Method for testing five-surface light-emitting CSP LED

The invention discloses a method for testing a five-surface light-emitting CSP LED , which comprises the following steps of: (1) arranging the CSP LED on a white film, and testing a color temperaturevalue, namely a first color temperature value, of the CSP LED; (2) rearranging the CSP LEDs on the first matrix, and testing the color temperature value of the CSP LEDs, namely a second color temperature value; (3) taking the second color temperature value as label data, constructing a feature vector by using the first color temperature value, adding the label data to the feature vector to obtaina data set, and dividing the data set into a test set and a training set; and (4) training the random forest model by using the training set, correcting the test set by using the trained random forestmodel to obtain an accuracy rate, adjusting parameters of the random forest model according to the accuracy rate, and taking the parameter with the highest accuracy rate as the parameter of the random forest model.
