Abstract: The semiconductor light emitting device of the present invention emits a blue light component, a green light component, and a red light component. The blue light component is a light component emitted by a first solid light emitting element that emits light having an emission peak in a wavelength range of 430 nm to less than 490 nm, the green light component is light emitted by a second solid light emitting element that emits light having an emission peak in a wavelength range of 360 nm to less than 420 nm that is converted into wavelength-converted light by a green phosphor, and the red light component is light emitted by at least one solid light emitting element selected from the first solid light emitting element and the second solid light emitting element that is converted into wavelength-converted light by a red phosphor. The green phosphor emits green light on the basis of an electronic energy transition of Mn2+.
