| titleOfInvention | Control of color primaries and white point in a laser-phosphor projector |
| abstract | The invention relates to a light projection system for generating an image with three primary colors, each primary color being respectively defined by a first, second and third wavebands. The system comprises a first blue laser source (5) emitting a first beam (5') in a fourth waveband, said first blue laser source (5) having a first laser driver (4), a second blue laser source (3) emitting a second beam (2') having a central wavelength and a fifth waveband, said second blue laser source (3) having a second laser driver (2), a substrate having a wavelength conversion element (8) for emitting light (2'') at a plurality of wavelengths after absorption of a light beam at an excitation wavelength within a fifth waveband of the second blue laser source (3) and a beam combiner (11) for combining the combined first beam and the converted beam (2''), which combination results in a white beam (14). Dichroic losses can be reduced by using a green phosphor together with red laser assistance. White point and color primaries can be controlled by using a variable green waveband reduction filter and/or by using a multi-band color sensor (22) and a controller (24) for deriving driving levels for the drivers of the laser sources. |
