<P>PROBLEM TO BE SOLVED: To increase the reflected light inside a tubular body and the radiation range of illumination light from the tubular body. <P>SOLUTION: An LED fluorescent illumination apparatus 7 can provide LED illumination instead of a straight tube fluorescent lamp and divides the inside of the tubular body into an LED lighting illumination room and a power source room with an inner wall 6. In the LED fluorescent illumination apparatus, the tubular body 1 is composed of a first tubular body 2 made of a translucency synthetic resin or the like and a second tubular body 3 as a metal product made of a metal having a circular arc in a transverse section view, an inner wall having a horizontal plane and a pair of inclined planes is located inside the tubular body with the horizontal plane positioned closer to the second tubular body side than the tubular body center, LED light-emitting devices and phosphor are mounted on the upper surface of the horizontal plane of the inner wall, a power source circuit is mounted on the lower surface of the horizontal plane, light guide diffusers are mounted on the inclined planes, fluorescent light is radiated from almost all the surface of the inner wall to the first tubular body, and reflection light from the first tubular body is diffusely reflected at an LED light-emitting illumination room, for a radiation range to be expanded to an installation surface side. <P>COPYRIGHT: (C)2011,JPO&INPIT |
