Abstract:
A light emitting device is provided which includes a light emitting element, a phosphor, and a sealing member. The light emitting element has a light emission peak wavelength in the range not shorter than 400 nm and not longer than 460 nm. The phosphor can be excited by light from the light emitting element, and emit luminescent radiation with a light emission peak wavelength in the range in not shorter than 600 nm and not longer than 700 nm. The sealing member includes a pigment for absorbing a part of the light from the light emitting element. X of the light emission chromaticity of the light emitting device falls within the range of x≧0.600 in the chromaticity coordinates in the CIE 1931 color space chromaticity diagram.
