Linear lighting systems and methods. In one example, two or more lighting elements having an essentially linear or curvilinear shape are coupled together to form a lighting system. Each lighting element includes a group of LEDs arranged so as to illuminate the essentially linear or curvilinear shape of the lighting element. Each element may include LEDs to generate the same color light, and / or LEDs to generate light of different colors. Additionally, each element may include one or more controllers to control the LEDs so as to create a variety of temporal and / or color-oriented lighting effects. The controller(s) may employ one or more of a variety of control techniques to control the LEDs, such as those involving analog control signals or pulse-width modulated (PWM) control signals. The lighting elements of the system may each be configured as a “stand alone” unit working within the system, producing respective lighting effects that may or may not be coordinated with each other. Alternatively, two or more elements of the system may be configured as addressable lighting elements to facilitate coordination of the elements as a networked lighting system. Any of the foregoing linear lighting systems may be used in a variety of interior or exterior, as well as direct or indirect, lighting applications. In one example, such lighting systems are particularly well-suited as replacements or substitutes for neon lighting installations.

An illumination device includes an elongated and substantially cylindrical waveguide, which has a light-emitting outer surface and an interior semi-reflective portion spaced at a predetermined distance from the light-emitting outer surface. A channel is defined through a portion the waveguide along the length thereof and is adapted to receive an elongated light source such that emitted light is directed into at least one of the wall surfaces defined by the channel. As the light enters and is directed about the circumference of the waveguide, a portion of the light is scattered and emitted through the light-emitting outer surface of the waveguide. Light is also reflected by the semi-reflective portion, causing additional light to be scattered and emitted through the light-emitting outer surface of the waveguide. The result of this guiding, reflecting, and emission of light is a substantially homogenous and uniform light intensity pattern over the light-emitting outer surface of the waveguide so as to simulate neon lighting.

The device may have a waveguide member and a housing, creating a cuttable illumination device for simulating neon lighting.

An illumination device simulates neon lighting and allows for emission of light in colors that cannot ordinarily be achieved by use of LEDs alone through the incorporation of a light color conversion system into the illumination device. This light color conversion system comprises an intermediate light-transmitting medium tinted with a predetermined combination of one or more fluorescent dyes. Light emitted from the light source of the illumination device is directed into the intermediate light-transmitting medium and interacts with the fluorescent dyes contained therein. This light is partially absorbed by each of the fluorescent dyes of the intermediate light-transmitting medium, and a lower-energy light is then emitted from each of the fluorescent dyes and into the light-receiving surface of the waveguide. Thus, selection of appropriate combinations of dyes results in various colors being emitted from the illumination device.

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.

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.
