Problems solved by technology

[0004] The purpose of the present invention is to provide a method for calibrating and retesting LED spectrometers. Through the application of this method, inaccurate test data, low pass rate and problems of inaccurate test data and low pass rate during machine operation due to deviations in spectrometer calibration are solved. The test accuracy is reduced and the consistency is poor after the spectrometer works for a long time

Abstract

The present invention discloses a method for the calibration and re-test of an LED beam splitter. The method includes the six steps of standard lamp fabrication, beam splitter parameter setting, single-bead correction, multi-bead confirmation, initial workpiece verification and timed re-test. According to the method of the invention, standard ED lamp beads are scientifically selected to correct a beam splitter on a production line, and therefore, the accuracy of beam splitting test data in subsequent production operation can be ensured, the qualification rate of products and the reliability of data can be improved, the number of the times of rework caused by test error can be reduced, and the improvement of production capacity and production efficiency can be favored; and the stability of the production operation of the beam splitter can be ensured, the differences of LED lamp beads in the same data classification interval can be decreased, and the consistency of the products can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of LED production, in particular to a method for calibrating and retesting an LED spectrometer. Background technique [0002] In the later stage of LED packaging, it is necessary to use a spectrometer to test and classify the semi-finished products produced in batches. The spectrometer is mainly used to test the photometric, chromaticity and electrical parameters, and then the materials in the same photometric, chromatic and electrical parameter range are screened and processed. together. Before each batch of LED semi-finished products needs to be split, the spectrometer must be calibrated first to ensure the accuracy of the spectroscopic test. Before the spectrometer performs the calibration operation, a standard LED lamp bead must be prepared. The LED standard lamp bead has the standard value of the corresponding spectroscopic parameter and the rated spectroscopic test working current. The standard lamp s...
