摘要:
A light source device includes a first light source configured to emit light within a first wavelength band, a light-source light production section configured to sequentially produce light-source light of a plurality of colors at predetermined frequency by using light emitted by the first light source, a second light source configured to emit light within a second wavelength band different from the first wavelength band, and a light source control section configured to control drive timing for each of the first and second light sources such that a light emission period for light-source light using light emitted by the second light source is positioned between light emission periods for the light-source light of the plurality of colors produced by the light-source light production section and that the light-source light using light emitted by the second light source has a frequency higher than that of the light-source light production section.
摘要:
To provide a light source unit which can increase luminance and a projector including this light source unit. This light source unit includes a luminous wheel having a segment area on which a luminescent material layer is formed which emits light of a predetermined wavelength band by receiving light, and a segment area which is made into a transmission portion which transmits light, a primary light source which shines light of a visible wavelength band on to the luminous wheel, a secondary light source which emits light of a wavelength band which is different from light from the luminescent material layer and light from the primary light source, a collective optical system which collects light from the luminous wheel and the secondary light source to cause them to converge to the same optical path, and a light source control device which controls the emission of light from the light sources.
摘要:
A light source unit including an excitation light source for emitting light in a blue wavelength band, a fluorescent wheel, a light emitting device for emitting light in a red wavelength band and a light guiding optical system for guiding light emitted from the fluorescent wheel and the light emitting device to a light guiding device. The fluorescent wheel has a fluorescent area where a green fluorescent material layer for emitting fluorescent light in a green wavelength band is disposed and a diffuse area for converting light emitted from the excitation light source into diffuse light of which directivity is weak are disposed end to end in a circumferential direction. A concentration of weight content of the green fluorescent material and a thickness thereof are such that a luminescent intensity of fluorescent light emitted from the green fluorescent material layer is enhanced.
