Patent ID: 7186005

Claim:
An illumination device, comprising: a plurality of point light sources; a diffusing element having a predetermined length and positioned adjacent said plurality of point light sources; and an intermediate member interposed between said plurality of point light sources and said diffusing element, said intermediate member extending the length of said diffusing element, and said intermediate member being subdivided into independent sections along the length of said diffusing element, a selected number of said independent sections being tinted with a combination of one or more dyes, said intermediate member including a light-receiving surface for receiving light emitted from said a plurality of point light sources and a light-emitting surface for emitting light into said diffusing element, each of said dyes emitting light of at least one predetermined wavelength following absorption of light from said plurality of point light sources, wherein a collective light ultimately emitted along a visible surface of said diffusing element is a combination of the light being passed through or emitted from the independent sections of the intermediate member.
