<P>PROBLEM TO BE SOLVED: To provide an illumination device using light emission bodies like LED, excellent in light condensing property or parallelizing property, capable of obtaining brilliant illumination light. <P>SOLUTION: A plurality of LED chips L<SB>1</SB>to L<SB>7</SB>are mounted on a supporting member 11 at regular intervals and the supporting member 11 is made to slide in high speed. The light from the LED chips is irradiated on an area to be irradiated by condensing the light and controlling passage of the light by optical lenses 17, 18 arranged on a light emission front face of the LED chips located at a prescribed standard light emission position 16, by making only the LED chip passing through the prescribed standard light emission position 16 emit light. By making the LED chips L<SB>1</SB>to L<SB>7</SB>successively repeating this movement, even if the light emitted from the LED chips L<SB>1</SB>to L<SB>7</SB>is time divisional, almost continuous illumination light in appearance is obtained. <P>COPYRIGHT: (C)2007,JPO&INPIT |
