Claim 0:
1. A wavelength-converting member comprising:
a wavelength-converting layer having an upper surface, a lower surface, and one or more lateral surfaces with the upper surface having a surface area smaller than a surface area of the lower surface, and 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 of the wavelength-converting layer, the wavelength-converting layer including
a thermally conductive part, and
a fluorescent material containing part in contact with the thermally conductive part;

a heat-dissipating component on which the wavelength-converting layer is mounted, the heat-dissipating component defining at least one threaded hole;
a securing member having a second inclined surface in contact with and pressing the first inclined surface such that the wavelength-converting layer is secured to the heat-dissipating component, the securing member defining at least one through hole; and
at least one screw inserted through the at least one through hole and fitted in the at least one threaded hole so that the securing member is secured to the heat-dissipating component by the at least one screw.
