1. A machine vision inspection system, comprising:

  • an inspection stage configured for moving an object under test;

    a linear image capture module configured for grabbing an image of the object under test; and

    a light source module configured for providing light beams to the linear image capture module, and the light source module comprising;

    a plurality of linear light emitting diode (LED) light sources configured for providing the light beams, each of the linear LED light sources comprising a plurality of LEDs, luminance of the linear LED light sources being determined by the number of rows of the linear LED light sources, the length of each of the linear LED light sources and the cooperation of the LEDs with the same or different colors, wavelengths or sizes; and

    a lampshade having a semi-cylindrical inner space, the interior of the lampshade being a semi-circular curved surface with an upward opening or a downward opening, a first disposing area and a second disposing area in the interior of the lampshade being located at both sides of the longitudinal axis of the semi-cylindrical lampshade, the linear LED light sources being disposed symmetrically in the first disposing area and the second disposing area, intervals between each two adjacent linear LED light sources in the first disposing area and the second disposing area being the same, a linear field of view of the linear image capture module being served as a reference axis, each of the linear LED light sources being disposed at a relative included angle relative to the reference axis, and an arranging direction of each of the linear LED light sources being the same with an extending direction of the semi-circular curved surface.
