Wavelength converting device and light emitting device using the same
The wavelength converting device includes a substrate and a wavelength converting member disposed on the substrate. The wavelength converting member includes a fluorescent material powder and a binder binding the fluorescent material powder. An upper surface of the wavelength converting member serves as a light emitting surface which includes upper surfaces of the fluorescent material powder and an upper surface of the binder. The binder has first recesses formed adjacent to the fluorescent material powder in the upper surface of the binder.
