Compact Goniophotometer

The LSG-1200A compact goniophotometer is designed for measuring luminous intensity distribution curves, intensity data, and beam angles for Chip LED, LED Module, LED Spotlight, and other lighting sources with a spread angle not exceeding 180 degrees. It offers an optional function for integration with a Digital Power Meter (LS2012 DC & AC Power Meter or LS2050 Harmonic Analyzer Power Meter) and LSP-500VARC AC Power Source.

Standards: LM-79-19 “Optical and Electrical Measurements of Solid State Lighting Products”, EN13032-1 “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”.
