High Precision Spectroradiometer Integrating Sphere System for LED Light Measurement

LPCE-2 Integrating Sphere Spectroradiometer LED Testing System is for single LEDs and LED lighting products light measurement. LED's quality should be tested by checking its photometric, colorimetric and electrical parameters. According to CIE 177, CIE84,  CIE-13.3, IES LM-79-19, Optical-Engineering-49-3-033602, IESNA LM-63-2 and ANSI-C78.377, it recommends to using an array spectroradiometer with an integrating sphere to test SSL products. The LPCE-2 system is applied with a CCD Spectroradiometer (LMS-9000C/LMS-9000A) and A molding integrating sphere with holder base. This sphere is more round and the test result is more accruacy than the traditional integrating sphere.
