Light emitting device
Abstract:
A light emitting device includes a light emitting element to emit a first light having a first peak wavelength. A second wavelength converting member contains a second phosphor to convert the first light into a third light having a third peak wavelength longer than the first peak wavelength and shorter than a second peak wavelength. The second wavelength converting member includes a portion in which the second wavelength converting member has a first concentration of the second phosphor at a height of an upper surface of the light emitting element in a height direction and a second concentration of the second phosphor at a height of a lower surface of the light emitting element in the height direction. The second concentration is higher than the first concentration such that the second phosphor reflects the second light.
