Light emitting device |
abstract |
A light emitting device that is capable of achieving excellent color rendering property is provided. The light emitting device contains a light emitting element having a light emission peak wavelength within a range of 430 nm or more and 470 nm or less, and a fluorescent member. The fluorescent member contains a first fluorescent material that contains an Eu-activated alkaline earth aluminate, a second fluorescent material that contains a Mn-activated fluorogermanate, a third fluorescent material that contains a Ce-activated rare earth aluminate, and a fourth fluorescent material that contains an Eu-activated silicon nitride having Al and at least one of Sr and Ca. |
