YTR-6302 # LED Comprehensive Characteristics Test Experiment

SUMMARY

This set of experimental system adopts modular structure design, can provide electrical characteristics, light spatial distribution characteristics, photometric, chromatic characteristics and thermal characteristics of a total of four modules of test experiments, covering the electrical, optical, color, thermal and related characteristics of LED parameters test experiments. During the experiment, students can select several components of the system to build the experimental setup and test the characteristics of certain aspects of LED according to their needs. Test setup and control through special software operation, in a humanized human-computer interaction software experimental interface, real-time mapping of LED voltage - current, luminous flux - current, luminous intensity - current, light spatial distribution of the characteristic curve. In order to make professional teaching and actual production closely integrated, the system test parameters are selected with reference to the course syllabus and combined with important industrial parameters, and the test principle is based on the current authoritative test standards at home and abroad.
