    摘要： [Problem] To provide a projector having a simple optical system for preventing relative inversion of illuminance distribution in left-right direction while preventing decrease in illuminance.
    [Means for Resolution] The projected images of the illumination optical system 30 each corresponding to each color light passing through each of the optical paths OP1, OP2 and OP3 can be formed at the positions of the corresponding liquid crystal display panels 61g, 61r and 61b such that the images are not inverted to one another without increasing the number of lens over the conventional relay optical path configuration. Also, the magnification of the images of the illumination optical system 30 formed at the positions of the liquid crystal display panels 61g, 61r and 61b can be equalized by previously controlling the relative image forming conditions of the first and second paths OP1 and OP2 having lengths different from each other. This can reduce deterioration of white balance and color unevenness in the projected image on the projector 10 even when the light emission distribution of the light source varies with time, for example.

    摘要： The present invention is directed to an illumination system. The illumination system comprises a plurality of modules such that each module comprises a plurality of light emitting diodes (LEDs) adapted to emit light. The illumination system further comprises a plurality of lens elements disposed subsequent to the LEDs. Further, a number of the lens elements corresponds to a number of LEDs; such that the plurality of lens elements is adapted to redirect the light emitted by the LEDs on a plurality lenses. The illumination system further comprises a plurality of imagers disposed subsequent to the plurality of lenses, such that each of the imagers forms an image from the light provided by each of the lenses, respectively. Further, the images formed by the plurality of imagers are combined by a device, such as an X-cube, to form a single image that is further provided to a light pipe of a display system.

    摘要： The present invention relates to a method of generating light with a predetermined chromaticity value of a color gamut by color mixing of the light emitted by a plurality of light sources, each of which emits light with a primary color, the light sources being capable of emitting light with at least three primary colors, wherein at least a first and a second light source are used to emit light of at least one primary color. The object to provide a simple method of generating light with a predetermined and constant chromaticity value of a color gamut by color mixing of the light emitted by a plurality of light sources, which can even be advantageously used in display applications sequentially displaying primary colors, is achieved in that said first and said second light source emit light with different peak and/or dominant wavelengths, the chromaticity of the primary color generated by color mixing of the light emitted from said first and said second light source being adjusted to a predetermined and constant chromaticity value by controlling the ratio of intensities of said first and said second light source, and said chromaticity value of said primary-color light generated by color mixing is used to generate light by color mixing with the light of other primary color light sources.
