Abstract
An illumination device includes a solid waveguide; a plurality of light emitting diodes emitting light of different colors and arranged to project light into at least one of the surfaces of the waveguide; and one or more phosphor materials for converting light emitted by one of the LEDs from one color to another, such that an out-coupling region of the waveguide outputs a mixture of light from at least some of the LEDs and light converted by the phosphors materials.
