Integrating Sphere with Side Assistant Opening
IS-*MA**P/IS-*MA**C
According to IES LM-79 Clause 9.1.2, it request the 4π geometry configuration and 2π geometry Integrating Sphere for the LED Testing. Lisun Group developed the integrating sphere with side assistant Opening in A Molding Technology to meet the requirements.• Painting material of integrating spheres is according to CIE Pub.No.84 (1989) • The painting material is BaSO4 coating: ρ (λ) ≥0.96 (450nm~800nm) and ρ (λ) ≥0.92 (380nm~450nm) • Fine diffuse reflection: Reflectance ρ≈0.8 and accuracy of ρ (λ) <1.5% • Build-in all functional lamp testing jigs: the vertical is for E40/E27, the horizontal is for T5/T8/T12 tubes and the Testing Holder Base for LED street luminiares. All of the testing jigs can allow the lamp be tested up and down in the sphere. • Power Cable, Power Terminal and Auxiliary lamp position has been built-in (Auxiliary lamp is option). • Two photo detector ports, one optical fiber port and temperature sensor hole are built-in • Ordering Code: IS-1.5MA55P or IS-1.5MA55C (Φ1.5m, IS-1.5MA55P means square side opening is 0.5×0.5m, IS-1.5MA55C means cycle side opening diameter is 0.5m). IS-1.75MA66P or IS-1.75M66C (Φ1.75m and side opening is 0.6m). IS-2.0MA77P or IS-2.0MA77C (Φ2.0m and side opening is 0.7m). • Other size such as diameter 2.5m, 3.0m can be special order according to customer’s request

High Precision Spectroradiometer Integrating Sphere System
LPCE-2(LMS-9000)
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-9000B or LMS-9000A) 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.
