Integrating sphere test system

时间:2022-01-09

Thanks to our customers of the long year support, we decide to open our lab.

Any old or new customer, we can provide free test service for two times and issue the relative test report.

Test subject as below Light source analysis test and Spatial intensity distribution test.


Light source analysis test

Item:CMS-3000S Spectroradiometer + integrating sphere test system


Testing environment:Standard optics lab .

The system including:Spectroradiometer、Integrating sphere,WL serial CC&CV DC Power source、CHP Serial AC Power source,Digital Power meter、Standard lamp(Traced to NIM ).


Introduction:

The system adopts the world advanced holographic concave gratin, precision optical system,the electronic shutter control technology and CCD linear array detector. It has low stray light, wide linear dynamic range, high repeatability, high stability, millisecond test speed and high accuracy.

 Relative standards:

>IES LM 79-08 Electric and photometric measurements of SSL products(Recommend CCD type spectroradiometer+ integrating sphere test system)

>GB/T24824-2009 Test methods for LED modules for general lighting applications


Tested parameters:

(1)Photometric parameters:The luminous flux, luminous efficiency, radiation power

(2)Colorimetric parameters: The relative spectral power distribution Pλ、chromaticity Coordinate (x,y),(u,v)、CCT Tc、CRI Ra、SDCM、Peak wavelength λp、Spectral half width Δλ、 Main wavelength λd、Color purity etc

(3)Electric parameters:Forward voltage, forward current, reverse voltage, constant current, voltage, current, power, power factor, etc.
