  • Patent number: 8833946
    Abstract: A light source module and a projection apparatus are provided. The light source module includes a first light-emitting device, a wavelength conversion device, a second light-emitting device and a light combination device. The first light-emitting device emits an exciting beam. The wavelength conversion device is disposed on a transmission path of the exciting beam, and converts the exciting beam into a first color beam. The wavelength conversion device is suitable for moving, so that the exciting beam illuminates into different positions of the wavelength conversion device at different time. The second light-emitting device emits a second color beam. Colors of the first color beam and the second color beam are different. The light combination device is disposed on transmission paths of the first color beam and the second color beam, and combines the first color beam and the second color beam.

  • Patent number: 8545032
    Abstract: A light source module and a wavelength conversion module are provided. The light source module includes a first light emitting device, a reflection unit, a wavelength conversion unit, a second light emitting device and a light combination unit. The first light emitting device emits an exciting beam. The reflection unit is disposed on a transmission path of the exciting beam. The wavelength conversion unit is disposed on the reflection unit and located on the transmission path of the exciting beam. The exciting beam is obliquely incident into the wavelength conversion unit along an optical axis of the first light emitting device, and the wavelength conversion unit converts the exciting beam into a first color beam. The second light emitting device emits a second color beam. The light combination unit is disposed on transmission paths of the first color beam and the second color beam.

  • Patent number: 8496333
    Abstract: An illumination module including a light emitting element, a wavelength conversion unit, a control unit, and a determining unit is provided. The light emitting element is capable of emitting an excitation light beam. The wavelength conversion unit is disposed on a transmission path of the excitation light beam for converting the excitation light beam into a color light beam. The control unit is connected to the wavelength conversion unit and capable of driving the wavelength conversion unit to rotate and to shift relative to the excitation light beam. The determining unit is electrically connected to the control unit. When the determining unit determines that a shifting condition is satisfied, the determining unit instructs the control unit to shift the wavelength conversion unit relative to the excitation light beam, so as to change the irradiation position of the excitation light beam on the wavelength conversion unit.
