Zusammenfassung: | An illumination device in dudes a luminescent concentrator with a waveguide having a radiation converter element distributed in the waveguide, and a solid state light source configured to irradiate a radiation input face of the waveguide. The radiation converter element is configured to absorb at least part of the light source radiation and to convert into radiation converter element radiation, wherein the concentration of the converter element in the waveguide is at least three times higher than necessary to absorb 98% of the light source radiation over the width of the waveguide. |
