<P>PROBLEM TO BE SOLVED: To reduce color unevenness in a light-emitting device which emits light by mixing light in multiple colors. <P>SOLUTION: A light-emitting device 1 comprises: a plurality of LEDs 3; a first translucent member 4 which mutually covers the LEDs 3; and a light-converting member 5 which directly covers a light-extracting surface of the first translucent member 4. The light-converting member 5 includes: regions each corresponding to the LEDs 3 and having a fluorescent material 6 which converts the wavelength of light emitted from the LEDs 3; and regions free of the fluorescent material 6. Light from the LEDs 3 and incident onto the regions having the fluorescent material 6 is emitted after being subjected to wavelength conversion by the fluorescent material 6. Light from the LEDs 3 and incident onto the regions free of the fluorescent material 6 is emitted as it is without being subjected to wavelength conversion. Thus, color unevenness of the emitted light can be reduced by appropriately setting the arrangement of the light-converting member 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
