Abstract: An illumination device includes a first light source, a second light source, and a light-diffusing medium. The first light source emits light of a first hue, and the second light source emits light of a second hue. The light-diffusing medium receives light emitted from the first and second light sources. The light-diffusing medium is composed of a light-transmitting material and a light color-converting material. The light color-converting material is selected to convert the light of a first hue into a light of a third hue, and to pass the light of the second hue with substantially no conversion. The light-diffusing medium thus emits light of a perceived hue that is a combination of the light of the third hue and the light of the second hue. By adjusting the relative intensities of the light emitted by the first and second light sources, the perceived hue can be readily transformed or tuned.

Abstract: An illumination device has an elongated array of point light sources, a focusing rod, and a diffusing rod. The focusing rod is positioned adjacent and along the array of point light sources, for focusing light into an elongated light distribution pattern. The diffusing rod is positioned adjacent and along the focusing rod for receiving the focused light and diffusing the light into an essentially uniform light intensity distribution pattern, for simulating a tubular lamp having a uniform light intensity distribution. The illumination device may further have a color-converting member for converting a light of a first color emitted by the array of point light sources to a light of a second color, such that the light emitted by the illumination device is of a color that is a combination of the light of a first color and the light of a second color.

Abstract: An illumination device for use in daylight conditions includes a light-diffusing member provided with one or more dyes and a light source extending along and positioned adjacent a light-receiving surface of the light-diffusing member, with the light source emitting light that is substantially unabsorbed by the dyes as it passes through the light-diffusing member. Accordingly, in daylight conditions, the dyes are activated by sunlight to emit light such that light perceived along a light-emitting surface of the light-diffusing member is a combination of light from said light source and light from the dyes, thus increasing the output of the illumination device in daylight conditions.

Abstract: A lighting system includes a helical light-transmitting fiber and an LED. The helical light-transmitting fiber is doped with a first wavelength converting material and defines a helical axis. The LED has a light-emitting portion for emitting light of a first color. The LED is aligned axially with the first helical fiber such that a portion of any light emitted by the LED will pass through the open space between the turns of the first helical fiber and a portion of any light emitted by the LED will be received by the first helical fiber and converted to light of a second color. Adjustment of the compression of the helical fiber will adjust the mixture of colors in the light emitted by the system. Further, the relatively small cross-sectional area of the fiber serves to lessen any dye migration in the fiber.

Abstract: An illumination device has a light-transmitting member formed in the shape of a toroid having a light-receiving surface and a light-emitting surface, the light-transmitting member defining a central axis, a light source located along the light-transmitting member central axis, and a light-directing housing for guiding light from the light source into the light-receiving surface of the light-transmitting member. The light-transmitting member may have optical waveguide and light-scattering characteristics, whereby the light-transmitting member emits light having a substantially uniform intensity along the light-emitting surface. The light-directing housing has a top reflector member and a bottom reflector member positioned on opposing side of the light source and cooperating with the light-transmitting member such that light is emitted only through the light-transmitting member.

Abstract: An illumination device has a light source, a waveguide, and a light-transmitting medium. The light source emits light of a first color. The waveguide has both optical waveguide and light scattering properties. The light-transmitting medium is composed of a matrix of substantially translucent material doped with a pigment, and is positioned between the light source and the waveguide such that a portion of the light emitted by the light source passes around the light-transmitting medium and reaches the waveguide directly, and a portion of the emitted light is received by the light-transmitting medium. The pigment changes a portion of the received light to a light of a second color. The waveguide receives and mixes the light of the first color and the light of the second color, and emits light of a combined color.

Abstract: An illumination device for simulating neon lighting comprising a plurality of space point light sources positioned adjacent a lateral light receiving surface of a substantially rod-like waveguide made of a material that preferentially scatters light entering the light receiving surface such that the light intensity pattern exiting a lateral light emitting surface of the waveguide has a substantially uniform light intensity pattern.

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.

Abstract: An illumination device simulates neon lighting using a light source for emitting light of a predetermined first hue and a light-transmitting medium having a predetermined density of phosphorescent dye positioned adjacent to the light source. The phosphorescent dye will absorb light emitted by the light source and emit light of a second hue. An observer of the device perceives light that is of a hue that is different from the predetermined first hue. A means for varying the intensity of the light emitted by the light source creates color changing effects in the illumination device. Light-emitting diodes (LEDs) are a suitable light source. A waveguide having both optical waveguide and light scattering properties is used to diffuse the combined light and simulate the uniform appearance of a neon tube. Alternatively, the waveguide itself can be doped with phosphorescent dye to emit light having the perceived hue.
