraviolet light or blue light; and a light emitting portion comprising a blue phosphor, a green phosphor, and a red phosphor, which are excited by light emitted from the semiconductor light emitting element to respectively emit blue light, green light, and red light, and a deep red phosphor that comprises a manganese-activated magnesium fluorogermanate phosphor of formula (5): αMgO·βMgF 2 .βMgF 2 .(Ge 1-x Mn x )O 2 (5) wherein α, β, and x are numbers that respectively satisfy 3.0≦α≦4.0, 0.4≦β≦0.6, and 0.001≦x≦0.5, said deep red phosphor having a main emission peak in a longer wavelength region than a main emission peak of the red phosphor, wherein the light emitting portion covers a light emitting surface of the semiconductor light emitting element, wherein the lamp emits white light by mixing light emission colors from the blue phosphor, the green phosphor, and the red phosphor, and wherein the average color rendering index Ra of said white light emitting lamp is 96 or more.
