ABSTRACT:
A lighting device having a light source, light pipe, and a light-dispensing element is disclosed. The light source emits light at a first wavelength and transmits that light to the light pipe. The light dispensing emitter includes an extended section coupled to the light pipe that emits light along the extended section, the extended section having a side surface through which light exits from the extended section. The extended section can include a medium that is transparent to light of the first wavelength and a plurality of scattering centers, the extended section having a shape such that light that is not scattered by the scattering centers is trapped within the extended section by internal reflection. The extended section can also include a light conversion material that converts light of the first wavelength to light of a second wavelength.
