LED Integrating Sphere Spectroradiometer System

LPCE-2(LMS-8000) is an Integrating Sphere Spectroradiometer LED Measurement 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 CIE 177, CIE84,  CIE-13.3 , IES LM-79, Optical-Engineering-49-3-033602, IESNA LM-63-2, ANSI-C78.377 and IES LM 79-08 standards, it recommends using an array spectroradiometer with integrating sphere and photometer head to test SSL products. LISUN developed LPCE-2 test system for LED products.

LMS-8000AS is updated version for LMS-8000A, LMS-8000AS can connect two integrating spheres at the same time. That’s mean LMS-8000AS be switch between the two spheres conveniently, but no need to take out the detector cable and optical fiber between the big sphere and small sphere.
