High Precision Spectroradiometer Integrating Sphere System

LPCE-2 High Precision Spectroradiometer Integrating Sphere System is an integrated platform from LISUN for the comprehensive analysis of light sources. It is available in two configurations: the LPCE-2 (LMS‑9000C) for advanced industrial applications and the LPCE-2 (LMS‑9500C) for scientific-grade requirements. The system features an integrally molded integrating sphere equipped with a specimen mount, offering superior measurement accuracy compared to traditional multi-piece (segmented) integrating spheres. It enables the simultaneous measurement of photometric, colorimetric, spectral, and electrical parameters for various light sources, including LEDs, energy-saving lamps, fluorescent lamps and HID (high-intensity discharge) lamps. The test results comply with both domestic and international lighting standards, making the system ideal for R&D prototyping, quality control on production lines, and third-party laboratory certification testing.

Test Parameters:
• Chromaticity Parameters: Chromaticity coordinates, correlated color temperature (CCT), color ratios, peak wavelength, full width at half maximum (FWHM), dominant wavelength, color purity, color rendering index (CRI), CQS, TM-30-24 (Rf, Rg), spectral distribution, etc.
• Photometric Parameters: Luminous flux, luminous efficacy, radiant power, WPE, EQE, EEI, energy efficiency class, pupillary flux, pupillary flux efficacy, pupillary factor, PAR (for horticultural lighting), PPF, etc.
• Electrical Parameters: Voltage, current, power, power factor, frequency; displacement factor (DF) and harmonics (LS2050)
• LED Luminous Flux Maintenance Testing: Luminous flux vs. time, CCT vs. time, CRI vs. time, power vs. time, power factor vs. time, current vs. time, luminous efficacy vs. time
