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 pro-perties including electrical

photometric and colorimetric characteristics be measured automatically and conti-nuously. 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.
