METHOD FOR EVALUATING THE SOUNDNESS OF LED HEAT SINK BY PASSIVE INFRARED THERMOGRAPHY

摘要

The present invention relates to a method for evaluating an integrity of an LED heat sink by using passive infrared thermal imaging and, more specifically, relates to a method for evaluating an integrity of an LED heat sink by using passive infrared thermal imaging in which passive infrared thermal inspection is enabled to check for defects of LED heat sinks produced during an automated manufacturing process having irregular shapes in real-time, thereby saving time and costs when compared to visual inspection. According to the present invention for the method for evaluating the integrity of the LED heat sink by using passive infrared thermal imaging, a heat sink surface of an LED lighting is scanned with a thermal camera to check whether the heat sink is defective when the LED lighting module is powered on.
