This invention provides a method for testing the color of LED emission. It involves using a camera to capture an image of the LED illuminated on a test background. The color of the image within the analysis area corresponding to the LED represents the color of the LED under test. This image is then analyzed using color analysis software and compared with the standard color of the LED to determine if its emission color conforms to the factory specifications. The entire process requires no manual intervention, minimizing errors and increasing efficiency. Furthermore, this method requires only a standard camera, test background, and color analysis software, resulting in extremely low system cost and applicability to various LED manufacturers.
