A portable-sized full-color LED illumination panel and a Palm-sized Controller were developed. In addition to 3 primary color (red, green, and blue) LED, white LED was used in order to achieve high illuminance in the white illumination region and to facilitate realization of pastel colors. A mobile computer was used as the controller. Adjustment of illuminance is performed through the duty ratio control device connected to the computer. By using this controller system, 4 types of LED could be controlled according the input 3 information (Chromaticity Coordinates and light intensity) by a real-time calculation. Up to 255 illumination panels can be connected. This system allows individual control of a maximum of 255 illumination panels, or control of all illumination panels using the same illumination conditions. By using this system, 9 types of illumination colors were selected and some characteristics were measured. For every illumination, the chromaticity coordinates hardly changed above the duty ratio above 30%.
