<P>PROBLEM TO BE SOLVED: To provide a light-emitting device in which the occurrence of chromaticity deviation caused by a change in ambient temperature is suppressed. <P>SOLUTION: In the light-emitting device including a light-emitting element, and a phosphor which absorbs at least a part of light emitted from the light-emitting element and emits light having a different wavelength, the phosphor includes a first phosphor which emits light in a green region from an yellow region, and a second phosphor which emits light in a red region, and light-emitting output reduction rates of the first phosphor and the second phosphor with respect to temperature elevation are approximately equal. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
