Abstract:
A method for manufacturing a light emitting device includes: mounting a first light emitting element whose emission peak wavelength is in a range of 430 nm to 490 nm and a second light emitting element whose emission peak wavelength is in a range of 490 nm to 570 nm; and providing a light transmitting member including a red phosphor and at least one of a green phosphor of which a half width of an emission spectrum is not more than 45 nm and a blue phosphor of which a half width of an emission spectrum is not more than 60 nm. The step of providing the light transmitting member includes adding at least one of a predetermined amount of the green phosphor and a predetermined amount of the blue phosphor based on the emission peak wavelength of the second light emitting element.
