  • Patent number: 8662677
    Abstract: A projection apparatus, an illumination module and a brightness adjusting method for the projection apparatus are provided. The projection apparatus comprises the illumination module and the actuator. The illumination module comprises a luminous element. First, the actuator drives the luminous element to move from the first position to the second position to detect the first brightness and second brightness generated by the luminous element. When the first brightness is higher than the second brightness, the actuator is adapted to drive the luminous element to the first position. Thereby, the brightness of a projection image generated by the projection apparatus can be adjusted to an optimal value.

    Abstract: A light beam adjusting device includes a housing having a reflector, a light device disposed within the reflector for generating light which may be reflected partially upwardly and partially downwardly by the reflector. The light reflected downwardly by the reflector is allowed to emit out through the housing. A shielding panel is disposed in the housing, and an actuating device may rotate the shielding panel to open and block the lower portion of the housing, and to selectively open and block the light reflected upwardly by the reflector. The light reflected upwardly by the reflector may form a high beam together with the downwardly reflected light when the housing has not been blocked by the shielding panel.

  • Patent number: 8562150
    Abstract: A projection type display apparatus in which an inclination and a positional deviation of optical axes among a plurality of light sources can be easily corrected to obtain a high quality projection image. Green, blue and red laser beams emitted from light sources are converted into collimated beams by condenser lenses, and the positions and angles of the optical axes of the beams of the three colors are evaluated by position detection imaging device and angle detection imaging device, respectively. The positions and angles of the light sources are adjusted by respective actuators so that the positions and angles of the optical axes match each other. Consequently, the laser beams emitted from the light sources can be combined with high accuracy to thereby realize a high definition projection type display apparatus.
