<p><P>PROBLEM TO BE SOLVED: To provide an illumination device providing information about chromaticity and color temperature so that users can select, capable of variously providing color lights of corresponding color temperatures and color phases to chromatic coordinate values on a provided chromaticity diagram, and not only for educational usage for understanding a system to chromaticity, but also improving convenience of users for producing various illuminating environments in accordance with surroundings, illuminance and psychological status. <P>SOLUTION: The illumination device includes a chromaticity selecting part providing various color temperatures and chromaticity so that users can select, a light-emitting part with a plurality of light-emitting elements arrayed so as a color light with mutually different color phases to be selectively emitted, a memory part with driving pattern data of the light-emitting elements stored so as to be corresponded with chromaticity and color temperatures capable of being selected by the chromaticity selecting part, and a control part for controlling drive of the light-emitting part with the use of the driving pattern data stored in the memory part so that the light corresponding to the chromaticity and the color temperature selected by the chromaticity selecting part is emitted. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
