A LED lighting system for reading multiple data matrix codes on device populated transport media with a line scan camera, includes a light housing, a plurality of LED circuit bars, having a plurality of LEDs, mounted to an inner surface of the light housing arranged to provide high angle lighting and low angle lighting and a light controller operatively connected to the light housing to selectively control the light intensity, the light distribution and the angle of the LEDs on each of the plurality of LED array bars, whereby the LED lighting system can reduce texture noise and detect contrast in color or contrast in texture on the device populated transport media. The LED lighting system includes a device cooling system having an air compressor for cooling the LEDs such that they can operate at an optimal level.
