High Precision Spectroradiometer Sphere LED Testing Equipment

LPCE-2 is an Integrating Sphere Spectroradiometer LED Testing System for identifying the performance of single LEDs and LED lamps. LED's quality should be tested by checking its photometric, colorimetric and electrical parameters. According to CIE127-1997, IES LM-79-08 and IES LM-80-08, it recommends to using an array spectroradiometer with integrating sphere to test SSL products. The LPCE-2 system is applied with a CCD Spectroradiometer (LMS-8000 or LMS-9000) and worked with A molding integrating sphere with testing holder base function which will be more circle and the test results will be more accurate than the traditional integrating sphere.
