Spectroradiometer

LPCE-2 is an Integrating Sphere Spectroradiometer System for identifying the performance of individual LED and LED lamp. LED's quality should be tested by checking its photometry , color and electric parameters. According to LM-79 and CIE request to measure SSL products, it recommend to use an array spectroradiometer with integrating sphere and photometer head. LISUN GROUP developed LPCE-2 test system for LED products.

Measures:
• Electrical: forward voltage, reverse voltage, forward current, reverse current
• Photometric: total luminous flux, luminous efficiency, Radiant. Iv.
• Colorimetric: total radiant intensity, dominant wavelength, peak wavelength, color coordinates, half-bandwidth, spectral purity, correlated color temperature (CCT), color rendering index (CRI).

Features:
• Chromaticity coordinate, correlated color temperature, rending index
• Different models for the UV-VIS and VIS-NIR spectral range wavelength: 380nm ~ 780nm (Special: 200nm-1050nm)
• Spectral Resolution: ±0.2nm, Reproducibility: ±0.5nm
• λ Spectral radiation bandwidth
