LED Comprehensive Characteristic Measurement (Comprehensive Upgrade Version)

The experiment is rich in content and comprehensively covers the four most important characteristics of LED - light, electricity, color and heat. It is the most basic theoretical knowledge required for the compulsory courses of optoelectronics majors in universities.

Several experiment modules are independent of each other but also mutually supportive. The function divisions of the components are clearly defined, making it easy for students to understand.

The components of the experimental device and the software design are all designed according to the standards of teaching products. The operation settings comply with teaching requirements, and the software functions are complete, including knowledge navigation, independent test modules, which enable students to have a clear logical thinking and easy understanding when using it, achieving the effect of deepening theoretical learning.

The principle of parameter testing strictly follows the current authoritative testing standards in China and abroad. For example: the average light intensity test adopts the CIE average light intensity test standard conditions; the luminous flux test adopts the integrating sphere method; the junction temperature measurement adopts the pulse current method. This method has the advantages of simplicity, non-destructiveness, accuracy and good transient response.
