Claim 10:
11. A light emitting device comprising:
a wavelength-converting layer having an upper surface, a lower surface, and one or more lateral surfaces with each of the one or more lateral surfaces of the wavelength-converting layer defining a first inclined surface inclined at an acute angle with respect to the lower surface, the wavelength-converting layer including
a first part made of sintered ceramics, and
a second part in contact with the first part and containing fluorescent material;

a heat-dissipating component on which the wavelength-converting layer is mounted;
a securing member secured to the heat-dissipating component, the securing member having a second inclined surface pressing the first inclined surface such that the wavelength-converting layer is secured to the heat-dissipating component; and
at least one light source configured to irradiate light on the second part.
