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.
