RGB tester

ZWL-3938 test instrument is suitable for different LED encapsulation of single-chip,double-chip and full color three-chip.  Brief introduction

ZWL-3938 is the only three-chip led test instrument with all independent intellectual property rights at home at present. It adopts the advanced built-in technologyLSIexact numerical control power supply drive and fast data module. Accompanied with X5, you can test and sort with high speed. Also, it can test the photoelectric parameters; and the test condition can be set by computer.

 

Applicable range

ZWL-3938 test instrument is suitable for different LED encapsulation of single-chipdouble-chip and full color three-chip, which adopts the universal interface. With the compatibility of chip probes in most factories and LED test machine, it can test quickly and successfully.

Test parameters

1 Test Vf(0~8V) and Vr(0~200V) with high accuracy;

2 Collocate with our own special accurate constant current source;

3 Provide the card test function of leakage current;

4Draw the related curve of forward voltage and lightening current;

5 Test all optical parameters exactly;

6 Get the test result and sort with high-speed according to self-defined test condition;

7 print, display and store all the data and choose the test condition and range with a computer;

 

Technic character

1 Test the relative spectral power distribution of LED accurately with fast spectrum instrument based on CCD, then you can get the parameters such as    chromaticity coordinatescorrelated color temperaturerendering indexcolor differencepeak wavelengthhalf widthdominant wavelengthcolor ratiocolor purity etc.

2Do the mass data processing and automatisation equipment control with multithreading technology based on WINDOWS.

3 Adopt non-mechanism swift technology, which enhances 12 times of test efficiency and eliminates the manual error completely that makes the error ratio reduce from 3% to 1

4 Use the chief line dummy distributing control technology and NUMA, which converts the test method from SCM to software system, and it can print, display and store mass data by the computer.
