<p><P>PROBLEM TO BE SOLVED: To allow comfortable illumination to be always carried out regardless of illumination intensity of a lighting system, in a dimming system. <P>SOLUTION: By using two light sources having color temperatures different from each other such as a fluorescent lamp 12 having a color temperature of 8,000 K and a fluorescent lamp 13 having a color temperature of 3,000 K, a ratio of the illumination intensity of the fluorescent lamp 12 (high color temperature) to that of the fluorescent lamp 13 (low color temperature) is increased by a control means 30 as the illumination intensity adjusted by an adjustment means 20 is increased so that the total color temperature of the lighting system 10 is controlled to be set high to set a combination of the light intensity and the color temperature in a range allowing a human being to feel comfortable, whereby illumination is always brought into a comfortable state regardless of the total illumination intensity of the lighting system 10. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
