<P>PROBLEM TO BE SOLVED: To provide a light-emitting device capable of restraining the deterioration of the light-emission efficiency of a fluorescent body, due to the temperature rise of the fluorescent body and attaining greater outputting of an optical output. <P>SOLUTION: The light-emitting device comprises a flexible board 1, an LED chip (light-emitting diode element) 2 mounted on one surface side of the flexible board 1; a color conversion member 4, made of a sheet-shaped light-transmitting member, including a fluorescent body wherein light with a color different from the light-emitting color of the LED chip 2 is emitted on the one surface of the flexible board 1 by being excited by the light emitted from the LED chip 2; and a heat-radiating member 5, arranged on the other surface side of the flexible board 1 and serving as a support member for supporting the flexible board 1. The flexible board 1 is bent so that the light emitted from the LED chip 2 is incident on the surface of the color conversion member 4 from the inclined direction, and the whole surface is jointed to the heat-radiating member 5. <P>COPYRIGHT: (C)2009,JPO&INPIT |
