  • Publication number: 20200081332
    Abstract: An illumination system, a projection apparatus and an illumination control method are provided. The illumination system includes an excitation light source, an optical component, a light source driver, a temperature sensing module and a controller. The excitation light source emits an excitation light beam. The optical component is located on a transmission path of the excitation light beam. The light source driver is configured to drive the excitation light source. The temperature sensing module is located in a neighboring region of the optical component and configured to sense a temperature of the neighboring region of the optical component to output a sensing voltage. The controller is configured to receive the sensing voltage to determine whether the sensing voltage falls out of a predetermined voltage range and configured to output a control signal to the light source driver to adjust the excitation light beam.

  • Publication number: 20200073221
    Abstract: A projection device, a light source system and a projection method thereof are provided. A portion of the light-emitting units are controlled to provide a light beam as the first light beam. It is detected whether characteristic parameters of the light-emitting units providing the light beam reach a preset value. When the preset value is not reached, the light-emitting units providing the light beam are disabled, and the remaining light-emitting units are controlled to provide the back-up light beam as the first light beam. A portion of the first light beam is converted into a second light beam. The first light beam of which the wavelength is not converted and the second light beam are combined to generate an illumination beam. The illumination beam is converted into an image beam. The image beam is converted into a projection beam.

  • Patent number: 7922343
    Abstract: A lens-shifting device including a base, two fixing rods, a sliding plate, a first and a second gear set is provided. The sliding plate is slidably mounted on the fixing rods via the fixing rods. A lens is fixed on the sliding plate and the sliding plate has a rack disposed on one side thereof. The first gear set has a first gear and a worm gear co-axial therewith. One of the fixing rods passes through the first gear such that the first gear and the worm gear may rotate relative to the fixing rod. The second gear set having a worm wheel and a second gear co-axial therewith is disposed between the fixing rod and the rack. The worm gear is for driving the worm wheel and the second gear is used for driving the rack such that the sliding plate moves relative to the fixing rods.

  • Patent number: 7507006
    Abstract: A lamp receptacle of a projection apparatus includes a receptacle body defining a receiving space, and having a peripheral wall and an upper opening. The peripheral wall is formed with an aperture. A fixing element is attached securely to the peripheral wall above the aperture, and protrudes into the receiving space. A filter glass is disposed in the receiving space behind the aperture in the peripheral wall. A holding frame is disposed behind the filter glass, and has a central hole aligned with the aperture. A mounting arm has a vertical section integrally formed with an upper section of the holding frame, and a horizontal section extending frontward from the vertical section to overlap and fasten the upper fixing element, thereby retaining the holding frame in such a manner to urge the filter glass to abut against the peripheral wall around the aperture.
