ABSTRACT:
An illumination device simulates neon lighting and allows for emission of light in colors that cannot ordinarily be achieved by use of LEDs alone through the incorporation of a light color conversion system into the illumination device. This light color conversion system comprises an intermediate light-transmitting medium tinted with a predetermined combination of one or more fluorescent dyes. Light emitted from the light source of the illumination device is directed into the intermediate light-transmitting medium and interacts with the fluorescent dyes contained therein. This light is partially absorbed by each of the fluorescent dyes of the intermediate light-transmitting medium, and a lower-energy light is then emitted from each of the fluorescent dyes and into the light-receiving surface of the waveguide. Thus, selection of appropriate combinations of dyes results in various colors being emitted from the illumination device.
