Abstract
Provided is a light emitting device that is characterized by at least combining a solid-state light emitting element, a first wavelength converter, and a second wavelength converter, and emits output light. The solid-state light emitting element emits primary light. The first wavelength converter absorbs at least part of the primary light and converts this part of the primary light to first wavelength-converted light. The second wavelength converter absorbs at least part of first mixed light including first transmitted primary light, which is the primary light that has passed through the first wavelength converter, and the first wavelength-converted light, and converts the light to second wavelength-converted light. The output light includes at least transmitted first wavelength-converted light, which is a light component obtained by the first wavelength-converted light having passed through the second wavelength converter, and a light component of the second wavelength-converted light.
