Abstract
An illumination device is provided, which includes, in series, a fluorescing radiation source, a light selective filter, and a light source. The light selective filter is relatively transmissive of fluorescing radiation and relatively reflective of light. The light source is preferably a fluorescable phosphor. The illumination device further includes in series after the light source, a fluorescing radiation selective filter which is relatively transmissive of light and relatively reflective of fluorescing radiation. The illumination device may be one of several specific devices, such as a fluorescent lamp assembly, a flat panel display backlight assembly, or a white light-emitting diode assembly.
