<P>PROBLEM TO BE SOLVED: To provide a light-emitting device and a lighting fixture capable of uniformly mixing colors of light with different wavelengths with a loss suppressed. <P>SOLUTION: The device is provided with a color-mixing unit 2 arranging five light guide members 20<SB>1</SB>to 20<SB>5</SB>formed in a shape of rotation symmetry on concentric circles. Therefore, light with different wavelengths emitted from a light source unit 1 (blue-color light, red-color light, and green-color light) is mixed while it is guided by the light guide members 20<SB>1</SB>to 20<SB>5</SB>of the color-mixing unit 2, and is emitted outside through a support member 21, so that light with different wavelengths can be uniformly mixed. Moreover, a loss of light can be suppressed as compared with a conventional case in which light is diffused with the use of a diffusing member. Since color mixing is thus uniformly made, color shading is hardly generated even if light is condensed by a lens part 21a provided at the support member 21. <P>COPYRIGHT: (C)2008,JPO&INPIT |
