摘要： A lamp includes a light-emitting body that converts electric energy into light energy and a translucent glass covering the light-emitting body, wherein a phosphor layer is provided on at least inner or outer surface of the translucent glass. The phosphor layer includes a fluorescent material including a first phosphor that at least partially converts energy emitted by an excitation source, which emits ultraviolet having a wavelength of about 365 nm, to a first emission spectrum that is different from the energy, and a second phosphor that at least partially converts the first emission spectrum to a second emission spectrum. Peak wavelengths of the emission spectrum of the first and second phosphors have a relation of complementary colors so that when the light created due to the peak wavelengths of the first and second phosphors are mixed, the resulting light is in the white region.

摘要： An object of the present invention is to provide a light emitting device which emits light of deep yellowish color with high luminance. The light emitting device of the present invention comprises a light emitting element having a peak emission wavelength shorter than 490 nm, a fluorescent material for wavelength conversion which absorbs light from the light emitting element and emits light of a wavelength longer than that of the light from the light emitting element, and a filter which cuts off a part of a mixed light produced by mixing the light of the light emitting element and the light of the fluorescent material, wherein the light transmitted through the filter has a chromaticity coordinate on the chromaticity diagram according to CIE 1931 plotted in a region defined by a first point (x=0.450, y=0.450), a second point (x=0.250, y=0.650), a third point (x=0.350, y=0.750) and a fourth point (x=0.250, y=0.750) and in the region defined by a closed curve consisting of the monochromatic locus and the purple boundary.
