Patent ID: 7011421

Claim:
An illumination device, comprising: a light source emitting light of a predetermined first hue; a substantially rod-like member having a predetermined length and positioned adjacent said light source, said member being composed of a material that has both optical waveguide and light scattering properties so as to preferentially scatter light along the length of said rod-like member; and an intermediate member generally composed of a matrix of light-transmitting material and one or more light-fluorescing dyes, said intermediate member including a light-receiving surface for receiving light emitted from said light source and a light-emitting surface for emitting light into said rod-like member, each of said light-fluorescing dyes emitting light of a predetermined wavelength following absorption of light from said light source, wherein a collective light ultimately emitted from said rod-like member is of a second hue with a substantially uniform intensity along the length of said rod-like member.
