  • Patent number: 8425052
    Abstract: The invention relates to an illumination system (100), a projection device, and a color wheel (20, 22, 24). The illumination system comprises a light source comprising a first light-emitting unit (50) and a second light-emitting unit each emitting light towards a light output window (110). The illumination system comprises the color wheel including a spoke (40) between two adjacent color segments. The system is configured to prevent the spoke when transiting the optical path (80) between the light source and the light output window to simultaneously transit a first optical path between the first light-emitting unit and the light output window and a second optical path between the second light-emitting unit and the light output window. The illumination system further comprises a drive unit (92) which is configured for switching off the first light-emitting unit during a time interval (p1) when the spoke transits the first optical path.

  • Patent number: 8414134
    Abstract: An illumination apparatus includes first and second light source units. An optical axis converting element has a first surface that reflects a luminous flux emitted from the first light source unit and a second surface that reflects a luminous flux emitted from the second light source unit and is configured to reflect respective luminous fluxes emitted from the respective light source units in substantially one direction. Each of the luminous fluxes entering the optical axis converting element has different dimensions in two directions orthogonal to each other in a plane orthogonal to an emission axis of the each light source unit. The optical axis converting element is arranged such that a cross-sectional shape of the luminous flux entering each optical axis converting element taken along the surface has a short side direction in the same direction as the direction of arrangement of the first and second surfaces.
