<P>PROBLEM TO BE SOLVED: To provide a light-emitting device which has a semiconductor light-emitting element as a light source and has heat radiating fins hardly collecting moisture and duct, and a lighting fixture equipped with this light-emitting device. <P>SOLUTION: The light-emitting device 1 includes an outline member 3 of which at a large diameter part 13 on one end side 3a, a light-emitting body 2 having a semiconductor light-emitting element 8 is installed, and which has a base 40 at the other end side 3b, a lighting device 4 which is housed in at least one of the outline member 3 and the base 40, is operated by being supplied with power through the base 40, and lights the semiconductor light-emitting element 8, a plurality of heat radiating fins 5 which are installed radially in the circumferential direction of the outline member 3 along one end side 3a to the other end side 3b of the outline member 3 so that the outside face 3d of the other end side 3b of the outline member 3 rather than the large diameter part 13 may be exposed continuously in the circumferential direction of the outline member 3, and a translucent enclosure 6 which is installed in the large diameter part 13 of the outline member 3 to cover liquid-tight the light-emitting body 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
