  • Patent number: 10775685
    Abstract: A projector, comprising a housing (100) and a machine body provided inside the housing (100). A supporting piece (200) is connected to the housing (100) via a connection mechanism, and the supporting piece (200) can be converted between a first position and a second position under the limiting action of the connection mechanism. The supporting piece (200) is attached to a surface of the housing (100) at the first position, and a projection element is triggered at the same time to enable the machine body to be in a first working state. The supporting piece (200) departs from the surface of the housing (100) at the second position and drives the housing (100) to change a projection elevation thereof with respect to a horizontal plane, and the projection element is triggered at the same time to enable the machine body to be in a second working state, thereby controlling the working states of the machine body on the premise of free adjustment of a projection angle.

  • Patent number: 10372026
    Abstract: An optical fixing device includes light source fixing parts for fixing a plurality of solid state light sources, a second light combination element fixing part for fixing at least one second light combination element, a condenser lens fixing part for fixing a condenser lens, and second reflecting mirror fixing parts arranged in accordance with at least part of the plurality of solid state light sources for fixing second reflecting mirrors. The second light combination elements are used for transmitting some light emitted from the solid state light sources and is not reflected and/or are used for reflecting light reflected by the second reflecting mirrors. The condenser lens is used for converging the light passing through the second light combination elements. The optical fixing device is compact in size and shape with low production cost, providing high accuracy for the relative positioning of the optical elements.

  • Patent number: 10209607
    Abstract: Disclosed is a projector (1), comprising a projector body (10) with a lens (12), and a light reflection assembly (20) for adjusting a projecting direction of the lens (12). The light reflection assembly (20) comprises a reflective mirror (23), and the light reflection assembly (20) is provided to be rotatably connected with the projector body (10). During the rotation, a mirror face of the reflective mirror (23) always faces towards the lens (12), so that the reflective mirror (23) adjusts the angle of the projecting direction between the mirror face and the lens (12) with the rotation of the light reflection assembly (20), so as to adjust the projecting location of the lens (12) by means of the rotation of the reflective mirror (23), such that the projecting direction can be changed without moving the projector (1).
