    Description

    The LSG-1200A compact goniophotometer system performs precise measurement of luminous intensity distribution curves, photometric intensity data, beam angles, and related parameters for solid-state lighting components including Chip LEDs, LED modules, LED spotlights, and other light sources with beam spread angles ≤180°.

    Optional integration capability: The LSG-1200A can interface with digital power measurement instrumentation (LS2012 DC & AC Power Meter or LS2050 Harmonic Analyzer Power Meter) and the LSP-500VARC AC Power Source for comprehensive electrical characterization.

    Compliance standards: LM-79-19 “Optical and Electrical Measurements of Solid State Lighting Products” EN 13032-1 “Light and lighting – Measurement and presentation of photometric data of lamps and luminaires – Part 1: Measurement and file format; German version EN 13032-1:2004+A1:2012” CIE-121 “The Photometry and Goniophotometry of Luminaires”

    Technical specifications:

    • Conforms to IEC, CIE, and LM-79 standard requirements
    • Automated beam angle measurement: Calculates 1/2 maximum intensity angle, 1/4 maximum intensity angle, 3/4 maximum intensity angle, and 1/10 maximum intensity angle to address specialized testing requirements
    • Output data formatted to international standards (IES, etc.) compatible with lighting design software applications including DiaLux
    • Maximum test specimen dimensions: Φ180mm × 160mm (Diameter × Depth)
    • Luminous intensity measurement range: 0.1–30,000 cd. Detector accuracy: Class A
    • Test distance between specimen and detector: 316 mm or 1000 mm
    • Angular resolution: Horizontal axis: 1°/5°/10°/15°/22.5°/30°/45°/90°, Vertical axis: 0.5°/2°/1.5°
    • Automated rotational capability: Horizontal axis (C): 0°–360°, Vertical axis (Gamma): -90°–+90°
    • Angular measurement accuracy: ±0.2°
    • System expansion: The LSG-1200A can be configured with a CCD spectroradiometer to measure spatial CCT distribution and spectral color parameters. This enhanced configuration is designated as the Goniospectroradiometer System (LSG-1200ACCD). The LSG-1200ACCD Goniospectroradiometer = LSG-1200A Goniophotometer System + LPCE-2 Integrating sphere Spec…
