Illumination device for simulating neon lighting through use of fluorescent dyes

An illumination device, comprising:

• a plurality of light-emitting diodes emitting light of a predetermined first color;
• and
• a light color conversion system, including
• a light-receiving surface positioned adjacent said light-emitting diodes,
• a light-emitting surface, and
• one or more fluorescent dyes, each of said dyes emitting light of one or more predetermined wavelengths following absorption of light from said light-emitting diodes and from other of said fluorescent dyes, wherein light observed along the light-emitting surface of said light color conversion system is perceived as having a color different than the predetermined first color of light emitted by said light-emitting diodes.

An illumination device, comprising:

• a light source;
• an intermediate light-transmitting medium extending along and positioned adjacent said light source, said intermediate light-transmitting medium being tinted with a predetermined combination of one or more fluorescent dyes;
• and
• a substantially rod-like member having a predetermined length with a light-receiving surface and a light-emitting surface, said member being composed of a material that has both optical waveguide and light scattering properties, and the light-receiving surface of said rod-like member being positioned adjacent said intermediate light-transmitting medium;
• wherein light emitted from said light source and having a first perceived color is partially absorbed by the predetermined combination of fluorescent dyes of said intermediate light-transmitting medium, such that light transmitted through said intermediate light-transmitting medium to the light-receiving surface of said rod-like member has a second perceived color resulting from a collective light of multiple wavelengths;
• and
• wherein the optical and light scattering properties of said rod-like member result in an elongated light intensity pattern on the light-emitting surface of said rod-like member along said predetermined length.

An illumination device, comprising:

• an intermediate light-transmitting medium extending along and positioned adjacent said light source, said intermediate light-transmitting medium being tinted with a predetermined combination of one or more fluorescent dyes;
• and
• a substantially rod-like member having a predetermined length with a light-receiving surface and a light-emitting surface, said member being composed of a material that has both optical waveguide and light scattering properties, and the light-receiving surface of said member being positioned adjacent said intermediate light-transmitting medium;
• wherein light of a predetermined wavelength is emitted from said light source and is partially absorbed by the predetermined combination of dyes of said intermediate light-transmitting medium and causes each of said dyes to emit light of a particular wavelength, such that light transmitted through said intermediate light-transmitting medium to the light-receiving surface of said rod-like member is a collective light of multiple wavelengths;
• and
• wherein the optical and light scattering properties of said rod-like member result in an elongated light intensity pattern on the light-emitting surface of said rod-like member along said predetermined length.
