The invention discloses a multi-angle line
light source for detection, which comprises a plurality of strip line light sources, line light fixing plates arranged at both ends of the strip line
light source for fixing, and fan fixing plates arranged on both sides of the line light fixing plate 1. A cover plate is provided on the top of the line light fixing plate. There are cooling fans on the fan fixing plate and the cover plate. The fan fixing plate and the line light fixing plate form a downward light-emitting gap. Both ends of the board, the base plate is attached with a heat dissipation
silicone grease sheet, and the heat dissipation
silicone grease sheet is attached to a PCB board. There are many high-power
LED lamp beads on the PCB board. The inner cavity of the
light source has a cylindrical condenser lens at the opening of the inner cavity of the line light source, the end plate is fixedly connected with the line light fixing plate, and the center line of the cover plate has a camera detection through hole. The invention has better light concentrating effect, stronger light and higher brightness, and is more conducive to the lighting detection of various defects of
mobile phone screens and the surface of PCB boards, etc., and has better detection effect.
