Abstract:
A light emitting device, comprising a light emitting element having a peak emission wavelength in a range of from 440 nm to 460 nm, and a phosphor member. The phosphor member contains: a first phosphor having a peak emission wavelength in a range of from 440 nm to 550 nm and comprising at least one selected from the group consisting of an Eu-activated alkaline earth aluminate or an Eu-activated silicate containing Ca, Mg, and Cl; a second phosphor having a peak emission wavelength in a range of from 500 nm to 600 nm and comprising a Ce-activated rare earth aluminate; a third phosphor having a peak emission wavelength in a range of from 610 nm to 650 nm and comprising an Eu-activated silicon nitride containing Al and at least one selected from the group consisting of Sr and Ca; and a fourth phosphor having a peak emission wavelength in a range of from 650 nm to 670 nm and comprising a Mn-activated fluorogermanate.

Claim (Index 12):
