Patent ID: 7573190

Claim:
A visible light emitting device, comprising at least: a semiconductor light emitting element configured to emit bluish purple or blue light; a support member formed with a depression for placing said semiconductor light emitting element therein, said depression constituted as a visible wavelength light reflective surface; terminals configured to supply electric power to said semiconductor light emitting element; and a phosphor configured to absorb a part or the whole of light emitted from said light emitting element, and to emit fluorescence at a wavelength different from that of the absorbed light, the phosphor including X % of a first fluorescent material configured to emit green, yellowish green, or yellow light, and Y % of a second fluorescent material configured to emit yellowish red or red light, at a mixing ratio meeting a condition of 0≦X<100, 0<Y≦100, and 0<X+Y≦100, wherein said second fluorescent material comprises a CaAlSiN 3 crystal phase including, dissolved therein in a solid state, one or more element(s) selected from Mn, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu.
