The study on measuring system of LED characteristics based on the high-level image programming language（LabVIEW） was described in this disquisition. The measuring system was designed based on removable guideway, multi-testing locations and computer control, making the comprehensive LED-light-source properties including electrical, photometric and colorimetric characteristics be measured automatically and continuously. This measuring system displays some remarkable merits, such as synthesis, automatization, intergration,continuity and on-line and is further able to improve the efficiency of testing, reliability and accuracy of testing data, results, solving the shortcomings of traditional test methods, such as scattered, low efficiency and high-test errors. The study also introduced design principles of the self-developed system software and elaborated on how to realize the function including the collection of test data, calculation, analysis treatment, etc based on LabVIEW in this measuring system with emphasis. Interrelated experiment data is also attached for demonstrated farther for measuring system.
