<P>PROBLEM TO BE SOLVED: To perform light control based on an HLS color space by a full-color LED to improve a point to be a problem on use. <P>SOLUTION: Hue is dimmed by hue diffusion control in which diffusion control is developed by a full-color LED. Based on separate control arrays output by the hue diffusion control and brightness diffusion control, an intermediate color of colors by the control arrays is output by intermediate color control for arranging the control arrays by dispersion in a longer period in comparison with a diffusion period. The hue diffusion control and the intermediate color control make three components of the color such as the hue, chroma, and brightness adjustable for every component to execute light control based on an HLS color space close to human sensations. In addition, single color LEDs to be lit in dimming are restricted to one to raise an adjustment function of the color, and to simultaneously improve a point that used current is large in comparison with that of a simplex unit of a single color LED, and badness of reproducibility of the color due to difference of some characteristic of the LED. <P>COPYRIGHT: (C)2013,JPO&INPIT |
