LED Characteristic Test Apparatus Video


Fully characterize LED characteristics


This Apparatus included photometric, electricity, chroma and thermal 4 modules. These are classic experiments on LED characteristics:



Professional curriculum and courseware

In accordance with international standards and national standards designed LED measurements, the measured parameters is complete, contains common physical concepts and industrial parameters. The curriculum written by professor, which is refer to the contents of relative photoelectric experiments materials, Like academic papers, dissertations.


Specialty instrument

The key items like Power supply, constant current power supply, integrating Sphere, Radiometer, Temperature Controller Chamber are cooperated with professional LED Measurement Company, Not only meeting the teaching purpose, and also to maintain the function, accuracy and reliability standards.

1set spectrometer included in this Apparatus, It is also scientific and industrial grade. In addition to this experiment, but also can be applied independently associated with spectral and colorimetric measurement experiments.

Computer-based interactive educational Learning software

The software base on the Concept of computer-based learning, Emphasis on learning process and interaction,Guide students to learn the relevant knowledge step by step.

Typical experiments and data

1. Feature of electricity and light conversion


Forware and reverse V-I curve


2. Light spatial distribution




Average intensity vs current curve in 1D


Light spatial distribution curve in 2D


3. Relationship between current, flux and luminous efficiency







Current vs flux curve


Current vs luminous efficiency curve


4. Chromatic parameters




Chromatic parameters


5. Thermal characteristic



The module is used to measure and calculate LED’s K coefficient, thermal resistance and junction temperature. The software can real-time display the Voltage vs Time curve, and analyze the thermal resistance and junction temperature in a steable state


Little current’s K coefficient testing
