Color-changing illumination device
First Claim
1. 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 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 and/or emitted from the independent sections of the intermediate member.

Abstract
An illumination device for simulating neon or similar lighting is generally comprised of a rod-like member, a housing, a light source, and an intermediate light-transmitting medium extending along and positioned adjacent the light source with a light-receiving surface for receiving light emitted from said light source and a light-emitting surface for emitting light into the rod-like member. This intermediate light-transmitting medium is preferably composed of a matrix of a substantially translucent acrylic, polyurethane, or similar material tinted with a predetermined combination of one or more fluorescent and/or phosphorescent dyes. The intermediate light-transmitting medium is subdivided into independent sections, each of which is provided with differing combinations of fluorescent dye, phosphorescent dye, and/or no dye at all.

18. An illumination device, comprising:
-
a plurality of point light sources;
a diffracting 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 diffracting element, said intermediate member being subdivided into independent sections along the length of said diffracting 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 diffracting 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 diffracting element is a combination of the light being passed through and/or emitted from the independent sections of the intermediate member. - View Dependent Claims (19, 20)

21. 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 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 plurality of point light sources and a light-emitting surface for emitting light into said diffusing element, each of said dyes emitting light of a predetermined hue following absorption of light from said plurality of point light sources;
wherein the plurality of point light sources is arranged in at least two separate and independently controlled strings; and
wherein a collective light ultimately emitted along a visible surface of said diffusing element has a hue resulting from a combination of light emitted from the first string of point light sources, the second string of point light sources, or both strings, along with light emitted from dyes of said intermediate member. - View Dependent Claims (22, 23, 24)
