Abstract

The invention discloses a lighting fixture of a backlight source and defect detection equipment using the same, and relates to the technical field of detection of backlight sources. The lighting fixture is used for solving the problems of the lighting fixture in the prior art of numerous development categories, long development period and high development cost. The lighting fixture of backlight source disclosed by the invention comprises a fixture body, wherein a detection area for placing the backlight source is arranged on the fixture body; a bracket is further fixed on the fixture body, a longitudinal adjusting rod is arranged on the bracket, a horizontal adjusting rod is movably connected to the longitudinal adjusting rod, and a pressure head is fixed at one end of the horizontal adjusting rod; the longitudinal adjusting rod can move up and down along the bracket to drive the horizontal adjusting rod to move up and down, and the horizontal adjusting rod can move front and back, left and right in the horizontal direction to drive the pressure head to move in the detection area. The lighting fixture disclosed by the invention is mainly applied to the detection of backlight sources with medium and small sizes.

Description

technical field [0001] The invention relates to the technical field of detection of backlight sources, in particular to a lighting fixture for backlight sources and defect detection equipment using the same. Background technique [0002] The backlight is a light source located behind the liquid crystal display, and its luminous effect directly affects the visual effect of the liquid crystal display. In the manufacturing process of the backlight, impurities, stains, or scratches are sometimes unavoidable. Therefore, in order to ensure the high quality of the backlight, it is necessary to carry out relevant inspections on the backlight, such as lighting detection. [0003] Specifically, the lighting detection of the backlight usually means that the gold finger on the flexible circuit board in the backlight is in close contact with the conductive sheet of the external power supply through the pressure head in the lighting fixture, so as to energize the flexible circuit board th...
