<p><P>PROBLEM TO BE SOLVED: To solve a problem that LED light sources have not made use of their intrinsic other features, although they brought forth LED light sources akin to conventional light sources. <P>SOLUTION: The illumination unit 20 is provided with a light-emitting part 21, a light analysis part 31, a controller 51, and a first communication interface 41. The light-emitting part 21 and the light analysis part 31 are housed in a housing with a transparent window. The light-emitting part 21 contains a plurality of groups of LEDs, each group emitting light with a different spectrum. The light analysis part 31 generates luminance signals related to luminance of light generated by each group and luminance of light coming from a place outside the housing. The controller 51 adjusts currents flowing in each LED in accordance with the luminance signals. The first communication interface 41 is made use of by the controller 51 in order to receive commands by communicating with external devices of the illumination unit 20 during operation of the same 20. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
