20140016297 | Light Module for a Projection Apparatus and Method for Generating the Blue Component in a Light Module for a Projection Apparatus - A light module for a projection apparatus, comprising a laser apparatus adapted to emit linearly polarized radiation in the blue wavelength range, a luminous wheel arranged in the beam path of the radiation emitted by the laser apparatus, a first beam splitter arranged in the beam path of the radiation emitted by the laser apparatus between the laser apparatus and the luminous wheel, a focusing apparatus arranged in the beam path of the radiation emitted by the laser apparatus between the first beam splitter and the luminous wheel, and at least one polarization manipulation apparatus, adapted to rotate the polarization of radiation that has passed through it twice in different directions through 90°, wherein the first beam splitter is arranged such that it is also located in the beam path of radiation in the blue wavelength range which has passed twice through the polarization manipulation apparatus in different directions. | 01-16-2014 |
20140029237 | ILLUMINATION APPARATUS WITH PHOSPHOR WHEEL - Various embodiments propose an illumination apparatus having a laser apparatus and a phosphor wheel, wherein the phosphor wheel has, in addition to at least one phosphor region for phosphor conversion, at least one transmission region for colored light having a second, greater dominance wavelength from a light source. The beam paths from light source and laser apparatus are e.g. arranged collinearly, wherein the phosphor wheel rotates into the common optical axis of the laser apparatus and light source. By adding colored light having a greater dominance wavelength, the dominance wavelength of a colored light channel that is required for projection applications can also be obtained with colored light converted using efficient phosphor having a dominance wavelength that is too small. | 01-30-2014 |
