An illumination device for simulating neon or similar lighting uses fluorescent dyes, thus allowing for emission of light in colors that cannot ordinarily be achieved by use of LEDs alone. Such an illumination device is generally comprised of an elongated diffusing member enclosing a string of continuously mounted LEDs. An intermediate light-transmitting medium including a predetermined combination of one or more fluorescent dyes is interposed between the light source and the diffusing member, such that light from the LEDs is partially absorbed by each of the fluorescent dyes, and a lower-energy light is then emitted from each of the fluorescent dyes and into the light-receiving surface of the diffusing member, producing a substantially uniform light along the light-emitting surface of the diffusing member with perceived a color different than that of the LEDs.
