Control of color primaries and white point in a laser-phosphor projector
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 includes a first blue laser source emitting a first beam in a fourth waveband, the first blue laser source having a first lase...

| description | 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 includes a first blue laser source emitting a first beam in a fourth waveband, the first blue laser source having a first laser driver, a second blue laser source emitting a second beam having a central wavelength and a fifth waveband, the second blue laser source having a second laser driver, a substrate having a wavelength conversion element for emitting light 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 and a beam combiner for combining the combined first beam and the converted beam, which combination results in a white beam. Dichroic losses can be reduced by using a green phosphor together with red laser assistance. |
