Abstract：With the rapid popularization of LED technology,it's application in optics has expanded from lighting to many fields,such as landscape,intelligent interaction and vehicle display.The requirements of various fields are different,and the detection of optical performance is also paying more and more attention to high quality and precision.The quality control of optical testing laboratory is the core content to ensure the accuracy and effectiveness of testing results.This paper systematically studies the quality control methods of lighting testing laboratory,and focuses on the implementation strategies ofexternal quality control and internal quality control.In terms of external quality control,based on CNAS-CL01:2018"Accreditation criteria for testing and calibration laboratory competence"and CNAS-RL02:2023"Rules for proficiency testing",this paper discusses the appropriate test items and implementation frequency requirements for competence verification and inter laboratory comparison;In the internal quality control,the existing standards for detection methods do not provide the evaluation basis for comparison.This paper introduces the technical specifications and operation processes of three common methods:personnel comparison,equipment comparison and quality control chart.Through the comprehensive use of internal and external quality control methods,the detection ability of the laboratory for new optical requirements is effectively improved,and the validity and reliability of the experimental results are ensured.The research in this paper provides a theoretical basis and practical guidance for the construction of the quality management system of optical testing laboratory,and helps the laboratory realize the coordinated development of standard compliance and technological innovation.
