<P>PROBLEM TO BE SOLVED: To provide an LED illumination device having an unconventionally superior effect. <P>SOLUTION: As for the illumination device 10 using an LED as a light source, a light source unit 30 is arranged in a direction nearly perpendicular to a light trace light-shade reflecting surface 11 by a reference of a perpendicular starting point of a side of the light trace light-shade reflecting surface 11 of the illumination device 10, an acute angle is set by having the side of the light-shade reflecting surface as the starting point, obtusely to the light trace light-shade reflecting plate 11, an irradiation light 20 is irradiated on an uneven face 12 of the light trace light-shade reflecting plate 11 from both opposing sides of the light trace light-shade reflecting plate 11 obtusely to the light trace light-shade reflecting plate 11, a reaching light reflecting cover 14 is installed at a regular-reflected light beam, the regular-reflected light is reflected again on a protective plate 17 or the light trace light-shade reflecting plate 11, and the large illumination device making the most of the irradiated light is provided. <P>COPYRIGHT: (C)2011,JPO&INPIT |
