Abstract
Application of high brightness LED as the light source for colors to the electric display or lighting equipment is expected.
The simple circuit, which can handle from 1 to 10 LED of various colors driven in the most suitable state without changing a circuit constant, is proposed. We obtained how to mix varied colors emitted from LED, and the generation of patterns on indicator by the color materials such as ink and paint. We produced electric display experimentally in order to confirm visibility of color or luminosity of mixing of various colored light.
The display constituted with a light guide and indicator, a number of LED was installed in the side or in the backside of the light guide. Indicator is placed upon an upper side of the light guide. The letter, which was drawn on an indicator urface with green ink, twinkles by the luminous flux of LED of blue beautifully.
