<P>PROBLEM TO BE SOLVED: To provide a light-emitting apparatus capable of easily obtaining light emission of desired chromaticity while suppressing deterioration in color rendering performance. <P>SOLUTION: The light-emitting apparatus has a blue light emitting element for emitting a blue light, and a phosphor layer coated on the blue light emitting element and including a phosphor to be excited with the blue light to emit a single color light other than the blue light, and has a spectrum in which the light emission density in a peak wavelength of the blue light is ≤35% of the light emission density in a peak wavelength of the phosphor. Alternatively, the light-emitting apparatus has a near-ultraviolet light-emitting element for emitting a near-ultraviolet light and a phosphor layer coated on the ultraviolet light-emitting element and including a phosphor to be excited with the near-ultraviolet light to emit a single color light, and has a spectrum in which the light emission density in a peak wavelength of the near-ultraviolet light is ≤35% of the light emission density in a peak wavelength of the phosphor. <P>COPYRIGHT: (C)2009,JPO&INPIT |
